The product can be applied directly, also can be used together with chemical fertilizer (in-situ preparation for usage).
Description
Technical field
The present invention relates to a kind of production method of soil conditioner, especially relate to a kind of method of producing soil conditioner with magnesium ore and shell.
Background technology
Chemical fertilizer is the grain of crop (grain).China has consumed the chemical fertilizer of Gross World Product 32%, unit surface fertilizer application amount is more than 3 times of world average level, with excessive fertilization and the fertile consequent of unreasonable use be that utilization rate of fertilizer is low, soil fertility declines, and soil acidification, causes Soil structure situation variation, middle Trace Element Imbalance in soil, the consequences such as environmental pollution is serious, finally cause very big harm to farm crop, cause crop products production declining and quality of agricultural product to reduce.
Many negative impacts that soil acidification brings: the 1) decomposition of soil organic matter, organic humify, the mineralising of nitrogen, all controlled by microbial activities, and the suitable pH value of microbial activities is 6.0 ~ 8.0.PH value is down to 6 when following, and microorganism active declines, and organic matter decomposition is slow.2) acid-basicity of soil is very large to the availability influence of phosphatic form and phosphorus.PH value was at 6.5 ~ 7.0 o'clock, and phosphorus is combined with calcium and is generated mono-calcium phosphate or Si Liaodengji dicalcium phosphate feed grade, and phosphorus is H
2p0
4 -and HP0
4 2-form, crop can absorb; When pH<5.5, phosphate radical is combined with iron, aluminium and is formed tertiary iron phosphate, aluminum phosphate is fixed, and loses fertilizer efficiency.3) due to alkali exchange interaction, the K on acid soil colloid
+, Ca
2+, Mg
2+by H
+replace, enter the soil solution and run off, cause potassium, calcium, magnesium nutrition element to lack.4) meanwhile, soil acidification activation heavy metal element, as: cadmium, mercury, lead, chromium, aluminium etc., cause quality of agricultural product to decline, make food safety have hidden danger.
Magnesium is the important element of growth and development of plants, is chlorophyllous central element, at Development of Chloroplasts with in carrying out function course, plays a significant role.Magnesium participates in assembling and the basal granule buttress of thylakoid membrane and folds, and to maintaining chloroplast structure, has critical function.Magnesium can promote photosynthetic carbon assimilation.Magnesium or the activator of many enzymes, nearly all Starch phosphorylase and kinases all need magnesium ion activation.Magnesium can stabilized DNA and RNA, for transcribing with translation process, plays an important role.Therefore, magnesium, for plant vital activity particularly important, has vital role for improving crop yield and forest reserves.But, in the last few years along with industrial development, many regional acid depositions increase gradually, magnesium is soluble loss in acid soil, and in the place of using in a large number nitrogen, phosphorus, potassium fertilizer, excessive potassium absorbs magnesium to plant restraining effect, cause plant physiology magnesium deficiency, especially subtropical zone high temperature and rainy, the aggravation increasingly that wanes that soil magnesium attainment is divided, has a strong impact on agriculture production.In Europe, some regional forests even occur that Mg nutrient is not enough and cause the phenomenon of forest decline.Some pasture occurs that because magnesium element in herbage is not enough cattle and sheep blood magnesium is not enough, and the spasm symptom that causes twitching, seriously restricts animal husbandry development.
It is reported, China's soil magnesium deficiency area accounts for 6% of national total cultivated area, and many places have occurred that in plant magnesium deficiency chlorosis, especially facility cultivation, magnesium deficiency phenomenon is even more serious.Especially under acidic conditions, H
+plant is absorbed to magnesium and have restraining effect.
Laizhou, Shandong is the Chinese the third-largest magnesium ore resources ground that distributes, and magnesium ore deposit is activated and processed through calcination activation, can improve effective Mg content and improve pH value, and the magnesium slag after activated activation is processed is applied to soil can Mg supplementation element and have and regulate the effect that improves soil.
Ocean shell contains a large amount of bio-oxidation calcium, contains various active composition, has very high using value, take oyster shells as example explanation.Oyster shells is comprised of organism such as mineral substance and protein-polysaccharides, there is natural porous surface, containing a large amount of 2 ~ 10 um micropores, there is stronger adsorptive power, it is the ideal carrier that object adheres to, its bio-oxidation calcium contents, 38% ~ 52%, also has the various trace elements such as sodium, barium, copper, iron, magnesium, manganese, nickel, strontium, through roasting pH, can improve more than 3.
