What are the crops suitable for transplanting? Why? Preferably from a cellular physiological or eve

Are you sure it's "transplanting"? Or crops? Are you sure you want to "transplant" those annual herbs of the Solanaceae family of the Poaceae family?

I just think that "transplanting" is mostly used for mature plants, and almost all seedlings of higher plants have extremely active meristems, especially the original meristem, so they can be transplanted as long as conditions permit. Therefore, the transplanting of seedlings, especially the plants with only a few leaves, is more like the advance seedling raising in order to ensure the emergence rate, so the transplanting is universal, and there is no need to talk about whether to transplant or not.

Let's talk about the physiological characteristics of seedlings, because many mature tissues of seedlings are still complete, and the primary and primary meristems account for a large proportion of the plant, so the regeneration ability of the plant is also very strong, especially its root system is not fully developed, and the nutrient channels mainly rely on seeds or other vegetative organs (tubers, roots, cotyledons, etc.), and do not rely very much on photosynthesis, so the survival rate of transplanting is very high, but mature plants may not be.

So transplanting is completely different for mature plants and seedlings.

You are asking about crop transplanting, and the question is really unclear, based on the fact that crops are basically not woody, transplanting is universal to seedlings, I really don't understand what you want to express, please add your question.

Winter wheat, many vegetables such as eggplant, peppers, cucumbers, etc.

Pay attention to the 20 detailed factors that affect the survival of large trees, and the survival rate will definitely be greatly improved.

1. In the process of excavation, hoisting and transportation, attention must be paid to protecting the bark from being damaged, as the saying goes: "people are afraid of sadness, trees are afraid of hurting the bark".

2. After disinfection of the damaged bark, it is necessary to restore the position in time to tie or nail, and if the bark cannot be found in situ, it can be peeled and grafted with the bark of the branch.

3. Pruning is not only related to the size of the tree species and soil ball (root status), but also related to whether advanced technologies such as hanging needle infusion are used.

4. Planting too deep or covering too much soil, resulting in stagnant water or too wet, affecting the respiration of the root system of large trees is an important factor affecting the survival rate of transplanting.

5. It is strictly forbidden to have a sudden fall during the excavation and transplanting process, resulting in "internal injury" or breaking and cracking the trunk and cracking the bark.

6. When digging and transplanting, transplanting rooting powder and resurrection spirit on the root cutting surface and spraying happy forest trees is an important measure to prevent root rot and promote rooting.

7. In the process of excavation, transportation and transplanting, attention should be paid to spraying anti-transpiration inhibitors to minimize water evaporation and improve the survival rate.

8. The combination of root system and soil is not tight during planting, there is no support after planting, and the shaking of the tree and the loosening of the roots are important factors affecting the survival rate.

9. The time from digging to transplantation is too long, and no infusion is carried out to replenish water, resulting in excessive water loss of large trees, which affects survival.

10. For trees and weak trees with great root damage, after transplanting, they should be infusion with hanging needles in time to replenish water and nutrients to promote survival.

11. The mud ball should be kept not loose during transportation, and both sides of the mud ball should be fixed to prevent the soil ball from shaking and scattering the ball, and it should be lifted lightly.

12. For large trees that do not root for a long time but maintain good nutrients, the loosening soil should be strengthened and watered with the rooting solution of the happy forest to promote rooting.

13. Disinfect the planting soil with resurrection to prevent the spread of soil diseases, prevent root rot of large trees, and reduce the survival rate of large trees.

14. When digging when encountering thick roots, they must be shoveled or sawed off with sharp tools, and they cannot be hard to shovel with blunt tools, resulting in root damage.

15. In the summer high temperature world, it is strictly forbidden to contact the tree during transportation, and the air is not circulated, resulting in excessive temperature and burning the tree.

17. The transplanted hole is too small or the bottom of the pot is shaped, and the root system cannot be stretched, resulting in the weak ability of the root system to absorb nutrients, which affects the survival and tree potential.

18. When pruning, pay attention to maintaining the overall crown shape of the tree, remove dead branches, diseased branches, cracked branches, and over-dense branches in the inner chamber, so as to facilitate transplanting and survival.

19. Spring transplanted trees should take antifreeze measures in time in autumn and winter to prevent and control seedling frost damage, and can be sprayed with antifreeze agent in happy forest in combination with physical methods. When the temperature rises after wintering, the plastic film wrapped in the tree for frost protection should be taken out as soon as possible to facilitate breathing.

20. Heavy planting and light maintenance, extensive maintenance, not scientific, affecting the survival rate. As the saying goes: "Three points of seed, seven points of nourishment".

Transplant on a cloudy day or in the morning and evening, cut off a part of the branches and leaves, and cover the plant with shade.

Answer: During the transplantation process, the roots of the plant will be partially damaged, and the root tips will be broken in the soil, which destroys the apical advantage of the root tips, reduces the concentration of kemo branch sensitivity, and promotes the growth of lateral roots.

Answer C Introduction: The root also has an apical advantage, and auxin also undergoes polar transport in the root.
