Intercropping methods wheat field “small suet big back” interplanting Pinellia ternata, also known as “two or four” Sui intercalated, that is, in the 6-foot belt field, in the 4- 2 rows of corn on the back. Small row spacing of 1 foot of corn, corn row spacing of 0.5 feet of wheat. After the wheat is harvested, the maize spacing is 5 feet. After the wheat harvest in the maize distance, you can grow two rows of early-maturing soybeans or mung beans. Cultivation and management
