The compound fertilizer comprises the following raw materials by mass: 8-16 parts of urea, 20-25 parts of monoammonium phosphate, 24-36 parts of potassium sulfate, 20-50 parts of weathered coal, and 6 parts of bentonite. The compound fertilizer special for sweet potatoes involve in the invention is a compound fertilizer that is formed by mixing of a natural organic matrix and an inorganic fertilizer and has the characteristics of simple production process, low cost, environmental-friendliness, high fertilizer utilization rate, production increase and efficiency improvement, etc.
Description
Technical field
The present invention relates to a kind of sweet potato compound fertilizer special and preparation method thereof, belong to field of fertilizer manufacturing.
Background technology
In recent years, the research and development of new-type fertilizer and the emphasis of application turn to composite fertilizer by simple ore matter fertilizer both at home and abroad.Crop compound fertilizer dedicated due to nutritive element abundant species, reasonable ratio, use conveniently, deeply be subjected to the welcome in market.Sweet potato is only second to paddy rice in sown area and the ultimate production of China, wheat and maize occupies the 4th.Sweet potato, except as feed and healthcare product, is also the important source material of hundreds of Industrial products simultaneously, can be rated as cheap renewable energy resources crop, in national economy, accounts for extremely important status.But aborning because former sweet potato is planted in barren or frontier area mostly, add the fertilising idea that a lot of peasants are old, relatively too much to the amount of application of nitrogenous fertilizer, this just causes in barren ground can obtain high yield, yet can cause the underproduction on the contrary on the soil of high fertility.In order to address this problem, effective means is to consider region characteristic and growth of sweet potato different steps to the Absorption Characteristics of each nutritive element, uses the fertilizer with long-acting releasing effect.
Summary of the invention
For the deficiencies in the prior art, the present invention, according to the nutrient uptake feature of Huang-Huai Area soil characteristic and growth of sweet potato growth, provides a kind of matrix class sweet potato compound fertilizer special with certain slow release effect.
Technical scheme of the present invention is as follows:
A kind of sweet potato compound fertilizer special, raw materials quality part is composed as follows: 8～16 parts, urea, 20～25 parts of monoammonium phosphates, 24～36 parts of vitriolate of tartar, 20～50 parts of weathered coals, 6 parts of wilkinites.
One of preferred sweet potato compound fertilizer special formula as following A～C in the present invention:
A. sweet potato compound fertilizer special, raw materials quality part consists of: 8 parts, urea, 20 parts of monoammonium phosphates, 36 parts of vitriolate of tartar, 30 parts of weathered coals, 6 parts of wilkinites; This sweet potato compound fertilizer special nutrient content is N:P
2O
5: K
2O=6:8:18, be particularly suitable for using as base manure in the higher plot of basic soil fertility.
B. sweet potato compound fertilizer special, raw materials quality part consists of: 12 parts, urea, 25 parts of monoammonium phosphates, 30 parts of vitriolate of tartar, 27 parts of weathered coals, 6 parts of wilkinites; This sweet potato compound fertilizer special product nutrient content is N:P
2O
5: K
2O=8:10:15, be particularly suitable for using as base manure in the medium plot of basic soil fertility.
C. sweet potato compound fertilizer special, raw materials quality part consists of: 16 parts, urea, 25 parts of monoammonium phosphates, 24 parts of vitriolate of tartar, 29 parts of weathered coals, 6 parts of wilkinites; This sweet potato compound fertilizer special product nutrient content is N:P
2O
5: K
2O=10:10:12, be particularly suitable for using as base manure in the lower plot of basic soil fertility.
Sweet potato compound fertilizer special provided by the invention, the quality proportioning of nitrogen (N), phosphorus, potassium is 6～10:8～10:12～18.
The present invention also provides a kind of preparation method of sweet potato compound fertilizer special, comprises the following steps:
At first by the formula requirement, take each component raw material; through pulverizing 120～150 orders, by batch mixer, fully mix, then by travelling belt, enter the Squeezinggranulator granulation; through sieving and using the polishing machine polishing, obtain the fertilizer finished product of particle diameter 2～4.5mm again.After crushed, returning charge is granulation again for the fertiliser granulates that is greater than 4.5mm that above-mentioned steps sieves out, and diameter is less than the directly returning charge granulation of fertiliser granulates of 2mm.
Advantage of the present invention is as follows:
1, nutrient reasonable ratio, production technique are simple
Sweet potato compound fertilizer special of the present invention has the characteristics such as reasonable ratio, manufacturing process be simple, with low cost.Can effectively improve sweet potato root tuber output and nutritional quality, also significantly improve simultaneously this season utilization ratio of npk nutrient.
2, has certain slow release effect
In order to estimate its slow release effect, adopt intermittently sand post drip-rinsing process evaluation of measuring.Result shows: the cumulative release amount of the nitrogen phosphorus potassium of the inorganic instant fertilizer of nitrogen phosphorus potassium reaches respectively 80%, 80% and 68% of total burst size after the 1st drip washing, and the n p k nutrition in fertilizer after the 3rd drip washing just almost all discharges; Nitrogen phosphorus potassium cumulative release curve in sweet potato special slow release Chemical Mixed Fertilizer is relatively slow, and after the 1st drip washing, the preparation of each element is between 15～45%, and the n p k nutrition after the 3rd drip washing in fertilizer is respectively 85%, 83% and 75% of total burst size; To each nutritive element after the 6th drip washing, just substantially discharge complete.Can draw thus, sweet potato compound fertilizer special of the present invention can extend fertilizer efficiency; Owing to having added weathered coal, can promote the absorption of sweet potato to moisture and nutrient simultaneously, promote the conversion of matter and energy, increase yield of sweet potato.
