Abstract
The invention relates to a compound fertilizer for agricultural production, in particular to a special fertilizer for sweet potato. The special fertilizer for the sweet potato is characterized in that the special fertilizer is formed by mixing ammonium chloride, urea, monoammonium phosphate, ordinary superphosphate, potassium chloride and other raw materials according to the mixture ratio; the special fertilizer comprises the following raw materials in weight percentage: 10 to 20 percent of the ammonium chloride, 11 to 24 percent of the urea, 0 to 24 percent of the monoammonium phosphate, 12 to 36 percent of the ordinary superphosphate and 33 to 42 percent of the potassium chloride; the total nutrient content of the special fertilizer for the sweet potato is between 35 and 48 percent, wherein the nitrogen content (N) is between 10 and 25 percent; the phosphorus pentoxide content (P2O5) is between 5 and 8 percent; and the kalio content (K2O) is between 20 and 25 percent. A method for producing the fertilizer comprises the following steps: according to the mixture ratio, the ammonium chloride, the urea, the monoammonium phosphate, the superphosphate, the potassium chloride and other raw materials are mixed, crushed, put to a stirrer, stirred and evenly mixed to prepare the special powdery fertilizer for the sweet potato; and the special powdery fertilizer for the sweet potato is pelletized and is dried at a temperature of between 60 and 80 DEG, thereby obtaining the special fertilizer for commercial sweet potato. The special fertilizer for the sweet potato can meet the needs of the growth and development of the sweet potato on several main nutritive elements, in particular potassium nutrition which can promote the expansion of root tuber and increase the output of fresh potato.
Description
Technical field
The present invention relates to agriculture production compound fertilizer, particularly a kind of special fertilizer for sweet potato.
Background technology
Sweet potato has another name called pachyrhizus, Ipomoea batatas, sweet potato etc.Sweet potato is one of stable high yield food crop.It has wide adaptability, strong stress resistance, and characteristics such as drought-enduring, anti-ridge, disease and pest are less, plantation on water, fertile condition are ploughed preferably, general per mu yield can reach the 2.5-3 metric ton.Therefore, in the grain-production of development China, sweet potato occupies certain critical positions.
Sweet potato is that absorption ability of nutrient is strong, needs fertile more crop, must supply with its enough nutrient, just can give full play to the characteristic of its high yield.According to one's analysis, in per 500 kilograms of bright potatos nitrogenous 1.75 kilograms, 0.9 kilogram in phosphorus, 2.75 kilograms in potassium.Potassium is at most plain in the required main nutrient of sweet potato, and nitrogen takes second place, and phosphorus is minimum.
Potassium can promote the formation and the transportation of carbohydrate, promotes cambial activity, enriches potash fertilizer and can promote the piece root to increase, and increases starch content, and storage endurance.During potassium deficiency, initial stage internode, petiole shorten, and blade diminishes; Crease blade folds down turnup, and the blade dehydration is withered and yellow, shift because potassium is plain, and serious minus green between old vein, the leaf back spottiness, stem is less climing and growth is slow.
Nitrogen is the main component of protein, leaf margin element etc., and it has the effect that promotes the cauline leaf growth.If the nitrogenous fertilizer deficiency, the little look Huang of leaf, the cauline leaf poor growth, the branch blade is less, the accumulation of unfavorable photosynthetic crop and product thereof.If nitrogen is too much, then cauline leaf excessive growth, the accumulation center rests on over-ground part for a long time, do not shift to root, and nitrogen content is many in the blade, and sugar degree is few, influences the speed that the piece root expands.
Phosphorus is protoplasma and nuclear important component, and can promote the division of formation, running and the cell of carbohydrate, and increasing the p application rate can promote the piece root to expand, and sweet taste increases, and improves quality and storage endurance.
In recent years, along with the increase of nitrogen fertilizer amount and improving constantly of yield of sweet potato, the serious disproportion of nitrogen, phosphorus, potassium three elements input amount shows nitrogen surplus, moderate, the plain wretched insufficiency of potassium of phosphorus element, and the plain loss of current potassium is the main factor that the restriction yield of sweet potato increases.Therefore, reducing nitrogenous fertilizer on the sweet potato crop, stablize phosphate fertilizer, enrich potash fertilizer is the task of top priority that sweet potato produces, be to increase yield of sweet potato, improve the sweet potato quality, reduce agricultural cost, improve the important behave of soil environment, big area is promoted special fertilizer for sweet potato important practical sense.
Summary of the invention
The purpose of this invention is to provide a kind of special-purpose fertilizer, a kind of special fertilizer for sweet potato particularly is provided.According to vast knob soil characteristic, the nutrient requirement by the sweet potato growth obtains the high special fertilizer for sweet potato of a kind of potassium content by reasonable blending.
Special fertilizer for sweet potato is to be mixed by proportioning by ammonium chloride, monoammonium phosphate, calcium superphosphate, Repone K, and its raw material weight per-cent is:
Ammonium chloride: 10-20%
Urea: 11-24%
Monoammonium phosphate: 0-12%
Calcium superphosphate: 12-36%
Repone K: 33-42%
Above-mentioned special fertilizer for sweet potato total nutrient content 35-48%, wherein nitrogenous (N) 10-15%, Vanadium Pentoxide in FLAKES (P
2O
5) 5-8%, potassium oxide (K
2O) 20-25%.
By said ratio raw materials weighing ammonium chloride, urea, monoammonium phosphate, calcium superphosphate, to mix, pulverize by the proportioning raw materials weighing, putting into agitator mixes, promptly make the powdery special fertilizer for sweet potato, again with the granulation of powdery special fertilizer for sweet potato process, and under 60-80 ℃ of temperature, dry, promptly make the commodity special fertilizer for sweet potato.
