The “early spring peppers, summer watermelons and autumn peas†model can make full use of land, climate and labor resources to increase the multiple cropping index of the land. After this model was successful, it was demonstrated and promoted in many places, and achieved good economic benefits and increased the income of the majority of growers.
1. Early spring peppers, early spring peppers are planted in late October, transplanted in early February of the next year, listed in early April, and harvested in late June.
Improve the seedbed, build the shed, timely broadcast in time, cultivate strong seedlings, apply sufficient base fertilizer, timely planting, timely topdressing, planting pepper seedlings , rational irrigation, comprehensive prevention and control of pests and diseases.

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
