The real effectiveness of this organic fertilizer is verified for detection and the drop control of heavy metal in soil is acted on, the present inventor institute
It is tested in 500 mu of big Tanakas of early rice in the support institute of agricultural sciences of unit special commission, test result is as follows：
Manure use material type：Commercially available brand solid, Liquid organic fertilizer (control group), organic fertilizer of the invention (experiment
Group).
Test group：Experiment carries out in 500 mu of early rice experimental plots of live streaming, in the solid of 60 kilograms of straight preplant treatment/per acre
This validation group organic fertilizer makees base fertilizer；Then, respectively at rice seedling, tillering stage and boot stage, this verification is used in three times
Group organic fertilizer is used as foliar fertilizer, every time 100 milliliter/time, is watered 15 kilograms of progress foliar sprays every time；Other field pipes
Reason method drops the effect of control heavy metal with common crop field, later check test group organic fertilizer in large area Rice Production.
Control group：Control group carries out in 500 mu of early rice experimental plots being broadcast live with experimental group areal, is applied before live streaming
With 60 kilograms/per acre the commercially available machine fertilizer of solid make base fertilizer；Then, respectively at rice seedling, tillering stage and boot stage, in three times
It is used using commercially available machine fertilizer as foliar fertilizer, every time 100 milliliter/time, is watered 15 kilograms of progress foliar sprays every time；Other fields
Between management method with common crop field, examine the commercially available machine fertilizer of this control group to drop in large area Rice Production control heavy metal later
Effect.
Above-mentioned test group and China Resources collective inspection test center of control group produced paddy inspection China are detected, inspection
It is as follows to survey result：
Control group and test group submitted sample are respectively divided into three parts of inspections.
First part：
Submitted sample one (test group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.14mg/kg.
Submitted sample two (control group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.19mg/kg.
Decline 26.3% than control group using the cadmium metal content in the produced paddy of organic fertilizer of the present invention.
Second part：
Submitted sample one (test group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.15mg/kg.
Submitted sample two (control group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.32mg/kg.
Decline 52.1% than control group using the cadmium metal content in the produced paddy of organic fertilizer of the present invention；
Third part：
Submitted sample one (test group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.14mg/kg.
Submitted sample two (control group) predominantly detects heavy metal every 1, and wherein cadmium content (in terms of Cd) is 0.30mg/kg.
Decline 53.3% than control group using the cadmium metal content in the produced paddy of organic fertilizer of the present invention.
By above-mentioned three parts of detection data it is found that using the cadmium content mean reduction 43.9% in the produced paddy of the present invention.
And from the point of view of the output value of harvested per mu yield paddy, the average yield per mu value of experimental group is 1261.4 yuan, control group
Average yield per mu value is 1239.3 yuan, is higher than the per mu yield value of control group.
Apart from the above, " Ministry of Agriculture's rice and quality of item have also been sent to using the produced paddy of organic fertilizer of the present invention
Supervision and inspection center " is detected heavy metal therein, and the data after test can be found in shown in Fig. 1 to 2.
