Non-pollution Yali Cultivation Management Technology

I. Soil improvement in pollution-free orchards
1. Deep-turning and soil-deepening: The deep-turning and ripening is the most basic measure for soil improvement in orchards. By deep-turning the soil, the physical and chemical properties of the soil can be improved, the activity of soil microorganisms can be promoted, the decomposition of organic matter can be accelerated, and soil degradation can be improved. The effectiveness of nutrients and nutrients promotes root growth and nutrient uptake in fruit trees.
Deep plowing and soil improvement methods: The deep plowing of the orchard is best carried out after the fruit is harvested in the autumn and before the deciduous dormancy of the pear tree combined with the autumn base fertilizer and the straw. It can also be carried out early after the soil is defrosted in early spring. The depth of deep plowing is appropriate for deeper distribution of the main root system of the fruit tree. The depth of deep plowing is generally about 60 cm. The deep-turning method can be used for deep-swapping every other year in the next year, deep-turning in the whole park, and deep-deepening in the deepening.
2, in the growing season of the ploughing pear trees, in the event of rainfall or irrigation, timely cultivator loose soil, temperature control, eliminate weeds.
3. Conditions for grass orchards and orchards covering orchards in orchards: Orchards in the orchard can be planted in the whole garden, interplanted with grass, and interplanted with grass. The orchards with deep, fertile soil and deep root distribution are all available. Garden grass. The densely planted orchard should not grow grass.
Orchard grass species: Orchard grass has certain requirements on the type of grass, its main standard is dwarf or axillary, adaptability, resistance to yin and resistance to trampling, water consumption, no common pests and diseases with pear trees, Shorter growth period. Mainly include dwarf green manure and all kinds of legumes such as legumes, such as alfalfa, sand wangwang, milk vetch, lentil scutellariae, tianjing, mung bean, pea, black bean and so on.
Orchard grass method: grass should be selected in the spring or autumn is the most suitable, you can use live or transplanting methods.
Orchard cover: It can be selected from crop stalks, various green manures or weeds, rolled 15 to 30 centimeters long, directly under the tree tray or between fruit trees, covering a thickness of about 10 centimeters. However, it is necessary to pay attention to soaking the dry crop stalks and then watering them immediately after covering or covering to prevent fire.
Second, pollution-free orchard fertilization management
1. Principles of fertilization Non-pollution orchards should be mainly applied organic fertilizer, supplemented by chemical fertilizers; base fertilizer, supplemented by top dressing, maintain and increase soil fertility, and promote the use of humic acid compound fertilizer. It is forbidden to use non-hazardous treatment of municipal waste, nitrate nitrogen fertilizer and raw materials for the production of compound fertilizer, unfamiliar human and animal manure, and fertilizer products that have not been registered.
2. Fertilization method 1 The optimum period for base fertilizer application should be after the autumn harvest of Yali pear till it is called. It can be combined with orchard deep turning to apply various organic fertilizers into the root layer of fruit trees. Applying organic fertilizer in autumn, organic matter decays for a long time and has a high degree of mineralization, which can better coordinate the heat and water heat balance in the soil and promote root absorption and growth. Accumulation of nutrients in the tree body, increase tree vigor, provide the necessary nutrients for spring flowering pear trees. The application of basal fertilizer in the spring should be as soon as possible after the early spring. Orchard uses 4 to 5 square meters of organic fertilizer per acre, and can be used together with a small amount of fertilizer. The fertilization method can be applied to a ditch or a hole, and the ditch can be used in radial, annular, strip-shaped ditch, with a width of 30-50 cm and a ditch depth of 60 cm. Fertilizer and soil were mixed and backfilled in a ratio of 1:3, and then the soil was filled.
2 Topdressing topdressing should be based on quick-acting fertilizers. Scientific soil testing and formulating fertilization should be carried out according to Yamanashi's law of fertilizer requirements, soil nutrient status, and the strength of tree vigor and yield. Generally fruity pears yield 4,000 kg of pears, 17 to 20 kg of pure nitrogen, 8 to 10 kg of phosphorus pentoxide and 18 to 22 kg of potassium oxide. According to the soil nutrient status of our city, nitrogen, phosphorus, and potassium The ratio of nutrition to nutrition is 1:0.75:0.6. That is, the annual Mushi annual Mushi pure nitrogen 14 ~ 17 kg; phosphorus pentoxide 8 ~ 10 kg; potassium oxide 6 ~ 9 kg.
The dressing is carried out three times a year. Before the budding of pears, the fertilizer is mainly made of nitrogen fertilizer, which is supplemented with phosphorus and potash fertilizers to meet the nutrients needed during flowering, increase the fruit setting rate, and promote new growth. The second time in the flowering fruit period, nitrogen and phosphorus were the main fertilizers to reduce physiological fruit loss and promote the growth of foliage. The third time during fruit enlargement, nitrogen and potassium fertilizers were used as the main fertilizer to increase nutrient accumulation in the tree to enhance stress resistance, promote flower bud differentiation, and increase yield and quality of Yali pear.
For example, if pears suffer from diseases such as yellow leaf disease and lobular disease due to the lack of certain trace elements, they should be able to determine the situation and supplement various trace element fertilizers such as zinc and iron. The application of trace element fertilizers should be mixed with organic fertilizers to increase the effectiveness of trace element fertilizers.
3 pear leaf surface dressing 4 to 5 times throughout the year, generally 2 times before, with nitrogen; 2 to 3 times in the middle and late, mainly phosphorus and potassium fertilizer, spraying a variety of trace element fertilizer. Common fertilizer spraying concentration: urea 0.3% ~ 0.5%; potassium dihydrogen phosphate 0.2% ~ 0.3%; borax 0.1% ~ 0.3%; ferrous sulfate 0.1% ~ 0.4%; zinc sulfate 0.1% ~ 0.2%.
Third, orchard irrigation
1. Principles of Orchard Irrigation The quality of irrigation water should meet the pollution-free food water quality standards of the Ministry of Agriculture. It is forbidden to use various types of sewage that are not harmlessly treated.
2. Irrigation methods combined with fertilization 3 to 4 times a year, first before flower buds germinate, the second in the fruit period, and the third in the fruit enlargement period (in this period, if the rainfall is lower than the rain, the amount of rainfall is too high. The flood prevention is also required for the large-scale flood prevention. The fourth time after pear harvesting, the basal fertilizer was applied in combination with watering. Pears were watered 20 days before harvest. Conditional pear gardens can be drip-irrigated and micro-irrigated.
