杂豆具备耐旱、耐瘠、耐阴等特性,既能单种,又能和高粱、玉米等高稈作物进行混作、套种,在肥地瘦地都能种植,并有培养地力的作用。特別是杂豆播种期幅度較宽,生育期较短,抗逆性强,是比較理想的救荒作物。它不仅在旱地輪作換茬中占有一定地位,而且还是某些易旱地区水田布局上重要的預备作物。因此,杂豆栽培的面积,各地都占有一定的比重;以安徽省而言,每年即約有七、八百万亩之多。但由于杂豆不是主要作物,容易为人忽視,以致生产上应用的品种,大多良莠不齐,混杂严重,有些名貴品种几濒于絕迹;另一方面,又由于資料缺乏,无所依据,給引种造成困难。为此,我們認为整理研究杂豆地方品种,乃
Zadou has the characteristics of drought tolerance, barren resistance, shade tolerance and the like, and can both be mixed with high-stalk crops such as sorghum and corn, and can be planted and planted in thin and fertile land, with the function of cultivating fertility. In particular, the wide range of hybrid beans sowing period, shorter growth period, resistance is strong, is an ideal savior crop. Not only does it occupy a certain place in dryland rotation, but it is also an important preparatory crop for paddy fields in some drought-prone areas. As a result, the area of hybrid beans occupies a certain proportion in all regions; in terms of Anhui Province, there are about seven or eight million mu each year. However, due to the fact that Zadou is not a major crop, it is easily neglected. As a result, most of the cultivars used in production are mostly mixed with each other in a mixed way. Some rare species are near extinction; on the other hand, they are also difficult to be introduced because of lack of information . To this end, we think finishing the study of local varieties of beans, is
