Orchids are also known as green flowers, cabbage, etc., as a very common vegetable, which is colourful, tastes soft, nutritionally valuable and has better prospects for growing. So when's the best broccoli growing? Let's find out。
When is the best place to grow broccoli
Orchids are cool vegetables with the best growth temperatures ranging from 15 to 21 degrees, and the best planting season is concentrated mainly in spring or autumn. Of these, planting is usually carried out in mid-march in the spring and picks in early june, while planting is usually done in the autumn in july and in mid-september。
Ii. Technical highlights of the cultivation of broccoli
1. Selection of seedbeds
The seedbeds shall be suitable for high-lying, fertile, drained sand. There is a tendency to use cabbage and cabbage. Fertilized composts of 15-20 kg per square metre before seeding open ditches at 1. 5 m clean, 40 cm wide and flat。
2. Cultivation
As in the case of broccoli and broccoli, the seeds are better dried and the growth rate is high. 20-30 grams per acre. It is generally used to sow, and once the water from the seedbed is fully seep, a thin layer is spilled over the concrete in order to prevent the seeds from adhesing into the mud, and to increase the aerobicity and yield the seed. The seed is then spread evenly on the surface, immediately after sowing, covering the sifting soil, which is 0. 5 cm thick, and then flattened with a thin membrane on the nursery bed to act as a warmer guard。
3. Replanting
When the seedlings grow 5-6 leafs and are 30-35 days old, they can be replanted. A small height of 80 centimetres for planting, 30 centimetres for cleavages and 40-50 centimetres for each row, and approximately 2,300-2700 acres for each acre。
4. Field management
The plant should be replanted in a timely manner and must be weeded in time for the medium term, in conjunction with the medium-term ploughing. The gutter is used to prepare the roots against drought and flooding, to observe carefully, to combat the pests in a timely manner and to remove the branches in a timely manner. The elimination of the thin side branches saves nutrients and provides for the growth of the main branch。
5. Collection in due time
The exact timing of the harvest is better in the morning and evening, with three to four small leaves left around the flower ball to protect the ball, the broccoli tissue is soft, the harvest and handling must be light, preferably packed in plastic baskets or boxes, not overfilled to prevent crushing。
In general, broccoli can be grown in the spring or autumn and is recommended for planting in sun-hot rooms, both for early ripening and for productive purposes。
