此区长期以来大豆多种植在边远瘠薄地上,不施肥、不耕翻、不治虫,品种很少更新,多种植当地的农家种,对优良品种需求不迫切,如沁县、武乡、壶关、长子、襄垣等还种植着当地的小黄豆。播期从4月20～5月20日长达一个月,因而产量水平很低。据在沁县南里乡调查,当地农民没有见过亩产150公斤的大豆,最多亩产100多公斤。据在襄垣、武乡等地考查,当地农民从未对大豆治过虫,栽培技术十分落后,如能进行关键性的改进,产量将有很大提高。
This area has long been planted in the remote and infertile soybeans on the ground, not fertilizing, not plowing, pest control, species rarely updated, planting more local farmers, the demand for fine varieties is not urgent, such as Qinxian, Wuxiang, pot off , Eldest son, Xiangyuan also planted the local small beans. Sowing date from April 20 ~ May 20 up to a month, so the yield level is very low. According to a survey conducted in Nanli Township of Qinxian County, the local peasants have not seen the 150-kg-per-mu yield of soybean and the maximum yield of more than 100 kg per mu. According to surveys in Xiangyuan and Wuxiang, local peasants have never managed to cure pests of soybean and the cultivation technology is very backward. If key improvements can be made, the output will be greatly increased.
