Rhubarb is a perennial deep-rooted plant that is suitable for sunny environments. It is better to use deep, neutral and slightly alkaline sandy loam and calcareous loam. The climate in the mountain area is cool, and areas with low groundwater levels are suitable for cultivation. Acidic soil, lime 1500-3000 kg per hectare, deep plowing more than 30 cm, full base fertilizer, 45 to 60 tons per hectare. After thawing in arid regions, soak the soil and sow the seeds. Sowing: Spring and autumn sowing can be used. The spring sowing method is: selecting the mature and full-grown seeds of the three-year-old robust plants, sowing on the eve of the spring rain. In the whole land, in the middle of April in the middle of April, the planting distance is 60-75 centimeters, spacing is 45-60 centimeters, and sowing is 5 to 10 grains per hole. It can be mixed with yellow rhizome, covering about 2 centimeters, and the seeding rate per hectare is 22 .5 to 30 kg. In the southern area, autumn sowing is adopted. The spacing of plants is 45 centimeters, and the spacing is 60 centimeters. The sowing or seedling sowing can be done between the edges of the crops such as Miki and Angelica. Timely watering, fertilizing and weeding to facilitate emergence. Seed treatment before sowing, immersed in 18 ~ 20 °C warm water immersed for 6 to 8 hours, soaked with a damp cloth to cover the germination, to be flipped 1 to 2 times a day, there are 1% to 2% of the seed can be sown when germination. Seedlings: In the spring, the rehearsal or habitat of the sun is chosen for deep plowing and flattening. The 120 cm wide seedbeds are to be made with the terrain. In the north, sowing in March, drilling, spacing 9 to 10 centimeters, covering soil 3 to 4 centimeters, emergence of seedlings in 10 days. Pay attention to moderate watering after sowing, seedling height 6 ~ 10 cm, according to live seedlings. Sorghum is used in the south and it can be broadcast on the spot. The ditch is 25 cm wide and horizontally grooved, sowing 3 cm in depth and 3 cm deep in the ditch. After applying human urine, the seeds are evenly scattered into the ditch. Every 3 to 5 centimeters, one seed is suitable, covered with fine soil or a layer of smoky soil, no seeds can be found, and covered with grass. After the emergence of the crop, cover the grass on cloudy days or evenings. After the seedlings are out, they insist on seeing the grass. Application of human urine and feces water 2-3 times to speed up seedling growth. For the first time weeding, the transplanted seedlings were transplanted and the depth of each seedling hole was required to be 30 cm, 1.5 to 2 kg of soil-fertilizer was applied, and the cover soil was about 6 cm above the bud head and 6 to 10 cm below the ground. It is good for topdressing and earth-cultivation. Field Management: Rhubarb has a long growing period and can be harvested in three years. Therefore, it is particularly important to loosen the soil, rake the grass, apply fertilizer, and prevent pests and diseases at appropriate times. Generally, in the first and second year, three times loose soil and top dressing twice. The first time in early June, chaffy cake or chemical fertilizer (150-225 kg/ha of superphosphate, 75- 112.5 kg/ha of potassium chloride, 112.5-150 kg/ha of ammonium sulfate) was chased. The second application of phosphorus and potash in late August is 150 kg/ha per hectare. The second year is top dressing 2 or 3 times. In addition, attention must be paid to the prevention and control of diseases and pests (such as root rot). Harvesting and processing: Rhubarb can be harvested 2-3 years after transplanting. During the September-October period when the stems and leaves on the ground are withered, roots and roots are sturdied, net stems and soil are removed, and the rough skin is scraped off with a bowl. Top buds and fine roots, large ropes are available for stringing, medium and small shapes can be sliced, dried or dried.
