The express delivery stopped immediately, and the nursery could not be sold again because of the cold and freezing weather, and it was also near the New Year, so Xiaobian was finally free again, and I could go back to the headlines and talk about some small knowledge in seedling planting. La. Old habits, less gossip, today's content is the suitable specifications for transplanting different seedlings and the choice of planting season in seedling planting.
Let's talk about the transplanting years and specifications of the seedlings. Taking the northern fruit tree seedlings sold in the Xiaobian base as an example, it can basically be divided into three intervals according to the specifications.
0.8 到 1.5 厘米的一年苗。 1. Small size, one year seedling with ground diameter of 0.8 to 1.5 cm. According to the number of customers in recent years, the most popular varieties of seedlings are still apple seedlings, peach tree seedlings, and pear tree seedlings. After all, the market for these types of fruits is the most mature, and there are many varieties. The reasonable combination of early, middle, and late ripening can be done for half a year or even half a year. There are fruits that can be harvested. The management technology of these three major varieties is relatively mature, and there are many corresponding technicians. In terms of management technology, not only medium- and large-scale planting can be performed, but farmers' planting is also no problem. The fastest increase in sales is cherry seedlings, because of the high unit price of fruit, the market demand has also increased rapidly, especially the dwarfed semi-dwarf cherry rootstocks of the Gisela series and the Landing series, the cherries grafted have risen rapidly. 0.8 到 1.5 厘米之间为佳。 For these kinds of fruit tree seedlings, I personally recommend choosing one year seedlings, and the size is preferably between 0.8 and 1.5 cm in diameter . There are two reasons. The first is that seedlings are easy to choose a specific tree shape, because the choice of tree shape is not unique, but it is selected according to the topography, soil, management method and even climate of the plantation. The saplings of this specification are basically It's all alone, you can choose the tree shape that suits you to trim. In addition, plum seedlings, walnut seedlings, hawthorn seedlings, apricot tree seedlings, and chestnut seedlings are also the most suitable seedlings of this specification; the second is the survival rate. Although the root system at the seedling stage is not as strong as the root system of the two to three year seedlings, the trunk Consumption is much smaller than large seedlings, and the proportion of root damage during transplanting is also smaller than that of the finished tree, so the survival rate is much higher. The third is low cost. Whether it is the price of seedlings or transportation costs, the price is far lower than the finished tree. At present, whether it is large-scale plantations or government procurement poverty alleviation projects, it is basically based on Xiaomiao mainly. 0.8 厘米规格以下的，地径 0.6 甚至 0.4 的，属于极小规格苗，除非是为了便宜，那么种类基本上就是地栽的花椒苗，香椿苗，以及为了嫁接用的枸橘苗和樱桃砧木了，其余的不推荐选择那么小的，近距离运输还好，远距离的话，万一包装不好容易脱水抽条，影响成活率。 One more thing, generally purchased seedlings with a ground diameter of 0.8 cm or less and a ground diameter of 0.6 or even 0.4 are very small size seedlings. Unless they are for cheap, the types are basically ground peppercorn and toon seedlings. And for the grafting of citrus seedlings and cherry rootstocks, the rest are not recommended to choose such a small size, and it is good to transport them at a short distance. In the long distance, in case of poor packaging, it is easy to dehydrate and draw, which affects the survival rate.
1.5 到 2 厘米规格树苗。 2. Saplings of medium size, ground diameter of 1.5 to 2 cm. Why did the saplings of this specification not write the age of the seedlings, because there is no way to divide the seedlings that are suitable for transplanting according to this age. 50px 以上，有些两年才可以，再一个品种也不一样，有生长快的品种，也有生长慢的品种。 The seedlings in each field are large and small. Some can reach 50px or more in one year , and some can only take two years. Another variety is not the same. There are fast-growing varieties and slow-growing ones. Variety. The most suitable seedlings of this specification are toon seedlings used in greenhouses. This specification belongs to the highest yield and cost-effectiveness of toon in greenhouses; secondly, fig seedlings, because figs grow very fast, and below this standard belong to weak seedlings; then Persimmon seedlings. As for other varieties, this does not mean that the selection of this specification is not good, but the cost-effectiveness of the seedlings of this specification is not as high as that of small-sized seedlings. After transplanting, the seedlings of the two specifications are often weaker than the small-sized ones. Species of seedlings.
3 到 5 厘米树苗。 Third, large specifications, three-year seedlings or saplings with a diameter of 3 to 5 cm. 3 到 5 厘米规格的树苗，很大程度上已经脱离了种苗的范畴，属于半成品树或者成品大树了，桃树李子等生长速度较快的果树这个规格已经进入初产期了，基本上选择大规格树苗的客户，目的无非三个，一个是常见的用于占地，作为占地苗使用；一个是少量购买，观察苗商的品种纯度；再一个就是为了更快见效益，最快速度回收成本。 In fact, saplings with a size of 3 to 5 cm have largely left the category of seedlings and belong to semi-finished or finished trees. Peach plums and other fast-growing fruit trees have entered the initial production period. Basically, customers who choose large-sized saplings have nothing more than three purposes. One is commonly used for land occupation as land-use seedlings; the other is to buy in small quantities to observe the purity of the seedlings' merchants; the other is to see benefits more quickly. Fastest cost recovery. ! 然后就是按照年限划分的蓝莓苗，三年的蓝莓苗是最适宜移栽的，第一年和第二年的幼苗成活率要相对低一些，同时养护成本也比较高，所以蓝莓苗最适宜栽植高度在 25~30 厘米高以上的三年苗。 In addition, there are also for the greening of fruit trees. The pomegranate tree of this specification is the most choice. After all, it is a green fruit tree ! Then the blueberry seedlings are divided according to the age. The three-year blueberry seedlings are the most suitable for transplanting. The survival rate of seedlings in the second year is relatively low, and the maintenance cost is relatively high. Therefore, the blueberry seedlings are most suitable for three-year seedlings with a height of 25-30 cm.
Followed by the transplanting season. I remember that I wrote an article about it before, and I would like to reiterate that the best transplanting season for most saplings is after autumn leaves and before spring. At this time, the saplings in the dormant period, whether it is damaged roots in the emergence or loss of long-distance transportation, have the lowest impact on the survival rate of transplanting. In addition, after transplanting in autumn and winter, the damaged root system of the seedling will heal and stabilize before germination. When it germinates in spring, it can enter the growth and development state faster, and its growth is better than that in spring. It should be noted that some varieties are not suitable for transplanting in winter in the northern regions with lower temperatures. One is pomegranate seedlings, persimmon seedlings, and fig seedlings. These three saplings grow fast, so the formation of xylem is slow, and it is easy to frostbite or freeze to death in winter. Fortunately, transplanting in spring. Another is Zanthoxylum seedlings. The most suitable period for transplanting Zanthoxylum seedlings is in the early stage of bud sprouting. At this time, the Zanthoxylum seedlings have the highest survival rate when transplanted. However, it is best to complete the transplantation before and after the Qingming Festival. Easy to dehydrate during transportation.
The meaning of this article is not to say that you cannot choose seedlings other than the recommended specifications, but to tell you that the selection and transplanting time of these varieties and specifications is the experience of seedling sales and management for so many years. These choices are relatively cost-effective, and under the condition of not bad money, when I didn't say good, ha!
