在无霜期仅有90多天的高寒地区,不仅可以栽培元葱,而且可以获得稳定高产。海拉尔市良种场已有7～8年的栽培历史,一般田亩产4,000～5,000斤,高产地块可达7,000～8,000斤。高寒地区元葱高产栽培的技术要点是:1.选用高产品种,培育壮苗。无霜期短的高寒地区,每年只可栽培一茬元葱,为夺高产,应选用中晚熟品种,早熟品种不易获得高产。以选用大同地区繁育的紫皮元葱品种为适宜。每亩用种量为6两。占用育苗床面积10平方米。温室育苗3月15～20日播种。温床育苗3月25日～4月1日播种。适当早播、稀播,中后期进行低温锻
Frost-free period of only 90 days in the alpine region, not only can cultivate Yuan-yuan, but also to obtain stable and high yield. Hailar city has seven to eight years of cultivation history of the field, the average field yield 4,000 to 5,000 pounds, high-yield plots up to 7,000 ~ 8,000 pounds. Alpine green onion cultivation techniques of high yield points are: 1. Selection of high-yielding varieties, nurturing strong seedlings. Frost-free period of the alpine region, only a year to cultivate a crop of onion, in order to win high yield, should be used in the late-maturing varieties, precocious varieties not easy to obtain high yield. In order to choose the breeding of purple skin Yuanchuan Datong varieties suitable. The amount of used per acre is 6 two. Occupation nursery bed area of 10 square meters. Greenhouse nursery March 15 to 20 sowing. Seedbed nursery March 25 ~ April 1 planting. Appropriate early sowing, thin sowing, in the late forging
