A plant of the sedge family, but I don t know which one it is, please ask the big guy passing by for

Hello, this looks like Surinamese sedge, a sedge plant in the family Cyperaceae. Mostly grows in moist living swamps.

1. Morphological characteristics of Surinan Souris grass

The plant is slender, erect, and erect. The leaves resemble grasses, with variable morphologies, with long rod-shaped stems with a triangular cross-section, linear leaves that stretch radially, and grow at the top of an upright petiole like an umbrella bone. The flowers grow at the end of the leaf clusters, bloom in summer or autumn, and the fruits are brown.

2. The growth environment of Surinan sand grass

Surinan sand grass is afraid of direct sunlight, because it is originally an aquatic plant, it needs to be planted in water, taking water tank planting as an example, the medium needs to be soaked in water at least 10 cm.

In terms of moisture, it is necessary to keep the soil highly moist, to prevent water from being dispersed and lost to the drainage holes, and to spray foliar moisturizers frequently. It is not cold-tolerant, and if the temperature is below 10 degrees, it needs to be cultivated in a warm place all the time. Sedges are mainly propagated by divides and can be carried out every spring.

3. Cultivation technology of Surinan sand grass

1. Planting. Sedges are often used in the decoration of ecological pools, which can be matched with plants such as lotus flowers and purple taro, forming a harmonious and symbiotic "miniature natural" environment. Sedges are suitable for planting in shallow water at a depth of 10-20 cm.

If the sedge is used for interior decoration, it can be planted with a refreshing medium such as clean soil after washing the roots, and the sea and Wigan burst rooting agent can be used to help more roots, enhance growth, and show the beauty of sedge in bare roots.

2. Watering. When raising Surinamese sedges, it is necessary to always pay attention to whether the roots are well hydrated, otherwise it will lead to poor plant growth and unsightly plant shape.

3. Pruning. The focus of appreciation of Surinan Sand grass is not only on the leaves, but also on the overall plant shape effect, which is suitable for multi-plant groups, and when necessary, the plants can be pruned to highlight the three-dimensional effect.

Look at the broken rice sedge (Latin name: Cyperus iria L.).）：

It is an annual herb of the family Cyperaceae of the class Monocots, without rhizomes and fibrous roots. The stalks are clustered, weak or slightly stout, 8-85 cm high, flattened and triangular, with a few leaves at the base, the leaves are shorter than the stalks, 2-5 mm wide, flattened or folded, leaf sheaths reddish-brown or brownish-purple. The small nuts are obovate or oval, triangular, equal to the length of the scales, brown, with dense micro-protruding fine spots.

The flowering and fruiting period is from June to October.

Cyperaceae weeds are a relatively common plant in life, so what are the common sedge weeds? 1. Heteromorphic sedge, generally distributed throughout the country, has a relatively soft texture, a multi-headed inflorescence at the top, relies on seeds to reproduce, and the suitable temperature for germination is between 30 and 40 degrees. 2. Fragrant aconite, which spreads relatively quickly, can germinate in the range of 13 degrees Celsius to 40 degrees Celsius, and is a malignant weed.

3. Firefly is distributed in the north and south of China, and when it is ripe, it is black-brown and shiny. 4. Flat-stalk grass is distributed in all parts of China, and can germinate in the range of 20 degrees Celsius to 30 degrees Celsius. 5. Broken rice sedge, the leaves are basal and arranged in a triangular shape.

The blades are narrow-stripped. It is distributed in most parts of the country, with strong cold tolerance and humidity tolerance, and is a moisture-loving weed, which grows rapidly in the rainy season.

1. What is the difference between Shaaceous weeds, Poaceous weeds, and broad-leaved weeds.

We know that weeds are mainly divided into grasses, sedge weeds, and broadleaf weeds in weed chemical control, and their simple differences are:

1) Poaceous weeds:

Characteristics: the stem is round or slightly flattened, the nodes and internodes are clearly distinguished, the internodes are hollow, the middle sheath is open, and there is often a leaf tongue. The embryo has 1 cotyledon, the leaves are narrow and long, parallel veins, the leaves are sessile, and the roots are fibrous roots, such as barnyard grass, horsetail, cow tendon grass, dry ripe grass, etc.

