Prevent frost from pistachio trees

1- Do not do early pruning

Basically, if pruning is done before Iranian Pistachio the onset of cold and frost, activity

 

Physiological cells in the incision area are increased and sensitivity to cold is high

 

goes. Therefore, pruning operations can be postponed until after the frost season

 

Be.

 

2- Failure to carry out land harvesting operations

Pre-frost tillage operations lead to large and abundant pores

 

It becomes dust. Since the air has poor thermal conductivity and conductivity, the soil

 

The larger the pores, the weaker the potential for guidance and storage

 

They have heat in them. It is therefore recommended to prevent tillage operations and

 

Soil compaction should increase the transfer and storage of heat in the soil.

 

3- Irrigation operations in dry soils before frost

Dry soils have more porosity than wet soils

 

They have more air and less heat storage and transfer capacity.

 

Therefore, in dry years, pre-frost irrigation seems to be useful

 

So that by maintaining moisture, he became familiar with the operation and had pistachio seeds

 

Soil at field capacity, heat transfer potential and storage at a depth of 30 cm

 

Soil increases due to the specific heat capacity of water. On the wet side

 

Dry soils lead to darker soils and this in itself leads to

 

The sun absorbs more of the sun"s energy and warms it.

 

4- Weed removal

Removing weeds from the garden floor and tree legs leads to more light energy absorption

 

The sun is made by the soil.
