水稻稳产高产是由品种、栽培技术、气象条件等三大基本因素所构成的。水稻单产的变化幅度决定于这些因素的变化情况和相互协调的程度。我县历年的水稻单产的变化幅度较大,产量不稳不高。因此,探讨影响我县水稻产量的主要因素,并进行相关性测定,将对我县水稻品种搭配提供一些理论依据。
Steady and high yield of rice is composed of three basic factors: variety, cultivation technology and meteorological conditions. The magnitude of the change in rice yields is determined by the changes in these factors and the degree of mutual coordination. In the past years, the yield of paddy per unit area in our county has been greatly changed, and the output is not stable. Therefore, to explore the main factors affecting the yield of rice in our county, and to determine the relevance of rice varieties in our county will provide some theoretical basis.
