1981、82两年,我社科技站和联合大队试验和推广了早稻两段育秧。81年占全大队早稻面积的40％,82年占60％。两年来,联合大队的早稻亩产都超过了850斤,名列全社第一,比公社平均亩产增长18％左右。两段育秧的好处是:第一秧苗健壮。早春采用塑料薄膜覆盖密播小秧田,出苗率高,生长快,冻害轻,3叶期移入寄秧田。可以改善秧苗的生长环境,一般苗高25厘米左右,绿叶4张以上,分蘖率在80％左右,移栽后活棵早。第二增粒增重。由于 In 1981 and 1982, CCS station and joint brigade experimented with and popularized the two-stage seedling growing of early rice. 81 years accounted for 40% of the entire brigade area of ​​early rice, 82 accounted for 60%. Over the past two years, the joint brigade has gained more than 850 kilograms of harvested early rice per mu, ranking first in the whole community and about 18% more than the average commune per mu. The benefits of two sections of seedlings are: the first seedling robust. Early spring plastic film covered intimate small seedling field, the emergence rate is high, fast growth, frost damage light, 3 leaf stage into the seedling. Can improve the growth environment of seedlings, generally about 25 cm high, more than 4 green leaves, tillering rate of about 80%, live early after transplanting. The second grain weight gain. due to
