The invention provides a method for improving the
survival rate of young seedlings of sugarcane seedlings. The method comprises the steps that seeds are sowed in nursery boxes in a
greenhouse, when the young seedlings of the sugarcane seedlings germinate and grow to 8 mm-12 mm in height, film and gauze are lifted up
every morning, if the
water content of the
matrix volume is lower than 27%, watering is conducted, and the
water content of the
matrix volume is controlled to range from 25% to 30%; a shading net on the
greenhouse is opened, the
air humidity in the nursery boxes is controlled to be not more than 80% by utilizing
sunlight illumination; the matrix
humidity is observed every afternoon, and when the
water content of the
matrix volume is lower than 27%, the gauze and the shading net on the upper layer of the
greenhouse are put on the nursery boxes and the greenhouse respectively; the temperature of the matrix is kept to range from 22 DEG C to 36 DEG C at night till
rhizome bases of the young seedlings grow to be green from a transparent color. According to the method for improving the
survival rate of the young seedlings of the sugarcane seedlings, when the young seedlings of the sugarcane seedlings grow to the phase prone to infringing of germs, by means of covering and opening of the gauze, the film and the shading net,
water spray and illumination are combined, the temperature of the nursery boxes and the
seedling matrix are strictly controlled, the occurrences of
seedling burnt, dry
seedling and diseases are prevented, and the
survival rate of the young seedlings is improved.
