玉米是在小麦、水稻之后的世界三大谷物。玉米在陕北地区谷物种植中占的比重较大。陕北地区土地资源广阔,光照充足,具有广阔的种植前景。近年来,由于玉米秸杆青贮技术的广泛使用,给陕北地区畜牧业发展特别是奶牛养殖业注入了新的活力。所以,玉米的产量和秸杆的生物产量成了试验研究的主要问题。在现有条件下,采取一定的技术措施,提高玉米的种植密度,提高玉米的产量和秸杆生物产量,是促进农民,特别是种养殖业户增收的有效途径。
Corn is the world’s three major cereals after wheat and rice. Corn accounts for a larger proportion of cereal crops in northern Shaanxi. The land resources in northern Shaanxi are vast and have plenty of light and have broad planting prospects. In recent years, due to the extensive use of corn straw silage technology, it has injected new vigor into the development of animal husbandry in northern Shaanxi, especially dairy farming. Therefore, the yield of corn and the biological yield of straw have become the main problems of experimental research. Under the current conditions, adopting certain technical measures to increase the planting density of maize and increase the yield of maize and the biological yield of straw is an effective way to increase the incomes of peasants, especially breeding farmers.
