Leguminosae is an annual or perennial herb of Trifoli-um. The most widely distributed forage grass can also be used as green manure (see color clover). Native to South Asia Minor and Southeast Europe. There are about 36 species in this genus, among which about 25 species are of agricultural value, and three species, namely red clover (T.pratense), white clover (T.repens) and crimson clover (T.incarnatum)3), are widely cultivated. In addition, there are T.hybridum and so on.

red clover is also called red clover. Distributed in Europe, America, New Zealand, etc. South of Huaihe River in China is also cultivated. The stem is erect or inclined, round and with concave and convex longitudinal stripes, 6 ~ 1 cm high. There are pale white V-shaped markings on the leaflets, and the leaves are hairy and entire. Head, with more than 1 flowers, reddish purple, self-flowering. Pods are obovate, with membranous pericarp and 1 seed per pod. The seeds are kidney-shaped or nearly triangular, yellow-brown, and the 1-grain weight is about 1.5 grams.

likes humid and warm climate, and is more drought-resistant and cold-resistant. It is suitable for the growth of cohesive soil with good drainage and rich calcium. The growth cycle is generally 2 ~ 6 years, and it is often shortened to biennial or annual under warm conditions. Red clover is a long-day crop, which can blossom and bear fruit only after more than 14 hours of sunshine. When used for livestock forage cultivation, it is generally mixed with Gramineae forage; Used as green manure or feed, it is often cultivated alone. Inoculation with rhizobia can obviously increase the yield. Sowing can be done in spring and autumn, and the sowing amount per hectare is about 15 kg. The row spacing of drilling is 2 ~ 4 cm and the depth is about 1.5 cm. It can be mowed 2 ~ 4 times a year. The stems and leaves are soft and slightly bitter. Fresh grass contains about 4.1% crude protein, 1.1% crude fat, 7.7% crude fiber, 12.4% nitrogen-free extract and 2.% ash. The yield of fresh grass per hectare can reach 3 ~ 6 tons.

white clover is also known as red clover. It was first cultivated in Holland in the late 16th century, and now it is widely distributed in temperate regions. It is cultivated in the south and southwest of Huaihe River in China. Perennial herbs, rooting on the ground. The stem is slender and soft, creeping on the ground, and the plant is 3 ~ 6 cm high. The petiole is long, the leaflets are obovate or nearly obcordate, and the leaf margin is serrate. Head with 1 ~ 8 flowers, white or purplish red. The pod is obovate and rectangular, with 3 ~ 4 seeds per pod. The seeds are nearly round and yellow, and the 1-grain weight is .5 ~ .7 g. I like warm and humid climate, with wide adaptability and strong acid resistance. The soil with pH4.5 can still grow, and all kinds of soils with good drainage can grow except saline-alkali soil. Good reproducibility, trampling resistance, belonging to grazing pasture. Before flowering, fresh grass contains crude protein 5.1%, crude fat .6%, crude fiber 2.8%, nitrogen-free extract 9.2% and ash 2.1%. Although the yield is not as good as that of red clover, it has good palatability and high nutritional value.

crimson clover is also called crimson clover. Originated in Europe, distributed in northeast Europe and North America. China Huaibei and the south of the Yangtze River are widely introduced and cultivated. It can be used as pasture, ground cover vegetation or green manure, and can also be used as idle crops. Annual or perennial herbs. The stem is round and hollow, about 7 cm high. Leaf blade is nearly round, with short hairs on both sides, large petiole, round and large stipules, and membranous. The head is cylindrical with crimson flowers. The pod is obovate and contains 1 seed. The seeds are round, yellow or brown, and the 1-grain weight is 3.2 grams. Like warm and humid climate, barren and shade-tolerant. In bud stage, fresh grass contains crude protein 3.%, crude fat .6%, crude fiber 4.7%, nitrogen-free extract 7.4% and ash 1.7%.

< -chick it

I once found a real four-leaf clover.

It was the day after my grandmother's funeral.

In the yard that she had carefully cared for

but now it was a little desolate,

I found a four-leaf clover,

It looked smaller and weaker than other clovers,

I carefully put it in the book,

and after a while, I lost the soil and water.

Can this fragile little creature

really bring happiness to people?

I believe the sadness and beauty brought by that story, but

I deny its realistic significance.

The real life can't be obtained by praying.

What's more, it is an abstract concept of "happiness"?
