High yield cultivation
The planting yield and planting efficiency are higher, and the average yield per mu is 1000-1250 kg. 1? Germination Seedling Choose a large bulb with good color, good shoots, and no damage. In mid-April, we used a mat to make a circle in the whole nursery field. Wet rice straw was placed in the circle. We stacked the dome buds alternately in two layers, covered with rice straw to stimulate germination, and sprinkle water every day to keep it moist. Germination was carried out until 3-4 lateral shoots were germinated. The nursery field is first put on water, and then the maggots are pressed into the mud to keep the bud heads at the same height. The spacing of the rows is 8-10 cm. Keep a shallow layer of 1.5-3 cm after sowing. 2. Soil fertigation Choose fertile loose sandy loam fields with smooth formation, drainage and irrigation, 1250 kg per hectare of composted high quality home-cooked fertilizer, 30-40 kg of ternary compound fertilizer (or 20 kg of urea plus 50 kg of superphosphate plus potassium sulphate) 20 kg) and 1.5-2 kg of zinc sulfate as base fertilizer. After fertilizing, plunge 25-30 centimeters deep and wait for use. 3? timely colonization in mid-May, in the seedlings 25-30 cm high, there are 5-6 rhizomes when the colonization. When planting, the ramets on the mother plant were cut off from the middle of the stolon, leaving the shoots and retaining 25 cm of tall phyllo-stem. The planting depth is 9-10 cm for mother plants and 12-15 cm for ramets. Spacing 40-50 cm, plant spacing 28-30 cm, 1 plant per hole or ramets 1 with 3-5 lobulated stems. About 5100 plants per acre. 4. Field Management (1) Cultivate and weed. After the live tree till the tillering stage, weeding and weeding were performed 2-3 times between the rows, once every 10 days, and the cultivating depth was 6-8 cm. (2) Moisture regulation. Wet irrigation after planting till the tillering stage, keeping the water layer 2-3 cm during the tillering period, keeping the water layer 4-6 cm during the bulb expansion period, and water cut off at the end of September and early October. (3) Reasonably chase fertilizer materials. General follow-up twice. The first time in the end of June to the beginning of July to give birth to the ramie period, the second time in the end of July and early August when the bulb began to expand, urea apply 8-12 kilograms per acre. In addition, at the end of the term of delivery, spray per acre with a solution of 0.3% urea (or urea plus potassium dihydrogen phosphate) 70-80 kg to prevent premature aging. Spray once every 10 days and spray 2-3 times. China Agricultural Network Editor
