Characteristics and cultivation techniques of sGK321

sGK321 (national double-value insect-resistant cotton No. 321) contains two insect-resistant genes (BT+CPTI), which was selected by Hebei Shennong Hi-Tech Co., Ltd. In March 2001, it was approved by the Hebei Provincial Variety Approval Committee. It is currently the only two-valid insect-resistant cotton variety that has passed the variety certification. Characteristics sGK321 is a mid-maturing variety, the first fruit branch has a higher birth point, and it is known as “high-tucked cotton”. It has good permeability and little rotten bells. The roots are well developed and have strong drought resistance. Strong growth and tall plants. Strong aftergrowth, high yield. Fiber quality is excellent. Boll weight 5.0 grams, the percentage of clothes 38-40%. Fusarium wilt resistance, Verticillium wilt resistance. sGK321 adopts the seed coating agent (Gao Qiao + Miao Sheng) produced by Bayer AG of Germany, which can effectively prevent seedling mites and disease. Cultivation Techniques 1. Sowing Date and Density: The mulch cotton will be sown on April 15-20, and the live cotton field will be sown on April 25-30. Sow 3-4 days before sowing, planting under the seed, dry seeds live. The sowing depth is preferably 2-3 cm. If sowing in dry land is required for sitting water, it must be sown after the water is soaked to avoid affecting germination. Seedlings transplanting: nursery in mid-April, transplanting in mid-May. Generally, planting density of high-water fertilizer land is 1700-2000 per mu, medium-low fertility is 2200-2500, and row spacing is generally not less than 100m. Such as wide and narrow rows of plants, narrow rows of not less than 60 cm. Intercropping of gourd cotton intercropping is generally 1300-1500 strains. 2, water and fertilizer operations: Shizujifei, increased potassium fertilizer, re-application of flower bell fertilizer, make-up cover top fertilizer. General Mu Shiji Diammonium Phosphate 25 kg, urea 20 kg, potassium chloride 15 kg, organic fertilizer 3-5. Early flowering topdressing urea 20 kilograms, the end of July, early August acre top fertilizer urea 5-8 kg. 3. Chemical control: sGK321 is insensitive to shrinkage, and should be increased in dosage and applied early. Usually at least at the bud stage, early flowering stage, flower and boll stage, spray once, the dosage is 2 grams, 3 grams, 4 grams respectively. Dry land and barren land should be used as little as possible. 4, pest control: any insect-resistant cotton is not insectless cotton, when the second instar larvae more than 20 larvae / 100 plants, should be promptly controlled. Although sGK321 uses Bayer's excellent seed coating agent, it is also necessary to prevent and control a single roundworm before wheat harvest to reduce the damage of other pests. 5, pruning: general planting density of 2500 or so, can go crazy, wipe buds in time, so as not to shade the field, bud, bell, resulting in reduced production. Planting density per acre of about 1500, you can use the entire growth period is not pruning, not hiccups, do not wipe sorghum leaves, only in each strain to stay close to the fruiting branches of vegetative shoots, on July 20 to hit all the top, On the 10th of August, you can hit all the group's tip (you can not hit the tip of a thin, dry cotton field). In addition: sGK321 should not be planted in severely afflicted areas, nor should it be interplanted with plants susceptible to cotton bollworm to avoid transfer of harmful cotton to older larvae.

Some common disposable surgical medical products include:
1. Surgical masks: used to cover the mouth and nose of medical staff during operations to prevent the spread of germs.
2. Surgical gowns: Medical staff wear these to protect their clothing from contamination during surgery.
3. Surgical Gloves: Healthcare providers wear these gloves to protect their hands from contamination during surgery.
4. Surgical Drape: Used to cover the patient and create a sterile field around the surgical site.
5. Surgical needles: Used to suture incisions and wounds during surgery.
6. Scalpel blades: These are used to make incisions during surgery.
7. Surgical Forceps: Used to grasp and manipulate tissue during surgery.
8. Surgical catheters: These catheters are used to drain fluids from the body during surgery.

Overall, single-use surgical medical products are critical to maintaining a sterile environment and preventing the spread of infection during surgery.
