我场开展红麻短光照制种试验,1976年初步获得成功。1977年又进一步进行了不同叶令遮光试验、遮光处理后打顶抹叉增产效果及不同天数遮光处理对坐果的影响等11项试验,取得了显著效果。试验证明,红麻短光照处理制种,是解决北方红麻留种问题的有效办法。1977年红麻短光照制种试验苗床面积200平方米,其中收到种子的120平方米,共收种子15.2斤,平均折合亩产86.7斤,最高的折合亩产484.6斤。现将试验结果简述为下。
My field to carry out kenaf short light species test, initial success in 1976. In 1977, further experiments were carried out on 11 tests such as different leaf-shielded test, the effect of top-hatching and shaving after shading treatment and the effect of different days of shading treatment on fruit setting, and achieved remarkable results. Experiments show that kenaf short light treatment seed production is to solve the problem of kenaf remaining species in the North effective way. In 1977, kenaf short-light illumination test seedbed area of 200 square meters, of which received 120 square meters of seeds, received a total of 15.2 pounds of seeds, the average yield of 86.7 kg per mu, the highest yield of 484.6 kg per mu. Now the test results as follows.
