The maximum output of corn kernels of early matured maize sown in spring reached 8 820.0 kg/hm2. The maximum output of direct seeding late japonica rice reached 7 722.0 kg/hm2. The minimum output of kernels of two crops in two seasons reached 15 165.0 kg/hm2. It is proposed that the growth period of early spring matured maize should be controlled within 120 days from March 20（sowing） to July 20 （ripening） with accumulated temperature of 2 600 ℃. The growth period of late japonica rice varieties should be controlled within 100 days with accumulated temperature of 2 360 ℃. The crops are direct seeding with stubble on July 20, full heading around September 17 and ripened before the end of October.

The results indicated that, compared with the local traditional patterns, the unprocessed food grain yield of new planting pattern of double cropping that broad bean-organic sweetpotato was decreased by 78.47%~84.08%, but the total output value of that were increased by 36.61%~49.46%, net output value of that were increased by 65.67%~87.38%, net benefits of that were increased by 3.64~4.64 times than control, agriculture labour net productivity of that were increased by 1.01~1.27 times. It can be seen that the new pattern of broad bean-organic sweetpotato has a good prospect in popularization and application in Xichong county and other similar regions.
