我所自福建三明地区农科所引入杂交中稻汕优63,经两年来的试验示范,一致表明它具有产量高、生育期适中、强抗稻瘟病和容易制种等优点,是适合我省生态条件的较为理想的高产接班种。为了探查汕优63实现大面积高产的规范化栽培技术,我们选取了多个栽培因子,通过正交旋转试验设计,并应用微机模拟寻优,建立初步的数学模型,提供生产上参考和验证。
Since the introduction of hybrid rice Shanyou 63 from Sanming Prefecture Agricultural Science Department, Fujian Province, after two years of trial and demonstration, it has consistently demonstrated that it has the advantages of high yield, moderate growth period, strong resistance to rice blast and easy seed production, Condition of the ideal high-yield successor. In order to explore the standardized cultivation technology of Shanyou 63 to achieve large-area and high-yield, we selected a number of cultivation factors, established the preliminary mathematical model by orthogonal rotation test design and optimized by computer simulation to provide production reference and verification.
