Orchard Planning and Planting Technology
1. Orchard planning: It is required that the soil and soil layers be deep (60?) and fertile; the soil pH value should be 5.5-7.0; the orchard slope should be less than 25 degrees. In the planning of the garden, necessary roads, drainage, irrigation, water storage and auxiliary building facilities should be provided. When planning concretely, we should concentrate as much as possible on the plan, and establish a park in places with good traffic and water resources.
2. Planting techniques Soil digging and planting holes: The plants were planted at a planting density of 3m from a plant spacing of 2m and 111 plants were planted in acres. Pull line distance, dig and planting hole, depth and width of each hole 80cm, and then press the green manure 50cm deep, backfill soil 30cm high planting. Usually in September-September, after the old shoots are ripe, or before the spring shoot sprouts in the February-March period. When planting, the roots of seedlings will be trimmed moderately and then put into the center of the planting hole to stretch the root system, support the right direction, and gently raise the seedlings while filling the soil to ensure that the roots are in close contact with the soil. Fill the roots with water, make a 1m tree disk around the seedlings, and cover with a mulch. We should do a good job of deepening and deepening the hole and ripening the soil, and prohibit the planting of high pole plants such as corn and wheat in the park, and do a good job of intercropping and intercropping and weeding in orchards.
3. The fertilization method is mainly based on soil fertilization, with the foliar fertilization. The use of ring groove, strip groove, hole application and soil surface fertilizer and other methods. (1) Sapling fertilization. Diligent application of thin application mainly nitrogenous fertilizer, combined with application of phosphorus, potassium fertilizer, spring, summer and autumn shoots fertilization period 5-6 times, (3,5,6,7,9,12 months, each time each plant Ammonium bicarbonate 0.4 kg or urea 0.2 kg.The annual nitrogen application rate of 100-400 g nitrogen per plant of young tree is 1-3 years, and the ratio of nitrogen, phosphorus and potassium is 1.0:(0.4-0.5):1.0.(2) Fertilization The adult tree is applied four times fertilizer, namely budding fertilizer, maintaining fruit fertilizer, strengthening fruit fertilizer, and harvesting fruit fertilizer. Fertilizer amount generally germinates 2-3 kg of fertilizer, one-off manure water, and maintains fruit fertilizer 1-2 kg of phosphorus and potassium fertilizer. 1 kg of chemical fertilizer; strong fruit fertilizer 1-2 kg of fertilizer + 1-2 kg of phosphorus and potassium fertilizer; fruit fertilizer (basal fertilizer) to organic fertilizer, plant applied 50-100 kg of organic fertilizer +1-2 kg of fertilizer.
