果上丰高光效高肥效生物制剂对梨杏树的抗冻增产效果
Effect of Guoshangfeng High Light Efficiency and High Fertilizer Efficiency Biological Agent on Anti-Freezing and Increasing Yield of Pear Tree and Apricot Tree

我国北方春季频发的倒春寒灾害，给当地果树的生产造成巨大的损失。果上丰高光效高肥效生物制剂的出现，在使果树高产优质的同时，在应对倒春寒的灾害中效果如何呢？本次试验在梨、杏树上的试验表明，在不同品种的梨树上平均可减少落花落果率19.6%，平均提高增产率61.4%；在杏树(大接杏)的试验表明，落花落果率减少27.7%，提高增产率89.4%。说明果上丰生物制剂在高光效、高肥效的作用下，防霜抗冻的能力也是十分明显的。这就为北方果农在应对倒春寒的灾害中，开辟了一条方便、快捷和高效的通道。
The frequent inverted cold disaster in spring in northern China has caused huge losses to local fruit production. The appearance of guoshangfeng High light efficiency and high fertilizer efficiency biological agents, while making fruit trees high yield and quality, in dealing with the disaster of reverse cold effect? In this experiment, the results of pear trees and apricot trees show that in different varieties of pear trees, the average flower and fruit drop rate can be reduced by 19.6%, and the average yield increase rate can be increased by 61.4%. The experiment on apricot tree showed that the drop rate of flower and fruit decreased by 27.7% and the increase rate of yield increased by 89.4%. The results showed that the anti-frost and anti-freezing ability of guoshangfeng biological agent was also very obvious under the action of high photoefficiency and high fertility effect. This has opened up a convenient, fast and efficient channel for northern fruit farmers to deal with the disaster of inverted cold.
