Problems solved by technology

Studies have shown that Apocynum has a special demand for trace elements that is different from other plants, and general universal micro-fertilizers cannot effectively meet the micro-fertilizer requirements of Apocynum, and there is no specific requirement for Apocynum in existing patents and literature. Special Micro Fertilizer
Apocynum is a perennial herbaceous plant, the insufficient supply of micro-fertilizer will inevitably affect its growth, and then affect its economic value

Abstract

The invention discloses a special micro-fertilizer for apocynum venetum and a preparation method thereof. The micro-fertilizer is prepared from lithium chloride, ethylene diamine tetraacetic acid, citric acid, urea and boric acid. The method comprises the following steps: adding urea to boric acid after adding water to dissolve the urea, stirring to obtain a solution A; then adding lithium chloride to react after adding water to dissolve the ethylene diamine tetraacetic acid, so as to obtain a solution B, and then mixing the solution A with the solution B; adding critic acid to stir evenly, so as to obtain a final product, namely the special micro-fertilizer for the apocynum venetum. The foliage spray effect is 2.25 times of mean total leaf dry weight of a single apocynum venetum plant, and 1.7 times of the mean total leaf area of the single apocynum venetum plant after the product is subjected to foliage spray and root application tests. The root application effect is 1.95 times of mean total leaf dry weight of the single apocynum venetum plant, and 1.94 times of mean total leaf area of the single apocynum venetum plant. The special micro-fertilizer has the characteristics of being strong in pertinence, good in water solubility, easy to be absorbed and utilized by the apocynum venetum, simple and convenient to use, less in dosage amount, stable in performance, long in expiration date, significant in yield increase of apocynum venetum leaves, and good in economic benefits.

Description

technical field [0001] The invention relates to a special micro-fertilizer for apocynum and a preparation method thereof. technical background [0002] Apocynum venetum L. is a perennial herbaceous plant of Apocynaceae. It is widely distributed in Northwest my country, North China, East China and Northeast China. Apocynum is a new multi-purpose resource plant with broad development prospects. It is a wild economic crop species with high comprehensive economic value in textile, papermaking and medicine. It has special ecological characteristics such as salt-alkali resistance and drought resistance. Roots, stems, leaves and flowers can be used as medicine, which has the effects of clearing away heat and diuresis, calming the liver, and calming the nerves. It can also be used for the treatment of hypertension, dizziness, palpitations, and insomnia. It was included in the Pharmacopoeia of the People's Republic of China in 1977, 1985 and 1990. Studies have shown that Apocynum h...
