Planting time and method of broccoli, sowing in autumn and listing after Spring Festival

Broccoli needs to be ploughed and weeded before planting, and enough water should be watered during planting to ensure that the soil is moist. We should reasonably water broccoli according to different growth periods. The general water content can be controlled at 70%. Too much is easy to cause the incidence of diseases and insect pests. When broccoli grows, we need to replenish nutrients in time, mainly nitrogen fertilizer, combined with a small amount of phosphorus and potassium fertilizer, and we also need to strengthen field management in the later stage. Do a good job in the prevention and control of diseases and insect pests in advance.

1. Planting time

The normal planting season of broccoli is in autumn, usually it begins to sow in autumn, winter is the season for its growth, and it can be sold normally after the Spring Festival. The seeds begin to blossom in spring and mature around April or May, but now some techniques such as greenhouses can be used to make him plant and market in the desired season. The best planting season is autumn, September and October, when the phenology is the most suitable, and the value of grown vegetables is the highest.

2. Land preparation and planting

Broccoli needs intermediate ploughing and weeding and fertilization in the early stage of growth. First of all, enough water should be irrigated before planting to ensure that the soil is moist, and then an appropriate amount of Lasso agent should be sprayed evenly and comprehensively on the border surface. In order to restrain the growth of weeds, do not touch the soil during planting, and it is not suitable for intertillage after closure. In order to promote the absorption of nutrients from the roots of broccoli, we need timely ploughing to improve soil permeability.

3. Rational watering

Broccoli is suitable for growing in a moist soil and requires a lot of water to grow. In general, soil water content is controlled at about 75%, too much water content is easy to cause the incidence of diseases and insect pests, such as flower ball rot and other phenomena. After flower bud differentiation, entering the flower ball formation stage is the period with the greatest demand for water. If the required water is not provided in time, it will affect the formation of the flower ball, thus affecting the yield and quality. Harvesting also needs to maintain enough moisture, otherwise it will also affect its economic value, loose, deformed and so on.

4. Rational fertilization

Broccoli needs a lot of nutrients during its growth, and the bigger the plant, the bigger the bulb. First of all, we should ensure the normal growth of the plant, fertilize in time, promote its growth and flourish, in order to ensure the bulb expansion. Broccoli has a great demand for nutrients in the early growth stage and bolting period, so we mainly use nitrogen fertilizer, combined with appropriate amount of phosphorus and potassium fertilizer. In the peak growth period of broccoli, we should not only apply more nitrogen fertilizer, but also add some trace elements and appropriate amount of foliar fertilizer to ensure its comprehensive nutrition and increase the yield of broccoli.

5. Field management

In the later stage, we need to strengthen field management, do a good job in the prevention and control of diseases and insect pests in advance, and reduce the incidence. If broccoli is found to be sick, it needs to be dealt with in time, for example, downy mildew is easy to cause black mildew if not treated in time, and aphids carry viral diseases, which will affect the growth of broccoli. Therefore, we should inspect regularly, detect and deal with diseases and insect pests in time, do a good job in prevention and control ahead of time, and improve the quality and yield of broccoli.
