不同栽培方式对水稻农艺性状及产量的影响

Effects of Different Cultivation Methods on Agronomic Traits and Yield of Rice

为了进一步提高水稻单产水平,研究不同栽培方式对水稻农艺性状及产量的影响,2014-2015年对水稻不同栽培方式进行了同田对比试验。试验结果表明,宽窄行错窝栽培方式的应用对水稻农艺性状及产量会产生重要的影响。通过改变水稻栽培方式,大幅的提高栽插密度,使稻株空间得到合理的配植,改善稻株光养供给条件,协调个体与群体之间的矛盾,对培育健壮个体,优化群体结构,建立"库"大、"源"足、"流"强协调发展的高产群体,增加水稻单位面积有效穗和实粒数,最终实现水稻高产具有非常重要的作用。

In order to further increase the yield of rice, studied the effects of different cultivation methods on agronomic traits and yield of rice, different cultivation methods in 2014--2015 was tested. The results showed that the apply of wide--narrow row and staggered hill cultivation method have a big effect on agronomic traits and yield of rice. By changing the rice cultivation method, significantly improve the planting density, optium the rice plants space more reasonable, improve the rice plants light supply conditions, coordinate the contradiction between individual and group, to cultivate healthy individuals, optimize group structure, establish a ＂sink＂, ＂source＂, ＂flow＂ the coordinated development of high--yielding group, increasing effective panicles per unit area of rice and grain number, finally play a very important role on increase the yield of rice.
