Abstract
The invention discloses a simple and fast desalting method of sandy heavy saline soil. The simple and fast desalting method includes leveling saline-alkali soil; arranging draining canals, covering straws, cleaning ditches and the like. The simple and fast desalting method is characterized in that the soil is covered with wheat straws or barley straws, and the natural concentrated rainfall feature in the coastal area is fully utilized, thus the coastal sandy saline soil is fast desalted. The simple and fast desalting method is easy and convenient to operate, low in cost and high in application value and can be widely applied to fast desalting of the sandy saline soil in the coastal beaches of Jiangsu province, and therefore large-scale crop cultivation is facilitated to improve utilization potential of the beaches.
Description
Technical field
The present invention relates to a kind of method of sand strongly salined soil quick desalination.
Background technology
Salt adverse circumstance is one of principal element affecting plant growth and crop yield, is also the one of the main reasons of crop failure.The area of saline-alkali soil is very large in the world, accounts for 6.5% of the gross area.China's saline soil gross area is about 3.6 × 107 hm2, account for that the whole nation can utilize land area 4.88%, main integrated distribution in northwest, North China and Northeast China region and coastal area.China's arable land medium salting area reaches 9.209 × 106 hm2, accounts for the 6.62%(whole nation overall survey of soil office of national arable area, 1998).Along with the expansion of agricultural irrigation area, the further propelling of industrialized agriculture, soil secondary salinization will become even more serious.When China ploughs wretched insufficiency at present, exploitation salinization soil resource, improves the ecological environment, and bringing more land under cultivation is the reality need improving total grain output and agricultural sustainable development.
Long-term saline land Comprehensive Treatment Practice shows, the measures such as river construction measure, agrotechnical measures, biological control measure and chemical modifying all have certain effect to the salt reduction in saline land, soil melioration tool.In various technical measures, comparatively extensive with the application of Drainage of salt technology.The measure adopted mostly is farmland open channel or hidden pipe or shaft well irrigation and drainage etc., it is many that these technical measures also exist consumption water resource in large-scale application is promoted, project scale is large, land occupation is many, investment is many, and maintenance work amount is comparatively large, and the problems such as operation and maintenance cost is higher (Ministry of Water Resources. agricultural drain technical specification. Beijing: Chinese Water Conservancy water power publishing house, 1999,96-98).In short supply in view of China's water resource, and some Saline-alkali Field Control measures investment is comparatively large, is difficult to large scale application.
Summary of the invention
The object of the present invention is to provide a kind of Littoral Jiangsu Province rainwater resource that fully excavates to enrich and a large amount of available agricultural straw resource, take improving straw mulching as the straightforward procedure of the sand strongly salined soil quick desalination of the quick salt reduction of core.
Technical solution of the present invention is:
A straightforward procedure for sand strongly salined soil quick desalination, is characterized in that: comprise the following steps:
(1) layout of the smooth and escape canal in saline land: the beach that Littoral Jiangsu Province has been enclosed and cultivated, by long 500-600m, wide 50-60m mono-piece of bar field completes the auxiliary construction on irrigation canals and ditches road, and north-south, bar field is arranged; Repair provisional sublateral canal and Mao Gou in bar field, then with ridge, the plot between sublateral canal and hair ditch is separated into some lattice fields, the long 100m in lattice field, in lattice field, press the wide excavation drain ditch of 4-5m furrow; The inner discrepancy in elevation of smooth rear Dryland field in soil is in 30-50cm, and the local relief discrepancy in elevation is at 10-15cm; The inner discrepancy in elevation in rice check field is ± 3cm;
(2) improving straw mulching period and overlay capacity: collect wheat or Barley straw, improving straw mulching is carried out in plaid matching field, and the annual 3 ~ April before rainy season set completes improving straw mulching work, should complete at the latest before May 10;
(3) there is the rainfall of 450-750mm the 5-9 month Littoral Jiangsu Province after improving straw mulching, and the beach of topsoil salt content 10-15g/kg is down to 1-3g/kg;
(4) ditch cleaning reason moisture in the soil: because Coastal beach soil sand is strong, rainy season easily blocks dead furrow because of water and soil loss, timely ditch cleaning reason moisture in the soil promotes draining.
The present invention utilizes wheat or Barley straw to cover, and makes full use of the feature in coastal natural rainfall quantity set, finally reaches the object of the quick salt reduction of the coastal solonchak of sand partially.It is simple, convenient that this technology has operating procedure, and cost drops into the advantage relatively low, replicability is strong.Therefore, this technological invention can be widely used in the quick desalination of tidal flat of Jiangsu Province sand solonchak partially, and then large-scale planting crops, to improve the Exploitative potential of beach.
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A straightforward procedure for sand strongly salined soil quick desalination, comprises the following steps:
(1) layout of the smooth and escape canal in saline land: the beach of having enclosed and cultivated for Littoral Jiangsu Province (selects tidal flat of Jiangsu Province sand strongly salined soil as objective for implementation, salt content is at more than 10g/kg), by long 500-600m, wide 50-60m mono-piece of bar field completes the auxiliary construction on irrigation canals and ditches road, and north-south, bar field is arranged; Repair provisional sublateral canal and Mao Gou in bar field, then with ridge, the plot between sublateral canal and hair ditch is separated into some lattice fields, the long 100m in lattice field, in lattice field, press the wide excavation drain ditch of 4-5m furrow; The inner discrepancy in elevation of smooth rear Dryland field in soil is in 30-50cm, and the local relief discrepancy in elevation is at 10-15cm; The inner discrepancy in elevation in rice check field is ± 3cm; By land readjustment, can rainwash be reduced, make precipitation can relatively uniform under ooze the desalinization of soil by flooding or leaching.
(2) improving straw mulching period and overlay capacity: collect wheat or Barley straw, improving straw mulching is carried out in plaid matching field, and the annual 3 ~ April before rainy season set completes improving straw mulching work, should complete at the latest before May 10; Improving straw mulching greatly can reduce rainwater (especially when heavy rain, the heavy rain) runoff on earth's surface, ensures most of along soil profile evenly downward leaching.
(3) main cause that marine solonchak can not get improveing for a long time be Littoral Jiangsu Province " ratio falls in steaming " (i.e. the ratio of unit interval (as year) interior water evaporation quantity and rainfall) greatly, calculate according to meteorological data, Coastal Area of Jiangsu Province is steamed and is fallen than being 1.31-2.30, average 1.545.Improving straw mulching significantly can reduce the evaporation of soil moisture, according to test overlay capacity with 1-3 kg/m
2be advisable, i.e. 10-30 t/hm
2.There is the rainfall of 450-750mm 5-9 month Littoral Jiangsu Province after improving straw mulching, and the beach of topsoil (0-40cm) salt content 10-15g/kg is down to 1-3g/kg;
(4) ditch cleaning reason moisture in the soil: because Coastal beach soil sand is strong, rainy season easily blocks dead furrow because of water and soil loss, timely ditch cleaning reason moisture in the soil promotes draining.
