How is the ginseng planted? Today, the focus of Huinong.com's Xiaobian is about the characteristics of low-altitude, high-altitude, mid-altitude varieties and cultivation techniques of Taizishen. Farmers in need can refer to them. 1 ginseng variety characteristics 1.1 Variety type Based on the ecological differences of variety resources, the ginseng ginseng varieties can be divided into three types: the large-leaved genus Pseudostellariae and the wild-type genus. 1.2 Ecological adaptability and fertility characteristics Eucalyptus grandis is suitable for cultivation in low-altitude hilly ecological areas. Wild-type Pseudostellariae is suitable for cultivation in high-altitude mountainous ecological regions, while lobular-type P. sinensis is suitable for cultivation in mid-altitude mountainous and hilly ecological regions. P. ginseng is mainly rooted and has the characteristics of germination and growth under low temperature conditions. In the production area, P. chinensis should be planted in the end of October. When the temperature drops below 15 °C and the soil temperature reaches 10 °C, the ginseng It will begin to sprout slowly and roots. After the winter, the seedlings will be unearthed in the second year. The seeds of Radix Pseudostellariae will rupture and excrete seeds, and artificial seed collection has certain difficulties. The natural germination rate of seeds of P. ginseng seeds is not high. If artificial seeds are used for breeding, low temperature treatment is needed. Therefore, ginseng production The area is generally propagated using species of ginseng. 1.3 Plant characteristics The large-leaf type of Radix Pseudostellaria has broad leaves, more leaves and branches, thick stems, clear main roots, large and small roots, and a spindle shape. The wild type of Radix Pseudostellariae is long and thick, with few branches, the main root is not clear, the roots are small and many, and the roots are carrot-like. The leaves of P. sinensis are long and small, with many branches and leaves, thin stems, clear main roots, small and many roots, and round roots. Taken together, the lobular variety is an excellent variety of P. chinensis, and this variety is also a high-quality and high-yield type of P. heterophylla. Wild-type varieties have high disease resistance. Large-leaf varieties have low yield and low disease resistance, but they have the advantages of large size and beautiful appearance. 2 Cultivation techniques of Radix Pseudostellariae 2.1 Large leaf type ginseng variety The method of using arch cultivation is higher in yield than the method of planting in the sorghum. With large ginseng and medium ginseng as propagation materials, the emergence rate is higher than that of small ginseng. The row spacing should be set to 16.7 cm × 5 cm, and the planting density is about 1.2 million plants/hm2, using low-level top dressing. The bud processing and the shading treatment can further increase the yield. 2.2 Small leaf type ginseng variety The yield of using the method of arch cultivation is higher than that of using the method of planting flat. Compared with small ginseng, large ginseng and medium ginseng were used as propagation materials, and the emergence rate was higher. The row spacing should be set at 12.5 cm × 5 cm, and the planting density was maintained at 1.6 million plants/hm2. Topdressing is based on low-level topdressing. The bud treatment does not increase the yield, and shading can increase the yield. 2.3 Wild type ginseng varieties The method of using arch cultivation is higher in yield. Large ginseng and medium ginseng are used as breeding materials, and their emergence rate is higher than that of small ginseng. The row spacing should be set at 12.5 cm × 5 cm, and the planting density is between 1.2 million and 1.6 million plants/hm2. The bud treatment can further increase the yield, but the shading treatment does not significantly increase the yield. First, different land preparation methods have different effects on the yield of Radix Pseudostellariae. The yield of the large-leaf type Pseudostellariae and the lobular type P. sylvestris using the arch cultivation method is higher than that of the flat planting. The large-leaf type of Radix Pseudostellariae and the lobular type of Radix Pseudostellariae are all artificially domesticated varieties. Their disease resistance is not high, and they are more susceptible to mosaic disease. To increase the yield of these two, the number of diseased plants needs to be reduced accordingly. Wild type Pseudostellariae has strong disease resistance. Although