What is the best solar term for Wei Mao, and what season is the most suitable time for tree planting

The best time to plant trees is after the beginning of spring, especially evergreen trees, and some deciduous trees can also be planted after the leaves have fallen in the fall, but keep warm.

The most unsuitable time is in summer, when the trees are in the peak growing season, and the summer weather is hot, and the evaporation is large, and the root system will be damaged when planting trees, causing the trees to dehydrate and die.

For trees that are not cold-tolerant and hollow in the pith, they should not be planted in autumn.

In East China, Central China, South China and the Yangtze River Basin, where the soil is basically not frozen in winter, winter planting can be done.

When planting trees, you should pay attention to pruning a part of the branches and leaves, which can reduce evaporation and maintain the moisture of the trees. The risk of planting trees is also management.

1 Characteristics of spring tree planting.

Spring tree planting refers to planting trees in the spring after the soil thaws and before the trees germinate. At this time, the tree is still in the dormant period, and it is easy to achieve the physiological balance of the aboveground and underground parts after planting. At this time, the soil in most areas of the country is in the thawing and slurry return stage, and the water conditions are sufficient, which is conducive to the survival of trees. Spring is suitable for planting in most parts of the country and almost all tree species, which is the most beneficial to survival, so spring is called the first season for tree planting.

2. Characteristics of autumn tree planting.

Autumn tree planting refers to the planting of trees after they have fallen their leaves and before the soil freezes. At this time, the tree enters the dormant period, the physiological metabolism is fragile, and the consumption of nutrients is less, which is conducive to maintaining physiological balance. Planted at this time, after a north, the root system is closely combined with the soil, and the roots are early in spring, which is in line with the phenological order of the trees that first sprout roots and then germinate.

It is not suitable for planting tree species that are not cold-tolerant and hollow in the pith.

3. Characteristics of summer tree planting.

Summer is generally not suitable for large-scale planting, and is limited to local areas and specific tree species.

4. Characteristics of winter tree planting.

In East China, Central China, South China and the Yangtze River basin, where the soil is basically not frozen in winter, winter planting can be done.

It is okay before and after Qingming, or during the season of stinging.

Cypress transplantation is usually done in early winter, when the sap has stopped flowing and is conducive to post-planting recovery.

When transplanting, the roots need to be cut off according to the size of the cypress, about 5 years old can be directly broken roots transplanted, about 10 years old, can be cut off half of the roots (referring to the number of roots) in the spring, (not all cut off and dried there), and then transplanted in the early winter. Big trees need to be divided into three broken roots before transplanting, transplantation to cut off coarse roots, fine roots, hairy roots, coarse roots can be removed, but hairy roots, fine roots should be retained as much as possible, and transplant with soil balls when starting the tree. The size of the soil ball should be 6-10 times the diameter of the base of the tree.

To prevent bark damage during hoisting, protective measures need to be taken, generally isolated with sack pieces or other felt.

When is the best time to plant with seeds.

The ease of planting depends on whether the root system is intact, the leaves are suitable, and the water is sufficient. In winter and autumn, the leaves fall off in large quantities and the metabolism of the trees slows down, which is not conducive to survival. In summer, the temperature of the seedlings is impaired, and a lot of transpiration causes the seedlings to die.

It is more suitable for spring planting, planting seedlings is not easy to dry in summer, winter trees are easy to freeze to death, and planting to survive, I don't know if I wait until next year, the efficiency is too low.

Some aspects to pay attention to when planting trees:

First of all, it is necessary to choose a suitable place, such as underground cables, cables, etc., where trees cannot be trees, at least the type of large trees can not be loaded, and trees will damage the facility. Before you have to plant trees, you have to get the consent of the landowner, because these places have their own plans, and volunteers planting trees spontaneously are like this, but also in line with local planning and development, or equal to nothing. In fact, it is necessary to plant trees in the city, it is difficult to find a suitable place, so that the seeds of trees are rich in the city, and even if they germinate, they are easy to be crushed and die, and the ability to self-renew is poor, so the balance of the urban ecology of tree plantations is necessary.

