Planting conditions of pistachio
1, soil
Happiness cannot be exacted from the soil. It is suggested that happiness trees should be planted in deep or dry calcareous sandy loam, and should not be planted in places that are too wet or have more water.
Step 2: Moisture
Generally, the annual precipitation in the suitable planting area of happy fruit trees is 200-400 mm, and it can grow, blossom and bear fruit tenaciously in areas with annual precipitation below 80 mm, but the lack of water in the sensitive period of water demand in summer will lead to fruit failure.
3. Temperature
Pistachio nuts are drought-tolerant, light-loving, and have strong adaptability to temperature, and can develop normally at both high and low temperatures. It should be noted that happy fruit trees require a large temperature difference between day and night in the fruiting period, and the regional temperature ranges from 43.8 degrees Celsius to MINUS 32.8 degrees Celsius, and the fruit grows well.
