Description
Technical field
The present invention relates to a kind of polynary plant liquid compound manure and preparation method thereof, more particularly, relate to a kind of polynary plant nutrition liquid that is rich in light rare earths and preparation method thereof
Background technology
The trend of current chemical fertilizer development is mass production and uses compound manure.Its advantage be various nutritive element prescriptions rationally, comprehensively use, thereby reduced and used formality, the saving of labor, save time.Solid-state composite fertilizer is easy to stop up fertilizer machinery, plant recovery of nutrient is low and absorbed slow shortcoming by crop in order to overcome, and it is very fast that liquid in recent years composite fertilizer (foliage fertilizer) develops.Along with the growth of vegetables, fruit, flowers, medicinal material and characteristic farm crop demand and the development of greenhouse gardening and cultivation technique without soil, the quality of foliage fertilizer and demand have all been proposed to upgrade higher requirement.Disclosed recently a series of patents show that rare earth element is added to has become a kind of new measure (Chinese invention patent: CN1147494A:CN1186791A:CN1237567A that improves foliage fertilizer quality and fertilizer efficiency in the liquid composite fertilizer; CN1220827A; CN1279229A; CN1295054A) etc.
Research and facts have proved that rare earth element (particularly light rare earths such as lanthanum, cerium) (as plant-growth regulator) can promote absorption and the utilization of crop to nutritive elements such as nitrogen, phosphorus, potassium; Promote seed to take root, germinate, chlorophyll increase, the photosynthesis of plant leaf are strengthened, help the accumulation of dry-matter; Strengthen disease-resistant, drought resisting, waterlogging and the contamination resistance of crop; Finally reach raising output, improve the effect of quality, premature ripening and minimizing disease.But what reach above-mentioned effect and effect key and be rare earth exists form and working concentration and usage quantity.Form must be a soluble state, preferably the organic chelated attitude that is easily absorbed by crop; Consumption is with R
