Plant leaf fertilizer prepared by natural tea saponin powder

Abstract

The invention discloses a plant leaf fertilizer. The plant leaf fertilizer is prepared by the following components in percentage by weight: 12-15% of tea saponin powder, 45-50% of potassium citrate, 35-40% of industrial zinc sulphate, and 0.8-1.3% of ammonium molybdate. The plant leaf fertilizer disclosed by the invention has the advantages of good solubility and dispersibility, low cost, strong pertinence and good application effect.

Description

(1) Technical field [0001] The invention relates to a plant foliar fertilizer in solid dosage form. (2) Background technology [0002] In the planting industry, the method of fertilization by seed fertilizer is generally used traditionally, but due to the frequent occurrence of some weather conditions different from the expected, it will bring different degrees of loss to production. At the same time, in actual production, the lack of micronutrients in crops is becoming more and more obvious, but the correction method is very complicated. If micronutrients are applied at the same time as seed fertilizer coating or infiltration, many practical problems such as serious separation and uneven mixing will occur. In order to overcome the shortage of seed fertilizers, a variety of foliar fertilizers have been developed and applied in recent years. As top dressing, foliar fertilizers can be used to adjust the time and amount of fertilization according to weather conditions and actua...

AI Technical Summary

Problems solved by technology

[0003] 1) The pertinence is poor, and the ingredients of leaf fertilizer are mostly hormones, humic acid, bacterial fertilizer, amino acid, N, P, K and a mixture of various trace elements, so it is in a state of having everything but not enough. Deficiencies in specific regions and crops present great difficulties

[0004] 2) The effective amount is small. In order to spray more crops per unit volume of liquid fertilizer to reduce costs, the existing foliar fertilizers are concentrated, and only 5-10ml is used per mu. Such a small amount should be distributed to On a crop of 660 square meters, it is difficult for its active ingredients to work

[0005] 3) Due to the formulation of foliar fertilizers, most foliar fertilizers can only be used in liquid form at present, so there are problems such as high storage and transportation costs and poor stability

But the general said that tea saponin is less used for plant foliar fertilizer at present
