Sily pods are known as milk thistle, milk thistle, mouse le, milk lice. Amaranthidae is a plant of the plant Silybum, which is used as an achene. The following key technologies should be mastered for the planting of silymarium. First, the soil of the selected silymarin is not strict to the soil, and it can grow normally in the wasteland, wasteland, saline-alkali land and mountainous area. Because it is not easy to manage, it is difficult to harvest by hand. It is best to choose to grow on the land, on the edge of the forest, on the edge of the forest, on the edge of the ditch, on the roadside. This is not only convenient for harvesting, but also a natural choice for low-lying plots. For mechanical harvesting operations, flatter plots should be selected. Second, the site of silybium growth lush, infertile land, 667 square meters when the preparation of organic fertilizer 4000kg, 15kg of diammonium phosphate, urea 8kg scattered evenly, turning in the soil in the depth of 20-30cm. The soil is required to be finely crushed in order to facilitate the emergence of seedlings. In the ground, ditch planting, can be 60-70cm ridge distance, from 4-6 ridges, a large area planted ridge 65-70cm. Third, the cultivation methods 1. Sowing (1) seed selection, large, full, black, no pests, high seed germination rate. (2) Seed treatment Use 0.3% carbendazim or bacteriostatic seed dressing to prevent disease. Pest-enhanced plots can be used for phoxim dressing and pest control. (3) Seeds of silymarin seedlings and seedlings are not afraid of freezing and can be sowed at the top of the soil. It can be planted by planting wheat. The southern part of Heilongjiang Province is in early April and the northern part is in late April. Proper sowing in early stage will help the silyans to take root first, then grow seedlings, develop roots, and plant Miaowang to increase production. However, it is not too early to prematurely freeze the seeds and fail to reach the depth. The ground temperature is low and the seedlings grow slowly, which is not conducive to keeping seedlings. (4) sowing method 1 live broadcast. The artificial ridges are planed pits, pits 20-30cm, depth about 8-10cm, diammonium phosphate 3g per hole, earth covering 4cm, and then 3-4 seeds per pot, then cover soil 3-4cm. If the weather is dry, you can sow the water, generally 667 square meters sowing 0.5kg or so. It is also possible to manually ditch the ridges, fertilize and cover the soil, sowing, the seed spacing is 3-5cm, and the cover soil is 3-4cm after sowing. 2 Mechanical sowing. The soybean seeding machine was used for direct sowing on the ridge. Fertilizer box sown fertilizer was controlled within 15kg of 667 square meters of DAP. Each 1.5-batch seed was mixed with 1.5-fold fried wheat, which was to be sown with uniform direct seeding. Generally, 0.5kg of seeds were used for 667 square meters, and 0.75kg of cooked wheat was used. . The western region can also use seeders for sowing, spacing 60 cm, spacing 3–5 cm, and 667 square meters with a seed quantity of 0.6 kg. 3 nursery. 120cm wide seedbed, 667 square meters of organic fertilizer 5000kg, 15kg of diammonium phosphate, evenly mixed into the bed. In the bed by 10cm row spacing 4cm deep ditch, seeding 2cm broadcast sowing, and then cover soil, water, cover a small shed. After the milk thistle emerges, it is necessary to pay attention to the removal of weeds. Can also be used in the plastic shed nursery tray seedlings, put 2-3 seeds per acupoint. 4 transplanting. It can be moved into the field in early May. On the ridge, the planters are planted at a spacing of 20-30 cm, and 1 g of urea is mixed with the soil. The seedlings, cover soil, water, and then soil are applied. Because milk thistle is a straight root system, it is necessary to excavate more soil with more soil than seedlings, and seedlings should not be too large. Transplanting less branches, the density can be appropriately increased, each pod can be planted 2-3 strains. 5 density. Under general cultivation conditions, 2000-5000 strains of 667 square meters of preserved seedlings were produced. In more fertile land, about 2,000 m baomiao of 667 m 2 in the south of Heilongjiang Province, about 3,100 in the middle and about 4,500 in the north, about 3,000 m 667 m of 667 m 2 in the southern part of Heilongjiang Province and about 4,200 in the middle in infertile lands such as loess and sand. About 5,500 in the north. If the broadcast period is postponed, the density will increase. Harvesting machinery in large areas in the central and northern regions, planted from May 20 to June 5, 667 square meters of seedlings can be increased to 12,000 - 15,000 strains.

Ear tags are used by the livestock producer to keep production records of bloodlines, birth dates, vaccinations and other key criteria necessary for raising animals as a career. Without some form of identification, it would be impossible to manage the records of each animal, especially when entire herds are raised by one person or family.
