Detailed explanation of key broccoli cultivation techniques: master scientific planting and management methods
Broccoli is grown over a very wide area in China and is also very popular here, but broccoli is not the same as cauliflower. So the growing methods are also quite different, yet many people do not know this, and they follow cauliflower cultivation techniques, which leads to failure. So how should broccoli be cultivated? Today the editor brings you the key points of broccoli cultivation techniques. Let's take a look below!
1. Intertillage and weeding
Intertillage and weeding is one of the important cultivation technique points in the broccoli growing process, and in the early stage of broccoli growth it should be carried out together with topdressing. First, before transplanting, water thoroughly to wet the soil, then according to the cultivated area use an appropriate amount of Lasso herbicide and spray it evenly and fully over the surface of the beds. But the soil should not be disturbed; then transplant, which can effectively suppress weed growth. During the broccoli growing process, according to the growth situation and the softness of the soil, carry out timely intertillage to improve soil permeability and promote nutrient uptake by the broccoli roots. But after the rows close, intertillage should not be carried out.
2. Timely topdressing
Broccoli growth has a relatively large demand for nutrients, and the size of the plant determines the final size of the head. So in order to ensure the head expands and to improve quality, first of all the plant must grow luxuriantly, therefore topdressing must be timely to promote plant growth. In the early growth stage and the bolting stage of broccoli, the fertilizer requirement is relatively large, so more nitrogen fertilizer should be applied, with an appropriate addition of phosphorus and potassium fertilizer, otherwise it may lead to early budding. Then in the vigorous growth period of broccoli, not only should the use of nitrogen fertilizer be ensured, but some trace elements should also be supplemented, and foliar fertilizer should be sprayed appropriately to promote the growth of leaves. Comprehensive nutrition is the key to ensuring high broccoli yield, so timely topdressing is essential.
3. Water management
Broccoli is relatively suited to growing in a moist environment, and its water demand is likewise relatively large, so during growth the soil must be kept in a moist state. Especially after flower bud differentiation, when it enters the head formation stage, the demand for water will further expand. If there is a water shortage during this period, it will affect head formation and reduce the yield and quality of broccoli. Keeping the soil moisture content at 75% is sufficient; if the moisture content is too high, it will increase the incidence of pests and diseases in the plant and cause the head to rot. Before harvest, sufficient water must be maintained, otherwise the harvested heads will be loose and deformed, reducing their commercial value.
4. Pest and disease control
Pest and disease control is a key point we must pay special attention to. We must strengthen field management, reduce field pathogens, and lower the incidence of disease. If broccoli becomes diseased, it is very easy to trigger other pests and diseases; for example, if downy mildew is not dealt with in time, it can very easily cause black mold disease. Aphids can also carry the pathogen of viral disease. No matter what pest or disease it is, the threat to broccoli plants is very great. Therefore we must inspect the vegetable garden regularly, deal with abnormal situations in time, and prepare pesticides for controlling various pests and diseases to avoid unnecessary losses.
The above is the editor's brief introduction to the key points of broccoli cultivation techniques. Although broccoli is similar to cauliflower, when growing it you cannot completely copy cauliflower growing methods. So before planting, everyone should make full preparations, such as for growing techniques, management points, and pest and disease control preparations, and so on.
