Seedling method for improving emergence rate of malus toringoides seeds

Abstract

The invention discloses a seedling raising method for increasing the germination rate of crabapple seeds. When the fruit of crabapple becomes red or dark red, the fruit of crabapple is collected, and the plump seeds obtained from the fruit of crabapple are placed indoors to dry in the shade. And put it into a sack and store it in a ventilated place; use low-temperature stratification treatment to complete the post-ripening of the embryo; carry out 1 deep plowing in the selected nursery field in the previous winter, and use it as the center with a width of 120cm, a height of 10cm, and a step width of about 25cm. Slightly raised seedbed; loosen the soil in late March of the second year, apply compound fertilizer as base fertilizer, and disinfect the soil; use artificial sowing to sow, cover with humus soil, water once, and build a plastic shed for heat preservation and moisturizing coverage ; Keep the seedbed moist after sowing, and remove the plastic film in time when the young shoots dig into the soil. When the seedlings grow to 4-6 true leaves, the seedlings are fixed at a distance of 8-10 cm; It is easy to implement, reduces the amount of seeds used and the cost of raising seedlings is low, the emergence rate of seeds reaches more than 60%, and the growth of seedlings is more robust.

Description

technical field [0001] The invention belongs to the technical field of plant seed propagation, and in particular relates to a seedling raising method for improving the emergence rate of Begonia jellyfish seeds. Background technique [0002] Variegated Begonia, a plant belonging to the Rosaceae Apple genus Longdong Begonia, is mainly distributed in the southeastern margin of the Qinghai-Tibet Plateau. The leaves of this tree species are rich in various nutrients and have the effect of reducing "three highs". [0003] Begonia variegata is mainly used for sowing and raising seedlings. It was published in the article "Practical Technology of Forestry" (2006, (9): 31-32) "Technology for Seedling Cultivation and Afforestation of Begonia variegata". Soak seeds in warm water for germination treatment before sowing, and then adopt conventional sowing and seedling raising methods, and the seeding rate is 20-25kg / 667m 2 , the seedling yield is 65,000 to 70,000 plants / 667m 2 , but th...
