“翻秋留种”是直生型春植花生全苗增产的有效措施,但是,各地多数为留种而种植秋花生,每因它的面积少,不把它当作一造来抓,种植与管理均较粗放,造成向来低产,且种子饱满度也普遍低于春植,使之长期存在秋植种子出苗虽较齐快,而普遍不及春植种子出苗健壮。 然而,从广东秋季光温条件来看,秋花生产量不应亚于春植;尤其中至南部地区,秋季光温条件特别优异,秋花生产量应高于春植。就台山地区近二十二年平均气温和光照来说:秋植花生苗期在8月份,平均气温在27.4℃,有利于早生快长;中期在9至10月、平均气温24℃,且
“Turned autumn planting” is a straight-type spring planting peanut seedlings yield an effective measure, however, most of the rest for planting seeds and planting autumn peanuts, because of its small area, do not treat it as a scratch, planting And management are more extensive, resulting in always low yield, and the plumpness of the seeds is also generally lower than that of spring planting, making the long-standing autumn planting seed emergence though relatively quick, but generally less than spring planting seedling robust. However, from the perspective of Guangdong’s autumn light and temperature, the yield of autumn flowers should not be less than that of spring planting; especially in the middle and south areas, the light and temperature conditions in autumn are particularly excellent, and the yield of autumn flowers should be higher than that of spring planting. As far as the average temperature and light of Taishan in the past 22 years are concerned, the average temperature of autumn planting peanut in August is 27.4 ℃, which is good for early growth and long life. In mid-September to October, the average temperature is 24 ℃
