Intercropping is to cultivate more than two kinds of vegetables on the same ground, one after the other, in order to separate each other, interlacing, isolating or mixing and planting. Intercropping is done before planting vegetables or sowing vegetables for later growth. The purpose of intercropping is to increase the multiple cropping index and to arrange the intercropping rationally so that the potential of the land can be brought into full play and the growth of vegetables can be mutually promoted so as to increase the yield and help to achieve balanced supply and diversification of varieties. However, intercropping, such as improper arrangement, the impact of vegetable growth, resulting in losses, for which intercropping, interplanting must have the following principles.
