Management method after high snow wheel cutting:
Temperature : The optimum temperature for rooting of cuttings is 18 °C ~ 25 °C, below 18 °C, rooting is difficult and slow; above 25 °C, cuttings of cuttings are easily infected by pathogens and rot, and the higher the temperature, the decay The bigger the ratio. When encountering low temperature after cutting, the measures of heat preservation mainly use the film to wrap the flower pot or container used for cutting; when the temperature is too high after cutting, the measures for cooling are mainly to shade the cuttings, and to cover the sunlight 50~ 80%, at the same time, spray the cuttings, 3 to 5 times a day, the number of times of sunny days is higher, the temperature is lower, the temperature is lower, the number of sprays is less or not.
Humidity : The relative humidity of the air must be maintained at 75-85% after cutting. The humidity can be increased by spraying the cuttings, one to three times a day, the higher the temperature of the sunny day, the more the number of spraying, the lower the temperature of the rainy day, the less the number of spraying or the less. However, if it is sprayed excessively, the cuttings are easily infested by the bacteria and rot, because many kinds of germs are present in the water.
Illumination: Cutting propagation is inseparable from sunlight. However, the stronger the light, the higher the temperature in the cuttings. The more transpiration of the cuttings, the more water is consumed, which is not conducive to the survival of cuttings. Therefore, after cutting, the sun must be covered by 50-80%. After the roots grow, gradually remove the shading net: remove the shading net every day at 4:00 pm on sunny days, and cover it before 9:00 am the next day. Shading net.
Pot or transplanting : When the seedlings are filled with pots, first put a 2 to 2 cm thick coarse matrix or ceramsite at the bottom of the basin as a water filter layer, which is sprinkled with a layer of fully decomposed organic fertilizer as the base fertilizer, and the thickness is about For 1 to 2 cm, cover with a layer of substrate, about 1 to 2 cm thick, and then place the plants to separate the fertilizer from the roots to avoid burning.
The substrate for the upper basin may be selected from the following ones. Garden soil: slag = 3:1; or garden soil: medium thick river sand: sawdust (ru slag) = 4:1:2; or one of paddy soil, pond mud, humus soil. Or grass charcoal + perlite + ceramsite = 2 parts + 2 parts + 1 part; vegetable garden soil + slag = 3 parts + 1 part; grass charcoal + slag + ceramsite = 2 parts + 2 parts + 1 part; sawdust + vermiculite + Medium coarse river sand = 2 parts + 2 parts + 1 part. After the pot is finished, pour water once and place it in a slightly shaded environment for one week.
When transplanting seedlings, first dig the planting hole, and sprinkle a layer of organic fertilizer on the bottom of the planting hole as the base fertilizer (base fertilizer). The thickness is about 4-6 cm, and then cover a layer of soil and put it into the seedlings to Roots are separated to avoid burning roots. After putting in the seedlings, backfill the soil, cover the roots, and use the feet to pour the soil and pour it once.
Topping: Generally, the topping is performed twice before flowering to promote the germination of more flowering branches: after one to two weeks in the upper basin, or when the seedling height is 6 to 10 cm and there are more than six leaves, the top is removed. Keep the lower 3 to 4 leaves to promote branching. After 3 to 5 weeks of the first heart picking, or when the side branches grow to 6 to 8 cm long, the second topping is performed, that is, the top tips of the side branches are removed, and the four leaves below the side branches are retained. After two times of topping, the plant type will be more ideal and the number of flowers will be more
