Description

Liquid fertilizer applicator for forestry cultivation and method thereof Technical Field The invention relates to the technical field of fertilizer applicators, in particular to a liquid fertilizer applicator for forestry cultivation and a method thereof. Background In the process of forestry cultivation, scientific fertilization is an important measure for guaranteeing healthy growth of seedlings and improving survival rate and yield of trees. The liquid fertilizer is widely applied to modern forestry production due to the advantages of uniform nutrients, easy absorption, convenient application and the like. However, the conventional liquid fertilizer application device still has a plurality of technical bottlenecks in practical application, and particularly, the problem is more prominent in complex working environments such as forest areas, nursery or mountain areas without power supply. Firstly, the traditional liquid fertilizer distributor relies on an external electric power or hydraulic system to drive a stirring device so as to prevent suspended particles (such as microelements, organic matters and the like) in the liquid fertilizer from precipitating, thereby ensuring the uniformity of the fertilizer concentration. However, in forestry operation scenes far away from a power grid and lacking a matched power source, the equipment is difficult to effectively operate, so that the fertilizer is unevenly mixed, the fertilizer application effect is affected, and even partial seedling burning or insufficient nutrition is caused. Secondly, the existing fertilizing equipment generally adopts a fixed spraying structure, so that surface spraying can be realized only, and the fertilizing depth can not be flexibly adjusted according to different growth stages of the nursery stock (such as shallow root system in the initial stage of seedling culture and deep root system in the middle stage of seedling culture). This not only causes a large amount of fertilizer to stay on the soil surface layer, is easily lost by rain wash or sun volatilization, but also reduces the fertilizer utilization rate, increases the cost, and is unfavorable for the effective absorption of nutrients by the root system, therefore, a liquid fertilizer for forestry cultivation and a method thereof are needed to solve the above problems. Disclosure of Invention The invention aims to provide a liquid fertilizer applicator for forestry cultivation and a method thereof, which have the advantages of no need of an external power supply, automatic stirring, stable pressure, adjustable fertilization depth and integrated ditching and backfilling, and solve the problems of uneven stirring, single fertilization mode and uncontrollable depth of the existing equipment in a non-electric environment.
