1.提升土壤肥力小麦高产与土壤肥力关系极大。高产栽培对土壤要求是:土层深厚、有机质丰富、营养充足、土壤结构良好、保水能力强、通气性好、土壤耕作层有机质含量在1.2%以上,全氮含量在0.08%以上,碱解氮每千克在70毫克以上,速效磷每千克在15克以上,速效钾每千克在100克以上。小麦全生育期吸收的养分,有2/3来自土壤储藏养分,有1/3来自当季施用肥料。提升土壤肥
1. To enhance soil fertility Wheat yield and soil fertility great relationship. High-yielding cultivation of soil requirements are: deep soil, rich organic matter, adequate nutrition, good soil structure, water retention capacity, good aeration, tillage soil organic matter content of more than 1.2%, total nitrogen content above 0.08%, alkaline hydrolysis nitrogen More than 70 milligrams per kilogram, available phosphorus more than 15 grams per kilogram, available potassium per kilogram at 100 grams or more. Two and a half percent of the nutrients absorbed by the wheat throughout the growing season come from soil storage nutrients and about one-third come from seasonally-applied fertilizers.
