停止促进苗木上部生长的措施。这一时期,应该严禁追速效肥,防止苗木徙长。但也可以增施磷钾肥,促使苗木木质化程度加强,形成健壮的芽孢。在这段时间里,可从9月起每隔十天至半个月用春雨1号+0.3%的磷酸二氢钾进行叶面喷施,连喷三次。或用草木灰每次每亩施4-5担,连续施两次。叶面喷硼,提高抗寒能力。从9月起每隔10天喷一次春雨1号+0.5%的硼砂液或与磷酸二氢钾混喷。连喷三次。
1, stop the measures to promote the growth of the upper part of the seedlings. During this period, we should strictly prohibit the pursuit of quick acting fertilizer and prevent seedlings from growing. However, phosphorus and potassium fertilizers can also be applied to promote the lignification of seedlings and form strong spores. In this period, from September, every ten days to half a month, we can use the potassium hydrogen phosphate 1 +0.3% of the potassium dihydrogen phosphate to spray the leaves and spray three times. Or plant ash each time 4-5 mu per mu, continuous two times. Spraying boron on the leaf surface improves the cold resistance. Starting from September, sprayed with borax solution of spring rain 1 +0.5% or mixed with potassium dihydrogen phosphate every 10 days. Three times.

2、清园管理。秋冬季要对苗圃地进行全面的清园整理,疏通并开挖排灌沟,结合整枝修剪,剪除枯枝及病虫枝,同时拔除病死株和清理圃地枯枝及杂草。加强病虫害的防治,休眠期全园用波美2-5度的石硫合剂进行全面的病虫害防治。
2, the management of the garden. In autumn and winter, it is necessary to clean up the nursery land in an all-round way, dredge and excavate the drainage ditch, combine pruning and pruning, cut off the dead branches and diseases and insect branches, and remove the dead plant and clean the litter and weeds in the nursery. We should strengthen the prevention and control of diseases and insect pests, and carry out comprehensive pest control in the whole garden during the dormant period with the mixture of 2-5 degrees of sulphur and sulphur.

3、做好防寒抗寒措施。具体措施如下:
3, do a good job of cold prevention and cold resistance. The concrete measures are as follows:

①灌水防冻。霜冻来临前夕,圃地进行灌水,能使土温不低于0℃,能保苗木不致于冻死。
(1) irrigation and antifreeze. On the eve of the frost, irrigation in the nursery area can make the soil temperature not less than 0 degrees.

②熏烟防寒。特别冷的天气,可在苗圃四周设烟堆2-3处,在气温降至0℃时点烟,并保持烟雾到日出时为止。
Fumigating smoke and preventing cold. In particularly cold weather, there are 2-3 smoke pits around the nursery. When the temperature drops to 0 degrees C, smoke is lit and the smog goes up until sunrise.

③覆盖:多用于圃地露地JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 花卉,在霜冻前,在地上覆盖干草、草席等,此法既经济效果又好,应用极为普遍。另外也可覆盖塑料薄膜等材料,但需要有一定的经济条件。
Coverage: it is mainly used for flowers in the open field, covering hay and straw mat before the frost. This method is both economical and effective, and is widely used. It can also cover plastic film and other materials, but there must be some economic conditions.
