不同麦秸秆还田量对机插水稻生长发育和产量的影响
Effects of Different Wheat(Triticum aestivum Linn.) Straw Returning Amount on Growth, Development and Yield of Machine-transplanted Rice (Oryza sativa L.)
摘要
Abstract
[ Objective] The aim was to study the effects of different wheat straw returning amount on production of machine - transplanted rice. [ Method] The test rice varieties were Early - maturing and late - season japonica rice, Nanjing 44 and Yangjing 4227. The split plot design was conducted. Nanjing 44 and Yangjing 4227 were two main plots, and each main plot had 3 split plots, control (no straw returning), half of wheat straw returning and total wheat straw returning. [Result] Under the same application amount of basic fertilizer, tillering fertilizer and earing fertilizer, with the increasing of wheat straw returning amount, at the early period, rice tillering put off, and tiller number, leaf area index, dry matter accumulation and spike number per unit area were all lower than those of control, but at he middle and late period, leaf area index, dry matter accumulation and spike number per unit area had a opposite change law; with the increasing of wheat straw returning amount, rice grain per spike, 1 000 - grain weight, ripening rate and yield rose; and organic matter, alkali-hydrolyzable nitrogen and total nitrogen content in soil after straw returning were higher than those of control and before test. [Conclusion] The study provides a theoretical basis for planting rice after straw returning in a large scale.关键词
