永康市杂交晚稻种植面积大,约占整个晚稻面积的95%左右,“双夏”季节紧,任务重,劳动力紧张,加之夏季高温,杂交晚稻插后易败苗,影响返青、分蘖,常导致产量不高。为此,我们根据早稻抛秧和早育秧能显著提高秧苗素质,增加产量的经验,对杂交晚稻旱育抛秧进行了有益尝试。据大区比较试验,塑盘旱育抛秧比常规手插秧每亩增产20.07公斤,再加节省秧田和人工,可净增经济效益74.50元。现将有关经验介绍如下:1.培育塑盘旱育壮秧(1)秧盘选用根据杂交晚稻秧龄长的特点,我们对原塑盘进行改造,
The hybrid rice planted in Yongkang City has a large acreage, accounting for about 95% of the whole late rice area. Due to the tight season, heavy task and labor shortage, combined with summer heat, Yield is not high. To this end, we based on early rice throwing and early seedling can significantly improve the quality of seedlings, increase the yield of experience, hybrid late rice dry throwing Yang made a useful attempt. According to the comparative test of the large area, the plastic tray throwing seedlings raised 20.07 kg per acre compared with the conventional hand transplanted seedlings, adding savings of seedlings and labor, which could increase net profit by 74.50 yuan. The relevant experience is introduced as follows: 1. Cultivation of plastic plate drought nurturing strong seedlings (1) Selection of seedlings According to the characteristics of hybrid late rice seedling age, we transform the original plastic plate,
