Efficient controlled release fertilizer favorably improving taste and freshness of ivy mosses and preparation method thereof

Abstract

The invention discloses an efficient controlled release fertilizer favorably improving taste and freshness of ivy mosses. The fertilizer comprises the following components in parts by weight: oyster shells, polylactic acid, expanded graphite, thermally activated nano chernozem, pinecones, pomegranate barks, mosses, sugarcane ash, a soil beneficial microbial inoculant, bacitracin zinc, phytase, amino acid, ground calcium ammonium sulfate, boric acid, sodium selenite, chelated iron, potassium fulvate, lysine, a proper amount of hydrogen peroxide, a proper amount of ammonia water, a proper amount of water and the like. The coated controlled release fertilizer is prepared by using the pinecones, the pomegranate barks, the mosses and the sugarcane ash which are matched with nutritional substances through fermentation. The fertilizer is rich in nutrient elements such as fermented small molecular organic matters, calcium, iron, selenium and zinc, is abundant in nutrient and convenient for plants to absorb and utilize, so that the taste and freshness of the ivy mosses can be enhanced; by adopting the coating layer which can supply oxygen and dynamically adjust the porosity, the fertilizer efficiency time is long, organic matter nutrients can be released for a long time, efficient cultivation of the ivy mosses can be realized, and the fertilizer can be widely applied and popularized.

Description

Technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a high-efficiency slow-release fertilizer that helps to improve the taste and freshness of dried moss and a preparation method thereof. Background technique [0002] Dry moss is also known as Gong Cai, Xiang Cai, and Lactuca spp. The color is bright green, the texture is refreshing, and the taste is like jellyfish. The cultivation history of Anhui's rare and precious specialty products can be seen in Qin Dynasty. It is a pure natural green high-grade dehydrated vegetable for more than 2,200 years. During the Qianlong reign of the Qing Dynasty, they paid tribute to the court every year afterwards, so they called it "tribute dishes." Because of the crisp and refreshing sound of its food, it was vividly called "Xiancai" in the 1960s and also known as "Mountain stings". Dried moss contains many kinds of amino acids, sugar, crude protein, calcium, phosphorus, potassium,...
