摘要
意大利黑麦草是我站1974年引种、选育、栽培进而推广的一个高产优质的一年生禾本科牧草。该草种喜温、喜湿。在江西9～10月播种,平均株高100厘米左右,种子于6月上中旬成熟。全生育期220～260天。该草有以下优良农艺特性:1、适应性广,抗逆性强,耐寒、耐酸、抗病虫害。2、产草量高,该品种分菜力强,再生性能好,年可刈割3～5次,亩产鲜草0.5～1.38万公斤。3、草质好,其茎叶柔嫩多汁,适口性很好。据我站化验,粗蛋白质含量为8～17％。从1979年起,该草种推广到全国各地,各场、专业户、农户用以养牛,鱼、猪、羊、免及禽等,均取得显著经济效益。说明意大利黑麦草是一种大有推广前途的草种。
The first part on this paper presents the Italian ryegrass, an annual gramineae herbage, introduced by our centre in 1974. After thorogh our breeding, culturing and extending this ryegrass has possessed high yield and quality. It is thermophile and ombrophilic, sowed about September—October, and harvested in first twenty day period of June of coming year. Average plant height is about one hundred centimeters. The ryegrass shows following agronomic characters: 1. broad adaptiveness and advers resistance: It shows cold endurance, acidity resistant, infertile soil tolerance, and pest resistant. 2. high fresh yield; It has a strong tillering and regenation abilities. Its cutting frequancy is about 3-5 times every year: Fresh yield is about five thousand to thirteen thousand eighe hundred kilogrammes per mu. 3. high fresh quality: Its pliable stemes and leaves are filled with sap. According to our experiment, the contences of crude protein is about 8-17 percent: The second part, the Italian ryegrass had been extended to all our country in 1979, since then many farms and peasants used the ryegrass as the foods of neat, fish, pigs, sheep, rabbits and fowts, and appeared many typied examples of economic benefit: These examples indicate that the ryegrass has a vast vistes for extending further.
