Luzhou jujube fruit surface is bright red, the fruit of a medium size, in the sun's exposure it is so shiny, so bright and eye-catching, such as a string of grapes hanging branches, crispy jujube jujube crisp, juicy, Shaped like a mango sweet and dense, red if the chicken blood brittle pear, this is a true evaluation of it in recent years, Weizhou crisp jujube has a strong cold, drought, resistance to barren characteristics, whether in such a barren mountain On the stone slope, or in the wasteland of limestone cracks, as long as there is a little space, it can stubbornly grow. With normal results, it is no wonder that the local people call it a cash cow. Overall, there are several advantages. The first advantage is of relatively good quality. When it has a high sugar content, it can reach 30%. It is very sweet and brittle. Therefore, the quality is excellent, and the second is the weak tolerance. We are now The environment we see is entirely mountainous. It can grow well in places with many soil and stones. The third characteristic is that it has a strong early fruit and it will be grafted this year and girdled next year. It will be the result next year. In fact, the crisp jujube in Quzhou is not difficult to plant. As long as we master the grafting technology, even if it is grafted in the shacks, it can thrive. The quality of rootstock and scion is directly related to the survival rate of grafting. The results sooner or later, how much and quality. Prior to grafting, the preserved jujube branches were cut into small pieces, leaving 1-2 main shoots in each stage. In order to reduce the evaporation of water in the scion and improve the survival rate of grafting, the scion was applied to the scion, and the key technology was used when wax sealing. It is to grasp the wax seal temperature and waxing time, the temperature is too high is easy to scal scion, the temperature is too low, the wax layer is too thick, easy to peel off, here is a trick to melt the paraffin before the bottom of the pot to add some water to ensure the temperature No more than 100 degrees, the grafting time is generally before and after sprouting of wild jujube seedlings. The methods of grafting are various, and the method of grafting is more commonly used in production. Before the grafting, the anvil is flated. The height of the flat anvil is 8-10 cm. The cut jujube branches are removed. The lower end of the scion used for cutting is cut into two equal lengths. The length of the cut surface is 2-3 cm. The straight surface is required. When the graft is in the grafting process, the smooth and smooth part of the rootstock of the rootstock is cut flat, and the scissor is cut open in the central part of the rootstock. The scion is inserted to align the sides and the buds are aligned on this side. On the other hand, the management of grafted seedlings is relatively simple, and the management of grafted seedlings is relatively simple. There is a key link in the sprouting stage of grafted seedlings, that is, timely removal of sprouting, that is, removal of buds sprouted from rootstocks in order to focus on nutrition promotion interfaces. Healing and scion growth, generally in addition to the number of Meng Meng not less than 2-3 times, these are in addition to the sprouting sprouts grow out of the new shoots, if managed well, it will swiftly grow, one by one, if managed properly, then Can be more than 1 meter tall. People often say that smashing dates, eating melon to eat smashed, eating dates to eat cracked, said that splitting the sugar content of dates, in fact, otherwise, if the jujube tree is relatively early drought, more late rain, its flesh and peel The unbalanced growth, that is, the flesh is growing fast, and the peel is slow, then how should we solve it? The clever people of Jixian County, in order to make the jujube fruitless, they took materials from the local orchards in the mountains. In the early stage of drought, when the fruit matured and there was a lack of rain, the weeds were cut off and then covered under a tree. This not only prevented the evaporation of water, maintained the relative stability of the soil moisture, but also reduced the cracking fruit, which facilitated the growth of the jujube and the weeds rotted. After that, it will be a very good fertilizer in the coming year. It will not only prevent fruit cracking but also fertilize fertility. Then how should the planting be done in a reasonable place? How do you look at the density? If there is less land, in the long run, you can The first is dense, and the latter is rare. It can also be sparsely planted. If it is too thin, ringing should not be too early. The girdling is carried out at the flowering stage, mainly to injure the phloem of the tree. If it is not circumcision, the organic matter produced by the photosynthesis of the jujube tree will be transported under the tree. After the girdling, it will cause temporary trees. Accumulation of nutrients allows more organic matter to be distributed to the flowers and fruits of the upper shoots to increase yield and quality. The girdling should be carried out on a sunny day. The jujube brittle jujube will be planted this year and will be girdled in the next year. The girdling will be able to receive dates in the year. The width of the girdling is one-tenth of the circumference of the trunk, 15-20 cm from the ground. It is advisable to gird up in succession each year. The degree of girdling is best when the knife edge reaches the xylem. Peel the phloem. Although this cultivar is a very drought-resistant cultivar, it is best to pour it for a year if it is irrigated. 2-3 times of water, if there is no such condition, it can be adapted to local conditions. One is pouring water once before flowering, mainly to promote the growth of new shoots. It is very favorable for the later fruiting, the second time the water is after flowering, the fruit is long-term, The increase in fruit is very beneficial. Three times is frozen water, which is the last time in the year. It is safe for the seedlings to overwinter and it is very beneficial to the tree's water storage. In addition to pouring enough water before freezing, it is also necessary to apply some organic fertilizer. During fertilization, the depth of the digging hole is 40 cm, the width of the hole is 40 cm, and the length of the hole is about 100 cm. When fertilizing, appropriate soil should be added and mixed to avoid mixing. Fertility is too concentrated and damages the roots of jujube trees. Watering should be done promptly after application of fertilizer. Jujube is rich in nutrients and trace elements, and has unique nutritional and medicinal value. Jujube also has the effect of strengthening spleen and nourishing the stomach and nourishing blood. As the saying goes, one party raises one’s land and water and raises one person’s age. They are similar to each other year after year, and they are very fruitful. The people who accompanied it with the cruciferous jujube of Cangzhou passed through generation after generation. It also made the people there go out of poverty and move toward being rich. The cultivation of the state's crisp jujube can also achieve ecological benefits such as greening of the mountains, soil and water conservation, wind and sand fixation, and expansion of vegetation.
