一、土肥水管理1、改良土壤秋季进行深翻60cm,施入有机肥及作物秸杆,以后每年秋季在上一年深翻的基础上向外深翻扩穴一次。深翻时,保护1cm 以上粗的根。同时第二年春季地面覆盖杂草或作物秸杆。这种方法可有效地改善土地的理化性质,提高梨园土壤的保水、保肥和供水、供肥能力,增加吸收根的数量和根系密度。2、合理施肥基肥:每年秋季梨果采收后,结合深翻亩施有机肥5000kg,氮磷钾三元复合肥25kg 及适量微肥。也可以采用放射沟施肥,施后覆土浇水。
First, the soil and fertilizer water management 1, soil improvement Deep plowing 60cm, applied organic fertilizer and crop straw, after the fall of each year in the previous year on the basis of deep plowing doubled again. Deep flip, the protection of more than 1cm thick roots. While the second spring ground cover weeds or crop straw. This method can effectively improve the physical and chemical properties of the land, improve the water retention, fertilization and water supply, fertilizing capacity and the number of absorbed roots and root density of the pear orchard soil. 2, a reasonable fertilization basal fertilizer: pear harvest each fall, combined with deep turning acres of organic fertilizer 5000kg, NPK ternary compound fertilizer 25kg and the amount of fertilizer. Radiation ditch can also be used fertilizer, Shi Tu soil after watering.
