Description
Technical Field
The invention belongs to the field of fruit tree research, and relates to a pear germplasm anti-gall midge identification method, which can effectively solve the problem of rapid identification of pear variety anti-gall midge in pear scientific research, breeding and production. The method is suitable for scientific research units, companies and individuals engaged in pear scientific research, breeding and production.
Background
The pear belongs to the Rosaceae (Rosaceae) Maloideae (Maloideae) pear (Pyrus) plant, is a tree with tree leaves and fallen leaves, is one of three cultivated fruit trees in China, and plays a very important role in the world. According to statistics of agricultural rural departments in the people's republic of China, the pear planting area of 2016 years in China is 1113 kilohectares, the yield is 1870.44 ten thousand tons, and the pear is the first place in the world. Pear production is always an important post industry for increasing income and leading to wealth of farmers in China and is also one of main agricultural products for earning foreign exchange in exports of China. Along with the continuous expansion of the planting area of pears, various pest and disease damages of the pears are getting more and more serious day by day, and the pest and disease damages of the pears are getting more and more rampant day by day in recent years, and become the main pests of the pears.
Pear gall midge mainly takes larvae as flower buds, young tips and young leaves of a damaged pear tree, nail holes for adult pear gall midge to lay eggs are formed outside damaged flower buds, eggs are hatched into larvae in the flower buds, the larvae damage stamens and pistils, and after the flower buds are damaged, the interior of the flower buds become black, so that normal pollination and fruit setting cannot be realized; the pear gall midge harms the young leaves of the pears after blossom withering, the juice is absorbed at the leaf edge on the front side, the leaves are shriveled and deformed, become tumor-shaped and crisp, and are longitudinally and inwards rolled into a tight tube shape, and the pear gall midge larvae can be stripped in the damaged rolled leaves. The damaged leaves are curled into a cylinder shape, the leaf surfaces are uneven, the leaves are browned, dried and fallen off, bald branches are left, and the growth, development and yield of the tree body are seriously influenced. The spring tip, summer tip and autumn tip can be damaged. After buds, young leaves and young tips are damaged by pear gall midge, a large amount of flowers, fruits and leaves are easy to fall in the early stage, and the yield and the quality of pear trees are seriously influenced. After a part of the pear gardens are damaged, healthy branches and tips cannot be taken out all the year round, and the high yield performance of the pear trees is seriously weakened. Because the insect is damaged in the leaf curl, common insecticides are difficult to touch and kill the insect, the control difficulty is very high, the insect is one of the problems to be solved urgently in managing the pear orchard, and the damage of the pear gall midge seriously threatens the development of the pear industry. The existing method for preventing and controlling pear gall midge is to use chemical agents such as 22.4 percent of spirotetramat suspending agent, 10 percent of imidacloprid, 40 percent of chlorpyrifos, 1.8 percent of abamectin and the like. If the chemical agents are used for a long time, the problems of drug resistance of pests to the chemical agents, environmental pollution, harm to human health and the like are inevitably caused if the chemical agents are not used properly. In order to overcome the defects of drug resistance of chemical agents and reduction of chemical pesticide pollution, a reasonable and effective comprehensive control measure of pear gall midge is imperative. Screening of Chinese pear varieties with strong pear gall midge resistance is the most effective method for preventing and treating pear gall midge, but how to quickly and accurately identify the characteristic that pear varieties have pear gall midge resistance in the large-area popularization process is a major problem which needs to be solved in the front of scientific research and production personnel.
For years, based on the national fruit tree germplasm resource garden, a large number of scientific researches and tests are developed around the identification and evaluation of pear germplasm for resisting pear gall midges, and a set of pear germplasm anti-pear gall midge identification method is summarized and invented. The method is characterized in that when field pear gall midge larvae damage pear trees in the peak period, the new tip damage rate and the leaf damage rate of pear germplasm are investigated, the comprehensive damage rate of pear germplasm pear gall midge is calculated according to the new tip damage rate and the leaf damage rate of the pear germplasm, the pear germplasm pear gall midge-resistant identification standard is established, and pear variety pear gall midge-resistant identification evaluation is carried out on pear varieties.
