Burst Management

According to the law of fattening need and the fertility process, timely re-applying tree-fertilizer is the key measure to meet the first peak of sucking. The fat in this area is generally applied in early June. Each per acre will be fermented with 2000-2500 kg of organic fertilizer and 30-40 kg of compound fertilizer with a high concentration. The organic fertilizer should be kept at a distance of 15-20 cm from the seedlings. The fertilizer should be prevented. Damaged root seedlings. After the fertilization, it is timely to clear the ditch, which will not only improve the utilization rate of the fertilizer, but also improve the environmental conditions of the earthworm. The suitable temperature of the rooting stage is 25-35 degrees. The temperature in this period is sufficient for the growth and development of the seedlings. The main contradiction is the management of fertilizers and water, and the growth of fertilizers is sufficient. This period in the water management, neither dripping nor drying, rainy season, rainy season should pay attention to clearing the ditch to prevent waterlogging; hot and dry season sunscreen. Irrigation is the main measure to solve this contradiction, using flat ditch water to moisten the soil, prevent flooding and flooding, and pay attention not to water at noon. Earthworms play a very important role in the growth and development of Bulbil. On the pit? R soil is conducive to improving the shape of the earthworms, and promote root growth, but we must pay attention to earth can not be too much too thick, otherwise it will hinder the roots of the breath, and petiole elongation, reduce commodity, general soil requirements of 10-12 cm is appropriate . Earthing should be carried out when the soil moisture is moderate, and it is easy to operate. The earth soil should be finely crushed, and the earth should be uniform so that the earthworms can grow normally and grow properly. When the soil is cultivated, part of the root system is damaged, and once the soil is cultivated, water can be irrigated once to promote normal growth and development. In the middle and late June, the key time for the prevention and treatment of diseases such as epidemics is prevention, prevention and control. Use preventive medicines: Anti-viral drugs, 500-600 times of metalaxyl MnZn, and control agents: 1000 grams of Prec.

Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages, and on hydrolysis give the constituent monosaccharides or oligosaccharides. They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch and glycogen, and structural polysaccharides such as cellulose and chitin.

Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more than one type of monosaccharide is present they are called heteropolysaccharides or heteroglycans.

Natural saccharides are generally of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. Examples of monosaccharides are glucose, fructose, and glyceraldehyde. Polysaccharides, meanwhile, have a general formula of Cx(H2O)y where x is usually a large number between 200 and 2500. When the repeating units in the polymer backbone are six-carbon monosaccharides, as is often the case, the general formula simplifies to (C6H10O5)n, where typically 40≤n≤3000.

As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units; but the precise cutoff varies somewhat according to convention. Polysaccharides are an important class of biological polymers. Their function in living organisms is usually either structure- or storage-related. Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called "animal starch". Glycogen's properties allow it to be metabolized more quickly, which suits the active lives of moving animals.

Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms, and is said to be the most abundant organic molecule on Earth.It has many uses such as a significant role in the paper and textile industries, and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose. Chitin has a similar structure, but has nitrogen-containing side branches, increasing its strength. It is found in arthropod exoskeletons and in the cell walls of some fungi. It also has multiple uses, including surgical threads. Polysaccharides also include callose or laminarin, chrysolaminarin, xylan, arabinoxylan, mannan, fucoidan and galactomannan.
