Device for preventing rice seedlings from being stiff and using method thereof

Abstract

The invention belongs to the technical field of agriculture, in particular to a device for preventing rice seedlings from being stiff and a using method thereof. The device comprises a sliding grooveframe, wherein a No.1 baffle plate and a No.2 baffle plate are respectively arranged at two ends of the sliding groove frame; a motor is arranged on one side of the No.2 baffle plate; a control box isarranged on the upper side of the motor; a pesticide spraying box is arranged on the upper side of the sliding groove frame; and a fixing groove is formed in the top of the sliding groove frame to facilitate fixing the pesticide spraying box. A PLC can be used to control the sliding groove frame, a water gun spraying port, a metering device and three valves to automatically weigh and inject feedsand spray pesticides, so that the device is simple and convenient; by arranging a plurality of dense holes, the pesticides can be sprayed evenly, when the rice seedlings are stiff due to phosphorus deficiency, a phosphate fertilizer is added and applied skillfully, 30-50kg of phosphate fertilizers are used as surface fertilizers per mu or 50kg of limes are used as base fertilizers per mu; and when the rice seedlings are stiff due to potassium deficiency, the physical and chemical properties of soil are improved, the potassium supply capacity of the soil is improved, a potash fertilizer is added, generally, about 20kg of the potash fertilizers are added per mu. The affected fields are drained immediately, so as to restore the growth of rice plants as soon as possible.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a device for preventing and treating stiff rice seedlings and an application method. Background technique [0002] Rice (Oryza L.) is a cereal crop of the Poaceae family, and it is the most important food crop in China. The representative species is rice (scientific name: Oryza sativa L.). Annual herb; leaves long, flat; spikelets compressed laterally, with 3 florets, arranged in panicles; glume degenerated, only at the tip of spikelet peduncle in two half-moon shape; lemma of sterile flowers is very small, bearing flowers The lemma is hard, with 5 veins, and the outer veins are close to the edge of the scroll, sometimes with awns; the inner palea is similar to the lemma, but the back has no central rib; the stamens are 6. [0003] Rice is one of the most important food crops in Southeast Asia. Its strains can be divided into two categories: upland rice and pa...
