风沙地有机无机肥配施对花生光合生理特性及产量影响
Effects of Combined Application of Organic and Inorganic Fertilizers on Photosynthetic Physiological Characteristics and Yield of Peanut in Sandy Soil
摘要
Abstract
In order to study the effects of organic fertilizers, diammonium phosphate and potassium sulfate on photosynthetic physiological characteristics and yield of peanut in sandy soil,Four treatments with different fer-tilizers and a no fertilizer control were designed to study the effects of different fertilizers on leaves physiological characteristics and yield of peanut.The result showed that:the peak photosynthetic rate and transpiration rate of peanut leaves under different fertilizers were all appeared at about 12:00 p m,at this time, the photosyn-thetic rate and transpiration rate of T 4were the highest at 22.42 μmol/m2· s,9.84 mmol/m2· s,respective-ly,which was significantly higher than other treatments.The LAI and SPAD values of T4were also at a high level during the flowering period and the full-length period,and the maximum value of the LAI and SPAD were 5.2 and 42.8,which significant different with T CK.The number of branches,fruits per plant,the productivity per plant,the fruit weight per shucks, and 100-kernels weight were better than those of T CK.The order of yield was T4>T2>T3>T1>NCK,and the yield of T4was 272.8 kg/667m2,which was significantly higher than other treatments.The lowest yield was T CKof 180.6 kg/667m2.All proved that the organic and inorganic fertilizers could be used to regulate the soil nutrient balance in the sandy soil,protect the normal photosynthet-ic function of peanut and finally improve the crop yield.关键词
