What are the methods for selecting and raising sugarcane seeds?
Sugarcane tastes sweet, and what is mainly eaten is its juice, and most people quite like eating it. Many farmer friends grow sugarcane to eat, so how should sugarcane seeds be selected well? What seedling-raising methods are there? Friends who want to know, hurry and read on!
1. How are sugarcane seeds selected?
1. Choose seeds with high quality, high yield, strong disease resistance, good taste, and good adaptability, and with excellent varieties. When selecting sugarcane seeds, choose sugarcane tips that are thick and sturdy, with thick sugarcane stems, wide green leaves, uniform and without cracks, and free of pests and diseases as seed, and avoid using sugarcane tips with pests and diseases as seed.
2. Choose seeds that are plump, undamaged, and free of pests and diseases on both buds, soak them in 2% lime water or water for 1 to 2 days to achieve the effect of eliminating pests and diseases and improve the drought resistance of the sugarcane variety.
2. What seedling-raising methods are there for sugarcane seeds?
1. Greenhouse seedling raising
(1) Preparing the seedbed
For planting sugarcane, choose sandy loam land that is convenient for irrigation and drainage and sheltered from wind and facing the sun, and first water the land thoroughly, then carry out deep plowing and make beds, and after using sufficient base fertilizer, cover it with a thin layer of soil. The bed width and spacing should be determined according to the specific seedling-raising method, to facilitate later management.
(2) Treating the seed buds
Using sugarcane stems for seedling raising, generally there is no need to cut them during the seedling-raising period; wait until seedlings grow and need to be transplanted, then cut them. If during the seedling-raising process the sugarcane buds are lost rather seriously, then divide the sugarcane stems into segments of 2-3 buds, soak them in 2% quicklime water or 50% zinc ammonium acetate 400-fold solution, with a soaking time of about 10-14 hours for sprouting, and when the sprouts grow to the standard, they can be transplanted and sown.
(3) Transplanting the sugarcane seed
The whole seedlings should first be arranged neatly, with the bud positions placed flat facing sideways, and the interval between each sugarcane seed at about 2cm. After arranging and placing the sugarcane seeds neatly, to prevent rolling, fix both ends with wet soil, spray with 1% lime water, and cover with a layer of fine soil, with a thickness of about 2cm.
(4) Adjusting temperature and controlling water
The temperature needed by sugarcane during the seedling-raising period is about 20-30°C. If it is higher than 35°C, cooling measures are needed, such as uncovering the film or watering. If the temperature is lower than 15°C, keep it warm in time, and on cold nights cover with a layer of straw curtain. During the germination period of the sugarcane seed, keep the soil moist, and water in time according to the soil moisture. If the moisture content of the sugarcane stem is lower than 50%, it will affect the germination rate of the sugarcane stem.
(5) Cutting the stems and transplanting
When the sugarcane seedlings grow to the 3-5 leaf stage, begin lifting the seedlings and cutting the stems. If you want to obtain high yield, wait until the sugarcane seedlings have tillered at 6-7 leaves before cutting the stems and transplanting.
2. Plastic large arch shed seedling raising
(1) Covering with film
After sowing is done, cover with a layer of plastic film. Before covering with film, first insert long bamboo strips into the seedbed, bend the bamboo strips into an arch shape as supports, then cover with film, press the edges of the shed film tightly all around with wet soil, and cover with a layer of straw curtain on top to ensure the temperature can rise quickly and promote this, which helps raise the soil temperature and promote seed germination.
(2) Seedbed
Control the temperature inside the shed in real time. If the temperature inside the shed is higher than 35°C, it will damage the sugarcane seedlings. Methods such as watering or uncovering the film can be used; water in time, and water evenly. The phenomenon of waterlogging at the edges and drought in the middle is likely to appear in the seedbed after film covering. Not only should the amount of watering be controlled to keep the seedbed somewhat moist, but urea water can also be appropriately sprayed to promote seedlings, to prevent yellow and weak seedlings from appearing.
(3) Hardening the seedlings
In order to let sugarcane seedlings adapt to the outside environment, the film can be appropriately uncovered at noon to let the sugarcane seedlings gradually adapt. The time for hardening the seedlings is grasped after the seedlings have grown 2-3 leaves.
The above is all the content that the editor wants to share with everyone today. It will soon be time to plant sugarcane. When buying seeds, it is still very necessary for everyone to choose seeds with high quality, high yield, strong disease resistance, good taste, and good adaptability. If you do not know how to raise seedlings, you can also learn the methods above. I hope this article can help everyone.
