矮丰2号是库尔勒垦区和塔里木垦区水稻的主栽品种,种植面积占水稻面积的90％以上,种植方式为直播栽培。为了探索矮丰2号的生育规律,我们从1972年以来研究了其分蘖规律和叶片出生与分蘖、穗分化、节间伸长的同伸关系及相应的肥水效应,确定了按叶龄进程进行丰产栽培的促控原则。生产实践证明这个原则是正确的。 Aphrodite 2 is the main cultivated rice in Korla reclamation area and Tarim reclamation area, covering more than 90% of the rice area. The cultivation method is direct seeding cultivation. In order to explore the fertility rule of Aphrodite No.2, we studied its tillering rule and the relationship of isobaric extension and tillering, spike differentiation and internode elongation and corresponding fertilizer and water effect since 1972, Promote the principle of high yield cultivation. Production practice has proved that this principle is correct.
