The invention relates to the technical field of agricultural planting, in particular to a multi-
cropping compound planting method which is suitable for areas with abundant hydrothermal resources and aims at solving the problems that in the prior art, three-dimensional
collaboration is lacked, green and fresh products are single, the
straw utilization rate is low and scene compatibility is poor. According to the method, a vertical, transverse and vertical three-dimensional
system is built with one year as a cycle and fresh corn as a frame, and a 420 cm standard planting unit is arranged: 360 cm wide
naked barley is sown in autumn, and 60 cm wide
naked barley is reserved for winter turning and spring cultivation; fresh corn and green soy beans /
hyacinth beans are interplanted in the next spring, and the corn is wound to serve as a
vine climbing support before being harvested; covering with
naked barley straws in summer, and
intercropping green soy beans and peanuts;
sowing peas in late autumn and harvesting green pods. Straws are fully utilized in the whole process, and six types of fresh products are supplied all year round. According to the method, large-scale and scattered planting is considered, the farmland
utilization rate and the farmer income are improved, the farmland
biodiversity can be enhanced, the
cultivated land fertility is improved, and the
ecological agriculture requirement is met.
