Climatic conditions required for pistachio cultivation Hot pistachio shell and long summers and cold and long winters for cultivation Pistachios are recommended. Temperature 45 degrees Celsius in summer and minus 20 degrees Celsius Tolerates well in winter. Of course, the degree of resistance in terms of growth stage Plant, plant age, type of cultivar, nutritional status and irrigation are different. Pistachios to cold Late spring is sensitive. Early spring heat also causes the flowers to die and Fruits at the beginning of the season and excessive heat during the closing of the brain and fruit growth, cause miscarriage Fetus and increase the percentage of fruit emptiness. There are gentle winds with a speed of about 10 Kilometers per hour is required at the time of flowering, but hot, dry winds are stormy And is problematic with dust. Familiarity with operations It was raining with pistachios, rain at the time of flowering, fruit growth, ripening and Harvest the crop. These problems are caused by the increase in humidity Relative garden environment, stigma washing and disturbance in proper distribution of pollen grains Be. In general, the suitable place for growing pistachios should be considered where It should not rain about a month before the harvest season and during the harvest time In order not to create a favorable environment for the growth of fungal agents in it. Relative humidity of the environment from Pistachio orchards should be established in areas where the relative humidity is above 70% Avoided. To have the maximum yield, the relative humidity in summer is a must Be less than 35%. Increased relative humidity at the time of flowering and pollination Reduces pollination efficiency and thus reduces fruit formation over time The ripening of the fruit also causes the spread of fungal diseases, including increased contamination of the crop Turns to aflatoxin. Generally there are hot, dry and long summers Cold and mild winters, including environmental factors suitable for planting pistachios Early spring heat also causes the loss of flowers and fruits The beginning of the season and the excessive heat during the closing of the kernel and the growth of the fruit, cause abortion Fetus and increase the percentage of fruit emptiness. There are gentle winds with a speed of approx 10 km / h is required at the time of flowering, but the wind is hot and dry Stormy and dusty are problematic. Familiarity with operations With the pistachio tree, it rains at the time of flowering, fruit growth, ripening And makes it difficult to harvest the product. These problems are caused by an increase in humidity Relative garden environment, stigma washing and disturbance in proper distribution of pollen grains Becomes. In general, a suitable place for growing pistachios should be considered somewhere Which is about one month before the harvest season and during the rainy season Not to create a favorable environment for the growth of fungal agents in it. Relative humidity Environment of pistachio orchards in areas where the relative humidity is above 70%, Should be avoided. To have the maximum yield, the relative humidity in summer is a must Be less than 35%. Increased relative humidity at the time of flowering and pollination Reduces pollination yield and thus reduces fruit formation over time The ripening of the fruit also causes the spread of fungal diseases, including increased contamination of the crop Turns to aflatoxin. Generally there are hot, dry and long summers And cold and temperate winters, including suitable environmental factors for pistachio cultivation is.
