Planting techniques of cauliflower

I. Seedling management:

The seedlings were propagated by seeds, slices, moss axils and ramets on the seedling bed. At the seedling stage, one bag of kalium dihydrogen phosphate 100 grams (22) urea 50 grams (one or two), 30 jin of water were sprayed every 1-2 months, and the seedlings were formed much earlier. When the seedlings were transplanted to the field, the roots and the branches and leaves of the whole plant were soaked for 3 minutes with a bag of 100 grams of potassium dihydrogen phosphate, 50 grams of urea and 15 jin of water, and the survival rate was extremely high.

Second, seedling management:

The yellow flower seedlings transplanted into the field were sprayed with 1 bag (10 grams) of potassium dihydrogen phosphate 100 grams (two pairs) urea and 30 jin of water for 3 times, which greatly promoted the growth and entered the flowering stage ahead of time.

Third, florescence management:

Spraying should be carried out at the bud and flowering stage, or after each flower harvest, including one bag of Chinongsu, 100 grams of boron fertilizer (two pairs), 4 bags of gibberellin (0.25 grams), 50 grams of zinc sulfate (one or two), and 100 grams of potassium dihydrogen phosphate (2 pairs). Spray 30 jin of water. Every time the flowers are picked or sprayed every 20 days, there will be significant flowers, and the number of flowers can be doubled. Generally speaking, the increase in production is more than 30%, and the yield of dried flowers per mu can reach 800 jin.

Fourth, prevention and control of diseases and insect pests:

Use Qinongsu 1 bag (10 grams) to kill 1 imidacloprid and 1 bag of urea 50 grams (one or two), add water about 30 jin.

Fifth, the economic benefits are remarkable:

The ratio of input to benefit is more than 50%, 10% and 50%. The benefits include saving seeds, pesticides, fertilizers and increasing production artificially.
