一、水稻的生态环境云南水稻的生态环境,从100米的低热河谷,到2700米的高山盆地,不仅品种类型丰富多彩,稻田的地势、气候也特别复杂。在低纬高原,少冬少暑,明显区分干季和雨季的气候条件下,海拔1500米左右的稻区一般较为高产稳产;由此上下三至四百米以外,水稻单产则趋低而不稳。全省稻区由于冬春风多风大(西南风)干旱缺雨,在低热地区历史上无论水稻、陆稻都以一季晚熟中稻或晚稻为主,因为这样才能避过多雨季节成熟,进入干季才便于收获。但是病、虫、草害不仅不可避免,还会
First, the ecological environment of rice Yunnan rice ecological environment, from 100 meters of low thermal valley, 2700 meters of alpine basin, not only the variety of types of colorful, paddy topography, the climate is also particularly complex. In the low latitude plateau, less winter and less summer, obviously distinguish between dry season and rainy season conditions, the rice paddy area of about 1,500 meters above sea level is generally more stable and high yield; from top to bottom outside the three to four hundred meters, rice yield is lower and not stable. Due to the drought and windy (southwesterly) aridity and lack of rainfall in the rice growing areas in the province, both rice and paddy rice in the history of low-temperature areas are dominated by late-season mid-season rice or late-season rice, because they can avoid the rainy season and enter the dry season It is easy to harvest. But disease, insects, grass damage is not only inevitable, but also
