试验表明，麦垄移栽棉花以中熟品种具有较大的增产潜力；麦垄点播棉花则中早熟和早熟品种产量高。在品比试验的基础上，用中熟品种中棉１９和中早熟品种陕１９８分别进行了不同密度试验，两种种植方式棉花产量都与密度成正相关，麦垄移栽密度应不小于５０００株／６６６．７ｍ２，麦垄点播密度应不小于６０００株／６６６．７ｍ２。 Experiments show that the wheat-ridge cotton transplanting to medium-maturing varieties have greater yield potential; wheat-on-demand cotton is premature and precocious varieties of high yield. On the basis of the ratio test, medium density cultivar Zhongmian 19 and middle early maturing cultivar Shaan 198 were tested with different densities respectively. The cotton yield of both planting methods had a positive correlation with the density. The transplanting density of wheat mats should not be less than 5000 /666.7m2, ridges on demand density should not be less than 6000 /666.7m2.
