Sowing variety selection. The spring planting bitter gourd generally has a long harvest period and should use strong branching and good heat resistance. Soak germination. The bitter gourd skin is thick, it is difficult to absorb water, and it is difficult to germinate. Can be used hot water first, wait until the natural cooling after soaking more than 12 hours. sowing. Put the well-matched nutritious soil into the seedbed with a soil thickness of about 10cm, soak the water and broadcast the seed directly to the nutrient soil. After sowing, cover the earth about 2 ~ 3cm, and then spray a new high-fat membrane protection, can activate the surface hardening density, improve the emergence rate.
Manage seedling management. Appropriately reduce the temperature after emergence, the seedbed temperature maintained at 25 °C ~ 30 °C, 15 °C ~ 18 °C at night, moderate watering to maintain soil moisture. Timely weeding, ventilation, moisturizing, timely spray sterilization to prevent disease. Seedlings have 2 to 4 true leaves that can be transplanted and colonized. About one week before planting, the seedlings were made. Colonization. Planting period is usually carried out when soil temperature is stable above 12°C, but planting should be done as early as possible. The depth of planting seedlings was revealed by the seedlings cotyledon.
romatographic and use double-antibodyromatographic and use double-antibodysandwich method to detect antigen. Whenthe concentration of antigen in specimen ishigher than the minimum detection limit, theviral antigen will form complexes withlabeled antibodies first. Under chromatogra-phy, the complexes move forward along thenitrocellulose membrane till captured bypre-coated monoclonal antibody ofindetection zone.Through the visible color tointerprete the test results.
