Good climate for saffron cultivation
Saffron is a semi-tropical plant and it is well tolerated in places where it is mild and dry in summer. The resistance of saffron is high in cold weather, but since its growth coincides with autumn, winter and early spring, we naturally need a good, moderate air.
During the sleep or rest period of the plant (summer) rain or irrigation is harmful to it, so cultivation and its work in the regions of Guilan and Mazandaran and the warm southern regions of the country is not common. Sunny and non-tropical trees that are not exposed to cold winds are also suitable for saffron growth. However, in some villages of Birjand and Qa'in under the shade of bushes of barberry and almond trees, which are irrigated in the summer, are planted.
The maximum temperature of this plant is between 40 to 35 degrees Celsius and at altitudes between 1300 and 2300 meters above sea level. Proper cultivation of saffron: Since the saffron bulb has a relatively high (5-7 years) Stayed Ground soil should be lightweight or a combination of sand and clay that onion can be able to withstand regional conditions in addition to food supply. Therefore, in order to grow the plant properly and produce a high quality and desirable fertile soil and Preferably drained without a tree with soil (loamy, limy, clay and sandy) and limestone with pH ranging from 7-8 to acidic, poor and wet ground.
Normally, the first weed of saffron is after flowering, and the second is, if necessary, about one month before the third water. In the case of chemical warfare with field weeds, it should be noted that since the effect of these herbicides on the plant has not been tested, it is also necessary to avoid the use of herbicides during growth of bushes in grapevines. Saffron crop operations: According to It is not possible to reproduce the saffron crop by racial breeding. Therefore, in order to increase the yield of the product and its quantitative and qualitative improvement, the following factors should be applied:
1. The selected land for planting saffron must be fertile and rich in food and organic.
2 - Coarse and healthy bulbs free of any diseases and contaminations for field cultivation.
3 - A row of jobs instead of a cluster gives a better result and makes machine operation easy on the farm.
4. Use dried and cooked onions in a dry, cool and ventilated condition.
5 - During the summer rest of the saffron plant, avoid irrigation.
6. In the depth of planting of bulbs, be careful not to be less in the cold areas of 20 to 15 cm and in temperate regions of 15 to 10 cm.
7 - It is possible even during summer sleep with weeds to fight.
8 - Because each year the bulbs approach the surface of the soil, adding a layer of 2-3 centimeters from the soil, fertilizer, and ash will further protect the bulbs from environmental stresses and, at the same time, provide more nutrients to the plant.
9 - At the time of preparing the land, it is not necessary to add any animal fertilizers to the chemical fertilizers that have already been indicated in terms of the amount and time of consumption.
10 - After irrigation, it is necessary to completely break down the ground so that the flowers can all be removed from the soil. Finally, it should be noted that the depth of the crackdown is not such as to damage the saffron bulbs.
11. Fighting rodents, especially of all types of mice, is important. Any negligence in this regard results in the loss of crop and the placement of mice on the ground.
12 - Flower picking in the first hours of the day (4 to 9 in the morning), when the flowers are buds, should be done.
13. In the drying of flowers, care must be taken to preserve the color and aroma of saffron.
14 - The best method for drying saffron is the Spanish tanning or drying process, which is carried out by a heater and an aliquot.
15 - Finally, the saffron should be kept in a container in a metal, tin or glass container, away from light and moisture and heat.
