Wide leaf

morphology

cattail (9)

or marsh aquatic perennial herb. Rhizome cream, white tip. Stems stout, 1-2.5 meters high. Leaves linear, leaf length 45-95 cm, 0.5-1.5 cm wide, glabrous, the upper flat portion of the back surface apply gradually raised; nearly crescent-shaped cross-section of a lower, larger cell gap, spongy; hold sheath stem.

male inflorescence close contact; male inflorescences during flowering about 3.5-12 cm, sturdy than the female inflorescence rachis bent with gray pubescence, leafy bracts 1-3 pieces, the upper short, falling after anthesis; female sequence about 5-22.6 cm, floral development; usually consists of two male stamen composition, anthers ca. 3 mm long oblong, four pollen positive fit, decoration mesh, filaments shorter than anthers, base connate stalked ; female ebracteolate; stigma of pregnancy lanceolate, 1-1.2 mm long, 2.5-3 mm long style, ovary lanceolate, ca. 1 mm, ovary slender handle, ca. 4 mm; not pregnant female ovary inverted conical, about 0.6-1.2 mm, persistent, ovary stem stout, unequal; white filaments significantly shorter than hair style. Nutlets lanceolate, 1-1.2 mm long, brown, pericarp usually no spots. Seeds brown, elliptic, less than 1 mm. Fruit period from May to August. 2n = 30.

Species and difference

This kind of external morphology near Cattail ( Typha orientalis C.Presl), however, significantly shorter than the white filaments hair style, lanceolate stigma, ovary female infertility handle thick, unequal, thick plants, leaves and other wide obviously different.

growth environment

cattail growth in lakes, ponds, canals, rivers slow flow of shallow water, wetlands and marshes also found 5261. Hi adequate light, shade intolerant, the only way plants can thrive. , Hi warm, cold-resistant, in many parts of China, it can successfully overwinter under natural conditions, the low temperature of -30 ℃.

distribution

distributed in Asia (China, Japan, Russia, Pakistan), Europe, the Americas, Oceania; distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei and Henan in China , 4102 West Shaanxi, Gansu, Xinjiang, Zhejiang, Sichuan, Guizhou, Tibet and other provinces.

breeding methods

The species to breed ramets law-based, multi carried out after the spring thaw land. The cattail rhizomes from the soil excavated, with a knife cut into the new cluster with 6-7 plants per bud can be directly colonization. We can use nursery seeding method can be carried out in the spring, summer molding seedlings can be transplanted.

cultivation techniques

planted

strong adaptability to the soil, can grow well in acidic, calcareous soil. If the conditions, the best selection of strong water-retaining clay loam. In order to avoid excessive plant growth, in the matrix should not contain too much of the organic matter. It can be planted in 4 - 5 operates in conjunction ramets months. Election should not change the water level, 2113 sunny leeward shore. Row spacing of 30 cm, 30 cm spacing digging. When planting, seedlings per hole can be placed in one, slightly repression filling, and then to irrigation. When grown as a film, you want to pay attention to its roots buds 1653 remains the same trend.

management

cattail hi shallow place, so the whole cultivation process can not make it drought. After planting put a small amount of water to keep the soil surface is covered by a state just Preferably the aqueous layer, to be about 10 cm long, then the appropriate drainage blade, so that more appropriate depth of 30-90 cm, not more than 1.5 meters. Before planting, it can be administered as basal pig. Cattail though likes big fat, but because of a strong root system absorption capacity, so in the fertilizer supply situation is not very adequate, plants can grow well. When the plants bud, it should be appropriate dressing. Skimming plants usually have to constantly remove the base of the plant moss. In the second year after planting, after Pusuo Sheng Hong broad leaf buds unearthed should be censored at those too dense to avoid excessive consumption of nutrients, affect flowering plants. Qiumodongchu, the shoot gradually yellow, then the cutting can be performed clearance process. The plant is a perennial, its root system, not aging. After its best viewing period from forming, although only a few months each year, but the place planted up to 5 years. Preferably every three years ramets once, to be updated, so as to ensure broad leaf incense Puyou Liang good growing.

Pest Control

In practice, culture, cattail difficult illness, but often suffer invasion lotus aphid pests. Control methods to improve the environment ventilation cultivation; when the rapid development of pests can be sprayed weekly 50% EC 2000 times temephos once medication is usually 1-2 times received satisfactory results. In cultivation, its roots are often grazed by geese, ducks, deer and other animals, so pay attention to prevention.

primary value

Watch: of the plant can be planted in the edge of the pond water features configured, occasionally ornamental plants.

Edible: young spikes which can be eaten, as they grow, the texture becomes more and more rough.

pharmaceutically acceptable: rhizomes can be medicine, with heat and cooling, water swelling effect.

economy: stems and leaves are produced straw, rope, Po seats, roof of good material, through the artistic process, but also woven basket, shoes, paper can and the like; inflorescence also used to produce an illumination dried material.
