Greenhouse cucumber irrigation

<

It is well-known that fertilizer and water play a crucial role in the growth of vegetables, and for greenhouse cucumbers in winter, the requirements for water in different growing seasons are very strict, which directly determines the yield and quality of cucumber. I will introduce the irrigation technology below for your reference.

First, the planting period of irrigation must be made before the end of irrigation planting soil, soil moisture content should be appropriate. Colonization adopts a water-stable seedling method to enable the seedlings to be successfully planted and rooted.

Second, rooted shoots just grow new root tips, must be timely irrigation once rooted in small water, the water after planting 12 days -13 days.

Third, remind melon water when the young melon grows to 14 centimeters to 16 centimeters, it is necessary to promptly pour melon water, otherwise it will affect the yield and benefit of the whole growth period.

Fourth, the initial period of irrigation water when the root melon grows to 125 grams -150 grams can be harvested before irrigation, irrigation after harvest is conducive to increase production, can prompt the rapid growth of melons. Improper irrigation of this water will affect root melon production and succession of melon and melon growth.

Fifth, the low-temperature irrigation In general, the greenhouse winter cucumbers harvest root melon and the second melon when the outdoor low-temperature period, if the greenhouse is not high quality, without the corresponding measures of insulation and warming, can not guarantee the cucumber Normal growing temperature conditions, therefore, must be less watered.

Six, Yaoguagua irrigation This time greenhouse temperature is suitable for melon growth, so it is appropriate to increase the number of irrigation and irrigation volume, and increase the use of multi-element mixed fertilizer, the amount of 60 kg -70 kg per 667 square meters.

7. During the period of guaranty and melon irrigation, the daily fresh melon of 667 square meters will be between 240 kg and 250 kg, which will enter the guaranty period. During this period, the water requirement will increase significantly. Generally, the water will be poured from 4 days to 5 days, when the temperature is high. 2 days - 3 days poured 1 water. Temperature is not the main contradiction during this period, and the main contradiction is water and fertilizer problems. Therefore, this period of irrigation should ensure 2 days - 3 days and 1 water. With water-retaining fertilizer, about 667 square meters of multi-element mixed fertilizer is applied for about 50 kilograms each time.

8. In order to continue to have higher yields and benefits, the irrigation system in the later period must continue to adhere to irrigation and fertilizer and strengthen the implementation of comprehensive technical measures.
