地膜覆植粮食作物及瓜果,蔬菜已全。推广、应用,对提高单位面积产量,减少中耕、节约用水,有效的利用土壤养分和改良土壤理化性状成效显著。但在畜牧业生产中仍属空白。据我站多年来对“山西多穗青贮玉米”、“美国青贮玉米”,“156玉米”及“英—58青贮玉米”四个品种栽培筛选,认为“英—58”其种籽及(青草秸秆和果穗)均表现出显著的增产性能。缺点在于生长季较长,属晚熟种。因奇台地区无霜期偏短,年积温偏低,是影响玉米产量和经济效益的重大原因。为提高地温,保证“英—58玉米”在整个生产中缩短籽粒成熟周期,减少自然灾害的影响,特

Promotion, application, to improve yield per unit area, reduce cultivation, water conservation, effective use of soil nutrients and improve the physical and chemical properties of soil remarkable results. However, it is still blank in livestock husbandry production. According to my station over the years, “Shanxi more spike corn”, “American silage corn”, “156 corn” and “British -58 silage corn” four varieties of screening, that the “British -58” its seeds and Straw and ear) showed significant yield increase. The disadvantage is that the longer growing season, is a late-maturing species. Due to the short frost-free period and low annual accumulated temperature in the Qitai area, it is a major reason that affects the corn yield and economic benefits. To improve the ground temperature, to ensure “British -58 corn” in the entire production to shorten the maturity of the grain and reduce the impact of natural disasters, special
