What is the best season to plant Nanmu seedlings? Why?

In spring, late January to mid-February is best. Because the survival rate of seedlings planted before and after the rain solar term is the highest.

It is best to plant in the spring, because the temperature is suitable at this time, which is very suitable for the growth of Nanmu trees. After planting, nitrogen and potassium fertilizers should be supplemented regularly to promote the growth of plant rhizomes. Water in moderation and keep the soil moist.

I think it's best to plant in the spring, because it's warmer and the seedlings won't freeze to death.

What is the best season to plant Nanmu seedlings? Why?

The above nonsense is a big article, I talk nonsense, no matter what kind of tree, it is generally the rainy season, or the season when the climate is shady, as the old saying goes, August 15 can also be planted with a wooden stick, and the winter is also very good, the winter plant slippery and quietly search for things to begin to hibernate and the leaves fall, and begin to preserve nutrients, at this time only the roots of the letter calendar, the source of spring begins to sprout Except for tropical plants, because those plants prefer sunlight. Hope it helps.

The planting method of Nanmu is as follows:

1. Sowing: Nanmu, propagated with seeds, after the fruit is harvested, rub off the exocarp, the seeds are oily, the life is short, and it can be sown after drying. Seedlings grow slowly in the early stage, like shade and humidity, and it is advisable to choose a fertile and moist soil with short sunshine time, convenient drainage and irrigation, and as a nursery.

The soil is heavy and clayy, with poor drainage, and is prone to root rot; If the soil is dry and lacks water, the seedlings will grow poorly and will easily cause burns. Sowing can be carried out from "cold" to "rain". Before sowing, the nursery should be fully fertilized, and the soil preparation and bed should be meticulous.

Generally, strip sowing strips are used, with a strip spacing of 15-20 cm and a strip width of 6-10 cm.

2. Seedling treatment: When the seedlings are about 10 cm high in July, the seedlings can be fixed. 30,000 seedlings per mu.

August to October is the fast-growing period of Phoebe nanmu seedlings, during which the water and fertilizer management of the nursery should be strengthened to accelerate the growth of seedlings and improve the quality of seedlings. In November, some plants still grow in the shoots, so in the later management of the nursery, it is necessary to pay attention to avoid frost damage to the seedlings during wintering. The afforestation effect of 1-year-old seedlings is better than that of 2-year-old seedlings.

Some seedlings with weak growth can be left in the nursery for a year to be reforested.

3. Afforestation: Nanmu likes moisture and is shade-tolerant, and the site conditions are high, so it is advisable to choose alluvial land with deep soil layer and fertile slopes and valleys. Poor afforestation conditions are not easy to form forests.

Land preparation requires meticulousness, the general woodland is used to deep plough the land with a belt, and the fertile woodland can be prepared in the form of a hole, with a hole diameter of 50 cm and a depth of more than 30 cm. Spring and autumn afforestation can be selected for afforestation season, but early planting is better than late planting. Before planting seedlings and afforestation, it is necessary to properly prune some branches and leaves and excessively long roots.

4. The main insect pest control of Nanmu chinensis: the main pest is the gray hairy goldenrod insect: the adult worm eats the young leaves, young shoots and leaflet cortex, and the young shoots can wither in serious cases. More than 80% of the plants were killed. The maximum number of infested plants was more than 50 insects.

Control method: In late April, the adult insects were fumigated with 621 smoke, and the medicine was kilogram per mu.

Nanmu seedlings grow slowly in the early stage, like shade and dampness, and should choose short sunshine time, convenient drainage and irrigation, fertile and moist soil as a nurseryThe soil is heavy and clayy, with poor drainage, and is prone to root rot; If the soil is dry and lacks water, the seedlings will grow poorly and will easily cause burns. Sowing from the "big cold" and "rain" can be carried out

Before sowing, the nursery should be fully fertilized, and the soil preparation and bed should be meticulous. Generally, strip sowing strips are used, with a strip spacing of 15-20 cm and a strip width of 6-10 cm. The sowing amount per mu is 15-20 kg

After sowing, cover the fire soil 1-2 cm, and then cover the grass or saw, chaff, to keep the seedbed moist

After the seedlings are unearthed, weeding, soil loosening, fertilization and irrigation should be carried out in timeSeedlings in flat land, due to the long sunshine time, high surface temperature, in the summer, easy to be harmed by sunburn, so it is still necessary to give proper shadeHowever, according to the experiment of Fujian Sanming Xinkou Forest Farm, choose the shade of the nursery, appropriately increase the density of seedlings, so that the bed surface maintains a certain coverage, and the seedlings can be avoided without shading

The seedlings should be carried out in stages, and the amount should be less and more often

When the seedlings are up to about 10 cm in July, the seedlings can be fixed30,000 seedlings per mu. August to October is the fast-growing period of Phoebe nanmu seedlings, during which the water and fertilizer management of the nursery should be strengthened to accelerate the growth of seedlings and improve the quality of seedlings.

In November, some plants still grow in the shoots, so in the later management of the nursery, it is necessary to pay attention to avoid frost damage to the seedlings during wintering. The afforestation effect of 1-year-old seedlings is better than that of 2-year-old seedlings. Some seedlings with weak growth can be left in the nursery for a year to be reforested.

