How to prevent melon from suffering?

Answer: 1. Improve lighting conditions: When protecting melons in protected form, cover the no-drop film and keep the film clean. Try to get the maximum light transmittance and make the soil accumulate more heat. Release the reduced plants, properly dilute the plants, pay attention to pruning, tying the vines, picking the heart, and comprehensively improve the lighting conditions in the field.

2, control temperature: melon in the melon period, large temperature difference between day and night, is conducive to the accumulation of nutrients during the day and reduce nighttime consumption, sunny daytime temperature should be controlled at 26 °C-28 °C, nighttime temperature should be controlled at 10 °C-12 °C. In case of abnormal weather, it is necessary to take remedial measures in time.

3, scientific operation of fertilizer water: to apply more organic fertilizer, especially to apply adequately decomposed and harmless treatment of chicken manure and cake fertilizer and other high-quality organic fertilizer, do not apply too much nitrogen fertilizer. Watering is reasonable, keeping the soil with enough water, watering should be a small number of times, it is not easy to water on rainy days, it is better to water on sunny days.

4, retain the appropriate melon node: do not leave the root melon, the general bitterness is mostly on the root melon, because the root melon is close to the root of the plant, the effective function leaves are few, the nutrient conditions are poor, if the fruit development is in the low temperature period, the light is insufficient In the case of malnutrition, it is easy to make the melon skin thick and bitter. But the melon node can't be too far from the root.

5, can not hurt the roots, timely planting: during planting and field management, do not hurt the roots or minimize the root damage, to avoid bitterness.

6, the correct application of sitting melon, suitable harvest: sit gualing every 5 grams of water 2-3 kg (diluted 400-600 times), the application concentration is related to the ambient temperature, the temperature is high, the concentration should be appropriately reduced; temperature Less than 15 ° C is not suitable for application. After applying the melon, you must wait until the melon is fully mature before harvesting, so that the bitterness is fully transformed. It is recommended to reduce the administration of sitting guar or plant growth regulators.

If grafting is cultivated, it is necessary to pay attention to the choice of rootstock varieties.
