- 摘要:
- 为探讨黑龙江省暗棕壤土水稻施磷肥的适宜用量，在宁安市对水稻磷肥增产效果及其适宜用量进行了试验研究。结果表明：磷肥对水稻生长发育和产量有明显的促进作用；施磷的各处理增产由高到低顺序为：P2>P1>P3>P4。磷的适宜用量为P2O590 kg·hm-2，增产17.2%，增效1 527元·hm-2。磷肥用量过低不能满足水稻高产优质的需要，过高影响水稻正常生长发育。
- Abstract:
- In order to provide scientific basis for fertilization on dark brown soil in Heilongjiang province,the effect of phosphate fertilizer on rice yield increasing and the appropriate amount experiment was conducted in Ning’an city.The results showed that improving effect of phosphorus on rice growth and yield was significant;the order of yield increasing with phosphorus treatment from high to low was P2>P1>P3>P4.The appropriate amount of phosphorus P2O5 was 90 kg·hm-2,increasing yield by 17.2%,increasing benefit 1 527 yuan·hm-2.It also indicated that low amount of phosphorus could not meet the needs of high yield and superior quality of rice,but excessive high amount could affect the normal growth and development.
