我县回龙山区从1983年开始大面积推广杂交晚稻。1984年杂交晚稻推广面积为1.3万亩,占整个晚稻面积43.3%,增强了晚稻生产力,实现了晚稻超早稻,获全年粮食丰收。但据调查的情况表明:杂交晚稻的产量很不平衡,去年高产户中平均亩产1,230斤,低产户平均亩产620斤。全区最高亩产量已达1,427斤,最低产量仅450斤。明显地表现为高而不稳。因此,杂交晚稻的生产潜力仍然很大,我们总结高产田块的栽培技术,找出低产田低产的原因,摸索出了一套合理的栽培技术。
Huilongshan District, I started in 1983 to promote hybrid rice late rice. 1984 hybrid late rice to promote an area of 1.3 hectares, accounting for 43.3% of the entire late rice, enhance late rice productivity, to achieve a late rice late rice, won the full-year grain harvest. However, according to the survey, the output of late hybrid rice is very uneven. Last year, the average yield per mu of high-yielding households was 1,230 kg and that of low-yielding households was 620 kg. The region has reached the highest mu yield 1,427 pounds, the minimum output of only 450 pounds. Obviously high and unstable. Therefore, the potential of hybrid late rice production is still great, we summarize the cultivation techniques of high-yield plots to find out the causes of low-yielding low-yielding fields, worked out a set of reasonable cultivation techniques.
