Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.

Increased production and efficiency: The technology significantly increases production and efficiency, generally increasing production by 5% to 10%, and increasing efficiency by about 15%.
Technical points:
1. Core Technology:
1 suitable for early sowing. Huaibei semi-winter wheat varieties from October 1 to 15, pre-spring varieties from October 10 to 20, and Suzhong from Huainan are from October 25 to November 5, and early November in Su Nan, and are suitable for sowing.
2 precision semi-precision sowing. Precise sowing in the appropriate period within the use of precision sowing, the basic seedlings controlled at 6 to 120,000 / acre; late in the appropriate range of semi-precision seeding sowing, basic seedlings controlled at 12 to 180,000 / acre. According to the predetermined basic seedlings, seed germination rate, field emergence rate and 1000-grain weight and other factors, determine the seeding rate, and implement accurate quantitative seeding.
3 soil testing formula, efficient fertilization. According to the law of high-yield wheat requiring fertilizer, in order to meet the vigorous demand for fertilisers during the peak of the tillering period and the jointing and booting stage, 500-600 kilograms of wheat are produced per mu. Normally, 16-18 kilograms of pure nitrogen need to be applied per acre. Nutrient supply conditions increase phosphorus and potassium. Fertilizer application adopts "V" type two-fertilizer method, that is, full-basic fertilizer (50% to 60% of total nitrogen application, 50% of total phosphorus application, 50% to 70% of total application of potassium, and appropriate amount of basal fertilizer. Supplement Miao Miao), Pushi replanting booting fertilizer (40% to 50% of the total application of nitrogen, 50% of the total application of phosphorus, 30% to 50% of the total application of potassium), to promote strong culm culm. The jointing manipulators are applied in the inverted 3-leaf stage, ie, the paleness of the leaves fades, the height of the peak seedlings declines, and the first internodes of the base begin to elongate at the beginning of the second regular internode. Generally, the Huainan region is in the middle and early March and the Huaibei region is at 3 In the middle and late part of the month, the amount of nitrogen applied was 20% to 25%, and compound fertilizer was appropriate. The booting fertilizer was applied to the tip of the flag leaf to the breaking point, and the amount of nitrogen applied was 15% to 20%.
2 supporting technology:
1Machine uniform broadcast, improve the quality of sowing. According to the situation of cornices, soil, soil moisture, and returning straw, we actively created suitable farming conditions for planting, vigorously promoted machine seeding and even spreading of machinery, improved the quality of sowing, and achieved uniform seeding, suitable sowing depth, and consistent depth, ensuring timely Seedlings, seedlings and strong seedlings.
2 Supporting ditch system to strengthen comprehensive prevention and control of pests and weeds. A high standard set a good wheat field ditch, timely drought relief and drainage. We will focus on prevention and control of pests and diseases such as sheath blight, powdery mildew, and head blight in the autumn, spring, and the middle and late stages. Reasonable use of growth regulators to control strong growth and prevent lodging. In case of “cold winter†cold injury, it is necessary to increase the recovery fertilizer in time.
Suitable areas: High-yield areas with high soil fertility and suitable early sowing.
The promotion base in 2012: In 2012, the province promoted about 9 million mu of planting.
Expected target for 2013: In 2013, the province will promote more than 10 million mu of cultivated area.
Focus on promoting counties (cities, districts): Feng County, Pei County, Tongshan, Zhangzhou, Xinyi, Guannan, Donghai, Dongtai, Dafeng, Suining, Huai'an, Yishui, Jinhu, Taixing, Xinghua, Jingjiang, Jiang Yan, Rugao, Rudong, Hai'an and other places.
Notes: 1. According to the situation of rice cultivars sooner or later, soil texture, moisture conditions, and agricultural machinery and equipment, etc., select the appropriate mechanical sowing methods to improve the quality of sowing, and strive to survive the winter and lay a foundation for high yield; 2. Use of trenching soil Enhance the coverage of organic fertilizers, straw straw, etc., and do a good job of grassland control, is the key to ensuring the high yield of wheat.
Precise quantitative high-yielding cultivation techniques for wheat
Technical Overview: On the basis of suitable early sowing and precision semi-finishing sowing, according to the rules of quality formation of wheat high-yielding populations and the characteristics of required fertilizers, the application of precise quantitative fertilization and promotion measures will increase the seed setting rate, mainly attack large spikes and increase flowers. After the accumulation of dry matter, increase the grain weight, and achieve more than 600 kilograms per mu in Huaibei wheat area and 500 kilograms per mu in the Huainan wheat area.
