Description
Technical field
The present invention relates to fertilizer preparing technical field, and in particular to a kind of special drip irrigation fertilizer of carrot rich in N P and K and
Its preparation method.
Background technology
Drip irrigation fertilizer, is a kind of fertilizer applied with pouring, there is easy to use, crop easily to absorb due to drip irrigation fertilizer, fertilizer
The features such as effect is prominent, receives the welcome of vast farmerses；
Carrot, also known as carrot or sweet Xun, is the mutation of cicely, and this mutation is root meat with former mutation difference, long
Cone, thick fertilizer, takes on a red color or yellow, and carrot is crisp delicious, the nutritious homely vegetables of a germplasm, is have " glabrousleaf asiabell root "
Title.Carrot is rich in carbohydrate, fat, volatile oil, carrotene, vitamin A, vitamin B1, vitamin B2, anthocyanidin, calcium, iron
Contain a large amount of carrotene etc. nutritional ingredient carrot, the molecular structure of this carrotene enters equivalent to 2 vitamin As of molecule
After entering body, by the effect of enzyme in liver and mucous membrane of small intestine, wherein 50% becomes vitamin A, there is nourishing liver and improving eyesight,
Yctalopia can be treated；Carrotene is transformed into vitamin A, and vitamin A is the required material of bone normal growth development, is contributed to
Cell is bred and is grown, and is the key element of body growth, to promoting growing for infant significant.Vitamin A has
Help strengthen the immune horizontal bar in the front of a carriage used as an armrest energy of body, play an important roll during epithelial cell canceration is prevented.Lignin in carrot
Also immunity of organism mechanism can be improved, cancer cell is eliminated indirectly, because carrot has edibility and medical value higher, because
How this cultivates best in quality, nutritious healthy carrot has great importance, and the cultivation of carrot is wherein most attached most importance to
What is wanted is the administration of fertilizer, growing way, the absorption to nutrient and the demand to growing environment that it is directly connected to carrot,
But traditional fertilizer is often merely able to ensure the growth demand of crop in application, it is impossible to solve what is caused due to fertilising
Nutrient utilizes imperfection, causes the problem of soil hardening, and cannot solve the problems, such as heavy metal pollution of soil, thus
Can see how that developing one kind can either improve nutrient utilization rate, can effectively solve the problem that soil hardening, soil weight again
The fertilizer of rnetal contamination problem is modern agricultural development in the urgent need to therefore, the present inventor is by substantial amounts of experiment and research
There is provided a kind of special drip irrigation fertilizer of the carrot rich in N P and K and preparation method thereof.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of special drip irrigation fertilizer of the carrot rich in N P and K and its system
Preparation Method.
The present invention is achieved by the following technical programs：
A kind of special drip irrigation fertilizer of carrot rich in N P and K, it is made up of following raw material：Urea 44-64 parts, nitre
Sour ammonium 10-16 parts, potassium dihydrogen phosphate 12-18 parts, sulfate 9-19 parts, reaction promoter 14-20 parts, auxiliary material 8-14 parts, additive
5-9 parts.
The special drip irrigation fertilizer of the carrot rich in N P and K is made up of following raw material：Urea 49-59 parts, nitric acid

With reference to specific experiment example, the present invention is described further：
Experimental example 1
This drip irrigation fertilizer field demonstration test, experimental field ground is in Guizhou, has a moderate climate, with heavy rainfall, using every mu of field
Label is tested, and 10 mu of fields, the drip irrigation fertilizer prepared using conventional fertilizer application and conventional fertilizer application+the present embodiment 1-9 are selected altogether
Carrot experiment is carried out, experimental result is as shown in table 1：
The drip irrigation fertilizer field demonstration test of table 1
The plantation of carrot its yield is carried out by the way of conventional fertilizer application as seen from the above in theoretical value, and is used
The drip irrigation fertilizer that conventional fertilizer application+the present embodiment 1-9 is prepared carries out the plantation of carrot its yield and is not only above theoretical value but also remote
It is using conventional fertilizer application far above independent, therefore be that there is effect of increasing production higher using the plantation that the present invention carries out carrot.
Experimental example 2
Heavy metal-polluted soil treatment experiment：
Surveyed as carrier addition exogenous heavy metal pollutant with the free of contamination cinnamon soil in Guizhou Province and contained at its soil depth 5-20cm
Pb100mg/kg, Cd6mg/kg, Cr900mg/kg, Cu980mg/kg, using the soil as experiment soil, by the embodiment of the present invention
During the drip irrigation fertilizer prepared delivers experiment soil, heavy metal concentration inspection at soil soil depth 5-20cm is carried out after 15 days
Survey, its testing result is as shown in table 2：
The heavy metal-polluted soil of table 2 processes experimental result
From the foregoing, it will be observed that being delivered in experiment soil after 15 days using the drip irrigation fertilizer prepared in the embodiment of the present invention, soil
Content of beary metal at 5-15cm is significantly reduced, and illustrates that the thio sulfide contained in this drip irrigation fertilizer occurs with heavy metal ion
Reaction production precipitation, so as to heavy metal ion be fixed, prevents it from passing through leaching and footpath stream migration, in addition in this drip irrigation fertilizer
Thio sulfide valence heavy metal ions can also be reduced into lower valency, effectively reduce its toxicity and dissolubility.
