一、苹果灾后管理技术 (一)苹果水淹后,果园积泥深的,易引起根系死亡、早落叶,可先除去树盘或株间淤泥,其它淤泥以后再除去。果园积泥较浅的,可进行全面翻地晾墒,降低土壤含水量,改善土壤通气条件。 (二)水灾后,因根系生长受抑制,致使部分死亡,叶片光合受阻。应及时追施肥料,以喷施为主,多次喷尿素(0.3～0.5%),磷酸二氢钾(0.3%),多元复合微肥。此外高美施、绿风95等肥均能促进光合作用。
First, apple disaster management technology (A) apple flooded, orchards deep muddy, easy to cause root death, early leaves, you can first remove the tree plate or between the silt, and then remove the other silt. Orchard sludge shallow, can be fully open air moisture, reduce soil moisture, improve soil aeration conditions. (B) After the floods, due to inhibition of root growth, resulting in some death, leaf photosynthesis blocked. Should promptly topdressing fertilizers to spray-based, multiple urea spray (0.3 ~ 0.5%), potassium dihydrogen phosphate (0.3%), multi-element composite fertilizer. In addition, the high Meishi, Green Wind 95 and other fertilizer can promote photosynthesis.
