我省淮北地区是夏大豆主要产区,但目前单产较低,限制着大豆生产的发展。1983～1985年在淮北夏大豆产区的灌云县,我们进行了万亩夏大豆亩产150公斤的栽培技术研究,总结出了相应的一套栽培模式。1985年示范推广面积达20万亩,平均亩产115公斤;其中,试验区1.14万亩单产达157.9公斤,创本区夏大豆大面积单产最高水平。本文就三年研究结果,对夏大豆亩产150公斤的生育形态指标及栽培模式进行总结。这一技术适于苏、皖、鲁、豫黄淮夏大豆区推广应用。
Huaibei Province is the main producing area of summer soybean, but the current low yield limits the development of soybean production. In 1983 ~ 1985 in Huaiyun summer soybean production area of Guanyun County, we conducted a mu of summer soybean 150 kg per mu cultivation techniques, summed up a corresponding set of cultivation patterns. In 1985 demonstration area of 200000 acres, an average yield of 115 kilograms; of which, the test area of 11400 acres yield 157.9 kilograms, the highest yield area of summer soybean the highest level of large-area yield. In this paper, the results of three years, the yield of 150 kg per mu yield of summer soybean morphological indicators and cultivation patterns are summarized. This technology is suitable for Jiangsu, Anhui, Shandong, Henan Huanghuai summer soybean area to promote the application.
