How to cut poplars, what fertilizer to apply to cuttings of poplar seedlings

It is very easy to do, the skill is inserted into that job, and there is a way to "plant flowers without blooming, and unintentionally plant willows and willows".

First, the selection of nursery land and land preparation.

The nursery land should be fertile, moist and well-drained soil, which is not suitable for arid and barren land with stagnant moisture. The nursery must be located in a convenient place for irrigation to ensure that it can be irrigated at any time. Before cuttings, the nursery must be leveled and fine, so as to avoid drought at high places and water accumulation at low places during irrigation, resulting in uneven seedling emergence rate.

Second, the false planting of seed strips.

The quality of seed strips is an important internal factor affecting the survival rate, and annual seedlings should be used for dry seed strips in cuttings, and the seed strips should grow robustly, without diseases and pests, and have a good degree of lignification. When harvesting in winter, the seed strips should be planted in the false planting ditch, which is 100 cm deep and 60 cm wide. When the seedlings are raised in the spring of the second year, cut the cuttings before digging out.

3. Cuttings are cut.

The length of the cuttings is about 15 cm, and there should be a bud 1 cm from the top.

Fourth, the treatment of cuttings.

When soaking, you can dig a 1-meter-deep soil pit next to the irrigation, soak the cuttings after filling with water, and release the water after the water seeps. The soaking of cuttings in water can not only make them absorb enough water, but also dissolve the rooting inhibitors in the cuttings, which has a significant effect on improving the survival rate of cuttings. It is particularly important to soak the strips brought in from other places.

The immersion time should be 24 hours.

Fifth, the time of cuttings.

Cuttings can be made in the spring as soon as the soil thaws. Timely and early insertion is beneficial to improve the survival rate.

Sixth, the cutting method.

The cuttings are inserted directly into the seedbed. Do not turn the cuttings upside down when cuttings. When cuttings, cuttings should be made according to the cuttings at the base of the seed strip, the middle and the top cuttings respectively.

In this way, the seedlings can grow neatly and avoid the phenomenon of bullying the small. Cuttings must be irrigated immediately to make the cuttings tightly bound to the soil, so that the cuttings have sufficient water absorption.

7. Cutting density.

The density of poplar cuttings is generally about 4000 plants per mu, and the row spacing of the plants is determined according to the nursery cultivation method. If you want to grow two-year-old seedlings, the cutting density can be changed by yourself.

8. Parenting management.

1. Irrigation. After the poplar cuttings sprout, they initially rely on the nutrients contained in the cuttings themselves and the water absorbed from the soil by the lower incisions to sustain life and growth. After entering the rooting period, young leaves grow at the top of the seedlings, and the seedlings begin to grow in earnest.

The seedling rooting period lasts until mid-May. During this period, the temperature is constantly rising. The water consumption of seedlings gradually increases, and once the water is insufficient, the water dynamics of the seedlings is unbalanced, and wilting will occur until death.

Therefore, the key to management during this period of time is to ensure moisture**.

2. Wipe the buds. After the seedlings grow, they grow side branches, and they need to be wiped. When the side branches are very tender, they should be removed directly by hand, and if they have been lignified, they need to be pruned.

The first bud wiping should be delayed, generally at a height of 40 cm, so that the root system of the seedling can get the nutrients provided by the photosynthesis of the early lateral branches, so that it can grow and develop normally.

3. Top dressing. Nursery topdressing generally uses about 50 kg of urea per mu a year, and a certain amount of phosphate fertilizer and potassium fertilizer can be added according to soil conditions. Top dressing is generally carried out in three phases in late May, mid-June and mid-July.

4. Pest control.

In the development of poplar cultivation. It is necessary to attach importance to the prevention and control of diseases, and comprehensively implement the policy of "prevention first, comprehensive treatment" based on cultivation technology.

Summary. Pro, cuttings poplar seedlings apply urea, and at the same time, a certain amount of phosphate fertilizer and potassium fertilizer can be added according to soil conditions.

Pro, cuttings poplar seedlings apply urea, and at the same time, a certain amount of phosphate fertilizer and potassium fertilizer can be added according to soil conditions.

Top dressing is generally carried out in three phases in late May, mid-June and mid-July.

Before cuttings, the land must be fully prepared, requiring a depth of more than 25 cm, and the rent is deep and fine. If the source fruit is a rotary tiller, it is best to collapse after ploughing. During deep ploughing, fertilizer is applied according to 20 kg of urea, 75 kg of superphosphate, 10 kg of potassium sulfate and other fertilizers per mu as base fertilizer, and 1-2 kg of carbofuran per mu is applied to kill the old pests.

The above is all my reply, I hope to help your relatives, I wish you a happy life.

