Soil preparation: Bahia grass can grow on a variety of soils, but sandy soil with the strongest acidity is suitable. Prepare the ground before planting to make the seedbed firm and level. It is best to apply adequate amounts of phosphorus and potassium fertilizers before planting, especially phosphorus fertilizers are essential for the growth of Bahia grass. Before planting, bury the fertilizer or soil conditioner about 10 cm below the ground surface through soil preparation, and the effect is best. It is best not to apply nitrogen fertilizer before planting, because nitrogen fertilizer can easily promote the growth of weeds.
Bahia grass is best planted in spring or early summer. If there is insufficient rainfall or good irrigation conditions, do not sow in the hottest summer, otherwise the effect of seedling emergence will be poor. If used as a lawn, the seeding rate of Bahia grass is 15g/m2, and the seeding depth is 1cm. If it is used for soil and water conservation or grazing, the sowing amount can be appropriately reduced. Within 3 to 5 weeks after sowing, a small amount of water should be irrigated several times a day. After the seedlings emerge, the frequency of irrigation should be reduced, but the amount of irrigation should be increased to promote the development of the root system of Bahia grass. The successfully established Bahia grass lawn is very resistant to drought and does not require frequent irrigation. Due to the slower germination and colonization of Bahia grass seeds, it can be mixed with about 10% of perennial ryegrass or annual ryegrass transition star to increase the plateau formation speed and reduce weed damage. Variety: Pensacola (Pensacola) Compared with ordinary varieties, it grows stronger upright and has medium-fine leaves. Its rhizome is very strong and very invasive, suitable for water and soil conservation and ordinary green space construction. It grows well on barren sandy soil, and it has a good mixed sowing effect with other grasses such as carpet grass and bermudagrass.
Cultivation technology points Choose suitable varieties, such as small-leaf varieties that are more cold-tolerant, have strong seedling reproductive ability, grow rapidly, and the germination rate of seeds can reach 50%. Large-leaf varieties have poor cold resistance and are not suitable for overwintering reproduction, but high grass yield and low seed germination rate, generally 20%, generally adopt cutting propagation. Bahia grass is mainly propagated by ramets, using stolon cuttings. Because its root is in the nodule, it is easy to survive, and the survival rate can reach 100%. The stolons can be used as cuttings every 1-2 knots, and the annual reproduction coefficient is as high as 50. Sowing and raising seedlings are strict, and the seeds must be treated with pine glume, and the germination rate is not high. The maximum sowing rate is 112.5 kg/ha. Bahia grass planting is best done from March to June, and planting in autumn can also survive. Generally 900 to 120,000 plants are planted per hectare. Turn 20 cm deep before planting, apply 375 kg of calcium, magnesium, and phosphorus per hectare, and 3,000 to 4,200 kg of animal manure as base fertilizer. After planting in summer, water should be properly watered 1 to 2 times, and weeds should be removed in time at the early stage of planting, and the surface can be completely covered after 2 to 3 months. According to the growth situation, timely application of nitrogen fertilizer 225-300 kg/ha after mowing can promote the growth of Bahia grass tiller and increase the yield of fresh grass.
