Plot experiment fertilization system for fertilizer drip irrigation and installation method of plot experiment fertilization system

Abstract

The invention discloses a plot experiment fertilization system for fertilizer drip irrigation and an installation method of the plot experiment fertilization system. The plot experiment fertilization system comprises a drip irrigation pipeline and a fertilization pipeline. The drip irrigation pipeline comprises PVC soft belts, pipeline communicating pieces, a ball valve and drip irrigation belts. The fertilization pipeline is connected to the drip irrigation pipeline in parallel and comprises a fertilization tank, material conveying pipelines and pipeline communicating pieces. The fertilization tank is provided with a water inlet, a water outlet, a drainage outlet and a charging opening. The water inlet is connected with one material conveying pipeline and a branch pressure ball valve I through a lock catch elbow. The branch pressure ball valve I is connected to the water inlet end of the ball valve in the drip irrigation pipeline through a spigot and socket tee. The water outlet is connected with the other material conveying pipeline and a branch pressure ball valve II through a lock catch elbow. The branch pressure ball valve II is connected to the water outlet end of the ball valve in the drip irrigation pipeline through a spigot and socket tee. Reasonable model selection is conducted on the pipeline fittings and the connecting pieces in the system, so that the problems that existing plot experiment fertilization systems are nonuniform and inaccurate in manual fertilization, and incomplete fertilization, fertilizer leakage and water leakage are severe are solved, and the experiment accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of drip irrigation, and relates to an experimental scientific fertilization system for crops, in particular to a fertilization system for drip irrigation and fertilizer plot experiment and an installation method thereof. Background technique [0002] Fertilizer is an important factor affecting the growth and yield of crops; as an important part of precision agriculture, precision fertilization is an effective way to reduce agricultural input, improve the quality of agricultural products, and reduce environmental pollution. In actual agricultural production, in order to pursue high crop yield, unreasonable and blind excessive fertilization is common. Massive fertilization not only fails to increase crop yield, but brings a series of environmental problems. Under the condition of ensuring the high yield of crops, proper supply of fertilizers and the effective distribution of materials in various organs while e...

AI Technical Summary

Problems solved by technology

Improper connection method of the device will cause serious water leakage in the pipeline, and the fertilizer cannot be fully applied, which will affect the accuracy of the test and waste manpower, material and financial resources

[0003] In the existing agricultural scientific research fertilizer tests, especially in the process of small-area fertilizer tests, there are artificial ditching and fertilization, uneven fertilizer application, inaccurate fertilization, fertilizer cannot be completely applied to the test plot with water, water leakage at joints, Serious fertilizer leakage and high labor input costs; the above problems will not only affect the accuracy of the test, but also have a great impact on the results analysis and standardized management of scientific researchers; at the same time, the low quality of fertilization will affect the growth management of crops in the middle and late stages , reducing the accuracy of the test
