How to raise the seedlings of the camphor tree, and when the seedlings of the camphor are raised

Camphor. It is an evergreen tree species that is usually cultivated and managed in spring and autumn. However, the best time to raise seedlings should be in the spring.

Spring is the beginning of the seedling growth period, the weather gradually warms up, and the soil begins to thaw, which creates a good environment for the seedlings to grow. At this time, the seedlings begin to sprout and flower, and at normal temperatures, the seedlings grow very quickly. Therefore, at the right time in spring, it is very critical for the cultivation of camphor seedlings.

If we buy camphor seedlings in the spring, we need to pay attention to the following points. First of all, you need to choose good quality and high-quality seedlings, after determining the variety of seedlings to buy, it is best to find a regular nursery to buy. Secondly, it is necessary to pay attention to the irrigation and fertilization of seedlings to ensure that the roots of seedlings receive sufficient water and nutrients to grow healthily.

In addition, because the temperature is relatively stable in spring, it will not encounter high temperature in summer or cold in winter, which will not have much impact on the growth of seedlings.

In short, spring is the best time for camphor seedling cultivation, as long as you pay attention to the cultivation and management of seedlings, you can make the seedlings grow and develop well in this season.

Seedling raising technology of camphor tree:1

Nursery plot selection.

The nursery should be selected with a deep and fertile soil layer. Well drained light, medium loam. 2. Fertilization of land preparation.

If the soil moisture is poor, it should be watered first to create moisture (so that the soil moisture content reaches 60-70%). Apply 2-3 square meters of fully fermented and decomposed pig manure (more than 20 days) as base fertilizer per mu to increase soil microorganisms, improve soil and improve soil fertility. Deep ploughing (20-25 cm) with a fine rake, picking up the root stubble.

Strive to sow all seedlings at once.

Seed treatment. Seeds with warm water of about 30 degrees.

Intermittent soaking and germination for 5-7 hours, and sowing can be done after the seed coat moisture is dried.

Sow. Sowing is done from early February to early March (ditching strips). The row spacing is 30 cm, and the sowing depth is about 2 cm. (After sowing, the mulch film can emerge 5-7 days in advance). About 25 kg of seeds are needed per mu. 5

Seedling management. It can germinate and emerge in about 25 days after sowing. The plant height is 5 cm time seedlings, fixed seedlings (plant spacing is about 7 cm), go to weak and diseased seedlings, and leave strong seedlings.

After the seedlings, and June, July and August to see the seedlings to see the day top dressing watering (19-6-20 compound fertilizer, 15-20 kg mu each time).When the camphor wasp was found, it was sprayed with 2000 times of malathion aqueous solution to control the whole field. ··

Camphor tree is the best living tree, can be planted all year round, especially in the spring 3-5 months planting is the best live, (artificial and growth cycle) first of all, the first one is the first time to give water must be enough, with a wooden stick to beat the mud, so that the seedling position is fixed, the roots do not enter the air, and then cover the soil (the soil must be 5-10 cm higher than the roots), after 5-10 days to replenish water. Around 25, the leaves will appear.

1, sowing timeSpring sowing from early February to early March, can also be sown in winter. Strip sowing is adopted, the strip spacing is 30 cm, and the sowing amount per mu is 25 catties. The seeds that have been stored in wet storage should be germinated before sowing, and the seeds should be soaked intermittently with warm water to promote germination, and the seeds should not be soaked at high temperature to prevent scalding the seeds.

2. Places that need to be paid attention to when sowingIt is necessary to ensure that the camphor tree can absorb nutrients, so that the camphor tree will survive and its value will be higher, so it must ensure that the sun is sufficient.

First, the introduction of the camphor tree material dense, fragrant, is the best building, furniture, craft of good materials, camphor and camphor oil are widely used in technology, OEM, medicine and national defense industry, in addition to the camphor tree is also the "four sides" greening of the excellent tree species. Camphor tree is an evergreen tree, light-loving, strong taproot, developed root system, warm and humid climate, strong adaptability, fast growth, long life, in the deep soil, fertile flat on all sides, river beach alluvial growth is the best. 2. Seedling 1 time.

From October to December every year, the mature seeds are picked, then mixed with sand and stored, and can be germinated and sown in early March. 2 Land preparation. Carry out the first tillage harrow at the beginning of winter, carry out the second tillage before sowing, and apply sufficient base fertilizer, the base fertilizer is generally used with rotting manure, 1500 2000 kg per mu or 50 kg of carbon amine, 50 kg of phosphate fertilizer, 150 kg of vegetable cake, and then build a high bed, generally 35 50 cm high, bed width meters.

3 Germination. At the beginning of March, camphor trees need to be germinated before sowing, and can be soaked in 50 warm water, and when the warm water cools down, then change to 50 water and repeat soaking 3 4 times, which can make the seeds germinate early for 10 15 days. 4 Sowing.

The spacing between the row of the sowing is about 20 cm, the sowing amount per mu is 10 15 kg, and the soil is covered with straw or plastic film after sowing, so as to keep the topsoil of the seedbed moist to facilitate seed germination. 5 Parenting management. After the seedlings are unearthed, the straw or mulch film should be removed in time, and the seedlings can start to be seedlings when they grow a few true leaves, and the seedlings can be set about 10 cm high.

There are about 20,000 camphor seedlings per mu. After July, fertilizer and water management should be strengthened, and the soil should be loosened and weeded frequently. At the end of autumn, top dressing and irrigation should be stopped.

Top dressing is generally 2 3 times, the first two times can be used urea 7 10 kg, the last time can be used 10 kg of urea, phosphate fertilizer kg. The 1-year-old seedlings of camphor trees can reach more than 50 centimeters, and the ground diameter can reach more than centimeters.

3. The transplanting time is more suitable from mid to late March to early to mid April, and the transplanting density is about 1500 plants per mu. With the move, after transplanting about 10 cm from the ground cut rod, when the bud grows to about 10 cm can be set the main rod, cut off the excess branch buds, leaving a relatively thick branch. In winter, 2000 kg of manure is applied to the bed.

In this way, the DBH of 3-year-old seedlings can reach more than 3 cm.

Before the camphor tree seed seedlings need to choose a suitable nursery, the terrain is flat and fertile sandy soil can promote the growth of camphor trees, and then the ferrous sulfate and calcium phosphate are mixed and sprinkled in the soil, and the width of the furrow is controlled within the length of the meter, the height is within 25 cm, and finally the sowing can be dispersed.

1. Nursery selection

How to raise camphor tree seeds is the first to choose a nursery, the planting area should be selected close to the afforestation land of the first side, so that the traffic is more convenient, at the same time the terrain is relatively flat, sufficient water source a deep soil layer, soil preparation needs to be fertile and the ability to loosen the number of sandy soil is relatively strong.

2 Land preparation.

In the camphor tree seeds sowing 7 days before the land preparation has been carried out, each mu needs to add 3 kg of ferrous sulfate and 200 kg of superphosphate, fully mixed evenly sprinkled on the soil, to add some fertility to the soil, according to the nursery to make furrow length, furrow width can be kept in meters, furrow height needs to be controlled within 25 cm, the distance between furrows needs to be 35 cm above, and the lower part is within 22 cm.

3. Seed treatment

After the completion of the land preparation, it is necessary to carry out seed treatment, the seeds of the camphor tree are soaked in potassium permanganate solution for 2 hours, and then placed in 50 warm water to promote germination treatment, the soaking time can be within 2 hours, and then it can be placed in cold water for 24 hours to remove inferior seeds, and so on about 50% of the friends can be sown.

4. Sowing process

The seeds of the camphor tree are relatively small, can be used to spread and strip sowing, after sowing need to cover about 1 cm of soil, if the temperature is not suitable, it needs to be covered with 2 cm thickness of straw, during the emergence of the need to maintain the humidity and temperature of the soil, to promote the rapid germination of camphor seeds.

Before the camphor tree seed seedlings need to choose a suitable nursery, the terrain is flat and fertile sandy soil can promote the growth of camphor trees, and then the ferrous sulfate and calcium phosphate are mixed and sprinkled in the soil, and the width of the furrow is controlled within the length of the meter, the height is within 25 cm, and finally the sowing can be dispersed.

How to raise camphor tree seeds is the first choice of nursery, planting area should be close to the place close to the afforestation land, so that the traffic is more convenient, at the same time the terrain is relatively flat, sufficient water source a deep soil layer, soil preparation needs to be fertile and loose ability of the sandy soil.

2 Land preparation.

In the camphor tree seeds sowing 7 days before the land preparation has been carried out, each mu needs to add 3 kg of ferrous sulfate and 200 kg of superphosphate, fully mixed and evenly sprinkled on the soil, for the soil to supplement the number of some fertility, according to the nursery to make the furrow length, the width of the furrow can be kept in meters, the height of the furrow needs to be controlled within 25 cm, the distance between the furrow needs to be 35 cm above, and the lower part is within 22 cm.

3. Seed treatment

After the land preparation is completed, the seed treatment needs to be carried out, the seeds of the camphor tree are soaked in potassium permanganate solution for 2 hours, and then placed in 50 warm water to promote germination treatment, the soaking time can be within 2 hours, and then it can be placed in cold water to soak 24 small resistant time to remove inferior seeds, and so on about 50% can be sown.

4. Sowing process

The seeds of the camphor tree are relatively small, can be used to spread and strip sowing, after sowing need to cover about 1 cm of soil, if the temperature is not suitable, it needs to be covered with 2 cm thickness of straw, during the emergence of the need to maintain the humidity and temperature of the soil, to promote the rapid germination of camphor seeds.

The fruits of the camphor tree can be used to raise seedlings, and when the berries are purple-black in mid-November, a robust mother tree that has been free of diseases and pests for about 40 years is selected.

Before sowing (early March), soak the seeds in warm soup (50), replace them after cooling, repeat 3 4 times, and the seeds can germinate 10 to 15 days in advance. The seeds can also be mixed evenly with river sand, wrapped in film and exposed, and kept moist until a small number of seeds germinate, after 7 days, the seed shell begins to crack, the seed embryo is slightly protruding, and it can be used for sowing at this time.

After the seedlings are unearthed, remove the straw or mulch, and the seedlings can be separated when there are several true leaves, and the seedlings are about 10cm high, and the number of seedlings is about 300,000 hm2. After July, it is necessary to strengthen the management of fertilizer and water, and often loosen the soil and sell the grass. At the end of autumn, top dressing and irrigation should be stopped.
