The importance of cucumber production under plastic tunnels
Cucumber is one of the most consumed plants by many consumers, in addition to that it generates a great income for farmers. It is known that cucumber is a summer crop, which is grown in two loops, namely, the summer loop and the autumn loop. As for the cultivation of cucumbers under protected greenhouses, it is cultivated throughout the year in several consecutive loops and thus appears In the markets throughout the year, in addition to the fact that cucumbers are income-generating crops and very profitable for many farmers.
Environmental conditions suitable for cucumber cultivation.
Cucumber plants need different environmental conditions and care must be taken to provide those appropriate conditions to obtain a good crop and also good fruits suitable for quick consumption, thus raising farmers’ income. Among the most important of these environmental conditions are as follows.
cucumber growing temperature celsius
The temperature suitable for cucumber cultivation is one of the most important environmental conditions that must be available for cultivated plants. The most suitable temperature for cucumber growth is 15-35 degrees Celsius, and lower temperatures than this rate leads to delays in the emergence of seedlings, and an increase in temperature above this rate leads to To burn cucumber leaves.
Note that higher temperatures than the appropriate rate with the long day leads to the emergence of a large number of male flowers, and also a lower temperature than the appropriate rate leads to the emergence of many feminine flowers. Also, the increase in temperature above the average with low humidity leads to a delay in the period necessary for the appearance of flowers. Feminine, and drought leads to an increase in male flowers.
Second: the light.
Good lighting leads to a decrease in the leaf area and an increase in the number of branches, thus increasing the total area of the leaves, and thus increasing the amount of the resulting crop, while the increase in temperature with the length of the light period leads to the production of male flowers in large numbers, and the decrease in temperature with the short duration of lighting leads to the production of flowers Feminine, so the greenhouse must be washed during winter to provide the appropriate degree of lighting.
The humidity should not be less than 70%, and the most appropriate humidity is 80-90%, knowing that the increase or decrease leads to the impact on the quantity of the production of fruits with a sharp decrease, and attention should be given to providing ventilation constantly so that fungal diseases do not appear.
