Effects of Different Planting Modes on Peanut Photosynthetic Characteristics, Leaf Area Index and Yield in the Sandy Area

摘要

Five planting modes were designed to study photosynthetic characteristics, leaf area index and yield of peanut variety as Fu Hua 17 in order to provide theoretical basis for peanut yield increase in the sandy area. Results showed that the mode of peanuts planted for double rows in the border check with mulched drip irrigation (T1) was the best. The second was the mode with single grain planted and staggered for double rows in the bare ridge (T2). The order for the yield from the highest to the lowest for the five modes was: those planted for double rows in the border check with mulched drip irrigation (T1) > those with single grain planted and staggered for double rows in the ridge (T2) > those planted and densified in the narrower ridge (T3) > those planted for three rows in the border check (T4) > those as normally planted in the bare field (CK). Therefore, the planting mode of double rows in the border check with mulched drip irrigation (T1) and the mode of single grain planted and staggered for double rows in the bare ridge (T2) were better for the sandy area.
