How is the bitter melon of cucumber formed?

The bitter melon of cucumber is related to the variety first. Generally, the dark green color of the leaf is more susceptible to bitter melon than the lighter color of the leaf. Improper cultivation or cultivation environment will increase the appearance of bitter melon.
1. Excessive application of nitrogen fertilizer. Because the plants are long due to excessive nitrogen fertilizer, the melons are not neat, and the melons on the side branches and weak plants are prone to bitterness.
2. Melon strips grow slowly. During the low temperature and low light period, the roots or activities of cucumber are damaged and hindered, the water absorption and nutrient are small, and the melon strips grow slowly, and more bitter taste is accumulated in the root or lower melon.
Bitter melon caused by high temperature. Cucumbers cultivated in wintering and winter springs enter the high temperature period in late spring, or due to root senescence, soil moisture is high, root absorption capacity is weak, nighttime temperature is high, melon strips grow slowly, and more bitterness is accumulated in melon strips.
