In fields with fresh water and soil, the germinatedIranian Pistachio seeds intended for sowing are sown in the place of the main land after the soil has been plowed (reaching the field capacity). If the field soil is heavy, the inside of each pit is covered with sand in order to seal the seeds. This helps the plant to grow, because not only does it provide enough oxygen to the roots of the seedlings, but it also activates the beneficial aerobic organisms in the soil. The depth of seed sowing depends on the size of the seed (planting depth is about 2 to 5 times the diameter of the seed) In Iran, pistachio seeds are sown in two ways.
The first method of sowing pistachio seeds:

Sowing seeds in plastic pots in the greenhouse is at the end of September or the first of March. The seedlings are transferred to the main land after one year of growth in the greenhouse.
In the second method of planting pistachio seeds:

Seeds are sown directly in the ground in mid to late April. Some gardeners think that direct sowing of seeds in the mainland, although delayed in growth compared to potted seeds, will result in stronger plants than potted seedlings after a few years.
Planting pistachio seeds in the treasury:

The ground of the pistachio treasury, like the treasury of other trees, must be prepared. The distance between sowing seeds on the planting bed is between 5 to 10 cm and between lines 35 to 40 cm. After sowing the seeds, they are covered with aerated sand along with livestock manure and irrigated. The amount of pistachio seeds used in pistachios is 250 to 300 kg per hectare and about 250,000 pistachio seedlings can be produced per hectare.

Produced seedlings are ready to be transferred to agricultural land in autumn and winter (annual seedlings). The higher the age of pistachio seedlings in the treasury, due to the expansion of the root system and the complexity of the roots of pistachio seedlings and the inaccuracy in moving the seedlings to agricultural land and cutting the roots, it is done at once.

Corridors are built in the treasury at distances of 1.5 to 2 meters, which helps workers move to remove weeds and carry out irrigation and grafting of seedlings. If the floor of the treasury is carpeted with cement or mosaic, it prevents the roots from growing downwards. Therefore, the seedlings will be easier to move and their losses will be less.

Knowing the general information of the pistachio plant

An overview of the knowledge of the pistachio plant and its information

What we know is that the highest pistachio cultivation area is in Kerman (Rafsanjan city). 2% cultivated (base) in America is Kerman variety. The highest yield among the cultivars is related to the Pistachio Kale Gochi variety. The popularity of the Kale Gochi variety and the increase in cultivated area are related to the high production of this variety.Iranian Pistachio

Selection of the base is the main goal during the construction of pistachio orchards. Cultivated base and transplanted variety of Khorasan Gardens is related to Kale Ghochi variety. About 90 pistachios are known in Iran, of which 30 of the 90 are found in Khorasan.

Kale Gochi variety is sensitive to spring cold due to its early flowering. Kale Gochi cultivar is sensitive to the examination of nutrients and their reduction. In post varieties, Ahmed Aghaei variety has the highest yield. The post tree should be watered every 12-10 days for 2 to 12 years. Fruit trees should be watered according to the schedule depending on the time and need. It is better to water fruit trees once a month.

It is better to use organic fertilizers (cow, chicken, etc.) in a fully decomposed and composted form. The best depth of chalkwood in low trees is 30 to 40 cm. Concerns about the opening of the buds, the state of sweeping and small leaves are related to the issue of zinc.

Nutritional symptoms in pistachio plant

The obvious symptoms of calcium tabular leaves are in the length of the leaves and the thinning of the clusters. Sunburn and the reduction of smiling fruit are related to potassium. The potash plant is resistant to several water-dry stresses and environmental stresses. The highest number in low trees is related to nitrogen. The yellowing of old and purple leaves at the edges of the leaves and the falling of leaves and fruits are among the symptoms.

Khorasan soils are calcareous texture with high pH. The private pH of Khorasan gardens was between 8 and 9 due to calcareous soil and drought, which is a danger. The reddening of one-year branches and the falling of leaves and their drying are symptoms of salinity. Too much of one factor reduces the absorption of other elements in the soil.

The excess of magnesium element in the soil causes the lack of absorption of potassium and calcium. One of the destructive effects of salinity is the thirst of the plant and the movement of nutrients in the soil. Soluble salts in the soil include chlorine, sodium, bicarbonates, sulfate and magnesium.ش
