山地早地一般主产杂粮,至于水稻的生产也主要以陆稻为主,产量低下。近年来,人们提出了水稻旱种栽培技术新的设想,并用目前生产潜力较高的杂交水稻,来改革山区传统的水稻生产,提高山区土地的经济效益,同时也提高山区人民的生活水平。然而,水稻在旱种的生态条件下其生长发育将产生何种变化,对于探索水稻旱种的可行性、明确杂交水稻旱种的栽培特点等,迫切需要了解。为此,本试验进行了初步研究。
The main mountainous areas generally produce miscellaneous grains, while rice production is mainly dominated by onshore rice, with low yields. In recent years, people have proposed a new tentative plan for dry cultivation techniques of rice and used the current high-potential hybrid rice to reform the traditional rice production in mountainous areas, improve the economic benefits of mountainous land and raise the living standards of people in mountainous areas. However, what kind of changes will happen to the growth and development of paddy under the ecological conditions of drought-cultivation? It is urgent to understand the feasibility of exploring the dry-farming of rice and the cultivation characteristics of dry-cultivation of hybrid rice. To this end, the pilot conducted a preliminary study.
