Winter jujube has thin, crisp, small nuclear, high sweetness and unique quality, more and more people's favor, so the market is in short supply. However, due to the improper management of the Zaoyuan, the yields and benefits are not ideal. To this end, summing up many years of experience, we will introduce an early-stage high-yield management technology that can be used to produce 300 kilograms when it was planted and 1/15 hectare (1 acre) of the year.
(I) Garden selection: The garden should be chosen from fertile land, well-drained and irrigated land, flat land, and verdant soil.
(b) Cultivation time: Suitable for autumn planting.
(c) Planting density: Plant spacing 1X2 meters, 333 per mu.
(4) Seedling selection: Choose seedlings that are 1.5 meters or more taller, more than 1.2 centimeters thick, with complete roots and no pests.
(v) Planting techniques: Dig 80cm square of the planting hole, apply enough base fertilizer, and drench the water to be planted. Before planting, roots of seedlings can be soaked with 50 mg/kg of ABT1 rooting powder for 1 hour.
(VI) Post-planting management:
1, seedlings after planting. Timely whitening. Pour frozen water before freezing and then pile 30 cm of mound on the base of the tree trunk and put grass on the trunk to prevent freezing and rabbit bites.
2. Spring management. After the soil is thawed, lift the grass handle and remove the mound 2 or 3 times to remove the mound. Use the trunk as the center to cover the 1 m square mulch to raise the ground temperature and maintain the soil moisture so as to facilitate the survival of the winter jujube tree.
3, after jujube sap flow. Pull the trunk to the line between the lines (to prevent the grafting interface from cracking, and fix the bamboo frame at the marrying interface), pull the bending angle to 120 degrees, and then remove the jujube head. At the highest point after the main bending, select a strong main bud that is built on the main trunk, cut off the secondary branch that is above the main bud, and use it as the center stem to grow, and then select the appropriate two strong points under it. After buds and secondary branches are cut off, the buds are carved at 1 cm above them, and the secondary branches below 40 cm in size are also cut off. When the secondary branches are cut off, 1 cm stakes are left and the secondary branches are cut out. Seal with wax to prevent draining and affect the growth of the main bud.
4, after the budding jujube. To eradicate buds germinating outside the center stem and the two main branches in order to save nutrients and concentrate the growth of the supply center and the two main branches. During the budding period, we must pay attention to the occurrence of pests. If there is any insect pests, we must prevent them in time.
5, foliar spray fertilizer. Due to the relatively weak root absorption capacity of the seedlings just planted, it is necessary to spray the leaves in time. After the jujube sprouts, the leaves can be sprayed once every 15 days, but it should be noted that the foliar spray fertilizer concentration should be smaller.
6, flowering management. Under the above meticulous management, the seedlings grow vigorously, the second branch of the main body is pulled and bent, and the jujube stocks have a large number of flower buds growing in the hanging leaf. In order to save the tree nutrients, it is necessary to timely sparsely flowering. When sparsely flowering, it should be sparsely jujube hanging base flowers, leaving the lower part of the flower, with each jujube hanging 1 ~ 2 inflorescence is appropriate, to promote fruit setting, in the early flowering period in the central branch of the upper ring 2 or 3 laps, Each lap is 5 to 10 cm apart. At the same time, 10 to 20 mg/kg of gibberellic acid was mixed with 0.3% borax at the first flowering stage and full flowering stage.
7, after the fruit is managed. It is necessary to carry out topping on the center stem and the two main branches so as to concentrate the nutrient supply of the growth of the jujube fruit and to prevent and treat diseases and pests in time.
