1. Scientific selection: Walnuts are suitable for growth in sandy soils and black loam soils with warm soil, deep soil layers and good drainage. They should be planted on sunny slopes and leeward. The newly planted young trees should have sufficient water and fertilizer, and spray a new high-fat film to insulate the moisturizing and anti-pathogenic bacteria, shorten the slow seedling period and accelerate the development of roots.
2, preserved flowers and fruits: in the flower bud stage, young fruit stage and fruit expansion period, spray strong fruit tingling, increase the fruit pedicle, increase the nutrient transport, reduce the fruit drop, improve the pollination ability, improve the fruit set rate, Speed ​​up the expansion to ensure high quality and high yield of fruit. The size of the fruit in the tree makes the tree unbalanced, affecting both the balanced income and the health of the orchard. It is necessary to brush the foliar fertilizer once a year during the flower bud differentiation period, which can promote flower bud differentiation and inhibit the summer shoots, which can increase the pollination ability and fruit set rate.
3, disease prevention: walnut silkworm moth, walnut limb moth, walnut fruit like a nail. The main diseases of walnuts are: walnut black spot and walnut blight. Control and spray targeted drugs to kill. At the same time, it is necessary to spray the tree to protect the tree generals.

INTENDED USE
The One Step HCG Pregnancy Rapid Test Kit is a rapid
chromatographic immunoassay for the qualitative detection ofhuman chorionic gonadotropin (HCG) in urine to aid in the early
detection of pregnancy.
PRINCIPLE
The test utilizes antibodies including a
monoclonal HCG-β antibody and goat anti-mouse IgG on thenitrocellulose membrane with colloidal gold marked anti-HCG-α
monoclonal antibody as an mark tracer. The reagent is used to
detect the HCG in urine according to the principle of double
antibody sandwich method and gold immunochromatography
assay
There is a control line (C) controlling the reaction process shown
on the coated film. Based on test line`s (T) appearance to
determine whether the tested sample contains HCG (Human
Chorionic Gonadotrophin) or not.
MAIN COMPONENTS
Basic components: Sample pad, colloidal gold marked pad,
nitrocellulose membrane, absorbent paper and PVC board.
SAMPLE REQUIREMENTS
A urine specimen must be collected in a clean and dry container. A
first morning urine specimen is preferred since it generally
contains the highest concentration of HCG, however, urine
specimens collected at any time of the day may be used. Urine
specimens may be stored at 2-8℃ for up to 48 hours prior to assay.
For long-term storage, specimens may be frozen and stored below
-20℃, the frozen specimens should be fully melted and restore to
room temperature and shake before testing .Urine specimens
exhibiting visible precipitates should be centrifuged, filtered, or
allowed to settle to obtain a clear specimen for testing.