This is the best time between autumn and before bud break in spring.

The key to whether the tree planting is easy to survive is: whether the root system is intact, whether the leaves are appropriate, whether the water is sufficient, in winter and autumn, a large number of leaves fall off, the metabolism of trees slows down, which is not conducive to survival, the temperature is high in summer, the transpiration effect is large, the root system of the seedling transplanting will be damaged, and a large amount of transpiration will make the seedling dry up and die, and it is not easy to survive.

Spring is a relatively good time for planting.

In addition, planting trees is planted with saplings, which are not easy to preserve and dry up in summer, and saplings are easy to freeze to death in winter, and they don't know if they will survive when they are planted, and they have to wait until the next year, which is too inefficient.

Generally, spring and autumn transplantation is the best, the survival rate is high, and it can also be transplanted out of season, no matter when the transplant is to keep the soil ball intact, not on the root system, retain water and moisture, and pay attention to the watering of the rooting powder of the happy forest, I have used the rooting powder of the happy forest, the rooting is fast after watering, the root quantity is large, the growth is good, and the survival rate is high.

Early spring, late autumn and early winter are better, this time the leaves of the trees fall dormant and stop growing, which is conducive to survival, in fact, as long as the care is done properly, except for the midsummer season, it can survive, and the branches are more forked to be properly pruned.

Spring, before budding. Generally in March-April.

Autumn. 1. Because in autumn from October to November, when the ground temperature (soil temperature) is above 5°, the root system can produce calli and grow new roots. Especially for seedlings planted after the fall of leaves in autumn, the root system of the tree still has a period of growth before the freeze, so the next spring germinates early, and the growth is strong and the growth is large.

2. In the area north of the Huaihe River in the Qinling Mountains of China, the spring of the year is generally dry, windy and rainy, and the seedlings are easy to lose water in the process of seedling, transportation and planting, thereby reducing the survival rate and affecting the growth of the year; Autumn rainfall, rainy weather, air humidity is high, which is also one of the reasons for the high survival rate of autumn planting.

3. The autumn planting time is longer, the farm work is less, and the labor can be concentrated in the construction; In spring, there is more farm work, time is concentrated, and large-scale development and construction of gardens are susceptible to the constraints of time and labor.

The best season to transplant trees is autumn, that is, after the leaves of the trees have fallen, and when the body fluids of the trees have completely stopped moving, the weather has obviously frost, but the soil has not been frozen, and it is easier to transplant larger trees at this time. If you have a large amount of transplants, it is recommended to ask a technician to help.

The giant Juncao invented by Professor Lin Zhanxi is one of the non-often high-yield and high-quality fungi, which can be cultivated in nearly 55 kinds of medicinal mushrooms and edible fungi, in addition to being used as a material for raising fungi, it can also be used as feed, which can be used for pigs, cattle, sheep, horses, donkeys, deer, rabbits, wild boars, and various poultry (chickens, ducks, geese, quails, etc.) feeding.

It also has the characteristics of maintaining soil erosion on the planting plot, and also has a place in the field of soil and water conservation and sand fixation. Ten years ago, it was also used for energy purposes such as biopower, fiberboard, and fuel manufacturing. Its unique economic characteristics have also attracted the attention of people in related fields at home and abroad, and have also been sought after by many farmers in China.

What kind of lawn are you going to plant in the summer? The warm seasonal bai lawn is paved in the spring, and the cold season is du.

In the autumn when the temperature zhi20-25 degrees or the winter of the dao grass seeds are sown! Autumn is too cold for early autumn planting, spring is too hot for early spring planting!

Introduction to several types of turfgrass in spring and autumn.

Introduce the characteristics of several turfgrasses and their applications.

