The "big belly button" of zucchini is a physiological malformation. Generally, it is easy to appear after the zucchini has fallen flowers. The navel is particularly large and bulges outwards. The commodity is poor. The main reason for the formation is improper use of wiping medicinal agents. To prevent the "big belly button" of zucchini, pay attention to the following three points:
Master the time to wipe the melons. Most of the flowers of zucchini are fully open at 4 to 5 in the morning. It is a bit late to wipe the melons in the daytime. Therefore, the time for mopping melons should be advanced appropriately, and it is most suitable when the flowers seem to not bloom the night before.
To master the concentration of mop melon medicine commonly used in the production of mop melon medicine is generally gibberellin. The concentration of wiping melon medicine should change with the temperature. It should be increased when the temperature is low, and should be decreased when the temperature is high. If the temperature in the shed is high, the vegetable grower doesn't know that reducing the concentration of the melon medicine will cause the zucchini to form many "big belly button" fruits. In addition, it is necessary to make the area of ​​wiping the melon as large as possible and the concentration of the agent as small as possible. In this way, the ideal effect of sitting on the melon can be achieved without phytotoxicity, forming a "big belly button".
After mastering the correct method of wiping melons, apply a brush to the symmetrical positions of the young zucchini melons to avoid skewed, large or curved melons.
