氮肥管理与根瘤菌接种模式对花生生长、氮吸收利用及产量的影响
Effects of nitrogen fertilizer management and rhizobium inoculation methods on growth, nitrogen uptake and yield of peanut
摘要
Abstract
To explore cultivation technology for high-yielding and high fertilizer-nitrogen (\N) use efficiency for peanuts in shajiang black soil area, a field experiment was conducted to study the effects of N fertilizer management and rhizobia inoculation methods on peanut growth, N uptake and yield. The results indicated that N application increased SPAD value of peanut leaves, effectively promoted the growth of peanuts, and significantly increased the N use efficiency and yield of pods. Under the same rhizobium methods (\rhizobia seed dressing or applying to soil), the first branch length, number of total branch, number and weight of full fruit per plant, 100-pod weight, N use efficiency and yield were recorded at 50％ N as basal fertilizer and 50％ N topdressing at flowering stage, and100％ N as basal fertilizer treatment. The efficiency of these treatments were significantly higher than those of 50％N topdressing at flowering stage and 50％ N topdressing at pod setting stage, indicating that high-yielding and high N efficiency of peanuts required a certain N fertilizer rate in the early growth stage. Compared with two inoculation methods of rhizobia seed dressing and N application to soil, rhizobia seed dressing with N fertilizer had a better effect on peanut yield, but no significant difference between two inoculation methods. In the shajiang black soil area of southern Henan Province, the 50％ N as basal fertilizer combined with a 50％ N fertilizer topdressing at flowering stage with rhizobium seed dressing was a better methods for peanut production.关键词
