- 摘要:
- 粮食产量预报已成气象为农业服务的重要手段。利用最新的判断日照时间等科技手段对黑龙江省玉米产量做科学的分析预判,大大加强农业生产提前预判水平。本文从日照时数的光合作用的内在因素入手,分析了光强、温度、水分和二氧化碳4个变量对玉米产量形成过程的影响。全文通过对各种试验的分析,对玉米产量在热量条件满足的前提下产量预报将可获得明显效果。
- Abstract:
- Grain yield prediction has become an important means of meteorological services for agriculture.Using the latest scientific and technological means such as judging sunshine time to make a scientific analysis and prediction of maize yield in Heilongjiang Province,greatly enhancing the advance prediction level of agricultural production.Starting with the intrinsic factors of photosynthesis in sunshine hours,this paper analyzed the effects of light intensity,temperature,water and carbon dioxide on the yield formation process of maize,which resulted in significant differences in dry matter accumulation.On the premise of satisfying the heat condition,the yield forecast will get obvious effect.
