A kind of amino acid liquid fertilizer and its preparation method

Abstract

The invention discloses an amino acid liquid fertilizer and a preparation method thereof. The amino acid liquid fertilizer comprises amino acid, zinc sulfate heptahydrate, boracic acid, molybdate tetrahydrate, magnesium sulphate heptahydrate, water and the like. The preparation method comprises the following steps: A, respectively dissolving chemically pure reagents of the zinc sulfate heptahydrate, the boracic acid, the molybdate tetrahydrate and the magnesium sulphate heptahydrate by using a suitable amount of water; B, mixing the mixed solution obtained in the step A with amino acid solution, and finally fixing the volume to a standard volume, namely the original liquid of trace element-containing amino acid liquid fertilizer. The amino acid liquid fertilizer is reasonable in formula and convenient to use; the problems that the growing trend is weak, the quality is reduced and the like caused by the fact that the fertilizer aiming at economic crops has unreasonable element proportion and intermediate and trace element deficiency are solved. Compared with the fruiting quantity and the final yield obtained by spraying clean water, the fruiting quantity and the final yield obtained by spraying the amino acid fertilizer are respectively increased by 8.8 percent and 10.3 percent; the content of chlorophyll a in leaves is improved; the pepper yield is improved by 12.1 percent; the tomato yield is improved by 7.8 percent; the content of vitamin C and the content of soluble protein in the tomato are increased.

Description

technical field [0001] The invention relates to a fertilizer, more specifically to an amino acid liquid fertilizer, and also to a preparation method of the amino acid liquid fertilizer, which is suitable for vegetables and fruit trees. Background technique [0002] As vegetables and fruits are getting more and more attention in the daily healthy diet, people have put forward higher requirements for their nutritional value. In addition to being rich in dietary fiber such as water, carbohydrates, and vitamins, vegetables and fruits can also provide protein and some trace elements necessary for the human body. [0003] Amino acid liquid fertilizer comes from medical waste amino acid human injection. Because the time is too long, it is not suitable for human injection, but it can be used in the production of agricultural fertilizers. It is not only an effective way to recycle industrial waste liquid, but also avoids the pollution of the environment caused by waste liquid disc...
