1. Soil conditions: Choose a place with deep soil layer, good air permeability, high organic matter content and watering conditions to build the garden. Where the soil is thick and the fertility is thin, it is not suitable for planting.

2. Row spacing of density plants: 2.5 # 215; 4 meters or 2 # 215; 4 meters is suitable. When preparing soil, the planting ditch with a width of 100 cm and a depth of 60-80 cm should be excavated along the direction, or the whole garden should be turned about 60 cm deep. ?

3. Planting pollination trees: The pistil of Golden Pear is developed, the stamens are degenerated and the pollen is less. More than two varieties should be arranged as pollination trees with a ratio of 5 to 8: 1. Pollination varieties should be Gaoxing, Xinxing, Daguo Crystal, Aidang, Twentieth Century, Emerald and so on. The economic benefit is higher and the flowering period is the same.

4. Planting: select strong seedlings with complete root system and height of more than 80 cm to plant, and set holes by pulling wires according to the requirements of plant spacing. The planting hole is about 40 cm deep, and each hole is applied with 50 kg of soil fertilizer and 0.5 kg of Bika compound fertilizer. Before planting, the roots of Barneda Bika were dipped in Can Cong to promote rooting. Cover the soil to the roots of the seedlings. After planting, water, cover with plastic film, and set the drying height to 70 cm. If the height of the seedlings is less than 70 cm, the terminal buds should be kept and not dried. In order to prevent seedlings from losing water and pests from destroying germination, a closed plastic film bag with a width of 7 ~ 8 cm and a length of 30 ~ 35 cm can be set. When the new shoots grow to 3 cm in the bag, cut off a corner of the bag mouth for ventilation. After 5 ~ 6 days, the top of the bag is cut open, and the 1/3 of the bag is cut open from top to bottom, and it is pulled under the tether in an inverted horn shape to prevent pests from hurting new buds on the tree. ?

Second, the management points

1. Sufficient base fertilizer: every autumn or early spring, 2,500-5,000 kg (generally 1 kg fruit 1 kg fertilizer), 5 kg of Bika bacterial fertilizer and about 5 kg of Banida Bika compound fertilizer are applied per mu. Apply fertilizer by radial fertilization method, and water after fertilization.

2. Rational topdressing: It should be carried out before flowering, in the flourishing period of spring shoots and in the fruit expansion period. It is mainly composed of compound fertilizer and diammonium phosphate. After the flowers wither and before bagging, spray them together, and apply amino acid compound fertilizer or urea with 1200 times of Picard silicon-soluble potassium dihydrogen phosphate solution for 2-3 times.

3. Flower thinning and fruit thinning: flower thinning should be carried out in the early stage of flower bud expansion or combined with pruning, and fruit thinning should be completed within half a month after fruit setting. Only one fruit is left in each inflorescence, the spacing between the fruits is 25 to 30 cm, and the yield per mu is controlled within 2500 kg. All axillary buds and fruits should be thinned out.

4. Full bag: Golden pears must be bagged, otherwise the fruit surface will be rough. Double bags immediately after fruit thinning, the sooner the better. Before harvesting 10 days, the bottom of the bag is torn and the fruit can turn golden yellow. In Japan, golden pears are generally bagged twice, that is, a single-layer small bag is put in the young fruit period (3 weeks after the full flowering period), and the small bag is removed and replaced with a large bag after 6-7 weeks after the full flowering period (the middle period of fruit growth and development). Disinfect the insecticide and put it in a big bag.

5. Trimming: V-shape, happy shape, spindle shape and improved spindle shape can be used. This variety is easy to blossom, and the tree is easy to weaken after continuous fruit bearing. Attention should be paid to cultivating strong fruiting branches and pruning them in appropriate parts to improve and maintain yield.

6. Pest control: Before germination, spray 3 degrees of stone sulfur mixture +200 times of sodium pentachlorophenol. Do not spray any chemicals containing copper ions or irritating emulsifiable concentrate before bagging. You can choose powder or water solution. Polyoxin, diniconazole, thiophanate-methyl and Nong Kang 120 can be used to control diseases, and copper preparations such as Bordeaux solution can be sprayed to protect leaves after bagging. Insect pests can be controlled by pesticides such as diflubenzuron No.3, chlorfenapyr, chlorfenapyr, Aifuding, Wanling, chlorfenapyr and cartap.
