盆栽葡萄由于营养面积受到限制,根系盘结,树冠比较难控。要培育出好的植株形态,必须采取以下技术措施。换盆、换土、修根。随着盆栽葡萄植株日益长大,根系也逐渐布满盆内,延伸根沿盆壁转圈生长,形成密密的根圈。这时必须及时换盆、修根、换土。换盆就是由小盆换大盆,以增加容器体积,多容纳盆土。一般在收果后至翌年早春萌发前均可进行。换盆时先将竹片顺盆内壁插入盆底转一圈,造成盆内土团与盆壁有间隙,再将盆倒置,用手托住葡萄苗和土团。倒出后,用小刀削去土团外层约3厘米厚的旧盆土,剪除部分老根。新盆经过清水浸泡后,在盆底排水孔上盖一瓦片,施入基肥,更换部分培养土。然后把葡萄植株连土团一起装入新盆。在盆四周填入新的培养土,边填边压,使上与根群密接。最后浇一次透水。
Potted grapes due to limited nutrient area, root system, crown more difficult to control. To cultivate a good plant morphology, we must take the following technical measures. Change basin, soil, root repair. With the growing potted grape plants, the root system also gradually covered the basin, extending roots along the pelvic wall growth, the formation of dense root circle. At this time must be timely basin, root repair, soil replacement. Change the basin is replaced by a small bowl of large basin to increase the volume of the container, accommodate more basin soil. Generally in the fruit after the harvest to early spring the following year germination can be carried out. When changing the basin, insert the bamboo into the basin at the bottom of the basin and turn it into a circle, resulting in a gap between the soil and the basin wall. Then invert the basin and hold the grape seedling and the soil mass with your hands. After pouring, use a knife to cut the outer layer of soil about 3 cm thick old basin earth, cut off part of the root. After the new pot soaked in water, draining holes in the pelvic floor cover a tile, applied to the basal fertilizer, replace part of the culture soil. Then put the grape plants together with soil into the new basin. Fill the pots around the new culture soil, while filling the pressure, the upper and root groups close. Last pouring water once.
