What's the best temperature for a cucumber
Many grow cucumbers, which are poorly grown, small, flowerless and small. Many of these cases are not about fertilizers and water, but rather are not controlled within the appropriate range. The cucumber requirements are fixed and different temperatures are required at different stages of growth, and all temperature values are clearly stated in this paper in plain language, without unnecessary modifications, and can be implemented directly。
First, the temperature of the cucumber seed sprouts. Cucumber seeds are fertilized, with the most appropriate temperatures ranging from 25 to 30 degrees. Within this temperature range, seeds are seeded fast and well. The minimum cucumber seed sprout temperature is 15 degrees, the temperature is below 15 degrees, the seed does not germinate and rots directly in the soil. The highest tolerance temperature for cucumber seeds is 35 degrees, with temperatures above 35 degrees, where seed sprouts are inhibited, the guacamole is weak and the later survival rate is low. Households grow cucumbers, where the temperature of the soil can be measured and delayed if the temperature does not reach it, or where the covering film increases the temperature。
Then speak of the temperature during the growth of cucumber seedlings. The suitable temperature for the seedlings is 22 to 28 degrees in the daytime and 15 to 18 degrees in the night. The growth of cucumber seedlings requires a certain temperature difference between day and night, which is most appropriate at 8 to 10 degrees. The temperature is below 20 degrees during the day, and the growth of the seedlings slows down and leaves are reduced. At temperatures above 30 degrees in the daytime, the seedlings will grow up, decompose, thinn the leaves and make melons difficult at later stages. At night temperatures of less than 12 degrees, seedlings stop growing and are prone to freezing. At night temperatures are higher than 20 degrees, the seedlings will have only long leaves that do not have roots and will be less resistant to disease. The field seedlings can cover the membranes with low temperatures, and the tubers can control the temperature by venting through switches。
Next is the temperature of the cucumber flowering cucumber period, which directly affects production. Cucumbers open cucumbers with the best temperature during the day being between 25 and 30 degrees and between 16 and 20 degrees at night. The temperature is below 20 degrees during the day, the amount of cucumber blooms is reduced, pollen activity is low and it is not normal to pollinate, and there are cases of flowering without cucumbers. At temperatures above 35 degrees in the daytime, cucumber pollen loses activity, flowers fall easily and the resulting melon is deformed. At night temperatures are below 13 degrees, cucumber bars grow slowly and mature long. At night temperatures are above 22 degrees, cucumbers tend to grow and their nutrients are provided only with leaves and no bars, resulting in a small amount of melons and deguados. Cucumbers are grown in the open and can be properly shaded at high temperatures, and small arch sheds can be built at low temperatures。
The temperature management of cucumbers varies from one plant to another. In order to plant cucumber in the field, the choice is to plant at temperatures of 15 degrees or more, and the overall long-term temperature remains between 20 and 30 degrees. The cucumbers are grown in large sheds, which are ventilated at temperatures above 30 degrees in the day and below 15 degrees in the night. The cucumbers are planted in the balcony basin, where they are ventilated and the light is stable, so that the balcony temperature is not so high and so low. Cucumbers are grown in the spring, with a focus on the prevention of cold temperatures, and in the autumn, on the prevention of high temperatures。
Many grow cucumber at inappropriate temperatures and do not know how to adjust. In cases of low temperatures, ambient temperatures can be increased by covering membranes, constructing arch sheds and choosing to water them at noon. When the temperature is high, the temperature can be reduced by covering it up, increasing ventilation and watering it early and late. The cucumber water should also be applied to the temperature, with more water being poured at high temperatures, and less frequent water being poured at low temperatures to avoid excessive soil temperature fluctuations。
Finally, cucumber cultivation remembers three stages of temperature. Euphoria temperatures range from 25 to 30 degrees, seedlings range from 22 to 28 degrees during the day, 15 to 18 degrees during the night, flowering melons range from 25 to 30 degrees during the day and 16 to 20 degrees during the night. If the temperature is kept above, the cucumber can grow, grow and grow normally。
This paper is based on lessons learned from actual cultivation and is not exaggerated and is suitable for household cultivation, field cultivation, and shed cultivation. Under this temperature standard, the success rate of cucumber cultivation will increase significantly and there will be no growth problems due to temperature。
