Nectarine can be divided into early, middle and late stages according to maturity, and the varieties can be flexibly selected according to the local market supply.

soil management

To create a deep, loose and nutritious soil environment for the roots, we should dig deep or concentrate fertilization before building the garden, and then combine with autumn.

Apply base fertilizer and gradually expand holes. Farming and weeding. Nectarine has a well-developed root system and needs good ventilation conditions. During the growing season, intertillage and weeding are carried out many times to ensure loose surface, which is beneficial to the rapid growth of nectarine. Reasonable intercropping. In order to improve the light and heat of the land, water and gas resources can be properly intercropped in the nursery, but low-stalk and low-crown crops such as green manure, melons, vegetables and beans will not affect the growth and development, spread related diseases and pests, and compete with trees for fertilizer and water.

Fertilize soil or land

Base fertilizer, mainly farmyard manure, is added with calcium superphosphate. From the second year of planting, the base fertilizer per plant 150-200 kg per year; Young trees (2-4 years old) are mainly nitrogen fertilizer, and each tree is fertilized with 1-4 kg per year, with appropriate amount of phosphorus and potassium. In the fruiting period, the ratio of nitrogen, phosphorus and potassium should be increased year by year, generally 2: 3: 2 is appropriate, and other trace elements should be supplemented appropriately.

When the base fertilizer is insufficient or the tree is weak in autumn, topdressing can be 0.2-0.5 kg/plant; If paclobutrazol needs to be controlled, 0.5- 1g/m2 (15% content) can be applied to the soil and then irrigated with water. When the topsoil is not sticky, the whole garden is covered with film. Plastic film mulching is beneficial to keep the ground temperature, especially after irrigation, the ground temperature rises faster.

If it is possible to lay drip irrigation pipe and use drip irrigation instead of flood irrigation, it will not only save water, but also help to control the humidity in the shed.

water

In areas with annual rainfall above 500 mm, irrigation is not needed, but in dry areas in spring, in order to ensure normal development or avoid the harm of late frost. The germination period after thawing requires sufficient irrigation 1 time, and before freezing 1 time. When the fruit is about to ripen, water it every day, river water and reservoir water, not well water. Well water is too cold, and the ground temperature will not come up for a long time, which will affect the growth of fruit trees.

Do plastic surgery

Nectarine tree has strong apical dominance, many branches, fast growth of new buds and easy formation of flower buds. It is important to cultivate high-yield trees in advance. Natural open trees with three main branches and open trees with two main branches are often used, and short and dense layered trees are used, but they should be flexibly mastered according to the cultivation method and density.
