用种子繁殖和扦插繁殖。栽培技术
Propagation by seed and propagation by cutting. Cultivation techniques.

1、种子繁殖：春播3月下旬至4月上旬，秋播9月上旬，因栽培周期长，故一般少用此法。2、扦插繁殖：每年4-5月进行，选取粗壮、无病虫害的当年生植株，剪取长约4-5cm的插条，每插条带1-2片叶，按行株距6cm×5cm扦插，入土3/4为宜，然后压紧，浇水，保持土壤湿润，般每1h㎡用种苗1125kg左右。病虫防治

1. Seed propagation: Sow seeds in late March to early April in spring, and in early September in autumn. Due to the long cultivation period, this method is generally less commonly used.2. Cutting propagation: Conducted annually in April to May, select robust, disease-free young plants of the current year, cut 4-5cm long cuttings, each with 1-2 leaves, and plant them with a spacing of 6cm x 5cm. It is advisable to plant them 3/4 into the soil, then press firmly, water, keep the soil moist, and use about 1125kg of seedlings per hectare. Disease and pest control.

有细菌性软腐病和排草斑枯病，为害叶片、茎杆等。防治方法：①田间病叶率达到1%-2%或烂顶率达0.1%，可用农用链霉素2×10-4+75%百菌清可湿性粉剂500倍液防治，效果可达80%-90%以上。残效期1个月左右。②冬季清园处理和烧毁残体，减少越冬病源。③种植时进行种苗消毒。
There are bacterial soft rot and leaf spot diseases, which damage leaves, stems, and so on. Prevention and control methods: ① When the disease leaf rate reaches 1%-2% or the rotten top rate reaches 0.1% in the field, it can be treated with 2×10-4 agricultural streptomycin + 75% copper oxychloride wettable powder at a dilution of 500 times, with an effectiveness of over 80%-90%. The residual efficacy period is about one month. ② Clearing and burning residual plants in the garden in winter to reduce overwintering sources of the disease. ③ Disinfecting seedlings during planting.
