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.
