Embodiment 1

[0019] The amino acid foliar fertilizer with a volume of 1 liter, with 400 grams of compound amino acids, 100 grams of ferrous sulfate heptahydrate (FeSO 4 7H 2 O) Dissolve with distilled water respectively at room temperature and mix thoroughly, then add 100 grams of urea, add 50 grams of boric acid, add 10 grams of ascorbic acid, then adjust the pH of the solution to about 5-6 with 0.1% sulfuric acid solution or potassium hydroxide solution After fully stirring and mixing, add 20-50 drops of polysorbate 80 (Tween 80) crop surfactant, and mix thoroughly with distilled water to set it to 1 liter.

Embodiment 2

[0021] The amino acid foliar fertilizer with a volume of 1 liter, 500 grams of compound amino acids, 200 grams of ferrous sulfate heptahydrate (FeSO 4 7H 2 O) Dissolve with distilled water at room temperature and mix thoroughly, then add 200 grams of urea, 100 grams of boric acid, and 50 grams of ascorbic acid, then adjust the pH of the solution to about 5-6 with 0.1% sulfuric acid solution or potassium hydroxide solution After fully stirring and mixing, add 20-50 drops of polysorbate 80 (Tween 80) crop surfactant, and mix thoroughly with distilled water to set it to 1 liter.

Embodiment 3

[0023] Mixing volume is the amino acid foliage fertilizer of 1 liter, with 400 grams of compound amino acids, 200 grams of ferrous sulfate heptahydrate (FeSO 4 7H 2 O) Dissolve with distilled water at room temperature and mix thoroughly, then add 200 grams of urea, 100 grams of boric acid, and 50 grams of ascorbic acid, then adjust the pH of the solution to about 5-6 with 0.1% sulfuric acid solution or potassium hydroxide solution After fully stirring and mixing, add 20-50 drops of polysorbate 80 (Tween 80) crop surfactant, and mix thoroughly with distilled water to set it to 1 liter.

Abstract

The invention provides amino acid leaf fertilizer which is composed of 20-50 percent of compound amino acids, 1-50 percent of nicotinic amide, 10-20 percent of green vitriol, 10-20 percent of urea, 5-10 percent of boric acid, 1-5 percent of ascorbic acid and 1-5 percent of surface active agent, namely polysorbate 80. The pH value is required to be 5.0-6.0. The fertilizer efficiency of the amino acid leaf fertilizer is stable, the fertilizer can obviously strengthen the iron nutrient of paddy rice seeds with different genotypes, averagely, the content of iron in winnowed paddy can be obviously increased by above 15 percent, the content of protein and amino acid in the winnowed paddy rice can be obviously increased, the nutrition and the quality of paddy rice can be enhanced all sidedly, the quality is excellent and the cost is low. Therefore, the amino acid leaf fertilizer can be applied in the highly effective biological strengthening of the iron nutrient in paddy seeds and the remarkable promotion of the nutrition and the quality of paddy rice.

Description

technical field [0001] The invention belongs to the field of foliar fertilizers, and in particular relates to a new type of amino acid foliar fertilizer which can be used for foliar spraying, can effectively bio-enhance the iron nutrition of rice grains, and significantly improve the nutritional quality of rice. technical background [0002] The nutritional imbalance caused by iron deficiency is one of the major nutrition and health problems faced by human beings in the world. Iron deficiency seriously weakens the function of the human immune system and hinders the normal growth and development of the body. According to reports, more than 3 billion people in the world are affected by nutritional deficiencies of iron and zinc, mainly concentrated in developing countries where rice is the staple food. In these countries, 40%-45% of school-age children suffer from anemia, about half of which are caused by iron deficiency. The iron nutritional status of the Chinese population ...
