施氮水平对水稻生长与产量特性的影响
Effects of Nitrogen Fertilizer Level on Grow and Yield Characteristics of Rice
摘要
Abstract
Taking Songjing No .9 as material ,the effects of nitrogen fertilizer level on grow characteristics ,yield and yield components of rice were studied .The results indicated that nitrogen fertilizer was good for increasing of rice height and tiller ,but too much nitrogen fertilizer would lead to more invalid tillers .Using nitrogen fertil-izer could increase yield ,while harvest index would descend .Spike number ,full grainper spike and 1000-grain weight were raised by using nitrogen fertilizer ,polybasic linear regression equation taking nitrogen fertilizer a-mount as dependent variable ,spike number ,full grain and 1000-grain weight as independent variable was set up at the same time .关键词
