The taste of winter jujube is crisp, sweet and thin, and many consumers prefer it. But have we seen winter jujube trees? Is it good to manage? We must learn from these uncles about these problems, then we will look at the management techniques of winter jujube trees below.
Management Techniques of Winter Jujube Trees
First, the choice and planning of the park. Although the winter jujube is resistant to drought, phlegm, salt and alkali, it has strong adaptability to the soil. In order to achieve high-quality, high-yield and high-efficiency cultivation, it should choose to build a garden on the deep fertile micro-alkaline sand soil. The planting method of winter jujube is suitable for dense planting, which is convenient for intensive management and high efficiency. The density is 55-111 plants per 667 square meters, and the row spacing is 2-3 meters x 3-4 meters.
Second, colonization and construction. Winter jujube trees can be planted in autumn and spring. The autumn is planted in the leaves and then before the winter, and the spring planting is carried out after the soil is thawed and before the germination. When planting the branches, set the points according to the planned row spacing. According to the planting points of 1 meter square, the topsoil and the heart soil are separated. Each hole is applied with 50 kg of high-quality ring fertilizer and 0.5 kg of diammonium phosphate, and mixed with the topsoil.
Third, soil, fertilizer, water management. management. Before the planting, the land will be leveled. After planting, the soil will be ploughed, and the whole garden will be covered with grass, covering 20 cm thick wheat grass, keeping the soil moisture and adjusting the soil temperature. Fertilize. After harvesting every year, the base fertilizer is applied to the ditch. Each plant applies 50-100 kg of organic fertilizer, and 1-2 kg of multi-element fruit tree special fertilizer is added.
Fourth, timely prevention of pests and diseases. Before the germination of jujube trees, spray a 5 degree stone sulphur mixture on the whole tree to eliminate the wintering pests. In the upper, middle and lower end of May, spray the daikon-like pesticides 3000 times and add 50% of the monocrotophos 1500 times or 50%. 1500 times, control jujubes, jujube mosquitoes, jujube armyworms, blind cockroaches, leaf cockroaches, big gray worms and other pests. 6-8 months spray 1-2 times 15% broom net 2500 times or 73% gram 1000 1000 times, control leaf mites.
Five, plastic trim
1. Characteristics of winter jujube shoots. The winter jujube tree has three main buds, a secondary bud and an adventitious bud. The main bud is located in the top of the developmental branch (jujube) and in the lateral leaf axils, and the main shoot of the top of the shoot branch of the mother branch (jujube), the vitality is relatively strong. The secondary bud is located above the side of the main bud. The accessory buds in the upper part of the fertility development shoots result in the result of the branch (secondary branch), the growth of the lower part of the shoot or the result of the branch, and the resulting shoots on the mother branch sprouted the result branch (jujube). Adventitious bud: the location and time of germination are uncertain. Generally, it is developed from the thin-walled cells of the trunk and the mechanical wound of the main branch. It can germinate into a new jujube.
2. Young tree shaping. The winter jujube tree is a strong hi-light tree species, and the young tree shaping and pruning should adopt different tree shapes according to different densities. Each of the 667 square meters planted about 55 plants with a small crown sparse layer; each 667 square meters planted about 80 plants using a spindle shape; each 667 square meters planted about 100 plants with two main branches happy shape; line spacing is more than 8 meters The thin planting uses a trunk sparse layer. The densely planted winter jujube has a dry height of about 60 cm, and the thinly planted winter jujube tree has a dryness of about 1 m. According to the different structures of the trees, the method of cutting off the tops, removing the secondary branches or cutting the secondary branches by 1-2 knots is adopted. In the place where the backbone branches and the result branch group need to be cultivated, the main shoots on the base of the secondary branches or the secondary shoots are stimulated to germinate the jujube head, and the stem branches or the result branch groups are cultivated.
3. The repair of the resulting period tree. The pruning task of the winter jujube tree is to maintain a good tree structure, to distribute the branches evenly, to have good light in the canopy, and to continuously cultivate the updated branch and backbone branches to maintain a robust growth potential and a long result period. In order to achieve this goal, it is necessary to promptly remove the long branches, the competition branches, the cross branches, the dense branches, the thin branches and the diseased branches, retreat the drooping branches, and produce the first and second year of jujube on the backbone branches, according to the space. Size, leaving 3-5 secondary branches shortly cultured into the resulting branch group.
4. Summer trimming. Winter jujube trees grow vigorously, and plastic pruning should be combined with summer shearing and summer shearing. It should be based on summer shearing to facilitate early forming, high quality and high yield.
Every step of the management techniques of winter jujube trees is clear. Many farmers' uncles are now planting winter jujube trees, but the management techniques for winter jujube trees still need us to learn. If you want to grow good winter dates, you should learn the above techniques. Many people say that the most important thing about fruit is not the quality of fruit trees. In fact, the most important thing is the quality of the manager. Ok, the winter jujube tree management technology to be introduced today is here.
