The Characteristics of Zhongyuan 98-68 Wheat and Its Cultivation Techniques

Zhongyuan 98-68 is a state-approved wheat variety with high nutrient content and very good quality. It belongs to a multi-purpose high-quality medium-gluten national trial wheat variety. Its advantage is that it has a particularly strong tillering power and saves seeds; it has a long sowing date, and it solves the problem of early freezing and sowing of late sowing in production; the white flour, whether it is steamed bread, glutinous noodles or dumplings, tendons Degree of palatability is very good, deeply welcomed by consumers; good yellowing, strong lodging resistance; very suitable for rural small mechanical processing. The characteristics of this variety and its supporting cultivation techniques are as follows:

First, the characteristics of the characteristics of hemp, mature period than the control of Yumai 49 as early as 1-2 days, strong tiller. Plant height 80-85 cm. The plant type is compact, the ear layer is neat, the spindle type spindle, long awn, white shell, white pellet, and grain silty. Stem has good elasticity, resistance to disease, resistance to lodging, and good cold resistance. The mixed samples were measured in 2002/2003: bulk density of 778/792 g/L, protein content of 15.0/13.7%, wet gluten content of 35.6/31.3%, sedimentation value of 34.7/32.8 ml, water absorption of 55.3/54.3, and dough temperature of 3.1/. In 3.8 minutes, the maximum tensile resistance is 175/200E.U and the stretching area is 43/48 cm 2 .

Second, suitable areas and production levels are suitable for planting in the middle and early middle and high-yield areas of high-yield water in Henan, Anhui Province, northern Anhui Province, northern Jiangsu Province and Shaanxi Guanzhong region. This breed won the first place in the national production test in 2004 and it passed the national examination and approval in 2009. Generally 500-550 kilograms per mu. Under high-yield conditions, there is a production potential of more than 600 kilograms per mu. In the late period of wheat growth in 2008, the Shaanxi Guanzhong region encountered a relatively severe arid climate. Caodu, a three-point village in Lingqian Township, Sanyuan County, was planted with an average yield of 1,251 kilograms; Caoyou, Yaotou, Datong Town, etc. Mu, with an average yield of 1126.6 kilograms per mu, and Liu Sunke in Chengguan Town planted 15 mu, with an average yield of 1194 pounds per mu.

Third, the cultivation techniques

The suitable sowing date for the sowing date is October 5 to November 25. The best sowing date is October 10 to October 25. In this way, farmers have plenty of time to fertilize the soil, and Zhongyuan 98-68 is the most suitable and high-yield corn rotation, which is conducive to the promotion of wheat late seeding and corn late harvest techniques.

Due to the strong fertility of this species, sowing should strictly control the sowing volume, 7-8 kilograms per mu. However, the amount of sowing should be appropriately increased for plots that are sowed late and returned to the field. It is advisable to control the number of acres per mu in 411-430 thousand. Advocate machine broadcast, to prevent spread.

Irrigation stalk returning and rotary arable crops due to loose soil and loose soil, seed and soil are not closely combined, affecting the eruption of wheat secondary roots and wheat seedling growth, should be irrigated once after wheat sowing stumbling water solid soil or early freezing water to protect the seedlings overwinter . Spring seasoning jointing, heading and flowering, filling water. Should not be poured wheat yellow water.

In principle, the combination of organic fertilizer and inorganic fertilizer, nitrogen, phosphorus, potassium, nitrogen and phosphorus potassium, promote soil testing and formula fertilization, improve fertilizer utilization. Taking the target yield of 500-600 kilograms of middle and upper fertility as an example, 3000-4000 kilograms of organic fertilizer in Mushi, 12-16 kilograms of pure nitrogen, 9-12 kilograms of phosphorus, 6-8 kilograms of potassium, and 1 kilogram of biological fertilizer. Organic manure, total phosphorus, potassium, and bio-fertilizer are used as base fertilizers. 70%-80% of nitrogen fertilizers are used as base fertilizers, and 20%-30% are used as top-dressing fertilizers.

Diseases, Insects and Weeds Prevention and Control In the middle to late December and early December, when the average daily temperature is 10 degrees, the 1.0-1.5-gram super mu is used to control wheat fields and weeds when sprayed with 25-30 kg of water. Use coated seed or seed dressing before sowing to prevent and control ground pests in wheat fields. When the golden needleworms, cockroaches and cockroaches are serious, the mu is mixed with 3% carbofuran and mixed with manure; 50% of phoxim is used for water 10 times, and 500 kg of fine soil is sprayed to form toxic soil. . In the mid-wheat period, the use of 25% triadimefon 60 grams of water control stripe rust, powdery mildew. During the flowering period of wheat, 40% of carbendazim 400g sprayed 50 kg of water on the control of head blight, and the amount of spray on the straw returned to the field increased. Wheat aphids and wheat spiders were treated with 40% of Dimethoate EC.

The field management manages all seedlings before winter and cultivates strong seedlings to keep the seedlings safe for the winter. In the middle period, measures such as early cultivating and cultivating land are used to attack the main culms of strong culms. The main goal of the latter stage is to increase the weight of roots and leaves, combine 0.25 kg of urea plus 1 kg of potassium dihydrogen phosphate and 25 kg of water to prevent and treat 2-3 times of disease.

Hyaluronic Acid Eye Drops Sodium Hyaluronate (HA), Pure Hyaluronic Acid could be used in eye surgery, such as Hyaluronic Acid Eye Drops, corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment.

Eye Drop Grade Hyaluronic Acid Powder is an important component of intercellular substance, eye vitreous body, joint fluid and other connective tissue. It acts the important physiologic roles in holding body's moisture, maintaining extracellular space, adjusting osmotic pressure, lubricating and promoting cells to repair in the body. Sodium Hyaluronate can be used as viscoelastic agent inintraocular lens implantation operation, as the filler in the osteoarthritis and rheumatoid arthritis and otherjoint surgery, as a medium widely used in eye drops, it also can be used to prevent postoperative adhesion and facilitate the wound heal. The compounds formed by the reaction of Sodium Hyaluronate with other drugs play a drug release effect role, thus achieve the purpose of drug targeted and time controlled release.

With the development of medical technology, Sodium Hyaluronate has been more and more widely used in medical applications. In 1976, Sodium Hyaluronate was first commercialized and used as ophthalmic viscoelastic agents, which is a significant progress in the ophthalmic industry. In 1987, Sodium Hyaluronate for intra-articular injection came in to the market. In 1990s, the large-scale production of Sodium Hyaluronate by fermentation made the cost lower, thus products containing Sodium Hyaluronate such as eye-drops, dermal fillers and other Sodium Hyaluronate preparations started to be used extensively.
