1980年黑龙江省从日本引进了一套水稻机械设备和物资,在学习日本育苗技术的基础上,密切结合我省水稻生产实际,选定在五常县第三良种场进行水稻机械化塑料大棚秧盘育中苗技术的试验研究。试验用M—18型塑料大棚五套,4月10日开始播种,4月19日播完,共育苗4,965盘。基本上育成了壮苗。5月20日插秧,5月26日插完,共机插150亩。插后返青快,分蘖早,加以合理培管,平均亩产1,052斤,其中64.8亩早锦品种,亩产达1,080.2斤,比当地邻近高产生产大队(采用一般育苗方法)平均每亩增产350—450斤,增产50—75％。现将育苗技术简介如下:
In 1980, Heilongjiang Province imported a set of rice machinery equipment and materials from Japan. Based on the study of Japan’s seedling technology and the practice of rice production in our province, Heilongjiang Province decided to conduct the cultivation of rice mechanized plastic shed in the third seed farm in Wuchang County Experimental Study on Zhongmiao Technology. Test with five sets of M-18-type plastic shed, sown on April 10, sown on April 19, a total of 4,965 dishes. Basically bred strong seedlings. May 20 planting, inserted on May 26, a total of 150 acres of plug-in. The average yield per mu is 1,052 kg, of which 64.8 mu is the early broccoli variety with a yield of 1,080.2 kg. Compared with the local high yielding production brigade (using the general breeding method), the average yield per mu is 350- 450 pounds, an increase of 50-75%. Breeding techniques now as follows:
