At present, it has entered the season of Yangliushu cutting and seedling raising. Now Yangliushu cutting seedling raising technology is introduced to farmers' friends for reference. Nursery selection and site preparation The fertile, wet, and well-drained soils should be selected for the nursery, and the nursery should be selected in a place convenient for irrigation to ensure that it can be watered at any time. Before the cuttings, the nursery must be leveled and fine-grained so as to avoid drought at high altitudes and low water at the time of irrigation, resulting in irregular seedlings. Species selection and collection The quality of strips is an important factor affecting the survival rate. One-year-old seedlings should be used as seed strips. One-year-old shoots should have high rooting rate. The species grows robustly, without pests and diseases, and has a good degree of lignification. The species must be collected before the sprouting of the trees. They are collected about mid-March and stored in an environment below 5°C. During storage, they should be buried with wet sand, or they should be placed in wet sand to prevent water loss. Cutting shear Cut a full section of lower and middle shoots for cuttings. The length of the cuttings is 15-20 cm. There must be one bud at a distance of 1 cm from the top. After the ear cutting, 50-100 spikes are bundled according to the coarse classification. Do not turn the shoot upside down to prevent it from inverting. Cutting treatment The bundled cuttings should be immersed in water and the immersion time should be 12-24 hours. Infusing the cutting not only can make it absorb enough water, but also can remove rooting inhibitors in cuttings, which has obvious effect on improving the survival rate. It is especially important to soak in water from the field. Cutting time After the soil is thawed in spring, it can be cut. Early intervention at the right time is good for improving the survival rate. Our province is generally in mid-April. Cutting method The ridge cultivation is convenient for mechanical or animal husbandry management. The ridge width is 60-70 centimeters, double row 80 centimeters, and plant spacing 15-20 centimeters. The double rows are inserted in the wrong position. When the ground is hard, firstly perforate and then insert the cuttings. The cutting depth is generally suitable for exposing one bud on the ground. In drought and sand, it can be fully inserted into the earth, and the upper end is level with the ground. Never insert a cutting plug when cutting. Cuttings should be cut according to the thickness of the cuttings, so that the seedlings can grow neatly and avoid bullying. Immediately after cutting, water should be poured to make the cuttings tightly integrated with the soil, which will help the cuttings to absorb enough water. Post-insert management Irrigation. After the poplar and poplar cuttings germinate, the nutrients contained in the cuttings themselves and the water extracted from the soil in the lower incision maintain the life and growth. After entering the rooting stage, the young leaves grow on the top of the seedlings, and the seedlings begin to grow truly. The seedling rooting period lasts until mid-May. The temperature keeps rising during this period. The water consumption of seedlings gradually increases. At this moment, once the supply of water is insufficient, the water dynamics of the seedlings will be unbalanced, and wilting will occur until death. Therefore, the key to managing this period of time is to ensure the supply of moisture. Wiping buds. After the cuttings survived, the lateral branches grew. When the lateral branches grew to about 20 cm, a robust lateral branch culture trunk should be selected in time to remove excess sprouts. With the growth of the cutting seedlings, the lateral buds growing on the seedlings should be promptly removed. Develop straightforward trunks.  Sterile Surgical Gown Sterile Surgical Gown,Blue Disposable Overalls,Isolation Gown Suit,Disposable Isolation Gown Haloxylon Ammodendron Medical Equipment Co., Ltd. , https://www.haloxylonl.com
