平衡施肥对菊花产量的影响

Effect of Different Balanced Fertilization on the Yield of Chrysanthemum morifolium

通过田间试验,研究平衡施肥对菊花产量的影响。结果表明:不同氮素用量影响菊花不同时期干物质和养分的阶段积累量,收获期氮磷钾在不同器官的分配比率不同,各处理菊花的产量差异较大,平衡施肥过程中菊花的氮肥用量为135kg/hm2。

A Field test area, about the impact of N, P, K fertilizers combined application to biological yield. The results showed：Balanced Fertilization can significantly increasing Chrysanthemum morlfolium biological yield, and middling fertilizer is the most appropriate ;Adding N、 P、 K fertilizer can increase absorbed accumulation and the nutrition in Chrysanthemum morifolium growing period, Under Balanced Fertilization on the yield of Chrysanthemum morifolium, the recommendation of N application amount was 135 kg/ha.
