Pest prevention and growth promotion method for nectarines

Abstract

The invention relates to the field of agriculture, in particular to a pest prevention and growth promotion method for nectarines. According to the method, a natural pesticide obtained by extracting radix rhapontied, mexican tea herbs, herba agrimoniae and artemisia argyi is sprayed onto whole nectarine plants to achieve the effect of fully killing pests of the nectarines; diesel or silicone oil can also be added so that the pesticide can permeate into the bodies of coccids, and the effect of killing the coccids on the surfaces of branches is achieved; a branch leaf protection agent obtained bymixing and extracting herbs of artemisia annua L., radix rubiae, flos inulae, japanese buttercup herbs, caraway seeds and flos chrysanthemi is brushed on branches, leaf surfaces and fruits of the nectarines, so that the bare branches of the nectarines are completely covered, the food refusal effect on the pests is achieved, the population formation of the pests is inhibited, and the effect of attracting natural enemies of the pests is achieved; radix euphorbiae lantu and winter cherry are applied into soil of a nectarine planting area, and larvae and eggs of underground pests and various pests in the soil are fully killed. The pest prevention and growth promotion method for the nectarines can effectively improve the pest resistance of the nectarines, kill the nectarine pests and reduce the incidence rate of the nectarine pests and does not require the use of chemical pesticides.

Description

technical field [0001] The invention belongs to the field of agriculture, in particular to a method for preventing insects and promoting growth of nectarines. Background technique [0002] Nectarine (Latin name: Prunus persica var. nectarina), also known as peach rebuttal plum. Nectarine (English: Nectarine) is a variant of common peach (the skin is covered with hairs). It is a small deciduous tree with fruit as a fruit. Nectarine originated in China and is distributed in Asia and North America. [0003] Nectarine is rich in nutrition, containing 13% sugar, 1.5% organic acid, 1% pectin and 1.1% protein, and every 100 grams of pulp contains 12 mg of Vc, 40 mg of phosphorus, 12 mg of calcium, 0.8 mg of iron, and 14.5 mg of magnesium; in addition, it also contains 17 kinds of The amino acids and carotene needed by the human body have the functions of relieving cough and reducing phlegm, invigorating qi and strengthening kidney, and lowering blood pressure.

Problems solved by technology

[0004] At present, the pests that harm nectarines mainly include: green peach aphid, borer, scale insect, etc. In order to prevent pests, chemical pesticides are often used in large quantities during the planting of nectarines. Extensive and unreasonable application of chemical pesticides will have a negative impact on the ecological environment. Pollution and destruction are caused, and a large number of beneficial insects are also poisoned, which leads to the occurrence of insect pests more easily and more seriously in the second year. Serious harm, how to scientifically prevent and control insect pests and improve the quality of nectarines has become an urgent problem in the current nectarine process
