In natural conditions, cucumbers have more karma, which wastes nutrients and affects yield. Increasing female flowers in cucumber is an important way to increase cucumber yield. The specific method is as follows: When spraying cucumber leaves the first true leaf of the cucumber, the cucumber plant can be sprayed with an ethephon aqueous solution of 120 mg per kilogram, and the amount of spraying can reach the wet leaves, and the spray can be sprayed once a week later. Spraying ethephon can not only increase the number of female flowers, but also can inhibit plant leggy. Naphthyl acetate sodium salt in the cucumber grows 3 true leaves, with 100 mg per kilogram of naphthalene acetate sodium salt solution spraying cucumber plants, can increase the number of female flowers 3 times, and can control the male flower over-exposure. Spraying triiodobenzoic acid and sulphanic acid hydrazine at the cucumber seedling stage, spraying 250 mg/kg of triiodobenzoic acid aqueous solution and 250 mg/kg of cis-butane succinic acid hydrazine aqueous solution to cucumber plants can significantly increase the number of female flowers. , Reduce male flowers, so as to achieve the purpose of increasing production and improving efficiency.
