Fertilizer applicator and fertilizer suitable for being used by fertilizer applicator

Abstract

The invention relates to a fertilizer applicator and a fertilizer suitable for being used by the fertilizer applicator. The fertilizer applicator (1) can be divided into a fertilizer water flow guide pipe (1a), a fertilizer cavity (1b) and a cover (1c) from one end inserted into the soil; the fertilizer water flow guide pipe (1a) is a hollow pipe; the lower end (1a1) of the pipe (1a) is provided a through hole (1a1a); the upper end (1a2) of the pipe (1a) is connected and communicated with the fertilizer cavity (1b); a material (1d) capable of absorbing water and guiding water is contained in the fertilizer water flow guide pipe (1a); a structure (1e) capable of being used for regulating the fertilizer water flow guide quantity and a soil EC meter (1f) are also arranged on the fertilizer applicator. The fertilizer applicator has the advantages that the controllability on the fertilizer release speed to a certain degree is realized; the speed is adjustable according to the requirements; the slow release effect on the fertilizer is high; the continuous fertilizer supply to the plants can be realized; the fertilizer application labors can be reduced; various kinds of fertilizer damage due to improper fertilizer application can be effectively avoided; the fertilizer loss can be obviously reduced; the structure of the fertilizer applicator is simple; the use is convenient; no pollution is caused; the cost is low.

Description

technical field [0001] The patent belongs to the technical field of agriculture and horticultural cultivation and fertilization, in particular to the technical field of potted plant fertilization. Background technique [0002] A single flower in a crop depends entirely on fertilizer, which is an important factor in determining plant growth and yield. [0003] Since German chemist Liebig put forward the theory of plant mineral nutrition in 1840, the fertilizer industry has become a powerful force to promote the development of agriculture in the world. The famous American crop breeder and Nobel Prize winner Norman E. After various factors in production, it is believed that half of the increase in crop production worldwide is due to the use of chemical fertilizers. [0004] Although chemical fertilizers have played a huge role in agricultural production, they have also caused many problems. The biggest problem is that the utilization rate of chemical fertilizers is low after t...

AI Technical Summary

Problems solved by technology

Other problems of chemical fertilizer application include: excessive fertilization or improper fertilization can also easily cause fertilizer damage, such as: burning seedlings and reducing production, and the fertilization process requires a lot of labor, etc.

[0005] The inventor of this patent has also deeply realized various problems existing in the present potted plant fertilization in the practice of carrying out plant potted planting: if the applied fertilizer is too close to the plant during potted planting or if it is excessively applied, it is more likely to cause damage to the plant than in the field. Death; due to more frequent artificial watering during the potting process, fertilizer loss is faster, and sometimes heavy rain for several days can also leaching all the fertilizer just applied; frequent fertilization not only consumes a lot of labor, but also causes huge waste of fertilizer , but also have a negative impact on the environment

[0010] Application number: CN02262330.2 (a seeding and fertilizing machine), which combines fertilization with ditching, sowing, suppression, mulching and other agricultural machinery, which can greatly improve the efficiency of planting and fertilization, reduce labor input, and is suitable for large-scale planting. However, it does not solve the problems of fertilizer release rate, serious loss and low utilization rate.

[0011] Application number: CN00263852.5 (a cylindrical fertilizer deep applicator), which provides a simple solid fertilizer fertilization method and device, simple structure, easy to use, flexible, suitable for small-scale planting, can be used to a certain extent Increased fertilization efficiency, but issues of fertilizer release rate and high runoff and low utilization remain unresolved

[0012] Application number: CN201410587147.5 (a water and fertilizer integrated micro-spray irrigation and fertilization system), trying to integrate irrigation and fertilization, thereby reducing fertilization labor, etc., but this fertilization method requires special equipment and large investment , not flexible enough to use
