Zhanhua winter jujube seedling has strong adaptability to temperature, can withstand high temperature of 35 °C to low temperature of -10 °C, suitable for planting in tropical and subtropical regions, and can grow in temperate regions; planting evergreen fruit trees in tropical and subtropical regions, in temperate zone The area is planted as deciduous fruit trees. Jujube seedlings are of the genus Rhamnaceae in the botany taxonomy. They are of the same family as the common jujube trees in China, but different species. The jujube seedlings are the same species as the Chinese Phyllostachys pubescens, the Thai Phyllostachys pubescens, and the Chinese wild Phyllostachys pubescens. However, the varieties have different characteristics and their characteristics are also distinct.


First, cultivation techniques

    (1) Selecting seedlings

    Planting and cultivating winter jujube seedlings should choose plum seedlings with pure varieties, complete roots, strong, full buds, no quarantine objects and no pests and diseases.

    (2) Colonization

    The average plant spacing is 2.5 m × 4 m, and the buds are not planted before germination (preferably before April 20). Plums have self-infertility. Therefore, cultivars should not be single. Different varieties should be planted at a certain distance for pollination trees, with a ratio of 4:1 or 8:1.

Second, fertilizer management

    (1) Fertilization

    1, base fertilizer

    Base fertilizer is the basic fertilizer that can supply various nutrients of Lishu for a long time. It is mainly based on late-effect farmyard manure, such as compost, manure, crop straw, green manure, and fallen leaves. The base fertilizer is good for autumn, and the adult plum tree is 50-100 kg per farm.

    2, top dressing

    (1) Top dressing before flowering: 10 days before the germination of plum trees (early April), planting 0.5-1 kg of quick-acting nitrogen fertilizer or 25 kg of decomposing human excrement.

    (2) Post-flowering topdressing: The quick-acting nitrogen-potassium fertilizer should be applied in time to reduce the physiological fruit drop. In the late May to mid-June, 0.5 kg was applied.

    (3) Fruit swelling and flower bud differentiation period: Before the physiological fruit drop and before the fruit enters the rapid expansion period (from late June to mid-August), the quick-acting nitrogen, phosphorus and potassium compound fertilizers are applied, and the plant is applied 0.5-1 kg.

    (4) Topdressing in the late stage of fruit growth: topdressing during the beginning of fruit coloring to harvesting. This time, phosphorus and potassium fertilizers are the mainstays. The quick-acting nitrogen fertilizer is preferably sprayed on the foliar surface at a concentration of 0.2-0.3%, combined with spraying.

    (2) Irrigation

    Jujube seedlings need certain water in each phenological period of the year. Before germination and young fruit expansion period, the new shoot growth period should be irrigated. Before entering the winter, it is necessary to fill the frozen water once. In addition, Li Shu is afraid of cockroaches, so Li Yuanying Repair the drainage system to avoid damage.
