Spraying and applying method for preventing and controlling disease and insect of rice-wheat crop stem basement and spraying device thereby

Abstract

The invention discloses a spaying method for the disease and pest control of the stem base of rice and wheat crops and the spraying device of the spaying method. The method is characterized in that, a plurality of nozzles are arranged among the rows of crops or the ridges and are opposite to the stem base of the plants; spraying is carried out at both sides of the crops along the rows of crops or the ridges; the spraying device comprises a medical box equipped with a pump, a hose connected with the medical box, a handle connected with the hose and equipped with a switch and a rigid pipe connected with the handle; the nozzles are arranged at the end terminals of the rigid pipe; the rigid pipe is shaped like a fork by a main pipe and two pipe branches; the end terminals of the pipe branches are connected with a pair of nozzles by a tee. The spaying method for the disease and pest control of the stem base of rice and wheat crops and the spraying device of the spaying method have the advantages that, the control has a clear goal and the effect is intensified; pesticide stain area of the crops is reduced; pesticide is saved, and pesticide pollution is lowered.

Description

technical field [0001] The invention relates to a method for controlling crop diseases and insect pests by spraying medicine and a spraying device thereof. Background technique [0002] Rice sheath blight, rice planthopper, and wheat stem rust are pests and diseases that mainly harm the leaf sheaths and stem bases of plants. They can damage plant tissues, reduce plant transportation functions, and cause crop stems to rot and fall. even severely reduced production. In daily pest control, spraying devices are used to spray drugs on the top of crops. The spraying devices used are such as figure 1 Shown: there is a medicine box 1 with a pump 2 inside it, a hose 3 connected to the medicine box 1, a handle 4 with a switch on it connected to the hose 3, a straight rod-shaped hard tube 5 connected to the handle 4 , the shower nozzle 6 that is connected in hard pipe 5 ends. The prevention and control principle is to use atomized tiny drops of medicine to gradually settle down to a...
