Abstract

The invention discloses a disease-and-pest preventing fertilizer special for selenium-enriched dendrobium officinale. The disease-and-pest preventing fertilizer is made from tea dregs, rice bran, distillers' grains, cushaw stem, cow dung, fishbone dust, sepiolite, selenium-enriched corncob powder, selenium-enriched yeast, chlorella powder, coal ash, diammonium phosphate, EDTA (ethylene diamine tetraacetic acid) chelated zinc, potassium sulfate, manganese sulfate, sodium selenite, pyrethrum extract, loropetalum chinense leaf extract and fructus cnidii extract. The invention further discloses apreparation method of the disease-and-pest preventing fertilizer special for selenium-enriched dendrobium officinale. The prepared fertilizer special for selenium-enriched dendrobium officinale has the advantages that the fertilizer has rich nutritional ingredients, can meet various nutrition needs of the selenium-enriched dendrobium officinale during growth, can effectively prevent and treat softrots, anthracnose, black spots, phenacaspis cockerelli and the like, and is beneficial to yield increase of the selenium-enriched dendrobium officinale.

Description

technical field [0001] The invention relates to the technical field of dendrobium candidum planting, in particular to a selenium-enriched dendrobium candidum special fertilizer for preventing pests and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium is poorly absorbed by humans and animals, and has a high risk of toxicity. Improper use can easily cause selenium poisoning; the latter The former mainly refers to the form of selenium combined with biological organic molecules. For humans and animals, organic selenium has a high absorption rate and low toxicity risk, which is more suitable for the re...
