花生收获过早,由于生育期短,积温不足,至叶的养分未及向荚果运转,多数荚果尚未充分成熟,因而产量降低,出油率也低。据试验,每早收1天,每亩减产3.0～7.3斤花生。收获过晚,则由于微生物侵染和打破种子休眠等原因,造成荚果生芽,种子变质腐烂,丧失经济价值,而且落地果多,难于收净,茎枯叶落,利用价值降低。所以,掌握好地膜花生的收获适期,是实现高产优质的重要措施。 Peanuts harvest too early, due to short growth period, lack of accumulated temperature, the nutrients to the leaves did not move to the pods, the majority of pods have not yet fully mature, and thus reduce the yield, the oil yield is also low. According to the test, every morning for 1 day, yield reduction of 3.0 ~ 7.3 kg per acre peanut. Harvesting too late, due to microbial infection and to break the seed dormancy and other reasons, resulting in pod germination, seed spoilage, loss of economic value, and the ground fruit and more difficult to close the net, dead stem leaves, the use of lower value. Therefore, a good grasp of plastic film peanut harvest is an important measure to achieve high yield and quality.
