I. Introduction to Hei Hu
1. Where is the main producing area of Hei Hu?
Hei Hu is mainly distributed in Jiangxi, Fujian, Hunan, Guangdong, Guangxi, Sichuan, Guizhou and Yunnan in China.
2. Does Hei Hu mainly have the medicinal value of rest?
Hei Hu's root can be used as medicine, which has the effects of promoting blood circulation, relieving swelling and pain, treating gastropathy, rheumatic bone pain, traumatic injury, blood stasis pain and gynecological diseases.
3. What are the planting conditions in Hei Hu?
I like growing in sparse forests in mountainous areas. Generally, wild Hei Hu can be found in forests at an altitude of 1500-2000m.
Second, how old is Hei Hu?
It depends on whether you buy Hei Hu seeds or plants. If Hei Hu plants are sold in the market, they will generally bear fruit in the second year of planting, and there will be a certain yield in the third year. In the fourth year, they have entered the full fruit stage. If you buy seeds for planting, it usually takes 2-3 years to bear fruit, which will be a little later than the purchased plants. During the high-yield period in Hei Hu, each plant can produce about 30 fruits, with a yield of several thousand kilograms per mu. Black tiger is late-maturing and resistant to storage and transportation. It can be left on the tree until it is listed out of season around the Spring Festival, or it can be picked and stored naturally until it is listed in February-April of the following year, which is of high value.
Third, introduce Hei Hu planting technology!
1. Choose land to build a garden
Hei Hu has low requirements for soil, and some common fruits can grow and bear fruit in the soil. Hei Hu is a shade-loving fruit, so it doesn't need too much light for too long, so the orchard is built on the sunny slope, or shading measures are taken. It should be noted that the plants in Hei Hu are climbing vines, so when building the garden, scaffolding should be set up in the garden to let the branches of the plants climb.
2. Soil preparation
After the planting site is selected, soil preparation, soil preparation, intertillage and base fertilizer application are carried out together. The amount of base fertilizer depends on the planting area, generally 6000 kg per mu. Deep ploughing of not less than 30cm will make the soil soft. In winter or summer, the weather can kill germs in the soil, reduce pathogens and reduce the incidence.
3. Rational planting
There are many fibrous roots in Hei Hu, so shallow planting can be used, and the planting hole is about 45-50 cm deep. The planting method in Hei Hu is similar to that of grapes, but its growth ability is not as strong as that of grapes. We should try our best to expand the planting density. When planting, apply a proper amount of base fertilizer at the bottom of the planting hole or bury it in the planting hole after being fully mixed with soil.
4. Planting time
The planting time in Hei Hu is generally in winter and spring, but the most suitable planting time is around beginning of spring, because there is more rain in early spring, which is beneficial to the growth of seedlings and improves the survival rate of seedlings.
Breeding techniques in Hei Hu
5. Water and fertilizer management
There is a great demand for water and fertilizer during the growth of Hei Hu. Because Hei Hu grows faster, the consumption of water and fertilizer will be faster. It is necessary to water and fertilize regularly to ensure that there is enough water and fertilizer at some important stages such as fruit expansion period in Hei Hu.
The above five points are the key points of planting technology in Hei Hu.
Summary: The above contents are about the achievements and planting techniques in Hei Hu for several years, hoping to help friends in need. This paper synthesizes the Internet.
