How to Solve Cauliflower Nodule Disorder
In the production of vegetables, the peasants will encounter a bad situation with cauliflower. The following measures should be taken to solve the cauliflower problem and improve the yield and quality.
First, choose a good variety. In the spring, it is appropriate to use medium and late-maturing varieties, and in the autumn, early and middle-maturing varieties are suitable.
Second, appropriate sowing and planting. Spring cauliflower should be planted in the greenhouse or Yangshuo in late December, and planted in the middle and mid-March; open field cultivation should be planted in late March to early April. It should not be too early or too late. Autumn cauliflower should be strictly planted, generally 6 Sowing from late July to early July, planting from late July to early August and harvesting from the end of September to the end of October.
Third, nurture age-appropriate seedlings. The use of nutritional seedlings nursery, autumn cauliflower germinating and seedling stage is in high temperature and rainy season, measures should be taken to cover the shade, the general autumn cauliflower seedlings in the 25-30 days, 5-6 leaf when the planting, spring cauliflower seedling age in 70- 80 days, 5-7 leaves when planting.
Fourth, ensure the supply of water and fertilizer. After the cauliflower is planted, combined with watering of the seedlings, 10 kg of urea can be applied per acre. Then the seedlings are started. When the diameter of the flower ball is about 3 cm, the seedlings are finished, and 25 kg of urea is applied with the watering mu, and then poured every 4 to 5 days. Once in water, be careful to keep your face moist.
Fifth, pay attention to pest control. With 2.5% enemy killed 5,000 times the liquid, 20% speed kill Ding 2000 times liquid spray, can control aphids and cabbage caterpillars, pay attention not to use highly toxic pesticides.
Sixth, timely flowers, timely harvest. When the ball of flowers is formed, the method of folding the leaves inwards can be adopted to timely and carefully cover the flower balls. The flower balls are fully grown, white, and dense in texture. When the surface is round and the edges have not been scattered yet, it is the collection period.
