Since 2017, the Beijing Plant Protection Station has carried out research on the occurrence, damage characteristics and prevention and control techniques of pests and weeds against newly introduced crops, and has achieved some stage results. The successful introduction of food source trapping technology has been applied to the prevention and control of fresh corn borer pests, which has achieved remarkable results and provided a scientific basis for large-scale promotion and application. Due to the high sweetness of fresh corn, the ear is susceptible to foraging pests such as cotton bollworm, corn borer, and peach aphid. At this time, the corn plant is high, the field is muddy, and chemical control is relatively labor-intensive, so planting The households rarely carry out the control of pests, which results in a decrease in the commodity rate of the ear and a decline in the income of the farmers. In order to solve this practical problem of production, the station carried out a bio-feeding technology test. The experiment was arranged in the southwest block of Xiapudian Village, Doudian Town, Fangshan District. The test results are three: First, the bio-feeding agent can be used to control the drill-bit pests in the fresh corn field, and the three medicines can obviously enhance the fresh corn ear. Commodity rate, the average ear commodity rate increased by 5.7% compared with the control, and the average yield per mu increased by 6.5%. Second, the bio-feeding agent can not only trap the borer moth pests but also trap the fruit fly, flies and beetle pests, which can reduce the ear and improve the farmland environment. Third, the use of bio-feeding agents in fresh corn fields can increase the average income by 98.8 yuan per mu, and increase the safety of ear food consumption. Therefore, it can be promoted and applied in fresh corn fields. Basically, the biological characteristics, spawning characteristics and wintering insects of the buckwheat beet tube in Beijing were found out, and a set of scientific green prevention and control technology was proposed, which effectively played a role in ensuring the production of buckwheat in the city. The sugar beet tube is a newly discovered pest of buckwheat in Beijing, which has an area of ​​200 mu. In order to control its harm, a prevention and treatment method was proposed: First, plant quarantine. Strengthen the inspection and quarantine work of the carp, carp and carp family, including buckwheat and edible and ornamental beet, leeks and other seedlings, and strictly prevent the introduction of beet pulp and its further spread. The second is seed coating. Coating the buckwheat seeds with high-efficiency suspension coating agent 2.4g/kg + rickett suspension coating agent 0.5g/kg can effectively reduce the damage of the beet tube stalk adult and stem rot to the buckwheat seedling stage. The third is to clean the countryside. The eradication and complete destruction of weeds at the edge of the field in the fall can significantly reduce the number of insects in the beet. The fourth is chemical control. For adults, it can be sprayed with high-efficiency and low-toxic agents that are both venom and stomach poison. The selected agents are flubendiamide, Kangkuan and beta-cypermethrin, and attention should be paid to rotation. The fifth is biological control. The species of the genus Ignida have a good control effect on the larvae of the beet colony, and the parasitic rate in the field can reach 50%, which can be introduced and evaluated. The research on chemical weeding test of millet field was carried out, which provided a basis for large-scale promotion and application. The occurrence of cereal weeds is widespread and varied, which greatly affects the development of millet. At present, there are few herbicides widely applied in the field of grain in Beijing, and the traditional artificial alfalfa has a large workload, increased costs and reduced benefits. Therefore, it is of great significance to study the application of herbicides in millet production. The 10% monosulfuron-methyl WP was applied to the field plotting of Yugu 18 in the field. The results showed that 10% monosulfuron-methyl WP was treated at the seedling stage of millet seedlings. The production used 1.8 kg per hectare, safe for millet, 15 after drug The day's defense effect was 91.9%, and the community increased production by 44.8%. It provides a theoretical basis for large-scale application in production. Disclaimer: Some articles on this website are transferred from the Internet.
