How does jujube seedling wilt do?
Recently, many farmers reported that some jujube seedlings planted this spring gradually wilted when the new shoots grew to 10-20 centimeters, until they withered. Our analysis shows that: 1. From the point of view of climatic conditions, it is related to this year's special climate, such as low temperature, sandstorms and so on. In mid-April after jujube seedlings were planted, the low temperature in our city lasted for about a week, and the lowest temperature was below 10 degrees. The soil temperature is low and the root activity is bad. At the same time, the frequent sandstorms that occurred this spring also caused the transpiration of newly planted jujube seedlings to be too large, resulting in wilting of the seedlings due to loss of wood and water.
