水稻品种的光温生态特性是高产栽培的理论基础。不同的水稻生态类型具有不同的光温生态特性,有其不同的地哩、季节适应性。而生态环境又对水稻品种的生长发育产生直接影响。研究各类水稻品种的光温反应特性,则为水稻引种、新品种选育、耕作制改革和制定栽培技术等提供理论依据。近两年来,我们对水稻品种的光温生态特性作了初步研究,其试验情况如下:
The light and temperature ecological characteristics of rice varieties are the theoretical basis of high-yielding cultivation. Different rice ecological types have different light and temperature ecological characteristics, and have different degrees of adaptability to the season. The ecological environment has a direct impact on the growth and development of rice varieties. Studying the light and temperature response characteristics of all kinds of rice varieties provides the theoretical basis for introduction of rice, selection of new varieties, reform of farming system and cultivation techniques. In the past two years, we conducted a preliminary study on the light and temperature ecological characteristics of rice varieties. The experimental conditions are as follows:
