Abstract
The invention belongs to the technical field of agriculture and relates to a foliar fertilizer for growth of sweet potatoes. The technical scheme includes that the foliar fertilizer is prepared from, by weight, 1 part of monopotassium phosphate, 0.8-1.5 parts of potassium nitrate, 0.8-2 parts of chitosan and 0.5-1 part of humic acid. The foliar fertilizer has advantages that synergistic effects are achieved due to matching of components in a composition according to a specific proportion, growth of the sweet potatoes is promoted, and yield is increased.
Description
Technical field
The present invention relates to the fertilizer of a kind of Radix Ipomoeae growth foliage-spray, belong to agricultural technology field.
Background technology
Radix Ipomoeae is a kind of the most healthy but also delicious food, and Radix Ipomoeae is precious from head to foot, and not only Radix Ipomoeae is edible, and Folium Ipomoea, stalk can cook the food of delicious food.The most edible Radix Ipomoeae, can reduce blood glucose and blood fat, and in recent years, the health value of Radix Ipomoeae is increasingly subject to people's attention, and even has Radix Ipomoeae can compare beautiful saying with Radix Ginseng.
Though Radix Ipomoeae has resistance to lean characteristic, but its trophophase is long, and absorption ability of nutrient is strong, consumes the nutrient in soil many.Therefore, on the basis of using sufficient base manure, apply certain foliage fertilizer, be necessary to improve yield, after especially Radix Ipomoeae enters Later growth, the absorbability of root system weakens, for preventing plant senilism, impose preferable fertilizer, on the one hand can grow with maintenance, on the other hand, mouthfeel can be improved.
Foliage fertilizer is the general designation of the fertilizer being provided nutrient substance by crop leaf for crop, is the supplementary, with the deficiency of quasi-complement Root Absorption nutrient of plant absorption nutritional labeling.Foliage dressing has instant effect, low cost, feature that loss is few.
At present, there is no commercially available Radix Ipomoeae growth foliage fertilizer.
Summary of the invention:
The goal of the invention of the present invention is to provide a kind of Radix Ipomoeae growth foliage fertilizer.
The technical scheme is that a kind of foliage fertilizer, it is characterised in that containing potassium dihydrogen phosphate, potassium nitrate, chitosan, humic acid.
Currently preferred technical scheme, it is characterised in that containing potassium dihydrogen phosphate 1 part, potassium nitrate 0.8-1.5 part, chitosan 0.8-2 part, humic acid 0.5-1 part.
Currently preferred technical scheme, it is characterised in that containing potassium dihydrogen phosphate 1 part, potassium nitrate 1.0 parts, chitosan 1 part, humic acid 0.6 part.
Currently preferred technical scheme, it is characterised in that containing potassium dihydrogen phosphate 1 part, potassium nitrate 1.2 parts, chitosan 1.3 parts, humic acid 0.8 part.
Currently preferred technical scheme, it is characterised in that containing potassium dihydrogen phosphate 1 part, potassium nitrate 0.9 part, chitosan 1.6 parts, humic acid 0.9 part.
This
In inventive technique scheme, potassium nitrate, it is provided that the nitrogen of plant growing and potassium.Potassium dihydrogen phosphate provides phosphorus and the potassium of plant growing.
The preparation method of the present composition, is ground to the powder that granularity is below 1mm respectively by potassium dihydrogen phosphate, potassium nitrate, chitosan, humic acid, takes the various components of formula ratio, mix homogeneously,.
The using method of the present composition: by described foliage fertilizer dilute with water 20～50 times, be sprayed on Radix Ipomoeae blade face.
The amount of application of described foliage fertilizer is preferably 50～100g/ mus.
Play one's part to the full in order to ensure fertilizer, preferably by described foliage fertilizer at the Later growth of Radix Ipomoeae, use 1-3 time.
Chitosan (chitosan), also known as chitosan, is that the chitin (chitin) being widely present by nature obtains through deacetylation, and chemical name is Chitosan (1-4)-2-amino-B-D glucose.Being the unique alkaline polysaccharide having now been found that, people are studying chitosan in medicine, agricultural, industry, the application in foods and cosmetics field.
Chitosan is positively charged polyelectrolyte in the solution, has the strongest adsorptivity, film property and permeability, can well control foliage fertilizer composition and be trapped in the surface of plant leaf, and progressively absorb, not affected by the natural cause such as strong wind and dew.
Humic acid is the larger molecular organics matter being widely present in nature, be widely used in agriculture, woods, herd, oil, chemical industry, building materials, medical and health, the every field such as environmental protection.Advocate the most now ecological agriculture construction, pollution-less agriculture production, pollution-free food, pollution-free environmental protection etc., more make " humic acids " to enjoy high praise.
Beneficial effect: the invention provides the Radix Ipomoeae growth foliage fertilizer of a kind of green, environmental protection, in the foliage fertilizer that the present invention provides, the water solublity of each composition is good, can directly be sprayed on crop leaf, and holdup time on blade face is long, beneficially crop leaf absorbs.In the present composition, each component realizes synergism after coordinating with specific ratio, can promote that Radix Ipomoeae grows, and improves yield.
It has been surprisingly found that use the Radix Ipomoeae of product of the present invention, during depositing, Radix Ipomoeae does not has sick, to become corruption situation.
