1. Plantation techniques and management of pentagrams
It would be better to plant three centimetres, four metres in length, three metres in length, two to 1. 8 metres in length, and manage it in a crude manner。
2. Cultivation and management of pentagrams
The technique of growing pentagrams
1. Cropping. The harvesting of a parent tree should be a good-quality growing stock. In the autumn, when the pentagon is converted from green to yellow, seeding takes place for two to three days and goes to the back pocket。
2. Make beds. The nursery land should be flat, easily drained, thick and fertile. Explicitly, 3000 to 5,000 kg of fertilizer per acre, 100 kg of pie, 40 kg of urea or ammonium, and flat beds。
Seeding. More in the spring. Before seeding, 50°c hot water is immersed for 10 minutes, followed by cold water for a day and a night, and then taken out to the back wind, washed once a day with warm water and mixed. Once 50 per cent of the seeds are split, they can be planted. It is broadcast from 20 to 30 centimetres in length, sowing at depths of 2 centimetres, sowing 15 to 20 kilograms per acre and covering soil of 1. 5 to 2 centimetres. Scatter the grass and keep the soil wet。
Management. Seeds can be sprung from 15 to 20 days after they are normally sowed and the grass can be removed. Saplings are available at heights of 10 cm, and seedlings range from 10 to 15 cm. After seedlings, irrigated, fertilized every 10 to 15 days, 5 to 8 kg of fertilizer per acre or 500 to 750 kg of manure per acre. (d) to cultivate, weed and control pests and diseases in a timely manner. Nitrogen fertilizer and irrigation ceased in september. It was about 1 metre tall and it was able to grow。
Technology and management methods for the cultivation of pentagrams
1. Wet protection; three days after planting, the soil has been naturally sank and, as the water has been absorbed by the surrounding soil, newly planted trees have been closely bound to the soil, and the laminates and membranes have largely been removed. In order to reduce costs, we tie the straw curtains, first by immersing them with wetness and placing them on the tree, and then placing them at an altitude of two metres, so that the workers can be on the ground and then around the thin film outside the grass curtain. The thin membranes use a general agricultural membrane, which is about 20 cm long, which is easily operated by workers and is then covered from the top to the bottom of the stairwell。
Weeding pine soil; weeding began almost in april, and weeds within the water and on the earth's piles can be removed as manually as possible, in combination with the pine soil, and weeds elsewhere can be removed with glycerine。
3 the film has been removed; in order to prevent the high temperature inside the film from burning and flaming, it is normally carried out in april, and when the tree begins to sow in large quantities, the choice is made to cut the blade open with a stick. But only above the straw drapes can be removed, and the drapes and the film surrounding them can be removed from the ground and slowly decompose。
4. Noodle fertilizers; when sprouts are made more than 10 centimetres per day, the spraying of potassium phosphate every 15 days can promote rooting and increase nutrients to increase the rate of survival. Pneumococeros or methyl tobuzines are added to the foliage to prevent disease。
5. Pest control; pentagrams are vulnerable to oxen and aphids. In may, it was largely possible to combat the phenomenon by means of a combination of artificial capture and spraying. Aphids occur throughout life over a long period of time, most easily in the growth of weak branches, with severe effects growing into plants and timely treatment。
6. Spraying water to keep it wet; amphibian mammoths are not resistant to dry and high temperatures, so that in the event of successive periods of drought and high temperatures, precipitation will become wet, and high poles can be installed with automatic nozzles that can be easily operated and reduced. Because pentagrams contain more water of their own, they tend to sprout, and the rate of survival can be significantly improved as long as the water is properly wet。
4. Pentagram planting
Pentecostal seeds are best planted in the spring and autumn, in april-june and august-october, as they are cold-resistant, and these two seasons correspond to its characteristics。
The amphibian seed has increased its activity in the spring through winter sands. Sand hides are also the process of seed seeding, where water is better preserved and seeds grow faster after seeding. The amphibian seed is harvested in the autumn and can be grown more than 20 days after planting in the spring。
The planting schedule for amphibian seeds was better in mid-april, when planting was also possible in the north, and the conditions for manual work were appropriate and the seeds were growing better. Seeds are the most dynamic and effective in spring. Seeds can grow under natural conditions, saving many seed costs。
5. How do pentagrams work? High
There are three main reasons why the rate of survival is affected by the planting of pentagrams during the summer。
1. High summer temperatures, the evaporation of leaves and the rapid evaporation of water, whether during the planting process or after conservation management, are prone to water loss。
2. During the summer, the fluid flows quickly, but the plant is not prepared to be trimmed, resulting in the loss of nutrients as a result of the spills。
3. Summer bacteria are also active, often in a hot environment in the pelvis, and are prone not only to disease but also to infection and recovery。
6. Environment and conditions for the cultivation of pentex maple
Red maple is the most suitable place to plant in a courtyard, which is already a large green plant, with small indoor space and not suitable for planting, with a red maple planted in the courtyard, making the house's wind water more fluid, and red is a celebration
The red maple is mainly the spring and autumn seasons, and the leaves look red and bright, and in summer, as the temperature rises, the leaves will have a purple and red beauty that you love。
7. Pentagram conservation planting measures
Common reproduction methods: mainly sowing. The mother tree is chosen to be grown with a strong plant growing over 10 years of age. After harvest, the fruit is tanned for three to four days, the wings are removed, the groceries are removed and stored in rooms with a moderate or slightly lower temperature, and sand is disposed of in the first 30 to 40 days prior to planting. Cultivation points: the following points should be noted in the form and maintenance of pentagrams: (1) the amphibians are less dynamic and older branches over two years old are more fragile, while the larvae are more resilient, so that they may be made sooner rather than later; (2) the general plasticization method, i. E., the main dry and large side branches are positioned and carefully managed to control the tree's position; (3) the culture environment is ventilated, the light is adequate, the heat is strong and the leaf is not sprayed in order to affect the beauty; (4), the leaves are larger, and for this reason the branches must not be kept in large amounts and the principle of the rareness and indiscretion is understood。
