Embodiment 1

[0081]The invention is divided into an irrigation subsystem, a preparation nutrient solution subsystem and a control subsystem. The irrigation subsystem waters the plants at the drip irrigation point, and the preparation nutrient solution subsystem prepares the plant growth nutrient solution and modulates the pH and totality of the nutrient solution. Concentration, the irrigation subsystem fertilizes the plants at the drip irrigation point, the control subsystem regularly and quantitatively controls the irrigation subsystem to irrigate the plants at the drip irrigation point, adjusts the appropriate nutrient solution according to the fertilizer demand of the plant, and converts it into water volume. Fertilize the plants at the drip irrigation points.

[0082] It consists of a reservoir (8), a water diversion pump (7), a water supply pipeline (31), a water injection pipeline (17), a storage nutrient solution output pipeline (29), a nutrient solution storage tank (21), and a nutr...

Embodiment 2

[0084] The other end of the water supply pipeline (31) is connected to the water inlet of the irrigation control valve (11), and one end of the main delivery pipeline (4) is connected to the water outlet of the irrigation control valve (11). The control switch of (11) is connected with the main controller (30), and the opening and closing of the irrigation control valve (11) controls the delivery of the water source in the reservoir (8) to the main delivery pipeline (4).

[0085] The branch pipeline (5) is connected with the main delivery pipeline (4), at least 4 branch pipelines (5) are installed on the main delivery pipeline (4), and one end of the branch pipeline (5) is installed in the field Control valve (16), each branch pipeline (5) controls the irrigation and fertilization of a unit group of drip irrigation points (14), whether the opening and closing of the field control valve (16) is opened and closed one branch pipeline (5), Each branch pipeline (5) transports the i...

Embodiment 3

[0088] The upper part of the supporting and positioning jig (2) is a snap ring (12), and the snap ring (12) covers the loop closed group flow drip irrigation pipeline (1), and the lower part of the supporting and positioning jig (2) is a positioning cutting rod (13). The cutting rod (13) is inserted in the drip irrigation point (14), the loop closed group flow drip irrigation pipeline (1) is fixed and positioned at the drip irrigation point (14) through the support positioning fixture (2), and the loop closed group flow drip irrigation pipeline (1) The dripper (15) on the top implements drip irrigation around the plants, such as figure 2 , image 3 , Figure 4 shown.

Abstract

The invention relates to an irrigation method of a closed-loop group flow drop irrigation, preparation and fertilization system, a nutrient liquid preparation method and a fertilization method. The system is divided into an irrigation subsystem, a nutrition liquid preparation subsystem and a control subsystem and is composed of an impounding reservoir, a water division pump, a water source transportation pipeline, a water injection pipeline, a stored nutrient liquid output pipeline, a nutrient liquid storage tank, a nutrient liquid transportation pipeline, a nutrient liquid mother solution storage tank, an acid / base solution storage tank, a self-priming pump, a main controller, a main transportation pipeline, a branch pipe pipeline, a capillary pipeline, a supporting and positioning fixture, a flow stabilizer, a closed-loop group flow drop irrigation pipeline and water droppers, wherein the water source transportation pipeline is connected with the water injection pipeline and the main transportation pipeline; the main transportation pipeline is provided with the branch pipe pipeline; the branch pipe pipeline is provided with the capillary pipeline; the capillary pipeline is provided with the closed-loop group flow drop irrigation pipeline; and the closed-loop group flow drop irrigation pipeline is provided with the water droppers, and one water dropper is arranged on each drop irrigation point. The system disclosed by the invention is scientific in design, reasonable in structure and easy and simple to operate, and has the characteristics of remarkable property, strong function, low price and obvious benefits.

Description

technical field [0001] The invention relates to a drip irrigation watering and fertilization preparation device for agriculture, forestry, gardens and greenhouses, in particular to a closed-loop group flow drip irrigation preparation and fertilization system, an irrigation method, a nutrient solution preparation method and a fertilization method. Background technique [0002] my country's facility agriculture is developing rapidly, but compared with the Netherlands, Israel and other countries, there is a big gap in management level, which is mainly reflected in: [0003] 1. The irrigation water of drip irrigation products is uneven; at present, part of the irrigation of potted plants in facility agriculture adopts drip irrigation, that is, a drip irrigation device is inserted into the substrate of each flower pot, and the drip irrigation device can only moisten the substrate around the drip irrigation when watering , The whole pot of substrate cannot be completely wet. Due ...
