我区水稻生产年际间波动很大,除与栽培条件、品种、病虫等有关外,受各年气象条件的影响是很大的。1982年我区早、晚稻获得较大幅度增产,与气象条件有一定的关系。本文主要分析该年早晚稻生产中的有利与不利气象条件以及它们对增产所起的作用。 一、早稻增产的气象条件分析 根据我站几年来田间试验,人工气候箱模拟试验及调查收集早稻社会产量与相应的气象资料进行统计分析,初步得出影响我区早稻产量的主要气象因子为:1.营养生长期
The annual variation of paddy production in our region fluctuates greatly. Except for the conditions of cultivation, varieties, pests and diseases, the annual impact of meteorological conditions is very great. In 1982, the early and late rice crops in our district got a more substantial increase in yield, which has some relations with the meteorological conditions. This paper mainly analyzes the favorable and unfavorable weather conditions in the rice production in the early or late of the year and their role in increasing production. First, the meteorological conditions for early rice yield increase According to my station field experiments in recent years, the artificial climate chamber simulation test and survey to collect early rice social output and the corresponding meteorological data for statistical analysis, initially came to my area early rice yield of the main meteorological factors are: 1. Vegetative growth period
