| Abstract: | The intercropping pattern could also increase economic benifits while getting high yield of wheat,early-grown corn and summer-grown corn The output value and net income reached 27045.9 yuan/hm2 and 14884.95 yuan/hm2, the output value in-creased by 91. 5% and 20.38% and net income by 74. 70% and 11. 81% than that of monocropping spring corn and wheat-corn sequencial cropping pattern According to the difference of time and space at stages of crop growth and development, the output value and net income could be further increased by multiple intercropping and relay in-tercropping with overwatering spinach and early mature Chinese cabbage. |
