How to prevent and cure cracked cantaloupe?

What caused the cracked cantaloupe? How to prevent and cure cracked cantaloupe? Please also know the netizens to help introduce cantaloupe crack melon will occur after sitting to the early stage of milk ripening, in the cantaloupe expansion period is more common, the damage is also more obvious. At the initial stage, many small longitudinal cracks are formed, which gradually become obvious cracks, and finally develop into large wounds, some of which can be as deep as the flesh part of the melon. In the middle and later stage, the crack can grow glue, or turn brown because of miscellaneous bacteria infection, and some rot. Therefore, the farming network sorted out the causes and control methods of cracked cantaloupe, which are listed in detail below for netizens' reference. The reasons for the cracking of cantaloupe are as follows: first, the growth of Hami melon seedlings is not consistent during planting, which leads to the inconsistency of flowering and setting time, and the development time of young melons among plants is different, the same management, the same watering, so that the early sitting part of the melon cracking. Second, water control for a long time after cantaloupe sitting, or sudden pouring of water after a long period of lack of water in the weather, or heavy rainfall, the growth and expansion of melon flesh tissue is too fast, and the growth rate of melon flesh and peel is not synchronized, resulting in cracking melon. Third, Hami melon grew in high humidity environment for a long time in the later stage, and suddenly decreased the air humidity due to management or climatic reasons, resulting in melon epidermis cracking. Fourth, cantaloupe cracks due to uneven light exposure for a long time, suddenly changing the original direction of light. It is easy to occur under the condition of strong sunlight when planting in open field. Prevention and control methods of cracked cantaloupe: first, rational watering during the melon-forming period of Hami melon to avoid sudden heavy watering after long-term water control or serious water shortage. Method 2. Balanced fertilization was applied to Hami melon, phosphorus and potassium fertilizer was applied, and fully mature organic fertilizer was applied to improve plant disease resistance. Method 3. When 2-3 cracked fruits are found in the whole melon field, pliers can be used to break the base of the vine (the first to second nodes, when the growth is strong, the broken parts begin to bulge after 3-4 days and return to normal), remove the lower leaves, or dig up the root system, retain one, and cut the rest, so as to weaken the plant growth and prevent excessive water absorption from causing fruit cracking. Method 4. When cantaloupe is produced in winter, the daily average temperature should be kept above 15 ℃, and the temperature should be heated temporarily at night in case of sudden cold wave. Method 5. Complete the ditch system to ensure smooth drainage. It is necessary to dig deep drainage ditches, do a good job in the ditch system, and often clean up the ditch system, especially in the fruit period to ensure smooth drainage of melon fields, prevent prolonged drought, rain and sudden watering, and root systems absorb a large amount of water, resulting in excessive water absorption of fruits, and fruit cracking due to increase in volume. Method 6. In the cantaloupe plantation, the drainage ditch should be deeply dug, the ditch system should be well matched, and the ditch system should be cleaned frequently, especially in the fruiting period, the drainage of the melon field should be ensured, the long drought, rain and sudden watering should be prevented, and the root system should absorb a large amount of water. cause the fruit to absorb too much water, and the volume increases and the fruit cracks. Method 7. Hami melon was artificially pollinated. Because most of the fruits contain growth hormones such as swelling, the fruits pollinated by artificial pollination are lighter than those with Guoling. For example, when the fruit setting condition is bad, which affects the fruit setting, it should be used to pay attention to: the concentration used should be strictly prepared according to the "instructions". The concentration of its configuration is different at different time and temperature. When spraying or applying Guoling, the ovary of the female flower should be evenly treated, and the criteria for dealing with the female flower should be selected: the ovary is well developed and sturdy, and the flowering should be controlled on the same day or tomorrow. Because the incidence of fruit dehiscence in the sturdy female flowers blooming in these two days is much lower than that in the small female flowers in the late blooming state. Method 8. Rational pruning of Hami melon to make rational distribution of nutrients. Principles to be grasped when pruning cantaloupe: timely, moderate and diligent pruning. Try to avoid rebranching in the late fruiting stage, because the nutrient supply of the plant is reasonably distributed, and after rebranching, the nutrient supply of the plant is uneven, resulting in a large amount of nutrients transported to the fruit, resulting in fruit cracking. Method 9. When doing farm work in melon orchard, it is necessary to avoid fruit cracking caused by collision and extrusion of human or other factors. Harvest should be carried out when the temperature of the melon is low in the morning, but there is no dew on the surface of the melon.
