| 播种苗。播种后要尽量避免表土干燥，特别是在北方地区，一些小粒种子播种后覆土较浅，易受春旱的危害。通过合理灌溉使床面保持湿润，防止小苗失水，还可调节地表温度，防止日灼。一般要求灌水次数多，每次灌水量要少。 Planting seedlings. After sowing topsoil dry to avoid as far as possible, especially in the northern region, a small seed sowing after turns the soil was relatively shallow, vulnerable to the dangers of spring drought. Through reasonable irrigation make bed face moist, prevent rootstocks water loss, also can adjust the surface temperature, prevent burning. General requirements irrigation frequency, irrigation water less each time. 扦插、压条、埋条苗。这些苗的生根、发芽都需要较大水量，特别是在刚开始展叶而尚未完全生根（即假活期）阶段，叶面蒸腾量较大，土壤水分供应量较少，一旦断水就将造成植株死亡，及时灌水是关键。在北方，气候干燥季节更应注意。灌水量可适当大些，但水流要细、缓，以免水流冲力移动苗木（特别是扦插苗）。 Cutting, layering and buried. These plants take root, sprout all need larger water, especially in the first exhibition leaf and root (i.e., false current) phase has not yet been fully, leaf transpiration, soil water supply is less, once water will cause the plants died, timely irrigation is the key. In the north, more attention should be paid to climate dry season. Irrigation water can be appropriately is big, but the water carefully and slowly, in order to avoid water momentum moving seedling (especially the cuttage seedling). 分株苗、移植苗。这些苗由于在栽植时根系受伤，苗木内部的水分供应出现不平衡，必须加强供水。在分株和移植后应连续灌水三四次，灌水量要大些，间隔时间也不能太长。在灌根时可配合用青枯立克，修复受损细胞。 Plant seedlings, transplant seedlings. These seedlings in plant root system due to a knee, nursery stock within an imbalance of water supply, water supply must be strengthened. On points and transplantation should be water three or four times in a row, the irrigation water be larger, interval time not too long. When pouring the root can cooperate with withered pavlik, repair the damaged cells. 嫁接苗。嫁接苗对水分的需求不是太大，只要能保证砧木的正常生命活动即可。水不能太多，尤其是接口部位不能积水，否则会使伤口腐烂。干旱天气必须灌水时也要注意。接口部位可用溃腐灵涂抹，起到杀菌修复的作用。 Grafting. Grafting the demand for water is not too big, so long as can guarantee the normal life activities of the root stock. Water cannot too much, especially not water interface place, otherwise it will decompose the wound. Dry weather must also pay attention to the water. Interface parts available routed rotten spirit, have the effect of sterilization to repair. 大苗。除非在干旱季节才需灌水。如果水分过多，还会使苗木抗性降低，影响生长发育。 Went to. Will only need to infuse water during the dry season. If too much water, still can make seedling resistance is reduced, affect the growth and development. |
