After the fruit tree seedlings are planted, they should be dried immediately. When they are dried, they should be cut at a place more than one inch (4 cm) away from the first bud, and then the cut should be sealed with paint to prevent air drying. The seedling height of different tree species is not enough, and one can grow differently. For example, pear trees are about 50 cm long and jujube trees are shorter.

Excellent varieties of seedlings should be purebred and adapt to local natural environmental conditions. The height of excellent fruit trees should be 1 ~ 1.3 m, and the ground diameter (above the interface 10 cm) should be 0.8 ~ 1 cm. Grape Miao Di diameter is not less than 0.6 cm.

The roots of excellent fruit tree seedlings should have more lateral roots and fibrous roots, which are evenly distributed. One or two seedlings should have more than three lateral roots, and the roots should not lose water.

Extended data:

The dormancy period of fruit trees is from defoliation in winter to germination in the next year. At this time, almost all fruit tree diseases and insect pests began to hide in the wintering nest, unable to eat or move, and went into hibernation. Therefore, this is the best time to control fruit tree diseases and insect pests once a year. ?

Soft rot, gray mold, downy mildew and other diseases, red spider, borer, caterpillar and other pests. Most of them hide in dead branches, fallen leaves, weeds and garden debris for the winter.

Therefore, after fruit picking or defoliation, the orchard should be cleaned in time, and the branches of diseases and pests, dead branches, insect buds, dead fruits, etc. should be cut off first; Then clean up the fallen leaves and fruits under the tree, and at the same time clean up the sundries around the garden and bury them deeply, destroy them or make compost, so as to basically eliminate the pests or germs that overwinter in these sundries.
