How much is a pound of alfalfa

Alfalfa prefers warm and semi-humid to semi-arid climates, so it is mostly distributed in the area north of the Yangtze River and has a wide adaptability. In areas with less rainfall, drought can also be tolerated. It has strong cold resistance and can withstand winter temperatures below minus 30 degrees Celsius. When covered with snow, it can safely survive the winter even when the temperature reaches minus 40 degrees Celsius. It can be grown in the three northern regions of Northeast China, North China and Northwest China, and is more suitable for the plains and black soil areas. The hot, humid and cold climate in southern China does not allow for good growth and development, so it is less planted. In cold areas with little snow in winter, plants often suffer from cold damage in spring due to severe climate changes. Therefore, it is necessary to use cold-resistant varieties or take appropriate protective measures to survive the winter. The rhizomes of alfalfa are relatively developed, with roots distributed throughout the 0-75 cm soil layer, accounting for about 60% of the total root mass.

Grass seeds are the seeds of grass. So how much does it cost per kilogram on the market? What kinds of plants are there? How to plant them better?

According to statistics, different varieties have different prices, and different discounts apply depending on how much you buy. Currently, the price of lawn seeds on the market ranges from a dozen yuan to sixty or seventy yuan. Among them, the more affordable ones include Evergreen, Slope Protection King, Tall Fescue, Manila, etc., which can be used for planting on football fields or large areas of vacant land to preserve soil and prevent wind, and have a high cost-effectiveness ratio. Among them, some of the higher-end grasses include green grass, carpet grass, creeping bentgrass, and bermudagrass. Among them, green grass is resistant to trampling and is suitable for landscaping in villa walking areas or planting in golf driving ranges.

Purple hibiscus has lush flowers and leaves. When planted on a large scale, the ground should be covered quickly, especially because Purple hibiscus has dense, small and easily wetted leaves, and has a large water holding capacity, which can effectively intercept rainfall and reduce surface runoff. It is worth mentioning that the rhizome of purple-shoukai is also relatively developed. Roots and rhizomes fix nitrogen and increase the organic matter content of the soil. A large number of lateral roots meander to form a strong rhizome network and nitrogen fixation effect, which is not only beneficial to the formation of soil colloids, but also can improve the physical and chemical properties of the soil, increase the water solubility and water absorption of the soil, and thus play a role in maintaining soil water.

In addition, purple first Kai has strong adaptability and can be planted in a wide area. It can still grow vigorously after being harvested several times or destroyed during the growth period, and has strong regeneration ability. It is actually a high-quality environmental protection plant in poor areas.
