20 yuan per jin, subverting the tradition

Mr. Tang from Jiangxi planted a new type of colored cauliflower. By chance in 2015, Mr. Tang saw this kind of colored cauliflower after an agricultural exhibition. He thought it was very novel and characteristic, so he tried to grow it on a small scale. In the first year of planting, many local hotels ordered colored cauliflower from him, and it was in short supply.

Mr. Tang saw a business opportunity in colored cauliflower and began to plant it on a large scale in the second year. In addition to the hotels supplied in the first year, another part went to the market, with the first wholesale price of 20 yuan per jin, and the income this year was as high as several hundred thousand yuan. The income is three times that of ordinary cauliflower!

Planting benefit

Up to this year, Mr. Tang has been growing colored cauliflower for three years. After years of experience, Mr. Tang summed up a set of differences in yield harvested in different seasons:

1. The precocious harvest period is 45-60 days, and the yield per mu is 4000-5000 jin.

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

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

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

Planting technology

Cultivation season

The seedlings were cultivated in the open field in autumn and winter from July to August, the seedlings were 30-35 days old, planted from August to September, and went on the market from October to February of the following year. The seedlings were raised in hotbed in spring, the seedling age was about 60 days, the flower bulb was formed from 4 to 5 months, and harvested before the arrival of high temperature. Large area cultivation, can refer to common cauliflower planting. For ornamental cultivation, flowerpot sowing can be used.

Colonization

Spring cauliflower seedlings have 5-6 leaves and autumn cauliflower 4-5 leaves. Ridge cultivation or border cultivation, spring should not be planted too early, severe frost can cause cauliflower frost damage, low temperature for a long time to form a small floret. The row spacing of early-maturing varieties is 53-60 cm, and the plant spacing is 40-45 cm. The row spacing of medium-maturing varieties is 60cm to 70cm and the plant spacing is 45cm to 50cm. The row spacing of late-maturing varieties is 70-80 cm, and the plant spacing is 50-60 cm. [3]

Potted plant

When the plant is 10-12 cm in height and 5-6 true leaves, it is transplanted to a round basin with a diameter of 20-40 cm. The potted soil was prepared with 4 parts of garden soil, 3 parts of stable manure and 3 parts of rotten leaf soil, with 5 grams of compound fertilizer in each pot and fixed root water after planting. The 3-5 pots are arranged into a row, and the footpath between the borders is 60-80 cm wide. The temperature is low in spring and can be placed in the greenhouse. If the temperature is high in summer, it can be placed in the rain-proof shed of sunshade net for 1-2 months.

Administration and Management

Ploughing, loosening soil and weeding in time after planting, hot weather in autumn, should be watered in time. Boron deficiency in the soil will cause the center of the flower stem to crack, and in severe cases, the flower ball becomes ferruginous. 0.1 grams of borax is used as the base fertilizer per square meter of soil, and 0.2% boric acid solution is sprayed on the leaves during the corm expansion period. Cauliflower pests are serious, you can refer to the control methods of common cauliflower.

Traditional cauliflower vs color cauliflower

Compared with traditional cauliflower, colored cauliflower has higher nutritional value and market prospect. In addition to the domestic market, colored cauliflower also has ultra-high international market value.

The habits of colored cauliflower and common cauliflower are basically the same, both like cold climate, and it is easier to cultivate, but compared with ordinary cauliflower, colored cauliflower has better economic benefits.
