Problems solved by technology

[0002] Most of the existing foliar fertilizers are used to improve photosynthetic efficiency of crops, resist diseases, promote root development, increase flowers and preserve fruits, etc., and are suitable for grasses, legumes, melons, vegetables and fruit trees and other crops. The nature of the fertilizers required during the growth period is different, and it is difficult to topdress the soil root system. The main function and effect of the existing foliar fertilizers are single, and the ability to regulate the whole growth period of sweet potatoes is poor. There is no special foliar fertilizer for sweet potatoes.

Embodiment 1

[0023] The sweet potato foliar fertilizer mainly includes an aqueous solution composed of nutrient elements and plant growth regulators by weight percentage, wherein the nutrient elements are: urea 18%, potassium dihydrogen phosphate 6%, magnesium sulfate 6%, ferrous sulfate 3%, 3% of copper sulfate, 3% of zinc sulfate, 3% of manganese sulfate; the plant growth regulator is: sodium nitrophenolate 0.0006%, diethylaminoethanol caproate (DA-6) 0.001%, uniconazole 0.01% ; Analytical pure N, N-dimethylformamide 2%, the balance is deionized water.

[0024] Take each component according to the above content, first dissolve the nutrient elements urea, potassium dihydrogen phosphate, magnesium sulfate, ferrous sulfate, copper sulfate, zinc sulfate and manganese sulfate in deionized water at room temperature in sequence, and stir while dissolving; After it is completely dissolved, add sodium nitrophenolate and diethylaminoethanol hexanoate to dissolve completely to obtain a mixed soluti...

Embodiment 2

[0027] The sweet potato foliar fertilizer mainly includes an aqueous solution composed of nutrient elements and plant growth regulators by weight percentage, wherein the nutrient elements are: 30% urea, 6% potassium dihydrogen phosphate, 6% magnesium sulfate, 3% ferrous sulfate, 3% of copper sulfate, 3% of zinc sulfate, 3% of manganese sulfate; the plant growth regulators are: sodium nitrophenolate 0.0006%, diethylaminoethanol caproate (DA-6) 0.002%, uniconazole 0.02% ; Analytical pure N, N-dimethylformamide 2%, the balance is deionized water.

[0028] The method of preparation and use is the same as in Example 1.

Embodiment 3

[0030] Sweet potato foliar fertilizer mainly includes an aqueous solution composed of nutrient elements and plant growth regulators by weight percentage, wherein the nutrient elements are: urea 24%, potassium dihydrogen phosphate 6%, magnesium sulfate 6%, ferrous sulfate 3%, 3% of copper sulfate, 3% of zinc sulfate, 3% of manganese sulfate; the plant growth regulator is: sodium nitrophenolate 0.0006%, diethylaminoethanol caproate (DA-6) 0.0015%, uniconazole 0.015% ; Analytical pure N, N-dimethylformamide 2%, the balance is deionized water.

[0031] Preparation and use method are with embodiment 1,

The foliage fertilizerfor sweet potatoes provided by the invention is of a promoting and controlling combined type and is applicable to both the early growth stage and later growth stage.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a sweet potato foliar fertilizer and its application method. Background technique [0002] Most of the existing foliar fertilizers are used to improve photosynthetic efficiency of crops, resist diseases, promote root development, increase flowers and preserve fruits, etc., and are suitable for grasses, legumes, melons, vegetables and fruit trees and other crops. The nature of fertilizers required during the growth period is different, and it is difficult to topdress the soil root system. The main function and effect of existing foliar fertilizers are single, and the ability to regulate the whole growth period of sweet potatoes is poor. There is no special foliar fertilizer for sweet potatoes. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a sweet potato promotion-control combi...
