Abstract:

Under super-sparse of nutrition bowl mechanical transplanting, the yield components, tiller dynamic, LAI and dry matter accumulation of population of different yield were studied, using indica-japonica hybrid rice Yongyou 1540 as material. Quantitative index of population and precise and quantitative cultivation techniques for 850 kg/667 m2 of Yongyou 1540 were summed up in this paper.

Key words: rice, Yongyou 1540, nutrition bowl mechanical transplanting, quantitative index of population, precise and quantitative cultivation technique
