Latest Key Technical Points for Cauliflower Field Management
Cauliflower, also known as cauliflower, is a plant belonging to the cruciferous family, native to Europe, and was gradually introduced to China in the 19th century. Cauliflower is very popular in our country, with a fresh and sweet taste, delicious flavor, and very high medicinal value. Its nutritional richness ranks among the top of many vegetables. Nowadays, many people grow cauliflower, but many people do not know how to manage it. Below, the editor brings you the field management methods for cauliflower. Let's take a look!
1. Water Management
Cauliflower plants are taller and larger than ordinary vegetables, so they have relatively high water requirements during growth. After sowing and emergence, appropriate watering to promote seedling growth should be done. Keep the soil moist, but pay attention to the amount of water and prevent waterlogging in the field, so as to promote root establishment of cauliflower. Ensure that the field drainage ditches are always unobstructed, so as to cope with sudden rainstorm weather and drain water in time. The rosette stage and flowering stage of cauliflower are when cauliflower has the greatest water demand, so sufficient water supply must be ensured at this time. It should be noted that when watering, do not use flood irrigation, to prevent root rot from waterlogging.
2. Reasonable Topdressing
As mentioned just above, cauliflower plants are relatively large, so they not only have a high water demand, but also have very high fertilizer requirements. As with water demand, during the rosette stage and flowering stage, the fertilizer requirement also increases. In these two stages, we should increase the proportion of nitrogen fertilizer in the fertilizer to promote the growth of cauliflower. During the vigorous growth period, sufficient trace elements should also be supplemented to ensure comprehensive nutrition and prevent malnutrition in cauliflower. Then carry out reasonable topdressing according to the growth condition of cauliflower. However, after topdressing, everyone should pay attention to proper watering to prevent burning caused by excessive concentration.
3. Breaking Leaves to Shade the Curd
From the flowering stage to the enlargement stage, cauliflower must be properly covered. If it is not covered in time, the growth of flower buds will be hindered. The color changes from pale yellow to purple, and in severe cases yellow fuzz and new leaves will grow, causing a decline in quality. Therefore, when the cauliflower curd grows to the size of a fist, the leaves should be broken in time to cover the flower buds and prevent direct sunlight. If there are not enough leaves, rice straw can be used to tie the inner leaves together, and after the curd appears, the old leaves can be folded inward to cover the curd.
4. Disease Control
Diseases may occur throughout the entire growth cycle of cauliflower, and different growth stages will produce different pests and diseases. Some diseases also occur at any growth stage. Pests and diseases will seriously threaten the yield and quality of cauliflower and affect the economic benefits of planting. Therefore, we must strengthen management, regularly disinfect the vegetable garden, remove diseased residues in the garden, and pull out diseased plants to prevent the spread of the disease. After the disease occurs, the specific pests and diseases should be identified immediately, and then the corresponding pesticides should be used for spraying control to reduce the affected area.
The above is a brief introduction to cauliflower field management techniques. No matter what crop is planted, field management is very important. The quality of management is directly linked to the yield of cauliflower, so when planting, everyone must not be lazy and should make a management schedule to avoid unnecessary losses.
