GPIT生物制剂对雹灾后玉米再生效果的试验研究

Experimental Study on Regeneration Effect of GPIT Biological Preparation on Maize after Hail Disaster

摘要: 每当夏季冰雹给农作物带来的灾害损失不可小觑，但至今在农业生产上也没有一个令人满意的行之有效的防御方法。GPIT生物制剂在高光效的作用下能使农作物达到高产、优质、高抗的效果，为了验证GPIT生物制剂的高光效作用对农作物雹灾后产生的再生效果，从而挽回因雹灾造成的部分损失，提高雹灾后农作物单位面积产量，我们以玉米为例，对雹灾后玉米进行了3次不同浓度的GPIT生物制剂的根外喷施试验。结果表明，在11项数量性状和3项质量性状上均出现了明显效果，使最终玉米单位面积的产量从雹灾造成41%的损失中，挽回了27%的损失，只造成14%的损失，挽回的损失是最终造成损失的1.9倍。GPIT生物制剂对雹灾后玉米再生效果的试验结果，为今后各种农作物应对因雹灾带来的自然灾害，间接的提供了一条行之有效的途径。

Abstract: Whenever the summer hail to the crop disaster loss cannot be underestimated, but so far in agricultural production there is no a satisfactory effective defense method. GPIT biological agents under the action of high photosynthetic efficiency, can make the crop high yield, high quality, high effect, in order to test the effect on crops GPIT biological preparation of high photosynthetic efficiency re-generation effect after hailstorm, and save partial loss caused by hail, increase crop yield per unit area after hailstorm, we take corn as the example, three different concentrations of corn after hail-storm GPIT biological agents of the root of the spraying test. The results showed that there were obvious effects on 11 quantitative characters and 3 quality characters, which made the final corn per unit area and yield recover 27% of the 41% loss caused by hail disaster, and only 14% of the loss caused by hail disaster. The recovered loss was 1.9 times of the final loss. The experimental results of GPIT biological agents on maize regeneration after the hail disaster indirectly provided an effec-tive way for various crops to deal with the natural disasters caused by the hail disaster in the future.
