正三十烷醇是一种新型的植物激素,本刊曾与去年十二期上作了比较详细的介绍。这次对我省杭州大学生物系等单位于去年在水稻、油菜、茶叶、络麻等作物上进行试验应用的情况作一报道。在水稻上的应用:杭州大学生物系以“原丰早”作试验材料,在抽穗期和扬花期均喷洒0.1ppm的正三十烷醇。结果处理的和对照的亩产分别为702斤和666斤,增产5.4％。结实率分别为81.8％和78.8％,千粒重分别为22克和21.2克。以“杂福一号”为材料,在孕穗期和扬花期每亩喷洒120斤0.5ppm的正三十烷醇,增产13.7～14.8％。以矮梗23作材料,在盛花期喷洒0.5ppm正三
Is triacontanol is a new type of plant hormones, the magazine has made a more detailed introduction on the 12th last year. This time, I made a report on the experimental application of such items as rice, rape, tea, narcotics and other crops to the department of biology of Hangzhou University in our province last year. Application on rice: Department of Biology, Hangzhou University, “Haramatsu early” as the test material, both heading and flowering are spraying 0.1ppm n-triacontanol. The results of the treatment and control of the mu were 702 pounds and 666 pounds, an increase of 5.4%. Seed setting rates were 81.8% and 78.8%, respectively, and grain weights were 22 and 21.2 grams, respectively. With “He Fu No.1” as the material, 120 kg of 0.5ppm n-triacontanol was sprayed at the booting and flowering stages and the yield was increased by 13.7-14.8%. To short stalk 23 for the material, spraying 0.5ppm at full bloom is three
