在田间试验条件下研究炭基缓释花生专用肥对花生产量和土壤养分的影响。试验结果表明,施用炭基缓释花生专用肥花生产量明显高于其它施肥处理,增产作用明显,各处理间产量变化趋势为:炭基缓释花生专用肥处理(3808.54 kg hm-2)>NPK处理(3315.27 kg hm-2)>生物炭处理(2844.01 kg hm-2)>CK(1478.74 kg hm-2)。施用生物炭和炭基缓释花生专用肥区,在生育前期有明显的增温作用,土温升高有利于花生出苗,提高了花生的出苗率。炭基缓释花生专用肥施入后土壤中速效氮磷钾含量明显高于施用普通的氮磷钾肥,与普通氮磷钾相比铵态氮和硝态氮含量分别提高了4.8%和13%,速效磷含量提高了9%,速效钾含量提高了4.2%。从产量构成因素分析可以看出,施炭基缓释花生专用肥增产的原因主要是增加单株结果数、出仁率和果重。
Effects of special carbon - based peanut slow release peanut on the yield of peanut and soil nutrient under the field experiment. The results showed that the yield of peanut-specific fertilizer was obviously higher than that of other fertilization treatments, and the yield-increasing effect was obvious. The yield trend of all the treatments was: 3808.54 kg hm-2> NPK Treatment (3315.27 kg hm-2)> biochar treatment (2844.01 kg hm-2)> CK (1478.74 kg hm-2). Application of biochar and charcoal-based peanut slow-release peanut special fertilizer area in the early stage of growth have obvious warming effect, soil temperature is conducive to peanut emergence, increased peanut emergence rate. The contents of available N, P and K in the soil after the application of the special slow-release peanut-based carbon-based fertilizer were significantly higher than those of the conventional NPK fertilizers, and the content of ammonium and nitrate nitrogen increased by 4.8% and 13%, respectively, , Available phosphorus content increased 9%, available potassium content increased 4.2%. From the analysis of yield components, it can be seen that the main reasons for increasing yield of charcoal-based slow release peanut special fertilizer are increasing the number of fruit per plant, the rate of kernel and the weight of fruit.
