Органик хүнсний үйлдвэрлэл нь орчин үеийн хөдөө аж ахуйн хөгжлийн чухал чиглэл юм. Органик газрын самрын тариалалтад утас хорхой (wireworm)-г хянах нь газрын самрын хортон шавьж, өвчин эмгэгийн удирдлагын тэргүүлэх зорилт болдог. Сүүлийн жилүүдэд манай хот органик газрын самрын тариалалтад төрөл бүрийн аргыг нэвтрүүлж, онцгой үр дүнд хүрч, органик газрын самрын чанарыг баталгаажуулсан...Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
I. Agricultural control measures:Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
1. Crop rotation. Implement a two-year, three-crop rotation of peanut--wheat, corn (soybean) to reduce the pest and disease base.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
2. Winter irrigation: Conduct winter irrigation after the autumn crop harvest; the greater the water volume, the higher the mortality rate of white grubs.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
3. Fertilization: Since white grubs can live in humus, self-made organic fertilizer must be thoroughly decomposed.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
4. Late sowing: In organic peanut production bases, the sowing period should be appropriately delayed (sowing may be carried out around May 1), so that more white grubs mature and move downward to pupate, thereby reducing damage.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
5. Manual collection: During peanut harvest and deep plowing in early spring, organize manual collection of white grubs to reduce insect density and lessen damage in the following year.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
II. Chemical control:Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
Before peanut sowing, in combination with seed dressing and fertilization, use 180 g of compound Beauveria bassiana per mu to control white grubs. The specific method of use is: 60 g for seed dressing, and 120 g mixed evenly with organic fertilizer during rotary tillage and spread into the field, resulting in excellent control efficacy.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/

1. Hang electronic insect-killing lamps: From early June to early September each year, hang variable-frequency electronic insect-killing lamps (40 mu/lamp), and turn on the lamps every evening to trap and kill adult insects.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
2. Unified prevention and control isolation belts: In organic cultivation, poplar and other trees are generally planted as isolation belts. After the wheat harvest, according to the habit of adult white grubs (scarab beetles) feeding at night on tall trees such as elm, poplar, and willow, spray the above tall trees uniformly with 40% omethoate emulsifiable concentrate at 1000 times dilution, or at a height of 1 meter on the trunks of elm and poplar trees, scrape off the old bark and apply 8-10 times diluted omethoate with a hemp brush. Because omethoate has systemic, stomach-poison, and contact-killing effects and a relatively long residual period, the control effect is good.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
3. Plant castor: Plant castor around the field to trap and kill adult scarab beetles, causing them to be anesthetized and then killed in a centralized manner.Өгүүлэл нь ...-аас авсанFOFCC-http://fofcc.org.cn/mn/11311/