the method of using arch cultivars is lower than that of sorghum planting, it still has increased yield. This is because the soil layer of arch cultivars is thicker and can be used for ginseng rooting. Get good growth, which in turn promotes the growth of P. heterophylla. Second, most of the ginseng is to use the underground roots as a breeding material. When selecting the ginseng, the ginseng is sold as a large ginseng as a ginseng, but the germination rate of the large ginseng and the medium ginseng is higher than that of the small ginseng, so consider At this point, it is recommended to use 7.5-1.25 g/root of Radix Pseudostellariae, which is a medium-sized ginseng, as a breeding material to obtain high-yield, high-efficiency and high-quality ginseng. Third, the plant spacing will also have some impact on the production of P. heterophylla. The cultivation of Euonymus japonicus should increase the row spacing and reduce the plant spacing, that is, the row spacing is 16.7 cm and the plant spacing is 5 cm. For wild-type P. chinensis, the row spacing and plant spacing should be appropriately reduced, that is, the row spacing is set at 12.5 to 16.7 cm, and the plant spacing is set at 5 cm. The cultivation of the lobular type of Radix Pseudostellariae should be appropriately reduced at the same time as the row spacing and plant spacing. Therefore, the row spacing is 12.5 cm and the plant spacing is 5 cm. From this point of view, for these three varieties, the row spacing of the large-leaved genus Pseudostellariae is appropriately increased, the row spacing of the lobular genus Pseudostellariae is appropriately reduced, and the wild-type ginseng is between the two, which can obtain a better yield-increasing effect. . Fourth, the extraction of buds and shading treatment will have an impact on the yield of Taizishen. As a plant with roots and stems, the underground part of Radix Pseudostellariae is the main source. The flowering of the aboveground part will directly affect the transmission of nutrients to the ground. Therefore, the extraction of buds will increase the yield of Taizishen, under the same conditions, different management. The effect of the mode on the yield of Radix Pseudostellariae is shown in Table 1. In addition, in Fujian, the summer temperature is higher, and the growth temperature requirement of P. chinensis is lower. Therefore, the shading treatment delays the seedling time and prolongs the growth period, which is beneficial to increase the yield of Radix Pseudostellariae. Table 1 Effect of picking buds on the yield of Taizishen 3 Conclusion In the application of high-yield supporting cultivation techniques for P. chinensis, it is recommended to strengthen from seven aspects: soil preparation, seed selection, rational close planting, film mulching, fertilizer control, bud removal and shading. The use of arch cultivation is beneficial to control the disease problem of Radix Pseudostellariae and increase the yield of Radix Pseudostellariae. Using medium-sized ginseng as the main material for breeding, set the row spacing of plants to 12.5 cm × 5 cm and 16.7 cm × 5 cm, supplemented by reasonable dense planting, and control the planting density at 1.2 million to 1.6 million plants/hm2. about. In addition, the cultivation method using the mulch film can prematurely germination of the ginseng ginseng, retreat and pour the seedlings, and effectively prolong the growth period of the ginseng ginseng to greatly increase the yield of the ginseng. Because Radix Pseudostellariae has strong non-fertilization, it is mainly based on base fertilizer and organic fertilizer. In the process of its growth, a small amount of NK compound fertilizer is added, which helps to promote the rapid growth of plants. And then increase production. For the multi-flowered variety of Eucalyptus grandis, the appropriate bud extraction is beneficial to increase yield. Shading treatment has a positive effect on the safety of the ginseng ginseng, the summer, the post-pushing rice seedling, the prolonging the growth period and increasing the yield. It is recommended to use soybean as a product of shading. In the later stage of growth of Radix Pseudostellariae, interplanting between rows and rows can promote the yield of Radix Pseudostellariae. Finally, Hui Nongwang Xiaobian reminded everyone that as a kind of species with great nutritional value and economic value, only by understanding the growth characteristics and mastering the good cultivation techniques can the ginseng get healthy growth and realize its Maximize economic efficiency.
