水肥供应对谷子品种晋谷29产量及经济效益的影响

摘要

试验主要探讨适合陕北地区旱地谷子增产增效生产的科学配方施肥标准,进而大面积示范推广.结果表明,水肥供应对谷子产量及经济效益有显著的影响;在谷子作物上化肥配施和灌溉都能显著增加经济效益,但施肥不合理或干旱少雨情况下经济效益均有所下降;配方施肥(FF)处理的地上部生物量和产量均为最高,分别为27 535.16,3 440.63 kg/hm2,所有配方施肥处理的地上部生物量及产量均分别比相对应的常规施肥处理显著提高14.77％～22.22％和3.50％～9.43％;所有施肥处理的产量均高于不施肥(CK)处理;从经济效益来说,羊粪36 000 kg/hm2(M3)处理有利于提高晋谷29的产量,净收益最高.%This experiment mainly discussed the scientific formula fertilization standard,which was suitable for increasing yield and increasing efficiency of dryland millet production,and then there was a big demonstration.The result showed that the supply of water and fertilizer had a significant impact on grain yield and economic benefits.The economic benefits of fertilizer combination and irrigation significantly increased in millet,but the economic benefits were decreased with unreasonable fertilization or less rainfall.The highest of the aboveground biomass and yield under the formula fertilizer (FF) were 27 535.16,3 440.63 kg/hm2,respectively.The biomass and yield of all the formula fertilizer treatments significantly increased by 14.77％-22.22％ and 3.50％-9.43％ to the corresponding conventional fertilizer treatment,respectively.The yield of all fertilizer treatments were higher than that of no fertilizer (CK).In terms of economic benefit,the treatment of sheep manure 36 000 kg/hm2 (M3) was beneficial to increase the yield of Jingu 29 and therefore the income was increased.
