In cucumbers cultivated in open and protected areas, some bitter cucumbers sometimes appear. This is caused by a substance called "Momordica charantia." The content of momordicin differs depending on the variety and cultivation conditions and can be controlled artificially. Fertilization should be reasonable: seedling stage should be controlled by the application of nitrogen fertilizer to avoid plant growth. With the growth of plants, the amount of nitrogen fertilizer can be increased to the peak of flowering, but not excessive. Excessive nitrogen fertilizer will make the plant growth and development unbalanced, not only cause leggy and fruiting, but also increase the proportion of bitter melon. To avoid low temperature or extreme high temperatures: When the ground temperature is below 13°C, the absorption of nutrients and water is affected due to the decrease of the permeability of root cells. At this time, there will be more bitter melons. When the local temperature reaches a high temperature above 30°C for too long, the proportion of bitter melons will also increase. Avoid drought: In the summer when the temperature is high and the soil moisture is less, the plants will experience "physiological drought" and appear bitter melon. Reasonable irrigation: cucumber roots into the shallow soil, can not absorb the deep water, it requires a sufficient amount of water plow; the same time, cucumber leaves large and thin, large transpiration, it requires a large air humidity, in order to reduce evaporation. To regulate the microclimate in the field with hot water at high temperatures, it is often necessary to maintain sufficient moisture in the soil so as to “eat less mealsâ€, but it should also pay attention to the amount of irrigation.
