Soybean breeding method

Soybeans are self-pollination crops, which often result in deterioration of the species because of mechanical intermixing, poor climatic conditions and cultivation conditions, and natural hybridization. Therefore, self-seeding seeds cannot be used for a long time. Seeds should be changed every three years. Therefore, we must persist in purifying rejuvenation and do a good job of breeding and breeding varieties in order to maintain the quality of good varieties. Method for purification and rejuvenation of soybean varieties: Selection of strains: The common method for the purification and rejuvenation of soybeans consists of the selection of individual plants, the identification of strains, and the combined high-reproduction of three steps. Separate plant nursery, plant nursery, and mixed plant nursery. Single plant selection nursery: Select the typical excellent single plant for the test, single plant threshing. Eliminate single plants that are inconsistent with the characteristics of grain color, grain shape, and umbilical color of the original variety. Line identification nursery: 1 line per plant (strain). Elimination of strains that are inconsistent with the original variety. Planting design can be used every 10 to 20 lines of 1 control line (original species) way. Selected strains for breeding in the next year. Hybrid Propagation Nursery: The above-mentioned identification of the strains and the mixed harvested seeds are planted at equal distances and then planted at high magnification. The seeds produced by the above 3 nurseries are referred to as super purified rejuvenation stocks. Mixed selection: When the soybean is mature, select a certain number of robust and excellent plants with the typical traits of the variety, and then conduct indoor rigorous selection, mixing and threshing, keep alone, and use it as breeding seed for the next year. The breeding field adopts advanced cultivation and management measures and strictly eliminates impurities. One strain: select the excellent single plant with the typical traits of the original cultivar, and make fine breeding and propagation of its offspring. This method expands the breeding of single-line harvested seeds, which is slightly longer than the strain selection method. Establishment of seed fields: The super seed stocks of soybeans obtained through purification and rejuvenation. Since there are few seeds, it is necessary to establish seed farms and multiply breeding production seeds. The size of the seed field is determined by the number of seeds sown and the yield per acre. Generally, the area of ​​the seed field can be 4% to 5% of the area of ​​the production field or the seed field at the next higher level. For the selection of plots in the seed field, land plots with flat terrain, well-drained water, uniform soil, and no heavy land or land should be used. Fertilizers were added to the farmyard and fertilizers were applied according to the ratio of nitrogen and phosphorus. Strengthen field management, and time seedlings, timely cultivating, weeding, soil cultivation, so that the soil is loose and weed free. During flowering and graining, top dressing is applied 1 or 2 times, and water is sprayed timely during drought to prevent and control pests and diseases. During the entire period of childbearing, according to the morphological traits, the seedling, flowering and maturity stages are strictly eliminated. After maturity, timely harvesting, strict grasp of harvest, threshing, etc. can easily lead to several aspects of mechanical mixing.

Our Low Pesticide Goji Berry is produced in accordance with the EU standards 0231010 : Tomatoes(goji berry is classified to tomatoes).

For the low pesticide goji berry, we control it in the planting process. A month or so before picking, it is forbidden for farmers to spray pesticides on the goji trees. In addition, we strictly prohibit farmers to use prohibited pesticides.

Of course, the types and quantities of pesticides need to be tested to confirm. We could offer organic certificate and test report, there are more than 200 items scanned by EUROFINS, Complies with EU standard.

Usually, the low pesticide goji berry`s price lower than the price of Organic Goji Berry, and the low pesticide residues are basically no harm to the human body, so the low pesticide goji`s sales is the largest.
