High grafting technology of jujube
Due to the variation of long-term cultivated varieties, the quality of jujube trees planted in different places varies greatly at present. As far as Jinsi jujube is concerned, there are dozens of phenotypes in Jinghai, Tianjin, and there are great differences in fruit size and shape. The appearance of the harvested jujube products is poor. As a result, the price of its commodities has been greatly reduced and the economic income of farmers has been reduced.
In order to solve this problem effectively and make the fruit of the same jujube orchard neat and consistent in appearance, the method of high grafting is often used in production at present, and the jujube trees with great differences in quality are grafted into two jujube varieties with better quality.

Key points of soil Management in Pear Orchard
Pear trees have strong resistance and wide adaptability, and can be cultivated in sandy land, mountainous area and hilly land. The planting soil should be more fertile sandy loam with deep soil layer and good drainage. 1. Deep ploughing of pear orchard soil can deepen the root distribution layer, make the root system develop to the depths of the soil, reduce the "floating root", improve the ability of drought resistance and absorption, and have a significant effect on rejuvenating the tree potential and improving the yield and quality. The interlaced deep turning method is often used in production, all of which have been used for 2 to 3 years, and annular trench can be used to expand the hole. Deep turning time, it is better to finish before the leaves fall in autumn.
