The most New Zealand Flower planting techniques and methods course

Although broccoli is a kind of exotic vegetable, the market demand in our country is still relatively large. Broccoli is very rich in nutrients, and nutrients are also very comprehensive, its content is higher than most vegetables, especially vitamin C content, is the highest in all vegetables. So how to grow broccoli? The following editor brings you the planting technology of broccoli, let's have a look!

1. Prepare the seedbed

The seedbed should be ready about 4 days before broccoli seeds are sown. Do a good job of disinfecting the seedbed, sprinkle the seedbed with methyl topiramate and other agents, then apply sufficient farm fertilizer, fine rake the soil, and fully mix the fertilizer with the soil. If it is a newly developed planting site, it is best to sprinkle some nutritious soil to improve the soil fertility. But also to ensure that there is sufficient light, suitable temperature. The most important thing is to have enough clean water to provide sufficient water for broccoli during planting.

2. Sowing and raising seedlings

Before sowing, the seeds of broccoli should be disinfected and germinated, and seeds should be mixed with thiram and other agents to eliminate germs. Then soak the seeds in warm water for about 3 hours, and the water level should be sure to submerge the left and right seeds. Then put it in the environment of about 22 degrees to promote germination, when most of the seeds are white, they can be sown. When sowing, we should pay attention to control the planting density, and it is appropriate to cover the soil with invisible seeds after sowing. Finally, we should cover the soil with plastic film to improve the heat preservation ability of the soil and promote seed germination.

3. Transplanting and planting

Before the seedlings emerge, the temperature should be controlled at about 23 degrees during the day and not lower than 13 degrees at night. Then, when the broccoli seedlings are unearthed, the seedling management can be done well, and when the seedlings grow about 5 true leaves, they can be planted within one month. First of all, it is necessary to prepare the field, remove the residual branches and weeds of the previous crops in the field in time, and carry out soil preparation and fertilization. Sufficient water should be watered before transplanting to prevent root injury and control the planting density. After planting, compact the surrounding soil and irrigate the root water again.

4. Water and fertilizer management

The topdressing of broccoli should be done within 2-3 weeks after planting, and urea is the main fertilizer. Should pay attention to control the dosage, not too much too little, too little can not meet the growth and nutrition, too much is easy to cause broccoli fertilizer damage. The nutritional demand of broccoli is very large, we also need to control the proportion of nutrition, in which the largest demand for nitrogen fertilizer, phosphorus and potassium, but also pay attention to the supplement of boron, magnesium and other trace elements. The water demand of broccoli is also very large, especially in the important periods such as the heading period of broccoli, it is necessary to keep the soil moist at all times. But water should not be too much, if too much water in the seedling stage, it is easy to cause broccoli diseases and insect pests.

In the process of planting, controlling the soil water content at about 75% is the most suitable humidity range for broccoli growth. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
