Effect of Phosphate Fertilizer on Rice Yield Increasing on Dark Brown Soil and Its Appropriate Amount Research in Ning'an City
摘要
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 P2P1P3P4.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.关键词
