Key points of cultivation techniques of broccoli

Broccoli is widely planted in China, and it is also very popular in China, but broccoli is different from cauliflower. So the planting methods are also very different, but many people do not know that according to the cultivation techniques of cauliflower lead to cultivation failure. So how to grow broccoli? Today, the editor has brought you the key points of broccoli cultivation techniques. Let's take a look at it.

1. Ploughing and weeding

Intertillage weeding is one of the important cultivation techniques in the process of broccoli planting, which should be carried out together with topdressing in the early stage of broccoli growth. First of all, before planting, wet the soil with enough water, and then spray it evenly and comprehensively on the border surface with appropriate amount of cable agent according to the cultivated area. However, it is not suitable to move the soil and then colonize, which can effectively inhibit the growth of weeds. In the process of broccoli planting, according to the growth situation and the softness of the soil, ploughing in time to improve the soil permeability and promote the absorption of nutrients in the roots of broccoli. However, it is not suitable to carry out intermediate ploughing after the closure.

2. Topdressing in time

The growth of broccoli has a great demand for drinking, and the size of the plant determines the final size of the bulb. Therefore, in order to ensure the bulb expansion and improve the quality, we must first ensure the luxuriant growth of the plant, so it is necessary to topdressing in time to promote the growth of the plant. The amount of fertilizer is relatively large in the early growth stage and bolting stage of broccoli, so it is necessary to apply more nitrogen fertilizer and properly add phosphorus and potassium fertilizer, otherwise it may lead to early budding. Then in the peak growth period of broccoli, we should not only ensure the use of nitrogen fertilizer, but also supplement some trace elements, and properly spray foliar fertilizer to promote the growth of flowers and leaves. Comprehensive nutrition is the key to ensure the high yield of broccoli, so timely topdressing is essential.

3. Water management

Broccoli is more suitable for growing in a humid environment, and the water demand is also relatively large, so it is necessary to ensure that the soil is in a moist state during growth. Especially after flower bud differentiation, when entering the stage of flower ball formation, the demand for water will be further expanded. If there is a lack of water during this period, it will affect the formation of flower heads and reduce the yield and quality of broccoli. The soil water content can be controlled at 75%. If there is too much water content, it will increase the incidence of plant diseases and insect pests and lead to flower ball rot. It is necessary to maintain sufficient moisture before harvest, otherwise the bouquet harvest will be loose, deformed and reduce the commodity value.

4. Pest control

The prevention and control of diseases and insect pests is a key point that we should pay attention to. We should strengthen field management, reduce field germs and reduce morbidity. If broccoli gets sick, it is very easy to cause other diseases and insect pests, such as black mildew if it is not treated in time after suffering from downy mildew. Aphids also carry the pathogens of viral diseases. No matter what the diseases and insect pests are, the threat to broccoli plants is very great. Therefore, we should regularly inspect the vegetable garden, find that abnormal situations should be dealt with in a timely manner, and prepare agents for the prevention and control of various diseases and insect pests to avoid unnecessary losses.

The above is a brief introduction to the main points of broccoli cultivation techniques. Although broccoli is similar to cauliflower, it can not completely copy the planting method of cauliflower. Therefore, before planting, we should make full preparations, such as planting techniques, key points of management, preparations for pest control, and so on.
