Bermuda seeds germination temperature 20-25 degrees, generally 7-10 days sprouting, about 70 days after sowing flowering. True leaves 2-3 pieces of transplanted seedlings, 4 a 5 pieces of plucking, after 2~3 times transplanting can be planted.
North China more in mid-April, late sowing in the open ground, about a week of germination, 2-3 true leaves when transplanted or interplanting, field planting plant spacing depending on the variety of tall and short in the range of 15-40cm, potted to be centrifuged, transplanted into pots, can be inverted pots once, short-stemmed species of potted plants should be repeated centrifugation to promote the birth of lateral branches, the formation of a full bush, the first of May Day flowers can be sown in early February indoor The first time I saw this, I saw it in a pot, and then I saw it in the pot, and then I saw it in the pot, and then I saw it in the pot, and then I saw it in the pot. Fertilizer is mainly phosphorus and potassium fertilizer.
Seeds should be kept in the outer round of petals began to dry, the middle round of petals began to lose color, cut off the flower head, dry to remove impurities, storage. Larkspur has a long flowering period, the late plant will decline in potential, stem and leaves messy, flowers become smaller. So fall flower beds with flowers should be re-seeded in the summer, and centering 1-2 times. Cuttings propagation can be carried out after mid-June, cut lateral cuttings, shade and rain.
Before sowing, the soil and seeds should be strictly sterilized to prevent pests and diseases during the growing period. Sowing in early April to late June can be, seed disinfection with 1% potassium permanganate solution soaked for 30 minutes, substrate with 2 parts of leaf litter, river sand 1 part, peat 2 parts, perlite 2 parts of a mixture of preparation, can be used 0. 05% potassium permanganate or 1,000 times the formaldehyde disinfection, the soil can be used in high-temperature fumigation to kill the germs, pests and grass seeds in it.
Pre-sowing substrate wet after spot sowing, bermudagrass is too light flower species, after sowing must be covered with a layer of vermiculite. At a temperature of 21 to 23 ℃, 3 to 5 days to germinate, germination does not need light, germination seedbed to maintain 50% to 60% of the water content, not too wet, in order to avoid rotting roots or sudden collapse disease.
Sowing time depends on the desired flowering time. Generally 2-3 months in advance in the greenhouse sowing. Open field direct seeding is preferred in the early spring after the cold, otherwise the seedlings are stunted; such as the use of fall flower beds, preferably in the summer seeding. Bermuda grass seed is too light seed, after sowing the mulch should be thick and dense, in order to improve the germination rate. Spring March-April. 120-130 seeds per gram, germination temperature 21-25 ℃, after sowing, 7-10 days germination, germination rate of 60%.
Sowing to flowering depending on the variety, from 45-75 days. Spring sowing is carried out in March-April, 4-5 leaves when transplanting, plant spacing 10 cm. early June planting, plant spacing 3030 cm. During the growth period every 10 days to apply 10 times the liquid human feces and urine. flowering from July to frost. Bermuda can also be used in the summer side branch cuttings propagation, but because of high temperatures and showers, should pay attention to the protection of shade.
Seedlings grow 1 piece of true leaves, seedling transplantation once, 100 days grass root system is not developed, less lateral roots, generally in 2 pieces of true leaves when transplanting planting pots, transplanting should be with soil, transplanting substrate should be loose, fertile, well-drained, available pond mud 3 parts, 1 part of the rotting soil, rotting heap of stables fertilizer 1 part of the preparation of the depth of the planting in the cotyledons under the 0.5 cm, planting light pressure after the soil, watering. Dwarf species plant spacing of 30 cm, tall stem species 50 cm. After planting, apply leaf fertilizer once a month (rotted soy sauce residue, etc.). In order to promote plant dwarfing, branching, but also in the seedling spraying B9100-500 times liquid.
Dwarf bermudagrass should be centered several times, the first time at 6 leaves, leave 4 leaves centered, *** centered 2 to 3 times, each centered after the application of potassium dihydrogen phosphate, especially buds to bloom, every 5 to 7 days to spray 0. 2% potassium dihydrogen phosphate. Fertilize to prevent disease. After plant growth stabilization, the soil should be kept moist, watering once in the morning and evening in summer, the seedling period every 5 to 7 days to apply 200 mg / liter of nitrogen fertilizer and organic liquid fertilizer, after 2 to 3 times to switch to composite fertilizer, the summer season is appropriate to apply thin fertilizer, fertilizer instead of water.
Looks like the sowing method of bermudagrass is very complicated, in fact, it is not difficult to understand, if there are different opinions or methods, please point out, I hope to give the flower friends a good platform for exchange.
