66—25箭舌碗豆(Vicia Sativa)与苕子同属。1972年秋,我场从江苏省农科所引进了这个品种,经过了两年的试种,初步认为该品种有耐迟播、早熟、根系发达、结籽多、肥效高的特点,每亩可收籽200～250斤,鲜草产量3000～4000斤,每千斤鲜草茎叶含氮4.5～5.3斤,含磷2.3～2.6斤,代替蚕豆作后季稻茬口的绿肥,可以节省蚕豆的用种。但它的耐盐性不强,一般含盐量0.15%以下的土壤才能种植,鲜草产量也比蚕豆和草头低些。现将66—25箭舌碗豆的栽培方法介绍
66-25 Vicia Sativa belongs to the same genus. In the autumn of 1972, I introduced this variety from Jiangsu Provincial Agricultural Science Institute. After two years of trial planting, it was preliminarily thought that the variety had characteristics of delayed sowing, early maturity, developed root system, high seed yield and high fertilizer efficiency. Seeds 200 to 250 pounds, fresh grass yield 3000 to 4000 pounds per kilogram of fresh grass stems and leaves containing 4.5 to 5.3 kg of nitrogen, phosphorus 2.3 to 2.6 kg, instead of fodder for the post-season stubble of green manure, you can save the use of broad beans Species. However, its salt tolerance is not strong, generally less than 0.15% salt content of soil can be planted, fresh grass yield lower than the beans and grass head. The introduction of the method of cultivation of 66-25 bowls of beans
