结球甘兰又称球菜、包菜、洋白菜,适应性广,种植面积大,栽培简便,产量高,营养丰富,并含有大量的碳水化合物、钙、磷、铁及维生素丙,除熟食外,还可醃渍晒干,外叶是极好的饲料。对外界适宜的温度为摄氏18～21度,如过高,结球就不好,过低生长缓慢。抗寒力较强,能耐摄氏零下6～8度,种子发芽适温为13～18度。由于叶面积大,水分消耗大,加上根层分播浅,因此,需要保持土壤湿润。在栽培上应掌握以下几个环节:(一)掌握规律选用良种
Cabbage also known as cabbage, cabbage, cabbage, wide adaptability, planting area, cultivation is simple, high yield, nutrient-rich, and contains a lot of carbohydrates, calcium, phosphorus, iron and vitamin C, except cooked , But also pickled dried, the outer leaves are excellent feed. Suitable for the outside world temperature is 18 ~ 21 degrees Celsius, such as too high, the ball is not good, too slow growth slow. Strong cold hardiness, able to Celsius minus 6 to 8 degrees, seed germination suitable temperature 13 ~ 18 degrees. Due to the large leaf area, water consumption, coupled with shallow root sub-broadcast, therefore, need to keep the soil moist. In cultivation should grasp the following aspects: (a) master the law selection of elite
