早稻温室无土秧在我县已大面积推广了两年。1976年全县播无土秧5.2万亩,占早稻26万亩的20％,普遍获得了增产。1977年进一步推广到16.2万亩,占早稻31万亩的53％。这项改革,可以说比历次技术推广快而效果显著。但是从两年的情况看,早稻无土秧的亩产量有过800斤的高产片,也有不过四、五百斤的低产田。就是同一品种、同一批秧苗也有产量悬殊较大的情况。如何打破这种不平衡的局面而进一步大面积提高无土秧的产量。这是一个值得认真研究加以总结的问题。我们根据两年的生产实践,体会到要实现这一要求,早稻温室无土秧从育苗到大田栽培管理,下面的一整套技术环节应该引起足够的重视。
Early rice greenhouse soilless seedlings in my county has been widely promoted for two years. In 1976 the county sowed 52,000 mu of soilless seedlings, accounting for 20% of 26 million mu of early rice, and generally gained production. It was further popularized to 162,000 mu in 1977, accounting for 53% of the 31 million mu of early rice. This reform can be said to be faster and more effective than any previous technology promotion. However, from the situation in two years, the mu yield of early rice without soil seedlings has produced 800 kilograms of high-yield film, but there are four or five hundred pounds of low-yield field. Is the same species, the same batch of seedlings also have a great disparity in production. How to break this imbalance and further expand the production of soilless seedlings. This is a question worth serious study to be summed up. According to two years of production practice, we realized that to achieve this requirement, early rice greenhouse soilless seedlings from nursery to field cultivation and management, the following set of technical aspects should cause enough attention.
