Application of environmental materials in agricultural production and environmental treatment

HUANG Zhan-Bin,SUN Zai-Jin,

Abstract: Environmental materials include the essentials for human beings with the least environmental load and highest use function. In recent years, a great deal of focus has been directed on environmental material application in agricultural production and environmental treatment. In agricultural production, environmental materials have been major actors for improving soil mi-cro-environment and enhancing crops growth. It has also included development of environment-friendly chemical fertilizers, pesti-cides and cover films. In agro-environmental administration, the materials have been used in agro-ecological degradation and envi-ronmental pollution control. This paper introduced the connotation of environmental materials and analyzed research and application in agricultural production and the environmental treatment. These functions mainly included three aspects: agricultural drought resis-tance and water-saving, soil heavy metal pollution prevention and saline-alkali soil amendment. The application of environmental materials in agricultural drought resistance and water-saving was mainly in super absorbent polymer (SAP) of soil processes and leaf resistance transpirants. The four action principles of SAP included water absorption, retention and release; improving soil and water conservation; raising use efficiency of fertilizers, pesticides and other chemicals; and raising plant water-use efficiency by adjusting physiological functions on water balance. Synthetic technology of SAP had greatly advanced, while SAP application technology should be strengthened. Although leaf resistance transpirant technology had also advanced, research was still at trial stage and even only humic acid products had been used. Research and application of environmental materials in restoration of heavy metal polluted soil was relatively more extensive. Considerable progress had been made on bio-restoration and chemical solidification technologies. Potential risks of environmental material applications in heavy metal polluted soil restorations were little studied. Application of en-vironmental materials in saline-alkali soil improvements was mainly on calcium-containing materials (e.g., gypsum) and acid-containing materials (e.g., humic acid). Such improvement effects of these materials were much better when the materials were combined with polyacrylamide (PAM). In addition, this paper also pointed out three important research disciplines of environmental materials: enhancement of new forms of environmental materials, strengthening of applying fundamental and effect evaluation stud-ies, and reinforcement of comprehensive research on environmental materials, bio-technology and agro-engineering technology.

Abstract: Capsicums were planted in pots and dealt with aquasorb and three levels of water controlling 100% field capacity of soil water (FC), 75% FC, and 50% FC]. The results show that the application of aquasorb can obviously improve the growth and water use efficiency of capsicums. The leaf area, leaf number, plant height, biomass and water use efficiency of capsicums with aquasorb treatment are prior to those of non-aquasorb treatments. At the same time, high-water supply can improve the growth of capsicums while low-water supply delays its growth rate. The data processing result by grey correlation analysis show that the close extents of relation among the water consume and biomass, leaf area, leaf number, plant height, dry biomass content and root crown ratio are different due to applying aquasorb or not. The relation sequence of applying aquasorb is biomass>dry biomass of stem and leaf>dry biomass of root>leaf number>plant height>leaf area>root crown ratio>dry biomass content, but the relation sequence without aquasorb is biomass>leaf number>dry biomass of stem and leaf>dry biomass of root>plant height>leaf area>dry biomass content>root crown ratio

Abstract: The paper analyzes the response of plant growth, physiological process and water use efficiency, etc. on different water conditions under CO2 concentration raising. The results show that CO2 raising will produce positive effect on plant growth under water deficient conditions, such as increasing of plant leaf area, dry biomass, and root / shoot ratio. Meanwhile, it can improve stoma physiology, reduce water transpiration, raise water potential of plant leaf, and enhance grain yield of crop and the water use efficiency, and compensate the adverse effect of water deficiency on plant growth and water use efficiency. This has an important meaning on waler saving and yield increasing of agriculture.

