The invention relates to a biological
regulator with a function of increasing fruit setting percentages of fruit vegetables and a method for preparing the biological
regulator. The biological
regulator comprises, by weight, 6-10 parts of 2, 4-dichlorphenoxyacetic acid, 6-8 parts of diethylaminoethyl hexanoate DA-6, 7-10 parts of
forchlorfenuron, 3-5 parts of
sodium nitrophenolate, 0.5-1 part of falling preventive elements, 4-5 parts of
gibberellin, 8-10 parts of benzylaminopurine, 3-5 parts of dispersing agent
ethylene-
vinyl acetate copolymers, 2-3 parts of emulsifiers OP-10, 4-6 parts of antifreezing agents
ethylene glycol and 100-150 parts of absolute ethyl
alcohol. The biological regulator and the method have the advantages that the biological regulator is wide in acting surface and canbe applied to multiple fields;
photosynthesis,
respiration and substance absorption and translocation of plants can be regulated and controlled, physiological procedures for
signal transduction,
stoma opening and closing, osmotic adjustment,
transpiration and the like can be adjusted, and accordingly growth and development of the plants can be controlled; the biological regulator is low in usage,high in speed and benefit and little in residual
toxicity, and only needs to be sprayed once for most fruit vegetables in each season according to set time; the biological regulator rarely can be affected by environments, the fruit setting percentages of the fruit vegetables can be increased by the biological regulator, use
modes for the biological regulator are easy and convenient to operate, and the time and labor can be saved.
