很多文献资料报导了向日葵具有耐盐、抗寒、抗旱,种植后可减轻土壤盐碱危害的特性,适宜在盐碱地种植。辽宁、山东等省在盐碱土上种植向日葵获得了较大的收益,如地处黄河故道的渤海农场,1980年起利用盐碱地种向日葵,连续二年丰收,1981年扩种6000多亩向日葵,总产50多万斤,收入40万元。我所,地处杭州湾西部的海涂土壤上,1979年开始从黑龙江省引种苏油一号北方种向日葵进行春秋播试验,两季平均亩产400~500斤,可收入200~250元。
Many literatures reported that sunflower has the characteristics of salt tolerance, cold resistance, drought resistance and can reduce the damage of soil salinity after planting, and is suitable for planting in saline-alkali soil. Liaoning, Shandong and other provinces have benefited greatly from the planting of sunflowers on saline-alkali soil such as Bohai Farm in the old course of the Yellow River. From 1980, the use of saline-alkali land to sunflowers has been bumper for two years in a row. In 1981, the plant expanded to more than 6,000 mu of sunflower, Producing more than 50 kilograms, income 40 million. The institute is located on the tidal flat soil in the west of Hangzhou Bay. In 1979, we started to plant spring sun and sowing the northern sunflower in Suyou No.1 from Heilongjiang Province. The average yield per mu in the two seasons was 400-500 jin and the income was 200-250 yuan.
