我场栽培水稻二十多年,在大面积机械化栽培方面积累了一些经验,由原来人工水播发展成大面积机械旱直播,产量由亩产250斤提高到450多斤。但因近年连续低温干旱,春季严重枯水,水稻播后不能及时灌水,既影响水稻正常生长发育,延迟生育期,造成贪青晚熟,又因灌水不及时,压不住草,造成草荒,影响产量,成为发展水稻生产的一个突出矛盾。为了解决这个问题,1977年我场四连提出了“水稻地下播种苗期旱长”的栽培方法,在严重干旱低温的1977年,930亩水稻获得亩产527斤的好收成。
My field of cultivation of rice for more than 20 years, in a large area of mechanized cultivation has accumulated some experience, from the original artificial water development into large areas of mechanical drought direct seeding, yield increased from 250 kg to 450 kg per mu. However, due to the continuous low temperature and drought in recent years, severe dry spring in spring, the rice can not be timely after sowing, not only affects the normal growth and development of rice, delayed growth period, resulting in late blooming, and irrigation is not timely, Production has become a prominent contradiction in the development of rice production. In order to solve this problem, in 1977, our company repeatedly proposed the cultivation method of “Drying Rice Seedlings Sowing Droughts at Seedling Stage”. In 1977, 930 mu of rice received a good yield of 527 kg per mu in severe drought and low temperature.
