Management techniques of cauliflower after harvest

Cauliflower is a kind of precious wild vegetable in our country, which is distributed all over our country. It has the effects of anti-inflammation, clearing heat, clear eyes and tranquilizing nerves. It is a kind of wild vegetable with high nutritional value, and now it is gradually beginning to be planted artificially. The growing period of cauliflower is in spring and autumn, and it will gradually enter the dormancy period after harvest, but this period is more important, good management can ensure high yield year after year. Then let's take a look at the management technology of cauliflower harvest with the editor.

1. Pull the rod and cut the leaves

After harvest, the stem of cauliflower will gradually dry up, we should pull out the stem in time, but we should also pay attention to the state of the stem. Do not pull out the stalks that have not completely dried up to avoid hurting the roots. At the same time, the old leaves about 4 cm from the ground should be cut off, which should not be cut too low, otherwise it will hinder the germination of hidden buds. If you cut too much, it will consume too much nutrition, so it is necessary to grasp the distance. Pulling stems and cutting leaves can promote the growth of seedlings and increase the number of flower branches in the coming year, which is of great help to the increase of yield.

2. Clear the garden for disinfection

Leaf blight, aphids and other diseases and insect pests often occur in the cultivation of cauliflower, so we should do a good job of garden cleaning and disinfection in autumn and winter, which can effectively control diseases and insect pests. If the disease still occurs after harvest, it should be disinfected separately in autumn and winter, remove the weeds in the field, and then burn them together with the diseased leaves of cauliflower. Mixing ash into the soil not only reduces the source of diseases and insect pests, but also improves the soil fertility.

3. Deep turning fertilization

After the whole growth period of cauliflower, due to field management, the soil was trampled for a long time, resulting in soil consolidation. Therefore, we should choose sunny days to dig deep into the soil in summer to promote the growth of autumn seedlings, improve the ability of roots and enhance the growth of plants. First of all, hollowed out around the plant, then eradicate the dead roots of the old roots, and then fill them up to prevent leakage of the roots and avoid root burning. When deep ploughing, it should be applied together with base fertilizer to control the dosage, improve soil fertility and promote the growth of seedlings.

4. Renewal and rejuvenation

The heavy rainfall in summer is very beneficial to the renewal of cauliflower. First of all, we have to select the lily with weak growth, dense roots, few new roots and thin plants for replanting. Then burn the areas where the disease and insect pests are serious, and then replant healthy seedlings. It can also appropriately expand the planting area, eliminate impure varieties in time, ensure the healthy growth of cauliflower, increase the yield and enhance the quality.

5. Cultivate the soil and protect the soil.

In planting, cauliflower can be harvested many times a year, and new roots will grow on new stems every year. If the soil is not cultivated in time, it will always grow up and be exposed to the air. Therefore, we must do a good job in soil cultivation in winter, and it is best to use pond mud and paddy field mud, or the original cultivated soil. Heat preservation of new roots can improve cold resistance, prevent frost injury and reduce the production of ineffective tillers.

The above is a brief introduction to the post-harvest management technology of cauliflower, because cauliflower is more than one year old, so the management after each harvest is very important. Improper management will seriously hinder the subsequent growth, reduce the yield and lead to the decline of planting efficiency. That's all for today's introduction.
