一、试验设计 窄膜植棉,株距12.5厘米,行距(60+40)厘米。 二、田间管理措施 4月15日播种,5月12日定苗,7月18日打顶,9月15日捡头遍花。 三、试验结果 R—1产量最高,较对照增产21.2％。美双抗4号和双基因SGK9708产量较CK增产11.1％、17.3％,品质、抗逆性超过主栽品种,建议示范推广。
First, the experimental design Narrow film cotton, spacing 12.5 cm, row spacing (60 +40) cm. Second, the field management measures April 15 sowing, May 12 Dingmiao, July 18 topping, September 15 to pick the first time flowers. Third, the test results R-1 highest yield, 21.2% increase compared with the control. The yield of double-gene SGK9708 and double-gene SGK9708 was 11.1% and 17.3% higher than that of CK, respectively.
