How do you plant it? The editor will tell you about the cultivation, management and harvesting techniques of cowhide vegetables.

Cowhide vegetable, also known as thick skin vegetable, is a long-day crop and likes warm and humid climate. the suitable temperature for growth is 15 Murray 25 ℃, which requires more water. under the condition of high soil temperature and air temperature, it can grow rapidly, soft and adaptable, and can grow in all kinds of soil. Salt-alkali tolerance. Calf vegetable has higher requirements for water and fertilizer, and likes fertile soil with good drainage and irrigation. Under the condition of sufficient nitrogen fertilizer, it can greatly increase the yield of fresh leaves. Its growth period is more than 200 days, utilization period is more than 100 days, fast growth, strong regeneration and high yield.

Cowhide vegetables should not be continuous cropping, should be rotation, suitable before as melons, legumes and cereals. The root system of calf vegetable is weak, which requires the soil to be loose, rake and level the ground before sowing, and apply sufficient base fertilizer.

Sowing time

Spring sowing is dominant in the north and autumn sowing is dominant in the south. Take Shandong as an example: sowing usually begins in the first and middle of April.

Sowing mode

In order to improve the germination rate, soaking seeds can be carried out before direct seeding. After soaking seeds in 50-55 °C warm water for 30 minutes, soaking them in cold water for 24 hours, taking them out to dry, the seeds can be sowed. There are two planting methods: direct seeding and seedling transplanting. Direct seeding can be strip-seeded or on-demand, the row spacing is about 30 cm, the soil cover is 23 cm, the sowing rate is 1.5 ml per 15 ha, and the seedling transplanting can be carried out at the height of 15 mi mi 20 cm. In order to improve the germination rate, the seeds can be soaked before direct seeding. After soaking the seeds in warm water for 30 minutes, soaking them in cold water for 24 hours, taking them out and drying them, the seeds can be sowed.

Field management

After the emergence of cowhide, there are 3 true leaves of 2 murmurs and 1 time seedling, and 4 of them are fixed seedlings with 6 leaves, and the distance between plants is 20 Mel and 30 cm. Irrigation should be carried out in time in case of drought during the growing period, and Rain Water should pay attention to drainage in summer to prevent waterlogging, weed and loosen the soil in time, and apply 400,500kg of human feces and urine or 8-10kg of available nitrogen fertilizer per mu.

Disease

The common diseases of cowhide vegetables are brown spot and leaf spot, which can be controlled by carbendazim or Bordeaux solution. It is necessary to use scientific medicine to prevent and control insect pests.

Harvest

It can be used for leaf stripping 30-40 days after planting, with 3-5 leaves per plant and 4-5 leaves left to continue to grow. The number of peeling leaves is determined according to the season and growth situation. When the growth is fast from June to July, it can be harvested 4 times and 5 times, and the yield of fresh leaves per 667m2 is more than 4000kg.

Cowhide vegetable has high nutrition and has a wide range of uses. It can be said that it is a high-quality vegetable. You can choose to plant it.
