Problems solved by technology

[0003] The invention provides a foliar fertilizer mixture and a preparation method thereof, aiming at solving the problem that the existing corn foliar fertilizer has low permeability of corn leaves to nutrients, the fertilizer droplets are not easy to penetrate into the leaves, and the water drops of liquid fertilizer are easy to leak from the surface of the leaves. Slipping down, causing loss, low nutrient utilization rate, and short time for the fertilizer solution to be wet on the leaves, especially in windy and high temperature weather, will cause the fertilizer solution to dry quickly on the leaf surface, affecting the absorption of nutrients

preparation example Construction

[0021] The preparation method comprises the following steps:

[0022] Step S101, dissolving the short-chain oligopolyammonium phosphate (APP), adding polyaspartic acid (PASP), zinc sulfate heptahydrate (ZnSO 4 .7H 2 O) 30g / L, manganese sulfate monohydrate (MnSO 4 .H 2 O) 10g / L is constantly stirred;

[0023] Step S102, adding potassium nitrate (KNO 3 ) and boric acid (H 3 BO 3 ) continuously stirring, then adding agricultural streptomycin and glycerin and stirring evenly to obtain the foliar fertilizer mixture.

[0024] The specific preparation method of the foliar fertilizer mixture of the present invention is: 200 g of short-chain oligomeric ammonium polyphosphate (APP) accounts for 57.05% of the solid complex formulation, and 20 g of polyaspartic acid (PASP) accounts for the total complex formulation. 5.12%, dissolved in 500ml of water at 10°C-30°C and stirred evenly, adding zinc sulfate heptahydrate (ZnSO 4 .7H 2 O) 30g accounts for 8.55% of the solid complex dosa...

Abstract

The invention discloses a leaf fertilizer mixture and a preparation method thereof. The leaf fertilizer mixture comprises 200g / L of short-chain oligomeric ammonium polyphosphate (APP), 20g / L of polyaspartic acid (PASP), 20g / L of glycerol, 0.6g / L of agricultural streptomycin, 100 g / L of potassium nitrate (KNO3), 30g / L of heptahydrate (ZnSO4.7H2O), 10g / L of manganese sulfate monohydrate (MnSO4.H2O), and 10g / L of boric acid (H3BO3). When used, the leaf fertilizer mixture is diluted into 500-600 times; after being uniformly mixed, 100ml of the leaf fertilizer mixture is respectively sprayed on front and reverse surfaces of corn leaves and a part of stems per mu during the growth elongation period and the opening period of corns; the leaf fertilizer mixture is high in nutrient permeability; fertilizer drops easily permeate in leaves; the utilization rate of nutrients is high; and photosynthesis of leaves and lodging-resistant, disease- and insect-resistant and stress-resistant capabilities of corns are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a foliar fertilizer mixture and a preparation method thereof. Background technique [0002] Existing corn foliar fertilizers have low nutrient permeability to corn leaves, fertilizer droplets are not easy to penetrate into the leaves, and water drops of liquid fertilizer are easy to slip off the surface of the leaves, causing loss, low nutrient utilization, and the fertilizer liquid on the leaves for a long time Short, especially in windy and high temperature weather, spraying fertilizer will cause the fertilizer solution to dry quickly on the leaf surface, affecting the absorption of nutrients. If it rains soon after spraying fertilizer, the rain will wash away the liquid fertilizer and reduce the effect of foliar fertilization. Contents of the invention [0003] The invention provides a foliar fertilizer mixture and a preparation method thereof, aim...
