Description

A fertilization device and a fertilization method for agricultural planting

Technical Field

The present invention relates to the technical field of agricultural planting and fertilization, and in particular to a fertilization device and a fertilization method for agricultural planting.

Background technique

Fertilization of crops includes solid fertilizer fertilization and liquid fertilizer fertilization. Solid fertilizer is mostly suitable for outdoor fields. The fertilization process of solid fertilizer is relatively complicated and requires soil covering, so the fertilization efficiency is relatively low. Liquid fertilizer is widely used in agricultural planting due to its advantages such as convenient fertilization and good absorption effect of crops. The fertilization process of liquid fertilizer is generally carried out by manual spraying or by drone spraying. The manual spraying method is relatively inefficient, the spraying uniformity is relatively poor, and the labor intensity is high. The price of drone spraying is relatively high, and the use environment of drones is limited, and they cannot be used in indoor environments such as greenhouses.

Most of the existing fertilization devices used inside greenhouses are to set a spray pipe on the top of the greenhouse, set a spray head on the spray pipe, and spray the crops through the spray head. Although this method of fertilization reduces labor and provides convenience, the spray head is fixed. On the one hand, it is necessary to lay more pipes in the greenhouse. On the other hand, the fixed spraying position leads to uneven spraying. In addition, since the absorption of crops requires a process, the fixed spraying position is not conducive to the absorption of nutrients in the fertilizer by the crops, affecting the fertilization effect. The current spraying fertilization is generally sprayed above the crops. Due to the obstruction of the branches and leaves of the crops, the roots of the crops cannot be effectively fertilized, which also affects the effect of fertilization.
