The common disease in the growing period of the lotus is brownish-brown disease, which is mainly harmful to the vertical leaves. It is caused by the infection of Alternaria solani, the other is spot blotch, and it also damages the vertical leaves. It is caused by the fungal spore spotting. The disease symptoms of the two disease burdens are very similar, and they are connected by patches to expand the plaque and make the mesophyll green and yellow. Most of them are concentrated in the onset of the rainy season, mainly due to high temperature, high humidity, weak lotus growth, and poor lighting conditions. In severe cases, it can be used as 800 times as high as 500-times dose of dexamethasone or thiophanate solution plus a new high fat film. Based on prevention, timely removal of diseased leaves and spraying of general tree guards to disinfect and sterilize.
Insect pests generally have locusts, scarabs, moths, etc. The maggots are more powerful. They have more than 20 generations in 1 year. The nymphs and adults cluster on leaves, petioles, and young buds. They are harmed by sap and can spray Beijing Green 1000 times. Off. A small amount can be hand-kneaded or sprayed frequently during daily watering.
Human chorionic gonadotropin is a hormone for the maternal recognition of pregnancy produced by trophoblast cells
Human chorionic gonadotropin (HCG) is a glycoprotein secreted by trophoblast cells of the placenta And β dimer proteins. The molecular weight of glycoprotein hormone 36700, A. Pituitary, FSH, follicle stimulating hormone, LH (luteinizing hormone) and TSH (thyroid stimulating hormone) are basically similar, So they can cross-react with each other, while the structure of β subunit is not similar. In mature women, the fertilized ova move to the uterine cavity for implantation and form embryos. In the process of development and growth into the fetus, the placental syncytiotrophoblast cells produce a large amount of HCG, which can be excreted into urine through the blood circulation of pregnant women. Serum and urine HCG levels rise Rapidly from 1 to 2.5 weeks of gestation, reaching a peak at 8 weeks of gestation and dropping to moderate levels at 4 months of gestation, which remain at the end of gestation. At present, the commonly used detection methods are: latex aggregation inhibition test and hemagglutination inhibition test; Radioimmunoassay (RIA); Enzyme linked immunosorbent assay (ELISA); Monoclonal antibody colloidal gold test
