Management techniques of Jujube Orchard in late Autumn and early Winter (2)
The second step is to plough the jujube orchard: implement the jujube forest with intercropping of jujube and grain, and dig deeply the soil between the plants and under the canopy. If the intercropping of jujube and grain is not carried out, the whole garden must be ploughed, especially the soil within the projected area under the canopy must be deeply ploughed. The closer to the trunk, the shallower the ploughing should be, the farther away from the trunk, the deeper the ploughing should be, generally 15 to 30 centimeters is appropriate. In this way, the overwintering pupae and eggs in the soil can be frozen to death. This management measure can reduce the damage of many pests, such as jujube inchworm, jujube moth, jujube gall midge, weevil, red spider, beetle and peach heart borer.
