象草又名紫狼尾草(Pennisetum purpureumSchum),禾本科狼尾草属,原产非洲,系多年生丛生高大草本。茎秆直立,叶片狭长茂盛,分蘖和再生能力强,营养近似青玉米,是一种高产优质青饲料。 1980年我们从江西引入象草,试种2.5亩。试验田为砂壤土,部分砂土。3月24日开窖取出种茎种植,行距50厘米,沟深约9厘米。全茎双株排列种植,4月18日出苗。1个月后迅速分蘖,6月中旬开始割青,全年割青4~5次,每亩共收鲜草11151斤。从试种结果看,象草在上海地区适应性广,耐旱、耐劳,利用时间长,易种、易管、繁殖快,产量高,与其他冬春青饲料搭配种植,可为奶牛提供更多的青饲料。种好象草,可参考以下措施: 1.抓早、全苗。注意播种质量,及时移苗补缺,力争延长其生长期。充分利用高温季节,增加
Grass, also known as Pennisetum purpureum Schum (Grass), grass Pennisetum, native Africa, Department of perennial tall tall herbs. Stems upright, long and luxuriant leaves, strong tillering and regeneration ability, similar to green corn nutrition, is a high yield and quality green feed. In 1980, we introduced weeds from Jiangxi and planted 2.5 mu. Experimental field for sandy loam, part of the sand. March 24 opened the pit to remove the planting stems, spacing 50 cm, ditch depth of about 9 cm. The whole stem double plant arrangement, April 18 emergence. 1 month after rapid tillering, mid-June began cutting green, cut 4 to 5 times a year, a total of 11,151 pounds per acre fresh grass. From the results of trial planting, grass weed in Shanghai area has wide adaptability, drought tolerance, long-term use, easy to grow, easy to manage, fast propagation and high yield, and other winter and spring forage with planting, can provide more for cows Green fodder Kind of grassy, may refer to the following measures: 1. catch morning and whole seedlings. Pay attention to sowing quality, timely replacement of fill vacancies, and strive to extend its growing season. Make full use of high temperature season, increase
