错开移栽期是延长采收时间最有效的方法.1976试验表明不同的施氮率和采收速率作用很小,但其它年份中可影响采收始止时间0.5～1周.乙烯利的处理对缩短采收期颇有希望,但随之而来与它应用的其它相关因素提出了是否合适的问题,更好地利用现有设备和资源以降低生产成本的管理措施也在进展;然而,在具体实现前,需要通过田间测试.
The most effective method to prolong the harvesting time is to stagger the transplanting period.176 Experiments show that the effects of different rates of nitrogen application and harvesting rate are very small, but in other years, the harvesting start time can be affected from 0.5 to 1 week. Promising to shorten the period of harvesting, but the ensuing associated with other factors it applied raised the question of whether the appropriate problems, and management measures to make better use of existing equipment and resources to reduce production costs are also progressing; however, In the concrete realization of the need to pass the field test.
