Problems solved by technology

[0002] Cotton is an important economic crop with a wide distribution range and a large planting area. It is the most important fiber crop in the world. At the same time, cotton is also a crop that requires more fertilizer. The flowering and boll stage is the period when cotton grows vigorously in its life, and it also requires the most fertilizer. period; but a large amount of chemical fertilizer is a kind of pollution to the environment, and the low utilization rate of soil fertilization is also a waste;

Abstract

The invention relates to a cotton foliar fertilizer which takes water as carrier, and comprises the components by the proportion: 280-350kg / m<3> of urea, 100-150kg / m<3> of calcium superphosphate, 180-220kg / m<3> of potassium dihydrogen phosphate, 45-70kg / m<3> of boric acid, 60-90kg / m<3> of ammonium molybdate, 80-110kg / m<3> of manganese sulfate, 80-110kg / m<3> of zinc sulfate and 100-120kg / m<3> of polyaspartic acid. The cotton foliar fertilizer is prepared by the steps of: putting the urea into water and stirring for 80-120r / min to prepare water solution at the temperature of 30-35 DEG C; adding potassium dihydrogen phosphate, calcium superphosphate, zinc sulfate, manganese sulfate and polyaspartic acid into the water solution to prepare solution a; adding boric acid and ammonium molybdate into boiled water while shaking for dissolving; and adding the obtained solution into the solution a, evenly mixing and adjusting the pH value to be 6.8-7.2.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a cotton leaf fertilizer. Background technique [0002] Cotton is an important economic crop with a wide distribution range and a large planting area. It is the most important fiber crop in the world. At the same time, cotton is also a crop that requires more fertilizer. The flowering and boll stage is the period when cotton grows vigorously in its life, and it also requires the most fertilizer. period; but a large amount of chemical fertilizer is a kind of pollution to the environment, and the low utilization rate of soil fertilization is also a waste; [0003] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts basic functions through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the upper epidermal cells. It can p...
