Broccoli, commonly known as broccoli, is a common vegetable in China, but many people often confuse it with cauliflower. In fact, there is a good difference between broccoli and cauliflower. For example, broccoli is green and cauliflower is yellow. Broccoli also has anti-cancer effects, and it is said that long-term use can reduce the risk of cancers such as rectal cancer. Growing broccoli is easy, but do you know how to manage it in the field? Let's take a look at it with the editor.

1. Management at slow seedling stage

The main management direction of slow seedling stage is temperature and humidity. Good management of temperature and humidity can effectively promote the slow seedling time of broccoli seedlings. We should build a sunshade at the top of the greenhouse to prevent direct sunlight, lower the temperature in the greenhouse, and water it twice a day to maintain the humidity in the greenhouse. The occurrence rate of insect pests in slow seedling stage is higher, so in order to prevent pests from eating seedlings and affect growth, you can sprinkle a little milol on the soil. Strengthen fat management, promote the growth of seedlings, spray pesticides regularly to reduce the incidence of various diseases and insect pests.

2. Rosette management

The rosette period is the peak growth period of broccoli, during which the demand for fertilizer and water increases sharply. Therefore, during this period, we should strengthen the application of fertilizer and water, promote the growth of stems and leaves, strengthen nutrition, and increase the yield of broccoli. In the rosette period, the number of topdressing should not be less than twice, the first one is about half a month after planting, pay attention to the dosage and distance to prevent damage to plant growth. Then fertilize again before closing the ridge, and beware of topdressing when the leaves form a heart. The topdressing should be carried out together with the weeding work, and the soil should be cultivated in time after topdressing to prevent the loss of water and fertilizer.

3. Management of ball setting period

The heading period is an important period for broccoli, because poor management in this period can easily lead to the vegetative growth of broccoli. It is not conducive to the formation of flower heads, so it is necessary to control the application of nitrogen fertilizer during the heading period to prevent excessive nitrogen fertilizer from causing broccoli to grow too much. The proportion of trace elements such as phosphorus and boron in fertilizer was increased, and the flower head was successfully formed and re-applied. The flower bulb is often yellowed and hollow, which affects the maturity of broccoli, so foliar fertilizer should be applied properly during the formation period, about once every 7 days for 3 times. Keep the soil moist in the field, observe the leaves, remove the old leaves, weak leaves and diseased leaves in time, and do a good job in pest control.

4. Harvest time management

Before the harvest time, the formation of broccoli bouquet should be observed regularly. Pay attention to the growth of leaves, if found that diseased leaves and other leaves are not conducive to growth should be removed in time. It can not only improve the permeability of the field, but also reduce the incidence of disease. Promote the concentration of nutrition on the bouquet. Water management during the harvest period is very important to ensure sufficient water demand and at the same time prevent excessive water, resulting in decay and various diseases and insect pests. When harvesting, pay attention to the harvest time, harvesting too early is not mature enough, reduce the value of goods, is not conducive to listing and sale. Harvesting too late increases the incidence of diseases and insect pests, resulting in a decline in yield, and is not conducive to storage.

The above is a brief introduction to the field management technology of broccoli. There are many growth stages in the growth of broccoli, and the editor introduces several more important periods. The management of broccoli is very important, there are different management methods in each growth stage, we must pay more attention to it! That's all for today's introduction.
