硼、钼是植物正常生长发育所不可缺少的微量营养元素。青岛地区棕壤土中水溶性硼的含量为0.28±0.03ppm,土壤有效钼的含量为0.11±0.02ppm,均低于临界值(硼为0.5ppm,钼为0.2ppm)。而我市大白菜种株一般植于棕壤土中,植株在生长发育过程中对硼、钼的需要不能满足。为探讨采种
Boron and molybdenum are indispensable micronutrients for the normal growth and development of plants. The content of water-soluble boron in brown soil of Qingdao is 0.28 ± 0.03ppm and the content of soil available molybdenum is 0.11 ± 0.02ppm, both of which are lower than the critical value (0.5ppm of boron and 0.2ppm of molybdenum). The cabbage plants in our city are generally planted in brown soil, the growth and development of plants in the boron, molybdenum needs can not be met. To explore the seed collection
