Detailed Explanation of Key Points on Greenhouse Nectarine Cultivation Techniques

Nectarine is a variety of the common peach, with a beautiful appearance and a sweet-and-sour taste. It has relatively high nutritional value and cultivation value. Below let us take a look at greenhouse nectarine cultivation techniques.

I. Building the shed and preparing the soil

Nectarine is suitable for growing in a loose, deep and nutrient-rich environment, so when choosing a site, try to choose loam rich in organic matter for building the shed. The greenhouse for growing nectarine usually uses a plastic-film solar greenhouse. After the shed is built, deeply plow and level the soil, then dig a planting trench 60-80 cm deep and 80-100 cm wide, with a row spacing of 1 m, and apply 5000 kg of organic fertilizer and 100 kg of calcium fertilizer per mu.

II. Transplanting and planting

After the nectarine saplings have been cultivated, plant them at a spacing of 3 m between plants and 5 m between rows.

III. Time for covering the shed

Covering the shed to increase temperature depends on whether the natural dormancy of the cultivated variety has been completed. Generally, varieties with low chilling requirements are covered early, while those with high chilling requirements are covered late. In Hetian, the covering time generally runs from late December to late January of the following year. The earlier the cover, the earlier the ripening. Another basis for determining the covering time is the expected time for the fruit to go on the market. If the expected market time is later, the covering is later. Covering in stages can avoid a concentrated market period.

IV. Management inside the shed

1. Temperature and humidity control

After covering the shed, the temperature inside gradually rises to 15-20°C, the soil temperature rises to 14-18°C, and the relative air humidity reaches 40-60%.

During the flowering period, the temperature inside the shed should preferably be around 20°C, not exceeding 25°C at most, and the nighttime temperature must not be lower than 5°C. To ensure the temperature does not drop below 5°C, use a stove to raise the temperature or light an alcohol lamp for heating when a cold wave occurs. The relative humidity should not exceed 60%.

Fruit enlargement period: control the daytime temperature at around 25°C, not exceeding 28°C, and not lower than 10°C at night.

2. Fertilizer and water management

In order to reduce water evaporation from the ground, lower humidity and increase soil temperature, the ground should be covered with plastic film. Irrigate before covering the shed, and after covering the shed irrigate as little as possible or not at all.

Topdressing should be carried out before budding, during flowering and during the fruit enlargement period. Compound fertilizer is preferable. Pay special attention to the spraying of foliar fertilizer. Starting 10 days after flowering, spray urea or monopotassium phosphate once every 10-15 days, for 2-3 consecutive times.

3. Pest and disease control

Pests and diseases in greenhouse nectarine are relatively mild. The main issue is that after the fruit is harvested and the shed is uncovered, midsummer arrives, so various pests and diseases should be monitored promptly and controlled in good time. Before covering the shed, spray 3-5 degrees Baume lime sulfur mixture, and clean up fallen branches and leaves. When two-spotted spider mites cause damage, spray 2000 times dilution of mite-killing agent, and use aphid-killing agent to control aphids.

Greenhouse nectarine cultivation is basically the same as that of ordinary peaches. Controlling the temperature and humidity inside the shed well is the key link for increasing the fruit-setting rate and achieving early production, high yield and good quality.
