How to grow pistachios

Pistachios are very popular. The economic value and medicinal value of pistachios are relatively high. Many growers have begun to plant pistachios. So how to grow pistachios?

1. Planting time of pistachio trees

Pistachio trees can be sowed in spring or autumn. Spring sowing requires sand storage of seeds, which is carried out in the first and middle of March and when the temperature reaches 10-15 ℃, while autumn sowing takes place from mid-October to late November, and seeds do not need to be treated.

II. Planting methods of pistachio trees

1. Growth habits: happy fruit like light, growing in the sunny slope mountain area of 600m-1200 m above sea level, deep calcareous soil, well-drained loose sand loam grows well, plants are not resistant to moisture and afraid of stagnant water.

two。 Orchard location: although pistachio is resistant to barren, drought, cold and strong adaptability, it is planted in loam and sandy loam with deep soil layer and good ventilation. As pistachios are extremely vulnerable to late frost, we should pay attention to choose the middle of the hillside, open flatlands, valleys and south hillsides to avoid the wind, and do not build the garden on the windward side of the main wind.

3. Seedling planting: the suitable row spacing of pistachio plants is 3 m × 4 m or 4 m × 5 m, and 33-55 plants are planted per mu. The dense planting garden can plant 83-111 plants per mu, and both finished seedlings and bud seedlings can be used for planting seedlings. Before planting, dig the planting pit with a depth and diameter of 60 cm. When planting, the root is the same as the ground, while planting, step on the soil, and then pour water.

4. Fertilizer and water management: scientific fertilization young trees apply base fertilizer once a year, about 20 kg per plant. The fruiting tree was applied once in 2-3 years. Fertilization is generally divided into three times in a year, the second is in early spring or autumn and winter, mainly available nitrogen fertilizer. The second time in the fruit expansion period, mainly nitrogen and potassium fertilizer. The third time after fruit harvest, mainly compost, barnyard manure and other organic manure, usually combined with deep ploughing in autumn. Timely irrigation before winter irrigation, the effect is better.

5. Shaping and pruning: pistachios are light-loving and dry, mainly free spindle shape in high-density cultivation orchards and natural happy shape in low-density cultivation orchards. The species is free spindle-shaped, characterized by a central trunk, in different parts of the central trunk, scattered 10-15 main branches, the main branches and trunk maintain 80-90 degrees, directly bear small and medium-sized fruiting branches on the main branches; the second is a natural happy shape, mainly characterized by good ventilation and light transmission, trunk height of about 40-50 cm, 3-4 main branches selected on the trunk, base angle 45-75 degrees, 2-4 lateral branches, equipped with branch groups on the side branches. Pistachio has a strong ability to branch, and the principle of pruning is more thinning and less cutting. Pistachios are mainly short fruit branches, young trees and early fruit trees grow vigorously, and there are more middle and long fruit branches. generally, when the new shoots grow to about 50-60 cm, pick the heart in time, promote secondary shoots, increase fruiting branches, retain upper dorsal branches and erect branches, and twist them in time, which can be formed in the second winter after planting.

6. Flower and fruit management: strengthen the comprehensive management of orchards to enhance tree potential, promote flower bud differentiation, apply more organic fertilizer; rational allocation of pollination trees. Pistachio self-flowering does not bear fruit, generally every two rows of main varieties, the configuration of one row of pollination varieties, to create conditions for normal pollination of pistachios, which is helpful to improve the fruit setting rate.

Pistachios are relatively easy to manage, and the economic benefits of planting are also very good. If you want to plant pistachios, you can refer to the above content to plant.
