| 摘 要： | 根据氯对作物和土壤的影响,表明南方可以在各种作物的耐氯极限内施用含氯化肥,并需配合施用石灰和含钙磷肥;而北方旱区,特别是西北地区合理施用含氯化肥应根据每茬作物吸收带走的氯量,确定一个轮作周期内施用含氯化肥的量,保持土壤氯素的平衡,不致使土壤盐渍化。氯化铵可以就近施用,缺钾作物也能以含氯钾肥予以补充。此即本文所述氮素平衡施肥原理。

| Abstract: | According to the influence of chlorine on crops and soil, the chlorine fertilizer can be used in various crops within endurable limits in the south area,which must be mixed with lime and P fertilizer containing Ca. In the dry north area, particularly in north west area, the rational use of chlorine fertilizer is to calculate the quantity of Cl fertilizer in the light of chlorine quantity absorbed by crops in one rotation period,to preserve chlorine balance in the soil in order to avoid salinized soil, to apply the NH_4Cl nearby and to supplement K in time to K-lacking crops. |
