六、栽培类型和栽植时间 1.露地栽植自然开花类型;8月中旬至9月中旬定植,翌年5月末至6月份开花。注意越冬管理,保墒保苗。此类型花期十分集中,产量很高,但经济效益不高。 2.冬暖式大棚或温室促成栽培类型:9月上旬定植,9月中旬即加盖塑膜开始增温加光,防止莲座丛生。此期栽培宜选用小花品种。如管理得当,翌年2月下旬至3月上旬即开花。只是技术管理条件和水平要求都较高。 3.冬季温棚越冬类型:9月上、中旬定植,冬季温棚保温,使苗安全越冬。翌年2月摘心(摘去越冬的莲座枝芽),促生新枝,加强肥水管理,4月上中
Sixth, the type of cultivation and planting time 1. Open-field planting natural flowering type; mid-August to mid-September planting, the end of May the following year to June flowering. Pay attention to the winter management, Paul seedlings. This type of flowering is very concentrated, high yield, but economic efficiency is not high. 2. Winter-type greenhouses or greenhouse cultivation type: early September colonization, mid-September that is covered with plastic film began to increase temperature and light, to prevent rosettes. This period should choose small flowers cultivated varieties. If managed properly, flowering occurs from late February to early March in the following year. Only the technical management conditions and level requirements are higher. 3. Wintering winter greenhouse type: September, mid-term planting, warm winter shed insulation, so that the seedlings overwinter. The following year in February topping (pick the winter lotus branch buds), promote new branches, to strengthen fertilizer and water management, in April on the
