Abstract
The invention discloses a method for improving coastal saline soil by gathering rain water and suppressing evaporation. The method comprises the following steps: 1) fertilization: applying organic fertilizers and superphosphate; 2) plough: ploughing the soil to a depth of 15 to 30; 3) cofferdam building and land leveling: raising a network of soil ridges to form land pieces in different sizes and leveling each land piece encircled by the ridges; 4) covering plastic film: covering each land piece encircled by the ridges with a plastic film which has a plurality of pores for allowing rain water to flow into soil to wash off salts in the soil; 5) planting sesbania in the pores which can fertilize soil, cover plant residue, reduce land-surface evaporation and slow down the aging of the plastic film. The method, when large amount of fresh water is not available, can use rain water and a rain water gathering and evaporation suppressing agricultural technology to reduce salt content in the coastal saline soil effective and improve and use the coastal saline soil.
Description
Technical field
The present invention relates to a kind of method of improvement of salt and alkaline land, specifically a kind of method of collecting rain, suppressing steaming and improving coast saline soil.
Background technology
The main reason of the soil salinization: be that weather arid, impeded drainage and the degree of mineralization of ground water are too high, " height " that promptly it has often been said, " greatly ", " having "." height " is the subterranean water level height, soil has the hollow billet water sorption, general soil hollow billet suction head is about 1.5 meters, if subterranean water level is higher than 1.5 meters, phreatic salinity will be with the face of land that is raised to waterborne, moisture is evaporated, salinity has just been stayed the face of land, and salinity surpasses finite concentration, just crop is worked the mischief, form saline soil, the subterranean water level height mainly is that impeded drainage causes; " greatly " is that soil evaporativeness is big, and a large amount of soil moisture of evaporation discharge ambassador is evaporated, and the salinity in the water is accumulated in table soil, forms saline soil, and soil evaporativeness is caused by the weather arid greatly; " having " is that salt that is degree of mineralization of ground water height are arranged in the underground water, and many Plains of China all are the ground that moves back the sea, all contain salt in the soil body and the underground water, is the basic reason that saline soil forms.
The main ameliorative measure of strand salinization soil at present:, multiple improving technology and measure are arranged according to the origin cause of formation of saline soil.At " height ", promptly the subterranean water level height mainly adopts engineering measure, and as the mediation drainage river channel, to perfect the farm field irrigation drainage system, repair raised fields etc. all be effective method, " going up fishing under the grain " pattern of Shandong Province Dongying city peasant is exactly a kind of development of raised fields at present; At " having ", promptly in the underground water or the soil body salt is arranged, mainly adopt the washing salinity by irrigation method, by pouring water, the salinity of upper soll layer is moved to soil body deep layer, and the salt content of topsoil is reduced to can plant growth, draws yellow the irrigation and all washing salinity by irrigation methods of irrigation and drainage by well.In high mineralization groundwater province, strand, adopt " take out salty change light, agricultural salt in conjunction with " the method improvement beach salty soil, both having extracted high mineralization underground water evaporates brine, lowering of watertable, underground water are upgraded by fresh water gradually, are the new methods that reduces the soil body and underground water salinity; Adopt the method for " drip irrigation salt washing and controlling quick improvement saline soil ", under the less situation of water consumption, crop root zone soil desalination fast is suitable for plant growth, is the new method that reduces soil body salinity.At " greatly ", the method that mainly adopts the face of land to cover as plastic mulching and stalk covering etc., covers by the face of land, reduces evaporation from topsoil, also just reduces salinity and assembles to the face of land.Plastic mulching plant cotton in saline land is a very successful technology, in China landlocked and beach saline land to apply area all very big.Beach salty soil is mainly pressed the method for salt by a large amount of fresh water desalinization of soil by flooding or leaching at present, still, does not have improvement method substantially at the local saline soil that does not have fresh water.
Summary of the invention
Technical assignment of the present invention provides a kind of content that can effectively reduce salinity in the beach salty soil, improves the method for the collecting rain, suppressing steaming and improving coast saline soil of soil constituent.
Technical assignment of the present invention realizes that in the following manner this method may further comprise the steps,
1), fertilising: organic fertilizer and superphosphate in beach salty soil;
2), plough: 15-30cm is dark with the beach salty soil tractor-ploughing;
3), leveling soil, cofferdam:, form the field piece that differs in size with the latticed low bank of earth between fields that impales of beach salty soil; In the field piece that each low bank of earth between fields impales, flatten;
4), covering with plastic film: covering with plastic film in the field piece that each low bank of earth between fields surrounds, have a plurality of apertures on the mulch film, can make precipitation flow into soil, the washed out soil salinity by aperture;
5) also can play plant residue and cover, the sesbania that reduces surface evaporation and slow down the plastic foil aging action, plantation can fertilizing soil in the aperture of mulch film.
Described every mu of organic fertilizer 5000-10000 kilogram, superphosphate 50-100 kilogram.
The height of the described low bank of earth between fields is 10-20cm.
The method of collecting rain, suppressing steaming and improving coast saline soil of the present invention is not having under the situation of a large amount of fresh water, has effectively reduced the content of salinity in the beach salty soil according to precipitation, has improved soil constituent, has improved the value of beach salty soil.
