Abstract
Low yield of peanut production due to low soil fertility,and environmental pollution as a result of disorderly discharge of animal excretion from large-scale animal farms. Some researchers have proposed application of animal excretions as organic manure into farmlands and hold that it a win-win solution to the problems. However,some scientists have proved that long-term excessive application of pig manure will bring about heavy metal accumulations in the soil and pollution of groundwater with nitrate; and some others have found that application of pig manure,if low in rate,not only increases labor cost but also has little effect on yield. Hence,how to make use of organic manure properly to optimize crops in yield and soil in quality without any risk of environmental pollution has become a pressing issue. For that a filed experiment was carried out at the Yingtan National Agroecosystem Field Experiment Station located in Yujiang County,Jiangxi Province,a subtropical area of China,to tackle this problem. The experiment was designed to have six treatments,i. e. no fertilizer( CK),conventional chemical fertilization( T0),80% chemical fertilizer N plus 20% manure N( T20),60% chemical fertilizer N plus 40% manure N( T40),40% chemical fertilizer N plus 60% manure N( T60),and 20%chemical fertilizer N plus 80% manure N( T80),with a view to exploring effects of application of organic manure,relative to its rate,on yield of peanut,soil available nutrient and biological properties and further-on an optimal combination of chemical fertilizer with organic manure for peanut production in this area. So this study not only has its important theoretical significance in enriching the physiological study on nutrition and quality of peanut,but also possesses some practical meaning in reducing the waste of organic manure resources and alleviating the potential risk of application of organic manure polluting the environment. Results of the field experiment are encouraging.( 1) Combined application had significant effects of improving yield of peanut,the plants in Treatment T40 were the highest in pod yield,kernel yield,pods per plant,per hundred kernel weight,being 20. 14%,26. 92%,27. 87% and 7. 08%,respectively,higher than their respective ones in Treatment T0( 2) combination application of organic and inorganic fertilizer have great influence on the soil available nutrient. After harvesting the peanut,the T40 treatment of the available N,available P and available K increased by 17. 89% 、22. 96% 、12. 57%,respectively as compared with Treatment T0.( 3) Numbers of bacteria,actinomycetes and fungi were raised with the increase of amount combined application of organic and inorganic fertilizer.Compared to the T0,number of the three kind of microorganism were in creased by 71. 62% 、40. 42% 、43. 94%,respectively.( 4) Fertilization can significantly enhance the enzyme activity of urease,invertase,acid phosphatase. The enzyme activity of medium( T40) and high( T60,T80) level of combined application were much higher than that of the other treatments. The effect of low level of combined application( T20) was near to the pure inorganic fertilizer. Based on the above-described findings,it can be concluded that on the condition that equivalent N,P,K nutrients are supplied,the application of fertilizer containing 35% of N in the form of organic manure can not only turn large volumes of animal excretions into organic manure,,but also reduce the use of chemical fertilizer and improve the yield,quality and physiological properties of peanut in red soil areas,which means a great augmentation of economic value and social benefit.
