Slow-release selenium-rich ecological fertilizer for golden camellia and preparation method thereof

Abstract

The invention discloses slow-release selenium-rich ecological fertilizer for golden camellia and a preparation method thereof. The preparation method comprises the following steps: a) dissolving sodium selenite in water to obtain a selenium-rich solution, b) dissolving starch and a dispersing agent into the selenium-rich solution obtained in the step a) to obtain a selenium-rich starch premix solution, c) adding a cross-linking agent into the selenium-enriched starch premixed solution obtained in the step b), and adjusting the pH to 4-7 after reaction to obtain a selenium-enriched starch solution, d) mixing furnace slag, sludge, chinaberry branches and leaves, ginger seedlings, livestock manure, corn straw and rice husks to prepare an organic fertilizer base material, e) dissolving and diluting the BT biopesticide, the activated EM inoculant and the organic fertilizer decomposing inoculant with water to obtain a liquid medicine, and f) adding the selenium-rich starch solution obtainedin the step c) and the liquid medicine obtained in the step e) into the organic fertilizer base material obtained in the step d) in a spraying manner, uniformly turning and mixing, and carrying out anaerobic composting fermentation decomposition for 3-4 days to obtain an ecological fertilizer wet material.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural fertilizer preparation, in particular to a slow-release selenium-enriched ecological fertilizer for golden camellia and a preparation method thereof. 【Background technique】 [0002] Golden camellia belongs to the family Theaceae, and is mainly distributed in the offshoot of Shiwanda Mountain in Guangxi. It is a rare plant with high health care value. Golden camellia has golden petals, thick petals and numerous pistils. The tea soup is as golden yellow as camellia, and the soup color is translucent. Golden camellia has a very high ornamental value and contains a variety of functional ingredients that are important for human health, including flavonoids, saponins, tea polyphenols, catechins, flavonoids, carotenoids, vitamins and amino acids. Natural organic germanium , selenium, molybdenum, vanadium, zinc and other trace elements. Golden camellia contains two main flavonoids, carotenoids an...

Problems solved by technology

Chinese patent application 201711328432.5 is a disease-resistant planting method of camellia camellia, which discloses a disease-resistant planting method of camellia japonica, but the planting site is limited in the method, which is not suitable for large-scale planting, and the disease-resistant liquid fertilizer in the method The preparation is cumbersome and the cost rises

Chinese patent application 201611246295.6 is a rooting agent suitable for cutting seedlings of Camellia japonica green branches, which discloses a method that can effectively promote the growth of Camellia japonica roots and improve the disease resistance of Camellia japonica, but the accuracy of implementation by farmers is insufficient

Chinese patent application 201510983874.8 is a method for preparing a special organic fertilizer for Camellia japonica prepared from citronella and eucalyptus leaves, which discloses the use of citronella and eucalyptus leaf extracts to obtain organic decomposed fertilizers, but the amount of effective extracts is small and the process is complicated

Chinese patent application 201711188939.5, a compound fertilizer for rapid cultivation of Camellia japonica, discloses a compound fertilizer that can quickly improve soil fertility, but there is a risk of destroying soil balance and soil quality pollution

[0005] The demand for selenium-enriched camellia products has increased significantly, but the high-yield, high-quality artificial selenium-enriched camellia planting technology has developed slowly, and the output of only natural-grown camellia camellias is extremely low, and the high added value of trace element selenium There is also the problem of unequal distribution constraints
