大理县地处高原,水稻生产常受低温冷害的危害,造成产量不稳定。我站在县委的领导下,与农村四级科技网配合,对水稻低温冷害指标、予报方法和防御措施进行了多年的研究,特别七六、七七年的研究获得了较好的成果。一、大理县低温冷害对水稻产量的影响及其指标大理县雨热同季的气候特点与水稻喜温喜湿的特性配合一致是水稻高产稳产的气候基础;“两头低温影响,中间高温不足”又是水稻产量不稳的气候原因。因此,如何防御两头低温的危害,充分用上
Dali County is located in the plateau, rice production is often affected by cold damage, resulting in unstable output. I stood under the leadership of the county Party Committee and cooperated with the Rural Science and Technology Network to conduct research on indicators of low temperature chilling injury, reporting methods and defensive measures for rice for many years. In particular, the researches in 1976 and 1977 achieved good results. First, Dali County, chilling injury on rice yield and its indicators Dali County, rainy season with the climatic characteristics and the characteristics of rice Xihuoxing consistent with the high and stable rice paddy climate base; “two low-temperature impact, the lack of intermediate temperature” It is also a climatic reason for unstable rice production. Therefore, how to prevent the two low-temperature hazards, full use
