The growing period of greenhouse cucumbers is longer. In order to seize high yields, it is necessary to cultivate robust plants in the early stage of cucumber growth (from the time of colonization to the pre-harvest period). Based on my own planting experience, the author summarizes the pre-management into four words: "One Guarantee, Two Covers, Three Smelts, and Four Links."
One guarantee is to maintain a certain temperature before planting after planting, and it is best to keep it at 28 to 30°C during the day and 15 to 18°C ​​at night. The method of insulation is to close the tuyere.
The second cover refers to the sunny and warm weather. In order to prevent the temperature in the shed from being too high and to reduce the water transpiration of the seedlings, appropriate shading should be done with grasshoppers or shade nets at noon.
Three refining means that after easing the seedlings, it is mainly used for training plants. The temperature during the day is 25-28°C and 12-15°C during the night. After pouring the larvae, the water is generally not watered before the squashing. Promotes robust plants and prevents leggy.
Sitong refers to the need to strengthen ventilation during the hardening period, reduce the humidity in the shed to reduce the risk of morbidity, and to leave vents in the shed at night when the temperature is high.
