Zhang Pu yellow peach cultivation

Site selection

Choose an area with convenient transportation, convenient irrigation and drainage, far away from the factories with heavy metal pollution and harmful gas sources, with sufficient water sources, no continuous cropping and easy division of communities. The environmental requirements of the place of origin meet the requirements of NY/T 391.

Variety selection

Yellow-fleshed peach variety "Jinxiu" was taken as the main variety, and one-year-old grafted seedlings with Maotao as the rootstock were selected for planting.

planting management

single row ridging cultivation method is adopted to plant seedlings, with the ridge width of 1.2 m and the height of 3 cm, the distance between the center lines of two adjacent ridges is not less than 5 m, and the seedlings are planted on the center line of the ridge direction. The tree is mainly composed of three natural happy branches and two Y-shaped branches. The row spacing of naturally happy plants is (3 ~ 4) m× (5 ~ 6) m, and the row spacing of two main branches of Y-shaped plants is (2 ~ 2.5) m× (5 ~ 6) m, so it is suitable for planting in the north-south direction. Before planting seedlings, dig planting ditches or holes, and apply 3 kg~4 kg organic fertilizer per mu. Immediately after the seedlings are planted, dry them and leave at least 6 full buds. After planting, erect bamboo poles or wooden sticks at 5 cm around the seedlings to support the seedlings.

Grafting management

Peach should be selected as the rootstock. Grafting with xylem by bud grafting is carried out in summer. The leaf buds on the scion should be full and the buds should be full.

field management

① soil management: after defoliation, before soil freezing, combine with applying base fertilizer in autumn, and dig deep and expand holes. With the planting point as the center, turn outward deeply every year or every other year, with a depth of 4 cm~6 cm, so as to avoid hurting the backbone roots. Arrange the tree tray, apply organic fertilizer, backfill the soil and seal the frozen water. Arrange the tree tray, apply organic fertilizer, backfill the soil and seal the frozen water.

② Fertilization: apply base fertilizer deeply after defoliation in autumn and topdressing in time during the growing season. Apply base fertilizer from September to late October after fruit harvesting, apply commercial organic fertilizer of 1-15 kg/mu to trees in full fruit stage, mix soil and fertilizer evenly, and irrigate. Nitrogen fertilizer was applied again in the early stage of tree growth and development, and phosphorus and potassium fertilizer were applied in the later stage. Apply 1 kg/ mu of urea in holes or furrows before germination in early March; Apply 15 kg compound fertilizer per mu in early June.

③ irrigation: intertillage and weed 3 times a year. Before germination in spring, combine topdressing and irrigate once. Control water at flowering stage and maintain moderate drought. During the period of rapid fruit expansion, ensure sufficient water supply, and control irrigation about 1 d before fruit ripening. When applying base fertilizer in autumn, water should be poured once, and frozen water should be poured before soil freezing.

④ Pruning: Young trees grow vigorously, so summer pruning should be emphasized. Older plants are restrained before and promoted after, retracted and updated, and new fruiting branches are cultivated and constantly updated.

⑤ flower and fruit management: flower thinning is carried out from the big bud stage to the early flowering stage, and the principle of flower thinning is to remove the flowers at the top, back and lower part of the branch, and keep the flowers at both sides of the middle part of the branch. Fruit thinning can be divided into two stages: fruit thinning and fruit setting, which are carried out in late April when the large and small fruits are clearly defined. The yellow fruits, small fruits, diseased fruits, deformed fruits, combined fruits, leafless fruits are thinned out, and the fruit is set in early May, with 3-4 fruits left for long fruit branches, 2-3 fruits left for middle fruit branches and 1 fruit left for short fruit branches, and the yield per mu is controlled at 13. Spraying insecticide and bactericide once in the whole garden after fruit setting, and bagging the fruit, with yellow single-layer bag or yellow single-layer bag outside and black inside as appropriate.

pest control

actively implement the plant protection policy of "prevention first, comprehensive prevention". Based on agricultural and physical control, we advocate biological control, scientifically use chemical control technology according to the occurrence law of pests and diseases, and effectively control pests and diseases.

③ biological control: protecting natural enemies such as ladybugs, lacewings and predatory mites; Use pheromones, beneficial microorganisms or sex attractants to lure and trap, such as sex pheromones of pear fruit borer and Bacillus thuringiensis.

④ chemical control: common pests and diseases include peach aphid, brown rot, brown spot perforation, peach borer, pear fruit borer, etc. In production, highly toxic and residual pesticides are prohibited. In the same production cycle, drugs should be used alternately and the same drug should not be used for many times.
