Applied Research of Water and Fertilizer Integration Technology on Garlic

摘要

Garlic (Allium Sativum L.) is a favorite vegetable that is widely cultivated around the world. Traditional ditch irrigation and ground fertilization have many drawbacks, but the advantages of water and fertilizer integration are obvious. In order to study the effect of different irrigation and fertilizer treatments on the yield in a garlic field, the main garlic variety "er shui zao" in Dangyang city was used to be observed and compared the yield of garlic sprout and garlic bolt with different water and fertilizer integrated equipment and different fertilizer structures. Compared with the ditch irrigation treatment, irrigation water and fertilizer applications were reduced by 51.56% and 38.00% respectively both in the semi-fixed micro sprinkler irrigation treatment and mobile micro spray irrigation treatment throughout the growth cycle, but evident increase of the yields were found. The yields of garlic sprout and garlic bolt could reach 3845.56 kg/667m~2 and 1010.45 kg/667m~2 respectively in the treatment of semi-fixed micro-sprinkler irrigation combined with the leaf-specific water-soluble fertilizer. It could increase production and efficiency, and improve the water-fertilizer utilization ratio and mitigate the environmental contamination, achieving the production goal of saving costs and increasing profits.
