Description
Technical field
The present invention relates to technical field of fertilizers, relate to a kind of have suppress soil acidification and acid soil improvement effect and the alkaline fertilizer of pH value > 7.0.
Background technology
The nutrient that plant needs comprises macroelement (as nitrogen, phosphorus, potassium), moderate-element (as calcium, magnesium, sulphur), trace element (as boron, zinc, iron, copper, manganese, molybdenum, chlorine) and beneficial element (as silicon, selenium, chromium etc.), except a small amount of straight fertilizer, major part nutrient element exists often in a salt form, and these salts are exactly the chemical fertilizer be referred to as.
Chemical fertilizer inherently has acid-basicity, and different metal ions combines from different acid groups, because the strongly-acid of the strong basicity of metal ion and weakly alkaline and acid group, slightly acidic various combination, chemical fertilizer is dissolved in water and presents certain acid-basicity reaction.Every be dissolved in water present acid-reaction be acidic fertilizier, as ammonium sulfate, ammonium chloride, monoammonium phosphate, potassium primary phosphate, calcium superphosphate etc.Degree due to synthesis or conversion in fertilizer process is different, also can bring the unreacted Acid constituents of part into, this can increase the weight of the acid degree of fertilizer, as potassium sulfate, Repone K, magnesium sulfate etc. that chemical method is produced, because containing free acid in significantly acid.Every be dissolved in water present alkali reaction be alkaline fertilizer, as diammonium phosphate, dipotassium hydrogen phosphate etc.These can be referred to as physics acid-basicity.
The demand of plant to Different Nutrients is different, therefore, the negatively charged ion of the chemical fertilizer be manured into soil after plant absorption in soil is different with positively charged ion residual quantity, when positively charged ion residual quantity presents alkalescence gradually significantly more than soil during anionic residue allowance, when anionic residue allowance presents acidity gradually significantly more than soil during positively charged ion residual quantity, the physiological alkalinity of Here it is fertilizer and physiological acidity.If ammonium sulfate, ammonium chloride, monoammonium phosphate, potassium primary phosphate etc. are physiological acidic fertilizer, SODIUMNITRATE, nitrocalcite, calcium ammonium nitrate, magnesium nitrate etc. are physiological alkaline fertilizer.It is physiological neutral fertilizer that zwitterion absorbs fertilizer in a basic balance, as saltpetre, ammonium nitrate, urea etc.
Plant has oneself suitable soil acidity or alkalinity scope, except indivedual plant alkali resistance, acid resistance are stronger, the pH value range that majority of plant is suitable for is between 5.5 ~ 7.5, wherein maximum between 6.0 ~ 7.0 of optimum pH scope, and various nutritive element validity in this pH value range is better, the plantation of optimum crop.A large amount of fertilizer has been dissolved in the liquid phase of soil, therefore different soil can present different potential of hydrogen, and soil peracid or excessively alkali all can affect the growth of root system of plant, cause the efficient decline of Different Nutrients, ecotope in spoiled soil, causes obstacle to the growth of crop.Mass data proves, excessively uses chemical fertilizer, especially uneven fertilising, and in havoc soil, the balance of nutrient, can accelerate the acidizing degree of soil.The greenhouse of year after year planting, booth, orchard, vegetable soil be obviously acidifying, cause soil compaction, have a strong impact on the root growth of crop, plant growing way weakens, and resistance against diseases reduces, middle and trace element utilization ratio declines, a large amount of nutrient can not be absorbed, and occurs nutritive deficiency, creates obstacle to the growth of crop, limit the raising of crop yield and quality, seriously constrain the development of modern agriculture.
In February, 2010, the U.S.'s " science " magazine ran: early stage so far from the eighties in last century, almost all have dropped 0.13 ~ 0.80 in the pH value of all soil types of China's discovery, and the continuous acidifying of soil also has the trend of development.China Agricultural University professor Zhang Fusuo thinks, this large-scale pH decreased, needs the time in hundreds of thousands of year usually.That is, due to the impact of the unreasonable activity in production of the mankind, greatly accelerate China's soil acidification, cause great harm will to ecotope and human survival.
The acidifying of China's soil mainly occurs in southern acid soil, particularly red, yellow earth.Have report display, the area of China's acid soil is about 200,000 km2, accounts for about 21% of national total area.These acid soil major parts pH value <5.5, wherein more pH value <5.0, even pH value is low to moderate 4.5.These soil are under irrational Land_use change, cultivation management, and acidizing degree is day by day serious, is becoming agriculture production obstruction factor.Current National soil acidity or alkalinity (pH value) 30 annual have dropped 0.6 unit, and acid cultivated area (pH value <5.5), from 7% before 30 years, rises to current 21%.The ratio of south 14 provinces (district, city) soil pH value <6.5 expands 65% to by 52% before 30 years, pH value <5.5 expands 40% to by 20%, and pH value <4.5 expands 4% to by 1%.The arable soil ratio of the ground pH<4.5 such as Guangdong, Guangxi, Sichuan that acidifying is the most serious is respectively 13%, 7%, 4%.The soil (0 ~ 20cm level) of In Yujiang County, jiangxi Province Red Sandstone parent material development, measured through 1980, wild grass ground pH value 4.84, low yield paddy field pH value 5.90; And this sampling spot sampling and measuring that coexists for 1996, wild grass ground pH value is 4.67, have dropped 0.17, and low yield paddy field pH value is 4.89, have dropped 1.01.
