杂交水稻是在英明领袖华主席亲切关怀下成长发展起来的。我县经过几年来试种,也表现了穗大粒多、分蘖力强、适应性广的丰产性能。我站通过对杂交水稻各生育期对温度要求的观测,并根据山区气候特点,分析了我县不同海拨高度杂交水稻的布局。一、杂交水稻种植的气象条件农作物与气象条件之间的关系,主要表现在对水份、光照和温度的要求。我县东临沿海,境内森林密布,年雨量大,水稻所需水份一般都能充分满足。而光照和温度的变化对农作物生长影响较大。其中,低温冷害是对我县粮食生产威胁最大的自然灾害。这里主要分析杂交水稻各生育阶段对气温的要求。
Hybrid rice grew up under the gracious care of Chairman Hua, the wise leader. After several years of county trial, but also showed the spike large grain, strong tillering ability, wide adaptability of the high performance. Based on the observation of the temperature requirement during the growth period of hybrid rice and based on the characteristics of the mountainous climate, I analyzed the layout of different altitude hybrid rice in our county. First, the hybrid rice cultivation meteorological conditions Crops and the relationship between the weather conditions, mainly in the water, light and temperature requirements. My county east coast, the territory of dense forests, annual rainfall, the water required for rice in general can fully meet. The light and temperature changes have a greater impact on crop growth. Among them, chilling damage is the most serious natural disasters in our county grain production. Here mainly analyzes the hybrid rice growth stages of the temperature requirements.
