Abstract
The invention discloses a planting method, which is characterized in that different varieties of tea trees are intercropped, and the different varieties of tea trees have differences in pest resistance so as to reduce the harm of pests to the tea trees with weak pest resistance. The invention adopts the same kind of plants for intercropping, which is convenient for agricultural management. The planting method can reduce the using amount of pesticides, improve the ecological environment, control the harm of pests to insect-resistant weak tea trees, improve the yield of tea, and is beneficial to the improvement of the living standard of farmers and the sustainable development of agriculture.
Description
Technical Field
The invention relates to the technical field of agricultural planting, in particular to a planting method capable of reducing insect pests.
Background
The agricultural diseases and insect pests are ubiquitous in agricultural production, the agricultural diseases and insect pests can greatly influence agricultural production activities, the agricultural diseases and insect pests directly influence the production quantity of agricultural products, and great loss can be brought to agricultural growers.
Tea is a traditional export agricultural product in China, and along with the development of society and the progress of science and technology, people put forward higher and higher requirements on the quality of tea, so that the tea is required to be good in color, aroma and taste, and is required to be sanitary and safe. Therefore, tea production must adapt to the change of market demands, pollution-free, ecological, environment-friendly and healthy pollution-free tea leaves are vigorously developed, and the sustainable development of tea leaves is realized. For years, the prevention and the treatment mainly depend on chemical pesticides, so that the serious drug resistance of pests such as leafhoppers and the like is caused, the pesticide residue of tea leaves is often over-standard, a large number of natural enemies are killed, a food chain and a food net are simplified, and the natural control potential is weakened. The prohibition of using any chemical pesticide in the production of organic tea, pest control and the like become the biggest obstacles in the development and industrialization process of organic tea. The prevention and control modes of biological pesticide, natural enemy release and the like have certain limitations. Aiming at the problem that pollution-free prevention and control of main pests such as leafhoppers and the like become bottleneck problems of tea industry development, a new green, cyclic and low-carbon pest and disease control way is required to be found.
Intercropping and interplanting are one of the essentials of the traditional agriculture in China, and various modes of intercropping of forest trees, fruit trees and tea trees are established in long-term production practice. The current tea garden intercropping utilizes the characteristics that tea trees are wet-loving and shade-tolerant, plants are shrubs or small trees, the root systems are shallow and the like, plants with different heights and the depths of the root systems are reasonably selected to form a tea garden ecological system with two layers of canopy and tegument, the species are emphasized to be harmoniously developed, the mutual promotion is realized, the land capability is fully utilized, and the maximum economic benefit and the better ecological benefit are obtained.
The method is characterized in that the method comprises the following steps of surveying the occurrence number of main plant diseases and insect pests and natural enemies of tea trees in 2 growth periods of spring tea and autumn tea in 3 intercropping modes of camphor-tea, wild pepper-tea and agilawood-tea. The results show that: the camphor, wild pepper and agilawood planted in the middle of the tea garden have inconsistent influence on main plant diseases and insect pests and natural enemies of the tea garden. The incidence of tea leaf spot and tea brown spot of the camphor intercropping tea garden is lower than that of a control tea garden, but the incidence of tea leafhoppers is increased; the incidence of the diseases of the tea cake in the wild pepper intercropping tea garden and the insect pests of tea lesser leafhoppers are lower than those in a control tea garden; the quantity of tea lesser leafhoppers, tea thrips and tea aphids in the agilawood intercropping tea garden is reduced compared with that in a control tea garden, and the incidence of tea wheel spot and tea coal disease is also reduced compared with that in the control tea garden (Sun Yunnan, ran 29667, Chuai, et al. investigation and research on main plant diseases and insect pests and natural enemies in tea gardens of different intercropping modes [ J ] Shandong agricultural science, 2014(11): 110-.
The influence of different green fertilizers on the empoasca vitis and the natural enemy thysanoptera in tea garden intercropping of tea gardens is researched in the tea and ocean organic tea base of the engineering meaningful Yongtian tea industry company. The results show that the difference of the population of the empoasca vitis in the tea garden treated by different intercropping treatments is obvious (F is 3.15, P is less than 0.05), and the difference of the population of the empoasca virgifera is extremely obvious (F is 4.22, P is less than 0.01). Intercropping and paving a woodblue and rhodon bean tea garden, wherein the maximum number of insect population of the empoasca vitis is 1035, the minimum number of insect population of the intercropping and paving a woodblue and rhone bean tea garden and the minimum number of insect population of the empoasca vitis is 378; the quantity of the insect population of the natural enemy tassel wasps of the leafhopper is 263 th maximum in the intercropping white clover and round-leaf cassia tora tea garden, the quantity of the insect population of the tassel wasps is improved by 61.98 percent compared with that of the insect population of the blank control, and the population quantity of the natural enemy tassel wasps is obviously improved by intercropping green manure in the tea garden. Different intercropping treatment tea garden empoasca vitis is in obvious positive correlation with natural enemy Thysanola. Intercropping white clover and round-leaf cassia seed, the average benefit-to-pest ratio in the tea garden is 0.56 at most, and the average benefit-to-pest ratio in the control tea garden is 0.18 at least (Li Hui Ling, bolt, Guo Jianxiong, et al. the influence of intercropping green manure in the tea garden on the empoasca vitis and the natural enemy tassel wasp [ J ]. Chinese biological control proceedings, 2016,32(1): 50-54.).
The Zhangzheng group and the like research the influence of the Zhang zheng group and the like on the quantity of tea garden pests and natural enemy population, soil nutrient condition, tea plant growth, tea leaf biochemical components and the like through tea garden intercropping aromatic plants, and analyze the ecological comprehensive regulation and control effect of the intercropping aromatic plants on young tea gardens. The aromatic plants are planted among young tea gardens, so that the number of the smaller-leaf green leafhoppers and the green plant bugs can be reduced, and the number of natural enemies such as ladybug, lacewing, parasitic wasps, spiders and the like in the tea gardens can be increased; the contents of ammonium nitrogen, available phosphorus and available potassium in the soil of the aromatic plant intercropping area are higher than those of the green manure intercropping area and the control; the intercropping of aromatic plants in the tea garden can promote the growth of tea trees to a certain extent, cultivate the tree vigor and crown of young tea gardens and increase the yield of tea leaves. The aromatic plant intercropping in the tea garden can reduce the content of tea polyphenol and caffeine in the tea, improve the content of soluble sugar and catechin and improve the quality of the tea. It can be seen that the tea garden intercropping of aromatic plants is a tea garden cultivation management mode with better ecological benefits, and can promote the development of the ecological tea garden (Zhang Zheng Tu, Tianyue, Gao Shun, et al. research on the influence of the intercropping of aromatic plants, basil and perilla frutescens in the tea garden on the ecological system of the tea garden [ J ] tea science, 2016,36(4): 389-.
