烂秧是长期以来影响水稻增产的一个重要问题。特别是在提早播种的情况下更易发现,如1951、1953、1955、1960和1965年在江西有很多地区早稻发生了烂秧,而在1961年并有较严重的晚稻烂秧现象。这不仅造成种谷的大量损失,而且因进行补种延迟了插秧与成熟期,影响产量,因此,防止烂秧,是保证秧苗生长健壮争取水稻增产的重要措施。近年来,对烂秧的原因及其防止措施,我们曾在生产实践中作过多次的调查和试验研究工作,分析的结果,简介如下,以供参考。
Rotten transplanting is an important issue that has long affected rice yield. Especially in the case of early sowing more easily found, such as 1951, 1953, 1955, 1960 and 1965 in many parts of Jiangxi have rotten seedlings early rice, and in 1961 and there is more serious late rice rot seedling phenomenon. This not only caused a large loss of seed valley, but also delayed seedling and maturity due to re-planting. Therefore, preventing rotting seedlings is an important measure to ensure the robust growth of seedlings for rice yield increase. In recent years, the reasons for rotten seedlings and prevention measures, we have done in the production practice of many investigations and experimental studies, the analysis of the results are as follows, for reference.
