How is willow cultivated? Strange willow also has a very "Buddhist" name, that is, Guanyin willow, China's Shandong, Hebei, Liaoning, Henan and other regions have wild. Strange willows can be used for landscape viewing or can be made into bonsai.
1 Variety characteristics
Tamarix has wide adaptability and strong stress resistance, Tamarix is not strict for climate and soil requirements, and can grow in clay loam, sandy loam and riverside alluvial soil, with the advantages of light-loving, drought-tolerant, salinity-tolerant, barren- and thin-resistant, water-resistant, hardy, hardy, wind-resistant sand and sand.
2 The value of Tamarix
Tamarix has strong reproductive ability, can be planted in the same year, flowered in the same year, and fruited in the same year, and has great economic and ecological value. Economically, the branches and leaves can be used as livestock feed, young branches and leaves can be medicated, wood can be used as paper materials, and roots can be made of root carving; ecologically, the root system is huge and can prevent wind and sand fixation, purify water quality, branches can absorb pollutants and toxic substances, purify the air, have a long flowering period, beautiful flower color, and have a good beautification and greening effect.
3 Cultivation techniques of Tamarix
Tamarix can be propagated by means of cuttings, sowing, striping, plant splitting, etc. In the afforestation of pieces, there are mainly cuttings afforestation, direct afforestation, seedling afforestation and other ways. The Jixian area adopts seedling afforestation, and the source of seedlings comes from Shandong. Afforestation of seedlings is divided into 2 kinds of afforestation of spring digging seedlings and afforestation of winter storage seedlings, the method is to select 2 annual healthy seedlings, requiring the height of seedlings to be about 1m, the diameter of the ground is more than 0.5cm, the root system reaches more than 15cm, according to the growth trend of seedlings, according to the 10cm × 10cm standard digging pit, the plant distance is maintained at about 1m, and the row spacing is 1~2m. Although tamarix is easy to manage, but the management of water and fertilizer is essential, especially in the first 3 years of planting, it is very necessary to manage its careful water and fertilizer, can accelerate the growth of plants, conducive to the formation of a good plant shape, after 3 years into normal management, just rely on natural precipitation, if not long-term drought, without special watering. Tamarix young branches are fragile and fragile, in the first 3 years after afforestation, we should pay attention to strict management, sealing, to prevent trampling, while paying attention to loose soil, weeding and control of diseases and pests 4 main pests and control measures Tamarix management is relatively extensive, common diseases are: powdery mildew, branch blight, black blight, rust, etc.; pests are: yellow poison moth, orange yellow poison moth, tamarix leaf beetle, tamarix white brow bug, etc.
4.1 Powdery mildew
(1) Remove the source of infection. Combined with autumn and winter pruning, diseased branches and fallen leaves are removed and destroyed centrally.
(2) Strengthen management. Timely increase the application of phosphorus and potassium fertilizer, ventilation and light transmission.
(3) Spray control. Spray 5°be stone sulfur compound before germination to eliminate the source of overwintering bacteria; spray 2000 times liquid with 25% powder rust rather wettable powder, 50% dextrin 800 times liquid or 25% carbendazim wettable powder 500 times liquid during the growing season, spray once every 15 days, spray 2 to 3 times.
4.2 Blight
(1) Strengthen cultivation management and improve disease resistance.
(2) Pharmaceutical control: 50% Daisen ammonium or 65% Daisen zinc wettable powder 1000 times liquid, 70% Bacillus Qing wettable powder 500 times liquid spraying, control disease development.
4.3 Rust
(1) Remove the source of infection. Combined with pruning, timely removal of diseased branches, diseased leaves, etc., centralized destruction.
(2) Pharmaceutical control. Spray 0.3% sodium pentachlorophenol mixed with 1°be stone sulfur compound during the dormancy period, spray 25% rust ninjutsu powder 2000 times liquid and 65% daisen zinc wettable powder 500 times liquid during the growing season.
4.4 Yellow ancient poison moth
(1) Eliminate the overwintering insect body, use the habit of larval clusters to overwinter, combined with winter pruning, scrape off the eggs of poisonous moths, and search for overwintering larvae.
(2) Lights trap adults. Use black light or frequency vibration insecticidal lamps to booby trap the kill.
(3) Protection of predators. Such as: poisonous moth red-eyed bee, caterpillar chase fly, wildebeest wasp and so on.
(4) Using the habit of larvae up and down the tree, the plastic film is blocked and removed in the collection of tree trunks.
(5) Pharmaceutical control: 20% sterilization urea No. 1 5000 ~ 8000 times liquid, 10 billion / g of cyanobacteria 500 ~ 800 times liquid in the larval stage, 40% chrysanthemum 2000 times liquid, spray control.
4.5 Tamarind leaf nails
(1) Eliminate the source of overwintering insects, remove adult insects from stone bricks, weeds, fallen leaves, etc.
(2) Protection and utilization of natural enemies.
(3) Light booby-trap adult insects: use black light or frequency vibration insecticidal lamps to trap and kill.
(4) Chemical control: 50% acarburicide thiophos emulsion 800 times liquid, 40% acetamin phosphorus emulsion 800 times liquid, 40% rapid culling 1500 times liquid, etc., spray prevention and control.
4.6 Tamarix white-browed bug
(1) Strengthen nurturing, reasonable fertilization, and reasonable mixing of a variety of qiao, irrigation and herbs.
(2) Pay attention to protect predators. Such as: all kinds of ladybugs, jumping wasps, tassel wasps and so on.
(3) Chemical control: 25% iminothion 1000 times liquid, 50% acetyl methylphos 1000 times liquid, 20% permethrin 2000 times liquid, etc., spray control.
