不同品種需選擇適合的（de）造林密度（dù）。如果是大徑（jìng）級別的，在輪伐期內，應（yīng）禁止間疏伐，以稀植為主，搭配農林間作，確保各個樹木能夠擁（yōng）有足夠受（shòu）光（guāng）時間。選擇 6 米 ×6 米、8 米 ×8 米或（huò） 7 米 ×7 米（mǐ）的（de）株（zhū）行距（jù），預定永樹冠楊梅樹苗接穗（suì）砧木枝條嫁接工人 福建種子100萬珠間作時間大概是 5 年。同時也（yě）可（kě）按照株距 4 米、行距 10 米的形式，或（huò）小（xiǎo）行距 3 米、大行距（jù） 20 米的形式（shì）進行（háng）種植，成材的胸徑大概是 40 厘米左右，立木蓄積每公頃能夠達到 180～240 立方米（mǐ）。如果是培育中小徑級別的木材，可（kě）進（jìn）一步縮（suō）短輪伐期，株行距（jù）低於 4 米 ×4 米，成（chéng）才胸徑 20 厘米（mǐ），立木（mù）蓄積每公頃能（néng）夠達到 100 立方米。栽培速生楊樹的過程中，普遍存在密度偏大現象，但通過實際調查能夠發現，如果種植密度過大，不但會增加費用投入，同（tóng）時木材的價格低、徑階小，效益差（chà），而大徑材的培育（yù）效益相對較高。

The survival rate of Yangmei small cup seedlings is extremely high, with a height of 40-60 cm. Over a year, 400000 seedlings are urgently shipped, with good varieties and quality, The price can be negotiated, such as one-time shipment, Fuzhou late maturing and early maturing Yangmei seedlings with a diameter of 3-5 centimeters, a weight of about 30-50 centimeters when it rains, reaching about 60-90 kilograms. Various small cup shaped Yangmei seedlings in Zhangzhou are generally picked up at 30 centimeters, Zhangpu Heigaofeng, Longhai Dongkui, Sanming pure white crystal, Nanping soft silk Yangmei seedlings, and Putian hard silk early maturing seedlings. The price generally depends on the quantity and specifications, which are included in the package, The following are reference prices: 5 yuan per bead, 8 yuan per bead, 6 yuan per bead, 19 yuan per bead, 29 yuan per bead, and 39 yuan per bead.
Cup Seedling Density Management Different varieties need to choose suitable afforestation densities. If it is at the major diameter level, thinning should be prohibited during the rotation period, with sparse planting as the main approach, and intercropping with agriculture and forestry should be carried out to ensure that each tree has sufficient light exposure time. Select 6 meters × 6 meters, 8 meters × 8 meters or 7 meters × A spacing of 7 meters between plants and rows, with an intercropping time of approximately 5 years. At the same time, planting can also be carried out in the form of plant spacing of 4 meters and row spacing of 10 meters, or in the form of small row spacing of 3 meters and large row spacing of 20 meters. The diameter at breast height of the finished wood is about 40 centimeters, and the standing wood volume can reach 180-240 cubic meters per hectare. If cultivating medium to small diameter grade wood, the rotation period can be further shortened, and the spacing between plants and rows is less than 4 meters × 4 meters, with a DBH of 20 centimeters and a standing timber volume of up to 100 cubic meters per hectare. In the process of cultivating fast-growing poplar trees, there is a common phenomenon of high density. However, through actual investigation, it can be found that if the planting density is too high, not only will it increase the cost input, but also the price of wood is low, the diameter step is small, and the benefits are poor, while the cultivation benefits of large diameter wood are relatively high.
Planting management techniques, 1. Technical essentials for planting poplar trees, and afforestation of poplar seedlings can be summarized as "three buries, two steps, and one lifting". Specifically, it is: first bury 1/5 depth (20cm) of topsoil, then put the seedlings in, then bury the soil to 2/3 depth (about 70cm), step firmly, and finally bury the soil to the ground, step firmly again, and then lift the seedlings up to facilitate the root system to stretch and water well. If the upper end of the seedling is slightly curved, the tip of the seedling that is not perpendicular to the ground can be turned to the north during planting, and the phototropism of the poplar seedling can be utilized to gradually straighten the tip of the seedling 2. Timely irrigation and poplar trees have high water requirements, so timely irrigation can not only improve the survival rate of afforestation, but also increase the growth of poplar trees. In addition to watering newly planted young forests immediately, during the dry season from April to June, it is necessary to irrigate the forest in a timely manner to ensure the vigorous growth of the trees.
The survival technology is based on the development of urban greening and the increasing demand of the public for the quality of green space construction. Transplantation of large trees has become one of the important methods for improving the ecological benefits of garden greening in a short period of time, optimizing the green space structure and landscape environment, and timely meeting the greening requirements of construction projects. Looking at the cultivation experience of Yangmei in Fujian, the survival measures before transplanting large trees are to maximize the utilization of seedling resources and ensure the survival rate of trees, It is necessary to take reasonable and scientific pre transplant survival measures before transplantation work, select excellent seedling varieties, carry out certain root pruning treatment, strengthen root vitality, and ensure the survival rate of subsequent transplantation. In terms of selecting transplant seedlings, based on the cultivation experience of Yangmei in Fujian, non precious seedlings with a diameter at breast height of less than 30 centimeters should be selected. Often, these seedlings are in a period of vigorous growth and development, with a higher survival rate and a shorter slow seedling period for transplantation.
