Advantage of the present invention is:

Special fertilizer for sweet potato of the present invention has very high nitrogen content; high by the specific absorption of sweet potato; wherein lime nitrogen is a kind of nuisanceless, noresidue, free from environmental pollution; soil and the multifunctional fertilizer killing disease worm can be improved again; the organic additive added effectively improves water quality and topsoil, protects environment.

Embodiment

Embodiment 1

A kind of special fertilizer for sweet potato, it is made up of the raw material mixing of following weight parts (kilogram):

Urea 30, ammonium sulfate 20, monoammonium phosphate 25, bicarbonate of ammonia 20, ammonium polyphosphate 10, xanthohumic acid 3, Repone K 3, organic additive 14;

Described organic additive is made up of the raw material of following weight parts:

Leaf-humidified soil 30, swamp soil 40, lime nitrogen 7, aluminium hydroxide 3, bone black 10, carboxymethyl cellulose 2, Nafusaku 0.6;

Joined by above-mentioned Nafusaku in 10-15 times of water, stirring and dissolving, adds leaf-humidified soil, swamp soil, lime nitrogen, stir, under being placed in sunlight, doing to water, add above-mentioned aluminium hydroxide, bone black, insulated and stirred 3-5 minute at 100 DEG C, be cooled to normal temperature, add each raw material of residue, 200 revs/min of dispersed with stirring 12 minutes, sieve apparatus sieves, and obtains described organic additive.

Planting experiment:

Test is positioned at the modern garden of agricultural, Taihe County of Anhui Heng Jin agricultural development company limited circulation, and soil property is the soil that becomes silted up, middle fertility;

Test Fruit variety current main breed business potato 19;

Plot area: 60 ㎡ (4*15), random alignment, if three repetitions, rate of fertilizer application is every mu of 50kg.Row spacing 80CM, ridge height 30-40CM, ridge top width 30-40CM, single file is planted, and spacing in the rows is determined with density, spring red taro density 3000 plants/acre, summer red taro density 3500 plants/acre;

Spring, red taro was manually planted May 6, and average row is apart from 80cm, spacing in the rows 27.78cm, and planting density is 3000 plants/acre.Summer, red taro was manually planted June 7, and average row is apart from 80cm, spacing in the rows 23.8cm, and planting density is 3500 plants/acre.Before planting, unify tractor-ploughing, by test design fertilising, beat ridge, rate of fertilizer application is every mu of 50kg.The measure such as weeding, Tian Guan is identical with land for growing field crops.Summer, red taro was planted and growing period, and weather arid, sprays.Spring, red taro was planted and growing period, irrigated.Spring, red taro cut seedling results, 145 days breeding times September 27.Summer, red taro cut seedling results, 127 days breeding times October 11;

Spring red taro growing period, temperature on average 25.68 DEG C, >=10 DEG C of total effective temperature 2273.6 DEG C, gross precipitation 524.8mm, but precipitation is uneven, and late May, a quantity of precipitation reached 105.1mm, mid-July, a quantity of precipitation reached 136.9mm, at the beginning of 8 months, once quantity of precipitation is 72.6mm, and these three quantity of precipitation just reach 314.6mm, account for 60% of whole Precipitation During Growing amount.This year 7, August, continuous high temperature is unfavorable to spring red taro, reaches 34 days more than 35 DEG C of high temperature;

Summer red taro growing period, temperature on average 26.07 DEG C, >=10 DEG C of total effective temperature 2040.89 DEG C, quantity of precipitation 373.1mm.But precipitation is uneven, mid-July, a quantity of precipitation reached 136.9mm, and at the beginning of 8 months, once quantity of precipitation is 72.6mm, and this twice quantity of precipitation just reaches 209.5mm, accounted for 61.9% of whole Precipitation During Growing amount.7, August, continuous high temperature was unfavorable to summer red taro, reached 28 days more than 35 DEG C of high temperature.Because there being equipment of sprinkler irrigation, summer red taro growth can be promoted;

The spring red taro per mu yield using special fertilizer of the present invention is 2354.02kg, increases production 211.83kg, stimulation ratio 9.89% than conventional sealing fertilizer (15:15:15) (CK) every mu;

The summer red taro per mu yield using special fertilizer of the present invention is 2580.45kg, increases production 292.6kg, stimulation ratio 12.79% than conventional sealing fertilizer (15:15:15) (CK) every mu.
