Zhanhua Dongzao is a unique rare fruit in Zhanhua County of Shandong Province. Zhanhua Dongzao is famous both at home and abroad for its rich nutrition and excellent taste quality. Jiang Yuxiang, vice president of Zhanhua Dongzao High-end Product Research Association, said that at present, 500,000 mu of Zhanhua winter jujube grows well and its quality is excellent. It is estimated that the total output of Zhanhua winter jujube will reach 700 million kilograms this year. Compared with the previous year's increase in output, prices will decline slightly. However, some problems in the current development of the Zhanhua Dongzao industry still need to continue to be solved, and they need to attract the attention of the farmers.
The first is diazo phosphorus and light potassium fertilizer. The habit of fertilizing the dates for local farmers is usually diammonium plus urea, with no emphasis on the application of potash. Potassium is the nutrient element necessary for the high yield and quality of winter jujube, and it is closely related to the disease resistance and fruit quality of winter jujube. Lack of trace elements in soil, organic content is insufficient. Although the winter jujube output has increased year after year, the quality has declined year by year. This has a direct relationship with the current people's concept of fertilization. To solve this fertilization method, first of all, the jujube farmers must change their concepts, the concept does not change, and the synergies are limited; ideas cannot be liberated and can never keep up.
Second, there is still a phenomenon of hormones and fruit preservation, and the use of high-quality foliar fertilizers is regarded as a deterrent.
Third, in recent years, the juvenile farmers mistakenly believed that the more green the more resistant to storage, "green" sale and storage, resulting in less than 10% of the total sugar of winter dates, affecting the taste and food value of winter jujube, thus causing impact on the winter jujube brand.
Fourthly, there is still a certain gap between the standardization of pollution-free production distances. Diseases and insect pests are extremely serious after cultivation of large areas of winter jujube, and there is still a certain gap between pest control technology and pollution-free production requirements. Fertilizer use is not standardized and cannot be balanced. Fertilization methods should be based on the combination of organic fertilizer and inorganic fertilizer as the main method, targeted application of trace element fertilizer.
Jujube water and fertilizer management
The jujube has the characteristics of late sprouting and early deciduous shoots. It usually sprouts in mid-April and the jujube grows. The first branch of the jujube head lasts for a long period from mid-May to late June, and basically stops growing in late July. The growth period is 50-90 days. After germination, the growth of the main buds at the top of the jujube stocks stopped after 1-2 mm, and the sprouts on the top of the jujube buds formed a hanging jujube. The jujube crane began to grow slowly and reached its peak in mid-May. After flowering, the growth slowed down, and it stopped growing until mid-June. The growth period of the leaf jujube was 50-60 days. The fallen leaves begin to fall in mid-to late October.
Before the planting, the land was leveled, and after planting, the soil was cultivated and irrigated. The entire garden was covered with grass, covered with 20 cm thick wheat straw, keeping the soil moisture and regulating the soil temperature.
Fertilization. After harvesting, the ditch is applied to basal fertilizer every year, and 50-100 kilograms of organic fertilizer is applied per acre. Phosphate-nitrogen-compound fertilizer produced by Tianji Group can meet the nutrients required for winter jujube, and it can also be used as a special fertilizer for multi-element fruit trees. 2KG. The dressing is carried out three times a year. Before the budding in early April, each crop is topped with 0.5-1.0 kg of urea or 0.3-0.7 kg of diammonium phosphate, or 80 kg of phosphorus nitrate per acre of the day ridge. In early June, the fruit fertilizer is chased. Urea 0.5-1.0 kilograms or two pods per mu (15-15-15) compound fertilizer; early in August, chase fruits and enlarge fertilizer, chase Tianji (16-6-20) high nitrogen and potassium compound fertilizers per mu. , Fertilizer can be multi-hole or ditch application, depth 10-15 cm, depending on the size of the tree and the result of the amount of fertilizer, Tianji compound fertilizer can also be used to spread the method to save manpower. Fertilizer spraying, from May to July, spray 0.3-0.4% urea or light and micro-fertilizer once every 15 days, and spray 0.3% urea and 0.2% borax mixture once during the fruiting and fruit setting period in the middle of June. 8 - Spray 0.3% potassium dihydrogen phosphate 3-4 times in September. A 0.5-1% urea spray immediately after harvesting can effectively delay leaf senescence, increase photosynthetic capacity, and facilitate nutrient accumulation. At this time, it is best to apply Tianji (15-15-15) compound fertilizer to achieve root growth. the goal of.
Irrigation and drainage. To seize the key water three times a year, that is, sprouting water, water before flowering, young fruit inflated water, to drench appropriate. When the water accumulated during the rainy season, it was drained and flooded.
Pruning
Winter date branch bud characteristics. There are three kinds of jujube trees: main buds, accessory buds and adventitious buds. The main bud is located at the top of the development branch (Zaotou) and the lateral leaf bud, and the main bud at the top of the development branch at the top of the resulting mother branch (jujube) has more vitality. The accessory bud is located on the side of the main bud. The buds of the upper part of the reproductive development sprout into the resulting base branch (secondary branch), the lower part of the reproductive branch or the resulting base branch, and the resulting secondary bud on the parent branch germinates and produces the branch (date hanging). Adventitious buds: that is, the location and time of germination are uncertain, generally at the mechanical wounds of trunk and main branches, developed from ray parenchyma cells, which can be germinated into new dates. Adventitious buds play an important role in renewal pruning. The function of the main bud of winter jujube is to sprout the jujube head and form the skeleton of the tree or the result branch. Pruning is to stimulate the germination of the main buds, to cultivate the stems and the resulting sticks.
Sapling shaping. The jujube tree is a tree species with strong joy. The pruning and sapling of young trees should adopt different tree shapes according to different densities. About 55 strains per 667 square meters are planted with sparse layer.
