Background technology
Acid soil is the class soil that has more production barrier factors, because its level of the productive forces is lower, is considered to can be used for reluctantly the land resources of agriculture production.Existing 1.37 hundred million hm of China
2in crop land, acid soil accounts for 1/3rd, and majority yields poorly, and seriously hampers the development of China's agricultural.The outstanding production problem of acid soil is plant undergrowth, its essence be cause sour positively charged ion too much, plant essential nutrient element lacks.The traditional method of rescuing acid soil in agricultural is liming.Its Main Function is activity, the raising soil degree of base saturation that reduces soil acidity, controls objectionable impurities and changes soil colloid variable charge quantity etc.The general lime material improvement acidified soil that uses in agriculture production at present, the change of liming to soil pH value and the increase of calcium ion activity have certain effect, but because a large amount of alkaline matters are put into, series of physical, chemistry and Biochemical processes in soil are caused to larger change, thereby affect activity and the balance of various ions in soil, and then directly or indirectly affect the plant availability of these elements.Cause soil compaction, water-permeable to decline, reduce plant and absorb phosphorus, trace element etc.
U.S.'s " science " magazine was once reported, from the eighties in last century so far in early days, the potential of hydrogen of all soil types of almost finding in China 0.1 to 0.8 unit that all declined, this scale soil acidification " needs the time in hundreds of thousands of year " conventionally under field conditions (factors).Agriculture production starts to use more and more chemical fertilizer in order to obtain higher output, is the major reason that causes current Farmland Soil Acidification.
Some chemical fertilizer is dissociated into positively charged ion and negatively charged ion after executing in soil, because Crop positively charged ion is wherein more than negatively charged ion, make to remain in acid ion in soil more, thereby the acidity of soil (or soil solution) is improved, this by making the fertilizer that soil acidity improves just be physiological acidic fertilizer after Crop nutrient, at present, China's chemical nitrogen fertilizer is with urea, ammonium nitrogen; Phosphate fertilizer is with calcium superphosphate, monoammonium phosphate, diammonium phosphate; Potash fertilizer is taking potassium sulfate, Repone K as main, and these fertilizer belong to physiological acidic fertilizer mostly.As ammonium sulfate, Crop NH wherein
4 +more than SO
4 2-, remain in the SO in soil
4 2-absorb with crop replacement the H discharging
+(or dissociation H out
+) be combined into sulfuric acid and make soil acidity improve.So sulphur ammonium, ammonium chloride etc. are all physiological acidic fertilizers.As containing more free sulfuric acid because of it, calcium superphosphate is acid, and for example Repone K, potassium is the necessary nutritive element of plant, is absorbed by plants, and for example ammonium chloride, ammonium ion is weakly alkaline ion, be absorbed by plants, because chlorion is that strong acid radical ion causes acidifying, and for example organic fertilizer, because organic matter can produce a large amount of organic acid in the process of decomposing mineralizing, institute is so that the acidity raising of soil (or soil solution).
On July 3rd, 2013 publication number 103183572A patent, for the fertilizer of acidified soil.Adopt the slow-release fertilizer such as fused(calcium magnesium)phosphate or silico-calcium potash fertilizer, its poorly water-soluble, cannot be used for irrigating facility fertilising, and nutrient quick-acting is low, and fertilizer efficiency is slow.And in product, contain phosphoric, its easily with product in calcium be combined, reduce the effect of product conditioning soil pH, reduction fertilizer validity.
Disclose patent CN102268389 on December 07th, 2011, publication number 102217476A nitrate plant is at application and the restorative procedure repaired in acidified soil.Only limit to be applied to happiness nitre crop, and only rely on crop root to discharge more hydroxyl sweetening of the soil acidity, less on soil pH value impact, root system Soil Surrounding pH is affected by Soil Surrounding can the most again to transfer acidity to.
