Description

TECHNICAL FIELD

[0001] The application relates to the field of plant cultivation, and in particular to an intelligent root layer infiltration irrigation and fertilization system. BACKGROUND

[0002] Plant cultivation needs to improve crop yield and quality through fertilization, and to protect soil health. The main purpose of plant fertilization is to increase crop yield, improve crop quality, cultivate soil fertility, and improve economic benefits. The basis for fertilization includes soil fertility level, crop type, target yield, climate environment, and fertilizer characteristics, so as to select appropriate fertilizers, estimate the required amount of fertilizers, and determine the fertilization time and fertilization mode. According to different fertilization times, fertilization can be divided into base fertilization and topdressing. According to different fertilization modes, fertilization can be divided into spreading, flushing, hole fertilization, and strip fertilization. Spreading and flushing are beneficial to the diffusion of nutrients and are convenient to apply, but the nutrient loss is large and the utilization rate is low. Hole fertilization and strip fertilization have less nutrient loss and high utilization rate, but consume a certain amount of mechanical energy. With the development of modern precision agriculture, precise fertilization has also developed rapidly and will become an important fertilization mode.

[0003] Fertilizers include solid waste and liquid fertilizers. Liquid fertilizers usually contain a large amount of essential nutrients such as nitrogen, phosphorus, potassium, and calcium, magnesium, iron, zinc, etc. In order to meet the needs of crops at different growth stages, some liquid fertilizers also contain amino acids and other ingredients. These ingredients help to improve crop yield and quality. In contrast, the nutrient content of solid fertilizers is relatively single, and due to low utilization rate, the nutrient content in solid fertilizers cannot be fully absorbed by crops, resulting in nutrient imbalance in the soil and affecting crop yield. Liquid fertilizers are superior to solid fertilizers in terms of nutrient richness, absorption degree, convenience of use, and nutrient utilization rate. Therefore, liquid fertilizers are increasingly widely used. However, the existing liquid fertilizers still have the following problems when used in plant cultivation:

[0004] At different growth stages of existing plants, the root length of plants in the soil changes. The operator uses a spray head to spray liquid fertilizer on the plants. During the spraying process, a part of the liquid fertilizer is sprayed on the plant leaves, and the heat easily evaporates, resulting in waste of the liquid fertilizer. The remaining part of the liquid fertilizer flows into the soil along the branches. Some plants with overlong roots cannot absorb the liquid fertilizer, which affects the cultivation effect of the plants. Therefore, it is necessary to provide an intelligent root layer infiltration irrigation and fertilization system for the existing plant cultivation field. SUMMARY

[0005] In order to make up for the deficiencies of the prior art, the length of the root system of the plant in the soil changes at different growth stages of the plant, and the operator sprays the fluid fertilizer on the plant by using the spray head. Since a part of the fluid fertilizer is sprayed on the leaves of the plant during the spraying process of the spray head, the fluid fertilizer is easily evaporated with heat, so that the fluid fertilizer is wasted, and the other part of the fluid fertilizer flows into the soil along the branches. For some plants with overgrown roots, the plant cannot absorb the fluid fertilizer, which affects the cultivation effect of the plant.

[0045] Example 2

[0046] As Figures 1-3As shown, this is a schematic diagram of an intelligent root layer drip irrigation fertilization system according to another preferred embodiment of the present invention. Liquid fertilizer enters the cultivation chamber 12 through the through-hole 61. Due to the low permeability of liquid fertilizer in the soil, some soil is also carried out by the liquid fertilizer and flows into the water storage box 53 of the operation chamber 13, causing soil loss and reducing the operation effect. Therefore, based on embodiment 1, the device is improved. Multiple filter boxes 43 are fixedly installed on the inner wall of the cultivation chamber 12.
