Abstract
The invention discloses a method for governing and improving soda saline and alkaline land through magnet tailing composite modifying agents. Tourmaline powder is accommodated in multiple-hole small cloth bags connected to a long rope and is evenly scattered onto a paddy field surface to make the paddy field surface make sufficient contact with tourmalines, water is completely drained after 4-5 days of field soaking, fresh water is supplemented, soaking is carried out 4-5 days, water is drained, salt leaching is carried out, and the modifying agents are applied, wherein the modifying agents are formed by mixing magnet tailing powder, fermented organic fertilizer and furfural residue; water filling, field harrowing, mud making and transplanting are carried out, and conventional rice cultivation technological management is carried out. The tourmalines are utilized to improve the salt leaching effect and quickly reducing salinity, and water drainage and salt leaching carried out before transplanting is carried out on the soda saline and alkaline land aim to quickly reduce salinity. Because saline-alkali soil is covered with the magnet tailing powder, physical properties of the soil can be changed, rain can more easily infiltrate downwards, surface soil salt can be leached, soil becomes rough in texture, and salt and alkali recovery is prevented. A drip line rises, water can not arrive at the ground directly easily, and salt is prevented from accumulating towards the earth surface. Poor physical characteristics like coldness, poor permeability and adhesion of alkali land are improved, less salt can rise, the soil is loosened, the saline and alkaline land is well improved, and secondary salinization is avoided.
Description
technical field:
The invention provides a kind of magnet mine tailing composite modifying agent and administer improvement soda alkaline land method, belong to agromelioration technical field.
technical background:
The salinization of soil is a global problem, the basic reason of the salinization of soil is the problem of soil degradation, thereby cause great loss to agricultural production, therefore how improveing and utilizing large-area saline land Developing Sustainable Agriculture is significant problem in the urgent need to address with agricultural science and technology in the world.Alkaline land improving is not only uncultivated land alkaline land improving, is also to an exploration and practice of tilth salinization countermeasure.
Alkaline land improving its essence is the improvement of the ecological environment of Soil and Fertilizer, and the improvement work in saline land at short notice (about 2-3) adopts the complex art including physics, chemistry, biology, agronomic technique and river construction fundamentally to administer and improvement saline land.
The formation in saline land is to be determined by natural conditions comprehensive function results such as local weather, geology, landform, vegetation and underground water situations.Soil is the important natural resourcess of the mankind, and in the middle of agricultural, soil, as the carrier of plant growth, directly affects the growth of crop.In saline land, the most key factor is adsorptivity sodium, salt content and the pH value containing in soil.In saline-alkali soil, sodium, salinity and pH value are higher, have destroyed the physical property of soil.Northeast soda alkaline land parent soil material is river lacustrine sediments, cement or aleuritic texture soil, quality poor permeability, hollow billet are strong, for condition has been created in saline and alkaline gathering, and easily make people, the weight such as animals, agricultural machinery falls in ground, has a strong impact on agricultural machinery working.
From above-mentioned, the main contents of soda alkaline land improvement are as follows:
1. reduce soda alkaline land pH value (be preferably down to neutrality or faintly acid PH=6.5 left and right, suitable paddy rice is raw).
2. reduce content (the exchangeability Na in Na ion concentration and soil colloid in the soil solution of salinity, especially Na
+content).
3. improve being adsorbed property Na
+the soil physical properties destroying.
4. anti-accumulation of salt in the surface soil alkali, protection improves achievement and prevents secondary salinization.Alkaline land improving main contents comprise following engineering, first do not plough saline land reclaimed land and make paddy field, comprise entirely, set up and improve paddy field and fill with row's Engineering System, after soaked field washing salinity secondary, implement improvement engineering, laying modifying agent is raked the soil level, and stirs modifying agent and the pulping rice transplanting of further leveling land; From then on, enter rice cropping agronomy engineering, comprise grow seedlings, rice transplanting, water management, fertilizer management, disease pest and weed management, the engineerings such as results.
Summary of the invention
The present invention discloses a kind of magnet mine tailing composite modifying agent and administers improvement soda alkaline land method, object is to shorten improvement time and raises the efficiency, utilize magnet mine tailing composite modifying agent to administer soda alkaline land technology, modifying agent material is easy to get, easy and simple to handle, be beneficial to popular and be convenient to promote the use of technology.
a kind of magnet mine tailing composite modifying agent provided by the invention is administered improvement soda alkaline land method, and technical solution is as follows:
Tourmaline powder is broken into 0.5 ~ 1.0mm powdery to be divided in the porous beanbag connecting on long rope, press the even spreading of 50kg ~ 300kg tourmaline/per hectare on the face of paddy field, keep 1-2cm water layer, field water is fully contacted with tourmaline, 35-36 water cluster is cut into 5-6 water cluster, the dissolving power of water and penetration are strengthened; Draining completely after soaked field 4-5 days, the new water of supplementary irrigation, then steep 4-5 days Drainage of salts, starting to lay by magnet mine tailing, fermentation fertilizer, furfural dregs ratio is pause/hectare of 20-30,15-25,5-10() modifying agent that is mixed; Pour water and harrow a field and pulping, rice transplanting, carries out conventional rice cultivating technique management.
The magnet mine tailing the present invention relates to be nontoxic, without harmful heavy metal, "dead" element, its main chemical compositions is: 60%-80% silica, 3 ~ 5% Al, Ca, Mg, K, Na oxide and 1-1.5% magnet (Fe
3o
4) composition, the nearly half particle of magnet mine tailing is micro-nano.
The tourmaline the present invention relates to, its chemical molecular formula is NaX
3al
6(BO

4.Cut off the effect of water hydrogen bond by tourmaline, by hydrone (35-36 water cluster is cut into 5-6 water cluster), dissolving power and penetration are strengthened, tourmaline also has surface-active effect simultaneously, can increase substantially washing salt effect, and then reach the object that shortens improvement time and raise the efficiency.
The fertilizer the present invention relates to is that conventional pig, ox, sheep and poultry manure fermentation made.
good effect of the present invention is:utilize tourmaline to improve the quick salt reduction of desalinization of soil by flooding or leaching effect, before soda alkaline land rice transplanting, Drainage of salt is to realize fast reducing salinity; In saline-alkali soil, cover magnet mine tailing, can change soil physical properties, make rainwater easily permeate, drip washing table soil salinity, soil texture chap simultaneously, anti-accumulation of salt in the surface soil alkali, anastatic water is difficult for directly arriving ground, and minimizing salinity gathers to earth's surface.Improve the bad physical behaviors such as alkali ground is cold, dead, sticky, reduced salinity rising, chesson, protects alkaline land improving achievement, prevents secondary salinization.
