Effects Of Different Organic Fertilizers On Corn Quality And Heavy Metals Absorption

In this paper,long-term experimental area,with the inorganic fertilizer application on the basis of a choice of three different sources of organic fertilizer:herbaceous plant remains(J), woody plant remains(S) and animal excrement(L).They will be with inorganic fertilizers (NPK) by a ratio of Oxfam into the soil,of corn on their growth and development,quality and the impact of heavy metals in the system.Test result enunciation,Different sources of organic manure and their combined application on corn and the quality of their heavy metal content of a significant difference.Result is as follows:1.Single application processing,S processing plant height and leaf area of the largest rate of increase,L corn on the condition that the birth of corn ear length,ear and a few of the seed weight have significantly improved;The combined application processing compared with the control,L+NPK deal with the obvious promotion of the reproductive process corn,J+NPK deal with the obvious promotion of corn plants and the growth of leaf area,S+NPK on the reproductive status of corn has increased the most obvious.2.Whether single application or combined application of the circumstances,increased by varying degrees of chlorophyll in the leaves of maize in,one to deal with J,J+NPK deal with the best,the combined application must be dealt with the chlorophyll content higher than the single application;Whether the corn is the single application or with organic fertilizer, corn jointing stage of the NDVI values do not change the larger,this shows that corn in the jointing,the different fertilization of corn has not been a clear growth of the nutritional prominent role.3.All processing,J+NPK on corn MDA most obvious effect of the decrease.In the single application of treatment,L on the starch content of corn increased the most obvious;Combined application of the S+NPK deal with the starch content of the highest, 80.5 percent higher than the control.Different sources of organic fertilizer and with giving control compared to a different degree of increase in the protein content of corn,which is the biggest increase in L+NPK treatment,reaching 207.4 percent.Corn on the content of free amino acids,single application processed only deal with the control S,showed an upward trend in other;combined application processing only S+NPK deal with the control and treatment are significantly higher than other control.In addition to the J handle the increased free fatty acid content,other treatments are reduced free fatty acid content of corn,the decline in the L+NPK and J+NPK most obvious.4.L+NPK deal with the entire increase in the amount of N most obvious source of woody single application can effectively improve maize grain and straw in the whole N content.In addition to dealing with S and J deal with,the other handling of a significant increase in maize grain and straw in the whole P content.All processing of maize grain and straw in the whole of K has obviously role in promoting,L+NPK processing of maize grain and straw K-wide increase of the best effect.5.In addition to dealing with J,S+NPK treatment reduced the corn leaves in the Cu content,the other dealing with all the leaves of maize increased by the effective Cu;the maize grain in the Cu content,whether alone or with Shi Shi did not increase;When single application of effective promotion of the corn stalks in the absorption of Cu,and the combined application did not increase the corn stalks in the Cu content.In addition to L-processing and handling J,S+NPK handling of the Zn is less than control,the other dealing with all the leaves of maize increased volume of Zn,to deal with the S-Zn of the most obvious effect of the increase;L,in addition to handling all the processing, increases the content of maize grain in the Zn,S+NPK processing of corn seed containing the highest Zn,12.3%higher than that of control,to achieve significant difference;Corn stalks in the handling of all Zn both have different degrees of increase,the single application of J when dealing with the highest volume of Zn.Three different sources of organic fertilizer single application processing time in corn leaves Cd,Pb content are different levels of lower;three Effect of long-after L+NPK treatment failed to reduce Cd content in the leaves,while the other dealt with all of the corn leaves in the lower Cd,Pb content;only single application processing L treatment while reducing the grain of Cd,Pb content,application processing and distribution have different levels of maize grain in the lower Cd,Pb content;In addition to dealing with single application of L handle all the corn stalks in the lower Cd,Pb content;In addition to treatment with Shi L+NPK treatment,the other dealing with the Cd,Pb levels have decreased,and J+ NPK treatment of Cd,Pb of the most obvious decline.6.The different source is organic fatty and it goes together with the living creature yield that raised corn,going together with influence of the processing upon the corn living creature yield among them obvious,the S+NPK processing is the biggest to the exaltation range of corn living creature yield.