Abstract: Under the same irrigation management,plant height,leaf area,drygrain weight and water use efficiency(WUE) always differ due to differences in water quality.Pot experiment was conducted with fresh water(F) as the control treatment to compare the effect of reclaimed water SecondGrade(S),Third-Grade(T),and OriginalSewage(O) from Beijing Gaobeidian sewage water treatment plant] irrigation on the growth and WUE of maize(Zea mays L.) and soybean(Phaseolus vulgaris L.).From the results,it is observed that S inhibits maize growth,while T promotes maize growth in the breeding stage.S and T reclaimed water irrigation shows a promotive effect in breeding and flowering stages,while no effect in the harvest stage of soybean.With regard WUE,a set of reclaimed water shows an inhibition effect in maize breeding stage,which gradually changed into a promotive effect after jointing stage.Another set of reclaimed water is observed to have a promotive effect in soybean breeding stage,which also gradually faded out after the flowering stage.In conclusion thus,third-grade reclaimed water(T) irrigation has beneficial effect on the growth and WUE of maize in all growth stages.Second-grade reclaimed water(S) irrigation inhibits growth and WUE of maize in breeding stage,but promotes growth and WUE after the jointing stage.The two grades of reclaimed water irrigation of soybean benefit all growth stages,and not remarkely influence WUE.

Abstract: 通过盆栽试验,以旱作冬小麦(Triticum aestivum)为材料,分别在拔节和抽穗期对分蘖进行人工干扰,来模拟不可预测的自然干扰,对冬小麦分蘖冗余的生态学意义以及减少这些冗余对水分利用效率影响进行研究。设置3个处理:从拔节期开始剪去所有小的分蘖,仅保留主茎和一个大的分蘖(A);在拔节期剪去主茎和两个大的分蘖,保留所有小的分蘖(B);在孕穗期剪去主茎和有效分蘖,保留无效分蘖(C)。没有被干扰的植物作为对照(CK)。通过花期测定叶片的叶绿素含量、叶绿素荧光参数、气孔导度和蒸腾速率等生理指标来评价植物的生理与生化活性。结果显示,在拔节期和抽穗期去除主茎和大蘖后,无效分蘖的生理活性被激活,开始执行有效分蘖的功能。到花期时,这些无效分蘖已经在生理活性上满足了补充和替代有效茎的要求。虽然株高和穗的整齐度、穗数和产量显著下降,但并没有防碍小麦的繁衍子代,因此,正是这些由早期“无效分蘖”补充而来的有效茎,避免了小麦绝种的风险。 而在拔节期去除无效分蘖后,对小麦产量没有显著影响,但提高了水分利用效率,和对照相比水分利用效率提高了10%。因此,可以认为小麦在分蘖上存在着对水分利用不利的生长冗余,减少这些冗余有望节约用水、提高作物的水分利用效率。

Abstract: The effects of water-retaining agent (60 kg·hm-2) and nitrogen fertilizer (0, 225, and 450 kg·hm-2) on the leaf photosynthetic characteristics, chlorophyll content, and water utilization of winter wheat at jointing and grain-filling stages were studied under field conditions. In all treatments, the net photosynthetic rate, stomata conductance, intercellular CO2 concentration, water use efficiency, and chlorophyll content were greater at grain-filling stage than at jointing stage. Under nitrogen fertilization but without water-retaining agent application, the water use efficiency (WUE) of single leaf at jointing stage increased with increasing nitrogen fertilization rate, while the net photosynthetic rate, stomata conductance, intercellular CO2 concentration, and transpiration rate decreased after an initial increase. The chlorophyll content was the highest under 225 kg·hm-2 nitrogen fertilization. In the treatments of water-retaining agent application, the intercellular CO2 concentration decreased with increasing nitrogen application rate, but the net photosynthetic rate, transpiration rate, and WUE increased. The application of water-retaining agent or its combination with nitrogen fertilization increased the chlorophyll content, but excessive nitrogen fertilization had lesser effects. At grain-filling stage, applying nitrogen fertilizer alone significantly increased the net photosynthetic rate and WUE, but decreased the stomata conductance, intercellular CO2 concentration, and transpiration rate. The chlorophyll content increased with increasing nitrogen application rate. After applying water-retaining agent and with the increase of nitrogen fertilization rate, the photosynthetic rate and WUE decreased after an initial increase, while the intercellular CO2 concentration and transpiration rate were in adverse but still lower than those without water-retaining agent application. The stomata conductance increased with increasing nitrogen fertilization rate. The chlorophyll content increased significantly under the application of water-retaining agent, but somewhat decreased under the combined application of water-retaining agent and nitrogen fertilizer. The application of both water-retaining agent and nitrogen fertilizer increased the 1000 grain mass, grain yield, and water production efficiency of winter whe at significantly, with the best effect in the treatment of water-retaining agent with 225 kg·hm-2 nitrogen fertilization.

