种植连作稻,已成为当前浙江省增产粮食的重要措施。但因连作晚稻多采用原单季晚稻或间作晚稻品种,为弥补本田营养生长期的不足,一般采用稀播延长秧龄的办法,因此占用了较多的秧田,减少了早稻面积,影响了全年总产量的提高。同时,稀播长秧龄拔秧也比较困难,这对人少田多、夏收夏种劳力比较紧张的地方,在争取季节上尤为不利。由于以上原因,我们特在已往研究的基础上,在相同的秧田、本田比例的前提下,进行连作晚稻壮秧好拔、既不扩大秧田面积又有利于增产的育秧方法试验。现将1963年的试验结果,总结于后。
Planting cropping rice has become an important measure for increasing grain output in Zhejiang Province. However, continuous cropping late rice mostly uses single-season late rice or inter-crop late rice varieties. In order to make up for the lack of HN in vegetative growth stage, the method of extending seedling age by thin seeding is generally adopted, so more seedling is occupied, the area of early rice is reduced, Increase in production. At the same time, thinning seedling long seedling age is also more difficult to pull seedling, which is more people less Tian, summer harvest summer species more labor-intensive places, in the fight for the season is particularly unfavorable. Due to the above reasons, we conducted experiments on the basis of the previous researches and on the same proportion of seedling and Honda to carry out the method of seedling cultivation with good seedling yield even in late rice without expanding the area of seedling and yield increase. Now 1963 test results, summarized later.
