适时适量灌水:杨树插条苗喜湿,应经常保持土壤湿润,插条后应立即灌1次透水。插穗出芽前灌1—2次水,以利侧根生长和幼苗出土。当苗木长出6—8片叶子后,可少灌水,多中耕,以利提高土温,促进根系发育。除干旱年份外,雨季一般不用灌水。及时追肥:追肥应在苗木旺盛生长时进行,即在幼苗地下部分大量生根,地上部分旺盛生长时追肥。一般在6月下旬和7月上旬分两次追施。每亩追硫酸铵30—40斤。沟施效果较好,沟深2—3厘米,追肥后立即覆土,充分灌水。弱小的三类苗应施偏肥。中耕除草:中耕除草能减少地面蒸发,保持土壤水分,改善土壤透气性,增加土温,尤其在雨水多、地温低、杂草滋生的情况下更为重要。开始时中耕深度为2—4厘
Proper amount of irrigation: Poplar cuttings hi like wet, should always keep the soil moist, cuttings should be immediately after a perfusion. Irrigation 1-2 times before bud irrigation water to facilitate lateral root growth and seedlings unearthed. When the seedlings grow 6-8 leaves, less irrigation, more farming, to facilitate the improvement of soil temperature and promote root development. In addition to the dry year, the rainy season generally do not have irrigation. Timely top-dressing: Dressing should be vigorous growth of seedlings, that is, a large number of roots in the underground part of the seedlings, the ground part of the strong growth of top dressing. Generally in late June and early July divided into two top-ups. 30-40 kg of ammonium sulfate per acre. Ditch facilities better, ditch deep 2-3 cm, topdressing immediately after the top dressing, full irrigation. Weak three types of seedlings should be partial fertilizer. Cultivation and weeding: Plowing and weeding can reduce ground evaporation, maintain soil moisture, improve soil permeability, and increase soil temperature, which is even more important especially in rainy days, low ground temperatures and weeds breeding. Beginning cultivation depth of 2-4%
