不同栽培方式下的浇水注意事项

Attention under different cultivation way of watering 

　　1、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。通过合理浇水使床面保持湿润，防止小苗失水，还可调节地表温度，防止日灼。一般要求浇水次数多，每次浇水量要少。

1, try to avoid after seeding seedlings topsoil is dry, 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 water bed face moist, prevent rootstocks water loss, also can adjust the surface temperature, prevent burning. Water more general requirements, water quantity is less every time. 

　　2、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，及时浇水是关键。在北方，气候干燥季节更应注意。

Article 2, cutting, layering, buried the shoot begins to take root, sprout all need larger water, especially in the first exhibition of leaf and root (i.e., false current) phase has not yet been fully, leaf transpiration and soil water supply is less, once water will cause the plants died, water is the key in a timely manner. In the north, more attention should be paid to climate dry season. 

　　3、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浇水三四次，浇水量要大些，间隔时间也不能太长。

3, points strains seedling transplant seedlings, the seedlings in plant root system due to a knee, nursery stock within an imbalance of water supply, water supply must be strengthened. After points strains and transplant should be watered three or four times in a row, water quantity is bigger, interval time not too long. 

　　4、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。干旱天气必须浇水时也要注意。

4, 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. 

　　5、大苗除非在干旱季节才需浇水。如果水分过多，还会使苗木抗性降低，影响生长发育。

5, went to will only need water during the dry season. If too much water, still can make seedling resistance is reduced, affect the growth and development.
