Orchard interplanting crop micro-irrigation device

Abstract

The invention discloses an orchard interplanting crop micro-irrigation device which comprises a cylindrical rain trap. A plurality of rain collecting parts are arranged on the peripheral side of the rain trap, a water inlet is formed in the outer circumferential surface of the rain trap and positioned above the rain collecting parts, a filter screen is fixedly arranged on the outer circumferential surface of the rain trap and positioned among the rain collecting parts and the water inlet, a drip irrigation capillary pipe is mounted at the bottom of the rain trap, and drip irrigation emitters are uniformly arranged on the drip irrigation capillary pipe. Natural rainfall in an orchard can be automatically collected, the irrigation modes of micro-spray irrigation and drip irrigation can be selected, irrigation water use efficiency can be improved, and the orchard interplanting crop micro-irrigation device is mounted on a fruit tree trunk without occupying growth space of fruit trees and interplanting crops.

Description

technical field [0001] The invention belongs to the technical field of irrigation devices, and relates to a micro-irrigation device for orchard interplanting crops. Background technique [0002] Water is an essential substance for the growth of crops. The total amount of water resources in my country is large, but the total amount of available fresh water resources is scarce. Agriculture is the industry that accounts for the largest proportion of water consumption in my country. With the development of my country's industry, the problem of water resource shortage is becoming more and more serious. It is becoming more and more prominent and poses a serious threat to agricultural water security. The use of more efficient water-saving irrigation equipment can not only improve the efficiency of agricultural water use and alleviate the current shortage of water resources in my country, but also reduce agricultural production costs and improve agricultural production efficiency to ...

Problems solved by technology

[0004] At present, there are few related patents related to water-saving irrigation devices specially used for interplanting crops in orchards. Most of them use capillary pipes in the field, and use drip irrigation or sprinkler irrigation for irrigation. Some still use the original natural rainfall method. Related patents include: Chinese invention patent "Rain-harvesting and Drought-Resistant Cultivation Method of Trees in Arid and Semi-arid Areas" (Application No.: 201510326104.6, Publication Date: 2015-09-16, Publication No.: CN104904561A), is mainly to ditch the soil at the roots of trees along the rows of trees and Mulching, this method is not suitable for interplanting crop irrigation in orchards; Chinese invention patent "Intelligent seepage irrigation system for orchard belts" (application number: 201410044149.X, publication date: 2015-07-29, publication number: CN104798666A) , is to measure the soil moisture content by burying soil moisture sensors in the roots of trees, and manage orchard irrigation according to the measured values. This method has high operating costs and is not easy to use for interplanting crops with more developed root systems; Hanging and under-tree micro-sprinkler irrigation system" (Application No.: 201511016205.X, Publication Date: 201511016205.X, Publication No.: CN105638385A), which uses a water source water supply method, which is difficult to promote and use in mountainous and hilly areas where water resources are scarce; Chinese invention The patent "A method for deep infiltration of rain-collecting tree trays in apple orchards in arid plateau areas" (application number: 201610394950.6, publication date: 2016-10-26, publication number: CN106034914A) is to bury a rain collector on the soil surface, and then For root irrigation, because the rain collector needs to occupy a certain amount of land and the rain collection efficiency is low, it is not easy to use this method for interplanting crops; the Chinese invention patent "Mist control method and mist irrigation device for fruit expansion period in arid areas "(Application No.: 201510636265.5, Publication Date: 2015-11-18, Publication No.: CN105052682A), which can improve the utilization efficiency of irrigation water and increase fruit yield, but the device has a relatively large operating power, and the water supply of the device adopts the water source supply method ,higher cost

[0005] Most of the devices and methods mentioned above are irrigated by means of water supply, and most of them are suitable for non-interplanted fruit tree crops, and less consideration is given to the interplanted crops below the fruit tree. At the same time, the operation of these devices requires a large energy, high cost, and difficult to promote in mountainous and hilly areas