2) Cyperaceae weeds.

Characteristics: The stem is triangular or oblate, without the distinction between nodes and internodes, and the stem is often solid. Some are cylindrical and hollow.

The leaf sheath is not open, and there is no leaf tongue. The embryo has 1 cotyledon, the leaves are narrow and long, parallel veins, and the leaves are sessile. Such as fragrant aconite, broken rice sedge, water centipede pine, etc.

3) The main morphological characteristics of broad-leaved weeds are round, heart-shaped or diamond-shaped, leaf veins are usually reticulated, and stems are round or quadrangular (square). Such as hollow lotus seed grass, one-year canopy, drop vegetables, etc.

Among them, grasses and sedge weeds are also collectively referred to as monocotyledonous weeds. Broad-leaved weeds are also known as dicot weeds.

So what is the difference between monocotyledons and dicots?

We know that angiosperms (most plants are not angiosperms) are divided into dicots and monocots. The fundamental difference between them is the development of two ** leaves or one ** leaf in the embryo of the seed, two are called dicots, and one is called monocots. The former are such as apples and soybeans; The latter are like rice, corn.

These two types of plants are relatively easy to distinguish because there are some distinct morphological differences between them. The root system of dicots, which is basically straight, has a well-developed taproot; Many are woody plants, and the stems can be thickened; The leaf veins are reticulated; The number of sepals and petals in the flower is 5 or 4, and if the petals are combined, there are 5 or 4 lobes. The root system of monocots is basically fibrous root system, and the taproot is underdeveloped; Mainly herbaceous plants, woody plants are few, and the stems usually do not thicken year by year; The leaf veins are parallel veins, and the number of sepals and petals in the flower is usually 3, or a multiple of 3.

The above differences make it easier to distinguish between monocots and dicots.

Monocots Dicotyledonous classes.

1.Embryo 1** leaf 1Embryo with 2** lobe.

2.The taproot is underdeveloped and forms a system of roots 2The taproot is well developed and mostly has a straight root system.

3.Vascular bundles are scattered, without formal layers 3The vascular bundles are arranged in a ring-like pattern with cambium.

4.Leaves with parallel or arcuate veins 4The leaves are reticulated.

5.Flowers often count 3, less 4 counts, no 5 numbers 5Flowers are often counted in 5 or 4 counts, and rarely 3 counts.

6.Pollen has 1 germination hole 6The pollen has 3 germination holes.

In the whole angiosperms, the species of dicots account for 4 5 of the total, and in addition to almost all trees, there are many fruits, melons, fibers, oil plants, and many vegetables; Whereas, monocots have a large number of food plants, such as rice, corn, barley, wheat, sorghum, etc.

Two: common gramineous weeds of gramineous weeds.

Wild oats are an annual herbaceous plant.

Poaceae stem-shaped, hollow, knotted, leaf sheath, leaf row often has leaf tongue nucleus, fruit is.

The two families are very similar, but differ in the following points:

The cross-section of the stems of sedges is mostly triangular, and the arrangement of leaves is mostly triangular (called trinumerality).

Poaceae is a dinumeric species.

The stalks of sedges are mostly solid.

Poaceae are mostly hollow.

The stems at the base of the leaves of sedges are curly, usually with closed leaf sheaths and elongated leaves, and some have only sheaths and no leaves.

Most of the grasses are leafless.

The scales on the periphery of the sedge fruit will shed the scales on the periphery of the gramineous fruit when the fruit is ripe and falls, and usually do not fall off when the fruit is ripe and falling, but these two families of plants have few obvious characteristics in appearance except for the spikelets formed by flowers, so it is quite difficult to supervise.

What are the sedge plants.

Cyperaceae plants generally have fruity stems, many leaves, relatively small flowers, and good adaptability. Pyrophorae plants include water chestnut, oil sedge, head sedge, alpine sedge, oil sedge, moss, yellow sedge, heterophyllous sedge, cow felt, and lowland sedge.
