1989年以来,洪湖市沙口镇围绕科技兴粮,建设“吨粮工程”,示范、推广汕优63一种双收(即蓄再生稻)高产栽培技术,取得了成功的经验。五年累计推广种植1400多公顷,增收稻谷525万千克。汕优63一种双收高产的理想穗粒结构是:头季稻有效穗667平方米20万,每穗实粒115粒,结实率85％,千粒重28.5克,667平方米产量655千克;再生稻分别为30万、44粒、80％、27克和365千克。高产的配套技术如下: 1.适时播种,确保再生稻安全齐穗 根据我镇近五
Since 1989, Shakou Town, Honghu City, around the science and technology revitalization of grain, building “tons of grain project” to demonstrate and promote Shanyou 63 a double income (that is, regenerative rice) high-yielding cultivation techniques and achieved successful experience. In the past five years, a total of more than 1,400 hectares of cultivated land have been planted, with an increase of 5.25 million kilograms of paddy. Shanyou 63 A double crop yield of the ideal ear grain structure is: the first crop of effective panicle 667 square meters of 200,000, 115 grains per ear solid, 85% seed set, grain weight 28.5 grams, 667 square meters yield of 655 kilograms; regeneration Rice is 300,000, 44, 80%, 27 and 365 kg, respectively. High-yielding supporting technology is as follows: 1. timely sowing, to ensure safe and full of ratoon rice According to my town nearly five
