One, choose to build a plug bed should be selected lee, cool, and water at the construction of the plug. Overlying black shading net (60% to 70% shading rate), both sides of the shading net need to hang to the ground, so that the entire shed in a cool environment. There is no small arch on the seedbed, and the center of the arch is 40 centimeters high. Cover with a plastic film and cover with a black shading net (60% to 70% shading rate). Second, the laying of the substrate in early May, the rot leaves and perlite (1:1) mixed evenly spread in the seedbed, the thickness of not less than 30 cm. Level it and spray 0.5% carbendazim solution to sterilize. Thirdly, cuttings and cuttings can be harvested when they are in a semi-mature state. Using this method, it is not necessary to wait for the arrival of the rainy season, and it can be inserted from late May until late August. At the time of cutting, the lower blades of the cuttings were removed and soaked in a matrix with 2500 ppm to 5000 ppm (0.25% to 0.5%) B9 aqueous solution for 5 to 10 seconds. Plug a piece of water, and then cover it. The whole bed is fully closed immediately after it is plugged in, fully shaded. Fourth, after the management of cuttings due to rising temperatures, bed soil moisture will gradually reduce. In general, it is necessary to supplement the pouring of water once from the end of June to the beginning of July. When watering, it can be sprayed with 0.5% carbendazim solution and remain sealed afterwards. The buds were removed in August. If the bed soil became dry, then make up the water. Generally, the roots of August are initially grown. In the middle of September, the top shading nets can be lifted (on the greenhouses). By the end of September and early October, small arches can be opened for fertilization (inorganic fertilizer 0.1% to 0.5%) and watering ( When watering, add 0.2% of ferrous sulfate or manure water). In late October, it is covered with a small arch plastic film and shading net, and an arched pole is encrypted to prevent wind and snow. After winter, add a new layer of plastic film on the small shed to facilitate safe wintering. In April of the following year, the cover was completely removed and the fertilizer and water management were strengthened. Practice has shown that this method is simple, easy to use, saves material, is easy to manage, has a high survival rate (more than 95%), fast growth, and is suitable for mass production.
