What is the basis for the division of the growth period of grasses? 100

Have you received an answer? That's what I need.

Poaceous forages are rich in nitrogen-free extracts with a crude protein content of 10% to 15% in dry matter. Although the nutritional value of gramineous forage grass is not as good as that of leguminous forage, it has good palatability and no bad smell, and domestic animals love to eat it. The advantage of grasses is that they are easy to prepare hay and preserve; In addition, gramineous forage grass has strong trampling resistance and regeneration ability, and is suitable for grazing and multiple mowing.

The main grasses of the grass family are perennial ryegrass, hybrid ryegrass, Italian ryegrass, multiflora ryegrass, tall fescue, fescue ryegrass, creeping purple fescue, chicken foot grass, cattail grass, meadow fescue, ice grass, meadow grass, grass grass, African saxowe, Sudan grass, dogtooth root, elephant grass, aggregate grass, oxtail grass, etc.

Summary. Hello, dear <>

Poaceous forage: Poaceous forage is a monocot of monocots, which is a group of forage grasses, which are mainly divided into two categories: wild and cultivated. This type of grass generally has a well-developed root system, and the plants grow very tall, have long leaves, and grow luxuriantly.

The protein content of grasses is lower than that of leguminous grasses, but it has a higher fiber content and is very nutritious. High-quality forage worthy of growers.

Difference Between Leguminous Forage and Poaceous Forage.

Hello, dear <>

Poaceous forage: Poaceous forage grass belongs to monocot stuffy group, which is a group of forage grasses, which is mainly divided into two categories: wild and mill cultivation. This type of grass generally has a well-developed root system, and the plants grow very tall, have long leaves, and grow luxuriantly.

The protein content of grasses is lower than that of leguminous grasses, but its fiber content is higher, and the nutrition is also very rich. High-quality forage worthy of growers.

Leguminous forage: Compared with gramineous forage, leguminous forage grass has a slightly lower yield, but the nutritional value is higher than that of gramine, and the protein content is relatively high, and alfalfa, known as the "king of forage", is its representative. Leguminous forages should be mowed before flowering.

The main common leguminous forage grasses are: satawang, alfalfa, milk vetch, arrowtongue pea, white clover, red clover, etc. are relatively high-quality forage varieties. Second, the morphological characteristics are different:

Poaceous forage: Poaceous grass belongs to monocot plants, with soft leaves, relatively smooth round bridges, very fast growth, strong tillering force, resistance to mowing, grazing, trampling, strong regeneration ability, and high yield. Poaceous grasses are mostly suitable for grazing and multiple mowing.

Hello, dear, it's clear [than the heart].

What is the answer to this?

a Wang Dong. Hello, dear, it's clear [than the heart].

Teacher, what about this?

I haven't studied this question.

Hello, grasses can be divided into four categories, such as rhizome type, sparse bush type, dense bush type, and stoloner type, according to the tillering type, and grasses are a major group of forage grasses. It includes two categories: wild and cultivated, and the sedan chair is divided into annual, biennial or perennial. Not only resistant to mowing but also pasture, some are also excellent water potato soil conservation, windbreak and sand fixation and garden greening plants, which play an important role in the grassland ecosystem.

Poaceous plants include ice grass, finch grass, duck grass, grass grass, fox grass, rye grass, paspalum, ladder grass, early grass, dogtail grass, needle grass and so on. Do you still have any questions that you would like me to answer for you?

Summary. Hello dear dear, in September, Poaceae herbaceous plants are in the filling stage of this stage Poaceae (gramineae), is a family of monocotyledonous grass order, also known as Poaceae, known as Poaceae, known about 700 genera, nearly 10,000 species, more than 200 genera in China, more than 1,500 species. [3] About 20% of the Earth's land is covered with grasses, and grasses are known by a variety of common names"So-and-so grass"of plants .

However, it is important to note that not all grasses are grasses; Similarly, not all grasses are low"Grass", just like bamboo, can also be as high as more than ten meters, contiguous into a forest. Poaceae contains many important food crops.

In September, grasses are in the growing phase.

Hello dear dear, in September, grasses herbaceous plants are in the filling stage of this stage of Poaceae (poaceae, gramineae), quietly is a family of monocotyledonous grass order, also known as early maturing grass, known about 700 genera, nearly 10,000 species, more than 200 genera produced in China, more than 1,500 species. [3] About 20% of the Earth's land is covered with grasses, and grasses are known by a variety of common names"So-and-so grass"of plants . However, it must be pointed out that not all grasses are grasses; Similarly, not all grasses are low"Grass", just like bamboo, can also be as high as more than ten meters, contiguous into a forest.

