After the wheat enters the returning green stage, it enters the sensitization stage from the temperature-sensing stage, and the cold resistance of the wheat seedling is significantly reduced. Once the cold is encountered, the plants are vulnerable to freezing injury. To this end, following the management of early spring wheat, introduce several effective antifreeze methods.
Scratch ploughing in the soil back to the top sparse Ling Ling, you can loosen soil, protect the earthworms, warming, weeding, and enhance the ability of wheat seedlings to keep out the cold. According to observations, the average ground temperature within a 5cm soil layer during daytime is generally increased by 0.5°C to 1°C in 7 to 10 days after a row. It is very beneficial to promote root development and nutrient conversion. Therefore, regardless of weak seedlings, strong seedlings, or strong seedlings, they must pay close attention to cropping up during the spring return period; for wheat fields with prosperous tendencies, they can also be properly squatted to suppress spring delivery. When ploughing, it is necessary to pay attention to grasping the shallow ridges and fine ridges, and push the rakes and rakes along the side while pushing; if the repression is carried out before the ploughing, the soil will not empty, and thus the effect of lifting the ridges and lifting the ridges will be received.
In the early spring, the suppression of wheat field repression can crush the rubbish to close the cracks and make the roots of the wheat roots closely contact with the soil to prevent cold air from invading and damaging the wheat seedlings. At the same time, the repression also has the effect of lifting the earthworms, which can increase the moisture content of the soil surface, which is conducive to the reduction of chilling damage at low temperatures.
Fertilization of wheat in early spring fertilization can make up for winter soil fertility, increase nutrient accumulation, promote the growth of young wheat seedlings, and resist or reduce early spring freezing injury. In early spring wheat fertilization, should seize the favorable opportunity for the soil just thawing, by digging deep ditch; generally should not water, so as not to reduce the temperature, affect the growth of wheat seedlings.
Spraying medicine in the green season of wheat, spraying 20010-6 paclobutrazol solution per mu 30 to 40 kg, can inhibit the growth of wheat seedlings, enhance cold resistance.
[Composition]
The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.
[Indications]
1. Primary
agammaglobulinemia, such as X-linked hypogammaglobulinemia,
common variant immunodeficiency diseases, immunoglobulin G subclass deficiency,
etc.
2. Secondary
immunoglobulin deficiency diseases, such as severe infection, septicemia of
newborn, etc
