There are many uses for kraft, which can be used for feed feeding, people to eat, etc., which has the functions of clearing away heat and detoxifying and stopping bleeding. So what is the ketchup? How to grow it? Xiaobian told everyone about the cultivation management and harvesting techniques of kraft.
The kale is also called thick-skinned vegetables. It is a long-day crop. It enjoys a warm and humid climate. The suitable temperature for growth is 15--25 °C. It requires more water. Under the conditions of high soil temperature and high air temperature, it grows rapidly and texture. It is soft and adaptable. It can grow in various soils and is resistant to salt and alkali. The kraft has higher requirements on water and fertilizer, and it is good for fertile soil with good irrigation and drainage. Under the condition of sufficient nitrogen fertilizer, the yield of fresh leaves can be greatly improved. Its growth period is more than 200 days, the utilization period is more than 100 days, the growth is fast, the regeneration is strong, and the yield is high.
Cowhide should not be used continuously, should be rotated, suitable as a melon, beans and cereals. The root system of kumquat is weakly developed, and the soil is required to be loose. Before the sowing, the ground should be smashed and leveled, and the base fertilizer should be applied.
Sowing time
The northern region is dominated by spring sowing, while the southern region is dominated by autumn sowing. Take Shandong as an example: Generally, planting begins in mid-April.
Seeding method
In order to improve the germination rate, soaking seeds can be carried out before the live broadcast. After soaking for 30 minutes with 50-55 ° C warm water, soak for 24 hours in cold water, remove and dry, and then sow. There are two kinds of planting methods: live seeding and seedling transplanting. The live broadcast can be broadcast or on-demand, with a line spacing of about 30 cm, covering the soil with 23 cm, and the seeding rate is 1.5--2 kg per 1/15 hectare. The seedling transplanting can be carried out at a seedling height of 15-20 cm. In order to improve the germination rate, soaking seeds can be carried out before the live broadcast. Soak them in 50--55 °C warm water for 30 minutes, then soak them in cold water for 24 hours, remove them and dry them, and then sow them.
Field management
After the emergence of the kraft, 2 to 3 true leaves were seeded once, and 4-6 leaves were fixed, and the plant spacing was 20-30 cm. In the growing season, it is necessary to irrigate in time. In the summer, rain should pay attention to drainage and prevent guilt. It is necessary to weed and loosen the soil in time, and apply 400-500 kg of manure per acre or 8-10 kg of quick-acting nitrogen fertilizer.
Disease
The common diseases of kraft are brown spot and leaf spot, which can be controlled by carbendazim or Bordeaux mixture. It is found that pests should be controlled by scientific drugs.
Harvest
After 30 to 40 days of krafting, the leaves can be used for stripping, and each plant is stripped of 3 to 5 pieces each time, leaving 4 to 5 pieces to continue to grow. According to the season and growth conditions, the number of peeling leaves is determined. When growing from June to July, it can be harvested 4 to 5 times, and more than 4000 kg of fresh leaves per 667 m2.
The kale has high nutrition and is widely used. It can be said that it is a fine variety of vegetables. You can choose to plant it!
