【摘要】 稻株个体生长障碍是水稻再高产的限制因素 ,运用最少基本苗增产原理形成的水稻单本植栽培法 ,能最大限度消除其个体生长障碍 ,使之充分发挥稻株自身的生长能力 ,大幅度增加有效分蘖天数 ,提高了分蘖力和分蘖成穗率 ,使之稳定高产栽培的穗群体 ,通过提高个体质量 ,使平均穗粒数增加 2 3粒 ,结实率提高 5 % ,千粒重有所增加 ,产量提高 2 6 % 30 %。更多还原

【Abstract】 Individual plant growth obstacle" of riec isthe Limited element for rice super-high yield. The single plant transplantation formed from "the pronciple of minimum basic plants in unit area could incease rice yield" can greatly decrease the "individual plant growth obstacle", and the growth capacity of rice plant itself can be dug up completely. This method could enlarge the duration of effective litters, increase the capacity of tiller formation and head ratio. Through improving individual plant quality, this method could increase the average spikelet number perhead by 23, fulfilled grain ratio by 5% and yield by 26%~30%.更多还原
