氮肥运筹对不同生育期晚稻品种产量及氮素吸收利用的影响
Effects of Nitrogen Fertilizer Planning on Yield and Nitrogen Absorption and Utilization of Late Rice Varieties with Different Growth Duration
摘要
Abstract
The responses of six late rice varieties with different growth duration to different ratios of basic tillering fertilizer to panicle fertilizer, 7 ∶ 3 and 6 ∶ 4, were studied.The results showed that the yield of early maturing varieties (growth duration ＜110 d ) in 7 ∶ 3 treatment were higher than those in 6 ∶ 4 treatment, while among middle maturing varieties (growth duration 110～ 120 d) and late maturing varieties (growth duration＞ 120 d), some gained higher yield in 7 ∶ 3 treatment and others gained higher yield in 6∶ 4 treatment.There was no evident correlation between effect of different ratios of basic tillering fertilizer to panicle fertilizer on nitrogen absorption and utilization and maturation period of varieties.关键词
