Embodiment 1

[0018] The extract of Hypericum perforatum described in this example is obtained according to the method disclosed in Chinese patent CN100402543A, which specifically includes: after crushing the fruit of Hypericum perforatum into forsythia powder, the ratio of the weight of the forsythia powder to the volume of 90v / v% ethanol is 1 : 10 ratio, add 90v / v% ethanol solution to forsythia powder, at 70°C, reflux extraction for 6 hours, filter and collect filtrate and filter residue. Take the filter residue and carry out reflux extraction again in the same manner as above, filter and collect the filtrate and discard the filter residue, combine the filtrates collected twice, and concentrate in a vacuum to 1 / 10 of the volume of the original filtrate to obtain Hypericum perforatum extract.

Embodiment 2

[0020] According to the mass ratio of 1:1, hyperin and hypericin were mixed, and 12 g of the above mixture was dissolved in an ethanol solution with a volume concentration of 60% to obtain a solution with a mass concentration of 30 wt%. Another 100 g of fluorite crushed to the micron level was taken and completely immersed in the solution, mixed thoroughly and immersed until the ethanol volatilized completely. The impregnated fluorite is dried at a low temperature of 30-40° C. and ground to a particle size of less than 1 mm.

Embodiment 3

[0022] According to the mass ratio of 2:1, hyperin and hypericin were mixed, and 12 g of the above mixture was dissolved in an ethanol solution with a volume concentration of 60% to obtain a solution with a mass concentration of 30 wt%. Another 100 g of fluorite crushed to the micron level was taken and completely immersed in the solution, mixed thoroughly and immersed until the ethanol volatilized completely. The impregnated fluorite is dried at a low temperature of 30-40° C. and ground to a particle size of less than 1 mm.

Abstract

The invention belongs to the technical field of crop planting, and particularly relates to a method for preventing and controlling sweet potato underground pests based on plant extracts. According to the method for preventing and controlling the sweet potato underground pests based on the plant extract, the hyperforin perforatum extract is applied to planting soil before sweet potatoes are planted, and the sweet potatoes are prevented and controlled by utilizing the coordination effect of hyperoside and hypericin contained in the hyperforin perforatum extract; the compound has a good inhibition effect on underground pests-grubs in sweet potato planting soil, can effectively prevent and control the underground pests in sweet potato planting, and effectively ensures the yield and quality of sweet potatoes. According to the preparation capable of effectively preventing and controlling the sweet potato underground pests, the hyperforin perforatum extract or the mixture of hyperoside and hypericin is used for preventing and controlling grub pests for the first time, and safe and efficient planting of sweet potatoes can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a method for controlling sweet potato underground pests based on plant extracts. Background technique [0002] Sweet potato is an important crop product in my country. It has the advantages of super high yield and wide adaptability. As the bottom line crop of national food security and the energy crop with the greatest potential, sweet potato has been widely valued. my country is the world's largest producer of sweet potatoes. The moderate development of the sweet potato industry is in line with the central policy of storing grain on the ground, storing grain on technology, and agricultural transformation and upgrading, and is also conducive to ensuring national food security. As a pioneer crop of health food, sweet potato is the best food recommended by the World Health Organization, and fresh sweet potato is more and more popular. [0003] Grubs are a general...
