This method is more traditional, mainly for the purpose of producing terminal buds, because up to now, artificial open field propagation is still in the primary stage, farmers mainly collect wild stems on the mountains, most of which are prickly and not full, and the buds of lateral buds are dry, so they can only produce terminal buds.

(1) Stem preparation: collect stems with a diameter greater than 1.5 cm, cut them into 30 cm lengths with a chainsaw, and then bind 50 rhizomes into bundles. It is worth noting that once the length is determined, it cannot be changed from beginning to end, because the top must be neat and consistent after being put into the waterbed. In addition, when binding, it should be tied at 2/3 from the top, which is convenient for loose operation at the top after sitting on the waterbed and avoids overcrowding.

② Preparation of facilities and materials: Waterbeds should be built in greenhouses in advance, and the grade of waterbeds can be determined according to economic conditions. If the conditions are good, water-mud beds can be built and industrial production can be carried out, but for ordinary farmers, simple and practical methods can be adopted without large investment. The size of the bed is about 1.2 meters wide. If it is too wide, you can't reach the middle when you operate it manually. If it is too narrow, the proportion of trails is large, which wastes the greenhouse area. The direction should be north-south, the bed spacing should be 30 cm, the width of the trail should be 70 cm along the back wall, and the front bottom corner should be set aside for 0.5 m. Then, a drainage ditch should be dug along the front bottom corner to facilitate the discharge of wastewater when changing water. When making the bed, make a bed about 15~20 cm high. In short, the bottom of the bed should be higher than the drainage ditch, and it should be flat and slightly inclined to the side of the drainage ditch, so as to discharge wastewater into the ditch when changing water. After the mud bed is completed, make a wooden frame with a height of 15 ~ 20cm according to the specifications of the bed and put it on the bed surface. The end of the wooden frame near the drain should be provided with a drain. After the bed is made, spread the agricultural film with a thickness of more than 0.05mm and put the film around the wooden cabinet. It is worth noting that the agricultural film with a thickness less than 0.05mm is easy to be punctured, so it cannot be used. For safety reasons, it is best to put it on the bed. In addition, there are small-diameter wells and submersible pumps in the greenhouse. After the bed is made, 0.04 mm thick bamboo strips and agricultural film should be prepared for production.

(3) Operation method: After the preparation work is completed, you can sit on the waterbed one by one with the stems of the bundled buds facing upward, and loosen the upper part by hand after sitting. According to this density, the pure area per square meter can reach about 800 plants. After installing the stem, water it immediately, and the water depth is 5~6.7 cm. Many farmers add a small amount of urea to the nutrient solution after irrigation, but experience has proved that this is unnecessary, because the nutrients stored in the stem are enough for the growth of buds, and the stem has no root system, so it is difficult for inorganic salts in water to be transmitted and transformed through the stem. Moreover, if the thorn buds are managed by stagnant water, the stems will soon become moldy, which will eventually lead to soft rot and gray mold. So this is also the main reason why farmers often die in their own farming. After irrigation, the stems should be treated with carbendazim and gibberellin. The main function of carbendazim is to sterilize and control gray mold and soft rot. The main function of gibberellin is to break the dormancy of buds, promote buds to germinate early, concentrate germination time and improve the uniformity of buds. The experiment showed that the germination time of gibberellin treated stems was at least 1 week earlier, and the germination speed was faster. During the treatment, 800~ 1000 times of carbendazim and 50 ml/l gibberellin are mixed together, and then all of them are sprayed, and the dosage of liquid medicine is 300 ml per square meter. The last process is to make a small arch shed with bamboo bows and buttons. The arch shed should be as high as possible to leave some room for the growth of buds. The small arch shed can play a buffering role, and the buds in the shed will not suffer from freezing injury. Second, it can ensure the humidity of the space in the shed and promote its germination as soon as possible. After budding, it can be used as a supplement to the moisture of the bud, reduce the transpiration of the bud and keep the bud growing vigorously. This method uses not only the terminal bud, but also each lateral bud. Because the aquatic method only uses terminal buds, it not only wastes resources extremely, but also increases the production cost. The wood cutting method solves this contradiction. As far as the stem price is concerned, the cost of wood cutting method is 60%~70% lower than that of hydroponics method. Most of the lateral buds of wild stems are not full, so the lateral buds are small and the yield per unit area is not high. The best way is to cultivate varieties with fewer thorns and bigger buds, and then cultivate and propagate stems in the open field.

① Stem modulation: This method uses lateral buds, so it is necessary to select a stout stem for modulation, and the diameter of the stem should be more than 2 cm. Stem modulation is mainly to cut the stem into sections of about 10 cm, the length of thorn buds is about 10 cm, and each section has a lateral bud, so each cut section has a lateral bud. Cutting tools include chainsaws, fruit tree scissors, kitchen knives and other instruments. Practice has proved that the cutting speed is the fastest only with fruit tree scissors. In order to save labor, one side of the scissors can be fixed to make a simple hay cutter. When cutting, it is cut from the bud 1 cm along the back at a 45-degree angle, so that the two ends of the modulated wood section are oblique stubbles. The advantages are that the head is easy to insert into the substrate when cutting, and no water drops are left on the uphill after watering, thus reducing the degree of rot and mildew; Second, after high-density cutting, gaps are formed between the upper slopes, so that the buds will not be so crowded after they are sent out. As for whether the length of wood segment is 10 cm, some people have done experiments, and the result is that the bud weight has little to do with the length of wood segment, but has a direct relationship with the thickness, so it is necessary to cultivate thick stems as much as possible. After cutting, the water in the body will soon be lost from the cut surfaces at both ends, so cut while cutting.

(2) Preparation of facilities and materials: First of all, the logging method needs to build a hotbed in the greenhouse, with a bed width of 1.2m and a trail width of 0.3m, which is vertical from north to south, and there is no need to set a drainage ditch in the front foot. When making the bed, first dig down to the depth of 10 cm according to the size, and then use a wooden frame with the width of 12 cm to spread a layer of agricultural film on the bottom of the bed, and make holes sparsely, so as to leak downward after watering. Finally, the bed is filled with a matrix with the thickness of 10 cm.

Three materials are used in the matrix. The first kind is sawdust, which has high moisture content and certain heat preservation effect. Today, sawdust of broad-leaved trees is used. Therefore, whether the sawdust of coniferous trees can be used is inconclusive without practice. Only with the prohibition of deforestation, the price of sawdust has risen, and the used sawdust can only rot naturally and be purchased next year. The second is perlite powder, which is characterized by light weight and easy cutting. After high temperature treatment, perlite does not contain any bacteria, which is beneficial to prevent diseases. Perlite powder can be dried, bagged and stored for the next year, so the one-time investment of perlite powder is larger than sawdust, but the cost is still lower than sawdust. Practice shows that perlite powder with smaller particles should be selected as far as possible to make the bed surface difficult to dry. The third is the use of asbestos, which can not only be reused, but also has the best water retention performance. According to the data, asbestos is widely used in Japan now, but it needs practice to know whether it is easy to cut. Other materials are prepared in the same way as aquatic products, including wells, pumps, bamboo bows and agricultural films. Is an essential thing.

③ Operation method: When cutting, the density is 800~ 1000 per square meter, the cutting concentration is 2/3 of the wood segment, the direction is inclined to the north and the buds are directed to the south. After cutting, water is poured once, and after the surface of the wood section is dried, drug treatment is carried out. The method is the same as the aquatic method, spraying carbendazim and Gibberella, and the logistics department immediately inserts the bow buckle membrane.
