水稻是我县的主要粮食作物,常年播种面积在79万亩左右,为进一步提高水稻总产,我县在大力发展杂交晚稻的同时推广了杂交早稻。由于本地常年早稻播种育秧期间,寒潮频繁,气温较低,阴雨天多,对杂交早稻露地育秧十分不利,播种后烂芽死苗严重,成秧率低,用种量大。为了克服杂交早稻的这一缺点,充分发挥杂交早稻的高产优势,我县自1989年开始推广了地膜低拱育小苗移栽。杂交早稻采用育小苗移栽,具有播种早、成秧率高;移
Rice is my county’s main food crops, perennial planting area of about 790000 acres, in order to further improve the total output of rice, my county in the development of hybrid late rice at the same time promote the hybrid early rice. As the local perennial early rice during sowing seedlings, cold frequent, low temperature, cloudy and rainy day, early hybrid rice seedling planting is very unfavorable, sowing buds after sowing serious, low rate of planting seedlings with large seeds. In order to overcome this shortcoming of hybrid early rice and give full play to the advantages of high yield of hybrid early rice, my county since 1989 to promote the cultivation of low arch seedlings transplanting. Hybrid early rice transplanting with seedlings, with sowing early, into a high rate of transplanting;
