Problems solved by technology

Liquid inorganic compound fertilizer contains two or three kinds of nutrients in N, P and K, such as ammonium phosphate, ammonium urea phosphate, ammonium nitrate phosphate, potassium ammonium phosphate, etc., and they can add medium nutrients (Ca, Mg, S) and trace elements (Zn, B, Ca, Fe, Mn, Mo), this fertilizer is mainly used for the fertilization of flower plants, the cost is high, and it is difficult to promote large-scale plants
[0003] Most of the various liquid organic fertilizers currently available on the market belong to the humic acid or amino acid series. Since this kind of fertilizer only belongs to a single humic acid liquid fertilizer and does not contain the inorganic salts needed by plants, it cannot fundamentally solve the problem. For the problem of plant growth, lodging and disease resistance are not as good as silicon-containing liquid fertilizers; a single silicon fertilizer cannot solve the problem of plant protein synthesis and plant photosynthesis efficiency.

Abstract

The invention relates to the field of fertilizer and particularly relates to liquid fertilizer containing nano micro-silicon powder suspended matters. The liquid fertilizer is prepared from the following components: active nano micro-silicon powder, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, zinc fertilizer, ferrous sulfate, calcium fertilizer, magnesium sulfate and water. The liquid fertilizer containing the nano micro-silicon powder suspended matters is green, ecological and pollution-free silicon-containing liquid fertilizer which realizes waste utilization; the liquid fertilizer is low in cost, abundant in nutrient content, can be used as a soil conditioning agent for improving soil and has the effects of preventing diseases, preventing insects and reducing toxin; the liquid fertilizer is absorbed better by plants, the lodging tolerance of crops can be effectively improved and the yield of the crops is improved; and the quality of the crops, and fruits and vegetables can be effectively improved, and the effects of increasing yield and income are realized.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a liquid fertilizer containing suspended nano-silica powder. Background technique [0002] Liquid fertilizers have been developed for 200 years. There are many varieties, which can be roughly divided into two categories: liquid inorganic nitrogen fertilizer and liquid inorganic compound fertilizer. Liquid inorganic nitrogen fertilizers include ammonium, nitrate and amide nitrogen, such as liquid ammonia, ammonia water, ammonium nitrate and ammonia, urea and ammonia, etc. Liquid inorganic compound fertilizer contains two or three kinds of nutrients in N, P and K, such as ammonium phosphate, ammonium urea phosphate, ammonium nitrate phosphate, potassium ammonium phosphate, etc., and they can add medium nutrients (Ca, Mg, S) and trace elements (Zn, B, Ca, Fe, Mn, Mo), this fertilizer is mainly used for the fertilization of flower plants, the cost is high, and it is difficult to promote ...
