Recognition of climatic conditions of pistachios

Recognition of climatic conditions of pistachios Spring rains, pistachio shell frosts, and hot, drying winds prevent inoculation and high humidity during the growing season can exacerbate the onset and damage of fungal diseases. Strong winds also have an adverse effect on the cultivation of young seedlings. To help awaken and grow dormant buds and produce normal inflorescences and accelerate plant growth and fruiting in California at least a thousand hours of winter cold below 7ºc Is needed. And if the total temperature is less than 670 hours (as happened in 1977-78), the flowering and leafing of the tree is delayed and the leaves become irregular and unkempt, and crop production is reduced. In addition, no chemical substances or solutions provide or compensate for such deficiencies. Pistachio tree can be easily planted in most soils with different texture and material so that in calcareous and saline soils its strength and tolerance has been better than other fruit trees, but in shallow and hard lands and hard and rocky results It does not show well. The best soil for pistachios is sandy and clay soils with good drainage and ventilation. The deeper and more uniform, the better the growth and the higher the production.