Abstract: Application of environmental materials is a vital remedial measure of heavy metal lead (Pb) and cadmium (Cd)) contaminated soils. To explore the effects of environmental materials on plant growth and quality and to enhance remediation of Pb and Cd contaminated soils, a pot experiment was setup in greenhouse conditions. The experiment analyzed soil properties, growth and quality as well as Pb and Cd contents of maize (Zea mays L.) in Pb-Cd contaminated soils. Different environmental treatments, including single environmental materials treatments e.g., humus (HA), polymers (SAP), coal-derived composites (FM) and powder minerals (FS)], and composite treatments of environmental materials were selected in heavy metal Pb and Cd contaminated soils. The results indicated that F22 (FM+SAP), F23 (FS+SAP) and F32 (HA+SAP+FS) composite treatments promoted stronger maize growth at seedling stage than that of the control. Maize crude ash in all the treatments with environmental materials was less than that of the control. Also maize crude starch in single environmental material treatments was higher than that in composite environmental material and control treatments. By comparison, single FM and combined F33 (SAP+FM+FS) and F4 (HA+SAP+FM+FS) treatments had a significant inhibition effect on maize Pb uptake in Pb-Cd contaminated soils. Similarly, single FM and FS and composite F33 (SAP+FM+FS) environmental materials treatments had a significant prohibition effect on maize Cd uptake in Pb-Cd contaminated soils. Thus the application of environmental materials could improve soil physical and chemical properties and inhibited crop heavy metal uptake.

Abstract: A field experiment was conducted to determine the water use characteristics of winter wheat at different growth stages under application of water-retaining agent (60 kg·hm -2) and nitrogen fertilizer 0, 225 kg(N)·hm-2, and 450 kg(N)·hm -2]. The field experiment investigated soil moisture, winter wheat biomass accumulation, water use at different growth stages as affected by wa-ter-retaining agent and nitrogen fertilizer. The results indicated that soil moisture, biomass accumulation, yield and water use effi-ciency (WUE) of winter wheat increased after water-retaining agent and nitrogen fertilizer application. Compared with other treat-ments, soil moisture under treatments of 450 kg(N)·hm -2 of nitrogen fertilizer, 60 kg·hm -2 of water-retaining agent, and 60 kg·hm-2 of water-retaining agent plus 450 kg(N)·hm -2 nitrogen fertilizer increased. There was a significant increase in the accumulation of above-ground winter wheat dry-matter with increasing nitrogen application rate without water-retaining agent. However, winter wheat dry-matter accumulation decreased under water-retaining agent plus excessive nitrogen fertilizer treatment. Winter wheat dry-matter biomass increased from jointing to harvest and the increase was more obvious at the later growth stage under wa-ter-retaining agent with 225 kg(N)·hm-2 nitrogen fertilizer treatment. From sowing through jointing, booting and grain-filling stages, WUE was boosted by increased nitrogen fertilizer application rate. WUE increased significantly under water-retaining agent plus nitrogen fertilizer treatment. Also from grain-filling to harvest, WUE increased by 53.8% and 57.8% over the control (CK) under 450 kg(N)·hm-2 nitrogen fertilizer and water-retaining agent plus 225 kg(N)·hm-2 nitrogen fertilizer treatments, respectively. In conclu-sion therefore, the yield and WUE of winter wheat increased and with the best effect under 60 kg·hm-2 water-retaining agent plus 225 kg(N)·hm-2-2 nitrogen fertilizer application.
