我省自从推广水稻秧苗带土移栽以来,早稻的烂秧现象固然有了减轻,但死苗情况每年仍有不同程度的发生,严重时也会造成秧苗大量死亡。1972年,嘉兴地区早稻育秧期间普遍发生了死苗,有的社队受害严重。据在嘉兴县东栅公社调查,全社94个生产队,几乎队队都发生死苗,严重的田块,死苗率达70%以上,致使有些队造成了缺秧或推迟了插秧季节,使早稻生产受到了一定损失。为了弄清这次大面积死苗的原因及其防治措施,我们在东栅公社作了调查研究,现将有关资料整理如下,以供参考。
Since the introduction of soil transplanting of rice seedlings in our province, the phenomenon of rotting seedlings in early rice has been alleviated. However, the occurrence of dead seedlings is still varying from year to year. In severe cases, large numbers of seedlings will also be killed. In 1972, there was a general incidence of dead seedlings during early rice seedling growing in Jiaxing, and some of the commune teams suffered serious injuries. According to the investigation in Jiaxing County Dongzha commune, the whole community 94 production teams, almost all teams have dead seedlings, severe plots, dead seedlings rate of 70% or more, resulting in some teams caused by the lack of seedling or postponed the season of planting, so that Early rice production has suffered some losses. In order to find out the reasons for this large area of dead seedlings and their prevention and treatment measures, we conducted a survey in Dongzha commune, the relevant information is now organized as follows for reference.
