Regulators that promote the nutritional growth of cabbage
6-benzylamino-purine 6BA
Use 20~40 mg/L benzylaminopurine to spray once at 10~15 d intervals, 2~3 times in the seedling stage, clustering stage and rosette stage, which can increase chlorophyll, improve photosynthesis, and accelerate the growth and development of crops ,increase production.
Triacontanol
0.5~1.0 mg/L triacontanol was sprayed once at the rosette stage and in the early stage of the heart. After treatment with triacontanol, the plants had strong growth, fresh leaves, enhanced disease resistance, and early maturity. 2 ~~5 d, the yield increased by 10.8%~16.3%.
Sodium Nitrophenolate
Use 4~6 mg/L sodium nitrophenolate solution to spray 3~4 times at the initial stage of planting, rosette stage and leaf bulb formation stage.Spraying 50 kg of medicinal liquid per acre can promote rooting, reduce diseases, promote growth, improve quality, mature early, and increase yield by 20% to 30%.The cabbage is sprayed 2~3 times on the leaves after planting, with an interval of 7~10 d each time, and spraying 50 kg of liquid medicine each time can promote the yield increase by 10%~20%.
Yield
In the cardiac period, spraying twice with 20-30 mg/L liquid medicine can obviously promote growth and increase yield.
Diethyl aminoethyl hexanoate
Spray the stems and leaves with 50~66.7 mg/L liquid medicine evenly for 3 times in the seedling stage, rosette stage and head stage, which can improve the photosynthetic rate and the activity of peroxidase and nitrate reductase;Improve the metabolism of carbon and nitrogen in plants, enhance the absorption of water and fertilizer by plants, and adjust the water balance in plants, thereby improving the drought and cold resistance of plants.
Brassinolide
0.013~0.02 mg/L rutinolide solution was sprayed once in the seedling stage and the vegetative growth stage, which can promote the obvious thickening of the mesophyll of cabbage, deepen the leaf color, and the fast growth speed can lead to early clustering, and the quality of the balls is good. Significant increase in births.
Diethyl aminoethyl hexanoate and brassinolide
5% Brassinolide and diethyl aminoethyl hexanoate (0.001:5) were sprayed with 1000-1500 times the concentration of the medicinal solution in the rosette stage, and reapplied at 10d intervals, which could significantly increase the yield, which was significantly higher than that of a single dose.Or in 30 days after sowing, when the Chinese cabbage leaves 10-11 leaves, the yield increases greatly, the concentration is preferably 1000 times, and the final yield increases by 15.73%.
Gibberellic acid GA3
When the non-heading cabbage grew to 4 true leaves, it was treated with 20-75 mg/L gibberellic acid twice. After 20 days, the length and width of the leaves were increased compared with the control, and the yield could be increased by about 40%.
