Abstract
The invention discloses a fertilizer additive, a fertilizer composite containing the additive and application of the fertilizer composite and particularly relates to a water soluble fertilizer additive, a water soluble fertilizer composite containing the water soluble fertilizer additive and application of the water soluble fertilizer composite. The water soluble fertilizer additive comprises, by weight, 10 parts of urea phosphate, 1-2 parts of guar gum, 0.5-1 part of polyacrylamide, 0.5-1 part of potassium polyacrylate and 0.1-0.5 part of sodium of polyaspartic Acid. The water soluble fertilizer additive can effectively reduce the frequency of the phenomenon that a water dropper is blocked when water soluble fertilizer containing the water soluble fertilizer additive is applied to fertigation, and reduce the probability of the phenomenon that crops do not absorb the obtained water soluble fertilizer. Meanwhile, the water soluble fertilizer additive can effectively solve the problem that the use ratio of phosphorus fertilizer in the water soluble fertilizer is low.
Description
Technical field
The Ru 2006101161 that the present invention relates to a kind of fertilizer additive, contains this additive and application thereof, be specifically related to a kind of water-soluble fertilizer additive used while can be applicable to the farm crop fertigation, water-soluble fertilizer composition and the application thereof that contains this additive.
Background technology
Irrigating with fertilising is that farm crop are provided desired nutritional and moisture and promote the artificial breeding technique of plant growth.Irrigation can be divided into flood irrigation, sprinkling irrigation, drip irrigation, infiltrating irrigation etc.; Wherein, drip irrigation is to utilize pipeline that water is delivered to the mode that crop root carries out localized irrigation by the water dropper of diameter 10mm or a hole, and it is the most effective Water Saving Irrigation Mode in current drought and water shortage area, and water use efficiency can reach more than 95%.Fertigation is by the fertilizer in water soluble, and great majority are inorganic elements fertilizer, utilizes the effect of drip irrigation to reach simultaneously the purpose to crop fertilization.By fertigation, on the one hand due to solvable fertilizer along with dripping irrigation water directly applies the crop root compact district, drip irrigation is to infiltrate crop root zone with the low discharge form of dripping on the other hand, wastes lessly, the fertilizer efficiency utilization ratio can reach more than 70%.
The problem be prone in fertigation at present mainly contains following a few part:
One, in fertigation owing to containing fertilizer, medicament or microbe composition etc. in aqueous solvent; Simultaneously, the aqueous solution speed that flows is relatively slow, therefore usually can cause emitter clogging because of the factor such as biological, chemistry or physics.The crystallization that the silt that the aqueous solution exists, aqueous temperature reduction produce etc. is the more common physical factor that causes emitter clogging; Microorganism in the aqueous solution etc. is the more common biotic factor that causes emitter clogging; The chemical precipitates that each chemical composition reaction in the aqueous solution produces is the more common chemical factor that causes emitter clogging.
Two, in fertigation, liquid manure concentrates on less zone, and the fertilising meeting of long-term high density causes certain " detesting fertile disease " to crop root.
Three, in addition, as problem comparatively general in agricultural irrigation, phosphate fertilizer is easily by soil fixing, thereby is difficult to reach the purpose of effective supply crop root, and therefore, phosphate fertilizer often needs excess to use, and utilization rate of fertilizer is lower.
