A method for culturing the black bean includes such steps as planting mung bean, red bean and black soybean in a same field line by line at intervals in the first year, harvesting and storing the mung bean, planting the mung bean in the second year, artificial pollinating by the pollen of black soybean for hybridizing, planting the hybridized mung bean in the third year, and artificial pollinating by the mixture of the pollens of honeysuckle flower, Chinese thorowax and divaricate saposhnikovia to obtain black bean. Its advantages are high medical and edible values and rich nutrients including protein, raw fat, VC, VB2 and trace elements.

The invention relates to the field of corn breeding, in particular to a corn hybridization pollination leaf rotating and folding female spike bagging method and a pollination method. The corn hybridization pollination rotary folding leaf female spike bagging method comprises the following steps: rotating and folding a part, with the distance 15-20 cm from a spike position leaf to the base part of the leaf, of the spike position leaf, and fixing the leaf end part of the spike position leaf at the intersection position of the next leaf on the same side and the stem; bagging the rotating and folding position of the spike position leaf and the tip of the female spike jointly. By the method, a paper bag is tightened by tension generated by that the rotated spike position leaf recovers to the original shape, and the sleeved bag is form and not liable to loose, slide and remove; damage to the leaf is avoided. Pollination, which is conducted after bagging is conducted by the method, is very simple and convenient to operate and is quick and efficient, the technology is simple and easy to master, the bagging efficiency is increased by more than six times, the pollination efficiency is increased by more than 5 times, the foreign pollen pollution ratio is reduced by more than 15%, the traditional fixing process is avoided, the material articles and the labor expense of bagging and pollination are saved, the cost is obviously reduced and the method is very easy to popularize and apply.
