Problems solved by technology

So far, there has been relatively little research on the relationship between natural enemies, pests and habitats in tobacco fields, the impact of crops adjacent to farmland on the number of natural enemies and pests in tobacco fields, and the impact of chemical control on the population of natural enemies and pests. Whether it can completely rely on agroecological control Technology to multiply local natural enemies, so as to achieve the purpose of pest control, has not been reported so far

Embodiment 1

[0012] In the experiment, two treatments were set up: the control field and the flue-cured tobacco field planted with sunflower traps (hereinafter referred to as; trap fields), see figure 1 , the trapping field is to maintain the current cultivation method of flue-cured tobacco, the plant spacing, row spacing and density of flue-cured tobacco are the same as the conventional cultivation method, and the flue-cured tobacco field 1 is 667m 2 , the tobacco moisture 2 in the flue-cured tobacco field block 1 is the same as the conventional method, plant a row of flue-cured tobacco (flue-cured tobacco planting row 3) in each tobacco field block, plant a row of sunflowers 6 around the same flue-cured tobacco field block 4, and plant a row of sunflowers 6 in the flue-cured tobacco field block. Each piece of tobacco moisture 2 and two ends of tobacco moisture 5 each plant a sunflower 6. The sunflowers are sown 25 days before the flue-cured tobacco is transplanted. The plant spacing H is...

Abstract

The invention discloses a method for protecting natural enemy insects by planting a sunflower luring belt in a tobacco field and belongs to the technical field of plant protection. The method maintains the existing tobacco cultivation mode, a line of sunflowers are planted in the periphery of the same tobacco field per 667 m<2>, a sunflower is planted in each end of each tobacco moisture block in the tobacco field, and the sunflowers are planted 25 days before the tobacco is transplanted. By means of the method, a luring and protection effect of the sunflowers on the natural enemy insects of the tobacco is effectively achieved, habitat adjustment is conducted, a habitat island in a tobacco filed ecological system is built and protected, an ecological environment favorable for proliferation of the natural enemy insects of tobacco is created, the total number of the natural enemy insects is increased by 30.35%, diversity index and evenness index of the natural enemy community are both increased, dominant concentration index is reduced, myzus persicae average plant damaging rate is reduced by 36%, damage conducted by injurious insects is effectively controlled, and a natural control effect of natural enemies on the injurious insects is promoted.

Description

technical field [0001] The invention relates to a method for planting sunflowers in flue-cured tobacco fields to protect natural enemy insects, and belongs to the technical field of plant protection. Background technique [0002] Due to the use of a large number of chemical pesticides, pests develop resistance, and a large number of natural enemies are killed, causing pests to flourish again. Ecological damage and environmental pollution have become the main obstacles to agricultural production. Using ecological principles to restore ecological balance and virtuous circle and promote the development of agricultural production is an important task at present. The protection and utilization of natural enemy insects is an integral part of integrated pest management, which can greatly reduce the use of chemical pesticides. It has become one of the basic measures of integrated pest management in my country and has important ecological significance. Use plants that attract and sh...
