Compared with wheat suits, the summer sowing ridging film can increase max flowering amount of unit plant by 5%, increase its number of fruit threads by 20%, extend the AnM season by 7 days, increase the fructification number of unit plant by 20%, and increase full pods rate of unit plant by 15.8%, as well increase the pod volume by 12.2%. The experimental results illustrated that with proper utilization of climate resource and enhanced scientific management, the negative factors that restrain production such as short growth period and lower full pod rate can be effectively overcome, reaching or surpassing the production and benefits grown with wheat suits. |
