旱作水稻的生态环境与淹水栽培时显著不同,所以不能直接应用已有的水稻栽培经验。旱种水稻的历史较短,很多技术问题,有待进一步研究。其中找出适宜的播种期,充分利用当地的光、温资源,是获得旱作水稻稳产高产的一项重要措施。为此,1981年在省农科院内试验田安排了播期试验,1982～1983年与有关单位协作探讨了最佳播期。本文主要以沈阳、海城两点1982～1983年试验资料进行初步总结。
The ecological environment of dryland rice is significantly different from that under flooded cultivation, so the existing rice cultivation experience can not be directly applied. The history of dry cultivation of rice is short, a lot of technical problems, pending further study. One of the important measures is to find suitable sowing date and make full use of local light and temperature resources to obtain stable and high-yield rice in dry land. To this end, in 1981, the experimental field in the Academy of Agricultural Sciences arranged a sowing date test, 1982 ~ 1983 and the relevant units to discuss the best sowing date. In this paper, Shenyang, Haicheng two 1982 ~ 1983 test data for the first time.
