有机水溶肥料在高海拔地区大豆上的应用效果
Application Effect of Organic Water-Soluble Fertilizers on Soybeans in High-Altitude Areas

在湖北利川海拔1100 m上下的2个不同地点和土类上，通过正规的田间小区试验，验证了有机水溶肥料这种新型叶面肥料在高海拔地区大豆上的应用效果。试验结果表明，在大豆生育中期用有机水溶肥料800倍液喷雾三次(每次间隔10~15天)，可使大豆显著增产，比常规施肥亩增产大豆20 kg左右，净增收100元以上，增幅超过15%。该肥主要促进了大豆果荚数量、株粒数及百粒重提高，从而实现增产，可在相似区域的大豆种植上大面积推广应用。
The application effect of organic water-soluble fertilizer, a new type of foliar fertilizer, on soybeans in high-altitude areas was verified through regular field trials at two different locations and soil types at an altitude of around 1100 meters in Lichuan, Hubei. The test results showed that in the middle growth period of soybeans, three times of spray with 800 times of organic water-soluble fertilizer (every 10~15 days) could significantly increase the yield of soybeans. Compared with conventional fertilization, the yield of soybeans per mu increased by about 20 kg, and the net income increased by more than 100 yuan, an increase of more than 15%. This fertilizer mainly promotes the increase in the number of soybean pods, the number of seeds per plant, and the weight of one hundred seeds, thereby achieving yield increase. It can be widely promoted and applied in soybean planting in similar areas.
