Description
Technical field
The present invention relates to a kind of soil improvement agent, particularly relate to a kind of acid soil improvement liquid composite fertilizer, belong to agricultural production.
Background technology
Acid soil refers to the soil of pH value below 7, comprises the great soil groups such as latosol, red earth, red soil, yellow earth and dry red soil.This kind of soil is except the H in soil
+to the obstacle of growth and development of plants, also reduce the obstacles such as the disappearance of particularly medium trace element with the loss of the manganese poisoning under aluminium toxicity, flooding condition, plant nutrient and validity.
Soil acidification is one of subject matter of restriction China agricultural sustainable development, and China's soil acidification problem is very serious, nearly 200,000,000 hm of all kinds of acidified soil area
2.In recent years, along with industrial development acid rain depositions constantly increases, and a large amount of uses of particularly ammonium fertilizer abused by chemical fertilizer, farm crop are gathered in the crops continuously and remove soil neutral and alkali material etc. and cause soil acidification to aggravate further.The a large amount of leaching loss of nutritive element such as Ca, Mg, P in soil can be caused after soil acidification; And heavy metal in soil activity can increase greatly, acid soil heavy metallic poison is the principal element suppressing plant growth and cause crop failure.
Existing improvement acid soil soil conditioner used is divided into two large classes: lime and alkaline industrial residue.Though the former have very strong in and function, but if excessive or use inequality, local calcification can be caused, damage soil microorganisms, affect Soil structure and the demand of crop to secondary and micro-element fertilizers can not be met simultaneously; In the latter and insufficiency of function, though can supply medium trace element usually have heavy metal and the impurity harmful to soil fertility simultaneously, medium trace element kind is single affects soil nutrient balance.
Silicate in crustal rock is the main source of the mineral nutrition of plant, but the silicate crystal formed by magma Slow cooling of occurring in nature can not directly be absorbed and used by plants, need to become microcrystal or noncrystal through very long geochronic weathering soil-forming process, just have the absorbed activity of energy, the essence that soil lacks medium trace element mineral nutrition lacks the activated mineral nutrient element of tool.Made silicate minerals also needs activation for noncrystal or microcrystal, crop utilization could be supplied as secondary and micro-element fertilizers, therefore need the technological measure of fast activating in manufacturing processed, become water-soluble or solubility in citric acid (weak acid dissolubility) state.
China's heavy metal pollution of soil problem is on the rise, has produced very large threat to the healthy of people.And after the heavy metal of accumulation enters human body by food chain in its body of farm crop, bring potential harm can to human body health.Therefore, a kind of soil redeposition that can solve soil acidification problem is badly in need of, to be applied to agriculture production.
Summary of the invention
The present invention is directed to China's arable land big area acidifying, a kind of biotype liquid composite fertilizer containing single silicic acid NPK is provided, to increase Available Silicon In Soils constituent content, improvement sour soil.
