Precise quantitative fertilizer applicator of slow release fertilizer for use in saline and alkaline land soil improvement

Abstract

The invention provides a precise quantitative fertilizer applicator of a slow release fertilizer for use in saline and alkaline land soil improvement. The precise quantitative fertilizer applicator comprises a feeding rolling body, wherein the outer surface of the feeding rolling body is provided with a plurality of troughs; a shaft body for autorotation of the feeding rolling body is arranged in the feeding rolling body; the outer surface of the feeding rolling body is provided with a conveying belt which is attached to the feeding rolling body and can drive the feeding rolling body; the conveying belt is distributed within the angle range of 70-260 degrees on the feeding rolling body; a first follower roller is arranged on the feeding rolling body at the position of 70 degree; a second follower roller is arranged on the feeding rolling body at the position of 260 degree; a driving roller is also arranged on the left side of the feeding rolling body; the first follower roller, the second follower roller, the driving roller and the feeding rolling body are in wrapping connection by the conveying belt. The fertilizer applicator has the advantages that the fertilizer application amount is rationally set, the defect of residual fertilizer or poor soil improvement effect due to over mush fertilizer is avoided, the soil improvement period is short, the soil alkali return degree is low, the saline and alkaline land soil component can be controlled and the cultivated area of China can be improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a fertilization equipment, in particular to a precision quantitative fertilizer applicator for slow-release fertilizer used in saline-alkali soil improvement. Background technique [0002] Saline-alkali land, as the name suggests, contains a lot of salt in the soil, most of which are concentrated in coastal areas. According to different soil structures and different improvement time stages, there are different improved fertilizers. Many of these fertilizers are expensive. The inaccuracy of precise fertilization may cause waste of fertilizers, and even affect the overall plan for improving saline-alkali land. For example, using Scutellaria baicalensis to improve soil, there are strict requirements for watering and fertilizing Scutellaria baicalensis. How to quickly complete the improvement of saline-alkali land and how to realize quantitative fertilization is a direction worthy...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a precision quantitative fertilizer applicator for slow-release fertilizer in saline-alkali soil improvement, which can be used for soil improvement according to the growth of Scutellaria baicalensis and Soil composition, reasonable setting of fertilization dosage, fertilizer can perfect soil improvement, and will not cause fertilizer residue due to excess; or too little fertilizer, resulting in poor soil improvement effect, and the soil improvement cycle is greatly shortened, and the improved soil returns The alkalinity is low, which can well control the soil composition of saline-alkali land and increase the area of ​​cultivated land in my country
