No-tillage rapeseed has the characteristics of saving labor and production, high yield and high efficiency. According to the survey, no-tillage rapeseed can save about 6 workers in transplanting than nursery transplanting, and the operation is simple and yield is basically the same. It is an effective measure to develop effective agriculture and expand the planting area of ​​rapeseed. The cultivation techniques are described as follows: First, the use of double-low rapeseed varieties: At present, the promotion of double-low rape varieties: Zhejiang Shuang 72, Huyou 15. Zheshuang 72 has the characteristics of resistant to late broadcasting. Shanghai Oil 15 has a higher output. Therefore, it is flexible to choose according to different sowing dates. Second, soil preparation and sowing: No-tillage rapeseed direct seeding after harvesting in late rice, conditions and strive to sowing, sowing time is generally before the end of October, at the latest not later than November. As weeds and rape seedlings grow synchronously, weeds are heavier. According to the growth status of weeds in the field after the harvest of the late rice, 5-10 days before sowing, 500 ml of 10% glyphosate, or 100 ml of 41% of Roundup, and 50 kg of water were sprayed. For the first time weeding. Before the site preparation, 1500 kg of organic fertilizer or 10 kg of urea, 7.5 kg of chlorinated potassium, and 0.5 kg of borax were used as base fertilizer. The soil is 2 to 2.5 meters wide. It is also possible to use the high-yielding ditch in the paddy fields and to make rakes in the ditch. Gully smashed on the sorghum surface, sowing can be broadcast or horizontal seeding, broadcast broadcast width 20-30 cm, spacing 40 cm, 0.3-0.5 kg per mu, so that the quantitative ration, with a small amount Coke dust or fine mud is mixed for uniform sowing. Third, the field of fertilizer management, prevention and treatment of diseases and weeds when the seedlings after 1-2 true leaves when the thinning, weak to stay strong, 3-4 true leaves when the Dingmiao. As the growth of live rapeseed is relatively small, it is appropriate to increase the density. The basic seedlings per acre are controlled at 1.2 to 15,000 strains. The seedlings are to be applied after fixing the seedlings, and urea is applied 5-7.5 kg per acre. According to the situation of field weeds. During the 4-5 leaf stage of rapeseed, use 30% Shuangcaojing 75-100 ml per mu, or 40-60 ml per mu, or 10.8 per cent per mu with 30. Spray, weeding the second time. From the end of December to mid-January, the fertilizer is applied in a fertilizer of 7.5-10 kg of urea per acre. By the end of February, apply moss fertilizer with 6-8 kg of urea per acre, spray a concentration of 0.3% borax again to prevent flowering. In the middle of March, Miao Shizhuang was used as a manure fertilizer during the flowering period, and 0.2% potassium dihydrogen phosphate and 1-2% urea solution were sprayed outside the root to increase the seed setting rate and increase grain weight. The management of water slurry will focus on the increase of rainfall after the spring, timely clearing drainage, and preventing waterlogging and premature aging. Pest control The seedling stage of rape should pay attention to the control of aphids and cabbage caterpillars. Early flowering and flowering should focus on prevention and control of Sclerotinia. While clearing the gutters, reducing the humidity in the field, and improving the microclimate in the field, 40% of sclerotium net carbendazim drugs are used for prevention and treatment. 4. Timely harvesting When 80% of the whole field fruit is yellow, the main grain is black when harvesting is appropriate to prevent cutting green.
Functional Oligosaccharide
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
