我市8、9月份蔬菜供应很不稳定,品种少、质量差、数量严重不足,形成明显的秋淡季。其原因一是夏季高温多雨,不利于蔬菜生长发育而有利于病菌蔓延和害虫滋生。二是耕作制度不够合理,茬口安排比例失调;秋白菜茬口占比重过大,影响秋淡季菜、半夏菜以及晚春恋秋菜的种植面积。特别是一些晚熟品种的茄子、青椒、西红柿也不得不给秋白菜倒茬。这种不合理的现状,既减少了经济收益,又影响了淡季供应,急需设法改进。
In August and September, the supply of vegetables in our city was very unstable with few varieties, poor quality and serious shortage of quantity, forming a clear autumn season. One reason is the hot and humid summer, is not conducive to the growth of vegetables conducive to the spread of bacteria and pests breeding. Second, tillage system is not reasonable enough, crop arrangement of the proportion of imbalance; autumn cabbage stubble share is too large, affecting the autumn and winter dishes, Banxia vegetables and late spring love Autumn vegetables planted area. In particular, some late-maturing varieties of eggplant, green peppers, tomatoes also had autumn stubble. This unreasonable situation has not only reduced the economic returns but also affected the off-season supply, which urgently needed improvement.
