Planting steps
a ) presowing ready
1 . nursery pots
nursery recommended use acupuncture point basin or nursery pots nursery , don't sow directly in the field . sow directly in the field , red chose , geotemperature lower , moisture and humidity uppity , influence gemmiparous rate . apertural basin nursery also emp gemmiparous rate .
2 . seedling
seedling requirement of loose soil , breathable , fertilizer conserving , clean none disease , fertility comparatively good . commonly used groundmass have peaty soil , coco peat , pearl rock roseite , , general mix . such as peaty soil 85% + pearl rock 10% + roseite 5% . peat not too fine , pearl rock granule diameter 3 - 4 mm , roseite granule diameter 3 - 5 mm . groundmass can add the appropriate some saharansahara . most in ph value for 5.5 - 5.8 groundmass on all good germination , salvia but , geranium , shukui and pavaner grass , ph value need 6.2 - 6.5 .
3 . mounted basin
groundmass the well dress , groundmass in the dress process no need compaction , gently leveling huaidan , otherwise will change groundmass physical properties of , make the stroma breathable 's reduced
4 . watering
nozzle with fine doused water revealed at , drop of sizes to impacting surface , keep the surface for unkissed watering and antifungal one times medicament irrigates , commonly used is chlorthalonil pharmacy .
5 . presoaking
proper soaking of can hastening germination , improve gemmiparous rate . kinds of soft skin thin available cold water soaking , is thicker available warm water or hot water soaking , tiny seed can don't soaking . such as peavine black eyed susan , pre soaking can improve the germination night rate , sprout faster .
second ) , seeding
1 . densities
apertural basin sowed according to the actual case sowing 1 or cristaldo . nursery pots seeding , general type per square meter can 1 - 2 sowing seeds . according to the first nursery pots sowing in the area of seed uniform portion out , each quolified .
2 . seeding
the larger of seeds srawberries be well in matrix on , drill or , smaller seeds such as petunia , snapdragon , can be used to clean sand the well reseeding . special large seeds such as peavine , sowbread , can be on demand .
3 . sowing seeds and earth-cover depth
sowing and depth of seeds size and seeds germination 's light of . general seeds the depth of sowing seed diameter 2 - 3 unerringness . some type such as petunia , xia jin , stars flower heji , , germination light , do not need to enclothe groundmass , clothes on the surface . some type need slight covered , such as scarlet sage , snapdragon , . some seeds cover should shaohou some , evenly deep , such as ornamental millet . recommended covering materials for coarse vermiculite , it water retention and breathable are good .
4 . water spray
sow before or after covering , reoccupy fine spray nozzle with a water , soak , make seed with the stroma and enclothe materials sufficiently contact .
5 . cover
seeding in pots upper cover on glass , mulching film or plastic membrane , can keep air humidity , winter also can insulation calescence . summer unfrench epiphragm , epiphragm also can't seal , both sides must manipulatedchocolate .
6 . shade-giving
If the summer the sowing , be sure to shade-giving , otherwise too strong illumination , water evaporates copiousness , 'll effects of the seeds aitchison .
three , ) sow before management
1 . temperature
specific type according to the requirements of the undesignated temperature , most seeds 's germination temperature in 20 - 25 . temperature too high and low directly influence seeds .
2 . humidity
sow before the moisture content management is very important . nursery winter the night the soil temperature low when , weight loss less , therefore don't need in the seedling moisturizing or moisturizing . if soil temperature in the higher , in the seedling should be according to demand spray moisturizing . nursery summer when , water evaporates special fast , must be according to the actual any . if seeds very thin , to prevent the scouring , can be used immersion basin method of moisturizing .
3 . light
in addition to individual type like sowbread germination in need when the dark outside , most seeds under light . beneficial to germination seeds germinate must accept illumination , this will make the seedling spindling .
4 . undrape go covering
seeds the germinative after , to undrape timely coverage organasiamorganisms . have 60% - 70% 's seeds cotyledons in commenced should membrane peeled , seedling spindling lest . still at the same time to keep groundmass humidity , thereby not part seed germination cotyledons from seed hull of success .
5 . transplant
germchit growth to suitable for transplanting , to timely provisonal planting or out-planting , easy to create germchit otherwise lauding production delay a lethargy . various germchit transplant time not the same , according to the actual conditions on the
fixed
