缓控释肥不同施用量和施用方式对旱作区全膜马铃薯生长及产量的影响
Effects of different fertilization methods and amounts of slow/controlled releasing fertilizer on growth and yield of all-film potato in dry farming areas
摘要
Abstract
In order to investigate the effects of slow /controlled releasing fertilizer on main growth indexes and yield of all-film potato ,three fertilization amounts were designed in a field experiment ,including high level ,medium level and low level fertilizations ,and two irrigation methods ,including furrow fertilization (F) and broadcast application .Main growth indexes and yield of potato were measured .The fertilizer application amount of slow /controlled releasing fertilizer significantly influenced the main growth indexes ,yield and commodity rate of potato .The maximum value of yield ,large tubers and commodity rate of potato with furrow fertilization treatment (HF) were 43 608 .85 kg·hm - 2 ,72 .1% and 92 .7% ,respectively ,when the higher fertilization amount was 900 kg·hm - 2 .The fertilizer application method signifi-cantly influenced the main underground growth indexes ,yield and large tubers of potato .Yield ,large tubers and com-modity rate of potato by the F treatment were higher than those by the B treatment under three fertilization amounts ,and by high fertilization amount ,the yield by the HF treatment was 834 .54 kg·hm - 2 higher than that by the HB treatment , resulting in 6 .4% increase .The fertilization amount × fertilization method did not cast significant effects on all growth in-dexes and yield of potato .In conclusion ,under high fertilization amount (900 kg·hm - 2 ) ,the F treatment should help increase yield of all-film potato in dry farming areas .关键词
