Covering straw (grass) Before winter, in the dryland wheat row, 300-400 kg of wheat bran, wheat straw or other plant wastes are spread per acre, so as to protect the crop and prevent freezing, the soil can be improved and the fertility can be improved after corruption. It is an effective measure for dryland wheat to resist drought, freeze, and increase production. According to the measurement, the soil temperature of no-tillage wheat covered grass was lower than that of uncovered grass at noon. The soil temperature at night at 24 o'clock and at 8 o'clock in the morning was higher than that in the uncovered grass field, showing slow cooling speed and holding time. Long, small temperature difference between day and night, play a certain role in the winter cold resistance of winter wheat seedlings. Covering feces After winter wheat enters the wintering period, a layer of manure is spread along the ridge (people call it “warm ditch manureâ€), which can protect the wind, protect the earth, increase the temperature and prevent freezing, and supplement the nutrients for the young seedlings to grow green. The thickness of the manure is preferably 3 to 4 cm. When the manure is insufficient, the late barley, wheat field, sand field, and wheat field where the winter wheat is sown must be covered. Before the winter, when the wheat seedlings are about to stop growing, the roots of the soil can effectively prevent the wheat from freezing in the wintering period. The year of serious frost damage has a particularly obvious effect, generally increasing the yield by 5% to 10%. . When spraying chilling damage of Chlormequat in winter wheat, spray the wheat seedlings with 0.3%～0.5% Chlorhexidine solution, which can inhibit plant growth and resist or reduce the occurrence of freezing injury.
Glutamic acid, is an acidic amino
acid. Molecules containing two carboxyl groups, chemical name for
α-amino-pentanedioic acid. Glutamic acid was discovered by lisuoxun in 1856, is
a colorless Crystal, fresh, slightly soluble in water, soluble in hydrochloric
acid, isoelectric point 3.22. Abound in cereal protein, animal content in the
brain and more. Glutamic acid in vivo protein metabolism plays an important
role in the process, participating in many important chemical reactions in
animals, plants and micro-organisms. Msg containing small amounts of glutamic
acid.
Function:
1.Active component for lasting moisturizing and resistance to dry
conditions of human skin.
2.Increasing the elasticity of human skin and keeping it tight and
smooth.
3.Inhibiting the formation of melanin remarkably.
4.Keeping pH balance of human skin.
5.Forming a slow-release delivery system and therefore improving the
absorption capacity of nutrients in cosmetics.
6.As a humectant, moisturizer to improve skin care quality, as a
whitening agent, has anti wrinkle property which gives long lasting effect.
