First, strictly control the retention of melons. Bitter cucumber can be inherited, so when the cucumber is about to mature, select the surface part of the melon to taste, choose no bitter melon seeds.
The second is balanced fertilization. Seedling stage should control the use of nitrogen fertilizer, and then gradually increase the amount of nitrogen fertilizer, to the flowering period, the ratio of cucumber to nitrogen, phosphorus, potassium absorption is basically 5:2:6, excessive nitrogen fertilizer or phosphorus, potassium too easy to produce bitterness .
The third is to avoid high temperatures. When the ground temperature exceeds 30°C for a long time, bitter melons will increase and the temperature should be controlled.
The fourth is to avoid drought. In drought, it is relatively easy to produce bitter melons. Water should be promptly provided to avoid drought.
Fifth, active prevention and control of pests and diseases. If the production environment of cucumbers is poor and the pests and diseases are serious, the bitter taste of cucumbers will increase. For cucumber disease, early spraying protection.
