Old mulberry cultivation techniques
Old sage, a perennial herb of the Umbelliferae family. Plant height 60-70cm, cold, moisture, avoid drought, its roots in the temperature of -40 °C safe winter. Simple production and management, less pests and diseases, rapid growth, high yield, long harvest period, leaf fat, delicious, high nutrition, and meet people's consumption concepts, from consumer-type to nutritional and health-oriented requirements. First, nursery preparation 1. Selection of nursery: flat, well-drained, leeward sunny plots. 2. Seedbed production: 7-10 days before general broadcast. Specifications 2.015m. The ratio of seedbeds to Daejeon is 1:30-50, and wooden boxes can be used for sowing. 3. Seed treatment and seed treatment: Nursery seedlings need to be planted at 10g/m2, wooden boxes are sown at 15g/m2 with 5% carbendazim 250 times for seed disinfection, and then soaked in water at 25°C for 12-16 hours. Controlled dry at -15-20 °C temperature for 10-20 days of freezing (buried and snow). Remove 2 times the mixed sand and germinate at a temperature of 20-25 °C, or direct sowing. Second, nursery 1. Nursery time: generally in April 10-20, 40-50 days before transplanting nursery. 2. Seeding method: firstly irrigate the water, fill the seedbed with fine soil after seepage, then spread the prepared seeds evenly, and then cover the 0.5-1cm with fine soil. The bed surface is covered with a layer of plastic film, ie, it is kept warm and kept warm until it emerges. Three, seedbed management 1. Temperature management: pre-emergence temperature at 25-35 °C, emergence to seedling height 4-6cm when the temperature should be controlled at 20-25 °C 10 days before transplanting, when the seedling height is about 10cm, the temperature is controlled at 15 -20 °C, hardening seedlings to prevent growth. 2. Transplanting time: May 10-20. 3. Soil preparation and fertilization: Combine the site preparation with 5000kg/667m2 farmyard fertilizer. 4. Transplanting density: 65cm ridges were transplanted with double lines of abalone seedlings, with a spacing of 20cm and spacing of 10-15cm. Fourth, field management 1. Check field fill seedlings: To preserve the seedlings. 2. Cultivated weeding: After weeding, we must promptly weed the soil and do not injure the seedlings. 5. Harvested old sagewood is a perennial herbaceous plant. The roots in the year are weak and underdeveloped, and the plant growth is not flourishing, the yield is low, and no harvesting is carried out, and rooting is performed. After the spring of the second year, the frogs are harvested and marketed, harvested once every 15-20 days, and harvested 3-4 times a year.
