To properly intercropping crops, we must follow the following technical principles: High and low and fat and thin with the principle. Such as corn and soybeans, yellow flowers and wheat, the plant growth and development of the two groups of plants are less likely to interfere with each other, and are more conducive to ventilation and light transmission, and promote early maturing and high yield. The principle of combining monocotyledon crops with dicotyledonous crops. Such as corn, sorghum, wheat and soybeans, peanuts, cotton, potato and other collocations, which can be used to cultivate land, but also because of the inconsistency of the depth of its roots and make full use of various layers of soil nutrients, will not be due to a The singular deficiency of one element causes the occurrence of physiological diseases, while at the same time it can increase the overall benefit of the unit area. The principle of habit matching. Some crops in field crops are very bright (such as cotton, wheat, rice), while some crops like shade (such as ginger, buttercups); some crops are drought-tolerant (such as sesame and cotton), and some crops Also like the moist environment (such as rice, leguminous, leafy vegetables), so, according to their respective characteristics, consciously oriented and targeted intensive cultivation, so that they can achieve their own adaptation and satisfaction, so as to obtain Higher yield and unit area benefit than a single plant. The long-term growth period and the short-term intercropping principle. The combination of a longer growing period of the main crop and a shorter growing period of the sub-cropping crops will have less impact on each other and will fully utilize the effective frost-free period in the local area to achieve a high-yield harvest throughout the year. The principles of seeking benefits and avoiding harm. When considering root exudates, it is necessary to seek benefits and avoid hazards based on the relevant effects or different genetic factors. It has been found that the chemical interaction between wheat and peas, potato and barley, garlic and cotton is harmless (or advantageous), so these crops can be matched; instead, rye and wheat, hemp and soybean, buckwheat and corn There are adverse effects between them, they cannot be planted together.
