Abstract

The invention relates to the technical field of peanut culture and in particular relates to a growth regulator specially used in mature periods of peanuts. The growth regulator comprises 5-10g of chitosan oligosaccharide, 50-80g of seaweed extract, 150-180g of monopotassium phosphate, 60-70g of thiophanate methyl and 160-235g of sucrose. The growth regulator has the beneficial effects that the peanuts treated with the regulator in the mature periods have obviously higher leaf chlorophyll contents, net photosynthetic rates and root activities than control groups, have obviously higher leaf SOD (superoxide dismutase) activities and POD (peroxidase) activities than the control groups and have obviously lower malondialdehyde contents than the control groups, indicating that the regulator can well remove oxygen free radicals and delay senescence; the regulator obviously promotes accumulation of dry matters of pods and synthesis of proteins and fat of seed kernels and has important function of promoting increase of yield and improvement of product quality.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut fruit-full stage. Background technique [0002] In the later stage of peanut growth, especially under film-covered cultivation conditions, premature senescence will occur. At the same time, peanut leaf spot is more common. In severe cases, it will cause leaf defoliation and early plant withering, which will affect nutrient accumulation and lead to insufficient pods, reducing kernel yield and oil content. , easy to drop fruit and seeds to germinate when harvested. The problem of premature senescence in the later stage of peanut growth can be solved by topdressing the leaves. However, the single spraying of foliar fertilizer has little effect, and the oxygen free radicals in the body cannot be effectively removed. Therefore urgently need to invent a kind of growth regulator that can not only effectively scavenge oxygen free radic...
