氮肥运筹对超级稻五丰优T025养分吸收、转运和分配的影响
Effects of Nitrogen Application on Nutrient Absorption, Transportation and Distribution in Super Rice Wufengyou T025
摘要
Abstract
Late super hybrid rice Wufengyou T025 was used to investigate the effects of different nitrogen (N) application on absorp-tion, transportation and distribution of nutrient and yield in rice. The results showed that there was an obvious interaction N applica-tion on N, phosphorus(P), potassium(K) absorption and transfer at different growth stages under N application, and the reasonable N application is benefit to promote the absorption of various nutrients and transfer. In this experiment, the nutrient transfer amount and the contribution rate of nutrient to panicle of leaves and stem-sheaths were increased with the increase of the percentage of tillering fertilizer in N fertilizer. The amount of N, P, K nutrient transfer increased up to 17.1%, 21.2%and 14.8%, respectively. Under the to-tal pure nitrogen amount of 195 kg/hm2,the best model of the N application is basal(50%), tillering(20%), and panicle(30%).关键词
