1, like well-drained, loose and fertile sandy loam, potting culture soil can be used to rotting leaves, garden soil, fine river sand, rotting organic fertilizer each 1 part of a mixture of preparation and become.
2, the root is fine, the soil requirements are very high, should choose rich organic matter and loose soil planting. Because the ball root is small, limited storage nutrients, should be in 2-4 leaves additional phosphorus, potassium liquid fertilizer, after the net should be pulled or stand bracket, in order to prevent the collapse.
3, after the buds should be appropriate water control, in order to make the plant grow strong, before planting to early application of organic compost or coarse granular organic fertilizer, in order to improve soil fertility and soil looseness and aeration properties. The base fertilizer is mainly organic fertilizer, but the amount should not be too much, to prevent causing an increase in the concentration of salts in the soil and cause physiological disorders.
Expanded information:
The snowdrops root formation and bud differentiation need a cooler environment, the root system in the 15 ~ 18 ℃ under the conditions of the growth of the best, bud differentiation in the best in the 12 ~ 15 ℃, the growth of inflorescences to 18 ~ 20 ℃ fastest.
The root system grows best at 15 to 18 degrees Celsius.
Therefore, keep the room temperature at 15～18 ℃ at the beginning of planting; 5～7 leaves period, 12～1 5 ℃ for the induction of flower primordia, keep this temperature for 4～6 weeks, the development of inflorescence will not be reversed; and then warm up to 16～17 ℃, so that the inflorescence elongate rapidly, into the flowering period.
After the completion of flower bud differentiation appropriate prolongation of sunshine, is conducive to promoting the good development of inflorescences and early flowering, although the snowdrops like light, but also to avoid strong light exposure, in the case of too much light, higher temperatures, available shade with a transmittance rate of 70% of the shade net shade.
