摘要
为探索生姜化肥减量施肥技术,在田间试验条件下,设置不施肥(CK)、100%化肥(T1)、90%化肥+4500 kg·hm^(-2)生物有机肥(T2)、80%化肥+5400 kg·hm^(-2)生物有机肥(T3)、70%化肥+6300 kg·hm^(-2)生物有机肥(T4)处理,研究不同施肥方式对生姜产量和品质的影响。结果表明,化肥减量10%~30%配施一定量的生物有机肥能够显著提高生姜产量。其中,T3生姜产量最高,较T1显著增产37.55%。与单施化肥相比(T1),化肥减量配施生物有机肥处理提高了生姜可溶性糖、维生素C和挥发油含量,显著降低了生姜粗纤维和硝酸盐含量。其中,T3处理的可溶性糖和维生素C含量最高;T4处理的挥发油含量最高,粗纤维和硝酸盐含量最低。各处理生姜蛋白质含量高低依次为T1>T2>T3>T4>CK。经隶属函数法综合评价,化肥减量20%配施5400 kg·hm^(-2)生物有机肥(T3)处理效果最好,是实现生姜优质高产栽培的良好施肥模式。
Field experiment was conducted to seek effective measures to reduce chemical fertilizer in ginger production.The treatments included zero fertilizer(CK),100%chemical fertilizer(T1),90%chemical fertilizer plus 4500 kg·hm^(-2) microbe-organic fertilizer(T2),80%chemical fertilizer plus 5400 kg·hm^(-2) microbe-organic fertilizer(T3),70%chemical fertilizer plus 6300 kg·hm^(-2) microbe-organic fertilizer(T4).The results showed that the reduction of chemical fertilizer by 10%to 30%combined with microbe-organic fertilizer significantly increased the yield of ginger.The yield of T3 treatment was the highest,37.55%higher than that of T1 treatment.The treatments with reduced chemical fertilizer combined with microbe-organic fertilizer increased the contents of soluble sugar,vitamin C and volatile oil,and significantly reduced crude fiber and nitrate in ginger.Ginger soluble sugar and vitamin C content were the highest for T3 treatment.T4 produced ginger had highest volatile oil and lowest crude fiber and nitrate.Ginger protein content for different treatment was T1>T2>T3>T4>CK.Based on the results of this experiment we recommend a reduction of 20%chemical fertilizer combined with 5400 kg·hm^(-2) microbe-organic fertilizer for high-quality and high-yield ginger production.
