高海拔旱作地区大葱覆膜密植栽培模式研究

Study on Cultivation Model of Film Mulching and Close Planting of Welsh Onion in High Altitude Arid Farming Area

通过对大葱栽培品种,露地和覆膜、密度等条件对大葱产量和生长情况的影响研究,认为生产中适宜选用株型紧凑、生长速度快、硬杆直立的大葱品种(极晚抽一本、青竹);采用25cm高垄覆白膜(厚度0.01mm)密度(10cm×10cm)的覆膜密植栽培模式是青海2700m左右高海拔旱作地区大葱栽培的最优模式。

Through the study of the effects of cultivated varieties,open field,plastic film mulching,density and other conditions on the yield and growth of welsh onion in high altitude arid area,it is concluded that the welsh onion varieties with compact plant type,fast growing speed and erect hard pole(just as“qingzhu”,“jiwanchouyiben”)were suitable for sellecting in the production.The method of 25cm high ridge mulching 0.01mm thickness white film by 10cm×10cm density planting were the best cultivating patterns of welsh onion in 2700m high altitude dry farming area of Qinghai Province.
