Abstract
The utility model discloses an alkali device is arranged in coast saline and alkaline land cotton desalinization of soil by flooding or leaching, including arranging the salt pipe, be provided with a plurality of hole on row's salt pipe, be provided with salinity detection module on row's salt pipe. This device can be inhomogeneous with the salinity space -time in coastal saline and alkaline land, and relapse dynamic change saline and alkaline finally send the field outside, reach and reduce finally that soil is saline and alkaline, the effect in improvement cotton field. And with low costs, high -efficient, effect is showing.
Description
Technical field
The utility model belongs to farm technology field, is specifically related to a kind of coastal alkaline land cotton desalinization of soil by flooding or leaching row alkali device.
Background technology
The soil salinization is the global problem affecting agricultural production and ecotope.There is 1,000,000,000 hectares, saline land in the world, accounts for 1/4 of land; China's 3,600 ten thousand hectares (plant in cotton region and about have 1,700 ten thousand), the salinity of soil middle and high concentration causes osmotic stress and Ion toxicity to crop, thus affects the growth of crop, seriously causes crop failure.For Yancheng, Jiangsu Province, Yancheng has wide beach saline-alkali ground, floor space about 500,000 hectares, and annual still with ten thousand mu of length of becoming silted up eastwards, but the speed developed is partially slow.In order to accelerate its exploitation, just in the urgent need to cultivating the crops that can adapt to the growth of high salinity, and produce good economic benefit.In large crops, salt resistance is comparatively strong, and saline land pioneer crop-cotton is an ideal material, is the economic crops (native fiber, biomass energy, oil crop, albumen powder raw material) that can meet the need.Soil salt content is suitable for cotton and emerges, grows below 0.2%, but when soil salts density is greater than 0.3%, will produce harm to cotton.The saline land saliferous of jiangsu coast sheet is mostly more than 0.3%, except a high salt tolerant cotton material of initiative, but the more important thing is desalinization of soil by flooding or leaching salt discharge, improvement saline land, but saline land, seashore lacks the condition of a large amount of fresh water flood irrigation, and long-distance transportation cost is too high, but can by rainwater, but salinity is forced in soil after rain-out, along with transpiration is returned again on earth's surface during fine day, time rainy, be pressed onto underground again, again and again do not reach the object of the desalinization of soil by flooding or leaching once and for all.
Utility model content
Salinity space-time for coastal saline land is uneven and dynamic change repeatedly saline and alkaline, and finally sends saline and alkaline outside field; Saline land, seashore lacks the condition of a large amount of fresh water flood irrigation, and long-distance transportation cost is too high, and the utility model provides a kind of coastal alkaline land cotton desalinization of soil by flooding or leaching row alkali device.
The technical scheme that the utility model adopts is, a kind of coastal alkaline land cotton desalinization of soil by flooding or leaching row alkali device, comprises salt discharging pipe, salt discharging pipe is provided with several holes, salt discharging pipe is provided with salinity detection module.
Feature of the present utility model is also,
Salinity detection module comprises the housing of hollow, and housing is provided with single-chip microcomputer, and single-chip microcomputer is connected with salt sub sensor and display screen respectively by wire.
Salinity detection module comprises the housing of hollow, and housing is provided with single-chip microcomputer, and single-chip microcomputer is connected with salt sub sensor and display screen respectively by wire.
Salt discharging pipe is at least provided with 2.
The density in hole is 2-5/cm
2.
The caliber of salt discharging pipe is 3-4cm, and the length of salt discharging pipe is 20-30m.
The beneficial effects of the utility model are: this device by uneven for the salinity space-time in coastal saline land and dynamic change repeatedly saline and alkalinely finally send outside field, can reach the effect of finally lowering soil alkaline, improvement cotton field.The salinity detection module of this device makes salinity detect intellectuality, and cost is low, efficient, Be very effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model coastal alkaline land cotton desalinization of soil by flooding or leaching row alkali device;
Fig. 2 is the structural representation of the utility model salinity detection module.
In figure, 1. salt discharging pipe, 2. salinity detection module, 3. hole, 4. housing, 5. single-chip microcomputer, 6. salt sub sensor, 7. display screen.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
The utility model provides a kind of coastal alkaline land cotton desalinization of soil by flooding or leaching row alkali device, as shown in Figure 1, comprises salt discharging pipe 1, salt discharging pipe 1 is provided with several holes 3, salt discharging pipe 1 is provided with salinity detection module 2.As shown in Figure 2, salinity detection module 2 comprises the housing 4 (preventing the electric elements of its inside by water or other Hquid) of hollow, and housing 4 is provided with single-chip microcomputer 5, and single-chip microcomputer 5 is connected with salt sub sensor 6 and display screen 7 respectively by wire.Salt discharging pipe 1 is at least provided with 2.The density in hole 3 is 2-5/cm
2.The caliber of salt discharging pipe 1 is 3-4cm, and the length of salt discharging pipe 1 is 20-30m.
The operating process of this device is as follows: the sowing cotton seed mode in coastal saline land generally adopts live, this desalinization of soil by flooding or leaching salt discharge device was embedded in (by the end of May, at the beginning of 6 months) 1-2 month 10-20cm under surface layer prior to seeding, and line-spacing, spacing in the rows need be stopped, general alkaline land cotton line-spacing 60-80cm, spacing in the rows 30-40cm; Establish 1 salt discharging pipe 1 between the cotton seedling of every two row, (density can be 2-5/cm to leave some holes 3 above
2), object saline and alkaline in soil is gathered in hole 3 by rainwater, thus be discharged to outside field by this device, reaches the improvement saline and alkaline effect in cotton field; Establish 1 salt discharging pipe 1 between the cotton seedling of every two row, salt discharge device is to cotton spacing from about 30-40cm; The caliber of salt discharging pipe 1 is 3-4cm, the length of salt discharging pipe 1 is 20-30m; Salinity is discharged to after outside field, can ditch and be introduced into korneforos; Salinity detection module 2 detects cotton field salinity by salt sub sensor 6, and its testing result is passed to single-chip microcomputer 5, and shown by display screen 7, be reduced to 0.2%-0.3% (in large crops cotton comparatively salt-tolerant drought-resistant) rear removable device below until cotton field salinity.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.
