“六氯苯”对於水稻杀虫力的良好作用,从各地水稻生产和试验中都得到证明;因为“六氯苯”含有一定量对植物有害的丁體,如据葉曉霞同志“六氯苯损害水稻幼根观察”的报告,幼苗期施用不当反致严重抑制水稻幼根的生长发育。 1956年我们试验发现,在水稻不同生育阶段和不同秈、粳類型品种施用同量“六氯苯”也有不同反应,这对我们在研究“六氯苯”作为水稻内吸杀虫剂时从“六氯苯”与水稻生理的研究上提出了新的课题。试验是在1956年秋季本站试验埸地上进行,供试品种秈稻为“晚成”,粳稻为“背晚”,施药
The good effect of “hexachlorobenzene” on the insecticidal power of rice has been proved in various rice production and experiments. Because “hexachlorobenzene” contains a certain amount of harmful plants, according to Comrade Ye Xiaoxia, “Hexachlorobenzene Damage to rice seedling observation ”report, the improper application of seedling stage serious inhibition of rice root growth and development. In our experiment in 1956, we found that the same amount of “hexachlorobenzene” was applied at different growth stages and different varieties of indica and japonica at different stages of rice growth. This is the reason that we studied “hexachlorobenzene” as an insecticide in rice from “ Hexachlorobenzene ”and rice physiology research put forward a new topic. The experiment was carried out on the ground of the test station in the autumn of 1956. The indica rice varieties were “late blooming” and the japonica rice was “dorsal and evening”
