Embodiment 1

[0026] (1) Preparation of nano-zinc fertilizer: get 2g of corn palm oil nanoemulsion and 1.79g of ZnSO 4 ·7H 2 The distilled water of O, 1L mixes evenly, obtains ZnSO 4 The final concentration is 1g / L, and the nanometer zinc fertilizer with the final concentration of the nano agent is 2g / L.

[0027] (2) Crop seedling cultivation: sow the tomato seeds after germination on the substrate, and cultivate them with distilled water. -2 the s -1 , the incubation temperature is 22±1°C; 12 hours of dark incubation, the incubation temperature is 18±1°C. The substrate for raising seedlings is obtained by mixing perlite, peat and vermiculite in a volume ratio of 1:1:1.

[0028] (3) Application of nano-zinc fertilizer: during tomato flowering period, carry out the spraying of nano-zinc fertilizer, spray once every 5 days, spray three times altogether during the whole flowering period, spray 30L per mu; use the same spraying method with the same volume distilled water as a control; ZnSO...

Abstract

The invention discloses an application of a nano-zinc fertilizer in promoting the accumulation of zinc in crops, wherein the nano-zinc fertilizer is calculated by mass percentage, and the nano-zinc fertilizer consists of a nano-agent with a concentration of 1-4g / L, 0.1- It is prepared by mixing 3g / L zinc fertilizer and water; the micelle particle size of the nanometer zinc fertilizer is 1-100nm. The invention mixes the nano-agent with the zinc fertilizer, promotes the absorption and utilization of the nutrients in the zinc fertilizer by the crops through the nano-small size effect, and improves the utilization efficiency of the fertilizer; and sprays the crops during the flowering period, so that the yield of the crops and the crops can be improved. The zinc content of the food parts is significantly increased, resulting in the production of high-quality zinc-rich agricultural products.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to the application of a nanometer zinc fertilizer in promoting the accumulation of zinc in crops. Background technique [0002] Zinc plays an important role in the metabolism of the human body. There are nearly 200 kinds of enzymes in the body of normal people that require the participation of zinc, and many enzymes require the presence of zinc to exert their maximum activity. Zinc can participate in the formation of genetic material and play an important role in the regulation of gene expression. Zinc is an essential trace element for protein and brain ribonucleic acid synthesis, and is closely related to brain development and brain function maintenance. Zinc participates in maintaining the structure and function of various organs of the body's immune system (such as thymus, spleen, and lymph nodes); zinc deficiency in the human body will cause the atrophy of immune ...
