Abstract

The invention discloses a selenium enrichment soil nutrient and a preparation method of the nutrient, and a cultivation method of Huangshan tribute chrysanthemum. The nutrient comprises the following components in parts by weight: 100 parts of attapulgite clay, 0.04-0.06 part of sodium selenite and 10-20 parts of zinc sulfate; the preparation method comprises the following steps of: dissolving, spraying and dewatering. The selenium enrichment soil nutrient disclosed by the invention is uniformly distributed in soil, not easy to run off and long in fertilizer efficiency period, and can be sufficiently absorbed by crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a selenium-enriched soil nutrient and a preparation method thereof, and a cultivation method of Huangshan tribute chrysanthemum. Background technique [0002] Selenium is an essential mineral nutrient for the human body, which cannot be synthesized in the human body. The total selenium content of the human body is 6-20mg. Selenium is distributed throughout various tissues, organs and body fluids, with the highest concentration in the kidney, which is very important for improving immunity and preventing cancer. [0003] my country is a big selenium-deficient country, and about 700 million people live in low-selenium areas. Scientists measured the selenium content of soil samples from 1,094 counties and cities in my country (accounting for about half of the country), and the results showed that only 1 / 3 of the counties reached the internationally announ...
