For the removal of weeds and diseases should be taken out of the countryside in time to eliminate, but also appropriate spraying fungicides to reduce the occurrence of field diseases and insect pests.

2. deep ploughing and fine ploughing of the land. Soil is an indispensable necessary condition for crop growth, so deep ploughing and fine ploughing should be carried out to improve the soil environment. One group should be carried out in sunny weather, the best depth is 25-30cm, cut off the senescent roots of cauliflower and promote the growth and rooting of new roots.

How to deal with cauliflower on rainy days

On rainy days, only some paclobutrazol and dwarftin can be sprayed on the surface of cauliflower to inhibit florescence and prolong florescence, but the other effects are not very obvious. On rainy days, the flower buds of cauliflower grow fast and blossom early, and the harvest time needs to be advanced appropriately. The flower buds of cauliflower are blooming one after another, so keep picking on time every day after picking, no matter whether it is cloudy, sunny, windy or rainy, otherwise it will reduce the commodity value of cauliflower.

How to control the disease of cauliflower

1. The most threatening disease of cauliflower anthracnose is the leaf. The robe of the pathogen is attached to the plant with the activity of insects, and the disease is most likely to occur in a warm and humid environment. First of all, there will be some brown spots on the edge of the leaf, and finally, with the reasoning of time, there will be black rot and perforation in serious places. It is found that 1000 times topiramate can be used for prevention and treatment after the attack, and it is best to spray 1-3 times after the disease is cured, with an interval of one week to avoid recurrence.

2. Rust is also a serious influence on cauliflower, the disease is mostly concentrated in the stem cadre position, the diffusibility is very high, and the onset time is before and after the bud formation. When the disease occurs, there will first be rusty irregular spots on the plant, and then slowly spread around and connect together, and in serious cases, the whole plant seems to be rusty. The better control agent is 25% trimethoprim WP1000 solution, and all plants had better be sprayed after discovery.

Picking and processing of cauliflower

1. Picking cauliflower should be picked in time every day, the early mature should be picked first, and the late mature should be picked later. If the buds are not fully expanded and the yield is low when harvested prematurely, the yield and quality will also be affected if the buds are harvested too late. Mature cauliflower buds are yellowish green and full, with obvious vertical grooves on the petals and budding.

2. Cauliflower processed into dried products should be steamed in time after picking. The harvested cauliflower is neatly discharged into a steaming sieve and the flower height is not more than 5 cm. Moderate standard of steaming: the color changes from yellowish green to light green, gently kneading the buds with your thumb and forefinger to make a sound. Generally steamed at high temperature for 8 minutes. The function of steaming is to quickly kill the activity of the cells inside the bud to facilitate drying.

After picking cauliflower, we must do a good job in the management of weeding and diseases. If it rains, some medicine should be sprayed in time to slightly prolong its flowering period. If cauliflower waits for diseases, it needs to strengthen prevention and management, so as not to make its harm more serious.
