摘要
通过对淮稻9号超高产栽培技术试验研究,明确了淮稻9号在江苏里下河稻区获得稳定700 kg/667 m2以上产量的最佳播种期为5月5~10日,肥床旱育栽插基本苗1.9万株/667 m2,行距以26.7㎝最佳,氮肥施用量20~22 kg/667 m2,水稻生育前期基蘖肥与穗肥的施比例为(5.5~6.0):(4.0~4.5)。
Through super high-yielding cultivation technique for Huaidao 9, the technique parameters to realize 700 kg/ 667 m^2 for Huaidao 9 in Lixiahe area, Jiangsu are suggested that the optimum sowing dates are May 5 to 10, basal seedling density on bed is 19 000/667 m2, distance between the rows is 26.7 cm, nitrogen application amount is 20 to 22 kg/667 m^2 and the ratio of basal fertilizer to panicle fertilizer is (5.5-6.0): (4.0-4.5).
