不同品种需选择适合的造林密度。如果是大径级别的,在轮伐期内,应禁止间疏伐,以稀植为主,搭配农林间作,确保各个树木能够拥有足够受光时间。选择 6 米 ×6 米、8 米 ×8 米或 7 米 ×7 米的株行距,预定永树冠杨梅树苗接穗砧木枝条嫁接工人 福建种子100万珠间作时间大概是 5 年。同时也可按照株距 4 米、行距 10 米的形式,或小行距 3 米、大行距 20 米的形式进行种植,成材的胸径大概是 40 厘米左右,立木蓄积每公顷能够达到 180~240 立方米。如果是培育中小径级别的木材,可进一步缩短轮伐期,株行距低于 4 米 ×4 米,成才胸径 20 厘米,立木蓄积每公顷能够达到 100 立方米。栽培速生杨树的过程中,普遍存在密度偏大现象,但通过实际调查能够发现,如果种植密度过大,不但会增加费用投入,同时木材的价格低、径阶小,效益差,而大径材的培育效益相对较高。
栽植管理技术、1.栽植杨树的技术要领、杨树栽苗造林的技術要领可用“三埋两踩一提苗”来概括,具体说是:先埋1/5深(20cm)表土,然后将苗放入,再埋土至2/3深(70cm左右),踩紧实,较后埋土至地面,再次踩紧实,接着将苗往上提提,以利根系舒展,浇足水。如苗木上端稍有弯曲,可在栽植时,将不垂直地面的苗木梢部转向北面,利用杨树苗的向光性,逐步把苗木梢头调直。、2.适时灌溉、杨树对水分的要求较高,所以适时灌溉不仅能提高造林成活率,还能提高杨树的生长量。除新造幼林要立即浇水外,4~6月干旱季节,要对林地适时灌溉,以保证林木旺盛生长。
保活技术以城市绿化发展、大众对绿地建设质量要求升高为基础,大树移植成为短时间改善园林绿化生态效益、优化绿地结构与景观环境、及时满足建设工程的绿化要求的重要园林绿化手段之一1看看福建的杨梅培育经验 大树移植前保活措施为较大限度利用苗木资源,保证树木成活率,需要在移植工作前,进行合理、科学的移植前保活措施,挑选优良的苗木品种,进行一定根系的修剪处理,加强根系生命力,以保证后续的移植成活率。在移植苗木挑选方面,看看福建的杨梅培育经验应选择胸径在 30 厘米以下的非名贵苗木,往往这类苗木正处于生长发育繁茂期,移植的成活率较高、缓苗期较短。
Pingzhong Yangmei Miao wholesale Wholesale of Fujian Yangmei seedlings, Longyan Dongkui Bianshan Yangmei small cup seedlings with a height of 30 cm and a diameter of about 1 cm, Shanghang Crystal local small Yangmei taste very fragrant, Zhangzhou 1-2 year grafting of large black charcoal Yangmei small cup seedlings with a cultivation height of 30-90CM-TEL13507五40047, Ningde early maturing Yangmei suitable for planting in coastal areas. 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.
