2. Growing environment:
White clover likes warm and humid climate conditions, and the area suitable for growth is neither too hot nor too cold, with sufficient water. The lowest temperature of seed germination is about 65438 00℃, and 20-25℃ is the most suitable. When the temperature is over 35℃ or below 10℃, the germination is not good. Not hardy, easy to freeze to death in northern China. In Nanjing, when the lowest temperature in winter is -7℃ to-13℃, only the tip of the blade freezes.
The growth of Trifolium repens needs more water, and the suitable distribution area is where the annual precipitation is above 600 mm, and 700- 1000 mm is the most suitable. If the soil is too wet, it will not grow well, and it will not tolerate waterlogging and mild drought. White clover likes neutral soil with good drainage, deep soil layer and rich humus. It is not suitable for the soil to be too sticky or barren, and it will not grow well if the soil is too acid or too alkaline.
3. Main values:
Feed: White clover is an excellent forage with strong adaptability. [ 1]? The crimson clover hay at flowering stage contains crude protein 16.55%, crude fat 3.62% and nitrogen-free extract 4 1.43%. The digestibility is also high, with crude protein 69%, crude fat 43%, crude fiber 56% and nitrogen-free extract 65%.
Ecology and appreciation: Trifolium pratense has high nitrogen content and fast decomposition, which can be used as green manure in rice fields. Because of its dense stems and leaves, long green period and bright colors, it is also an excellent lawn plant and honey source plant. Strong soil protection and consolidation, also used for soil and water conservation.
