Abstract: To achieve high yield cultivation techniques of peanut after garlic harvest, a field experiment on field collocation pattern and density was conducted in Liaocheng Academy of Agricultural Sciences from 2014 to 2015. The split plot design was employed with main plot of field collocation patterns, sub-plot of density. Three field collocation patterns (25, 35, 45 cm) and five densities (single-seed sowing 18×104, 21×104, 24×104, 27×104 plants/hm2 and double-seed sowing 13.5×104 plants/hm2) were set. Effect of field collocation pattern and density on peanut growing characters, yield characters, dry matter accumulation and field transmittance was analyzed. The results showed that the beneficial effect of field collocation patterns A1(25 cm) and A2(35 cm) on field transmittance, pod number per plant, full pod number and pod dry weight was significantly superior to those of A3(45 cm); density had a significant impact on field transmittance, plant dry weight and yield characters. During pod filling stage of peanut, field transmittance of B2(21 × 104 plants/hm2), B3(24 × 104 plants/hm2), B5(13.5×104 plants/hm2) was low, it was conducive to increasing light utility efficiency. A1B3 had the highest yield, which had no significant difference with A1B2, A2B2 and A2B3, but significant difference with other treatments.
