三十烷醇是一种新型的植物生长促进剂。它能促进花芽分化,提高结实率,提高光合强度,促进水分、矿物质营养的吸收,从而有利于物质积累和植物生长。对蔬菜和各种农作物有促进生长、增加产量的效果。兰州市对三十烷醇的推广应用开展不久,从1983年开始在大白菜、黄瓜,莴荀等蔬菜品种上进行不同浓度处理试验。1984年,我们为了明确莲花菜叶面喷洒三十烷醇的增产效果及最佳浓度,进行了不同浓度的处理试验。一、材料和方法 1.药剂:本试验所用三十烷醇,为厦门大学化工厂生产,晶体。 2.试验品种:晚丰甘蓝。 3.试验地:试验地设在大雁滩四队,前茬作物为大白菜。高垄栽培,垄高10厘米,垄
Triacontanol is a new plant growth promoter. It can promote flower bud differentiation, improve seed setting rate, increase photosynthetic intensity, and promote the absorption of moisture and mineral nutrition, which is good for material accumulation and plant growth. On vegetables and various crops have to promote growth, increase the yield effect. Lanzhou City, on the popularization and application of triacontanol started soon, beginning in 1983 in cabbage, cucumber, lettuce and other vegetable varieties of different concentrations of treatment experiments. In 1984, in order to clarify the lotus leaf foliar spraying triacontanol production and the best concentration, different concentrations of the treatment test. First, materials and methods 1. Pharmacy: Triacontanol used in this experiment, Xiamen University chemical plant production, crystal. 2. Test varieties: late abundance of cabbage. 3. Test place: experimental site located in Dayan Beach four teams, the former crop of Chinese cabbage. Ridge cultivation, ridge height 10 cm, ridge
