摘要
根据黄土区土壤养分含量和枣树对N,P2O5和K2O的吸收量,设计出一种该区枣树专用复混肥,其配方比为14∶8∶8。确定了在养分平衡基础上的适宜施肥量,试验表明连续3年平均产量为4 525.0 kg/hm2,比对照提高49.56%,肥料效果十分显著。
According to soil nutrient content and absorbing volume for N, P2O5 and K2O, a kind of Jujube special compound fertilizer was designed, the formula ratio is 14 ： 8 ： 8 ; and suitable fertilizing amount was decided on the basis of nutrient equilibration. Test shows fertilizer effect is notable, the average yield of continuous 3 years was 4524. 0 kg/hm^2, raising 49.56% compared with CK.
