编辑同志: 去年我们在本刊第7期发表了《红麻矮化薄膜育种》一文后,为进一步提高完善此项技术,当年又设计了一些试验,发现有以下几个方面必须注意的问题。这些问题如果掌握不好或错过时机,就会导致失败,前功尽弃。一、床土以沙壤土和沙土较好,粘土因通透性差插梢成活率低。据试验,沙土地成活率为90.5％,沙壤土成活率87％,而粘土地只成活65％。
Editor’s Comrade: Last year we published in the seventh issue of this article, “Kenaf dwarf film breeding,” a text, in order to further improve and perfect the technology, then designed a number of tests and found the following aspects must pay attention to. If these problems are not well managed or miss the opportunity, they will fail and will come to naught. First, bed soil to sandy loam and sandy soil is better, clay because of poor permeability, poor survival rate. According to the test, the survival rate of sandy land is 90.5%, sandy loam survival rate is 87%, while that of clay is only 65%.
