芒果滴灌施肥效果研究初报

Primary research on the effect of drip fertilization of mango

通过小区试验,比较了不同滴灌施肥方式及不同施肥用量对芒果产量和品质的影响,结果表明,与沟施肥料全量+浇灌相比,滴灌施肥方式的芒果产量显著增加,增产率为23.5%～31.6%,其中以滴灌施肥量为70%时的效果最好,同时果实品质明显提高,每667 m2增收385元;但沟施肥料+滴灌方式未表现出增产效果,表明滴灌施肥方式提供了最佳的水肥耦合条件,从而达到增产和品质改良的目的。

In the field plot trials, effect of different drip fertilization methods and fertilization amoant on mango yield and quality were compared.Three inigation methods were arranged as furrow application before traditional flooding （as contrast）, furrow application before drip irrigation and drip inigation, two N ,K application rate were arrange as 100% and 70%. The results indicated that, as compared with furrow application ＋ irrigation, drip fertilization could increase yield of mango for 23.5% and 31.6% for different application rate. And the treatment of drip fetilization with 70% fertilization amout had the best effettcts on yield and quality, and the incomes also could be increased by 385 yuan per acre. drip fertilization had the best coupling efficiency of water and fertilizer for plant growth.
