43个土壤基础地力测定汇总,当季小麦土壤基础地力供应氮(N)83.1 kg/hm2、磷(P2O5)36.75kg/hm2、钾(K2O)48.15 kg;12个点的测定结果,100 kg小麦籽粒产量平均吸氮(N)2.75kg、磷(P2O5)1.04 kg、钾(K2O)1.84 kg;小麦全期对肥料养分的吸收率钾>氮>磷。水稻土和潮土氮肥吸收率分别为48.31%、39.26%,磷肥(P2O5)分别为28.79%、39.57%,钾肥(K2O)吸收率分别为50.30%、41.05%。
According to the results of 43 soil foundation measurements, the seasonal soil available nitrogen (N) 83.1 kg / hm2, phosphorus (P2O5) 36.75 kg / hm2 and potassium (K2O) 48.15 kg; The average grain yield was 2.75kg N, 1.04kg P2O5 and 1.84kg K2O, while the absorption rate of fertilizer and nutrients to potassium> N> P in wheat during the whole period. The absorption rates of paddy soil and alluvial soil nitrogen were 48.31% and 39.26%, P2O5 was 28.79% and 39.57%, respectively. The K2O absorption rates were 50.30% and 41.05% respectively.
