不同覆盖模式与补充灌溉对花生光合特性及干物质积累速率的影响
Effects of different mulching patterns and supplementary irrigation on peanut photosynthesis and dry matter accumulation
摘要
Abstract
[Objective]To study the effects of different mulching patterns and supplementary irrigation on soil water content,dry matter accumulation rate,photosynthesis and quality of peanut.[Methods]Jihua 18(semi-prostrate-type)and Huayu 9610(erect type)peanuts were taken as test materials to set limited irri-gation without film(T1),medium irrigation without film(T2),full irrigation without film(T3),full irrigation with film(T4),then tp analyze the photosynthetic characteristics and quality differences of peanuts under dif-ferent treatments,and finally formulate a suitable combination model.[Results]The soil water content of pea-nut in T4 treatment was the highest.The soil water content of Huayu 9610 in T4 treatment was 3.26%higher than that in T1 treatment at the early growth stage,and that of Jihua 18 T4 was 3.63%higher than that in T1 treatment;under the same treatment,the soil water content of Jihua 18 was higher than that of Huayu 9610.The dry matter growth rate of peanut under T4 treatment was significantly higher than that of other treat-ments.Compared with T1-T3 treatment,the underground growth rate of Huayu 9610 increased by 0.6%,0.5%,0.3%,and the aboveground growth rate increased by 34.4%,17.9%,4.2%respectively at maturi-ty;The underground growth rate of Jihua 18 increased by 1.2%,0.8%and 0.2%,and the aboveground growth rate increased by 54.9%,37.2%and 27.3%,respectively.The protein,oil content and oleic acid content of Jihua 18 were higher than those of Huayu 9610 under the same treatment;All kinds of indexes of Huayu 9610 increased with the increase of water content under no film treatment.[Conclusion]T4 treatment is beneficial to increase soil water content,dry matter accumulation,photosynthetic rate and quality of peanut.However,under the condition of film free cultivation,Jihua 18(semi-prostrate-type)can increase the surface coverage area,reduce water evaporation,and maintain a higher soil moisture content and dry mat-ter accumulation rate compared with Huayu 9610(erect type).The comprehensive property index is better than that of upright peanut.关键词
