Ningyang jujube cultivation has a long history, rich resources, high quality, welcomed by consumers at home and abroad; in order to further achieve the high quality and high efficiency of Ningyang jujube, specially formulated the following Ningyang jujube high quality and high yield technical standards:
First, soil, fertilizer and water management:
1, deep plowing expansion hole, increase organic fertilizer:
After jujube harvesting each year in the autumn, the jujube tree is deep-swapped, thickened, and trimmed. The tree-pan is expanded every year, 1/4-1/3 of the tree-pan is expanded every year. Care is taken to protect the root system from thin jujube trees with bare soil and bare roots. Cultivate soil and thicken the soil. At the same time, combined with reforming the local fertilizer, the amount of fertilizer applied is more than 100 kilograms per plant, and 1-2 kilograms of special fertilizer for fruit trees are applied. The organic fertilizer is mainly soil miscellaneous fertilizer, circulatory fertilizer, animal manure, and crop stalk.
2, top dressing:
At the same time as applying basal fertilisers, before the annual germination, the second quick-impact fertilizer is applied after the Xiehua. In the early stage, phosphorus and potash fertilizers were mainly used. 0.5-1.5 kg per plant. At the same time, spray 0.2-0.5% urea and 0.2-0.5% potassium dihydrogen phosphate, etc., more than 3 times.
3, watering After each fertilization, timely watering, the key to filling before germination, flowering, fruit expansion and frozen water, do a good job of cultivator loose soil protection. Vigorously promote the application of tree trays, grass cover, film, hole storage fertilizer and water technology.
Second, pruning jujube tree has bright light, strong polarity and other characteristics. Long-term pruning of jujube trees that are left uncultivated often results in problems such as tree-like disorder, dense branches, upright branches, unclear main side, weak upper and lower sides, poor ventilation and light transmission, causing serious damage to pests and diseases, and low fruit setting rate. The resulting parts moved outwards, and the yield and quality decreased. In the juvenile jujube gardens, spindle-shaped pruning is adopted, leaving a strong and strong central leader. The central leadership arranges 5-7 main branches on a cyclical basis, and the mature jujube trees are pruned by means of tree pruning and trimmed by branches. Generally, 5-10 stems are kept in each tree and evenly arranged in the tree body; 1-2 branches and 1-2 branching angles are taken for excessive erect and branches; for sparse and cross branches In addition to methods such as retraction, the pendulous branches and old branches are rejuvenated by retraction, and for the jujube head with space, a short cut is made to further expand the canopy.
Third, Baohuabao fruit jujube tree has a large amount of flowers, long flowering period, but the flowering and fruiting is serious. Its flowering and fruit setting needs certain air humidity and temperature, good light, sufficient nutrients and endogenous hormones and other conditions to strengthen the flowering period of jujube trees. Management and improvement of fruit setting rate are key measures to achieve high yield of jujube trees. They can be taken from the first flowering stage to the late flowering stage to spray 2-3 times of 10-15PPm gibberellin, and in the early stage of flowering, the main trunk is opened and the jujube head is topping. , spraying 0.2-0.5% borax, spray water, flowering bees and other measures.
Fourth, pest control technology:
The diseases and insect pests that endanger the county's jujube mainly include peach borer, Zaojiao, Japanese turtle wax, jujube and jujube rust. They are used to establish and improve forecasting systems, understand the rules of pests and diseases, and actively implement the principle of prevention. Comprehensive prevention and control of the plant protection policy for comprehensive prevention and control. It focuses on agriculture and physical control, advocates biological control, and scientifically uses chemical control techniques in accordance with the law of occurrence of pests and diseases to effectively control pests and diseases.
