Description

Root pesticide applying device special for peanuts

Technical Field

The invention belongs to the technical field of pesticide application devices, and particularly relates to a root pesticide application device special for peanuts.

Background

The peanut root diseases are complex and troublesome, in particular to southern blight, root rot, stem rot and the like. The southern blight of the peanut is a soil-borne sclerotinia rot, pathogenic bacteria are sclerotinia rolfsii, and the pathogenic bacteria are distributed in surface soil of 1-2 cm. After the roots, the pods and the bases of the peanut plants are damaged, the peanut plants are initially brown and soft-rotted, white silk-like hyphae (so called southern blight) are formed at the roots and the roots of the overground part, the white silk is usually formed at the bases of the stems close to the ground and on the soil surface close to the bases, the diseased parts are gradually dark brown and glossy, and the bases of the plant stems are girdled by scabs and die. The root rot of the peanut can be caused in the whole growth period, the root of the peanut is rotten, no lateral root or few lateral roots exist after the peanut is pulled out, and the root is in a rat tail shape. The seedlings are damaged, the main roots are browned, the infected plants are short, and the leaves are sequentially yellowed and withered from bottom to top. The symptoms in the adult stage cause slightly depressed brown spots at the roots, and the overground part gradually wilts and dies. The disease is easily caused by rainwater and field farming operation activity propagation, field water accumulation in seedling stage, low ground temperature or early and deep sowing. The peanut stem rot pathogen invades plants from cotyledons or radicles, generates yellow-brown water stain-like disease spots at root necks, and then turns black brown to cause the root tissues to rot. When the environment is wet, conidiophores (namely small black bulges) are generated at the diseased part, the epidermis of the diseased part is easy to peel off, and fibrous tissues are exposed. When the environment is dry, the epidermis of a diseased part is sunken and is tightly attached to the stem, after the disease is infected in the adult stage, the whole plant withers in about 10-30 days, the diseased part is mostly attached to the ground at the stem base part, and the phenomena of staged withering of the main stem and the lateral branches sometimes occur. The harm of the peanut root diseases is great, firstly, peanut plants change colors and wilt, so that root tissues are rotten, and finally, the plants die. The prevention and treatment effect is poor after the diseases such as southern blight, root rot and stem rot occur, so that the root application prevention and treatment are carried out as soon as possible, and the diseases are avoided.

The existing root pesticide applying device is generally used for punching and injecting pesticide, the pesticide applying pipe is directly inserted into the ground for spraying, so that the problem of blocking the pesticide applying pipe is easy to occur in the underground inserting process, and the root tissues are easy to be damaged, therefore, the pesticide is often applied above a plant when the root part of a flower is applied, the pesticide is applied above the plant to ensure that the pesticide is difficult to be sprayed onto the root tissues of the plant, the pesticide applying pipe is required to manually extend into the peanut plant for pesticide application, or the peanut plant is manually pulled to apply pesticide to the root tissues, the pesticide applying time is prolonged, and the pesticide applying effect is not ideal.
