Embodiment 1

[0019] The method described in the present embodiment for realizing the method for reducing application of pesticides in citrus orchards may further comprise the steps:

[0020] (1) Citrus trees covered with silver and black two-color plastic film

[0021] From February to March of that year, the citrus tree tray soil was leveled, weeded and insect-proofed, and fertilized, and the orange orchard was covered with plastic film after fertilization; the film was a silver-black two-color reflective film (2 silk PE film, thickness 0.02mm), made of PE (polyethylene) material with strong flexibility, strong flexibility, not easy to tear, and can be recycled repeatedly; when the mulch is laid, ensure that the front of the silver-black two-color mulch is silver, the reverse is black;

[0022] According to the actual topography of the orangery, cover the entire border with film. When covering the film, stretch the film tightly and lay it close to the ground. Make sure that the silver si...

experiment example

[0035] The selected test site is located in an orchard in Heshan Village, Heshui Town, Yangchun City, Guangdong Province. The orchard covers an area of ​​60 mu, and the citrus variety is Gonggan.

[0036] Carry out citrus plantation according to the method in embodiment 1 in this orchard for two consecutive years in 2016-2017. Compared with the input and output of the orchard in 2015, the number of times of pesticide use has been reduced by 5-6 times, of which the number of times of herbicide use has been reduced by 2-3 times, which has greatly reduced the amount of pesticide use and the input cost of the orchard, reaching the level of pesticide use in citrus orchards. The purpose of reducing application and increasing efficiency, the specific efficiency data are shown in Table 1 below.

[0037] According to the current market price of pesticides and labor, the cost of pesticides and labor for each application in the citrus orchard is 150 yuan / mu, and the 60-mu orchard can red...

Abstract

The invention belongs to the technical field of integrated control of disease, insect and weed damages of plants and particularly relates to a method for realizing pesticide application reduction andsynergism of a citrus orchard. According to the method for realizing pesticide application reduction and synergism of the citrus orchard, silver black reflective films are used for covering citrus, and the stability of the planting conditions of the citrus can be better guaranteed; meanwhile, the number of pest population such as winged aphids, thrips and citrus psylla can be effectively reduced,and the use frequency of chemical insecticides can be thus reduced; in addition, germination and growth of weeds can be effectively inhibited, the annual use frequency of herbicides can be reduced by2-3 times and even the use of the herbicides can be completely eradicated in the whole citrus planting process, so that manual operation of intertillage, weeding, irrigation and the like can be greatly reduced, and the production cost can be reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of comprehensive prevention and control of plant diseases, insect pests and weeds, and in particular relates to a method for reducing pesticide application and increasing efficiency in citrus orchards. Background technique [0002] Citrus (Citrus reticulata Blanco) belongs to the Rutaceae plant, mostly distributed between 16°-37° north latitude, and is a tropical and subtropical evergreen fruit tree. Citrus likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. The growth and development, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil and wind, altitude, terrain and slope. [0003] China is one of the important origins of citrus, and it is also the largest producer of citrus. It is rich in citrus resources and has a variety of fine varieties. It ha...
