Seeding too early or too deep: due to the long seed emergence time, bad weather or long-term low temperature, the decline of autoimmune function, weak resistance to the virus or virus infection and yellow buds or rot.
This is related to the nature of the plot: This situation occurs mainly in low-lying land, and is lighter on highland or sunny slopes.
It is related to the type of seed coating used: Improper use of seed coating agents or too long coating time can cause corn seed to cause this phenomenon.
The separation of seed and fertilizer is not good: the germ of seed germinates out of the radicle and emerges germ and comes into contact with the fertilizer, destroying the embryonic tissue and causing rot.
It is related to temperature, moisture, and oxygen: when the soil moisture is 70%, the seedling emergence is quick and the seedling emergence rate is high. When the soil moisture is more than 80%, due to excessive soil moisture and insufficient air, it is also easy to rotten species, affecting the emergence rate.
Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
