Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fertilizing equipment, and particularly relates to a single-row powdery solid-state fertilizer applicator. BACKGROUND

[0002] Solid-state fertilizer is a common type of fertilizer in agricultural production, which includes various organic and inorganic fertilizers, such as compost, farmyard manure, compound fertilizer, etc. The solid-state fertilizer application technology mainly involves the design of fertilizing machinery, the optimization of fertilizing methods, and the selection of fertilizing timing, etc. With the development of agricultural mechanization, the design of solid-state fertilizer application machinery is becoming more and more mature.

[0003] The existing solid-state fertilizer applicator either directly buries the solid-state fertilizer into the soil or collects the soil in the ditch, mixes the soil with the solid-state fertilizer, and then backfills it into the ditch. Directly burying the solid-state fertilizer into the soil will cause the solid-state fertilizer to be more aggregated and unable to be uniformly released into the soil. The method of mixing the soil with the solid-state fertilizer and then backfilling it will cause part of the solid-state fertilizer to be located on the surface of the soil and be directly irradiated by sunlight. The ultraviolet rays and high temperature in the sunlight will accelerate the volatilization and decomposition of some components in the solid-state fertilizer, resulting in reduced fertilizer efficiency. SUMMARY

[0004] In view of the above problems, the present application aims to provide a single-row powdery solid-state fertilizer applicator which can mix the soil with the solid-state fertilizer and then backfill it into the ditch, and also can cover a layer of soil with adjusted humidity on the backfilled soil, so that the solid-state fertilizer is uniformly distributed, the volatilization of components caused by direct irradiation of sunlight is avoided, and the soil can be preserved.
