Three-seed type II beanstalk is soft, delicious and nutritious (Table 48). It is a high-quality green feed for livestock, and can also be dried into hay for off-season feeding. The crude protein content of seed is lower than that of soybean (Glycinemax), but higher than that of mung bean (Phasealusradiatus), cowpea and Calbnuscaian, so it is a high-quality concentrate for livestock and poultry. Three-seed-two-type has fast growth speed, tolerance to extensive management and short growth cycle, and can be used as a short-term crop to interplant with sugarcane, cassava and sweet potato. Because of its rapid initial growth, it can be mixed or intercropped with other leguminous grasses with slow initial growth, such as Phyllostachys pubescens and Pueraria lobata. Java, Papua New Guinea and Leucaena. Because the three-seed and two-type beans emerge quickly after sowing, they can cover the soil in a short time, inhibit the growth of weeds, save weeding and obtain a certain yield. Because of its short growth cycle, it will not hinder the growth of subsequent crops. Three-mail type three seeds have economic value and are edible. They are cultivated from south to southwest of Hainan and used to make bean paste, bean sprouts and pastry fillings.
