向日葵的特性向日葵有广泛的适应性,特别是耐盐碱性较强,在含盐量0.3—0.4%的土壤上可以发芽,生长良好;在不宜种植玉米制作青贮料的土地上可种植向日葵制作青贮料。因此,地处盐碱地区的芦台农场二十多年来,每年播种600—1,000亩向日葵制作青贮饲料。早葵每亩收青体5,000斤左右,晚葵每亩收青体3,000斤左右。土壤含盐量较高的中捷人民友谊农场每年播种20,000—30,000亩做油料,
Sunflower characteristics Sunflower has a wide range of adaptability, especially the strong resistance to salinity, salt content of 0.3-0.4% of the soil can germinate, grow well; can not be planted in corn silage maize land can be planted sunflower production Silage material. As a result, Lutai Farm, located in the saline-alkali region, sows 600-1,000 acres of sunflower per year for silage production for more than two decades. The morning sunflower harvest about 5,000 pounds per mu body weight, sunflower per acre collected about 3,000 pounds of body weight. Zhongke People-Friendship Farm, which has a high salinity of soil, sows 20,000-30,000 mu of oil annually,
