摘要
为探索田家紫皮大蒜返青期高产高效的追肥方式,以当地传统施肥为对照,设置了不施肥、追施高钾复合肥、喷施均衡性叶面肥、喷施高钾型叶面肥4个处理,研究不同追肥方式和肥料对田家紫皮大蒜产量及经济效益的影响。结果表明:与对照相比较,大蒜返青期不施肥会导致植株长势变弱,大蒜显著减产10.53%;喷施绿壮素均衡性叶面肥的大蒜长势及产量变化不大,但有效节约了肥料投入;追施倍硕果高钾复合肥和叶面喷施靓果素高钾型叶面肥的大蒜长势均显著增强,每667m^(2)产量分别显著提高314.97、103.75 kg,每667 m^(2)收益分别高出2 520.24、830.48元;因此,为提高产量及经济效益,应选择在大蒜返青期追施高钾复合肥。
In order to explore the high-yield and high-efficiency topdressing methods of Tianjia purple skin garlic during the regreening stage,taking local traditional fertilazation as control,four treatments were set up,namely no fertilization,topdressing high-potassium compound fertilizer,spraying balanced foliar fertilizer and spraying high-potassium compound foliar fertilizer,and the effects of different topdressing methods and fertilizers on the yield and economic benefits of Tianjia purple skin garlic were studied.The results showed that compared with the control of traditional fertilizer,no fertilization during the regreening stage of garlic would lead to the weakening of plant growth and significantly reduce the yield of garlic by 10.53%.The growth and yield of garlic sprayed with balanced foliar fertilizer 'Lüzhuangsu' had little change,but the fertilizer input was effectively saved.The growth of garlic with high-potassium compound fertilizer 'Beishuoguo' and spraying highpotassium compound foliar fertilizer 'Liangguosu' was significantly enhanced,the yield was significantly increased by 314.97 kg per 667 m^(2) and 103.75 kg per 667 m^(2),respectively,and the income was increased by 2 520.24 yuan per 667 m^(2) and 830.48 yuan per 667 m^(2),respectively.Therefore,in order to improve the yield and economic benefits,high-potassium compound fertilizer should be applied in the regreening stage of garlic.
