Special growth regulator for peanuts in fruiting period

Abstract

The invention relates to the field of peanut cultivation techniques and in particular relates to a special growth regulator for peanuts in a fruiting period. The special growth regulator comprises 20-30g of paclobutrazol wettable powder, 2.5-3.0g of chitosan oligosaccharide, 50-100g of seaweed extract and 115-180g of saccharose. The content of chlorophyll of leaves, the leaf net photosynthetic rate and the root activity of the peanuts treated by the regulator in the fruiting period are obviously higher than corresponding contrasts, the leaf SOD (superoxide dismutase) activity and the POD (peroxidase) activity are both obviously higher than corresponding contrasts, the content of malondialdehyde is obviously lower than the contrast, and therefore, the regulator can be used for well eliminate oxygen free radicals and delayin g senescence. By utilizing the special growth regulator, the leaf nitrate reductase activity, the glutamine synthetase and glutamate synthase activities are obviously improved, the leaf sucrose synthetase and sucrose phosphate synthase activities are improved, and the accumulation of pod dry matters and compounds of nucleus protein and fat are facilitated. The peanut pod yield is obviously increased, the production increase reason is that the weight of single fruits is obviously increased, the full fruit rate is increased, and the double-kernel fruit rate and the kernel yield rate are greatly increased simultaneously.

Description

[0001] technical field [0002] The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut pod setting stage. [0003] Background technique [0004] In the main peanut producing areas, peanut production is often threatened by excessive growth or even lodging, which seriously affects the yield and quality of peanuts. At present, the production mainly relies on spraying plant growth regulators to control the excessive growth of peanuts during the peak growth period. As a high-efficiency, low-toxic plant growth retardant and broad-spectrum fungicide, paclobutrazol has become an important chemical control measure in agricultural production. However, spraying paclobutrazol can easily lead to premature aging of peanuts in the later stage of growth, and will also affect the further improvement of yield and quality. Therefore, it is urgent to invent a novel foliar growth regulator for peanut pods, which can not only co...
