杂交早稻栽插方式对产量和米质性状的影响

Effect of transplant way in early hybrid rice on yield and quality

杂交早稻采用４种栽插方式的稻谷产量、稻米的碾磨品质和外观品质存在差异。采用适当稀植、株行距大的１０ｃｍ×２３３ｃｍ方式能协调植株个体与群体生长的关系，保持稻株适宜的营养面积和空间，促进分蘖成穗，增加穗粒数，减少垩白率和垩白面积。

There are differences on rice milling quality and outward appearance quality when early hybrid rice are cultivated in 4 different methods. Adopt proper planting sparsely, big plant and row spacing(10cm×23 3cm) can coordinate the relation between individuals and population growth. Keep a suitable area of trophic uptaking and space of rice strain, accelerate tillering and earbearing, increase the grains per ear, decrease the chalkiness and chalkiness score and improve the head milled rice yield.
