In newly planted fruit trees, it is often found that the seedlings do not wither, but they do not germinate. Even if they germinate, they do not grow for a long time. This is the so-called "stiff seedling". Once a fruit tree has "stiff seedlings", it will not only affect its growth in the year and delay the fruiting period. If it is not handled in time, it will also cause a large number of deaths, which will directly affect the output of fruit.
Measures to prevent "stiff seedlings" of fruit trees
1. Choose a suitable rootstock and soil. When buying seedlings, in addition to choosing good varieties, it should also be noted that the rootstocks of fruit trees should be suitable for the soil conditions in the region.
2. Choose strong seedlings for planting. Choose tree seedlings with well-developed roots, strong stems, full bud eyes, and good rootstock and scion connections for colonization.
3. Choose the best time for colonization. After the soil has thawed to the planting depth, it can be planted. At this time, the temperature is relatively low. After the temperature rises after the seedlings, it is the best time for seedlings to germinate and grow, which can increase the survival rate.
4. Dip the wounded roots with mud before planting. Make deep pits and shallow burials, and shake the saplings while burying the soil to facilitate the extension of the roots, so that the soil and roots are closely connected, and finally the soil is compacted. Keep in mind that watering is done once and the film is covered to protect the moisture. Frequent watering is not suitable.
5. Reasonably set dry. After the fruit tree is planted, cut the trunk. Generally cut at the full buds between 50-120 cm dry (the specific height is determined by the height of the seedlings)
6. "Bagging" planting can be used in dry and windy areas in spring. The plastic bag used is tailored according to the fixed dry height. Use a plastic strip with a width of 5 cm, leaving the mouth open, and align the left, right and upper mouths to iron. The plastic film should not be too thin (such as mulch), because it is not strong and easy to stick to the seedlings, which is not good for it. After the saplings are planted, put the bag on the trunk and bury the lower mouth with a pile of wet soil. As the temperature and humidity of the trunk growing environment are improved, it is conducive to its germination. After sprouting, gradually open the upper mouth, and remove the bag according to the growth situation. Planting with bagging can promote the germination of fruit trees, grow neatly, and eliminate the phenomenon of "stiff seedlings". The effect is particularly good on fruit trees that germinate late, such as jujube and persimmon.
For the fruit tree seedlings that have sprouted but not yet sprouted, you can carefully observe them. If the seedlings are dry with full buds, they can still survive, and they need to be properly watered and covered with soil. If the seedlings are found to dry up gradually from top to bottom, cut off the dry parts and apply disinfectant to the cut mouth to allow new shoots to germinate.
