1. The fact that cucumbers have flowers without melons is mainly due to the imbalance of cell division in cucumber plants, which leads to the opening of male flowers but not female flowers, which makes it difficult to form melons. If the vines grow mad during the growth of the cucumber plants, the plants will only open the male flowers without opening the female flowers, or only open a limited number of female flowers.
Second, the prevention and control of cucumber plants only open male flowers without causing female flowers and cause non-sprouts, is to strictly control the melon mad growth, to ensure that cucumber plants grow thick and robust, to enhance the cucumber plant body "extracts" and female and male flowers open together ability.
The specific method is: When the cucumber plants grow more than 4 true leaves, melon vines grow about 30 to 40 cm long, with three millionths of the plant growth regulator ethephon diluent, or nitric acid, three 10 to 10 grams of deca-ol, or 10 grams of pro-glucagon (above, one of the above agents can be used), then 50 to 70 kilograms of water and mix well, spray evenly on cucumber plants 1 or 2 times, it can be effective Solve the problem of "infertility" that cucumbers cause because they only open male flowers.
