Description
Technical field
The invention belongs to the evaluation and exploration technology field of agriculture organic crops fertilizer, and in particular to one kind is applied to underground block
The high efficiency liquid fertilizer of stem class crop.
Background technology
Tuber cropses refer to a kind of crop using underground metamorphosis stem as harvest fruit.The crop subterranean stem end forms swollen
Big and irregular bulk, stem tuber are adapted for the abnormal stem stored nutriment and survived the winter.Top is loose, there is the parenchymal tissue of prosperity,
The abundant nutriment of storage.There are many eyes on the surface of stem tuber, typically makees helical arrangement, has 2-3 axillary bud in eye, only
One of axillary bud is easily sprouted, and can send forth branches, therefore stem tuber is available for breeding to be used.The top of stem tuber has a terminal bud, such as
The stem tuber of potato is more typical.Potato undergland shoot sprawl growth in soil layer, when extending 9-12 centimetres, end is swollen
Greatly, formed with the plump stem tuber between pipe nipple.On the stem tuber grown up to, there is perithelium on top layer, above there is a small number of hole skins.In the horizontal stroke of stem tuber
Cortex, outer bast, xylem, endophloem and the marrow in center are still separated on section., can be with from profile or construction
It is the metamorphosis of stem to illustrate it.Carrot, ternip, potato, violet cabbage, Chinese yam and lotus root, taro, sweet potato, ginger are common
Excavating machine of underground tuber.
Excavating machine of underground tuber is more prone to grow various diseases, causes the life of crop due to being that stem tuber directly contacts soil
Long and yield all by different degrees of destruction, existing fertilization mode be blended in more using solid granulates fertilizer in planting site or
Person directly uses on crop surface soil, has aggravated the generation of disease, lopsided product easily occurs.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of high efficiency liquid suitable for underground tuber cropses
Fertilizer, the liquid fertilizer for preparing to obtain can suppress disease invasion and attack crop stem tuber epidermis, and energy specifically for underground tuber cropses
Enough promote expanding for stem tuber.
The present invention is achieved by the following technical solutions：
A kind of high efficiency liquid fertilizer suitable for underground tuber cropses, it is made up in parts by weight of following raw material：Urea 300-
320 parts, calcium superphosphate 90-110 parts, potassium nitrate 80-90 parts, calcium silicate fertilizer 50-60 parts, flyash 40-50 parts, plant extraction liquid
30-40 parts, bacteria residue 20-25 parts, Oletum Columba livia 20-22 parts, wormcast 18-20 parts, animal feather 15-17 parts, charcoal 10-15
Part, microbial-bacterial fertilizer 5-10 parts, micro- fertile 5-8 parts, mixing enzyme preparation 0.4-0.6 parts, biogas slurry 150-180 parts, water 400-450 parts,
Its preparation method comprises the following steps：
（1）Urea, calcium superphosphate, potassium nitrate, calcium silicate fertilizer, flyash, bacteria residue and microbial-bacterial fertilizer are dissolved using water, obtained
Solidliquid mixture, the mixture is quickly stirred 20-25 minutes at normal temperatures, mixing speed is 450-500 revs/min, heating
Continue to stir 30-40 minutes under 150-200 revs/min after to 50-60 DEG C, obtain the homogeneous mixture of quality；
（2）Oletum Columba livia, wormcast, animal feather are put into biogas slurry, mixing enzyme preparation sealing is added, is issued at 30-35 DEG C
Ferment carries out anaerobic fermentation, and obtained biogas is collected into utilization in fermentation, until after being produced without biogas, zymotic fluid is passed through
60-80 mesh screens, obtained filtrate are added to step（1）Stirred as one in gained mixture；
（3）Residual components are added to step（2）In gained mixed liquor, after stirring, adjusted using acid-base modifier to PH
It is worth for 7.0-7.2, after standing 2-3 hours, removes sediment and flocculate using 60-80 mesh screens, obtain liquid fertilizer,
It is 70-80% that reduction in bulk is concentrated in vacuo at 40-50 DEG C.
Further described as to such scheme, described plant extract liquid and preparation method thereof is：Prepare 1 kilogram of plant extraction liquid
Need to weigh 0.3-0.5 kilograms of garlic, 0.3-0.4 kilograms of purslane, 0.2-0.3 kilograms of Alfalfa, tea free 0.1-0.2 thousand
Gram, 0.1-0.2 kilograms of eucalyptus leaves, 0.3-0.5 kilograms of water, composition than water is obtained after microwave crushes to solid-liquid mixing
Thing, 80-90 DEG C is heated to, stirs 10-15 minutes, the ultrasonic extraction 20-30 minutes under 35-40KHz, then be placed in 5000-6000
10-15 minutes are centrifuged under rev/min, carries out being filtered to remove precipitation, filtrate is obtained, after being watered.
