A Complete Analysis of the Latest Management Techniques for Greenhouse Nectarines

Nectarine is an excellent variety of peach. To improve yield and quality, many fruit growers mostly adopt greenhouse cultivation, and greenhouse nectarine cultivation differs slightly from open-field cultivation. So how should greenhouse nectarines be managed? Let's take a look with the editor.

1. Site selection and greenhouse construction

A nectarine greenhouse should preferably be located in a place that is sheltered from the wind and faces the sun, with dry terrain, convenient drainage and irrigation, and fertile, loose soil. It can be built within a peach orchard, or the greenhouse can be built first and then the trees transplanted, depending on the actual situation. For greenhouse construction, choose a bamboo and wood structure, with the back wall made of hollow cement bricks. The height, length and width of the greenhouse depend on the actual situation. Use polyethylene drip-free film for the greenhouse film, and make ventilation holes in the back wall, generally leaving one about 30 cm in diameter every 10 m. Skylights should likewise be made in the center of the greenhouse roof.

2. Transplanting seedlings

If the greenhouse is built within a peach orchard, there is no need to transplant; only relatively intensive fertilizer and water management is required. For a newly built greenhouse, before transplanting, the soil should be deeply plowed, and each greenhouse should be given 4000-5000 kg of organic fertilizer, 20 kg of compound fertilizer, and 10 kg of potassium sulfate as base fertilizer. The seedlings selected for planting should have a well-developed root system, robust growth, and plump buds. When planting, control the spacing between plants and rows at 1.5 m × 4 m, and keep the ratio of the main cultivar to pollinator cultivars at about 10:1. During planting, keep the root system spread out. After planting, water thoroughly once, and cover with film to keep warm and retain moisture.

3. Training and pruning

For greenhouse nectarine training and pruning, a sloped population structure that is higher in the north and lower in the south is generally adopted. If the tree form is spindle-shaped, control the tree height at about 1.5 m; if the tree form is open-center, control the tree height at 1 m. Pruning before covering the greenhouse is mainly thinning branches, leaving long branches and letting them extend, thinning out diseased and pest-damaged branches, drooping branches, water sprouts, and non-flowering branches, while strengthening vegetative branches and maintaining permeability between plants.

4. Fertilizer and water management

One month before covering the greenhouse, each greenhouse should be given 3000 kg of organic fertilizer, 25 kg of diammonium phosphate, and 10 kg of urea, and watered thoroughly once at the same time; then shallow hoe to break the soil and cover with plastic film. During the young fruit stage, spray a low-concentration urea solution once. During the pit-hardening stage, in addition to the urea solution, spray a potassium dihydrogen phosphate solution once more. From covering the greenhouse until petal fall, watering is not advisable, and the humidity inside the greenhouse should be controlled below 60%. During the fruit stage, watering is generally done twice, once at the pit-hardening stage and once at the fruit enlargement stage, but pay attention to the amount of watering; it should not be too much, so as to avoid excessive growth of new shoots, which can cause physiological fruit drop and affect yield.
