Jujube spring planting survival rate is high
In early April, it was the best time to plant jujube trees in the northern region. Because jujube buds sprout at 13 ° C to 14 ° C, the roots begin to move around 20 days before germination. Choose a strong seedling root seedling to have a 20 cm mother root and 5 to 6 fine roots of 2 mm in diameter, and the seedlings should have 6 to 8 lateral roots. The seedling height is more than 1 meter, the shoot tips are well matured, the top buds are fully developed, and the whole plant has no pests and diseases. Before planting, the seedlings were immersed in a 50 mg/kg naphthaleneacetic acid solution + a new high-fat membrane for 8-12 hours to isolate the virus infection, strengthen the respiratory intensity, stimulate growth, and promote rooting of the cuttings. The diameter of the jujube planting planting hole is about 1 meter, and the excavated soil should be piled separately. When planting, the bottom of the hole is first covered with gasket fertilizer or mixed with compost, then the jujube seedlings are placed in the hole to help the layering and filling. The depth of planting seedlings is based on the impression of the original seedling roots. Pay attention to fill a layer of soil and practise a layer to make the roots close to the soil and finally fill the water. At the same time, the ground and Miaoxiu spray a new high-fat film 600-800 times liquid to protect the water-proof evaporation, anti-soil layering, suffocation and isolation of pests and diseases, effectively prevent the ground water from evaporating, the seed water does not transpiration, shorten the slow seedling period , quickly adapt to the new environment and grow healthily.

This test provides a preliminary result only. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas
chromatography (GC) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any result, particularly when
preliminary positive results are indicated.
The Alcohol Rapid Test Strip (Urine/Saliva) is a chemical assay based on an alcohol-sensitive enzymatic reaction. Alcohol, if present in the specimen, reacts with
chemicals on the reaction pad and causes a color change.
The Alcohol Rapid Test Strip (Urine) consists of a plastic strip with a reaction pad.The reaction pad employs a solid-phase chemistry system which uses a
highly specific enzyme reaction. On contact with specimens of alcohol, the reaction pad will rapidly change colors depending on the concentration of alcohol
present. This color change is proportional to the concentration of alcohol in the specimen. By comparing with the color blocks on color chart, an approximate