Summary. Hello! Cuttings of poplars can be soaked with carbendazim with rooting powder. The advantage is that it can not only sterilize but also promote the rooting of branches.

Hello! Cuttings of poplars can be soaked with carbendazim with rooting powder. The advantage is that it can not only sterilize but also promote the rooting of branches.

After diagonal cutting, it is treated with rooting powder. Method: 1. Quick dipping method.

The shoots were soaked in ABT rooting Changhengbi powder with a content of 500 200 mg kg solution for 30 seconds before cuttings. In seedlings, this method is used only for single bud cuttings or repeated treatments. 2. Immersion method.

The content of cuttings treated with ABT rooting powder was inversely proportional to the soaking time, that is, the higher the auxin content, the shorter the soaking time. The lower the content, the longer the soaking time. In addition, the ratio of its content varies according to the plant species and the maturity of the branches, usually the concentration of flowers and broad-leaved trees is lower, the conifer tolerance is higher, the treatment content of young branches is lower than that of completely lignified branches, the content of treated seeds and seedling roots is lower than that of treated branches, and the concentration of hard-to-root trees is greater than that of easy-to-root tree species. When treating shoots, the concentration of soaking generally ranges from 50 200 (mg kg).

The soaking method is to prepare ABT rooting powder into a solution of 50 mg kg or 100 mg kg or 200 mg kg as needed, and then soak the lower part of the cuttings in the solution for 2 12 hours. This treatment is particularly important for dormant branches, as it ensures that all the liquid absorbed by the cuttings is used for the formation of adventitious roots.

1. Cuttings: Poplars are best cut in early spring, when the climate begins to rise. 2. Cuttings:

Cut the bottom of the poplar sapling at an angle of 45° and dip it in rooting powder. 3. Cuttings: First dig a hole in the soil, and then insert the poplar seedlings into the soil.

4. Watering: Water enough water to the roots of poplar seedlings to keep the soil moist.

1. Cutting time

Poplar seedlings are generally cut in spring from February to March, the climate has just picked up in February, the moisture content in the air gradually increases, and the poplar seedlings can survive quickly after cuttings, and will not be irradiated by strong light, which is conducive to the better growth of poplar seedlings in the later stage.

2. Handle cuttings

Before cutting poplar seedlings, first choose a section of strong branches with a length of about 15 cm as cuttings, cut the bottom of the branches into a horseshoe shape with scissors, and then soak the poplar seedlings in rooting water to promote the germination of new root systems.

3. Cutting method

When cutting poplar seedlings, first use a shovel to dig a small hole in the soil, then insert the seedlings into the soil, and press the soil at the root system with your hands, pay attention to control the strength to prevent the root system of poplar seedlings from breaking.

4. Replenish water

After the poplar seedlings are cuttings, they should be poured into the soil once with a kettle to provide sufficient nutrients for the plants and promote the growth of stems and leaves, and when the poplar seedlings are maintained in the later stage, they can be watered every 5-6 days to keep the soil moist.

1. Selection of seedling land: The seedling land should be selected in the fertile, moist and well-drained plot, and the same as the hand must ensure that the plot has the characteristics of convenient drainage and irrigation, so as to ensure that it can be irrigated and drained at any time.

2. Land preparation and fertilization: Before cuttings, the land must be fully prepared, requiring a depth of more than 25 cm, so as to achieve deep ploughing and fine finishing. If it is a rotary tiller, it is best to collapse after ploughing.

During deep ploughing, fertilizer is applied according to 20 kg of urea, 75 kg of superphosphate, 10 kg of potassium sulfate and other fertilizers per mu as base fertilizer, and 1-2 kg of carbofuran per mu is applied to kill underground pests.

3. Seed strip collection and treatment: poplar cuttings and seedlings should be collected with good lignification, no disease and insect damage, straight and perfect dry shape, and 1-year-old rice tall seedlings with full side buds are known as cuttings, which are generally the best quality in the middle and lower parts. The picking time is generally in the spring before germination with the cutting, but can also be in late autumn, after the seedlings fall leaves, the winter storage can promote the incision to form callus, is conducive to the rooting of cuttings.

4. Cutting time and method: In general, it is appropriate to take cuttings in early spring. The cuttings are inserted directly into the seedbed, and the cuttings should not be turned upside down when cuttings.

In addition, cuttings are made according to the basal cuttings, middle and top cuttings of the seed strips. In this way, the seedlings can grow neatly and avoid the phenomenon of bullying the small. Cuttings must be watered immediately after so that the cuttings are tightly bound to the soil.

5. Timely topdressing: topdressing generally uses about 50 kg of urea per mu a year, and a certain amount of phosphate fertilizer and potassium fertilizer can be added according to soil conditions. Top dressing is generally carried out in three phases in late May, mid-June and mid-July.
