What planting techniques do peach trees have?

What planting techniques do peach trees have? Peach tree planting has the following six technical points: 1. Peach is used as rootstock in peach grafting propagation, and bud grafting or cutting is suitable for grafting. two。 Peach trees should be planted in winter and spring, as well as in autumn. The density is 4 × 3 m in flat land and 3.5 × 2.5 m in mountainous area. It will be gradually thinned out when the adult is too dense. The hole is 80 × 100 cm wide and 50 cm deep. 3. Peach tree pruning is very important, the time is divided into winter pruning: there are natural happy type, two main branches open type and oblique palm leaf fan shape, while summer pruning is mainly to pick the heart and control the overgrowth. 4. Some peach trees with little pollen have poor self-pollination and should be pollinated with other varieties of peach trees. Some varieties mixed with more than two can be cross-pollinated to improve the seed setting rate. 5. Fertilization: give priority to soil fertilizer, properly apply chemical fertilizer containing nitrogen, phosphorus, potassium and a small amount of trace elements such as calcium, magnesium, sulfur and iron, and apply sufficient base fertilizer. Topdressing should be applied once before flowering, during fruit expansion and after fruit harvest. 6. Prevention and control of diseases and insect pests: (1) Peach brown rot: the main harm to the fruit, the initial appearance of brown round disease spots on the fruit surface, and then spread to the whole fruit, the flesh becomes brown and soft rot. Control methods: to remove the source of overwintering bacteria, control weevil, Toona sinensis and other communicators, spray Baume 4-5 degree stone sulfur mixture during germination, can also use Dysen zinc, topzine and other antibiotics. (2) Peach anthracnose: it mainly harms the fruit, the disease is more serious in damp and rainy, and it becomes stiff peach after the young fruit is damaged. After the fruit is enlarged, the watery spot expands into a round, reddish brown, sunken spot. Control methods: remove the overwintering source, spray 4-5-degree stone sulfur mixture and thiophanate in early spring, carbendazim and other antimicrobial agents. (3) Peach leaf shrinking disease: the overwintering pathogen invaded after sprouting and spreading leaves, shrinking and twisting into deformed leaves, and the diseased leaves were fat and gradually turned reddish brown. The control methods were basically the same as those of the above two diseases. (4) Peach bacterial perforation: the overwintering pathogen was transmitted by wind, rain and insects from April to May, the leaves were watery spots at first, then the disease spots expanded to reddish brown, and the disease spots dried up and caused perforation and fallen leaves. It will harm the fruit in the future. The methods of prevention and treatment are basically the same as those of the above three diseases. (5) bacterial root cancer: apples, peaches, plums, plums, cherries, grapes and other fruits are susceptible. The source of the disease survives in the soil, spreads with running water, soil and insects, and invades from the wound. After the seedlings were injured, the development was blocked, the growth was slow, and the life span was shortened. Prevention and treatment methods: select disease-free nursery land, prevent heavy mulch, remove root nodules, root stone-sulfur mixture and Bordeaux solution to protect the wound before planting, soak the roots of seedlings with fungicides for 10 minutes. (6) Peach tree rot disease, also known as gum disease: overwintering bacteria spread coal media through wind and insects, which was prevalent from April to May, from rice grain to tree stem to tree stem death. Antimicrobials can be used to prevent and cure it. Alkali, purple potion, 402, 843 rehabilitation agents, potassium permanganate and so on. More peach tree planting techniques
