Abstract

The utility model relates to a daylight greenhouse concealed pipe salt discharge device which is characterized in that a leaky pipe is embedded in soil of a daylight greenhouse, a leakage hole is arranged on the leaky pipe, and the leaky pipe is communicated with a salt discharge tank. The daylight greenhouse concealed pipe salt discharge device can collect residual salt in soil, collectively gathers salt to a salt discharge well, and collectively discharges salt to a drainage ditch outside a greenhouse, greatly reduces the accumulation of salt in the greenhouse, and improves the soil environment of the greenhouse, thereby improving the yield and quality of facility horticultural plants, and prolonging the service life of the greenhouse.

Description

Heliogreenhouse hidden pipe salt discharge device

Technical field

The utility model belongs to the agricultural facility technical field, particularly relates to a kind of heliogreenhouse hidden pipe salt discharge device.

Background technology

On heliogreenhouse garden crop soil is produced, because higher, the unreasonable chemical fertilizer use of parent soil material and underground water salt content, the excessive use of farm manure, the factors such as agricultural production way to manage that fall behind cause soil salt content to raise year by year, finally cause facilities horticulture crop yield and quality to reduce.At present, generally be adopt to improve production management level, the measures such as soil, the big flood desalinization of soil by flooding or leaching, soilless culture, plantation catch crop of changing reduce soil salt content, but above-mentioned technology or owing to cost, management, all there is certain weak point in reason such as recovery easily.

Summary of the invention

Purpose of the present invention just is to overcome the defective of above-mentioned prior art, and a kind of effective soil salt accumulation that improves is provided, and improves soil quality, thereby improves the heliogreenhouse hidden pipe salt discharge device of facilities horticulture crop yield and quality.

The present invention is achieved through the following technical solutions:

A kind of heliogreenhouse hidden pipe salt discharge device is characterized in that: be embedded with leaky pipe in the soil of heliogreenhouse, have weepage holes on the described leaky pipe, this leaky pipe is communicated with the salt discharge pond;

Above-mentioned weepage holes is opened at the leaky pipe upper side.

Heliogreenhouse hidden pipe salt discharge device of the present utility model can be collected salinity unnecessary in the soil, be pooled to the salt discharge well, concentrate in the gutter that is discharged to the outside, greenhouse then, significantly reduce the greenhouse salt accumulation, improve the greenhouse soil environment, thereby improve the yield and quality of facilities horticulture crop, improve the application life in greenhouse.Because season drip irrigation is installed in production, irrigation quantity is less, desalinization of soil by flooding or leaching amount is little, can not cause the loss of available nutrient.Irrigate the salt content that can obviously reduce soil by big flood at leisure season.Experiment shows: the greenhouse soil of burying two hidden pipes underground is during the 9-12 month in 2008, January-March, the 5-7 month, and soil EC value descends 34.57%, 41.81%, 41.87%; The greenhouse soil of burying a pipeline underground has descended 28.43%, 35.44%, 21.81% respectively during the 9-12 month in 2008, January-March, the 5-7 month; With respect to the greenhouse that the salt discharge pipeline is not installed, can effectively reduce heliogreenhouse soil salt content 23.06%-29.18%.Illustrate that the greenhouse buries hidden pipe underground tangible salt discharge effect is arranged.Improve garden crop output 15.3%-23.5%, quality is obviously improved, and the economic benefit of unit area improves more than 20%.

Description of drawings

Fig. 1 is the structural representation sketch of the utility model heliogreenhouse hidden pipe salt discharge device.

The specific embodiment

Heliogreenhouse hidden pipe salt discharge device of the present utility model, be meant and in the soil of heliogreenhouse, bury leaky pipe 1 underground, the upper side of described leaky pipe 1 has weepage holes 2, this leaky pipe 1 is communicated with the salt discharge pond 3 of setting in the greenhouse, thereby the salinity of collecting is pooled in this salt discharge pond, concentrates in the gutter that is discharged to the outside, greenhouse then.

Claims

1. heliogreenhouse hidden pipe salt discharge device, it is characterized in that: be embedded with leaky pipe (1) in the soil of heliogreenhouse, have weepage holes (2) on the described leaky pipe (1), this leaky pipe (1) is communicated with salt discharge pond (3).

2. according to the described heliogreenhouse hidden pipe of claim 1 salt discharge device, it is characterized in that: weepage holes (2) is opened at leaky pipe (1) upper side.