In recent years, the report about the nonacid soil acidification of northern China also increases gradually.According to investigations, there is acidifying in various degree in Area in Yantai Region apple orchard soil, soil pH value≤5.5 proportion, is arranged as in order: Zhaoyuan 32.03%, Peng Lai 29.88%, Qixia 27.7%, Longkou 15.73%, be starkly lower than the pH value of 20th century overall survey of soil eighties.
" Chinese agricultural technology spread " is reported, the cultivated area 2,285 ten thousand mu of pH value less than 4.5 is found out in the whole nation, and there are Shandong Province, Guangdong Province, Sichuan Province, Jiangxi Province, Chongqing City, Fujian Province, Hubei Province, Hunan Province, Guangxi Zhuang Autonomous Region, Anhui Province in the province of first 10.The area 2.26 hundred million mu of pH value less than 5.5 is found out in the whole nation, and the province of first 10 is followed successively by Hunan Province, Jiangxi Province, Heilongjiang Province, Anhui Province, Guangdong Province, Sichuan Province, Hubei Province, Chongqing City, Fujian Province, Shandong Province.The whole nation finds out that front 10 provinces of pH value less than 6.5 are followed successively by Heilongjiang Province, Hunan Province, Jiangxi Province, Anhui Province, Jilin Province, Hubei Province, Sichuan Province, Liaoning Province, Inner Mongolia Autonomous Region, Shandong Province.
The harm that soil acidification is produced: soil acidification increases the weight of soil compaction, suppress root system development, cause that nutrient availability declines, soil fertilizer water retention capacity reduces, soil acidification plant growing way weakens disease resistance reduction and increases the weight of agricultural chemicals waste, soil acidification causes most of Nutrient Absorption utilization ratio very low, soil acidification causes crop alimentary bad quality to decline, soil acidification makes soil beneficial microorganism population die down harmful bacteria amount reproduction, and the benign cycle that soil acidification affects nutritive element causes the agriculture underproduction.
The biological activity of Soil Microorganism is relevant with the acid-basicity of soil, and as soil bacteria and actinomycetes are suitable for neutral and slight alkalinity environment, in strongly acidic soil, fungi is then preponderated.Under the environment of soil acidification, Plant diseases more than 80% is caused by fungi, and this is also the reason that in agricultural chemicals, sterilant accounts for the agricultural chemicals total amount overwhelming majority.
At present, domestic and international fertilizer enterprise is be main raw material with urea (pH value 7.0), ammonium sulfate (pH value 5.5), ammonium chloride (pH value 5.0), monoammonium phosphate (pH value 4.5), potassium primary phosphate (pH value 4.7), saltpetre (pH value 7.0), potassium sulfate (Mannheim proeess pH value 2.5 ~ 3.5), Repone K (pH value 7.0) etc. substantially, therefore, the pH value of sold fertilizer is all less than 7.0 in the market, and its pH value mostly all belongs to acidic fertilizier between 3.0 ~ 6.5.Acid group residual after the acidity of these fertilizer (or raw material) itself or cationic absorbent is all the root causing soil acidification.
Acidic fertilizier optimum is used in alkaline soils, the preparation method of strong-acidic water-soluble fertilizer special for alkaline soil disclosed in CN102503719B, is exactly the strongly-acid fertilizer of pH value between 1.5 ~ 3.0.
These acidic fertiliziers employ decades in China, have made outstanding contributions to the development of agricultural, however China's agricultural development initial stage due to fertilizer amount fewer, the residual quantity in soil is not high yet, does not also cause the obstacle to plant growth.But, along with the progress of agricultural planting, greatly developing of cash crop, fertilizer amount is increasing, in soil nutrient, the residual quantity of acid group gets more and more, especially the cultivating soil of the high-grade cash crop such as greenhouse, booth, orchard, vegetable garden, soil acidification and salt accumulation are very serious, cause the serious degradation of soil.The soil acidification area of China cash crop growing area reaches more than 70% according to statistics, and Shouguang, Shandong vegetables flake old greenhouse for years, booth have arrived the situation having to all change soil.
Theory, minimum nutrient theory, theoretical, the of equal importance theory of diminishing returns, irreplaceable theory, factor integration intreractive theory is given back according to nutrient, we can pass through preferred feedstock kind completely, when carrying out formulating of recipe, when meeting crop needs, to reduce the residual volume of negatively charged ion as far as possible for principle, by optimum combination and production control technique, adopt the methods such as balance formula fertilising, under the megatrend of soil acidification, in order to suppress and improve the alkaline fertilizer that soil acidification produces the use of suitable non-alkaline soil.
At present, the specialized factory of alkaline fertilizer is not also produced.In sum, in order to suppress soil acidification, improvement soil regime, promote the sustainable development of rural economy to replace acidic fertilizier in the urgent need to alkaline fertilizer at present, to meet the demand of acidified soil.
