Which grasses contain alkaloids?

1. Ryegrass.

It can be cultivated in most parts of the country. Ryegrass is propagated by seeds, which are divided into autumn sowing (September to October) and spring sowing (March to April), and autumn sowing is generally the best. Ryegrass has strong frost resistance, many cattle farmers agree that ryegrass can grow normally in winter, in fact, otherwise the general temperature drops below 10 when the growth will be blocked, the temperature drops below 5 will stop growing, generally early autumn sowing can be harvested 1 time before winter, can be harvested 2 3 times before midsummer, the yield per mu can reach 8000 10000 kg.

2. Sudan grass.

This kind of forage grass mainly uses seeds for propagation, generally sowing in February and April, and can be harvested 3 or 4 times a year, and the yield per mu can reach 5 10 tons. However, these forage seedlings contain a lot of hydrocyanic acid, which is easy to cause poisoning after cattle feeding, so it is best to wait until they have grown to more than 1 meter before harvesting.

3. Mexican corn grass.

It can be cultivated in most parts of the country. Mexican maize is propagated from seeds, usually in February and April, with a growing season of up to 180 240 days. Generally, it can be harvested 7 8 times with proper water and fertilizer, and the yield per mu can reach 5 10 tons.

4. Imperial bamboo grass.

Emperor bamboo grass is a perennial grass grass, because of the long leaves and high stems, the stem type is like bamboo, it is suitable for planting in most areas of the south, generally in March and June as the best planting period, planting about 2000 3000 plants per mu.

5. Alfalfa.

Alfalfa is a perennial leguminous forage, rich in protein and a variety of vitamins, so it is also known as the "king of forage", suitable for planting in most areas of our country, alfalfa uses seeds for propagation, divided into autumn sowing (8 September) and spring sowing (3 May), can be harvested 3 4 times a year, 4000 8000 kg of fresh grass or 1200 2400 kg of hay per mu, of which the nutritional value of the head stubble grass is the highest.

6. Dogtail grass.

Dogtail grass is a perennial grass grass, which has the characteristics of drought tolerance, humidity tolerance, shade tolerance, cold tolerance and trampling resistance, suitable for planting in most areas of China, and is generally best planted in mountains and hills where grazing is required. Generally, sowing is carried out in April and June, and grazing can also be harvested, and it can be harvested 3 or 4 times a year, and the yield per mu can reach 4 7 tons.

1. Mandala: herbaceous plant, 1 2 meters high, stem erect, leaves oval, summer flowering, cylindrical, corolla funnel-shaped, white, the whole plant is poisonous, the seed is the most toxic.

2. Belladonna: perennial herbaceous plant, leaves alternate, one large and one small, summer-flowering, bell-shaped, light purple, the fruit is berry spherical, black purple when ripe, its leaves and roots are poisonous.

3. Tianxian: herbaceous plants, wild in Northeast China, Hebei, Gansu and other places, the whole plant is hairy, smelly, blooming in summer, the funnel shape is yellow, and the whole plant is poisonous.

The vast majority of alkaloids are mainly distributed in higher plants, especially dicots, such as ranunculaceae, poppyaceae, self-definite, Solanaceae, oleanderaceae, rutaceae, legumes, berberaceae, etc. A very small number of alkaloids are distributed in lower plants. There are several, or dozens of alkaloids, coexisting in a plant, and their chemical structures are similar.
