Technical field
The present invention relates to a kind of the solanaceous vegetables facilities vegetable special nutrient set fertilizer and the application process thereof that are applicable to acidified soil, belong to technical field of fertilizers.
Background technology
Since twentieth century eighties, fast-developing period is stepped in the agriculture production of China, has supported the population of 21% in the world with the soil in the world 8%.But the pattern relying on intensive agriculture production to increase crop yield greatly accelerates the self-souring process of agricultural land soil.China only uses 20 years, and the pH of topsoil soils have dropped 0.13 ~ 0.80 unit, and this needs the centuries even more than one thousand years change procedure that just can complete under field conditions (factors).Soil acidification causes plant growth bad, the underproduction then, easy infection disease and pest, and its essential problem causes sour positively charged ion in soil too much, and essential nutrient element lacks.
In intensive agriculture production, excessive the using of chemical fertilizer causes the topmost reason of soil acidification.Wherein, the nitrification of ammoniacal nitrogen fertilizer, the leaching of nitrate fertilizer, plant to the unbalancedness of nutrition absorption, as to K, Ca, Mg, NH
4etc. cationic absorption higher than to SO
4 2-, Cl
-deng the absorption of negatively charged ion, these all cause the acid ion that fertilizer is remaining in soil many, cause the acidity of the soil solution to improve.And the utilization ratio intensity of Vegetable produce to soil is higher, fertilizers input amount is larger, and therefore the acidification phenomenon of the industrial land of vegetables is more serious.
The method current agriculture production being rescued acid soil has liming, alkaline soil amendment etc.But the input of a large amount of alkaline matter, changes violent to the ecotope in soil and Biochemical processes, easily causes soil compaction, water-permeable reduces, reduce the problems such as plant absorption phosphorus element and trace element, and unstable to the improved effect of acidified soil, and multiple acidizing degree is strengthened.
At present, the prior art of conditioner for acidified soil is a lot.As: Chinese patent document CN104140322A discloses a kind of Semen Caryae Cathayensis soil acidification modifying agent, with parts by weight, consisting of of active principle: calcium cyanamide 100 parts; 15 ~ 30 parts, urea; Ground dolomite 23 ~ 45 parts; 23 ~ 45 parts, calcium oxide; 8 ~ 23 parts, magnesium oxide; Trace element 8 ~ 23 parts.The calcium cyanamide of above-mentioned Optimum ratio, urea and ground dolomite are combined, Semen Caryae Cathayensis soil acidification situation can not only be improved, alleviate the soil fertility obstacle that soil acidification is derivative, control the soil-borne disease because soil acidification causes, also supplement the calcium ion in soil simultaneously, alleviate the calcium ion leaching phenomenon because soil acidification causes.This invention also discloses a kind of preparation method of Semen Caryae Cathayensis soil acidification modifying agent and utilizes described modifying agent to repair the method for Semen Caryae Cathayensis acidified soil.Can rate of fertilizer be greatly reduced by the method for above-mentioned reparation Semen Caryae Cathayensis acidified soil, improve the acidification phenomenon of Semen Caryae Cathayensis soil from root, the reparation of acidified soil can be realized cost-effectively, and significantly improve the output of Semen Caryae Cathayensis.Chinese patent document CN102503728A discloses a kind of modifier for acidized bamboo soil, comprises following component, is respectively by the mass percent of each component: lime nitrogen 45 ~ 55%, biomass carbon 20 ~ 30%, calcium oxide 10 ~ 20%, magnesium oxide 5 ~ 10%, trace element 5 ~ 10%.Modifier for acidized bamboo soil of the present invention is based on lime nitrogen and biomass carbon, be equipped with that medium trace element makes, can repair, administer bamboo shoots soil acidifications, control soil-borne disease insect pest peace weighing apparatus bamboo shoots, to micro-element nutrition demand, have " control acid, control worm, nutrition " triple functions; By adopting modifier for acidized bamboo soil and bamboo shoots special fertilizer compounding application, cutting down the acidifying of bamboo shoots soil from root, having realized the reparation of acidified soil cost-effectively, prevent and treat soil-borne disease, fast lifting soil fertility, improved bamboo shoot output and quality.
But above-mentioned patent document is all attempt to start with solution from soil improvement agent, and have ignored the control to the very middle soil acidification source of agricultural production process.Nitrogen on current Chinese Fertilizer Market, phosphorus, potash fertilizer mostly are physiological acidic fertilizer, although a large amount of alkaline modifying agent of bottom application before crop-planting, using in a large number of later stage physiology acid fertilizer, finally still can not change the process of soil rapid acidification.
