Common varieties and habits of mixed lawn
★? Poa pratensis: Poa pratensis is a kind of lawn grass with excellent performance, which is used in many places when mixed sowing lawn. It accounts for 60 ~ 70% of mixed grass seeds, with a very high proportion. Poa pratensis has a long green period and strong resistance, but its growth rate is slow, so it can germinate in advance before sowing.
★? Festuca arundinacea: Festuca arundinacea is also an available mixed sowing variety. Its leaves are delicate in texture and more barren-resistant, but tall fescue is easy to be infected with pests and diseases, so it should be used as appropriate.
★? Festuca arundinacea: Festuca arundinacea has good heat resistance, especially in summer, and its growth state is better than other cool-season lawns. Festuca arundinacea can be properly added to the mixed lawn to improve the overall heat resistance of the lawn;
★? Perennial ryegrass: Perennial ryegrass has the fastest germination speed and strong competitiveness. If the proportion of seeds is too high, it will easily affect the growth of other grass species and can be reduced appropriately.
Technical points of mixed sowing lawn:
1, pay attention to the principle of competition and complementarity of mixed lawn. When matching lawns, we should consider the complementarity between different varieties. If some varieties have poor cold tolerance, some varieties with strong drought tolerance should be properly matched. In addition, these grass species grow together and have a competitive relationship, so we should consider their competitive ability and control the proportion of those grass species with strong competitiveness.
2. Determine the proportion of mixed sowing according to the characteristics of lawn. The characteristics mentioned here mainly refer to the growth speed, leaf texture, leaf color, pruning resistance and disease resistance of lawn. Try to choose lawns with high uniformity to match each other and coordinate their species ratio.
3. Pay attention to the sowing time. If it is a mixed lawn, it is best to catch early spring or early autumn, when the soil moisture is better and the temperature is more suitable.
4. Master the rhythm of pruning. Pruning work is mainly concentrated in spring and summer, and the lawn should be trimmed once before entering winter.
5. Pay attention to the problem of lawn degradation. It is necessary to plan well in advance, pay more attention to check the lawn at ordinary times, and take preventive measures if some varieties are found to be degraded.
