花生收获过早,籽仁灌浆不足,秕果多,出仁率低,含油量下降;收获过晚,饱果易脱落,腐烂粒增多,造成减产。做种用的花生收获过晚,甚至会丧失生活力,降低发芽率;早熟品种收获过晚,因休眠期短,在土壤水分和温度适宜时,还会造成大量发芽。 Peanut premature harvest, lack of filling seed, fruit and more nuts, kernel rate is low, oil content decreased; harvest too late, full of fruit fall off easily, increased rotten grains, resulting in reduced production. Peanuts do planting too late harvest, and even lose their viability and reduce germination rate; early maturing varieties harvest late, due to the short dormancy, when the soil moisture and temperature appropriate, but also cause a lot of germination.
