在小麦玉米共生期,对二四畦种植方式的气候生态效应与小麦边际效应进行了研究。结果表明,边行小麦在光、温、水、风等方面均有不同程度的优势,反映在边行小麦公顷穗数、穗粒数多,产量高。但与平作相比,边际效应的补偿值小于由于预留玉米带而少种小麦的减产值,最终表现为二四畦小麦略有减产。
During the symbiotic period of wheat and maize, the climatic ecological effects and the marginal effects of wheat on the planting pattern of “Fusifuge” were studied. The results showed that the sideline wheat had different degrees of superiority in light, temperature, water and wind, which was reflected in the number of spikes per hectare, the number of grains per spike and the high yield. However, compared with the flat crop, the compensation for the marginal effect is less than the reduction of wheat output due to the reservation of the corn belt, and the final performance is a slight decrease of wheat yield in the second and fourth trimesters.
