几年前全县早稻坐苗面积达18%,水稻坐苗,轻者减产3—5成,重者颗粒无收,对这一问题,我们查明了水稻坐苗的主要原因,采取了针对性的措施。经过四年来的推广应用,早稻坐苗面积已降到占总面积的9.4%,因此每年增产粮食70万斤以上。本文主要探讨由生理病害引起水稻坐苗的主要原因和可能机理,以及我县水稻坐苗的主要类型和治理措施。
A few years ago, the area occupied 18% of the early rice planting area, rice planting seedling and light yield reduction of 3-5%. In this problem, we identified the main reason for planting rice seedling, Sexual measures. After four years of popularization and application, the area of early rice planting and sitting has dropped to 9.4% of the total area, thus increasing the output of grain by more than 700,000 kg each year. This article mainly discusses the main reason and possible mechanism of rice seedlings caused by physiological diseases, and the main types and control measures of rice seedling in our county.
