磷肥种类及用量对土壤磷素有效性和棉花产量的影响

Effects of Phosphate Fertilizer Type and Amount on Soil Phosphorus Availability and Cotton Yield

棉花生长发育过程中,磷是重要的营养元素之一。针对两种不同磷肥不同用量对于土壤磷素有效性以及棉花产量的影响进行田间试验,探讨合理的磷肥种类和用量。

Phosphorus is one of the most important nutrients in growth and development of cotton. Field experiment was conduc- ted to test effects of two different phosphorus fertilizers and different amount on soil phosphorus availability and cotton yield. Rea- sonable phosphate fertilizer type and amount were discussed.
