Problems solved by technology

In the prior art, active ingredients in Lycoris and Pyrethrum are used to control insects and kill insects. For example, in the document "Suggestions on the Development, Utilization and Breeding of Lycoris Resources", it is pointed out that lycorine and the like are more toxic, and it is extracted Make high-efficiency insecticidal, low-concentration biopesticides for bactericidal; "Cultivation Technology of Biopesticide Raw Material Pyrethrum" mentioned that pyrethrum mainly contains pyrethrum and pyrethrin, and flowers, stems and leaves can be used to make pyrethrin pesticides, which are synthetic enemy It is an important raw material for killing, quick killing and making mosquito-repellent incense, mosquito repellent oil, and lice powder. However, in the prior art, there are few reports on the technology of planting insecticidal plants for biological control

Embodiment 1

[0018] Trials began on April 10, 2012. Source of pyrethrum seeds: online purchase, merchant Leshan City, Sichuan, Leshan Zhongtian Yitai Trading Co., Ltd. Lycoris bulb source: Yangchang Base, Wudang District, Guiyang City. The test site was set up in the rice planting area of ​​Yangchang Town, Wudang District. The rice planting area was planted with one season of rice, and the rice was sown on April 10, using the direct seeding method. On April 10, 2012, the pyrethrum seeds were soaked and accelerated germination according to claim 3. On April 14, 2012, a row of Lycoris, Plant a row of pyrethrum, make a ridge in the middle of the rice field, and plant amaryllis and pyrethrum in the same way. Every time rice is topdressed, apply appropriate amount of fertilizer to amaryllis and pyrethrum. The survey of diseases and insect pests was carried out in the next year after planting, that is, on June 15, July 15, August 15, and September 15, 2013, at a place about 200 meters awa...

Embodiment 2

[0025] Trials began on April 10, 2012. Source of pyrethrum seeds: online purchase, merchant Leshan City, Sichuan, Leshan Zhongtian Yitai Trading Co., Ltd. Lycoris bulb source: Baiyi Base, Wudang District, Guiyang City. The test site is located in an orchard near Baiyi Base in Wudang District, where pear trees are planted. On April 10, 2012, the pyrethrum seeds were soaked and accelerated germination according to claim 3, and on April 14, 2012, one mu of orchard was planted according to claim 1. The survey of diseases and insect pests was carried out in the next year after planting, that is, on April 15, June 15, August 15, and October 15, 2013, at a place about 200 meters away from the field where Lycoris and pyrethrum were cultivated, Another two one-acre orchards were divided at the same latitude as controls (one acre of which was not applied with pesticides, and one of which was applied with conventional pesticides). During the investigation, 5 points were taken from...

Abstract

The invention relates to a method for biologically preventing and controlling crop diseases and insect pests, in particular to a method for interplanting lycoris and pyrethrum to prevent and control crop disease and insect pests. The method includes planting the lycoris and the pyrethrum on the peripheries of crop cultivation lands in a matched manner to achieve purposes of preventing and controlling the crop diseases and insect pests. The method has the advantages that ecological environments of the cultivation lands can be improved, the crop diseases and insect pests can be controlled for the cultivation lands without chemical pesticides, accordingly, the amounts of pesticides applied to main crops of the cultivation lands can be greatly reduced, pesticide residues of the crops can be guaranteed against exceeding standards, and the organic crops can be manufactured; the lands can be sufficiently utilized, so that the environment can be beautified.

Description

technical field [0001] The invention belongs to the technical field of biological prevention and control of crop diseases and insect pests, and relates to a method for a biological prevention and control system of plant diseases and insect pests using plant allelopathy. Background technique [0002] At present, pests and diseases are an important reason affecting the yield and quality of crops. Although the commonly used chemical control methods are effective, they have brought a greater impact on the environment, causing serious problems such as excessive pesticide residues, quality decline, and environmental and groundwater pollution. , Long-term use of certain pesticides will cause pests to develop resistance, and the dosage must be increased. The dosage is getting bigger and bigger, the effect is getting worse, and the environmental pollution is getting worse. With the improvement of people's living standards, the requirements for crop quality and ecological environment ...
