近几年,我社农作物产量增长缓慢,其原因:土壤氮磷钾三要素含量低,有机质不足1%,农家肥质量差且多数是撒施浅耙,养分损失多,施用化肥后土壤结构变坏.为了寻求解决办法,我们进行了早熟玉米复种绿肥柽麻试验.一、试验方法和结果采用正交法对早熟玉米进行多因子试验,摸索高产栽培技术. In recent years, the output of our cooperative crop has been slow to grow. The reasons are as follows: the contents of N, P and K in soil are low, the content of organic matter is less than 1%, the quality of farmyard is poor and most of them are shallow rakes, nutrient loss is more. Bad .In order to find a solution, we conducted a trial of maize multiple cropping green manure hemp. First, the test methods and results using orthogonal method of premature corn multifactorial test to explore high-yielding cultivation techniques.
