Embodiment 1
[0027] (1) In April, use river sand as the substrate and use bricks to lay a sand bed with a width of 1.2m. One week before transplanting, disinfect the sand bed with 0.5% carbendazim;
[0028] (2) Using the tissue culture seedlings of Yuncane 05-51 and Yuncane 06-407 as materials, the sugarcane tissue culture seedlings placed in the bottle were hardened for 4 days under the conditions of greenhouse, ventilation and natural light, and then the bottle was opened Cover and harden the seedlings for 2 days;
[0029] (3) Wash the sugarcane tissue cultured seedlings after seedling hardening in step (2), soak them with 0.5% carbendazim for 10 minutes, plant them on the sand bed in step (1) with a plant spacing of 3 cm and a row spacing of 5 cm, and water enough Set root water, then cover with film for 12 days, ventilate properly to prevent mildew, spread a layer of bagasse or peat soil on the sand bed after the seedlings survive, and then thinly apply compound fertilizer 2 times, if ...
Embodiment 2
[0033] (1) In August, use river sand as the substrate and use bricks to lay a sand bed with a width of 1.2m. One week before transplanting, disinfect the sand bed with 0.5% carbendazim;
[0034] (2) Using Yuncane 08-1609 tissue-cultured seedlings as materials, the sugarcane tissue-cultured seedlings placed in the bottle were hardened for 3 days in a greenhouse, ventilated, and natural light conditions, and then the bottle cap was opened for another 3 days. ;
[0035] (3) Wash the sugarcane tissue cultured seedlings after seedling hardening in step (2), soak them with 0.5% carbendazim for 10 minutes, plant them on the sand bed in step (1) with a plant spacing of 2 cm and a row spacing of 6 cm, and water enough Set root water, then cover with film for 15 days, ventilate properly to prevent mildew, if it is in summer, add a shade net, spread a layer of bagasse or peat on the sand bed after the seedlings survive, and then thinly apply compound Fertilize once, if the leaves grow t...
Embodiment 3
[0039] (1) In November, use river sand as the substrate and use bricks to lay a sand bed with a width of 1.2m. One week before transplanting, disinfect the sand bed with 0.5% carbendazim;
[0040] (2) Using Yuncane 08-2800 tissue culture seedlings as materials, the sugarcane tissue culture seedlings placed in the bottle were hardened for 4 days in a greenhouse, ventilated and natural light conditions, and then opened the bottle cap and hardened for 3 days ;
[0041] (3) Wash the sugarcane tissue cultured seedlings after seedling hardening in step (2), soak them with 0.5% carbendazim for 10 minutes, plant them on the sand bed in step (1) with a plant spacing of 3 cm and a row spacing of 6 cm, and water enough Set root water, then cover with film for 10 days, ventilate properly to prevent mildew, if it is in summer, add a shade net, after the seedlings survive, spread a layer of bagasse or peat on the sand bed, and then thinly apply compound Fertilize 2 times, if the leaves gro...
