Detailed Explanation of Broccoli Field Management Techniques
Broccoli, commonly known as green cauliflower, is a common vegetable in China, but many people often confuse it with cauliflower. In fact, broccoli and cauliflower are quite easy to tell apart; for example, broccoli is green, while cauliflower is yellow. Broccoli also has anti-cancer properties, and it is said that long-term consumption can reduce the incidence of colorectal cancer and other cancers. Growing broccoli is 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 focus of management during the seedling recovery period is temperature and humidity. Proper management of temperature and humidity can effectively shorten the seedling recovery time of broccoli seedlings. We should build a shade canopy on top of the greenhouse to prevent direct sunlight, lower the temperature inside the greenhouse, and water twice a day to maintain humidity in the greenhouse. The incidence of pests is relatively high during the seedling recovery period, so to prevent pests from eating the seedlings and affecting growth, a little Miral can be sprinkled on the soil. Strengthen fertilizer management to promote seedling growth, and spray pesticides regularly to reduce the incidence of various diseases and pests.
2. Management During the Rosette Period
The rosette period is the period of vigorous growth for 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 to promote the growth of stems and leaves, enhance nutrition, and increase broccoli yield. The number of topdressings during the rosette period 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 damage to plant growth. Then apply another topdressing before ridge closing, applying it when the heart leaves form a heart shape. This topdressing should be carried out together with weeding work, and soil should be cultivated promptly after topdressing to prevent loss of water and fertilizer.
3. Management During the Heading Period
The heading period is a relatively important period for broccoli, because poor management during this period can easily cause broccoli to begin vegetative growth. This is unfavorable for head formation. During the heading period, nitrogen fertilizer application should be controlled to prevent excessive nitrogen 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 application once the head has successfully formed. Heads often show yellowing and hollowing, which affects broccoli maturity, 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, 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, during the period before harvest, regularly observe the formation of broccoli heads. Pay attention to leaf growth, and if diseased leaves or other leaves unfavorable to growth are found, remove them promptly. This can not only improve field ventilation but also reduce the incidence of disease. It promotes the concentration of nutrients in the head. Water management during the harvest period is very important. While ensuring sufficient water demand, it is also necessary to prevent excessive water, which can lead to rot and produce various diseases and pests. When harvesting, pay attention to the harvest time. Harvesting too early means insufficient maturity, reducing commercial value and making it unsuitable for market sale. Harvesting too late increases the incidence of diseases and pests, leading to reduced yield and making storage unfavorable.
The above is a brief introduction to broccoli field management techniques. There are many growth stages in broccoli growth, and the ones introduced here are several 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.
