Jujube, also known as jujube. It is characterized by very high vitamin content and has the reputation of "natural vitamin pill", which has the effects of nourishing yin, strengthening yang and enriching blood. Jujube is a temperate crop with strong adaptability. Jujube is known as "hardcore crop", which has the characteristics of drought and waterlogging tolerance and is the first choice for developing water-saving forest and fruit industry.
Planting method
Dig a long, 80 cm wide and 60-80 cm deep planting pond before planting. When digging a pond, the topsoil and subsoil are stacked separately. Grass or straw is placed at the bottom of each pond. 50 kg of decomposed farmyard manure in the middle layer is mixed with topsoil and backfilled, and then the subsoil is returned to the field (preferably all topsoil). When the planting pond is backfilled, it should be 30 cm above the ground or 20 cm below the ground, and water should be injected into the soil in the pond to make it sink. When planting, dig a hole 20 ~ 30 cm deep in the planting pool, put jujube seedlings in the center of the hole, and lift them while filling the soil, which is practical. After covering the soil, the planting depth is slightly higher than the ground, which is consistent with the seedling depth of the nursery. It is not allowed to plant too deep (buried in the joint) or too shallow. After planting, a circular tree tray with the diameter of 1 m is formed around the seedlings, and the tree tray is covered with a film (the size of one square meter), which has the functions of moisturizing, warming and inhibiting weeds. When digging the pond for planting, stay wires to ensure that the seedlings reach the "three-look" line after planting.
Fertilizer and water management
After the young trees are planted, topdressing 10 ~ 15 days before germination in spring, each tree is treated with 1 ~ 2 and 10 kg of water, and then the operation is repeated every other month (irrigation topdressing), and the topdressing position is 30 ~ 40 cm away from the trunk.
Plastic trimming
After planting jujube trees, cut off roots, buds and redundant branches. When the trunk 1.2 ~ 1.5 cm thick and the secondary branch is 0.8 cm thick, the trunk shall be cut off at a distance of 60 ~ 80 cm from the ground, and the primary secondary branch below the section. Three suitable secondary branches 1 buds were selected for short cutting to promote the formation of primary lateral branches.
interplant
You can't interplant crops with high stalks or high soil consumption, such as corn and potatoes. You can interplant leguminous crops, preferably green manure, to make up for the shortage of farm manure, and at the same time, you can inhibit weeds and cover the ground.
plant diseases and insect pests
There are many kinds of diseases and insect pests on jujube trees, which are widely distributed and seriously harmful, which is an important reason for the low yield and poor quality of jujube trees. At present, the serious pests and diseases mainly include jujube step, jujube armyworm, peach fruit borer, bud weevil, jujube witches' broom, jujube rust and so on. Adhere to comprehensive pollution-free prevention and control measures focusing on prevention in prevention and control. In order to effectively control the occurrence and harm of pests and diseases!
