Description

A kind of soil improvement matrix and preparation method of alleviating soil continuous cropping obstacle

Technical field

The present invention designs a kind of preparation method of soil improvement matrix, relates in particular to a kind of preparation method of soil improvement matrix of releasing facilities cultivating soil continuous cropping obstacle.

Background technology

Under the facility cultivation condition, because unreasonable or excessive fertilization, the long-term continuous cropping of crop of the same race, phenomenon that the crop normal growth is suppressed appears in regular meeting, is called as continuous cropping obstacle.Cause the reason complexity of continuous cropping obstacle, mainly contain following reason: 1, soil secondary salinization, cause salt stress to crop.The origin cause of formation of secondary salinization, the one, long-term, the excessive mineral manure of using causes soil solution excessive concentration, two be to use the fertilizer that do not become thoroughly decomposed especially feces of livestock and poultry be decomposed to form inorganic nutrient, the 3rd, ammonium nitrogen forms the concentration of the nitrite and the nitrate increase soil solution through nitrification, the total salt concentration of soil is increased, because the leaching of soil reduces under the facility condition, so cause salt stress to crop.2, soil acidification.Usually nitrogen, the potassic fertilizer used in the agriculture production in the compound fertilizer mainly are based on vitriol and muriate, all are physiological acidic fertilizers, because exchange absorption, root system of plant is at absorption of N H 4 +Positively charged ion and K +Synchronism soil in discharge a large amount of H +, the most of SO in the fertilizer 4 2-, CL -In the residual soil of acid ion, cause soil acidification.Soil acidification is to destroy the major cause that soil aggregate causes soil compaction, pathogenic bacteria population propagation.3, soil compaction, ventilation property are poor, cause hypoxemia to coerce to crop.Physiological activity such as the root growth of crop, dietetic alimentation and root system aerobic repiration activity are closely connected, and the soil compaction air permeability descends, and directly have influence on the normal growth of crop.4, soil-borne disease is serious.One crop be continuous cropping for a long time for pathogenic bacteria provides the host, help the breeding of pathogenic bacteria; The 2nd, soil acidification provides the condition of existence for pathogenic bacteria.5, root exudates accumulation, cause on the one hand crop from toxic action, provide nutrition for the pathogenic soil microorganism on the one hand, thereby the growth of crop formed obstacle.The above phenomenon and the origin cause of formation have shown that continuous cropping obstacle is a kind of complexity, the multifactor result who causes, the coercing of the bad change of existing soil physical property, crop rhizosphere environment, and it is the acting in conjunction of microflora that the rhizosphere biotic factor is arranged again.

The measure that the measure of present control continuous cropping obstacle great majority are just taked at a certain of above reason or two kinds, the geographical difference of the natural condition of vast in territory because of China again, agriculture production is bigger, therefore existing method one is that effect is undesirable, the 2nd, and technological adaptability is wideless.Existing method introduction and commentary 1, use ammoniacal liquor or ammonium hydrogencarbonate add lime, or use lime nitrogen to improve the soil.Effect mainly is the acidifying problem that solves soil, though lime nitrogen can suppress some soil-borne diseases, it is Ph3 ~ 4 zones that this method mainly is adapted to China's south acid soil, and feasible degree is relatively poor for northern soil.Liming can not repeatedly use the bad assurance of usage quantity simultaneously.2, applying organic manure material.Organic fertilizer has the structure of well improving the soil, keeps soil from packing together, the activating soil action of microorganisms, is the extensive technology of a kind of adaptability.But the control for soil-borne disease does not also reach effect.1), the organic fertilizer resource restriction simultaneously it also is subjected to the restriction of condition, mainly is:, the source of most of facility cultivations zone fertilizer is all not enough, reaches the effect of improving the soil, and every mu once needs about exquisite organic fertilizer more than a ton at least; 2), existing best buy fertilizer is few.Organic fertilizer must be can reach the effect of improving the soil preferably through the organic fertilizer that industrialized composting fermentation is handled well, uses without the organic fertilizer that becomes thoroughly decomposed, and also can bring side effect.In the market the best buy organic fertilizer seldom, good fertilizer use cost height.3, antagonism bacteria organic fertilizer.Advantage: connect and antibioticly can suppress some pathogenic bacteria.Shortcoming: 1) amount of the bacterium in the fertilizer does not reach the effect of curing the disease; 2) antimicrobial specificity short of money can not be effective to multiple pathogenic bacteria; 3) connecing antibiotic survival time and timeliness in soil also is problem; 4) use cost that reaches imitation is difficult to accept; 5) it is few that field experiment is stablized effective product.Can't resolve problems such as soil compaction, salinification, acidifying.4, biological pesticide.Effect is not as good as biological organic fertilizer, mainly is that the microorganism that is manured into soil can't survive for a long time.5, chemical pesticide and soil-fumigating.The effect of chemical pesticide control soil-borne disease is undesirable, and the lasting period is shorter, causes environmental pollution.Fumigant such as monobromomethane etc. are with forbidding, and dazomet etc. have certain effect for nematode, but the lasting period is not long, and the nematode period of disease of some facility cultivation crops that survive the winter is often the deuterogenesis, and fumigant is to handle in early stage, at this moment drug effect mistake.Do not reach ideal effect.Influence the soil beneficial microorganism simultaneously.6, processing such as casual water or hot water.Casual water only solves the soil secondary salinization problem, and the lasting period is not long, and generally just the single cropping effect can.The day water treatment can only be played the part disinfection, and anaphase effect is undesirable.And these methods can be used at southern area, can not operate at most northern area.Therefore, a kind of new method of exigence solves above-mentioned technical problem.
