The planting method of "vegetable Queen" broccoli

Broccoli is known as the queen of vegetables, is a well-known health vegetables, rich in nutritional value, suitable for all ages, rich economic value, high yield per mu. So, what are the cultivation methods of broccoli? Let's find out together!

I. Sowing time

The most suitable growth temperature for broccoli is between 5 degrees and 25 degrees, so according to the suitable temperature for broccoli growth, the general sowing time is in spring and autumn, broccoli is not drought tolerant and waterlogging tolerant, so when watering, we must pay more attention to management and control the amount of watering.

Of course, now that there is a greenhouse, many vegetables do not need to consider the season. In the greenhouse, broccoli can also be planted well in winter. Broccoli planted in winter can be listed during the Spring Festival. At that time, there are fewer fresh vegetables, which just makes up for the market vacancy. Moreover, the price is higher than usual, bringing rich economic benefits.

II. Soil preparation and seedling raising

Broccoli is a kind of planting in fertile soil, loose soil, soil water retention good soil layer, broccoli growth for fertilizer demand is relatively large, so in the application of base fertilizer must be applied enough, so as to ensure broccoli grows better, quality selection, it is recommended to choose those with better disease resistance, more cold-resistant varieties, seed germination temperature is about 20 degrees.

III. Planting

When the seedlings grow out of 5 true leaves, they can be transplanted. Pay attention to the distance between each plant, about 35cm. You can cover the ground with a film, which can control water emission and increase the temperature of the land. After planting for half a month, you should start the first topdressing. When the buds appear, you can carry out the second topdressing. If it is planted in the greenhouse, this time must pay attention to maintain a good temperature, not too high or too low, if the temperature is higher than 24 degrees, the quality of the flower ball is not very good, if it is lower than 8 degrees, the growth will enter a very slow period.

IV. Disease control

When planting broccoli, we must pay attention to preventing diseases. Broccoli is easy to appear cabbage caterpillar and aphid. We should use medicine when it just appears. It should be noted that half a month before harvest, we should not use medicine again.

V. Harvesting

Broccoli is harvested when the bulb at the top of the plant is fully expanded and the flower bud has not yet opened. It is easy to cause loose bulb and flowering when it is harvested too late. When harvesting, the lower part of the bulb with flower stem about 10 cm is cut off together. After the top bulb is harvested, the axillary bud of the plant germinates and quickly grows lateral branches. The top of the stem lateral branches forms a flower bulb, i.e., the lateral flower bulb. When the lateral flower bulb grows to a certain size and the flower bud has not yet opened, it can be harvested again. Therefore, broccoli can generally be harvested continuously for 2-3 times.
