How to manage the winter jujube tree?

How to manage the winter jujube tree? Please give guidance on the management of winter jujube trees can refer to the following methods: first, planting: it can be planted after falling leaves in autumn to before sprouting in spring. In general, there are 111 seedlings per mu with a row spacing of 23.3 meters, or planted according to a row spacing of 2cm. When planting, dig the square hole of 40-50cm, the planting depth is based on the equal position of the original soil in the seedling bed, watering after steady, covering with plastic film after water infiltration, preserving soil moisture and restraining alkali, and uncover it before the rainy season. Soaking roots with 50-100ppm rooting powder before planting can increase the survival rate by 90%. The planting row leaves a 1.5-meter-wide protective belt and cannot grow high-stem crops. Water should be watered in time during drought. Second, management: 1. Fertilize, water and loosen the soil. After survival, the young trees were fertilized in time to promote growth in the rainy season. 0.5 jin urea + 1 jin diammonium per plant was applied in 8 points, watered in drought, applied again in mid-late August, and loosened soil and weeds in time during the growing period. When base fertilizer is applied in autumn, mature trees are generally applied farm manure 50-70kg/, plus urea 1 jin and diammonium 1.5 jin per plant. The young trees were fertilized with basal fertilizer 15-25kg/. Chemical fertilizer 0.5-1 jin per plant. Dig the annular ditch with 50-60cm wide 40cm and long 60-100cm in the periphery of the vertical projection of the crown, and mix topsoil with farm manure and chemical fertilizer. Pour a lot of water after fertilization. two。 Shaping and pruning: the shape of the culture tree is natural spindle shape, cylindrical shape, small skeleton layered shape, dry height 70cm, crown height 2.5m, main branches (backbone branches) 8mur12, spiral staggered arrangement, uniform growth. Select the secondary branch with good azimuth and angle and leave 2 Mel 3 segments short to stimulate the germinated jujube head to grow into the main branch (avoid the main bud branch to act as the main branch to prevent splitting after load), and the summer shears use sprouting, heart-picking or branch thinning to ensure ventilation and light transmission. Third, protect flowers and fruits: cut around in the second year of planting, and peel around in the third year. Nail opening time: spend 40ml 60%, width 0.4-0.6cm, dry nail for 15 days after opening nail, then apply 1000 times 1605 medicine mud to control beetle. In the early flowering stage and full flowering stage, the rare earths were sprayed with 300Mel 800x, and the jujube Fengling 920x or 500x of 10-15ppm were sprayed to increase the fruit setting rate, and 10ppm NAA was sprayed at the later stage to prevent fruit drop. Fourth, control diseases and insect pests: after jujube bud germination in spring, mainly control bud-eating weevil, jujube tassel mosquito, jujube armyworm, can spray 1000 times methamidophos solution 2Mel 3 times. Attention should be paid to inspection, timely elimination and relaxation of management will cause the illusion of sprouting late. Pay attention to the harm of red spiders before and after wheat harvest. If there is any harm, 2000 times the amount of pyridaben can be sprayed. The peak period of peach heart borer damage is in early July, the end of July and the end of August, so spraying should be done in time. Pay attention to the prevention and control of jujube rust in the rainy season, which can be sprayed with 800 times triazole copper or 1500 times methyl topiramate. Fifth, fruit picking: the fruit is picked from the end of September to the middle of October, when coloring is more than 50%. It should be put in batches by stages, handled gently, with fruit stalks and stacked by stages. Cut your nails or wear thin gloves when picking.
