And a second step of: sowing: preparing sand beds with the height of 20cm (the width of the sand beds is 1-1.5m is preferable, later seedling taking is convenient), or canvas seedling bags with the width of 15cm multiplied by 18cm, taking garden soil, loading, spraying 0.1-0.3% potassium permanganate to disinfect the soil, placing the sand beds on ridges with good drainage (the height of the ridges is 20 cm) or flat gentle slope zones which are prepared in advance, and taking seedlings when later seedling transplanting is convenient, wherein 1-1.5m is preferable.
And a third step of: the cleaning seeds are sowed in seedling bags (1 bag) or on sand beds (1 cm/grain interval), and the seeds are only needed to be lightly buried in soil or the sand beds during sowing, and the surface is covered with 1-2cm of soil or sand. The seedling raising bags are placed next to each other after sowing, and are placed neatly, so that the seedling raising bags are covered by a shading net with 70-80% shading degree after sowing, sand beds or sowing soil are kept moist but no water is accumulated, and water is sprayed for 2 times in the morning and evening in rainy days. During this period, the weed removal from the nursery bag and nursery was noted.
Fourth step: and (3) transplanting seedlings once: if the seedlings are grown by sand beds, after sowing for about 2 months, when the seedling height is more than 25cm, a short wood rod is inserted into a position of 0.5cm near the seedling, the seedlings are gently dug out, and classified according to the seedling height, wherein the grade is 1 above 25cm, the grade is 1 between 20 and 25cm, and the grade is 1 below 20 cm. Immediately after the seedling is taken from the seedbed, slurry seedling is adopted, so that the root system does not lose moisture, the root system is sealed by a plastic bag after the slurry seedling is taken, the moisture of the root system is guaranteed not to evaporate, and the survival rate is guaranteed. If the root system loses moisture and dries, seedling planting is carried out again, so that the seedlings are easy to die. And (3) leveling the ground in advance, placing prepared root controllers of 40cm multiplied by 30cm according to plant row spacing of 1.5m multiplied by 1.5m, backfilling surface soil to 1/3 of the root controllers, putting seedlings, continuously backfilling the surface soil to 4/5 of the root controllers, compacting in a layered manner, covering the surface with humus covering until the root controllers are full, and spraying out fixed root water.
If the seedling is cultivated by a seedling cultivation bag, in the 3-4 month flat land of the next year, a prepared root controller of 40cm multiplied by 30cm is placed according to the plant row spacing of 1.5m multiplied by 1.5m, surface soil is backfilled to 1/3 of the root controller, the seedling cultivation bag is taken, the seedling cultivation bag is lightly placed in the root controller, the seedling cultivation bag is gently sheared, the soil in the seedling cultivation bag is ensured not to be loose, 4/5 of the surface soil is backfilled to the root controller, the surface soil is compacted in a layered manner, and the surface is covered with a humus covering until the root controller is full, and the root setting water is sprayed.
Fifth step: and (3) managing after transplanting: and after transplanting, cleaning weeds in the root controller in time, and cleaning nursery weeds by adopting a conventional herbicide. The soil is kept moist after transplanting, watering is carried out for 1-2 times per day according to weather conditions, fertilizer is applied after new buds grow out, fertilizer is applied according to growth conditions, the fertilizer is applied to the surface of a covering, the compound fertilizer is applied for 1 time every 20-30 days after the first additional fertilizer, the rice diameter is less than 2cm, the fertilizer application amount is 25 g/plant each time, the rice diameter is more than 2cm, the fertilizer application amount is 50 g/plant each time, the organic fertilizer is applied for 1 time every 3-4 months, the fertilizer application amount is 500 g/plant each time, and the fertilizer is applied to the surface of the covering. Before the diameter of the seedling reaches 4cm, the lateral buds of the seedling are erased in time from 1.8-2m to the trunk, buds are not erased any more, and branches of the trunk below 1.8-2m are prevented from affecting the smooth attractiveness of the trunk. And culturing the seedlings to the diameter of 4cm for the second time.
And (3) secondary seedling transplanting: transplanting seedlings on the original seedling cultivation ground according to interlaced spacing, enabling plant-line spacing of the rest seedlings to reach 3m & ltx & gt 3m, taking the removed seedlings again, planting the removed seedlings in a flat space according to the plant-line spacing to reach 3m & ltx & gt 3m, replacing a root controller with a spacing of 60cm & ltx & gt 50cm, backfilling surface soil to 4/5 of the new root controller, and covering humus covering until the root controller is full.
Sixth step: and after transplanting, cleaning weeds in the root controller in time, and cleaning nursery weeds by adopting a conventional herbicide. And water is sprayed for 1-2 times/day according to weather conditions after transplanting. The reserved seedlings are subjected to compound fertilizer dressing for 1 time every 20d-30d, the fertilizing amount is 100 g/plant, the organic fertilizer is applied for 1 time every 3-4 months, the fertilizing amount is 1 kg/plant, the seedlings can be sprayed to trunks in the weather after being fertilized on the soil layer surface, and the seedlings can be transplanted out of the nursery after the rice diameter is more than 7 cm.
The traditional method comprises the following cultivation steps: sowing seeds in the lower land, transplanting seedlings to a small seedling bag, cultivating to 45-55cm high, planting seedlings in the lower land of 45-55cm high, transplanting rice with a diameter of 2-3cm, transplanting the seedlings to a plant row spacing of 1.8m multiplied by 1.8m, cultivating the seedlings in a tree planting bag with a diameter of 6-7cm or directly cultivating the seedlings to a diameter of 8-10cm, and outplanting the seedlings.
