1. Taking root
The lower part of wild bellows is usually grown 10-15 cm below ground, 7-8 cm per year. In mid-april, roots were dug from the mountains. Roots produce the highest at 14-16 cm long. When the root is dug, the soil on the root is kept as far as possible, which is of great benefit to its operation and continued development。
2. Making beds
The herring is natively fertilized under a forest rich in decomposed and fertilized, and suitable for soil laxation. Therefore, before making a bed, the bottom fertilizer is applied, preferably with decomposition pig dung, followed by horse dung, which is applied to 75,000 kg per hectare and is pushed 20 cm below the bed。
Cultivation methods
The bed is made north and south, 100 cm wide, opening a 12 cm gutter along the 15 cm line with the bed, placing the root of the beryllium in the gutter, burying it on the ground floor and laying it down. Because of the fertilization of herbs and the habit of growing obscenity under the forest, the roots are then covered with straw to keep the shade wet and, finally, with a net that is 120 cm wide。
4. Field management
After planting and during harvesting, water is often sprayed, the soil is always humid, especially in dry spring areas, and more attention is paid to bed spraying. The summer spasms fall behind to keep the soil wet so that the spores grow。
The prowl of the year has rotted, and the following spring has to be resurfaced, with water being sprayed at the beginning of april each year to promote early growth。
Lighting is an important factor in the growth and development of cabbage. The light is too strong, the cell stretch is blocked, the leaf handles are small and the food value is low; when the light light is weak, the leaves are light green, the light co-operation is poor, the photocolumn is insufficient and of poor quality. The appropriate light strength is 10,000-13000. Therefore, in field management, light intensity is adjusted in due course with shadenets, depending on the changes in sunlight and the weather. High productivity can also be achieved through the time-frame of curtains in greenhouses。
5. Protected production of beryllium
In order to increase the value of the herring's products and increase income, it is also possible to produce anti-season vegetables. Following the above method, beryllium is produced in greenhouses, plastic sheds are withheld in protected areas before the land is frozen, and can be marketed during the new year and spring festival, taking over the market and adding value。
