Irrigation of jasmine
Jasmine likes to be moist and is afraid of drought and waterlogging. Drought often makes jasmine leaves curl, leaf color fade, chlorophyll is destroyed, synthase activity decreases, decomposing enzyme activity increases, not only can not synthesize nutrients needed in the process of cell division, on the contrary, proteins in the body are hydrolyzed into amides and amino acids, causing plant metabolism disorder. The water content of jasmine buds and shoots is more than 80%. Water shortage and water loss will inhibit or even destroy the normal physiological and biochemical processes of the plant. Growth and development of jasmine plants during severe drought

Propagation methods of Jasmine Flower
1. Striping propagation is to press the middle part of the jasmine plant into the soil by using the sprouting branches or shoots with a certain length in the lower part of the jasmine plant, so that it can produce new roots and become independent new plants after cutting off the mother branch. The premise is that there must be a jasmine mother tree, and each clump of mother tree can not press many branches, can not meet the supply of a large number of seedlings, generally use potted plants and lack of ponds to supplement seedlings. two。 The branch propagation of jasmine is a tufted shrub, and many adventitious roots can be produced in the rhizome. Biennial plants often have several stem branches.

Storage of finished jasmine tea
The main factors affecting the quality of jasmine tea during storage are temperature and water content, oxygen and light. In general, the greatest influence is tea water content.

The moisture content of finished jasmine tea is close to 8%. Therefore, it is more sensitive to humidity, and the relative humidity of the surrounding environment directly affects the moisture absorption rate of tea. So bulk jasmine tea is best stored in
