Soil moisture and drought are important factors in assessing the degree of soil drought. The detection of this item can be used. The soil moisture tester is used for monitoring.墒 refers to the humidity in which the soil is suitable for plant growth and development. Lyricism refers to the condition of soil moisture. Soil moisture is the dryness and wetness of the soil, that is, the actual water content of the soil. The available soil moisture content is expressed as a percentage of the dry soil weight: soil water content = water weight / dry soil weight × 100%. The soil moisture is some evaluation on the definition of soil moisture, and the evaluation between soil moisture and drought is different. The following is a brief introduction: Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.

The soil moisture is divided into five grades, that is, too much, suitable, mildly insufficient, insufficient, and seriously insufficient. The definitions are as follows:
"Excessive" is higher than the relative suitable water content;
“Slightly insufficient†is determined according to the actual production situation, between appropriate and insufficient;
"Insufficient" is less than the relative capillary rupture associated with water content;
“Severe deficiency†is between the deficiency and the relative wilting water content.
The drought evaluation is based on the soil moisture evaluation. According to the drought evaluation index, the drought is divided into four levels: light drought, moderate drought, heavy drought and extreme drought. The evaluation of various parameters is as follows:
Lyric "slightly insufficient" means "light drought";
Lyric "insufficient" means "middle drought";
The grievance "seriously insufficient" means "heavy drought";
Less than the relative wilting water content is "very dry".
