Disposable Piercing Guide - WPTC5 A Disposable Laparoscopic Trocar is a medical device used in minimally invasive surgery to create a small incision in the abdominal wall for the insertion of surgical instruments and a camera. It consists of a sharp, pointed tip that is inserted through the skin and into the abdominal cavity, and a sleeve that provides a pathway for the surgical instruments. Once the trocar is inserted, the sleeve is locked in place and the instruments can be inserted and removed through it. Disposable laparoscopic trocars are designed for single-use only to prevent the risk of infection and cross-contamination. They are available in different sizes and shapes to accommodate various surgical procedures.

(1) Timely sowing and reasonable close planting: The timely sowing time for vegetable soybeans is around July 20th. To preserve seedlings and seedlings, it is necessary to: (1) Select a field with deep soil, medium fertility, and good drainage and irrigation conditions. "Fall Breeding" base; 2 heads of summer harvest seed should be used in the shady place shade, so that the seed moisture content of 16.7-18.5%, not high temperature spread, so that seed coat rupture damage; 3 before sowing or after sowing irrigation, with Permit the row, until the field soil water capacity reached 55-60%, sowing and meet the water requirements of seedling growth; 4 after sowing with soil miscellaneous fertilizer cover, and cover with a thin layer of straw, to prevent the rain exposed seed surface, Remove the straw after emergence. The planting specifications are narrow and narrow, with a width of 0.9 meters, one double row, hole sowing, 15 cm hole spacing, 3 seedlings per hole, 100-120 kg per hectare sowing volume (6.6-8 kg/mu) ). (2) Scientific fertilization and fine field management: The principle of fertilizing vegetable soybeans is to “split the head and protect the middleâ€. When the earthworms are used for soil preparation, the seedling trenches should be applied and 375 kg (25 kg/mu) of superphosphate should be applied per hectare. 15 tons of fertilizer (1 ton/acre) was used as base fertilizer; after two incomplete leaves were unfolded, 7500 kg (500 kg/mu) of manure was applied per hectare as top dressing; after 10 days, 75 kg of urea was applied per hectare (5 kg / Ac), potassium chloride 60 kg (4 kg / acre), flowering period on the second and third types of seedlings topdressing a fertilizer. Pay attention to irrigation on the field pipe, require alternating wet and dry seedlings, water in the sulcus, keep the soil moist during the grain-filling period, achieve stimulating, promote grain filling, pay attention to cultivating loose soil 2-3 times, to avoid soil compaction . (3) Serious miscellaneous and timely harvesting: The existing special-purpose vegetable soybean varieties will be degraded during the autumn season, and plants in the middle and small crops will appear in the fields. According to statistics, the severely degenerated planting rate in the Qiutuo field may be To reach 15%, if it is not removed in time, it will seriously affect the finished product quality of Daejeon Xian in the spring of the next year and affect the processing exports. The miscellaneous work was carried out in the middle and later stages of the granules. Through the field-by-plant inspection, it was found that the degraded plants and the miscellaneous plants were immediately unplugged to ensure the purity of the seeds. Due to the fragile nature of the autumn crops, they should be harvested immediately when 80% of the soybean meal turns brown, and tied around the 4-5 crops after harvesting to promote postharvest and improve the complete grain rate of the seeds. Good appearance and high quality. China Agricultural Network Editor
