Description

Method for tidal irrigation of ground

Technical Field

The invention belongs to the technical field of crop irrigation, and particularly relates to a tidal irrigation method for the ground.

Background

The tide type irrigation system is a high-efficiency water-saving irrigation system designed based on the tide fluctuation principle, is suitable for planting and managing various potted plants, and can effectively improve the utilization efficiency of water resources and nutrient solution. Tidal irrigation is mainly divided into two categories, ground-based and bed-planted. The ground-type tidal irrigation system is characterized in that a seedling tray water-containing pool capable of storing water is built on the ground surface, and a plurality of water outlet holes and water return holes are distributed in the seedling tray water-containing pool. The tidal irrigation system is provided with equipment for adjusting the pH value and various nutrient concentrations of nutrient solution, and a filtering system and a disinfecting system for increasing media to prevent the nutrient solution from being excessively polluted. The industrialized rapid cutting propagation of the seedlings is one of the seedling raising modes which are commonly applied at present, has important significance for seedling production enterprises to utilize ground space and realize water and fertilizer integration, and is not in accordance with the national policy requirements on greenhouse facility land because large-area hardening is required to be carried out on the ground when the seedbed is used, so that the ground is reformed on the premise of not changing the property of agricultural land, and the ground tidal irrigation bed is necessary to be formed.

The search of the existing documents shows that Chinese patent No. CN103253489A, published 2013, 8.21 discloses a tide type irrigation seedbed frame, and the tide type irrigation seedbed frame is manufactured by adopting end face frames, side frames, end supports and cross beams. The cost required by the invention is high, and the yield of crops after irrigation is not high enough.

Disclosure of Invention

The invention aims to provide a method for tidal irrigation of the ground, which reduces the use cost and increases the yield of crops.

A method of tidal irrigation of a ground, the method comprising the steps of:

1) setting a seedbed: arranging a drainage ditch on the upper part of the seedbed, arranging a water inlet pipe on the upper part of the drainage ditch, inputting water by using the water inlet pipe, enabling the water to flow into a field to irrigate the field, and arranging a control valve on one side of the water inlet pipe to control the input water quantity;

2) and (3) seedbed irrigation: after seedbed position and scope are confirmed, lay geotechnological cloth, plastic sheeting for farming and horticulture ground cloth on it, treat potted plant and put the back on the seedbed, fertilize for potted plant and handle, give the plant with fertilizer through joining in marriage the fertile ware, supply water through circulating pump feeding pipe and joining in marriage fertile ware, the liquid manure that omits outside the seedbed after the fertilization flows into liquid manure recovery pond, unnecessary water can flow back through the wet return, accomplishes the secondary irrigation of liquid manure.

Further, the fertilizing amount is 5% -10% of the watering amount of the plants.

Furthermore, when the water return pipe flows back, filtering operation is needed, and ultraviolet rays are adopted to sterilize the water return pipe.

The invention has the beneficial effects that:

1) the invention can directly realize the integration and recycling of water and fertilizer by leveling and compacting the original ground in the greenhouse, and the covering material and the water and fertilizer integration facility are connected through the pipeline to form a large-area flat seedbed, thereby realizing the ground type tidal irrigation seedbed, improving the comprehensive utilization rate of water and fertilizer and facilitating the large-scale irrigation and use of water and fertilizer.

2) In the ground tidal irrigation, a plurality of seedbed areas can be formed in the same greenhouse, are separately controlled and are combined with the water and fertilizer integrated facility to realize the high-efficiency utilization and recycling of water and fertilizer, the environment is not polluted, the sustainable utilization is realized, the ground seedbed is simple to manufacture, the materials are easy to obtain, metal parts are not used, the production cost can be greatly reduced, and the crop yield can be improved to the maximum extent.
