Problems solved by technology

The foliar fertilizer of the present invention is a mixture of bamboo vinegar and chitosan, which can directly increase the concentration of sugar for crops after being applied to the plant foliage, promote the growth of crop root systems, induce crops to produce various disease-resistant substances, and have a good effect on fungi. 1. Bacteria have extremely strong inhibitory, passivation and preventive effects, but the foliar fertilizer of the present invention cannot be applied to plants lacking trace elements, and can only be used as a common fertilizer, and the pertinence is insufficient

Abstract

The invention discloses a selenium-rich leaf fertilizer and a preparation method thereof, relating to the field of leaf fertilizers. The selenium-rich leaf fertilizer contains the following raw materials in parts by weight: 15-20 parts of potassium fulvate, 15-20 parts of sodium metasilicate, 8-15 parts of boric acid, 0.7-1.2 parts of selenium dioxide, 0.7-1.2 parts of sodium selenite, 5-10 partsof manganese sulfate, 3-8 parts of zinc sulfate, 10-16 parts of ammonium molybdate, 0.4-0.8 part of anion powder, 30-40 parts of potassium dihydrogen phosphate, 0.7-1.2 parts of a surfactant, 1.5-2.5parts of fish meal and 0.2-0.6 part of a functional aid. By virtue of synergetic cooperation effect of the components, important components such as silicon, selenium, molybdenum, manganese, boron, amino acid and auxin required by crops are effectively supplemented, the growth of the crops is promoted, and the stress resistance of the crops is improved.

Description

technical field [0001] The invention relates to the field of foliage fertilizer, in particular to a selenium element foliage fertilizer and a preparation method thereof. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. [0003] Chinese patent CN103396253B discloses a foliar fertilizer with broad-spectrum effect, which is composed of the following parts by weight: 10-19.5 parts of sodium nitrophenolate, 300-400 parts of sodium octaborate tetrahydrate, and 6-7.5 parts of sodium naphthalene acetate Or 4-4.5 parts of indole butyric acid. The broad-spectrum foliar fertilizer provided by the invention can quickly penetrate into the plant body after being in contact with plants, promote the primary flow of cells, improve cell viability, have two-way regulation, promote healthy plant growth, and not only increase the total The synthesis of nutrients...
