Buckwheat planting

Seeding method China's buckwheat planting area is vast, the terrain, soil quality, cropping system and farming cultivation level of production areas are very different, so the sowing methods are also different. The main methods are seed drilling, on-demand broadcasting, and sowing. Scientific cultivation of buckwheat should advocate drilling. The sowing was caused by uneven seeding, irregular seedlings, poor ventilation and light transmission, and inconvenient field management. As a result, the yield was not high. On-demand work is too laborious. The quality of sowing seeds is high, which is conducive to the rational close planting and the coordinated development of individuals and individuals, so that the yield of buckwheat can be improved. According to the Liangshan Prefecture Agricultural Experiment Station of Sichuan Province, bitter buckwheat adopts both on-demand and on-demand broadcast production, which results in an increase in production by 20.34% compared with sowing and an increase of 6.89% on-demand on sowing. Drill seedlings are mainly seedling and ploughing of animal traction. According to the division of soil fertility and species, the seedlings were divided into narrow rows and wide rows, spaced 25-27 or 33-40. The advantages of drilling are the same in depth and depth, evenness, and neat emergence. When the spring drought is severe and the lyrical condition is poor, the seeds can be sown and planted at the right time to ensure the whole seedlings. Drilling also facilitates field management of weeding, weeding and topdressing. It is better to use the north and south ridges for drilling. On-demand, on-demand use of open hole, artificial seed, this method in addition to artificial seeds difficult to control the amount of seeding, the number of points per acre is not easy to grasp, the use of nutrient area is not uniform, but also more laborious. After spreading and sowing in wheat in some areas such as Gansu Jidong and Shaanxi Yubei, the first arable land was then sprinkled with seeds and then picked up. Due to the spread of no plant spacing, the density is difficult to control, the population structure in the field is irrational, and the thick place becomes a pile. The seedling is not found in the thin place. Field management is difficult and production is generally low.

[Composition]

The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.

[Indications]

1. Primary agammaglobulinemia, such as X-linked hypogammaglobulinemia, common variant immunodeficiency diseases, immunoglobulin G subclass deficiency, etc.

2. Secondary immunoglobulin deficiency diseases, such as severe infection, septicemia of newborn, etc

3. Autoimmune diseases, such as primary thrombocytopenic purpura, Kawasaki disease
