Background technology
Under Protected Cultivation, due to unreasonable or excessive fertilization, the long-term continuous cropping of crop of the same race, often there will be the phenomenon that crop normal growth is suppressed, be called as continuous cropping obstacle.Cause the reason of continuous cropping obstacle complicated, mainly contain following reason: 1, soil secondary salinization, causes 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, the 2nd, 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 nitrite and the nitrate increase soil solution through nitrification, the total salt concentration of soil is increased, due to the leaching minimizing of soil under facility condition, so cause salt stress to crop.2, soil acidification.In agriculture production, conventionally using nitrogen, potassic fertilizer in Chemical Mixed Fertilizer and be mainly and take vitriol and muriate as main, is all physiological acidic fertilizer, and due to exchange adsorption, root system of plant is absorbing NH
4 +positively charged ion and K
+synchronism soil in discharge a large amount of H
+, the most of SO in fertilizer
4 2-, CL
-in the residual soil of acid ion, cause soil acidification.Soil acidification is the major cause that spoiled soil crumb structure causes soil compaction, pathogenic bacteria population propagation.3, soil compaction, ventilation property are poor, to crop, cause Hypoxia Stress.The root growth of crop, dietetic alimentation physiological activity and root system aerobic repiration activity are closely connected, and soil compaction air permeability declines, 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 host, be conducive to 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, on the one hand for pathogenic soil microorganism provides nutrition, thereby the growth of crop is formed to obstacle.Above phenomenon and the origin cause of formation have shown that continuous cropping obstacle is a kind of complexity, the multifactor result causing, the coercing of the bad change of existing soil physical property, crop rhizosphere environment, and having again rhizosphere biotic factor is the acting in conjunction of microflora.
The measure that the measure great majority of current control continuous cropping obstacle are just taked for a certain of above reason or two kinds, You Yin China is vast in territory, the geographical difference of the natural condition of agriculture production is larger, 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 with improvement soil.Effect is mainly the acidifying problem that solves soil, although lime nitrogen can suppress some soil-borne diseases, it is regions, Ph3 ~ 4 that this method is mainly adapted to south China acid soil, and feasible degree is poor for soils of north China.Liming can not repeatedly be used simultaneously, the bad assurance of usage quantity.2, applying organic manure material.Organic fertilizer has good improvement Soil structure, keeps soil from packing together, the effect of activating soil microorganism, is the technology that a kind of adaptability is extensive.But the control for soil-borne disease does not also reach effect.1), organic fertilizer resource restriction simultaneously it is also subject to the restriction of condition, mainly:, the source of most of facility cultivations region fertilizer is all not enough, reaches the effect of improvement soil, and every mu once at least needs approximately one ton of above exquisite organic fertilizer; 2), existing best buy fertilizer is few.Organic fertilizer must be that the organic fertilizer of handling well through industrialized composting fermentation can reach good Effect of improving soil, uses without the organic fertilizer becoming thoroughly decomposed, and also can bring side effect.Seldom, good Fertilizer application cost is high for best buy organic fertilizer in the market.3, Antagonistic Fungi biological organic fertilizer.Advantage: connect and antibacterially can suppress some pathogenic bacteria.Shortcoming: 1) the bacterium amount in fertilizer does not reach the effect of curing the disease; 2) specificity of Antagonistic Fungi, can not be effective to multiple pathogenic bacteria; 3) connecing antibacterial survival time and timeliness in soil is also 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 soil compaction, salinification, acidifying problem.4, biological pesticide.Effect is not as good as biological organic fertilizer, is mainly that the microorganism that is manured into soil cannot 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 is if monobromomethane is with forbidding, and dazomet has 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 deuterogenesis, and fumigant is in processing in early stage, now drug effect mistake.Do not reach ideal effect.Affect soil beneficial microorganism simultaneously.6, unrestrained water or hot-water cure.Unrestrained water only solves soil secondary salinization problem, and the lasting period is not long, and generally just single cropping effect can.Day water treatment can only be played part disinfection, and anaphase effect is undesirable.And these methods can be used in southern area, at most northern area, can not operate.Therefore, a kind of new method of exigence solves above-mentioned technical problem.
