Trifoliate biological characteristics

Trifoliate lawn is a perennial herb of the family Leguminous Clover. Light green, plant height 30-60cm, leaves smaller, three compound leaves, leaves with gray "V" word markings, flowers are red or light purple.

The three-leaf lawn is warm and humid, and it is most suitable for areas that are not very hot in summer, warmer in winter, and have an annual rainfall of 1000 mm and have irrigation conditions. Medium cold resistance, the optimum growth temperature is 20-25. C.

The clover has lax soil requirements, but it is most suitable for planting on well-drained, fertile soils rich in calcium and clay loam. It can also grow normally on loamy soils and relatively barren sandy lands. Neutral to slightly acidic soil, suitable soil pH value of 5.5-7.5. Strong acid, strong alkali or excessive groundwater level will affect its good growth.

Suitable cultivation area

It can also be used as a ground cover for parks, orchards and forests. It can also be used for highway slope protection, bank protection, etc. The soil and water conservation, at the same time, excellent adaptability and trampling resistance make it a good quality pasture.

Building management technology

The clover can be sowed in spring or in autumn. It is better to sow in spring in the alpine and warm mountain areas, and autumn in areas where there are few frosts in winter and water conditions. Seeding rate 0.8-1.0 kg/mu. When mixed with other grass seeds, the seeding rate should not exceed 15% of the total seeding amount. It is best to inoculate white trifoliate rhizobia before sowing. The seedling growth rate is relatively slow, and the seedlings are mainly rooted for nearly one month. Weed damage is more serious at this time. Therefore, weeds should be guarded before and after sowing. Suitable trim height is 3-5cm.
