甘蔗是重庆市三江(即涪江、嘉陵江、长江)沿岸主要经济作物,近年来因农产品调价,而蔗、糖价格偏低,蔗农收益减少,严重地影响了种蔗积极性。为了增加蔗地收益,提倡于蔗行内间套矮生早熟作物。为了解决甘蔗与间作物争光、争肥的矛盾,将甘蔗(窄行距)等行植蔗改为宽窄行种植,在宽行内间种矮生作物,但为了进一步探索甘蔗种植密度和间种不同作物,对甘蔗产量和 Sugarcane is a major cash crop along the coasts of Sanjiang (ie, Fujiang River, Jialing River and Yangtze River) in Chongqing. In recent years, sugar cane and sugar prices have been lowered due to the price adjustment of agricultural products, while the profitability of sugarcane farmers has been reduced. This has seriously affected the enthusiasm of sugarcane. In order to increase the yield of sugarcane field, it is recommended to plant the dwarf and early-maturing crop in the cane line. In order to solve the conflict between sugarcane and interspecies competition, the sugarcane (narrow row spacing) and other rows of sugarcane were changed to narrow and narrow row planting, interspecific dwarf crops within wide rows, but in order to further explore the sugarcane planting density and intercropping different crops , On the production of sugar cane and
