Abstract
The invention relates to a utilizing method of saline-alkali soil surface water, and belongs to the field of high-technique agricultural cultivation. The method comprises the design of a collecting basin and the selection of water-improving substrate. The utilizing method is characterized in that firstly, the collecting basin is excavated in the saline-alkali soil, the width and the depth of the collecting basin are confirmed after being accumulated based on the local rainfall and the area of a water gathering ground, the volume of the collecting basin can accommodate the surface runoff in a planning agriculture-and-forestry planting area after 1 to 2 times of heavy rain, and at the same time, a certain proportion of maize straws and waste anricularia-bran are placed into the collecting basin. When high temperature sustains for a certain time in summer, the water in the collecting basin can be used for irrigation and water supplement in arid season, and the water also can be used for irrigation and moisture conservation in autumn-winter. According to the utilizing method of saline-alkali soil surface water, the biotransformation technology is adopted to conduct neutralization on saline-alkaline water of the runoff in the saline-alkali soil, the agriculture-and-forestry planting area is guaranteed to be free from the backflow of saline-alkaline water, the surviving rate of a planted target plants is improved, the nature rainfall is also utilized effectively, the irrigation cost is saved, at the same time, the soil fertility can be increased greatly when the maize straws and waste anricularia-bran in the collecting basin are recycled, and the environment is cleaned.
Description
Art:
The invention belongs to the field of agricultural cultivation of new and high technology, particularly the efficiency utilization measure of a kind of salt-soda soil surface water and rural surplus thing.
Background technology:
Along with the continuous increase of industrial expansion and population, be becoming tight by day for freshwater resources.Therefore, the waste water resources such as development and utilization brackish water, salt water and low mineralising alkaline water carry out agricultural irrigation, are to alleviate current shortage of water resources, improve grain yield, slow down the important content of population, grain, resources and environment contradiction.Salt-soda soil is saline and alkaline because surface flow is rich in, and plant can not directly absorb, and has to pass through certain measure process, is mainly undertaken by lab simulation and field test at present to the research of this respect.
Publication number be CN103723847A patent describes a kind of agricultural irrigation water demineralization plant, comprise water pump, strainer, reverse osmosis unit and water-water jet, although the method can make the agricultural drain of Arid&semi-arid area and brackish water effectively be recycled, but equipment investment is large, also by restrictions such as electric power.
Publication number be CN203984952U patent describes a kind of novel salt-soda soil water and soil improved system, comprise hidden pipe, micro-filtration water hole, filtration beds, plantation soil layer, shower buried regions, shower and cloudy well, the method is conducive to improving the sprinkling efficiency and filter effect, strengthens the effect of desalinization of soil by flooding or leaching desalination, make desalinization of soil by flooding or leaching homogenising, but there is the problem of high cost in the method.
Publication number be CN203788669U patent describes a kind of salt-soda soil water circulation system with salt discharge alkali function, comprise some surface storage pipes be obliquely installed, the inner of this surface storage pipe inserts in surface storage well, be respectively equipped with salt discharging pipe assembly in the inner of every root surface storage pipe, improved effect is better.But the method is also comparatively tight to equipment requirement, is easy to damage.
Publication number is that CN102523773A patent describes that a kind of improvement salt-soda soil paddy field bed is anti-to be soaked into and salt discharge buck device, by paddy field bed, ridge stage body, prevent soaking into plastics mold layer, saturating saline-alkali water filter mantle, gutter, valve is formed, this method prevent natural salt alkaline earth to accumulation of salt in the surface soil alkali in paddy field bed, man-made irrigation in paddy field bed washed out containing saline and alkaline water, enter in depth of water ditch from gutter, natural salt alkaline earth, saline-alkali water can be gone out with the sprinkling of rainfall, enter in draining zanjon from saline-alkali water soil, the method only relates to paddy planting, to dry farming, forestry etc. are inapplicable, operation also comparatively bothers.
Publication number be CN202503890U patent describes a kind of salt-soda soil water and soil improved system.This method provide a kind of system burying the improvement salt-soda soil of hidden pipe underground, although the method effectively controls groundwater quality, the underground water that timely eliminating salt content is high, effectively prevent accumulation of salt in the surface soil phenomenon, but the costs such as the hidden pipe that system relates to, filtration beds, haydite are higher, and just for underground water, do not relate to surface water.
Saline-alkali Field Control is global problem, also a lot of to the report of salt-soda soil water conservancy, the international improvement of salt and alkaline land academic discussion of the Chen Xiu tinkling of pieces of jade 1985 Nian is reported and has carried out Salt water irrigation situation in Eastern Hebei Plain Nanpi examination district, point out to utilize the key problem in technology of irrigation with saline water to be control salt accumulation in soil to be no more than crop tolerance to salt degree, in the anniversary, salification does not occur.The Zhang Yongbo soil journal result of study of 1997 is pointed out at the suitable irrigation norm of irrigated area, Yuncheng Basin lake region salt water.External correlative study is also pointed out, according to the requirement of drip washing water requirement, regulation and control pours into the water yield and salt amount, and topsoil soils salinity can be kept to be no more than setting, and heavy irrigation can be avoided again to cause groundwater table to rise.
Summary of the invention:
The object of the invention is that according to salt-soda soil surface water be alkalescence, maize straw and waste mushroom leftover are acid and are rural surplus discarded object, the feature neutralized can be carried out, provide the method for a set of salt-soda soil urface water usage, Saline-alkali Field Control is carried out at China's song-Nen plain saline-alkaline, for saving water resource, improve rural surplus waste utilization rate, Environment control provides new approaches.
In order to achieve the above object, the technical solution used in the present invention comprises: first on salt-soda soil, excavate collecting-tank, collecting-tank width and the degree of depth are determined according to after local amount of precipitation and catchment areal calculation, its volume can hold the surface flow in plan agriculture and forestry growing area after 1-2 heavy rain, in collecting-tank, place a certain proportion of maize straw and waste mushroom leftover simultaneously, after summer high temperature certain hour, water in collecting-tank can be used for carrying out irrigation moisturizing at arid season, irrigation soil moisture conservation can also be carried out in autumn and winter, can effectively increase soil fertility after maize straw in collecting-tank and bacterium chaff reclaim, cleaning of environment.
Collecting-tank can be determined according to actual conditions, and agricultural planting district, Plain can be designed to square, and the trees green area of road both sides can be designed to bar shaped.
Collecting-tank size, plains region per hectare collecting-tank length and width and the degree of depth can be designed to 3m × 3m × 3m, and the width of road both sides and the degree of depth can be designed to 2.5-3m × 1.5m, and length extends naturally with road.
Maize straw is 1:5 with the ratio of the pool inner water that catchments, and waste mushroom leftover is 1:5 with the ratio of the pool inner water that catchments, and increases and decreases at any time according to the volume of the pool inner water that catchments.
