摘要
对清水河县北堡乡14个村主要经济作物的土壤养分状况进行测定,结果表明:全乡农田养分含量整体呈中下等水平;有效磷和速效钾的含量可达到中等等级;碱解氮和有机质含量较低,处于很缺乏状态;pH呈碱性。谷子对磷(P2O5)的需要量最大,玉米对氮(N)的需要量最大,土豆对钾(K2O)的需要量最大。
Through determinating the soil nutrient of main economic crops in 14 villages in Beipu Town, Qingshuihe County, the results show that the farmland nutrients are in the position of middle or lower level in the whole, the content of available phosphorus and potassium is at the middle level, the content of available nitrogen and organmic matter is very lack, and pH value presents alkaline. The most requirement for millets is P205. The most require- ment for corns is N. And the most requirement for potatoes is K2O.
