Planting rootstock seedlings of du pear in rainy season
Du pear is an excellent rootstock of grafted pear varieties, which is resistant to drought, cold and barren. It is generally planted in spring and autumn, but in remote and water-deficient mountainous areas, the survival rate is often affected by difficulties in transporting water and drought in spring. The fruit growers in our region have the experience of planting du pear rootstock seedlings in the rainy season, which has the advantages of high survival rate, fast establishment and low cost.
1 after the arrival of the continuous rainy season, when the underground water content is close to saturation, it is best to plant in the rain or before the rain.
(2) to dig the tillering seedlings of du pear nearby from the hillside, it is suitable for the seedlings to be thick and 0.8~2.0cm, which requires the integrity of the root system and bring soil as far as possible.
(3) after planting, the tree plate was covered with grass to moisturize, and cut off part of the new shoots to reduce water transpiration.
Four kinds of rootstocks that sent out new shoots in the early year will be grafted when the rootstocks leave the bark in mid-late August, and those planted late without new shoots can be grafted in the following spring.

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.
