The planting depth should be flush with the root neck, backfilling is practical, the seedlings should be righted and irrigated immediately after planting. When planting, the roots of seedlings are dipped in phosphate mud, which is beneficial to survival. In order to promote early fruiting and early harvest of jujube trees, it is necessary to strengthen the management of soil, fertilizer and water.
In Hexi irrigation area, except winter irrigation, the irrigation frequency is the same as that of wheat; Fertilize 0. 1.5-0.25 kg diammonium phosphate per plant, and choose reasonable crops to facilitate ventilation and light transmission; Leave enough trees to ensure the nutritional area, dry them in time after planting, and pay attention to pruning.
Extended data:
Plastic trimming
After planting, it is necessary to carry out fixed drying. The fixed drying height of jujube orchard is 1 m, and the fixed drying height of jujube-grain intercropping is1.5 m.
Pruning is done in winter and spring. In the first three years, light pruning should be given priority to, combining promotion with control, leaving more branches and becoming crowns as soon as possible. At the same time, actively cultivate high-yield trees. There are mainly trunk evacuation layered shape, multi-branch natural round head shape and open heart shape
Results When pruning trees, we should control the long branches, keep the normal branches and cut off the diseased dead branches. Give priority to with short cut, remove diseased branches, dead branches, overlapping branches and upright branches, control overgrown branches and renew old branches. Pruning in summer adopts methods such as removing core, thinning branches, removing sprouting tillers and adjusting branch position. Adjust the distribution of nutrients and realize ventilation and light transmission of the crown.
