How long does it take for the saplings to be planted to know whether they are alive or not and how long can they be fertilized?

It takes about 30 days to know whether the seedlings have survived. Judgment method: After the seedlings are planted, if the leaves turn green, the water is full and the xylem is brightly colored, it means that the seedlings basically survive. If you want to further confirm, you can dig a small hole in the soil ball near the root system of the seedling for observation. If a new white root grows on the root, it means that the seedling really survived.

First, how long will it take to know whether the saplings are alive or not?

1, time

It takes about 30 days to know whether the seedlings have survived.

2. Judgment method

(1) General judgment method: In general, after the seedlings are planted, if the leaves turn green, the water is full and the xylem is bright, it means that the seedlings have basically survived.

(2) Further judgment: Dig a small hole near the soil ball of the seedling root system for observation. If the roots grow new white roots, it means that the roots have begun to grow and develop, and the absorption capacity has been restored, which means that the seedlings have really survived.

(3) It should be noted that after transplanting, some saplings will consume the nutrients of the mother and grow new leaves, but their roots have not survived.

3. Methods to improve the survival rate of transplanting

(1) Determine the specific transplanting point according to the characteristics of transplanted plant varieties, and provide a suitable growth environment.

(2) Select healthy and disease-free saplings for transplantation.

(3) The seedlings should be pruned properly before transplanting, which can improve the water use efficiency and the survival rate of seedlings.

(4) After transplanting, water in time and root liquid at the same time to promote the rapid recovery and growth of plant roots.

Second, how long does it take to fertilize the seedlings after sowing?

1, fertilization time

Generally, before planting seedlings, an appropriate amount of fertilizer is applied as base fertilizer. If base fertilizer is not applied, it should be applied after the seedlings survive (usually in May-June). It should be noted that fertilization is not suitable until the injured roots of newly planted trees are completely healed.

2. Matters needing attention in fertilization

(1) If it is organic fertilizer, it must be fully decomposed before application; If it is caked fertilizer, it must be crushed before application.

(2) After fertilizer application, water it in time.

(3) Fertilization amount should be adjusted according to varieties, tree age, growth, land fertility and other factors.
