Camphor tree seedling technology, how to breed camphor trees

1. Land preparationFirst germination, soaking in water seedling soil should choose deep soil, fertile, good drainage of water sandy loam soil or light clay soil is preferred. The depth of nursery ploughing is based on the principle of not plowing the subsoil, and it is best to plough once when the soil is dry and humid at the beginning of winter, and rake once when the soil is about to be sown in late winter and early spring, so that the rake is fine and flat. The base fertilizer is better than manure, compost, cake fertilizer and other farm fertilizers, but it should be fully decomposed before application.

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.

Measure the diameter of the tree to select the sapling, and the circumference of 10cm above the ground is equal to the diameter.

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.

1. Nursery selection

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 propagation methods of camphor trees mainly include sowing propagation and cuttings propagation. Sometimes, however, seed propagation can also be used.

Spring planting is suitable from mid to late March to mid-April, autumn planting is suitable for September, followed by the rainy season, which can be used as a good opportunity to fill up.

Planting specifications and precautions:

When the new afforestation of C. camphora is planted in a piece, the row spacing of the planting plants is or, and the size of the planting pit should reach 30cm 30cm 40cm, and the bottom of the hole is fertilized. When planting, fill in the topsoil (bury the soil to the root neck of the seedling), and lift the trunk up after filling, compacting, which is conducive to the stretching of the roots. The root soil should be closely connected with the cave soil, and the soil is not tight and unreal will form a hanging hollow.
