地方品种特性及其栽培技术的形成与自然气候特点、生产力发展水平等均有一定的关系。认真总结群众在生产实践中积累的这些经验,对新品种的选育、栽培技术的改进,甚至整个耕作制度的改革均具有重要的现实意义。为此,我们仅从农业气象角度作一初步分析,供生产和进一步研究的参考。 The formation of local variety traits and cultivation techniques has some relations with the natural climate characteristics and the level of productivity development. It is of great practical significance to conscientiously sum up these experiences accumulated by the masses in their production practices and to carry out the breeding of new varieties, the improvement of cultivation techniques, and even the reform of the entire farming system. For this reason, we make a preliminary analysis from the perspective of agricultural meteorology for reference for production and further research.
