Special growth regulator for peanut pod setting

Abstract

The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut pod setting stage: paclobutrazol wettable powder 20-30 g, chitosan oligosaccharide 2.5-3.0 g, seaweed extract 50-100 g, sucrose 115-180 g g. The chlorophyll content, net photosynthetic rate, and root activity of peanut leaves treated with this regulator at the pod stage were significantly higher than those of the controls, and the SOD activity and POD activity of the leaves were significantly higher than that of the controls, while the malondialdehyde content was significantly lower than that of the controls, indicating that Using this regulator can remove oxygen free radicals very well and delay aging; this regulator can significantly improve the activity of leaf nitrate reductase, glutamine synthetase and glutamic acid synthase, and increase the activity of leaf sucrose synthase and sucrose synthase. Phosphate synthase activity is beneficial to the accumulation of dry matter in pods and the synthesis of protein and fat in seeds. Significantly increased the yield of peanut pods. The reason for the increased yield is that the weight of a single fruit was significantly increased, the rate of full fruit was increased, and the rate of double-seed fruit and the rate of kernels were greatly increased.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut pod setting stage. Background technique [0002] 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 control excessive gr...
