1精细整地深耕细整地创造良好的土壤条件是保证玉米苗全、苗齐、苗壮夺取玉米丰产的基础。深耕的作用:一是改善土壤物理性状提高蓄水保墒透气能力,深耕能够打破长期浅耕所造成的犁底层。二是熟化土壤增加养分深耕可以将部分生土翻于地表面经过冻融交替风吹日晒而熟化使土壤中的矿物质释放出来增加土壤速效养分含量。三是有利于增施有机肥料培肥地力深耕为大量增施有机肥料提供条件,可以实现深施底肥。四是翻埋根茬杂草
A fine preparation of deep plowing to create a good soil conditions to ensure that the whole corn seedling, Miao Qi, Miao Zhuang to seize the basis of high yield corn. Deep plowing role: First, improve the physical properties of soil to improve the permeability of water storage capacity, deep plowing to break the long-term shallow plow caused by the bottom layer. Second, maturity of soil to increase nutrients Deep plowing can turn some of the raw soil to the surface of the ground after the freeze-thaw alternating sun and maturation of soil minerals released to increase soil available nutrient content. Third, it is conducive to the application of organic fertilizers fertilizing soil plowing for a large number of additional organic fertilizer to provide the conditions, you can achieve deep base fertilizer. Fourth, burying root stubble weeds
