Abstract
Slope field has been one of the major factors limiting peanut(Arachis hypogea) production in Shandong province.Improving fertilizer use efficiency and reducing nutrients loss play an important role to obtain high yield and quality in slope field.Previous studies have shown controlled release fertilizer can release nutrients to soil during peanut growing season and improve yield and quality.In the experiment,four treatments of man-made slopes in 0°,5°,10°,and 15° were set in field conditions.The results showed that the controlled release fertilizer increased the leaf chlorophyll content,net photosynthetic rate,transpiration rate and stomatal conductance and decreased stomatal limitation(Ls) in the leaf during the late growth stage,and improved the accumulation amount and use efficiency of N,P,and K,and increased pods per plant by 7.1%-36.0%,100-kernel weight by 5.8%-9.7%,pod yield by 17.1%,and total biomass by 3.8% when the slope was 10°,pod yield by 15.7% and total biomass by 15.7% when the slope was 15°.The controlled release fertilizer also improved the protein and fat contents.In addition,when the slope increased,the leaf chlorophyll content,net photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs),the accumulation amount and use efficiency of N,P,and K,pod yield and total biomass under using the two kinds of fertilizers decreased by a certain extent.But the differences for the same fertilizer among different slopes were not significant.
