How is broccoli grown? Cauliflower is actually the broccoli that we usually call. The nutritional value of broccoli is well known, so the farmers who plant broccoli are now more than before. Today, let's learn how to achieve high yields of nutritious and healthy broccoli.
First, the cultivation season
Cauliflower can be cultivated in spring and autumn. Spring is usually in the middle and late January, and the seedling period is 50 days to 60 days. In the middle and late March, the open field will be planted. In the middle and late May, it can be Harvested. If it is planted in autumn, it is usually planted in mid-July in mid-July. The open field is planted in early August and harvested in mid-to-late October.
2. Land preparation, fertilization and colonization
The growth trend of broccoli is very strong, so the amount of fertilizer required is also very large, and the farmers must apply the base fertilizer together with the soil preparation. Under normal circumstances, a high-quality ring fertilizer of 5,000 kg per mu, 30 to 40 kg of superphosphate, 50 kg of grass ash, 5,000-1000 kg of decomposed dry manure.
After the base fertilizer is applied, it should be deep-plowed and then flattened to make a 1.3~1.5m wide flat. When the broccoli seedlings have 5~6 true leaves, they should be planted. Generally speaking, two rows per acre are planted, the plant spacing is 30~40cm, and the planting density is about 2500 per acre. If it is a precocious variety, the density can be appropriately increased, and about 3,000 plants per mu are suitable.
Third, fertilizer management
Cauliflower is good for fat, so timely topdressing is the key, of course, watering is also very important. The topdressing is mainly based on nitrogen fertilizer. When entering the formation stage of the flower ball, it is necessary to increase the application of potassium fertilizer and phosphate fertilizer.
The top flower ball and the side flower ball of broccoli can be harvested several times, but after each harvest, it is necessary to topdress in time to promote the growth of the side flower ball.
Cauliflower requires a lot of water, and both the rosette and the flower formation period need sufficient water. Everyone remembers to water in time. However, if it is in a rainy area, it is necessary to drain it in time to prevent roots and roots.
Fourth, harvest
When the broccoli is fully inflated, the buds are best picked when they are not yet open. Picking should not be too early or too late. Picking techniques, the lower part of the flower ball can be cut with a flower stem about ten centimeters.
The above is the high-yield cultivation method of broccoli. You can see if there is any place you can use. If you have other places you want to know or would like to share, you can leave a message directly under Hui Nong.
