Where are pistachios suitable for planting? why does no one grow pistachios?

Speaking of pistachio, presumably many people are no stranger, it is a more common nut in life. In recent years, the market price of pistachios is high, so it attracts a lot of people's attention, but when planting, location is also very important. Let's take a look at it together.

Where are pistachios suitable for planting?

1. Soil: pistachio trees have strong adaptability to soil and can grow on almost all types of soil, especially deep, thick, light or dry calcareous sandy loam and yellow loam, in clay loam, sandy gravel soil, shallow chestnut soil, light loam, slightly salinized soil, etc., pH7.7-8.0, it can also grow and bear fruit in gravelly, thin mountain and semi-desert land, and it needs trace elements such as potassium and iron, and the fruit is not tolerant to saline-alkali. Cannot grow in places that are too wet and stagnant.

2. Moisture: pistachio trees are suitable for planting in the range of 200-400 mm annual precipitation, which grows well and bears full fruit, while in areas with annual precipitation below 80 mm, they can also stubbornly grow, blossom and bear fruit, but the lack of water in the sensitive period of summer water demand will lead to no harvest of fruit grains.

3. Temperature: pistachio has strong adaptability to temperature. In Shufu County, Xinjiang, it can withstand 42 ℃ high temperature and-26 ℃ low temperature limit. In Sicily, the summer temperature is 23 ℃, the average temperature is 7.8 ℃, and the low temperature-3 ℃ has no harm to the tree. In the United States, it can tolerate a low temperature of-14.5 ℃, while in Iran, from-9.5 ℃ to 42 ℃, and in some parts of the former Soviet Union, Iran is the most suitable place for pistachio growth. The average January temperature variance in 7 years is-15 ℃, and the average temperature is 7.2 ℃.

Why doesn't anyone grow pistachios?

Pistachio is not uncultivated, but the geographical conditions of many places are not conducive to the growth of pistachio, after planting can not survive, so planting less. Pistachios are most suitable for Kashgar, Aksu and Hotan in Xinjiang, which can be planted around the desert in theory. In practice, Hami in Xinjiang, Hexi Corridor in Gansu and Gangu County in China have been planted successfully, but the experiments in other places are not ideal.

How to grow pistachios

1. Soil: pistachio trees have strong adaptability to soil and can grow on almost all types of soil, especially deep, thick, light, or dry calcareous sandy loam and yellow loam. in clay loam, gravel soil, shallow chestnut soil, light loam, light salinized soil and so on. Soil ph7.7-8.0. It can also grow and bear fruit on barren and thin mountain and semi-desert land. Growth requires trace elements such as potassium and iron. Pistachios are not tolerant to salinity and cannot grow in places where they are too wet and stagnant.

2. Watering: pistachio trees generally grow well and bear full fruit in the range of 200-400 mm of annual precipitation, while in areas with annual precipitation below 80 mm, they can also grow tenaciously, blossom and bear fruit, but the lack of water in the sensitive period of summer water demand will lead to no harvest of fruit grains.

3. Temperature: pistachios have a strong ability to adapt to temperature, and can adapt to temperatures from 73.4 degrees f to sub-zero temperatures at the same time. Of course, pistachio trees need enough cold winter to break bud dormancy and long, hot and dry summers to ripen the fruit. Pistachio trees grow better when the highest range is 43.8 degrees Celsius to minus 32.8 degrees Celsius.

4. Propagation techniques: pistachio trees can be propagated by many methods, such as sowing, grafting, ramet, striping, root tiller and so on. The young trees enter the fruiting age relatively late, if the seedlings are planted in 7-8 years, the root tiller seedlings of the ramets are about 5 years, and the grafted trees are 3-4 years, the general plant produces about 15 kg of nuts.

Diseases and control of pistachio

1. Gummy disease. Scrape off the flowing glue in time, remove the scraped glue, burn it centrally, and apply 0.2% nail purple lotion to the spot after scraping. Spray stone sulfur mixture before the tree sprouts.

2. Leaf spot. Clean the fallen leaves of pistachio, cut off the diseased leaves and burn them centrally. During the onset period, spray the whole plant with Bordeaux liquid in time.

Pistachios are suitable for planting in places with plenty of rain, and the requirements for the soil are not very high. It is not that there is no seed of pistachio in our country, in fact, it is only because of its living habits, so there are not many people who plant it. When planting, the site selection must be done well, and the later management is also very important.
