Description
Technical field
The present invention provides a kind of Magnet mine tailing composite modifying agent to administer improvement soda alkaline land method, belongs to agromelioration technical field.
Background technology
The salinization of soil is a global problem, the most basic reason of the salinization of soil is the problem of soil degradation, thus causing great loss to agricultural production, therefore how improveing and utilizing large-area salt-soda soil 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 an exploration and practice to tilth salinization countermeasure.
Alkaline land improving its essence is the improvement of the ecological environment of Soil and Fertilizer, and the improvement work in salt-soda soil (about 2-3) must adopt the complex art including physics, chemistry, biology, agronomic technique and hydraulic engineering fundamentally to carry out administering to salt-soda soil and improve at short notice.
The formation in salt-soda soil is to be determined by natural conditions comprehensive function results such as local weather, geology, landform, vegetation and subsoil water situations. Soil is the natural resources that the mankind are important, and in the middle of agricultural, soil, as the carrier of plant growth, directly affects the growth of crop. Factor the most key in salt-soda soil is the adsorptivity sodium, salt content and the pH value that contain in soil. In saline-alkali soil, sodium, salinity and pH value are higher, destroy the physical property of soil. Northeast soda alkaline land parent soil material is fluviolacustrine deposit thing, cement or aleuritic texture soil, and quality poor permeability, hollow billet are strong, create condition for saline and alkaline gathering, and easily make the weights such as people, animals, agricultural machinery be trapped in ground, have a strong impact on agricultural machinery working.
View of the foregoing, it will be seen that the main contents of soda alkaline land improvement are as follows:
1. soda alkaline land pH value (being preferably down to neutrality or about faintly acid PH=6.5, suitable Oryza sativa L. is raw) is reduced.
2. content (the commutativity Na in Na ion concentration and soil colloid in the soil liquid of salinity, especially Na is reduced+Content).
3. adsorbed property Na is improved+The soil physical properties destroyed.
4. anti-accumulation of salt in the surface soil alkali, protection improves achievement and prevents secondary salinization. Alkaline land improving main contents include following engineering, first do not plough salt-soda soil clearage and make paddy field, including entirely, set up and improve paddy field and fill row's Engineering System, improvement engineering is implemented after soaked field washing salinity secondary, laying modifying agent is raked the soil level, and stirs modifying agent and pulping rice transplanting of leveling land further; From then on, enter rice cropping agronomy engineering, including nursery, rice transplanting, water management, fertilizer management, the engineerings such as disease pest and weed manages, results.
Summary of the invention
Disclosure one Magnet mine tailing composite modifying agent administers improvement soda alkaline land method, purpose is in that shorten improvement time and improve efficiency, Magnet mine tailing composite modifying agent is utilized to administer soda alkaline land technology, modifying agent material is made to be easy to get, easy and simple to handle, it is beneficial to popular and is easy to promote the use of technology.
A kind of Magnet mine tailing composite modifying agent provided by the invention administers improvement soda alkaline land method, and technical solution is as follows:
Tourmaline powder is broken into 0.5 ~ 1.0mm powdery and is divided in the porous beanbag connected on long rope, uniformly dispense on face, paddy field by 50kg ~ 300kg tourmaline/per hectare, keep 1-2cm water layer, field water and tourmaline is made to be fully contacted, 35-36 water cluster is cut into 5-6 water cluster, makes the dissolving power of water strengthen with penetration; Soaked field is complete draining after 4-5 days, the new water of supplementary irrigation, then steeps 4-5 days Drainage of salts, and starting to lay by Magnet mine tailing, fermentation fertilizer, furfural dregs ratio is that 20-30,15-25,5-10(pause/hectare) modifying agent that is mixed; Pour water and harrow a field and pulping, rice transplanting, carry out the rice cultivating technique management of routine.
The Magnet mine tailing that the present invention relates to be nontoxic, without harmful heavy metal, "dead" element, its main chemical compositions is: 60%-80% silicon dioxide, Al, Ca, Mg, K, Na oxide of 3 ~ 5% and 1-1.5% Magnet (Fe3O4) form, Magnet mine tailing nearly half granule is micro-nano.
The tourmaline that the present invention relates to, its chemical molecular formula is NaX3Al6(BO3)3Si6O18(OH)4. The effect of water hydrogen bond is cut off by tourmaline, by hydrone (35-36 water cluster is cut into 5-6 water cluster), dissolving power is made to strengthen with penetration, tourmaline also has surface-active effect simultaneously, washing salt effect can be increased substantially, and then reach shorten improvement time and put forward high efficiency purpose.
The fertilizer that the present invention relates to is that the pig of routine, cattle, sheep and poultry manure fermentation are made.
The positive effect of the present invention is in that:Utilizing 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 quickly reducing salinity; Covering Magnet mine tailing in saline-alkali soil, thus it is possible to vary soil physical properties, make rainwater readily permeable, drip washing table earth salt is divided, the soil texture is thicker simultaneously, anti-accumulation of salt in the surface soil alkali, and anastatic water not easily directly arrives ground, reduces salinity and gathers to earth's surface. Improve the alkali ground bad physical behavior such as cold, dead, viscous, decrease salinity and rise, chesson, protection alkaline land improving achievement, it is prevented that secondary salinization.
