Cultivation methods of Agastache rugosa: 1. Cultivation techniques
Propagate with seeds. When most of the seeds turn brown, harvest them, put them in a cool place, ripen them for several days, dry them in the sun and thresh them. When the temperature is higher in South China, it can be sown in autumn. From September to October, the holes should be opened according to the row spacing of 30cm, the depth of 2-4cm, and the bottom should be flat. After applying human and livestock manure water, 7.5kg seeds should be used every 1hm2. Mixed with plant ash and evenly sown in the hole, the yield is higher. Sowing in March to April in North China, the row spacing along the border is 25-33cm, the small shallow furrow of 1-1.3cm is opened, the seeds are evenly sown in the furrow, the soil is covered with 2-4cm, the groin is used once, the seed is 7.5-12kg per 1hm2, the yield is low. When the seedling height is 6-10cm, the seedlings are kept according to the plant spacing of 10-15cm in drill sowing, and 3-4 seedlings are kept in each hole in hole sowing.
2. Field management
Soil loosening and weeding should be carried out in time during the growing period. Nitrogen fertilizer is the main topdressing. When the height of seedling is 15cm and after harvest, nitrogen fertilizer should be applied once, and the topdressing of seedling should also be considered. Attention should be paid to irrigation and drainage to keep the field moist. Agastache rugosa is propagated by seeds. When most of the seeds turn brown, harvest them, put them in a cool place, ripen them for several days, dry them in the sun and thresh them. Before sowing, seeds were coated with new high fat film and plant ash to avoid underground diseases and insect pests, isolate virus infection, strengthen respiration and improve seed germination rate. The seeds were evenly sown in the hole, and the yield was higher. During the growth of Agastache rugosa, the soil should be loosened and weeding should be carried out in time. The top dressing is mainly nitrogen fertilizer, and the top dressing of seedlings is also needed. It is necessary to pay attention to irrigation and drainage to keep the field moist. And spray zhuanggangling at the right time to make the plant strong and prosperous. At the same time, it can improve the ability of disaster resistance, reduce the amount of pesticide and fertilizer, and reduce the residual poison.
3. Pest control
Brown spot occurred in May and June, and the diseased leaves could be removed and burned in time; The rotation was carried out, and 1:1:100 Bordeaux solution was sprayed before and at the beginning of the disease. The control of leaf spot disease can be carried out in winter by clearing the withered leaves and burning them, and spraying 50% ruidu mould 1000 times. The Fusarium wilt can be drained in time after rain to lower the temperature; In the early stage of the disease, the diseased plants were removed and the diseased acupoints were irrigated with 1000 times of 70% dikesong powder or 500 times of 40% carbendazim glue suspension. The pest is red spider mite.
