When corn fails to be sowed at the right time or suffers from natural disasters such as drought and flood in the early stage of childbirth, it will affect the growth and development of the plant, delaying its maturity. In order to timely harvest, it can be used to promote cooked method to shorten its growth period. There are many ways to promote ripening, which can be selected according to specific conditions.
Reasonable top-dressing method is to apply 10 kg of ammonium nitrate to the ditching process per acre in the silking stage of corn, or to spray with potassium dihydrogen phosphate solution at a concentration of 0.2% to 0.3%. If the silking period has been postponed, an intervening method may be adopted to reduce nutrient consumption, increase leaf temperature, and accelerate the birth process. In general, the silking period will be 2 to 3 days earlier.
The peeling and drying stick method is used to peel the loquat leaves when the seeds grow to a normal size at the later stage of corn filling, so that the seeds are exposed and the water is dried. This generally allows it to mature 4 to 5 days in advance. The whole plant drying method such as the wheat sowing period has arrived, but the corn is still not fully mature, and the corn can be chopped down and placed on the side of the field or other free space, being careful not to pile up in large piles until the leaves dry up and then remove the ear. Generally, it can increase the grain weight by about 20%.
Biochemical products are a large number of products obtained by various biological reaction processes, including, or other processes. Their common feature is that the materials mainly derived from biological sources are used as raw materials, which are formed in the bioreactor through the action, and are extracted and purified by relevant means. Some of these products can also be produced by chemical synthesis, such as, etc. Whether to use chemical synthesis or biosynthesis should be determined from the comprehensive consideration of economic technology; some products can only be produced by biosynthesis or it is more economical and reasonable to use biosynthesis , such as, amylase, vitamin B, interferon and other substances with complex molecular structures; some products are produced by both chemical synthesis and biosynthesis, such as semi-synthetic penicillin, cortisone, vitamin C, etc.
Biochemical products can be divided into:
â‘ Bulk Chemical Products, such as ethanol, acetone, n-butanol, glycerol, citric acid, lactic acid, gluconic acid, etc.;
â‘¡Fine chemical products, such as various amino acids, enzyme preparations, nucleic acid products, etc.;
â‘¢Medical products, such as various, various steroids, conventional bacterin, vaccines, etc.;
â‘£Other products, such as biological pesticides, edible and medicinal yeast, feed protein (single-cell protein), biogas, etc.; Wait.
