Melons are originally sweet and refreshing, but sometimes the melons you buy are bitter. Why is this? Today I will focus on introducing to you what causes bitterness in melons and how to prevent bitterness in melons. #2020金米氰 plan#What’s the matter with the bitterness of melon?

1. High temperature and drought: Muskmelon is usually planted in March and April. When it is still growing, it enters the high temperature period in late spring. At this time, the soil temperature becomes higher, and the roots of the cantaloupe seedlings The ability to absorb water is weakened, resulting in slow growth. Slow-growing melons cannot easily absorb water and nutrients, and a large amount of bitter elements accumulate in the melon body, eventually making the melon no longer sweet.

2. Insufficient sunlight: Sunlight is indispensable for fruits during their growth. If there is insufficient sunlight, the fruit will not be sweet enough. If the melon is not sweet, it may be because there is not enough sunlight, or it may encounter continuous rainy days. Long-term rain will damage the roots of the melon seedlings, making it difficult to store sugar during its growth, so it will not be sweet.

3. Long-term rain: The growth environment of cantaloupe is also very important, especially in the mature stage, which requires a significant temperature difference. It is best to add some water to the roots of the melon vine when it is sunny during the day and cool at night. The sugar content of mature cantaloupe in this environment with great temperature difference is high. However, in the case of long-term rainy weather, the sugar content of cantaloupe is low, many bitter elements cannot be converted, and the taste is bitter. This kind of bitterness is generally relatively uniform. This kind of cantaloupe can Eat in moderation.

4. Excessive application of nitrogen fertilizer: Melons tend to have a bitter taste when mature.

5. Planting too late: Especially for older melon seedlings, the roots are severely damaged when transplanted, and bitter melons are easily formed.

6. Bitterness caused by ripening: Many melons are not ripened naturally, but are ripened with chemicals. Unlike bananas and kiwis, cantaloupes also contain a large amount of bitterness on the skin of unripe melons. During ripening, these bitter elements cannot be completely converted and will be deposited in the pulp, resulting in a bitter taste when eaten. It is not recommended to eat this kind of cantaloupe.

7. Pesticide residues: There are also many insect pests during the growth process of muskmelons, especially when they are about to mature. The muskmelons will emit some fragrance, which attracts insects. Therefore, during the maturity period of muskmelons, there will be Spray some pesticides. Excessive pesticide residues will also make the pulp taste bitter. This bitterness is generally uneven and has a bitter taste in scattered small spots.

8. The melon base will be bitter: The flesh of the melon is sweet, but the melon base is generally bitter. The reason is that the melon base contains cucurbitacin B, and the pharmacological effect of cucurbitacin B is to treat Dampness, heat and poison are abundant, and it can assist in the treatment of chronic hepatitis. However, the cucurbitacin B contained in the melon pedicles should not be eaten, otherwise it will cause poisoning. #白城新农人#How to prevent melons from becoming bitter?

1. Improve light conditions: When cultivating melons in protected areas, cover them with a drip-free film and keep the film clean. Try to achieve maximum light transmittance so that the soil can accumulate more heat energy. Release and reduce plants, plant appropriately sparsely, pay attention to branch pruning, tying vines, and topping, and comprehensively improve field lighting conditions.

2. Control temperature: The temperature difference between day and night is large during the melon expansion period, which is conducive to the accumulation of nutrients during the day and reducing consumption at night. On sunny days, the daytime temperature should be controlled at 26℃~28℃, and the nighttime temperature should be controlled at 10 ℃~12℃. In the event of abnormal weather, remedial measures must be taken promptly.

3. Scientifically manage fertilizers and water: Apply more organic fertilizers, especially high-quality organic fertilizers such as fully decomposed and harmlessly treated chicken manure and cake fertilizers. Do not apply too much nitrogen fertilizer. Water properly and keep the soil with sufficient moisture. Water in small amounts and frequently. Watering is not easy on cloudy and rainy days. Watering should be done in the morning on sunny days.
