1对环境条件的要求1.1温度羽衣甘蓝耐寒性很强,喜好冷凉气温,同时也耐高温,幼苗能短时间耐-12℃的低温。露地栽培的成长株能短时间经受几十次霜冻,但不耐长期连续严寒,采种株需要通过春化才能抽薹开花,一般要求在2~10℃温度下30天以上。其种子发芽适温为18~25℃,生长适宜温度为20~25℃,虽在夏季35℃高温中也能生长,但高温季节生长的叶片风味差、纤维多、叶质硬。1.2光照羽衣甘蓝属长日照作物,在充足的光照条件下叶片生长快、品质好,同时较耐阴。采种的植株首先
1 on the environmental conditions 1.1 temperature kale strong cold, like cold temperature, but also high temperature, seedlings can withstand short-term low -12 ℃ temperature. Growing plants in open field can withstand dozens of frosts for a short time, but are not tolerant to long-term continuous cold. Seed plants need bolting and flowering through vernalization. Generally, temperatures of 2 to 10 ° C are required for more than 30 days. The optimum temperature for seed germination was 18 ~ 25 ℃, and the suitable temperature for growth was 20 ~ 25 ℃. Although the seeds grew well at 35 ℃ in summer, the leaves with high temperature had poor flavor, more fiber and hard leaf. 1.2 light Kale is a long sunshine crops, leaves in sufficient light conditions, fast growth, good quality, while more resistant to overcast. Seed plants first
