杂交棉制种是一种劳动相对密集型的生产活动,尤其在授粉季节,时间紧、用工多、工时长、劳动强度大。加之这几年的气候不利影响,劳动力缺乏,棉花制种产量一直较低,制种用户、生产企业效益下降。怎样利用现有的资源,提高棉花杂交制种产量,降低生产成本,进而提高经济效益。根据近几年的制 Hybrid cotton seed production is a relatively labor-intensive production activities, especially in the pollination season, time is tight, more labor, long working hours, labor-intensive. Coupled with the adverse effects of the past few years of the climate, the lack of labor, cotton seed production has been low, seed users, manufacturers benefit decreased. How to make use of the existing resources, increase the yield of hybrid cotton seed production, reduce the production cost and further improve the economic benefits. According to the system in recent years
