The field and pot experiments were conducted to study the effect of the allocating ratio of N-fertilizer on nitrogen uptake, grain amino acid contents and grain yield of two-line hybrid rice.

The width of seedling stem,the tillering rate, the number of tillers, the number of ears and the grain yield were increased by 6.

Using two-line hybrid rice Peizashanqing and three-line hybrid rice Shanyou 63 as the materials, the effects of nitrogen and potassium at initial heading stage on photosynthetic rate of flag leaf and grain yield were studied by way of pot culture with four treatments, i.

It can only be guaranteed a high-efficient, sustained development of rice production from pursuing the single goal of high yield to pur.
