1 材料与方法1.1 试验处理 本试验为N、K二因素试验,每个因素按每hm~2施用量不同各设定三个水平,其中: N素三水平为A_1(225kg)、A_2(300kg)、A_3(375kg),基肥:腊肥:薹肥按5:2:3运筹; K_2O三水平为B_1(225kg)、B_2(300kg)、B_3(375kg),基肥:腊肥按5:5运筹; 对照CK仅施有机肥,施肥量为每hm~2折纯N300kg,肥种为菜籽饼,其中基肥用3000kg,腊肥用1350kg,二因素处理磷肥以每hm~2施钙镁磷肥300kg作基肥。
1 Materials and Methods 1.1 Test Treatment The test for the N, K two-factor test, each factor for each hm ~ 2 different application rates set three levels, of which: N three levels of A_1 (225kg), A_2 (300kg ), A_3 (375kg), basal fertilizer: brown fat: sedge fertilizer by 5: 2: 3; K_2O three levels: B_1 225kg, B_2 300kg, B_3 375kg, ; CK was only organic fertilizer, the amount of fertilizer per hm ~ 2 off pure N300kg, fertilizer for the rapeseed cake, which base fertilizer with 3000kg, wax fertilizer with 1350kg, two factors to deal with phosphate fertilizer per hm ~ 2 applied calcium magnesium phosphate 300kg As a base fertilizer.
