1. Plant type should be “high-dwarf†and “fat-thinâ€. That is, tall straw crops and dwarf crops are matched; crops with loose planting and lateral growth of branches and leaves are matched with crops with compact plant types and longitudinal growth of branches and leaves to form a composite group with good ventilation and light transmission. Such as corn and potatoes, sorghum and soybeans. 2. The leaf type should be "-tip-circle". That is, round-leaved crops (such as cotton, sweet potatoes, soybeans, etc.) are matched with sharp-leaved crops (such as wheat, corn, sorghum, etc.) to make full use of soil nutrients and moisture. 3. The root system must be "deep-shallow". That is, deep-rooted and shallow-rooted crops are used to make full use of nutrients and moisture in the soil. 4. Adaptability to "-yin-yang", "- wet-dry." That is, the shade-tolerant crops are matched with drought-resistant crops. This will be beneficial to each other's ability to adapt to the special environment in the compound population, reduce droughts and floods, stabilize production and security. 5. The fertility period should be “—early to lateâ€. That is, the maturity period of the main crop should be later, and the maturation period of the sub-crops should be earlier, in order to facilitate the harvest and sufficient light for the main crop to create high yields later in the crop. 6. The density must be "large-small" and "wide-narrow". That is, the density of the main crop is larger and the width of the crop is wider; the density of the secondary crop is smaller and the species is narrower. In order to ensure the advantages of crop yield increase, both main and subsidiary crops will be harvested.