High fescue cool-season type Poaceae fescue is a turfgrass, clumping type, strong tillering, developed fibrous roots, deep soil, with wide adaptability, its cold resistance and heat resistance are strong, and it is not dormant in summer, and it is the only turfgrass species in the Yangtze River basin that can maintain evergreen in all seasons. It prefers humus-rich, well-drained loose soil, which can grow in both sunny and semi-shaded areas, and is suitable for planting large areas of green lawns. Sow.

The seed size is 30-40 grams per square meter, and it is generally sown in September-November.

Perennial ryegrass.

Cool-season grass ryegrass is a turfgrass that grows erect in clumps with fine, soft leaves and green color. Perennial ryegrass germinates and forms lawns faster than other turfgrass species. In the north, such as Beijing Changhe grassland early grass or tall fescue mixed planting permanent lawn, can improve the texture of the lawn and speed up the formation of lawn, can be sown in September and March-April.

In the transition zone area, such as Hangzhou, it is mostly used for warm season turfgrass winter sowing, and the seedlings emerge quickly, and the whole winter is dark green. Seeding amount.

About 40 grams per square meter. The season is appropriate, it depends on the grass species! Cool-season turf is suitable for autumn sowing, and warm-season turf is suitable for spring sowing.

Bud grafting is carried out in 6 September, potted plants are often grafted, and transplanted before germination in the second year. Management techniques: Potted kumquat requires proper management of water and fertilizer.

Before the germination of spring buds, cut off part of the last year's branches, leave 2 3 buds for the sturdy, and leave 3 pruned 1-year-old branches for each plant, which is conducive to spring shoot germination, and pluck the tops when the new shoots grow to 15 20 cm, so that the branches are full and hope to adopt.

Spring, the season when everything grows.

Mature and treated seeds can be propagated alive: plum can be propagated by sowing, dividing, striping, grafting, etc. It is generally used for the breeding of new varieties, harvest seeds in August and September, dry storage to sow in April of the following year, high germination rate, if the seeds are soaked in warm water first, it is easier to germinate, and the annual whole seedling is up to 20cm.

It is planted in spring and autumn and has a high survival rate.

Plum is planted in spring, which is generally sown in February and March, and seedlings emerge in April. When sowing in spring, soak the seeds of the plum blossom with warm water, soak them for about 24 hours to germinate, and then sow them in sandy soil, and the seedlings can emerge in about 15 to 20 days.

Autumn planting is usually done in July and August, when the fruit is just ripe, take the seeds from the ripe plum fruit, dry it and sow it at any time. Because the seeds are freshly harvested, fresh, and active, they can be sown at any time. Generally, 10 days after sowing, seedlings can emerge.

The transplantation of wax plum should be carried out in autumn and winter after the leaves fall to before the spring germination, and the seedlings should be brought with soil balls. The planting depth is the same as in situ. In the management to master the following three:

1 Frequent fertilization Apply fertilizer once a year in early spring and early winter, and water immediately after fertilization. For potting plants, the potting soil should be mixed with rotten leaf fertilizer and sandy loam soil as base fertilizer, and fertilizer water should not be applied in the early stage of potting. Leaf fertilizer should be applied in spring.

6 In July, a small amount of thin fertilizer water should be applied many times to promote flower bud differentiation. 2 Skillful Cultivation Techniques After the flowers are harvested in early spring, the three pairs of buds are retained at the base to promote the wax plum to pull more branches, or the top buds are removed after the new branches grow 2 3 pairs of buds to promote the germination of secondary shoots. In late summer and early autumn, the top tips of the new branches of the current year should be trimmed, so that the flower buds of the middle and lower branches are full and full.

3. Less watering Wax plum is afraid of waterlogging, and the soil moisture is too large, and the growth of wax plum is poor, which affects the differentiation and opening of flower buds. Potting soil can be kept half moisture, especially in the rainy season to prevent water accumulation.
