我省春播期间气候多变,持续的阴雨低温,常严重威胁着早稻秧苗的生长。六十年代初,继普及湿润育秧之后,大力推广塑膜覆盖育秧,对发展双季稻生产起了很大的促进作用。1974年又从趸秧基础上发展为温室秧以至温室无土育秧,以其播种量大,育秧期短,成苗率高,不用秧田,适于机插,受到群众欢迎。1977年全省早稻插无土秧500万亩,约占早稻面积30％以上。然而,这一年遇到4月27日到5月10日的长期阴雨低温,无土秧早稻普遍发生僵苗滞长,产量不
Climate change during spring in our province, continued overcast rain and low temperature, often a serious threat to the growth of early rice seedlings. In the early sixties, following the popularization of wet seedling, vigorously promote the plastic film covered seedling cultivation, the development of double cropping rice played a significant role in promoting. In 1974 from the basis of the development of the single-seedlings and greenhouses to greenhouse greenhouse seedlings, with its large seeding, seedling short, high seedling rate, without seedling, suitable for machine inserted by the masses. In 1977 the province’s early rice inserted without soil seedlings 5000000 mus, accounting for about 30% of the area of early rice. However, this year encountered April 27 to May 10 long-term overcast rainy and low temperature, soilless seedling early rice generally stagnant and stagnant, yield is not