Poaceae contains many important food crops in Xuchangyu.

And what about June.

Is it the heading period?

Yes dear.

1. Different morphological characteristics.

Leguminous forage: mostly herbaceous, a few semi-shrubs, shrubs or vines. The root system is deep and well-developed.

The stems are erect, obliquely elongated, or creeping. Leaves alternate, compound leaves, reticular veins. racemes or conical inflorescences, corolla multi-butterfly-shaped, brightly colored.

The fruit is a pod. Poaceae: The root system is usually fibrous roots.

The size of the plants varies greatly, generally 30 to 60 cm high, and the smallest is only a few centimeters, such as Orytus spp.; The highest can reach more than 4 meters, such as reeds. The stem nodes are distinct, and the internodes are often hollow. The leaves are alternate, the veins are parallel, with leaf sheaths or leaf tongues, and leaf ears in between.

The flowers are bisexual, with unisex between them, mostly panicles, followed by spikes. The fruit is usually a fruit and contains 1 seed.

2. Different types.

Leguminous forage: leguminous forage grasses mainly include red clover, white clover, alfalfa, arrowtongue pea, vetch, yellow lupine, white flower grass and wood, yellow flower grass and red bean grass, ground clover, hundred vein root, satawang, milk vetch, pillar flower grass and butterfly bean.

Poaceous forage: about 60 genera and more than 200 species of gramineous plants can be used as livestock feed, among which the most widely distributed and forage significance are: ice grass, finch wheat, duck grass, alkali grass, fox grass, rye grass, paspalum, ladder grass, early maturing grass, dogtail grass, needle grass, etc.

The main cultivated species are duck grass, mango wheat, Sudan grass, rye grass, tiqueo grass, etc.

3. The use value is different.

Leguminous forage: leguminous forage grass and its seeds contain abundant protein, with a crude protein content of more than 13% in the early flowering stage, most of which are about 20%, and as high as 25%, so they are called protein feed; At the same time, the fiber content of the book bridge is small, rich in calcium, and the fresh grass is rich in vitamins. High digestibility, excellent texture, good palatability, livestock can reach the degree of favorite food or the most favorite food, which is the first pasture.

Poaceous forage: The dry matter of grass contains about crude protein, crude fat, nitrogen-free extract, crude fiber, and crude ash, which is an important carbohydrate and energy feed. It contains more sugar and is also suitable for making silage.

Poaceae is divided into more than 620 genera and at least 10,000 species. There are more than 190 genera and about 1,200 species in China. About 20% of the Earth's land is covered with grass. Poaceae includes a variety of colloquial names"So-and-so grass"of plants .

However, it is important to note that not all of them are grasses. Similarly, not all grasses are low"Grass", just like bamboo, can also be as high as more than ten meters, contiguous into a forest.

Poaceae is the largest family of seed plants with the most economic value of the repentant cherry tree. It is the main source of human food and livestock feed, and is also an important raw material for starch processing, sugar refining, winemaking, papermaking, weaving and construction.

With the exception of buckwheat, almost all grains are grasses, such as wheat, rice, corn, barley, sorghum, etc. Pigs, cows, horses, sheep and other domestic animals also eat grass.

There are usually hollow poles with solid knots at intervals. The leaf is composed of two parts: a sheet and a sheath. The leaves come out of the knot in turn, and the leaves of the same knot are born in a plane with parallel veins.

Each leaf is divided into three parts, which are wrapped around the pole at the bottom, independent at the top, and have a thin film or ring of fine hairs in the middle. The flowers are small, there are no petals, wind pollination, and the fruit is fruitful.

Gramineae (scientific name: Gramineae) is also known as Poaceae, which is divided into more than 620 genera and more than 10,000 species, and there are about 1,200 species in more than 190 genera in China. About 20% of the Earth's land is covered with grasses, and grasses include a variety of common names"So-and-so grass"of plants .

However, it is important to note that not all grasses are grasses; Similarly, not all grasses are low"Grass", just like bamboo, can also be as high as more than ten meters, contiguous into a forest. Poaceae contains many important food crops.
