Dancing grass cultivation techniques
First, sowing time and temperature: General 3-10 months sowing is appropriate, the south can be sowing the four seasons, the seed germination temperature is above 20 °C, there are conditions available greenhouses or modern facilities to control the temperature moisturizing, so you can sow in advance or in batches. Second, the seed treatment: dancing grass seeds hard, the appearance of a bright wax, in natural conditions, it takes several months to emerge. To make it germinate quickly, soak it with dry hot sand or sizzling (within 38°C) before sowing to remove the wax from the seeds, or place the seeds on the concrete floor and gently turn it with the sole of the cloth. To make the seed coat slightly worn, then use 38 °C internal temperature blister species more than 24 hours (in the meantime change the water several times) to pick up, and then the seeds with coarse cloth wrapped in a warm place, until the seeds bloated, slightly dry Dry, so that you can sow (if not the swelling of the seeds should be selected, and then rubbed to deal with swelling). Third, nursery: According to the number of seeds, seedlings can be broadcast or pot broadcast. Seedbed soil should be loosened and the soil should be screened and sterilized on the seedbed. The simple method of disinfection is exposure, fumigation, high temperature treatment for half an hour, or use 1000 times potassium permanganate solution, and seal with a film for 24 hours, after disinfection for a few days, you can use. Spray sufficient water on the seedbed before sowing. After the water seepage, spread the seeds that were selected and treated evenly. Then cover the 1cm thick coarse sand or fine coal cinder with a mesh screen, spray the water to moisten the bed and arch The film, if the temperature is appropriate (approximately 5-15 days before emergence can occur. At this time should be based on the local temperature conditions, remove the film). When planting after May, avoid cover film to prevent burns. Seedling growth is slow, can be poured 1-2 times the amount of urinary excrement or 0.1% urea solution, after pouring, then use a fine watering can washed away foliar fertilizer solution, so as not to burn the young leaves until the seedling height of 15 cm, It can be transplanted, the plant spacing is about 70 centimeters, pots (16-26 centimeters in diameter basins) pots and one pot, larger pots can be planted 2-3 strains. The soil used is neutral, acidic, and alkaline, and requires looseness, fertility, and water. Fourth, management: pay attention to timely watering and fertilization, diligent weeds, timely drainage, prevention and treatment of a small number of aphids harm large leaves, when the seedling height 25 cm above, grow three leaves on the petiole, they can begin to watch when the temperature reaches 25 °C, especially when it is raining fine, playing a sweet song to it, it will stretch and rotate with the leaflets with the beat. The growth is strong at this time. The top bud should be removed to promote its multiple foliage. In case of high temperatures above 38°C, care should be taken to prevent shading in the hot sun. Below 0°C after autumn, the upper plant leaves are deciduous, and the roots of the upper part of the spring return to germination. Attachment: Cuttage seedlings can be selected thicker branches, cut with a small 8-10 cm section, and cut off the lower branches of each section (reserve the upper leaves), insert the base of the cuttings into the sugar water for a few minutes, then, In a pre-prepared nursery bed made of sandy (or fine cinder) paving, use a stick slightly thicker than the cuttings, and then insert the cuttings so that the depth does not exceed 1/3 of the cuttings. Finally, spray enough water, and pay attention to the seedbed insulation shading, spray fine water 4-6 times a day. After 7-10 days, you can take root. After the upper bowl, normal maintenance, viewing and sales can be performed. China Agricultural Network Editor
