Selenium-enriched tomato liquid fertilizer and preparation method thereof

Abstract

The invention discloses a selenium-enriched tomato liquid fertilizer which is prepared from the following raw materials in parts by weight: 5-8 parts of potassium nitrate, 4-6 parts of nostoc sphaeroids kutz, 4-7 parts of funaria hygrometrica, 4-6 parts of potassium chloride, 5-7 parts of ammonium bicarbonate, 4-8 parts of urea, 1-3 parts of klockmannite, 3-5 parts of mulberry fruits, 2-3 parts of ground phosphate rock, 3-5 parts of plant ash, and 6-9 parts of auxiliaries. The tomato liquid fertilizer is uniform and free from impurity and is simple to prepare, the contents of nitrogen, phosphorus and potassium as well as medium trace elements can all meet the growth requirement of tomatoes, due to the adding of klockmannite, mulberry fruit, nostoc sphaeroids kutz and other raw materials, the content of selenium in the fertilizer can be greatly increased, and crushed funaria hygrometrica contains promoters such as kinetin and benzpyrole-3-acetic acid capable of promoting tomatoes to absorb nutrients and grow, and thus the fertilizer is a tomato liquid fertilizer with a remarkable effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium-enriched tomato liquid fertilizer and a preparation method thereof. Background technique [0002] Selenium is an essential trace mineral nutrient for the human body. Since there are no long-term storage organs in the human body, the selenium needed by the body needs to be continuously obtained from the diet. The balance of selenium concentration has an important protective effect on the physiological functions of many organs and tissues Therefore, various selenium-enriched foods are gradually known to people, among which selenium-enriched agricultural products have become the first choice for selenium supplementation due to their naturalness and convenience, but most selenium-enriched crops are planted in soils with high selenium content. Places, geographical restrictions are relatively serious, and most of my country's regions are in selenium-deficient areas, so...

[0002] Selenium is an essential trace mineral nutrient for the human body. Since there are no long-term storage organs in the human body, the selenium needed by the body needs to be continuously obtained from the diet. The balance of selenium concentration has an important protective effect on the physiological functions of many organs and tissues Therefore, various selenium-enriched foods are gradually known to people, among which selenium-enriched agricultural products have become the first choice for selenium supplementation due to their naturalness and convenience, but most selenium-enriched crops are planted in soils with high selenium content. Places, geographical restrictions are relatively serious, and most of my country's regions are in selenium-deficient areas, so it is impossible to obtain selenium-enriched crops economically and economically. For this reason, the inventors have designed selenium-enriched liquid fertilizers, which can effectively solve the above problems. High and easy-to-absorb selenium-enriched liquid fertilizer, plant selenium-enriched agricultural products, and achieve the purpose of supplementing the human body with an appropriate amount of selenium
