Small-sized rice liquid fertilizer deep applicator

Abstract

The invention relates to a small-sized rice liquid fertilizer deep applicator. A charging basket is arranged above a frame of the fertilizer deep applicator; support legs are arranged below the frame; the lower end of each support leg is connected with a carriage which is provided with a slot; the slot is movably provided with a copying opener which is provided with a fertilizer applying channel; the outlet of the fertilizer applying channel is formed on the rear lower part of the copying opener; after the copying opener is cut in the soil, fertilizer solution is applied to the deep part of the soil through a fertilizer delivery pipe and the fertilizer applying channel; and the fertilizer solution is sealed in the field soil by a soil sealing block so as to supply nutrients to rice. The fertilizer deep applicator can effectively avoid the wastage of the fertilizer caused by field water overflow due to rain, or artificial drainage when the fertilizer is directly spread in field water, so that the effects of improving fertilizer efficiency, reducing area source pollution and increasing both production and income are achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a small rice liquid deep fertilizer applicator. Background technique [0002] Rice is one of the main grain crops in my country, accounting for about 1 / 2 of the country's total grain output. Rice is a crop that needs more fertilizers, and rational fertilization of rice is an indispensable and important link in agricultural production. At present, in the process of agricultural production, most of the fertilizers are fertilized by artificial throwing, that is, the fertilizers are directly sprinkled on the water in the field. The disadvantage of this method of fertilization is that the fertilizer is dissolved in water and is far away from the rice root, so it cannot be well absorbed by the rice root system, and the fertilizer utilization rate is less than 30%. , fertilizers will also be discharged along with the field water, resulting in waste of fertilizers and easy to caus...
