1. Land selection and soil preparation: Jujube is generally planted on sunny hillsides, plains, hills and other places, even on the roadside. 2. Scientific sowing: Before sowing, seeds need to germinate, and the germination rate before sowing should reach about 85%. At the same time, seeds need to be coated with chemicals. 3. Seedling management: After sowing 1 week, seedlings will basically emerge according to normal conditions, so it is necessary to check the emergence situation on the spot.
1. Cultivation Techniques and Yield of Jujube
1 jujube planting technology
(1) land selection and preparation
(1) Jujube planting sites can generally choose hillsides, plains, hills and other places with strong sunshine, and jujube can be planted on the roadside.
(2) The humidity in the planting area should not be too high, generally it should be dry and well drained, and it can be planted in relatively fertile loam.
③ The viscosity of soil should not be too heavy, and at the same time, the permeability of soil should be good, and it should not be desertified, otherwise it will reduce the permeability of soil.
(4) Soil preparation must be divided into Miao Di and planting areas. The soil quality in Miao Di should be fine and flat, and the soil quality in planting areas need not be too fine. Cave reclamation can be used.
(2) Scientific sowing
(1) Before sowing, the seeds must germinate, and the germination rate can reach about 85%. At the same time, seeds should be coated with chemicals.
(2) The sowing time is generally around April every year. At this time, the sowing density is about 50cm between rows and 30cm between plants, and hole sowing or drill sowing can be used.
(3) Seedling management
① After sowing 1 week, seedlings will basically emerge according to normal conditions. It is necessary to check the emergence of seedlings in the field and release them in time to ensure the safe emergence of jujube seedlings.
(2) Be sure to water properly according to the specific situation, and pull out the weeds in the field at the same time.
(3) When the seedlings grow to about 5cm, they can be thinned, and only one plant can be left in each hole.
(4) Transplanting and planting
① It can move during thinning. Generally, the seedlings will be transplanted into the ground after thinning, and all the seedlings will be transplanted when they grow to about 10cm.
(2) Generally, planting should be carried out according to the density of row spacing of 4-5 meters and plant spacing of 2-3 meters, and watering should be carried out after planting to ensure the normal growth and development of its roots.
2. Jujube yield
(1) The yield per mu of jujube is related to the age of the tree. If the tree is more than 5 years old, the yield per mu is about 2000 kg under good planting environment and management.
(2) Zizyphus jujuba is a variety of Zizyphus jujuba, also known as Sophora japonica, Zizyphus jujuba, Zizyphus jujuba and Gezhen.
Second, where is jujube suitable for planting?
1, Jujube is native to North China and distributed in central and southern provinces of China. At present, jujube can be planted in Jilin, Liaoning, Hebei, Shandong, Shaanxi, Henan, Gansu, Xinjiang, Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Yunnan and Guizhou.
2. When planting Ziziphus jujuba, it should be noted that when the Ziziphus jujuba seedlings grow to 30 cm high, the terminal buds must be removed, which can promote the growth of its lateral branches and thus increase the yield of Ziziphus jujuba. Be sure to trim and reshape the branches and leaves of Zizyphus jujuba from time to time. Generally, the crown of jujube trees should be fluffy and the permeability between branches should be better.
3. Common diseases on jujube trees are rust, scorched leaf disease and fruit shrinkage disease. Bordeaux mixture can prevent rust, Yekujing can prevent scorched leaf disease, and fungicides can prevent fruit shrinkage. There are still many pests on jujube trees, such as jujube armyworm, mites, yellow thorn moth, heart eater, borer and so on. We must do a good job in garden management, rationally use the nature of pests to kill them, or scientifically use chemicals to kill them.
