Sunwu County of Heihe City is a famous hometown of Chinese fruit seabuckthorn. Nowadays, hemp planting has become another major industry in the adjustment of local agricultural structure. The planting area has exceeded 80,000 mu. In April 2016, Sunwu County was named China by China Hemp Textile Association. The hometown of Hanma. Hanma experts of China Hemp Association have determined that the quality of Hema in Sunwu County is the best in China, and the indexes such as spinnability and flexibility are the best.

Hemp, also known as line hemp, cold hemp, hemp, etc., the name is said to be more than ten kinds. History book, hemp originated in China, the clothing made of it has the functions of moisture absorption, breathability, comfort, heat dissipation, mildew proof, bacteriostatic, radiation resistance, UV protection, sound absorption, etc., both military and civilian. . In terms of the effect of making antibacterial socks, it has been widely praised. Hemp is the earliest natural fiber used by humans for fabrics. It has the reputation of “the source of national textiles and the ancestral clothing of Wannian”. Its planting history has been at least 8,000 years.

Sun Wu Hanma quality technical requirements I. Variety Long-hemp series, Qingma series and other national and local registered varieties. Second, the site conditions are located at 126°40? to 128° east longitude, 48°59? to 49°42? north latitude, the annual average temperature is -0.6°C, the average sunshine is 2551.5 hours, the average snowfall is 215 days, and the frost-free period is 90-120. Days, high latitudes and alpine regions. The soil is meadow soil, peat soil, and dark brown soil. The soil is rich in organic matter, including silicon, manganese, magnesium, calcium, iron, selenium, tellurium, strontium, zinc and other elements and minerals, with a pH of 6.3 to 6.5. 3. Field management 1. Seed treatment: Seed dressing: 10% metalaxyl + 48% mancozeb + 75% carbofuran (or 15% carbendazim) with 0.1% seed before sowing 75% Carbide + 10% Familia double seed dressing to prevent pests and diseases. 2. Site selection and selection: Site selection: Pingchuan, Pinggang, and well-drained two-story land with deep soil layers, loose structure, fertile structure, and strong water and fertilizer retention capacity should be selected. The pH of the soil is preferably neutral and slightly alkaline. Election: A reasonable rotation of 4 to 5 years should be carried out, and the cultivation of hemp should be avoided. On the basis of reasonable rotation, corn, soybean and wheat bran are used. 3. Tillage and land preparation: Tillage and land preparation method: The former plots without deep foundation and deep pine foundation should be turned over and smashed. For the former plots with deep-turning and deep-slung foundations, the autumn rafts should be carried out to reach the state to be broadcasted. Site preparation quality: After ploughing and land preparation, it should reach the upper and lower level, the land is flat, the topsoil has no large clods, and the plough layer has no dark shovel. The clods of 3cm to 4cm diameter per square meter should not exceed 5 pieces. 4. Fertilization: According to the principle of combining organic and inorganic, nitrogen, phosphorus, potassium and trace elements, balanced fertilization is implemented. Apply 1500 kg of organic fertilizer per 667 m2 (mu). The organic fertilizer is applied and combined with the grounding into the soil of 10cm to 15cm. Inorganic fertilizer should be applied as a single fertilizer. When the soil is frozen to a depth of 10cm, the plot will be flattened and operated with twenty-four rows of planters. The depth of fertilization is 8 to 10 cm. There should be no leakage or heavy application during operation. Generally, compound fertilizer (N: P2O5: K2O = 16:16:16) is applied for 13 to 15 kg per 667 m2 (mu). 5. Sowing: Sowing date: From late April to mid-May, the soil temperature of the sowing layer is stable through 7 °C to 8 °C, that is, it is suitable for sowing. When the cultivation area is large, it can be planted in stages, with an interval of 5 days per period to reduce the harvest pressure. Seeding method: repeated sowing or seeding row spacing of 7.5 cm was carried out with a 48-row seeding machine, and the sowing depth was 3 to 4 cm. Deep soiling can be carried out when the soil moisture content is low, but the sowing depth should not exceed 5 cm, and it should be suppressed in time. Plots with sufficient soil moisture or soil viscosity can be suppressed within 1d to 2d after sowing. 6. Prevention and control of pests and weeds: chemical herbicide: weeding and weeding with Jindur before sowing; seedlings can be used before the seedling height of 10cm in early June, and 32.5 to 5 leaves in grasses % of the flax emulsifiable concentrate 1.2kg to 1.5kg with water from 400kg to 500kg evenly sprayed, to prevent grasses. Disease control: gray mold, stalk rot and other diseases, using seed weight 0.1% 10% metalaxyl + 48% mancozeb + 7% carbofuran compound (or 15% carbendazim + 75%) Carbofuran + 10% Fumei double) seed dressing. Other hemp disease prevention and control should be based on the condition and climatic conditions, in the early stage of the disease, timely spraying, inhibiting the occurrence of disease. Pest control: In addition to pesticide dressing, seedling stage pests such as Flea and Weevil can be controlled with methyl 1605 powder (or the same effect agent). The damage of armyworms and grasshoppers during the period of growth can be controlled by spraying with pyrethroid pesticides such as cypermethrin and deltamethrin. The control period is from 2 to 3 years old larvae. 7. Harvest: Harvest at the right time: Hemp should be harvested at the right time of the process. The sign of the maturity of the process: the pollen of the female plants in the Ma Tian is exhausted, the plants become pale yellow, the leaves turn yellow and have not completely fallen off; the seeds of the base of the female plants are partially mature, and the leaves at the base of the plants turn brown and begin to fall off. Harvesting method: It is harvested by special healing machine with hemp, and it is required to make the laying without disorder and the thickness is consistent. 8. Rain Dew System: After the hemp mechanical harvest (or artificial harvest), it is placed in the hemp for rain and ice. The general temperature requirements are early (8 o'clock), medium (14 o'clock), late (20 o'clock), the average temperature is greater than 18 ° C, the relative humidity is greater than 65%, and 20 to 30 days can be successfully produced. The cannabis harvest time must be harvested before the August 25th of each year. After the smashing of the dried cannabis stems, it is necessary to concentrate the manpower with the stalks and stand in the laps to prevent excessive smashing and mildew. 4. The special packing machine for transportation and storage will be made into a hemp shape with a square shape of 75 kg. The height of the storage warehouse is not less than 5M, and the surface of the ground is required to have a moisture-proof layer of 25CM. The stacking height must not exceed 4M; Do fire and rain protection measures. V. Processing First cut the dry hemp stem into the hemp section of 75 to 85CM, use B-870 stripping equipment, and process according to the normal operating procedures; the processing time is selected from October of each year to April of the second year. 6. Quality characteristics 1. Sensory index: Table 1 Sensory index Project indicator color yellow, silver-gray length (M) 0.70-0.85 2. Physical and chemical indicators: Table 2 Physical and chemical indicators Project index splitting degree (Nm) 60-69 Hemp bundle fracture Specific strength / cN / dtex 1.4-1.7 Hemp bundle strength / N u003e 500 3. Safety and other quality technical requirements: Product safety and other quality requirements must comply with relevant national regulations.
