随着农村产业结构的改革,养殖业有了较大发展,对饲草的需求日趋增多。为了提高饲草的产草量,延长利用期,必须进行合理的收割。从1983年秋至1985年冬,我们对适合沿海地区生长的法斯克草(牛尾草)、鸡脚草(鸭茅)、紫花苜蓿和黑麦草(意大利黑麦草)等饲草的收割次数、时间及肥水管理等进行了观测与试验。 试验在滨海盐土上进行,土壤氯化钠含量在0.1~0.15%之间,肥力较低,有机质含量1%左右,速效磷5ppm左右,土质为粉砂壤土。9月中旬播种,每亩用种量,法斯克草2斤,鸡脚草2斤,紫花苜蓿1.5斤,黑麦草2斤。
With the reform of rural industrial structure, aquaculture has made great progress, and the demand for forage grass is increasing day by day. In order to improve the forage production and prolong the period of utilization, reasonable harvesting must be carried out. From the autumn of 1983 to the winter of 1985, we compared the number of forage harvests, such as Fischschild grass, Prunella sibirica, alfalfa and ryegrass (Italian ryegrass) suitable for coastal areas and Fertilizer and water management conducted observations and experiments. The experiment was carried out on coastal saline soil with soil sodium chloride content of 0.1-0.15%, low fertility, organic matter content of about 1% and available phosphorus of about 5 ppm. Soil was silty loam soil. Seeding in mid-September, per acre with the amount of 2 kg Fisk grass, chicken feet grass 2 kg, 1.5 kg alfalfa, 2 kg ryegrass.
