4. Tossing tree trays and soil preparations: Before soil freezing or in early spring soil thawing, deepen the tree tray by 20 cm, raise the height of the wall, and simultaneously maggots, insects, larvae, adults, etc. to facilitate soil maturation, water storage, and conservation. Keep water and soil to reduce the density of overwintering insects.
5. Plastic skirt, spray lime sulfur mixture, spray diesel emulsion. In late February, a plastic skirt was put on the trunk to stop the females from juveniles from jujube, and the females were caught in the early morning. In the middle and late March, 3-5 Baume degree lime sulfur was sprayed to prevent and cure the red spider, jujube leaf, etc. Insect pests, jujube turtle wax scorpion serious, spray 10% -15% diesel emulsion.
6. Jujube planting: Choose 2 years without pests, robust jujube seedlings, planting with the seedlings, watering after planting, soil conservation.
