What are the planting and management techniques of yellow peach? To do a good job is easy to produce high yield!

At present, it is the peak season for yellow peach on the market, it is rich in antioxidants, dietary fiber and calcium, iron, zinc and other trace elements. Due to the booming sales, the planting area has been expanding in recent years. So, what is the planting and management technology of yellow peach? To do a good job is easy to produce high yield!

I. selection of land and land preparation

Choose high-lying, sunny, loose and fertile land, plough deeply before sowing, apply sufficient base fertilizer, and open a good drainage ditch.

2. Selection of seedlings

Select the grafted seedlings with more than 3 main and lateral roots, more than 20 cm in length, more than 80 cm in height, more than 1 cm in basal diameter, full growth and good healing of grafting interface. Mountain peach, hairy peach or Qingzhou peach were used as rootstocks.

3. Planting

The cultivated seedlings were planted before November to March of the following year, generally according to the row spacing of 3 meters × 4 meters, planting density of 55 plants per mu, and the planting depth was 3-5 cm above the soil surface at the grafting interface.

IV. Maintenance and management

1. Ploughing and weeding

Deep ploughing is carried out between rows every autumn, and 40cm to 60cm outside the canopy. Young trees can be intercropped with crops such as green manure or beans and ploughed after each irrigation and rainfall. Adult trees are planted with grass between rows, ploughed or covered in rows. Artificial planting of rat thatch, white clover, ryegrass or natural grass. When the interrow grass is 30-40 cm high, cut manually or mechanically, keep the stubble height 8-10 cm, cut 3-4 times a year, and cover the tree plate with the cut grass.

2. Fertilization

Base fertilizer: it was applied in combination with ploughing and turning soil after autumn fruit harvest (September to October). It is calculated according to 150 kg of mature organic fertilizer per 100 kg of fruit, and 1.2 kg of ammonium dihydrogen phosphate and 1.2 kg of potassium sulfate are mixed at the same time. Generally, 3000-4000 kg of high-quality organic fertilizer is applied per mu, mainly in the furrow. The fertilization site is within the projection range of the crown, and the ditch depth is 30cm-45cm. Irrigation after fertilization.

Topdressing: before sprouting and 1 week after anthesis, 0.5 kg urea per 100 kg fruit, 0.3 kg urea per 100 kg fruit in hard kernel stage and 1.0 kg potassium sulfate per 100 kg fruit during fruit expansion period. Irrigate immediately after topdressing and forbid topdressing within 30 days before harvest. Spraying 4% 0.5% zinc sulfate before sprouting; spraying 0.2% borax solution once at full flowering stage; spraying 0.2% urea and 0.2% potassium dihydrogen phosphate before hard core stage. Extra-root topdressing is prohibited within 20 days before harvest. Nutrition diagnosis and fertilization should be carried out in conditional producing areas according to the results of soil and leaf analysis.

3. Irrigation and drainage

Water should be irrigated once with topdressing before sprouting, once at hard core stage, forbidden 15 days before harvest, and frozen water before winter. Dredge the drainage system before the rainy season to ensure smooth drainage in the rainy season. Peaches are afraid of waterlogging, so strictly guard against stagnant water in peach orchards.

5. Pruning

Pruning is divided into summer pruning and winter pruning. The summer pruning time is from April to June, mainly plastic shaping, expanding the crown as soon as possible, cultivating a solid skeleton, mainly sprouting, sprouting, twisting, branch pulling, etc.; winter pruning time from late November to December, mainly summer pruning, the latter as a supplement. Young trees should be cut lightly and heavily in full fruit.

VI. Pest control

There are mainly peach anthracnose, peach brown rot, peach borer, pear heart borer, peach aphid, leaf moth and other diseases and insect pests. We should actively implement the policy of "prevention first and scientific prevention and control", promote biological control on the basis of agricultural and physical control, and scientifically use chemical control techniques in accordance with the law of the occurrence of diseases and insect pests.

Finally, we need to remind you that when planting yellow peaches, we should not only achieve the above management techniques, but also plant in suitable areas to ensure its yield and quality.
