The planting method of "vegetable Queen" broccoli

Broccoli is known as the "vegetable queen", is a famous health vegetable, rich in nutritional value, suitable for young and old, rich economic value, high income per mu. So, what are the methods of growing broccoli? Let's get to know it together.

First, sowing time

The most suitable temperature for the growth of broccoli is between 5 degrees and 25 degrees, so according to the suitable temperature for the growth of broccoli, generally sowing time is in spring and autumn, and broccoli is not resistant to drought or waterlogging, so we must pay more attention to management when watering. 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 grown well in winter, and broccoli grown in winter can be put on the market during the Spring Festival. At that time, there were fewer fresh vegetables, just to make up for the gap in the market, and the price was higher than usual, bringing rich economic benefits.

2. Soil preparation and seedling cultivation

Broccoli is a kind of soil planted in fertile soil, loose soil and good soil water retention. The demand for fertilizer for the growth of broccoli is relatively large, so it must be fully applied when applying base fertilizer. Only in this way can we ensure that broccoli grows better. In terms of quality selection, it is recommended to select those varieties with good disease resistance and cold tolerance, and the temperature of seed germination is about 20 degrees.

III. Colonization

Wait until the seedlings grow 5 true leaves, you can transplant, pay attention to the distance between each plant, probably around the 35cm, you can cover the ground with a film, which can control water distribution, can also increase the land temperature, planting after half a month, will begin the first topdressing, wait until the bud time for the second topdressing. If it is planted in the greenhouse, we must pay attention to maintain a good temperature during this period, neither too high nor too low. If the temperature is higher than 24 degrees, the quality of the bouquet is not very good. If it is lower than 8 degrees, growth will enter a very slow period.

IV. Disease prevention and control

When growing broccoli, you must pay attention to prevent diseases. Broccoli is prone to cabbage bugs and aphids. Medications should be used when they first appear, but it should be noted that they can no longer be used half a month before harvest.

V. Harvest

It is better to harvest broccoli when the flower bulb at the top of the plant is fully expanded and the bud is not yet open. It is easy to cause loose bulbs and blossom after late harvest. When harvested, the lower part of the flower bulb with the stem is cut off together. After the top corm is harvested, the axillary buds of the plant sprout and grow rapidly, and the lateral bouquet is formed at the top of the dry lateral branch. When the lateral bulb grows to a certain size and the flower buds have not yet opened, it can be harvested again. So broccoli can be harvested 2-3 times in a row.
