Garden use
Edge tree
Willow is luxuriant in foliage, its flowering period is as heavy as snow, and its flowers are slender, beautiful and lovely. It is a beautiful ornamental tree species in the garden, and it has a good ornamental effect whether it is decorated or planted in groups. Several plants should be planted in clumps on the lawn, and it is also suitable for scattered planting on the roadside, beside the pool and around the building.
Breeding and cultivation
Propagation by sowing, cutting or grafting. The height of seedlings is about 30cm, so cutting should be carried out in summer. Grafting with Fraxinus mandshurica or Ligustrum lucidum as rootstock. Transplanting is carried out in spring and autumn, and big seedlings need to plant soil balls.
Key points of cultivation
To propagate by sowing or cutting. Sow, usually immediately after harvest, or mature after sand accumulation, and sow in the following spring. Cutting should be carried out in the rainy season, and the thick and semi-mature branches of that year should be selected for cutting in sandy loam in the open field. Seedlings can be transplanted in spring and autumn. Small and medium-sized seedlings need to be transplanted with soil, and large seedlings need to be transplanted with soil balls.
Application value
This willow is tall and beautiful, with lush foliage. Early summer is full of white flowers, such as frost and snow, beautiful and pleasant. It is suitable for planting around buildings, or beside Chi Pan and sidewalks in parks. You can also choose old piles as potted plants and pile landscapes.

Edge tree
Chimonanthus praecox, alias tunnel flowers and trees, shredded radish, beef tendon, black gold, tea tree, April snow, etc. Salix, Meliaceae. Fringe is a rare tree species unique to China, which is masculine, cold-resistant and deciduous. Its plant height can reach 20 meters, its bark is grayish brown, its branchlets are grayish yellow and densely villous. Leaves opposite, leathery, elliptic or obovate-elliptic, entire or sometimes serrated. Petiole base is purple, flowers are white, cymes are terminal. The stone fruit is oval, blue-black, with a flowering period of April-May, a flowering period of about 10 days, and a fruit maturity of 9- 10 months. There are tassel seedlings in Tanghe Town, Hedong District, Linyi City, Shandong Province, which is the largest tassel seedling base in Jiangbei, with an annual emergence rate of 6.5438+0.0000 plants. The author summarizes the long-term practice of tassel seedling raising technology and its application as follows:
1. Propagation methods can be divided into sowing and cutting.
Edge tree
1, sowing and seedling raising: 1. 1 The seeds mainly come from Henan, Shanxi, Shaanxi, Hebei and other places. According to the experiments in recent years, the average germination rate is 1000 grains/kg, the maximum is 700 grains per kg, the minimum is 1798 grains, and the average is 1249 grains. 1.2 seed treatment: harvest seeds from September to June. Water separation is carried out after harvesting. The method of water separation is: soak the seeds for 48 hours and add 0. 1% potassium permanganate to disinfect the seeds. In the process of soaking, the seeds with low maturity and insects are floated and fished out to get pure seeds. At the same time, combined with soaking, the brown epidermis on the surface of seeds is ground off by hand to facilitate seed germination. 1.3 Seedling raising method 1.3. 1 Method 1: Push the roots and choose a place with good leeward and sunny drainage. Dig a pit with a depth of 10cm, and the length can be determined according to the number of seeds. Mix tassel seeds and clear water sand (sterilized and sieved) evenly according to the ratio of 1:2, and pour them into the pit for even distribution. Some grass targets can be erected in the border, which is ventilated and breathable to prevent seeds from rotting and the surface layer from being soaked by dry pouring. 1.3.2 Method 2: Accelerate germination, choose the leeward and sunny place as the border, sprinkle pure seeds evenly in the border every two days after watering, cover with 0.5cm soil, then cover with 0.5cm sand, and cover with plastic film. Always observe and pay attention to the dryness and humidity of the soil, water it after drying, and pay attention to weeding and loosening the soil to ensure the germination rate of seeds. Edge tree
The experiment shows that: Method 1: After two months, the roots of tassel seeds are basically all born, and the roots can reach 4-5cm. At this time, the seeds in the border can be taken out and the seeds with roots can be selected for planting. You can also take it out and plant it in the future. This method can be planted from autumn to the following spring. It was not busy farming years ago, saving labor, planting slowly years ago and planting fast years later. Method 2: By the end of March of the following year, the seeds basically broke through the ground and strengthened management. By the beginning of May, when the leaves grow to 3-4 leaves, they will be planted directly in the ground. Comparison: Both methods showed good results in the process of tassel seedling raising. The overall experimental comparison shows that after transplanting, the second method is not as good as the first method, and the seedlings grow vigorously. The first method urges the roots, and the seedlings emerge vigorously after sowing. The second method is small seedlings, which need a certain delay in seedling stage, but the second method has the advantages of high germination rate and orderly emergence. The first method saves land and avoids the busy farming season. The second method consumes a lot of land, which coincides with the busy farming season. 2. Cutting seedling: This method is mostly carried out in rainy season. The method is to select the semi-lignified branches of the year and use sandy loam as the matrix, but this method is rarely used. First, it can only adapt to some varieties; Second, the stability of the original variety after cutting is not strong.
Second, the planting method
Edge tree
Leveling fields, watering and planting 22,000 plants per mu; Plant spacing is 30cm×10cm; ; After 2 years, the osmanthus rootstock can be grafted. If the green seedlings are cultivated, they can be transplanted from them year by year, and the big seedlings should be transplanted according to the plant spacing. Seedling transplantation should be carried out in spring and autumn, medium and small seedlings with soil and large seedlings with soil balls. In the process of planting, if tassels are used in the future, the first seedling raising method can be used to cultivate bonsai. The method is to put the root tip into the soil 1cm when planting roots, then turn left and then right for the remaining roots, and plant according to the mound in the soil. Two years later, when the male spike seedlings were grafted in the pot, the curved root system was carried out of the soil, forming a common phenomenon. Willow likes fertilizer, so it should be cultivated and weeded in summer to keep the soil loose. 1 year-old seedlings can grow to 0.8-1 .2m, ground diameter1cm, and grow to 3-4cm in three years, which is used for greening.
Third, pest control.
Edge tree
Scarab is the biggest pest of willow seedlings. After emergence, when the seedlings grow out, the roots will be bitten off in May. The common control methods are to prepare a solution with phoxim, then irrigate the roots, apply 2 kilograms of water per mu, or spray trichlorfon 1000× liquid to control adults. Application: 1, landscaping purposes: willow is luxuriant in branches and leaves, with large and beautiful flowers as snow, small and dense flowers, and the flowering period is about 10 day. It is an ideal tree species to beautify the environment. Whether as street trees or as decorations, group planting has a good ornamental effect. Spike has strong adaptability, drought resistance and cold resistance, and can be widely popularized and applied from the north of the Yangtze River to Beijing. 2. Grafting Osmanthus fragrans The rootstocks used for grafting Osmanthus fragrans are mainly tassel, ash and Ligustrum lucidum. Years of experiments show that grafting osmanthus fragrans with tassel as rootstock has good affinity, compact crown shape, drought resistance and cold resistance, strong adaptability and life span of more than several hundred years. Osmanthus fragrans grafted with Fraxinus chinensis and Ligustrum lucidum "has short life span, defoliation in winter, late flowering, few pale flowers, underdeveloped roots and is not easy to be potted." 3, the material is hard and heavy, the texture is meticulous and beautiful, and it can be used to make utensils and joinery. 4. Young leaves can replace tea as a beverage, and the fruit has high oil content, which can be used for oil extraction industry.
