1. Causes of suffering

1. High-temperature melons are planted in the spring, and the flowering and fruiting stage has entered a high-temperature period, and the root system cannot adapt for a while. Absorptive capacity is weakened, nutrient moisture is reduced, and bitterness accumulation in melon is too high, it will cause bitterness.

2. Insufficient light and rainy days without sunlight, leaf photosynthesis weakens, nutrient accumulation is less, water is more, sugar is reduced. And the absorption capacity of the accumulated rain root system is reduced, it is less sweet, and bitter taste can not be converted.

3. For other reasons, too much nitrogen fertilizer is applied, and it is easy to suffer after maturity. The transplanted seedlings are too old, and the transplanted roots are more damaged. If they are not absorbed well, they will suffer. Or for transportation and storage, picking the unripe fruit and then ripening the fruit with medicine will cause bitterness. Most guadi will become bitter due to cucurbitacin B.

2. Preventive measures

1. Early sowing and replenishing water can be properly sowed early. Through small arch shed seedling raising or greenhouse seedling raising, the flowering and fruiting period can be advanced by half a month or a month, which can avoid high temperature and drought affecting root absorption. In case of high temperature and drought, water the roots at night to protect the root system and maintain the vitality of the root system. You can choose high-quality varieties with strong roots and high temperature resistance.

2. The land selection and drainage should be planted in the sunny slopes with enough direct sunlight, not in low-lying rice fields. During the rainy season, multiple drainage channels should be dug to ensure drainage. After the rain, you can sprinkle grass and ash on the wetland to absorb moisture and replenish and strengthen the roots, so that the root system will be less damaged and the normal absorption and utilization ability will be maintained.

3. Other methods of fertilization can be applied a little more when growing vines in the early stage, and in the later stage, as long as the leaves are thick green without yellowing, they can not apply nitrogen fertilizer, or apply a little nitrogen fertilizer.
