石灰氮的土壤改良作用及对蔬菜的施用效果研究

Effects of lime-nitrogen on soil ameliorate and vegetables production

石灰氮可以纠正土壤酸化 ,施用后使盐基浓度不上升 ,并可抑制 NO3-生成 ,减少氮素流失 ,还具有除草、杀灭病虫害的功效 ,在菠菜、大豆、草莓上施用效果优于尿素 ,氮素利用率较高 ,既提高了产量 。

WT5”BZ]Lime nitrogen can prevent soil acidification. Soil conductance hardly varied and formation of NO 3 - was inhabited after lime nitrogen is applied, also some pest and virus in soil and weeds could be killed. Yields were raised and quality was improved when it was applied on spinach, soybean and strawberry. N utilization by spinach from lime nitrogen was higher than urea. [WT5”HZ]
