三十烷醇[CH_3(CH_2)_(28)CH_2OH]是一种植物生长调节剂.通过多年、多点,不同土壤、季节,不同浓度、喷期、喷次的反复试验及大面积示范结果证明:三十烷醇对各种蔬菜均有一定的早熟、增产效果,一般可提早成熟5～7天,增产幅度在4～43％。通过研究初步确定了适宜喷洒的浓度、时期及喷次和应用方法。浓度:叶菜类适宜0.5ppm,果菜类适宜1.0ppm;喷期:叶菜类较适宜在迅速生长期喷施,果菜类较适宜在初花(果)期喷施;喷次:叶菜类从幼苗生长期至收获前15天內,每隔10天左右连喷2～3次为宜,果菜类从初花(果)期始,每隔10～15天,连喷3～4次为宜。使用三十烷醇的芹菜、大白菜、黄瓜、青椒体內糖、Vc等干物质积累量都有增加;并能减少部分蔬菜病害的发生。
Triacontanol [CH_3 (CH_2) _ (28) CH_2OH] is a plant growth regulator.According to repeated experiments and large-scale demonstration results of years, plots, different soils, seasons, different concentrations, It is proved that triacontanol has some precocious effects on various vegetables and generally increases the yield by 5 to 7 days and increases the yield by 4 to 43%. Through research initially determined the appropriate spray concentration, time and spray and application methods. Concentration: 0.5ppm for leafy vegetables and 1.0ppm for fruits and vegetables. Spraying season: Leafy vegetables are more suitable for spraying in rapid growing season. Fruits and vegetables are more suitable for spraying in first flowering (fruit) period. Spray: Leafy vegetables From the seedling growth period to 15 days before harvest, even spray every 10 days or even 2 to 3 times is appropriate, fruits and vegetables from the first flower (fruit) period, every 10 to 15 days, and even spray 3 to 4 times as should. Celery using triacontanol, Chinese cabbage, cucumber, green pepper, sugar, Vc and other dry matter accumulation have increased; and can reduce the incidence of some vegetable diseases.
