陕西省园艺学会、陕西省蔬菜研究所、陕西省铜川市农业局等单位,于1964年10月22日至24日在铜川市联合召开了白菜现场会。 会上陕西省蔬菜研究所介绍了铜川地区大白菜不包心问题的研究结果及其促使包心的主要措施。调查与试验结果指出:铜川地区三十多年来大白菜不包心的原因是由于严重感染毒素病的结果;克服该病危害,促使包心和稳产高产的主要措施是: (1)选择抗病力较强的优良品种:品种试验证明,洛阳大包头白菜抗毒素病力强,且包心好、产量高,在新、老菜区都能种好。包头青麻叶抗毒素病较差,在老菜区不宜种植。但在新菜区则感病病较轻、生长良好,产量仍高。 (2)确定适宜的播种期:试验结果看出,铜川地区播种洛阳大包头,应以立秋前三、四天到立秋后一、二天为宜,其毒素病较轻,包心率及亩产量都高,包心大都紧实,亩产净菜11,621.7斤。包头青麻叶在新菜区的播种时期应以立秋后一、二天为宜。
Shaanxi Horticultural Society, Shaanxi Provincial Vegetable Research Institute, Tongchuan City, Shaanxi Province Bureau of Agriculture and other units, October 22, 1964 to 24 in Tongchuan City held a cabbage scene. At the meeting, Shaanxi Provincial Vegetable Research Institute introduced the research results of the problem of uncoiling Chinese cabbage in Tongchuan area and the main measures to promote it. The results of the investigation and the experiment indicate that the reason why the Chinese cabbage is unwrapped for more than thirty years in Tongchuan area is due to the severe infection of toxins. The main measures to overcome the harm of the disease and promote high yield and high yield are: (1) Strong disease of the elite varieties: breed test proved that Luoyang Baotou cabbage antitoxin strong disease, and good heart, high yield, in the new, old vegetable area can grow well. Baotou green leaf antitoxin disease is poor, in the old vegetable area should not be planted. However, in the new vegetable area, the susceptible disease is lighter, grows well and the yield is still high. (2) to determine the appropriate sowing date: The test results show that Tongchuan sowing Luoyang Baotou, should be three or four days before the beginning of fall to one or two days after the fall of autumn is appropriate, its toxins disease lighter, heart rate and yield per mu High, mostly tight heart package, net yield of 11,621.7 kg per mu. Baotou green leaves in the new vegetable planting area should be established after the fall of one or two days is appropriate.
