Jujube rapid propagation technology

1 The built-bed splice bed was built under the full-light conditions of the exposed area, and it was made of bricks to make a 1.2-1.5m wide slotting machine, depending on the size of the long view, the water pipe with mist nozzles was erected on the plug bed. 2 Substratum is laid with 30cm thick pebbles or pebbles, and the upper layer is covered with coarse sand 20-30cm, and then sprayed with 0? 2% potassium permanganate solution. 3 Cutting preparations The first and second branches of non-woody jujube were collected in June and July. The ear cutting time is best at 8 o'clock in the morning. If it needs long-distance transportation, it will be magnified and immersed in the clear water immediately after harvesting, and then put into a shaded plastic bag. Immediately after the return, it will be cut into small pieces of 15-20 cm, and the upper leaves will be retained. , Remove the lower 3-5cm segment of young leaves, soak 50 minutes and put 500mg of carbendazim in 800-fold solution for 5 minutes, then use 300PPM of D-type rooting powder and 300PPM of C-type rooting agent to cut the base for 10 seconds. After the bell is removed, it is cut into 2*3CM rows at a distance of 2-3cm. 4 Immediately after the insertion, the full-light intermittent misting device shall be activated. Before the rooting, the spraying interval time shall be short to keep the foliage with a layer of water film. After rooting, it shall be sprayed once every day for 20-30 minutes and once for 1-2 hours at night. . The spraying time is extended 6 days before transplanting, usually 40-60 minutes. About 15 days after the insertion, a foliar dressing (0?2% urea solution) was performed, and 50% carbendazim was sprayed once a week for 1000 times. 5 The use of this technology can make the rooting rate of jujube more than 93%, 9-10 days after the insertion of callus production, 15 days to begin rooting. It is an advanced technology for implementing rapid propagation of excellent jujube varieties. China Agricultural Network Editor
