| 摘 要： | 在磷、钾素含量较高的黄红壤上研究了连续施用磷钾肥对油菜产量、养分吸收和经济效益的影响。结果表明:施用磷钾肥,可以显著提高油菜产量,增产幅度达45.3%~180%,磷肥效应起主导作用。连续施用磷钾肥有利于养分的协调供应,提高了油菜植株的养分含量和养分吸收量。磷钾肥的施用还能大幅度提高经济效益,三季油菜纯利润平均增加了1 372.8~1 851.1元/hm2。

| Abstract: | Effect of continuous application of phosphorus and potassium fertilizer on rapeseed yield and nutrient uptake in yellow - red soil with high available P and available K was studied. The results indicated that application of P and K fertilizer can notably increase rapeseed yield by 45.3% - 180%. The yield response to P plays a leading role. Continuous application of P and K fertilizer were beneficial to provide balanced nutrient, increased nutrient content and nutrient uptake in rapeseed. Application of P and K fertilizer could raise net income of rapeseed production substantially. The average net income in the three seasons was increased by 1 372. 8 - 1 851. 1 yuan/hm^2. |
