Problems solved by technology

[0006] At present, the regulatory substances have a single composition and a single function, which is not conducive to comprehensively realizing the regulation of the differentiation of male and female flowers, improving the quality of flowers, prolonging the life of pollen, promoting pollen germination and fertilization, increasing the synthesis of dry matter and accumulating in seeds, so as to achieve high seed yield, high quality purpose
In addition, if a single-function regulator is applied separately or simultaneously at different stages, it will increase labor intensity and cost, and also increase the difficulty of on-site scientific and precise preparation, making it difficult to guarantee the desired effect.

Abstract

The invention discloses a regulating agent for increasing the yield of vegetable seeds and an applying method and application. The compound regulating agent is composed of a regulating agent special for male parents and a regulating agent special for female parents. The compound regulating agent is applied at different growth stages of cucumbers, the yield of cucumber seeds can be increased, the quality of the seeds can be improved, and the advantages of being easy and fast to apply are achieved. The regulating agent is beneficial to regulating and controlling differentiation of female flowers and male flowers, improving the quality of the flowers, prolonging the service life of pollen, promoting pollen germination and fertilization and improving synthesis of dry matter and seed accumulation so that the aims of the high yield and high quality of the seeds can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a control technology for vegetable seed production. More specifically, it is a regulator, application method and application for increasing vegetable seed yield. Background technique [0002] In the process of vegetable breeding and seed production, plant sex differentiation is an important link that affects the number of male and female flowers of the male parent and female parent. Controlling the sex differentiation of plants is of great significance. In monoecious and dioecious plants, if To harvest seeds and fruits requires a large number of female flowers or plants. Environmental conditions such as nutrition, temperature, sunshine length, light quality, light intensity, water supply, and air composition all have certain effects on plant sex differentiation. Generally speaking, sufficient nitrogen nutrition, higher air and soil temperature, lower air temperature (especiall...
