文化大革命以来,我省大力推广了水稻小苗带土移栽这一新技术,在促进粮食增产上起了很大作用。但是在小苗育秧推广过程中也遇到一些新的困难,早稻的死苗问题就是其中之一。据70年对一些典型单位的调查,早稻死苗一般在10—20％之间,严重的达30—50％,如补救不及就造成缺秧,损失更大。 Since the Cultural Revolution, our province has vigorously promoted the new technology of transplanting rice seedlings with soil and played a great role in promoting grain yield. However, there are some new difficulties encountered in the promotion of seedling raising seedlings. The problem of dead seedlings in early rice is one of them. According to a survey of some typical units in 1970, the stocks of early rice dielings are generally between 10-20% and severely up to 30-50%. If the remedy is not completed, the crops will be lost and losses will be even greater.
