Potassium as one of the most consumed pistachio shell elements plays an important role in increasing performance
 
It has pistachio trees. Potassium should be consumed especially in the rainy years. Check
 
Have shown that pistachio trees have the highest elemental amount after nitrogen
 
Which is harvested annually from the soil is potassium. And the maximum amount of absorption
 
Potassium mainly occurs during the filling phase of the brain
 
In the following years, the absorbed potassium is consumed directly in the filling of the brain
 
They reach, but in the unfavorable years, the potassium absorbed from the roots is stored in other organs
 
Becomes. That is why the potassium concentration of the leaves in the year is lower than in the year
 
It is rewarding. Studies have shown that potassium uptake in fertile years over a full period
 
Brain growth is more than double the amount of potassium absorbed in infertile years. Fertilization
 
Suitable potassium for pistachio trees is the key to yield and increase yield in pistachio orchards
 
Is. Studies have shown that the highest amount of leaf potassium in August and September
 
It is observed every year at the same time as the seeds go to the brain or fill in the leaves.
 
Therefore, in this critical time period, the tree should not be deficient in potassium
 
Be. It is found that in pistachio trees the amount of potassium uptake from the soil is low
 
The most familiar with the practice of cutting and holding pistachios is its surface.
 
Potassium concentration in pistachio leaves in spring is below one percent. This concentration in
 
During the growth and development of the fruit is amazing, especially in July
 
September increases. Finally at the time of puberty and the end of the formation of skin and brain and
 
Completion of the growth period means approximately in September, the maximum absorption of potassium from the roots
 
We will have pistachios. Potassium concentration in leaves in October, ie the period after
 
Harvesting is suddenly reduced, so there is no need to apply potash fertilizer
 
Is not. Fertilization with potassium fertilizers increases the resistance of pistachio trees
 
To various stresses including salinity, drought and frost stress as well
 
Increase resistance to various pests and diseases. If potassium
 
Sufficient to provide the roots of trees with the number of spikes and seeds as well
 
The percentage of laughter and dry weight of seeds in pistachios will increase significantly.
 
Potassium deficiency is observed in most pistachio orchards and its main symptom
 
Burns the margins of the leaves. Another consequence of potassium deficiency is hypersensitivity
 
Sunburn and reduced degree of laughter of ripe fruits. Some shortcomings
 
Potassium is confused with salinity stress.
 
The difference between the two is that in salinity stress, necrosis of the leaf margins is present
 
does not have. Potassium can be obtained through sources of potassium fertilizers such as potassium sulfate
 
Chalkud face, solo potash for use in irrigation water and foliar spraying and
 
Potassium nitrate should be used as a foliar spray and irrigation water. Usually in
 
Pistachio orchards, about 80 to 100 due to the high need of trees in the closing stage
 
A kilogram of solo potash is consumed in 2 installments in irrigation water, at the same time
 
Now it is better in saline conditions of potassium nitrate fertilizer in 2 to 3 steps
 
Foliar application should be used in the closing stage of the brain with a concentration of 3 to 4 per thousand. Of course
 
The use of soloptas fertilizers and potassium nitrate depends on the storage of plant potash and
 
The use of potassium sulfate fertilizer in the form of chalk fertilizer. In textured soils
 
Heavy higher amounts of potash fertilizers due to higher uptake of potash in the layers
 
Soil is used.

ساختار آزمون PET

آزمون PET هر چهار مهارت زبان انگلیسی شما یعنی لیسنینگ، ریدینگ، رایتینگ و اسپیکینگ را ارزیابی می کند. ساختار این آزمون به شرح زیر است:

بخش اول (90 دقیقه): بخش اول آزمون PET مهارت خواندن و درک مفاهیم (reading comprehension) و همینطور نوشتن (writing) شما را به طور همزمان ارزیابی می کند. این بخش به 8 قسمت تقسیم می شود که در مجموع 42 سوال دارند. 5 بخش اول روی مربوط به مهارت ریدینگ و سه بخش بعدی روی مهارت رایتینگ متمرکز است. سوالات این قسمت شامل چند گزینه ای (multiple-choice) و پر کردن جای خالی (fill-in-the-blank) می شود. علاوه بر این از شما خواسته می شود که در بخش رایتینگ انگلیسی که یک داستان، نامه یا کارت پستال بنویسید.
