Planting time and method of cauliflower

Cauliflower is a kind of vegetable that specializes in eating flowers, and there is a saying "waiting for you to wait for cauliflower to get cold". In fact, cauliflower usually tastes better with cold salad, and there will be kimchi when eating kimchi. Cauliflower is particularly beautiful when it blossoms, if a large area of cauliflower is planted, it is a beautiful scenery, and its nutritional value and medicinal value are relatively high, so today we will learn about the planting time and method of cauliflower.

Planting time

Cauliflower is still a kind of seasonal vegetable in the market, and it can be produced only in a certain season. Cauliflower is usually produced from June to August. Cauliflower can generally be planted for two seasons, so spring and autumn are the normal planting time for cauliflower. Its growing period is divided into seven stages, namely, budding, leaf spreading, bolting, flowering, leaf withering, leaf spreading and dormancy in the coming year. This also shows that the planting of cauliflower can continue the harvest for several years, which is very affordable.

Planting method

1. Land selection and preparation

Cauliflower is not very strict with the sudden requirements. Its ability to resist barren and drought is very strong, and its life span is relatively long. It can generally grow for five to eight years, so it is more planted alone in hillsides, mountains, and other areas. However, if you can plant in places where the soil is relatively loose and fertile, it will grow better, its yield will be higher, and its service life can be extended at the same time. Dig as deep as possible after preparing the ground, so as to avoid the threat of some insect pests and prevent lodging at the same time.

2. Planting mode

There are two ways of planting cauliflower, the first is to sow and raise seedlings, put the seeds of cauliflower into the seedling bed, and wait for the advantages of the seedlings for transplanting, but this method has two disadvantages, that is, the yield is not high and the quality is not good. Secondly, it will not blossom until the third year after planting, and the normal yield can only be achieved in the fourth year, so the first way is generally not recommended. The second way is to propagate through ramets, after harvesting cauliflower in autumn or after dormancy, plant the new roots on the old seedlings separately, so that they can blossom and harvest in the coming year after planting, and the efficiency will be much higher. If there is no old seedling, you can buy it from someone else.

3. Field management

Cauliflower should be planted according to a reasonable density, usually 35 to 40 centimeters apart per plant. The most suitable temperature for the growth of cauliflower is about 15 to 20 degrees, so temperature control is needed during its flowering period, which can promote flowering and improve quality and yield. The most important thing for cauliflower is fertilization management. generally speaking, we have to apply fertilizer three times. The first fertilization is at the time of germination, and the mixed fertilizer of nitrogen, phosphate, potash and urea is used to promote germination and shorten the budding period. The second fertilization generally uses urea and potash fertilizer to promote the growth of new branches, and the last fertilization is at the time of flowering, which is conducive to shortening the flowering period for harvest.

4. Disease prevention

The disease of cauliflower is relatively less, that is, sometimes there are some aphids, or leaf spot disease, so when there are few aphids, you can get rid of insects manually, you should spray dimethoate EC more, and you can't harvest it within half a month after spraying. Secondly, chlorothalonil is generally used for leaf spot disease.

5. Harvesting and processing

Cauliflower usually blossoms at night, so it is usually harvested every morning and withered at noon. If you encounter a rainy day, try to harvest one day in advance, then its growth rate is very fast, if it is still in accordance with the previous time, it will be useless. After harvest, the cauliflower should be processed. It is generally steamed and dried, then dried in the sun, and finally packed.
