Prevention and Control Methods for Bark Cracking and Trunk Dehydration in Young Jujube Trees
Yining County once developed jujube trees on a large scale. In years with heavy winter snowfall, when the snow melted in early spring, the trunk below the snow line (about 20 cm high) was soaked by melting snow water and exposed to wind, causing rot and bark splitting, which blocked the tree's vascular tissue and led to drying and death.

Detailed Explanation of the Method for Raising Jujube Seedlings by Root Cutting and Returning to the Nursery
To raise jujube seedlings by root cutting and returning them to the nursery, first select plants of excellent quality and free from pests and diseases as mother plants. Before budbreak, dig a trench 30-40 cm wide and 40-50 cm deep around the outer edge of the mother plant's canopy to cut the jujube roots, and use scissors to trim the cut root wounds smooth. Apply decomposed organic fertilizer, about 75 kg per plant, mix it with moist soil, fill it into the trench and tread it firm. If conditions permit, it is best to irrigate thoroughly once. Then cover with a layer of loose soil to conserve moisture. After the jujube roots are stimulated, a large number of clustered root-sucker seedlings will appear on the ground near the trench in May-June. Management of the root-sucker seedlings should be strengthened in a timely manner. After budbreak, remove excess buds; the principle is to remove the dense and keep the sparse, and remove the weak and keep the strong, generally with a plant spacing of about 15 cm, so as to ensure normal growth of the seedlings.

Pear Tree Spring Pest Control Methods and Technical Key Points
Pear tree spring pests and diseases include: pear fruit borer, aphids, red spider mites, pear psylla, stink bugs, leaf-mining mites and black spot disease, etc. Timing and measures of control: from early spring to before flower buds swell, clean the orchard and scrape tree bark. Lay plastic sheeting under the tree, then scrape off the raised and coarse bark on the trunk and large branches, but do not damage the new bark. For the coarse vertical bark at the branch forks, scrape carefully. Collect the scraped bark, larvae, eggs, etc. and bury them deep or burn them. Knock down dead leaves and remaining dried fruit from the tree and remove them from the orchard for destruction, then spray the whole tree once with lime sulfur mixture.

Management Methods for Pear Trees in the Late Full-Bearing Stage and the Senescent Stage
Once pear trees enter the late full-bearing stage and the senescent stage, poor management, insufficient fertilizer and water, excessive fruiting load, and worsening pests and diseases will accelerate the trees' decline and death, causing them to lose their cultivation value. I. Manifestations of pear trees in the late full-bearing stage and the senescent stage. Late full-bearing stage: yield declines year by year,
