2. experimental result
2.1 polyamines complexing agents are on the impact of crop yield
As can be seen from Table 1, corn, in such as 2012 and 2013 time of normal not too arid, uses polyamines complexing agent to increase production 35kg/ mu and 52kg/ mu respectively, at dry year, such as 2011, use polyamines complexing agent can increase production 77kg/ mu, and obviously can reach water-saving result.
Table 1 polyamines complexing agent is on the impact (kg/ mu) of corn yield
As can be seen from Table 2, wheat, in such as 2014 time of normal not too arid, uses polyamines complexing agent can increase production 38kg/ mu, at dry year, such as 2012 and 2013, use polyamines complexing agent can increase production 95kg/ mu and 85kg/ mu, and obviously can reach water-saving result.
Table 2 polyamines complexing agent is on the impact (kg/ mu) of wheat yield
In a word, as can be seen from our land for growing field crops checking, use the polyamines complexing agent strengthening crop drought resistance, can obviously strengthen crop drought resistance ability, improve crop yield, particularly freshwater resources are day by day deficient at present, and groundwater resources are precious, use polyamines complexing agent under the prerequisite ensureing output, the object of water saving can be reached.We have also carried out extensive experiment in District, Xinyang Area, Henan Province Huaibin County, respond well, and (1.5 yuan/mu) with low cost, so, be worth spread.
The detection of soil residue after 2.2 use polyamines complexing agents
As can be seen from table 3 and table 4, complexing agent uses the soil residual quantity of 3 years extremely low, and all the components of complexing agent is all almost Crop.So we may safely draw the conclusion, polyamines complexing agent is used to pollute soil is useless.
The processed group soil residual quantity of table 3 corn polyamines complexing agent compares (detecting after harvest corn)
The processed group soil residual quantity of table 4 wheat polyamines complexing agent compares (detecting after harvesting wheat)
To people and animals' damage evaluation after 2.3 use polyamines complexing agents
Three kinds of composition polyamines, chitin and succinic acid involved in the present invention are normal metabolite in organism, after complexing agent is absorbed by plants, the overwhelming majority is converted into normal metabolite in other organism by plant metabolism, few part is only had to be absorbed by animal, even if these are seldom by complexing agent composition that animal absorbs, its concentration is also well below the concentration (as shown in table 5) that people and animals itself are synthesized, and can by animal trans-utilization, these viewpoints are generally accepted by Chinese scholars.