Due to the slow growth in the early stage, it is easy to be covered by weeds and affect its survival and growth, so it is necessary to strengthen the tending managementWithin 3-5 years after afforestation, tending should be done twice a year, and the number of tending should be appropriately increased in the lower part of the slope and the weedy area of the valleyThe tending time should be arranged before the arrival of the peak growth season, that is, the first tending is in April to May, and the second tending is in July and August

The crown of Nanmu is slower to develop, and the young are more shade-tolerant, so it is strictly forbidden to beat the branches of the young forest, and the bark must not be damaged when tending, otherwise its growth will be significantly weakened

When the canopy of the forest is completely closed, the understory weeds are eliminated, and there are more pressed trees, tending thinning should be carried outA weak lower layer tending method is used, i.e., cutting down the obvious pressed wood, the double wood and the competing wood around the good woodThinning intensity, should depend on the specific situation, the general forest land is more fertile, the initial planting density is larger (such as 222 plants per mu), the number of trees can be cut down about 30%.

The planting of Nanmu is actually not difficult, the key is to master the scientific method, only the correct planting method can get twice the result with half the effort, reduce the cost of planting, increase the income, and I will introduce to you some problems that should be paid attention to in the process of planting Nanmu.

First, the selection of woodland.

In the woodland in the hilly area, shady slopes or rotten semi-shady slopes should be chosen. The soil layer is deep, and the soil on both sides of the slope or depression is moist and fertile.

2. Land preparation and basal fertilizer application.

Land preparation, subdivision, and cave reclamation. Use a 60 cm x 60 cm x 50 cm pit. The excavated topsoil is spread on the slope opposite the planting hole, and the core soil is placed outside the hole, so that the planting soil is fully weathered and matured after a period of sunshine, and then the bottom fertilizer is applied to improve the physical and chemical properties of the plant.

Soil and re-soil. It must be noted that when the hole is 1 2 to 2 3 deep, the fertilizer should be well mixed with the soil, and then the soil should be filled into the hole so as not to damage the fertilizer.

The amount of basal fertilizer per plant: 100 grams of decaying organic fertilizer, 100 grams of urea, 100 grams of calcium, magnesium and phosphorus, 100 grams of potassium chloride are mixed with backfill and evenly applied to the bottom of the hole. After that, 1-year-old seedlings are planted on the backfill.

It should be noted that the seedlings should be planted deeply, and the bottom of the diameter of the seedlings should not be exposed to the soil. After transplanting, the soil pile is backfilled at the base of the plant, and the soil pile is slightly higher than the hole surface to prevent water accumulation caused by hypoxia.

3. Planting. Planting is a critical process that requires the right timing and method. February-March is the most suitable month for afforestation, but no later than April.

The afforestation density is generally 2 m 4 m or less. It is best to plant after the spring rains. Especially when planting bare roots, prune the seedlings before planting the roots into the hills.

When transplanting, pay attention to straightening the seedlings and burying them properly, generally 2 3 cm higher than the original rhizome, and then compacting the seedlings. When planting bare-root trees, prune two-thirds of the seedlings and leaves as soon as possible, mainly around spring.

Fourth, create mixed forests.

Mixed crossing or branching could improve the survival rate of Phoebe chinensis, but the growth of seedlings was slow. Therefore, the mixing ratio should be controlled and the relevant tree species should be cut down in time. The mixture of nanmu and fir wood is good.

Generally, fir trees account for about 20%. As an associated tree, it is more conducive to cultivation. It can also be used with sycamore, sycamore, camphor, sassafrass tree,.

The mixing ratio is 1 and 3 1, preferably 2 1.

The best way is to buy directly, or choose the right varieties to be transplanted, so that many problems can be solved, it can be more convenient, you must choose the right land for planting, pay attention to watering with ants, pay attention to the drainage of the soil.

To choose the right soil, we should pay attention to the appropriate density of the reed, and we should also pay attention to the appropriate distance, and we must put it in a place with better sunlight and better ventilation, and we should water and fertilize it in time. Stool training.

It can be planted in the soil, it can be planted in water, it can be planted in a semi-shady slope, and it can be planted after planting this kind of tree with some water and some fertilizer.

1. Choose a fertile and moist soil with short sunshine time, convenient drainage and irrigation, and as a nursery;

2. Before sowing, the nursery should be applied with sufficient base fertilizer, and the land preparation and bed should be meticulous;

3. Sowing can be carried out from "big cold" to "rain brother file water", generally the number of dust is sown in strips, and covered with fine yellow soil 1 to 2 cm after sowing;

4. After the seedlings are unearthed, weeding, loosening the soil, fertilization and irrigation should be carried out in time;

5. According to the experiment of Fujian Sanming Xinkou Forest Farm, the shade nursery land was selected, and the seedling density was appropriately increased, so that the bed surface could maintain a certain coverage, and the seedling burn could be avoided without shading; The seedlings should be carried out in stages, and the amount should be less and more often

6. When the seedlings are as high as about 10 cm, the seedlings can be fixed, and 30,000 seedlings are left per mu; August to October is the fast-growing period of Phoebe chinensis seedlings, during this period, the water and fertilizer management of the nursery should be strengthened to accelerate the growth of seedlings.
