近年来，青花菜在我国栽培面积不断扩大，种子需求量不断增加。由于目前生产用种多为杂交一代，而青花菜杂交制种技术性强，往往因栽培技术等原因引起杂交制种产量低而不稳，难以满足生产需求，为此进行了不同播种期和不同割球方式等方面的探讨，现将试验结果报告如下。1材料与 In recent years, the growing area of ​​broccoli in China continues to expand, increasing the demand for seeds. Due to the current production of mostly hybrid generation, and broccoli hybrid seed production is strong, often due to cultivation techniques and other causes hybrid seed production is low and unstable, it is difficult to meet production needs, for which the different sowing and cutting Ball way and so on, now the test results are reported as follows. 1 material and
