豫南地区是个老水稻区,历年来紫云英种植面积在水稻种植面积中都占一定比重。近年来,特别是1964年以来,紫云英种植面积有了更大发展,和1963年比较,扩大面积2.6倍多。因此,如何采取措施,在老紫云英区进一步提高单位面积产量,在新紫云英区种好、管好、利用好紫云英,是当前农业生产中的一个重要课题,亦是保证实现稳产、高产农田的一个重要方面。在生产实践中,农民群众对紫云英的栽培和利用,积累了相当丰富的经验,几年来,我们在这方面作过一些调查和试验,现将所得资料整理如下。
Southern Henan Province is an area of old rice. The area planted with asparagus has occupied a certain proportion in the rice acreage over the years. In recent years, especially since 1964, the cultivated area of Astragalus sinicus has been more developed, compared with 1963, expanding the area more than 2.6 times. Therefore, how to take measures to further increase the yield per unit area in the old district of Ziyunying and planted it well in the new district of Ziyunying, how to make good use of Zoysia asiatica is an important issue in current agricultural production and also a guarantee for its realization An important aspect of stable and high-yield farmland. In the practice of production, the peasant masses have accumulated rich experience in the cultivation and utilization of the milk vetch. In the past few years, we have conducted some investigations and experiments in this regard. The information we have collected is as follows.
