Buried water and fertilizer integrated device used for vegetable planting and vegetable planting method thereof

Abstract

The invention discloses a buried water and fertilizer integrated device used for vegetable planting. The buried water and fertilizer integrated device used for vegetable planting comprises a main pipe, side pipes, control pieces and adjusting ropes, wherein the main pipe is an arc pipe, a middle position of the main pipe communicates with a water and fertilizer delivery pipe, and multiple openingswhich communicate with the interior of the main pipe are formed in the side wall of the main pipe; the side pipes are flexible pipes or elastic pipes, the multiple side pipes are arranged on two sides of the main pipe, and correspondingly communicate with the openings in a one-to-one mode, a root growing space is defined by the multiple side pipes located on the two sides of the main pipe, and aplurality of seepage openings are formed in the side surface, facing the root growing space, of each side pipe; the number of the control pieces is two, both the control pieces are located in the mainpipe, the outer peripheral walls of the control pieces abut against the inner wall of the main pipe, and the control pieces can move among ends of the main pipe and the water and fertilizer deliverypipe in an axial direction of the main pipe; and the adjusting ropes are connected with the side pipes. According to the buried water and fertilizer integrated device used for vegetable planting, through cooperation of the arc main pipe and the side pipes, wrapped irrigation is formed for roots, the buried water and fertilizer integrated device used for vegetable planting is especially suitable for vegetables with developed lateral roots, and good water and fertilization irrigation is formed for all the roots.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer integration, in particular to a buried vegetable planting water and fertilizer integration device and a vegetable planting method thereof. Background technique [0002] Water and fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. It uses a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the law and characteristics of crop types. The mixed fertilizer solution and irrigation water are supplied with water and fertilizer through the pipeline system, and are evenly and accurately transported to the root area of ​​the crop. Water and fertilizer are supplied through the controllable pipeline system. After the water and fertilizer are mixed, the drip irrigation is formed through the pipeline and the dripper, uniformly, regularly and quantitativel...

AI Technical Summary

Problems solved by technology

[0003] For vegetable irrigation, most of the current water and fertilizer integration is to directly distribute drip irrigation pipes or sprinkler irrigation pipes equidistantly, to irrigate the roots of vegetables without distinguishing vegetable varieties, and the pertinence is weak, especially for some vegetables with well-developed lateral roots, such as tomatoes. At this time, a certain distance is required to adapt to the growth of the root system. At this time, the drip irrigation pipe in the traditional water and fertilizer integration cannot adapt to the growth of the plant root system for watering, resulting in waste in the early stage and may not be covered in the later stage.
