Abstract

The invention discloses a composite foliar fertilizer special for liquid pomegranate. Water is taken as a solvent; the fertilizer comprises nutrient elements such as nitrogen, phosphorus, potassium, zinc, boron and iron and aids; the total content of the nutrient elements (N+P2O5+K2O+Zn+B+Fe) is more than or equal to 150 g/L; the mass ratio of N to P2O5 to K2O to Zn to B to Fe is (13-16):(1.5-2.5):(5-7):(3-5):(1.5-2.5):1; the content of a chelating agent is between 15 and 25 g/L; and the content of a wetting agent is between 0.08 and 0.15 g/L. Before being applied, the composite foliar fertilizer is diluted by 500 to 800 times with water. 100 to 150 kilograms of diluent is added into every mu of farmland. The foliar fertilizer is applied before a germination period, after a blooming period, during a swelling period, before a harvesting period and after the harvesting period respectively, so that the yield of pomegranate can be increased by about 10 percent.

Description

A kind of composite foliar fertilizer special for liquid pomegranate

One, technical field

The present invention relates to a kind of chemical fertilizer, particularly polyelement composite fertilizer exactly, is a kind of composite foliar fertilizer special for liquid pomegranate.

Two, background technology

It is all abundanter to contain organic acid, vitamins C and B in the pomegranate fruit, and the mineral substance such as protein, fat and calcium, phosphorus, potassium are still arranged in addition.Pomegranate can prevent and treat halitosis, antidiarrheal sterilization, promote the production of body fluid to quench thirst, beautifies skin.The fruit of pomegranate, pericarp, root and Hua Junke make medicine.Pomegranate has the multiple nutrients nourishing function.Huaiyuan, Anhui pomegranate cultivation history is long, and excellent quality is long-cherished, usually mid or late March germinations of sprouting, budding mid-April, May flower opened just now, by the end of June, July initial bloom stage substantially finish, mid-September, fell leaves mid-November to the early October fruit maturation.In cultivation, Huaiyuan orchard worker has accumulated abundant production experience, need the essential nutritive elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, zinc, manganese, copper, iron, boron, molybdenum in the Pomegranate Growth process, at present, except nitrogen phosphorus potassium, pomegranate field, Huaiyuan also lacks the trace elements such as zinc, boron, iron gradually.When pomegranate lacks zinc, germinate spring, leaf is little in evening, and fruit is little, and tree crown is sparse, and output is very low.During boron deficiency, irregular gangrene appears in the top tip, the blade yellow, and the top top drying is withered.Leaf chlorosis yellow during the pomegranate iron deficiency.Therefore, must get hold of fertilizer practice.Carry out the fertilising work in four periods: (1) fruit picking fertile (base manure), take fertilizer as main.(2) fertilizer applied in the spring season (topdressing before the rudiment and after spending) is take nitrogenous fertilizer as main.(3) fertilization in summer (expanding stage topdresses), nitrogen, phosphorus, potassium, boron, zinc, iron etc. are used.(4) fertilizing in autumn (topdressing before adopting).Take available potassium as main, can promote Fruit, improve fruit quality.

Leaf dressing mainly is to enter blade by the pore on the blade and stratum corneum, then transports to tree each organ in the body, generally sprays can be absorbed by blade by 2 hours in rear 15 minutes.Leaf dressing is an efficient fertilizing type.

Three, summary of the invention

The present invention is intended to for pomegranate provides a kind of liquid-type compound foliar fertilizer special, and technical problem to be solved is the proportionlity of various nutrient elements and the consistency in solution thereof.

The alleged nutritive element of the present invention refers to nitrogen, phosphorus, potassium, zinc, boron, iron etc., is selected from urea, potassium primary phosphate, saltpetre or vitriolate of tartar, zinc sulfate, active boron or borax, ferrous sulfate, and its content is respectively with N, P ₂O ₅, K ₂O, Zn, B, Fe meter.When calculating content, take potassium primary phosphate as example, outside the dephosphorization, also potassium wherein should be counted in total potassium, the rest may be inferred by analogy.

This foliage fertilizer is the foliage fertilizer take water as solvent, comprises nitrogen, phosphorus, potassium, zinc, boron, iron and composite assistant, and difference with the prior art is nutritive element (N+P ₂O ₅+ K ₂O+Zn+B+Fe) content is greater than 150g/L, and its mass ratio is: N: P ₂O ₅: K ₂O: Zn: B: Fe=(13-16): (1.5-2.5): (5-7): (3-5): (1.5-2.5): 1.

Described composite assistant comprises sequestrant and wetting agent.Sequestrant is selected from EDTA, quadrol or citric acid etc., and content is 15-25g/L, and its effect is to form inner complex with trace element, thereby suppresses the generation of insoluble phosphate.Wetting agent is selected from anionic or nonionic surface active agent, such as alkyl-sulphate, alkylbenzene sulfonate, lauroyl diethanolamine, coconut oil diethanolamine or fatty alcohol-polyoxyethylene ether etc., content is 0.08-0.15g/L, its effect is the surface tension that reduces solution, improve solution in the blade face wettability of the surface, make it even spread, prevent that pearl from falling, prolong solution residence time of blade surface to guarantee that pomegranate is to the abundant absorption of nutrient.

Described active boron is four water eight borate two sodium (Na ₂B ₈O ₁₃4H ₂O), boracic 20.9% is a kind of new and effective instantly-soluble borate, also claims instant boron.

Nitrogen, phosphorus, potassium, zinc, boron and iron are necessary in this composite foliage fertilizer, but each element ratio can adjust in above-mentioned given range depending on particular case according to the principle of soil testing and fertilizer recommendation, if then can select N: P such as the ZINC IN SOIL element is abundant ₂O ₅: K ₂O: Zn: B: Fe=(13-16): (1.5-2.5): (5-7): 3: (1.5-2.5): 1, if waning, the ZINC IN SOIL element then can select N: P ₂O ₅: K ₂O: Zn: B: Fe=(13-16): (1.5-2.5): (5-7): 5: (1.5-2.5): 1, the rest may be inferred by analogy.

The preparation method of this foliage fertilizer be will metering nitrogen, phosphorus and the potassium raw material solution A that obtains soluble in water, the pH value of regulating described solution A with sulfuric acid gets solution B to 3-4; Zinc, boron and the ferro element raw material solution C that obtains soluble in water with metering; The composite assistant that adds metering in the described solution C gets solution D in the 50-80 ℃ of lower 1-2h of stirring; Described solution B and described solution D are mixed and add water to certain volume, remove by filter at last the non-water soluble impurity of bringing in the raw material and get product.

This composite foliage fertilizer is watered dilution 500-800 doubly when using, mu use diluent 100-150kg, before rudiment and after spending, expanding stage, adopt before and adopt after spray respectively this foliage fertilizer, pomegranate output can improve about 10%, quality is obviously improved, and ensures next pomegranate output in season.When spraying, be sprayed onto vacuum side of blade as far as possible, and should be without rain the time before at 10 o'clock in the morning or be good after at 4 o'clock in afternoon.Rain if spray to meet in the rear 5h, then should mend and execute.
