The fruit tree has been growing for several years.

Pistachio, also known as pistachio, is a small deciduous tree of Coptis in the lacquer family, native to Syria, Iraq, Iran, southwest of the former Soviet Union and southern Europe, and then introduced into remote areas of China. The main root can reach 7 meters deep into the soil, the horizontal branch root can reach 10-15 meters, and the tree age can reach 300 years. Let's take a look at the fruit of pistachio trees in a few years.

Pistachio trees bear fruit for several years

Pistachio tree is a kind of plant with long age and slow growth. it takes at least six years for seedlings to bear fruit from the first year of seed planting, and the fruiting rate increases year by year. 14 to 70 years after planting is the full fruit period. The grafted seedlings began to bear fruit in the third year and entered the full fruiting stage in the sixth year. A sturdy and healthy pistachio tree can harvest 100-200 kg of fresh fruit per year, and the average pistachio tree can produce 70-130 kg of fresh fruit per tree per year, with a dry fruit rate of 30%.

The growth habit of pistachio

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, mildly salinized soil, etc., soil PH7.7-8.0. it can also grow and bear fruit in gravelly, thin mountain and semi-desert land, which requires trace elements such as potassium and iron, and is not tolerant to salt and alkali. Cannot grow in places that 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, and they can also grow tenaciously and blossom and bear fruit in areas with annual precipitation below 80 mm. However, 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 Celsius to below zero at the same time. Of course, pistachio trees need enough cold winter to break bud dormancy and long, hot and dry summer to make the fruit mature. The fruit is better in the range of up to 43.8 degrees Celsius to minus 32.8 degrees Celsius.

An excellent variety of pistachio

1. Long fruit pistachio: the fruit shape of long fruit pistachio is long oval, there is a red halo around the fruit, the top of the fruit is pointed, the vertical diameter length is 2.5 cm and the transverse diameter length is 1.1 cm, the fruit setting rate of the fruit tree is very high, and it has strong high yield. it is a large fruit type variety with the most promising growth.

2. Early-maturing pistachio: the precocious pistachio tree is weak, the branches of the fruit tree are curved and drooping, the fruit shows lenticels, the lenticels are white, the shape of the lenticels is round and very prominent, the fruit setting rate is medium, and the fruit is oval in shape, with a vertical diameter of 1.9 cm and a horizontal diameter of 1.0 cm, showing a red color on the top and sunny side of the fruit. There are obvious stripes on the pericarp of the fruit.

3. Short-fruit pistachio: the short-fruit pistachio tree has medium potential, smooth leaves, sparse hairs covering it, low fruit setting rate, oval fruit, yellow-white fruit color, 2.1 cm in vertical diameter and 1.3 cm in transverse diameter.

4. Noterol: Noterol fruit tree is a central Asian group, which produces a large pistachio fruit, the flavor of the fruit is not very good, the seeds are green and the cracking rate is high.

5. Dahan: the growth potential of Dahan fruit tree is very exuberant and belongs to the variety of late flowering. The fruit has the characteristics of high quality, high yield and large fruit, and the quality is the best among pistachios.

6. Coleman: the Coleman fruit tree is a female plant, which has the characteristics of large fruit and high yield. the serious phenomenon of hanging fruit every other year is one of the phenomena of the fruit tree, and the remaining phenomenon is that the empty shell and the fruit shell do not crack, and the fruit tree grows vigorously. The advantages of late flowering, high quality, large fruit and high yield are as follows: the single kernel weight of the fruit is 1.3 grams and the green quality of the kernel is good.

7. Sarell: the tree potential of Sarile fruit tree is moderate, which has the characteristics of high yield and easy fruiting, the fruit setting rate is very high, and the white and high quality of large nuts are all the characteristics of this kind of fruit.
