Flow-limiting maintainable fertigation underground water-injecting needle

Abstract

The invention particularly relates to a flow-limiting maintainable fertigation underground water-injecting needle, which belongs to the technical field of plant irrigation. The flow-limiting maintainable fertigation underground water-injecting needle comprises a water-injecting pipe, and is characterized in that a flow-limiting water conveying connector with a flow-limiting water conveying hole in the middle is arranged on the upper part of the water injection pipe; a water injection needle head is arranged at the bottom end of the water injection pipe and is composed of a dirt storage cavity in plug-in connection with the water injection pipe, a tapered head connected with the dirt storage cavity and a pipe hoop sleeving the dirt storage cavity; the upper part of the pipe hoop is provided with one or more than one water outlet holes; and the water injection pipe is communicated with the dirt storage cavity. The flow-limiting maintainable fertigation underground water-injecting needle is a further improvement of a conventional water-injecting needle, enables pressures of a water head and a water tail of an irrigation network to maintain stable, facilitates cleaning of deposited obstructions and maintenance, and has the advantages of long service life, a wide applicable range and capacity of realizing water-saving and highly-efficient irrigation technology.

Description

technical field [0001] The invention belongs to the technical field of plant irrigation, in particular to a flow-limiting and maintainable underground water injection needle for irrigation and fertilization. Background technique [0002] In the current irrigation industry, especially in the fields of fruit trees, greenhouses, gardens, etc., methods such as sprinkler irrigation, drip irrigation, and small tube outflow are basically ground irrigation methods, which are improved compared with traditional methods, but there are still wastes of water. Disadvantages such as fast volatilization and easy clogging. Especially the drip irrigation with the largest amount of use, due to the influence of the water quality in the field, leads to frequent clogging, and it can no longer be used after one year of use. The drip irrigation equipment originally designed to last for several years is basically scrapped after one year of use. , so that drip irrigation is not suitable for large-sc...
