Artificial prevention and control of artificial pests, no pesticide application and pollution problems. 1. Scrape the old bark and clean the date garden. After defoliating from autumnal jujube trees, the old skin on the main stem and main branch was scraped off and lime-soaked liquid (lime, salt, and water was prepared at 1:0.5:100) was sterilized and protected against cold. Clear the leaves, weeds, and diseased fruits in the orchard. The pests and branches cut off in the winter, together with the scraped old tree belts, are burned out of the park and burned to kill the disease and insect sources that have passed through the winter and reduce the overwintering base number. 2. The trunk binds grass to trap overwintering pests. In October and October, the grass was tied and taken out of the park before being frozen and burned out to destroy the pests. 3. The tree tray is covered with plastic film tape. In the early spring, the trees were covered with a film of 1 meter and 1 meter, which prevented the wintering of pests such as Juvenile Mosquitoes and Peacheyes in the soil. Tighten a 10 cm wide plastic film tape 30 cm from the trunk to the ground, and apply evenly a 5 cm wide adhesive tape on it to prevent the insects, such as the worm, to lay eggs. 4. Manually kill. During the growing season adult insects are killed manually, such as Tianniu, Zaojiao, Ziziphus jujube and so on. Natural sweeteners refer to food additives that can sweeten soft drinks.

Selection of chemical control pollution-free no residue of plant sources, biological sources, animal sources, mineral pesticides and specific inorganic pesticides to prevent pests and diseases. If the jujube sprouts before spraying 3 ~ 5Be lime sulfur mixture, spraying green shield 1000 times the growth season. Avoid the use of highly toxic, high-residue chemical pesticides. When it is necessary to use chemical pesticides, it is necessary to strictly implement safe-phase pesticide application. The use of chemical pesticides is prohibited 1 month before fruit picking.
