Detailed Explanation of Key Techniques for High-Yield Cultivation of the Turnjujube Tree
Turnjujube is also called longevity fruit, wanzi pear, qiujiang zhiju, chicken-claw lian, golden-hook pear and so on. Its fruit is rich in nutritional value, and its wood is relatively good, making it a high-quality timber. So, what high-yield cultivation techniques are there for the turnjujube tree? Let us take a look together!
1. Site selection and land preparation
Turnjujube has relatively strong adaptability and generally grows in sunny and moist environments. The most suitable place for the growth and development of turnjujube is still land with fertile soil, a good drainage and irrigation system, and a moderate PH value. Because there are too many wild varieties, it has never received people's attention. With problems such as logging and environmental pollution, resources have declined rapidly and commodities are lacking, so turnjujube should be planted on a large scale. Before planting, after choosing a suitable planting area, first dig planting pits about one meter deep and one meter wide, dig sloping land into fish-scale shapes to prevent excessive soil erosion, and some dead branches and fallen leaves can be placed in the pits to serve as fertilizer for planting.
2. Raising seedlings and sowing
The main propagation method of the turnjujube tree is seed propagation. Seeds are collected every November when the turnjujube matures. The seed coat is reddish-brown. Generally, one fruit contains 3 seeds. The seeds are leathery, and the middle embryo is yellow-white. It is relatively difficult for them to absorb water, so after harvest they should be sprouted with wet sand. Each layer of seeds is stored in a layer of wet sand. Generally, radicles appear after two months, and then sowing can begin. Seedlings generally emerge in early April. When the seedlings have grown about 5 true leaves, thinning begins, keeping the strong and removing the weak. During the seedling stage, they should be watered and fertilized frequently to promote seedling growth.
3. Management after planting
Because the seedlings of the turnjujube tree grow very slowly, management of young trees must be strengthened after planting. After planting, it generally takes 5-6 years before fruiting begins. Every spring and summer, when weeds grow wildly, the soil must be loosened and weeds removed in time. In dry weather, watering should also be done in time. Fertilize once each in spring, summer, and winter every year to promote tree growth. The use of modern dwarfing and branch-pulling techniques can effectively shorten the time for the tree to bear fruit. In the second year after planting, when the small tree grows to about 1.5 meters, bend its trunk to achieve the goal of early fruiting and bearing more fruit, improving the economic benefits of planting.
4. Harvesting and processing
When turnjujube is not yet fully mature, the fruit stalk contains a large amount of tannic acid. This tannic acid affects our sense of taste, making us feel that it is sour, dry, and astringent, and difficult to eat. Every winter, after several frosts, when the fruit stalk turns reddish-brown, it represents maturity, and harvesting begins. When harvesting, cut off the fruit branches and store them in a cool area. After about a week, they can be sold on the market, or they can be squeezed into juice for sale. The main thing is still to arrange the appearance well, tie them into small bundles, and sell them to various markets, hotels, and other crowded places.
