Plant growth regulator comprising gibberellin and forchlorfenuron

Abstract

The invention relates to a plant growth regulator comprising gibberellin and forchlorfenuron. The plant growth regulator comprises, by mass, 0.2% of gibberellic acid GA4+7, 1.0% of forchlorfenuron, 5%to 25% of a surfactant and the balance of auxiliary materials. The plant growth regulator comprising gibberellin and forchlorfenuron can effectively promote the fruit setting of the jujube tree, increase the weight of the single fruit, increases the yield of the jujube tree and has obvious yield increasing effects. The plant growth regulator is sprayed once in the early flowering stage, young fruit stage and fruit expansion stage. The active ingredients gibberellin and forchlorfenuron have a use dosage of 1.0 to 1.3 mg / kg. 450 kg of water per hectare is used. The plant growth regulator is uniformly sprayed to the canopy.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology in biology and new medicine, and belongs to the production technology of high-quality, high-efficiency and safe production of plant growth regulators. Specifically, the present invention relates to a plant growth regulator containing gibberellin and forchlorfenuron. Background technique [0002] Plant growth regulators are a class of pesticides used to regulate plant growth and development, including synthetic compounds with similar effects to natural plant hormones and natural plant hormones extracted from organisms. Ordinary plant growth regulators have single components and a narrow range of use, resulting in single functions and ineffective yield-increasing effects. For target plants, plant growth regulators are exogenous non-nutritive chemical substances, which can usually be transmitted to the site of action in plants, and can promote or inhibit certain links in their life processe...

AI Technical Summary

Problems solved by technology

Traditional plant growth regulators have large dosages, high residues, serious environmental pollution, poor safety in use, and low utilization rates, which do not meet the development needs of ecological agriculture.
