摘要
试验表明,钙镁磷肥在含磷量较低的中低产石灰性土壤中,配合一定的氮肥施用,小麦、玉米分别比对照增产97.4%、51.5%,增产效果显著;如与50%水溶性磷肥混合施用,增产效果更佳.
The experimental results has shown that the calcium, magnesium and phosphate fertilizer is a excellent phosphoric fertilizer. When it was applied in medium-low yields and low phosphorus content calcareous soil with some nitrogen manure, the wheat and corn per mu yields increased by 97.4 and 51.5 Per cent respectively.It will be more significant that the calcium, magnesium and phosphate fertilizer is applied with 50% water-soluble phosphoric fertilizer.
