花生原产热带,生长发育要求较高的温度。温度偏低或昼夜温差较大,都会使开花过程延缓以至停顿,影响受精。因此,我省花生产区主要分布在南部和海拔1300米以下的地区,大致和双季稻分布区域相同。为了加速山原红壤的改良,充分利用土地资源,增加农民收入,在“覆盖农业”的思想指导下,我们在海拔1900米左右的陆良和昆明等地进行了地膜覆盖栽培花生的试验研究。鉴于花生是一种喜热、怕涝、耐瘠的豆科作物,最好作畦种植,以免渍水并利于增温。试验区密度每亩7500塘左右,每塘两
Native tropical peanut, growth and development of higher temperatures. Low temperature or large temperature difference between day and night, will delay the flowering process until pause, affecting fertilization. Therefore, the flower production area of our province is mainly distributed in the south and the area below 1,300 meters above sea level, which is roughly the same as that of the double cropping rice. In order to accelerate the improvement of the mountainous red soil, make full use of the land resources and increase the farmers’ income, under the guidance of the thought of “covering agriculture”, we carried out the experimental research on mulching and mulching peanut cultivation at Luliang and Kunming, about 1,900 meters above sea level. In view of peanuts is a kind of hi heat, fear of waterlogging, barren bean crops, the best planted planting, in order to avoid waterlogging and conducive to warming. Test area density 7500 ponds per mu, two per pond
