Brown Liw Cutting Branches for Rapid Seedlings

Brown Lee is a high-grade plum variety introduced into China in recent years. It has the characteristics of individual (80-200g single fruit weight), strong adaptability, delicate fruit flesh, rich flavor, and fruit storage and transportation. It is deeply favored by growers and consumers. At present, cultivating U.S. Brown Plum Series seedlings mostly uses nectarine, apricot, and Li as rootstocks for grafting, but their breeding speed is slow. Experiments show that the tender shoot cutting seedlings are the best way to speed up the breeding of American brown plum seedlings. The survival rate of cuttings is 90%, the survival rate of transplanting can reach more than 86%, and the whole process of nursery is only about 40 days, which greatly shortens the time of nursery. The main technical introductions are as follows:
First, build a seedbed in the shade to take a plastic (with bamboo, wood, straw material can be) shed, clean the shed inside the venue, and use fine river sand to make a cutting bed. The cutting bed is sterilized with 0.5% potassium permanganate solution or 50% carbendazim or 70% thiophanate or 58% mancozeb 500, and the sprayed amount is on the surface of the moist sand bed. For degree. The temperature in the booth is maintained at 20°C to 28°C and the relative humidity is not less than 70%. Since it is a tender shoot cutting with leaves, natural scattered light must be allowed to irradiate the shed in order to facilitate the photosynthesis by cuttings. Shed size depends on the number of seedlings. Generally about 250 fertile rice seedlings per square meter.
Second, the collection of cuttings from the disease-free zone harvesting fruiting period robust mother trees with young twigs (early spring cuttings can be collected last year without sprouting, the thickness of 0.7 cm is good) for cuttings, length 10 cm to 20 In centimeters, keep 2 to 3 leaves or 3 to 5 halves in the upper part. Shear cutting varieties can not be mixed, and timely labeling. The cuttings require semi-lignification without pests and diseases. The cutting strips are bundled into 50 pieces per 100 to 100 pieces, and the portion about 2 cm long at the base is immersed in an ABT rooting powder solution of 0.005% to 0.01% or 0.025% naphthylacetic acid solution for half an hour to 1 hour.
Third, timely cutting knife with a sharpened base. Before cutting, first use a wooden stick to make holes in the cutting bed, and then insert the cuttings into the holes, cutting them to a depth of 5 to 8 cm, and spacing between 6 and 8 cm. Immediately after the cuttings, water and water the shed.
Fourth, after the plug-in management attention after plug in the temperature, bed humidity and ventilation, light conditions, such as noon high temperature, to spray more cold water. In order to ensure the required temperature and humidity for cuttings, the moisture content of the cutting bed should be reduced as much as possible to prevent overgrowth. Seven days after insertion, callus formation began. After 15 days, the cuttings began to grow roots. When the number of roots reached 10 or more, and the length of roots reached 5 cm or more on average, they could be transplanted.
