Abstract: In order to effectively solve seeding quantity regulating device applied in big population small individuality no thinning out seedlings of multiple millet cropping with wheat stubble, reduce researching, producing and purchasing costs, and improve seeding efficiency and planting benefit. The technical scheme was designed, applied to small experiment , pilot test and trial production; The seed-metering boxes covered A and B were developed and matching to “Wheat Rotary tillage(no-tillage) sowing and compacting unity machine”, which made of polystyrene foam with advantages of extensive materials, low cost and simple process. The device had characteristics of simple installing and dismantling with “Wheat Rotary tillage (no-tillage) sowing and compacting unity machine”, low production cost, high efficiency and easy operation, and it increased the functions of “Wheat Rotary tillage (no-tillage) sowing and compacting unity machine”.The device accorded with the agro-technique demands of multiple cropping millet of big population small individuality with wheat stubble by application to production demonstration. This study provided technical support of saving cost and easy cultured method for multiple cropping millet with wheat stubble in the Huang-huai wheat producing area.
