When will the "poor doctor" cauliflower be planted? How to grow high yield? How much do you earn from planting an acre?

Cauliflower, also known as kale, cauliflower and cauliflower, is a common vegetable in China. It is deeply loved by people because of its high vitamins and mineral elements. At present, cauliflower is grown in many areas of our country. When will cauliflower be planted? How to grow high yield? How much do you earn from planting an acre?

Cauliflower planting time:

Spring cauliflower should be planted in greenhouse or sunny bed in late December and planted in protected field in the first and middle of March. Open field cultivation should be planted from late March to early April, not too early or too late, and autumn cauliflower should be sown strictly. Generally, it should be sown from late June to early July, planted from late July to early August, and harvested from the end of September to the end of October.

The temperature is low in spring, the seedling grows slowly, the seedling age is generally 45-60 days, with 4-5 true leaves can be planted. If the seedlings are planted in the open field in the shed, the temperature and humidity in the shed should be adjusted according to the appropriate period of planting in the open field, so as to ensure that the seedlings can be transplanted on time.

The sowing time is slightly different between the north and the south, and the autumn sowing time is between June and July.

Planting method:

First, choose a good variety. It is suitable to use mid-and late-maturing varieties in spring and early and mid-maturing varieties in autumn.

Second, sowing and planting at the right time. Spring cauliflower should be planted in greenhouse or sunny bed in late December and planted in protected field in the first and middle of March. Open field cultivation should be planted from late March to early April, not too early or too late, and autumn cauliflower should be sown strictly. Generally, it should be sown from late June to early July, planted from late July to early August, and harvested from the end of September to the end of October.

Third, cultivate strong seedlings of the right age. Using nutrition bowl to raise seedlings, autumn cauliflower germination stage and seedling stage are in high temperature and rainy season, so shading measures should be taken. Generally, autumn cauliflower seedling age should be planted at 25 min 30 days, when 5 mi 6 leaves, spring cauliflower seedling age should be controlled at 70 mi 80 days, 5 mi 7 leaves should be planted.

Fourth, ensure the supply of water and fertilizer. After cauliflower planting, combined with watering slow seedling water, 10 kg urea per mu can be applied, and then start squatting seedlings, end squatting seedlings when the bulb diameter is about 3 cm, apply 25 kg urea per mu with watering, and then irrigate every 4 times every 5 days, pay attention to keep the border surface wet.

Pay attention to the prevention and control of insect pests. Spray with 2.5% enemy kill 5000 times and 20% quick kill 2000 times to control aphids and cabbage insects, and be careful not to use highly toxic pesticides.

Sixth, cover the flowers in time and harvest at the right time. When the floret is formed, the method of folding leaves inward can be taken to cover the bouquet in time and meticulously, the bouquet is fully grown, white, dense, the surface is straight, and the edge has not yet spread out, it is the harvest period.

Planting benefit analysis:

Cauliflower is generally sown in early spring and autumn. The yield in autumn is higher than that in spring. Take autumn sowing as an example:

1. The precocious harvest period is 45-60 days. Take Yamei as an example, the yield per mu is 4000-5000 jin.

2. The harvest period of mid-maturity is 65-80 days, and the yield of Hua Fei is 4500-6000 jin per mu.

3. The harvest time of late-maturing varieties is 85-100days, the average yield of Baisheng King is 6000-7000 jin per mu, and 6500-8000 jin in 100 days in winter.

The price of cauliflower fluctuates with the market supply, and it is easy to get high price in out-of-season cultivation.
