When is cauliflower usually planted and harvested? How long is the growth cycle? What's the difference between and broccoli? Attached storage and fresh-keeping methods

Cauliflower, also known as cauliflower, cauliflower or cauliflower, cauliflower, broccoli, cauliflower, kale, is a very popular vegetable. So when will cauliflower be planted and harvested? How long is the growth cycle? What's the difference between and broccoli? What are the methods of storage and preservation? It is learned from grower Wu Xiangsheng that the growth period of very early-maturing varieties is 30-40 days, that of early-maturing varieties is generally 50-60 days, that of middle-maturing varieties is 70-90 days, and that of late-maturing varieties is more than 90 days.

When will cauliflower be planted and harvested?

Planting:

Cauliflower sowing time normally begins to sow in autumn, grows in winter, and is normally listed on the table after the Spring Festival. It begins to blossom in spring and the seeds mature in April and May. Raising seedlings in summer and autumn: raising seedlings in the high temperature season from August to October. At this time, the temperature is generally above 25 ℃, sometimes with a high temperature of 30-35 ℃, coupled with the harm of rainstorm and hail, so shading net is used to raise seedlings in the open field. The seedling age is generally 35-40 days. Sowing or direct burrowing can be used. The average seedling stage is about 30 days, from planting to harvest 80-90 days. The seedling stem diameter 10mm can accept the influence of low temperature and complete the vernalization process.

Harvest:

There is a great difference in climate between the north and south of China, and there are also obvious differences in planting varieties in different places. According to the maturity, cauliflower varieties are divided into very early-maturing varieties, early-maturing varieties, middle-maturing varieties and late-maturing varieties, which are generally harvested in autumn and winter.

What's the difference between broccoli and broccoli?

Broccoli and cauliflower are not the same vegetables. In fact, broccoli and cauliflower belong to cruciferous cabbage vegetables, but one white and one green is a pair of "sister flowers" of the cabbage family. So cauliflower is not broccoli, there is a slight difference between the two.

1. Cauliflower, also known as cauliflower, cauliflower or cauliflower, is a cruciferous vegetable and a variety of cabbage. The head of cauliflower is a white inflorescence, similar to broccoli. Cauliflower originates from the Mediterranean coast, and its product organs are white, shortened, fat and tender buds, branches, rachis and so on. It is a vegetable with low crude fiber content, fresh quality, rich nutrition, delicious flavor and people like to eat.

2. The morphological characteristics and growth habits of broccoli are basically similar to those of common cauliflower, belonging to Brassica campestris, 1-2-year-old herbaceous plants. The plant is tall, about 20 flower stems are drawn out according to the leaf growth of different varieties, and the apical buds are grouped. Closely clustered into a flower ball, the shape is hemispherical, the buds are turquoise, so it is commonly known as broccoli. The leaves of broccoli are blue-green and turn to dark blue-green gradually, with thickened wax layer and long and narrow petiole. Its leaf shape has two kinds of broad leaves and long leaves. The rhizome is thick, the epidermis is thin, the water content in the middle medullary cavity is large, fresh and tender, and the root system is well developed.

Attached: storage and fresh-keeping methods of cauliflower

The storage tolerance of different varieties of cauliflower is different. only by selecting storage-tolerant varieties can storage and fresh-keeping be realized and considerable economic benefits can be obtained. at present, the storage-tolerant varieties are mainly middle-and late-maturing varieties, and early-maturing varieties are not suitable for storage. In order to arrange the sowing time according to the growth period of the variety and the local suitable storage period, it is generally better to sow and plant later than fresh cauliflower, so that the harvest time can be harvested before freezing, the temperature is high, it is not easy to store, and the yield is low. In cultivation and management, the method of furrow irrigation should be adopted instead of flood irrigation, with little or no watering 7-10 days before harvest, and outer leaves should be covered in the middle and later stages of flower head growth to protect it from sun exposure and freezing. On the basis of applying appropriate amount of nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer.

1. The standard of flower head suitable for cauliflower storage is a medium flower ball with a diameter of about 15 cm and a weight of 0.5-0.8 kg. The bouquet is dense, white, pest-free, virus-free, damage-free and pollution-free.

2. During harvest, if you plan to carry out short-term storage for about 2 months, you can leave 4-6 leaflets to protect the flower bulb, which is also conducive to the preservation of vitamin C. if the storage period is more than 2 months, you should store the flower ball without leaves, because the leaves are easy to rot in the later stage of storage, so that the flower ball has a moldy flavor, affecting the flavor of the flower ball, thus losing its edible value. When harvesting, the damage of the bouquet should be avoided, because the damaged bulb turns yellow and dark, brown spots and rot appear during storage.

3. The suitable temperature for storage of cauliflower is 0-1 ℃, and the temperature is too high, especially when the temperature is more than 10 ℃, it is easy to cause discoloration, bolting, water loss, shrinkage and rot, and lose the storage value. When the temperature is lower than 0 ℃, it is easy to appear frost injury, local transparency and brown spots after rewarming, which affect the flavor and storage of the bulb. The relative humidity suitable for cauliflower storage is 90%-95%, the humidity is too low, the rosette is easy to be dehydrated, shrunk and weak, the flower branches are loose, and lose commodity value and edible value.
