玉米是陇东的主要粮食作物和饲料作物。玉米生产的好坏与丰歉,对全区人民生活和畜牧业的发展均有较大影响。近三十年来,玉米生产发展较快,面积扩大,单产翻番,对解决粮食问题和促进畜牧业的发展起了一定作用。但是与全省和全国相比,仍然是产量低而不稳。其原因是多方面的。据多年来的调查和试验资料证明,主要原因是种植密度偏稀,对雨、热、光能、地力等自然资源的利用不够合理所致。所以,合理密植是陇东玉米生产中的关键问题。
Corn is the main food crops and forage crops in Longdong. The quality of corn production and apology and apology, the development of people’s livelihood and animal husbandry in the region have a greater impact. In the past three decades, the rapid development of maize production, the expansion of its area and the doubling of its output have played a certain role in solving the grain issue and promoting the development of animal husbandry. However, compared with the province and the whole country, the output is still low and unstable. The reason is many. According to years of investigation and test data, the main reason is that the planting density is rather dilute and the utilization of natural resources such as rain, heat, light energy and earthpower is not reasonably enough. Therefore, reasonable density planting is the key issue in the production of Longdong corn.
