珍珠高粱品种是九十年代我国从西欧引进的一个优良新品种,目前在山西、河南、宁夏、湖南、云南、山东等十多个省(区)试验示范,一般亩产700公斤,高产的突破1000公斤。去年广西的合浦、宾阳等县试种,一般亩产400—600公斤,高产的达800公斤。该品种粗生、适应性广、产量高、用途广,营养成份高,其籽粒蛋白质含量11.8％,比大米高3％;粗脂肪含量2.6％,比大米高0.6％:其秸秆是优质的青饲料,发展珍珠高粱生产对促进粮食生产及畜牧业发展具有十分重要的意义。其栽培技术与种植玉米相似。但其植株较矮,生育期又比玉米少10天左右,所以珍珠高梁的种植密度每亩要达到6000—7000株(比玉米多种2000株)为宜。同时其再生力强,收获第一造后,留头再生,每株留1—2个分蘖苗,通过加强管理,第二造的产量与第一造的产量差不多。
Pearl sorghum varieties is an excellent new variety imported from Western Europe in 1990s. Currently, it has been tested and demonstrated in more than 10 provinces (districts) such as Shanxi, Henan, Ningxia, Hunan, Yunnan and Shandong. The average yield of 700 kg per mu 1000 kilograms. Last year, Hepu and Binyang counties in Guangxi tried their best to plant 400-600 kg of mu per mu and 800 kg of high-yield rice. The coarse varieties, wide adaptability, high yield, wide use, high nutritional content, the grain protein content of 11.8%, 3% higher than rice; crude fat content of 2.6%, 0.6% higher than rice: the straw is a high quality green feed , The development of pearl sorghum production is of great significance to the promotion of grain production and the development of animal husbandry. Its cultivation techniques and planting corn similar. However, the plants are shorter and the growth period is about 10 days less than that of corn. Therefore, the planting density of pearl sorghum reaches 6000-7000 plants per acre (more than 2000 varieties of corn). At the same time its strong regeneration, the harvest after the first made, leaving head regeneration, leaving 1-2 tillers per plant, through the strengthening of management, the second-made production and the first-made production almost.
