掌握水稻产生空秕及产量变化的气候规律,减少或克服水稻生育后期的低温影响,是提高水稻产量的重要条件。本文以昆明地区水稻生产实践,试验研究结果及气候变化规律,就低温的影响与水稻空秕及产量变化的关系,进行农业气象分析。一、昆明地区水稻产量变化规律: 广大农民群众在水稻生产实践中,为创造水稻的高产积累了丰富的经验,在水稻栽培上广泛流传的“立夏栽秧产量高,小满栽秧压断腰,芒种栽秧难增产,夏至栽秧轻飘飘”的农谚,是群众掌握气候变化的规律,为获得水稻稳产高产的科学总结。根据我站
It is an important condition to improve the yield of rice by grasping the climatic rule of rice yield and yield changes, reducing or overcoming the low temperature influence during late growth period of rice. In this paper, based on the practice of rice production, experimental results and climate change in Kunming, the agrometeorological analysis was conducted on the relationship between the effects of low temperature and the changes of rice straw and yield. First, the variation of rice yield in Kunming: The majority of peasants in the rice production practice, to create high-yielding rice has accumulated rich experience in rice cultivation widely circulated "early summer planted seedling production is high, It is a scientific summary that the masses should master the climate change and obtain a stable and high-yielding paddy rice.
