Latest Technical Methods and Tutorial for Broccoli Field Management

Broccoli, commonly known as green cauliflower, is a common vegetable in our country, but many people often confuse it with cauliflower. In fact, broccoli and cauliflower are quite easy to distinguish; for example, broccoli is green in color, while cauliflower is yellow. Broccoli also has anti-cancer effects, and it is said that long-term consumption can reduce the incidence of rectal cancer and other cancers. Growing broccoli is very simple, but do you know how to carry out field management? Let's take a look together below!

1. Management during the seedling recovery period

The main management focus during the seedling recovery period is temperature and humidity. Proper management of temperature and humidity can effectively promote the seedling recovery time of broccoli seedlings. We should build a shade canopy at the top of the greenhouse to prevent direct sunlight, lower the temperature in the greenhouse, and water twice a day to maintain the humidity in the greenhouse. The probability of pest outbreaks during the seedling recovery period is relatively high, so in order to prevent pests from gnawing on the seedlings and affecting growth, a little Mirel can be sprinkled on the soil. Strengthen fertilizer management, promote seedling growth, and regularly spray pesticides to reduce the incidence of various diseases and pests.

2. Management during the rosette period

The rosette period is the vigorous growth period of broccoli, and the demand for fertilizer and water rises sharply during this period. 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. During the rosette period, the number of top dressings must not be less than two. The first is roughly about half a month after planting, and attention should be paid to the amount and distance to prevent harm to plant growth. Then carry out another top dressing before ridge closing, applying it when the heart leaves form a heart shape. This top dressing should be carried out together with weeding work, and soil should be cultivated promptly after top dressing to prevent the loss of water and fertilizer.

3. Management during the curd formation period

The curd formation period is a relatively important period for broccoli, because poor management during this period can easily cause broccoli to begin vegetative growth. This is not conducive to the formation of the curd, so during the curd formation period, the application of nitrogen fertilizer should be well controlled to prevent excessive nitrogen fertilizer from causing excessive vegetative growth in broccoli. Increase the proportion of trace elements such as phosphorus and boron in the fertilizer, and apply a heavy dressing once the curd has successfully formed. The curd often shows yellowing and hollowing, which affects the maturity of broccoli, so during the formation period, foliar fertilizer should be applied appropriately, about once every 7 days, for 3 consecutive times. Keep the field soil moist, observe the leaves, and promptly remove old leaves, weak leaves, and diseased leaves, and do a good job in disease and pest control.

4. Management during the harvest period

Before the harvest period arrives, and in the time leading up to the harvest period, regularly observe the formation of the broccoli curd. Pay attention to the growth of the leaves, and if diseased leaves or other leaves unfavorable to growth are found, remove them promptly. This can not only improve the ventilation of the field, but also reduce the incidence of disease. It promotes the concentration of nutrients on the curd. Water management during the harvest period is very important; while ensuring sufficient water supply, it is also necessary to prevent excessive water, which can cause rot and lead to various diseases and pests. When harvesting, pay attention to the harvest time. Harvesting too early means it is not mature enough, reducing commodity value and making it unfavorable for market sale. Harvesting too late increases the incidence of diseases and pests, leading to reduced yield, and it is also unfavorable for storage.

The above is a brief introduction to broccoli field management techniques. There are many growth stages in broccoli growth, and what has been introduced here are a few relatively important periods. Broccoli management is very important, and there are different management methods at each growth stage, so everyone must pay close attention! That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
