杂交水稻谷优明占高产栽培技术研究

Techniques for Cultivation of High Yield Hybrid Rice,Guyoumingzhan

  • 摘要: 运用均匀设计, 以杂交水稻谷优明占为材料, 分析不同秧龄、密度和纯N量对产量的影响, 建立产量与3项栽培措施的回归模型。结果表明, 3项措施均对谷优明占的产量有影响。经微机模拟筛选, 秧龄25.429.7d、插植密度30.1万33.2万丛·hm-2、施纯N量183.8210.0kg·hm-2是谷优明占产量达到8 250kg·hm-2以上的高产栽培技术措施。

     

    Abstract: Uniform design was used to analyze the cultivation of the high yield, hybrid rice, Guyoumingzhan, based on three factors:seedling age (X1) , planting density (X2) and quantity of nitrogen (X3) .The regression models for the three factors affecting the rice yield were established.The experimental results revealed that the three factors exerted significant influences on the yield, After a simulated screening and optimization by computer, seedling age in the range of 25.4-29.7dfor transplanting at the density of 301 000-332 000hills·hm-2 with a nitrogen application of 183.8-210.0kg·hm-2 was recommended for the cultivation on yield≥8 250kg·hm-2.
