新型蔬菜专用肥在叶菜上的使用效果

Effects of the New-type Specific Fertilizers on Leaf Vegetables

新型蔬菜专用肥采用N、P、K和含粘土矿物、Ca、Mg及其他微量元素的营养型土壤改良剂复配而成。大田试验表明,在三种叶菜上的增产效果优于进口复合肥和国内常用的复混肥料,增产率分别达6.52%～13.2%和6.4%～27.5%,收益分别增加13.3%～23.6%和7.2%～32.9%,施用新型蔬菜专用叶面肥具有提高土壤pH值,增加代换性Ca和Mg,提高土壤有效N、P、K的效果。

The effect of the new-type specific fertilizer was superior to that of the imported compound fertilizer(15-15-15),the increment of the yield6.52%-13.2%and6.4%-27.5%respectively,and the cor-responding income by13.3%-23.6%and7.2%-32.2%respectively.Application of the new-type specific fertilizer could raise pH,exchangeable Ca and Mg,and available content of N,P,K of soil.
