Ricinus cultivation techniques
Ramie root system is well developed, with thick straight roots and 3 to 7 large lateral roots. The straight roots are as deep as 2 to 4 meters, and the lateral roots are flat up to 1.5 to 2 meters. The ability to adapt to the soil is strong, generally the soil can grow as long as the water is well drained; the requirements for the front crop are not strict; the technical requirements for cultivation are simple: in the thin and thin ground, high economic benefits can be obtained, and they can engage in arable land. Dry cultivation can greatly increase the yield and benefits.
The ramie hybrids we bred and promoted are mainly ramie No. 1~6, among which ramie Nos. 1, 2 and 5 have passed the approval of the Provincial Crop Variety Approval Committee. The large-scale experimental demonstration shows that the production can be greatly improved, and it has characteristics such as resistance to drought, flooding, salt and alkali resistance, and has strong adaptability. Almost all the arable land can be planted except for alfalfa. The medium-sized land mass generally produces 250-300 kilograms per mu, and the high-yield parcels are 350 kilograms or more.
Sowing: The sowing time is between March 20 and early May. There are two ways of live broadcasting and interplanting. The seeding is planted when the ground temperature rises to about 5°C; the seeding is planted 10~25 days before the harvest of wheat, garlic, onion and other crops. The spacing is 90-150 cm, the spacing is 60-100 cm, and the density is 600-1200/mu. Live broadcast should be thin, interplanting should be dense; fertilizer should be thin, dry and thin land should be dense. Each seed sowing 3 seeds, covering the depth of 4 to 5 cm. In order to ensure that all seedlings are planted once, they should be planted adequately, and digging holes and watering should be used for sowing.
Film Coverage: Plastic film coverage is an effective measure to increase output and save investment (manual weeding, watering, etc.). Covering an acre of plastic film only needs to invest 20~30 yuan, generally can increase production by more than 30%.
Check seedlings, fill seedlings, Dingmiao: Castor seedlings in the seedling stage (3 true leaves before transplanting) is easy to survive, found that the lack of seedlings to transplant seedlings in a timely manner. Dingling seedlings were carried on 3 to 4 true leaves, leaving 1 plant per hole. Dingmiao too late to form weak seedlings, affecting production.
Fertilization: Fertilization can greatly increase production. The base fertilizer is generally 15 kg of urea, 10 kg of diammonium phosphate, 7 kg of potassium sulfate, and 1000-2000 kg of farmyard fertilizer. Fertilizer applied at the bud stage of the first main spike, applying 10-15 kg of NPK fertilizer.
Overall: Pruning is an important measure to increase production. The first flower was budded before bud emergence, and 2 to 3 first-level branches were kept under flower, and the remaining branches were all wiped off. Afterwards, depending on the growth of the plants, the number of branches left on the second, third, fourth, and fifth branches was determined. When sowing is late, the production can be greatly increased by adopting three varieties of large spike type, increasing density, and pruning. The density increased to 1000 to 1500 strains. One strain only retained 4 to 5 branches and all other branches were removed.
Harvesting: 80% of the pods on the ear are harvested when the tan is brown and harvesting is not premature, so as not to affect the yield and quality. After harvesting, it can be bagged and sold in a timely manner when it is air-dried and threshed, and the moisture content drops below 9%.
Different from absorbing the medicine through intestine, with Infusion and Injection ,medicine is more quickly integrated into the blood stream, thus allowing it to work faster and more focused. Injections and infusions are strictly carried out with disposable products, so as to avoid cross contamination and prevent infectious transfers. The application of injections can take place in a variety of manners. However, most involve subcutaneous, intramuscular or intravenous methods.
In the Infusions/Injections category, Yingmed offers you everything you need for injection and infusion procedures: Syringe , Cannula, Disposable Infusion Set, Infusion Stand.
In order to avoid infection,some disinfection products must be used before or after puncture, such as Cotton swab,Povidone-idoine swabstick , Cotton ball, Alcohol pre pad, Povidone-idoine prep pad , Non-woven surgical tapes, Infusion plaster, IV cannula dressing, Alcohol Prep Pad and ect. You will find these items in the category of Yingmed Wound Dressing .
