苗木种类
Seedling species
苗木:具有根系和苗干的树苗。凡在苗圃中培育的树苗不论年龄大小，在未出圃之前，都称苗木。
Seedlings: Tree seedlings with roots and stems. All seedlings cultivated in the nursery, regardless of their age, are called seedlings before leaving the nursery.
苗木种类：实生苗、营养繁殖苗、移植苗、留床苗。
Seedling types: seedlings, vegetative propagation seedlings, transplanted seedlings, and bed seedlings.
（一）实生苗：用种子繁殖的苗木。凡以人为的方法用种子培育的苗木叫播种苗，在野外母树天然下种自生的苗木叫野生实生苗。
（1） Seedlings: Seedlings propagated from seeds. Seedlings cultivated with seeds through artificial methods are called sowing seedlings, while seedlings naturally grown under mother trees in the wild are called wild seedlings.
播种苗根系发达，苗木生长整齐、健壮、质量好。野生实生苗密度不匀，分化严重，根系不发达。
The root system of the seeded seedlings is developed, and the seedlings grow neatly, robustly, and of good quality. The density of wild seedlings is uneven, with severe differentiation and underdeveloped roots.
（二）营养繁殖苗：根据所用的育苗材料和具体方法又可分为:
（2） Nutritional breeding seedlings: They can be further divided into:
1、插条苗：用苗干或截取树木的枝条扦插育成的苗木。
1. Cuttings: Seedlings grown by cutting the stem or cut branches of a tree.
2、埋条苗：用苗干或种条，全条横埋于育苗圃地育成的苗木。
2. Buried seedlings: Seedlings grown by burying the entire stem or seed strip horizontally in the nursery.
3、插根苗：用树木或苗木的根，插入或埋入圃地培育的苗木。
3. Rooted seedlings: Seedlings cultivated by inserting or burying the roots of trees or seedlings into the nursery.
4、根蘖苗：又叫留根苗，是利用地下的根系萌出新条育成的苗木。
4. Root tiller seedlings: also known as root retention seedlings, are seedlings grown by sprouting new shoots from underground roots.
5、嫁接苗：用嫁接方法育成的苗木。
5. Grafted seedlings: Seedlings raised by grafting methods.
6、压条苗：把不脱离母体的枝条埋入土中，或在空中包以湿润物，待生根后切离母体而育成的苗木。
6. Layered seedlings: Seedlings grown by burying branches that do not detach from the mother plant into the soil or wrapping them with moist material in the air, and cutting them off from the mother plant after rooting.
7、组培苗：利用母体上的组粪池模具 路缘石模具 唐山通风管道 塑钢电缆挂钩 钢纤维 钢制拍门 植绒机 铜雕佛像织或细胞在营养液中育成的苗木。
7. Tissue culture seedlings: Seedlings grown in nutrient solution using tissues or cells from the mother body.
三、留床苗：在上年的育苗地继续培育的苗木。
3、 Bed seedlings: Seedlings that have been continuously cultivated in the previous year's nursery.
四、移植苗：上述各种苗木，凡在苗圃中把苗木移栽到另一块苗床（地段）继续培育的苗木叫移植苗。
4、 Transplanted seedlings: The various seedlings mentioned above, which are transplanted to another seedbed (plot) in the nursery for further cultivation, are called transplanted seedlings.
