摘要
沙阳奶香是三明市农业科学研究院选育的全缘琴叶榕优良新品种,2023 年获国家林草局植物新品种保护授权,品种权号为 20230699.为进一步提高该品种的种植效益,探讨了不同植物生长调节剂对沙阳奶香扦插成活率的影响,以及密度和修剪措施对其根产量的影响.结果表明:高浓度的双吉尔有利于提高沙阳奶香扦插成活率,低和高浓度的吲丁·萘乙酸都能显著提高沙阳奶香的扦插成活率,较低浓度的萘乙酸和根盼有利于提高沙阳奶香扦插成活率,但较高浓度的萘乙酸和根盼会显著降低沙阳奶香的扦插成活率;4 种浓度的吲丁·萘乙酸对沙阳奶香扦插苗地上部生长均具有一定的促进作用,当浓度为 1 g·L-1 时,新梢长度为 14.4 cm,茎粗为 2.2 mm,均显著高于对照;高密度和回缩修剪有利于提高沙阳奶香田间栽培的经济产量,且密度效应(D)>修剪效应(P),田间适宜的种植密度为 45 000 株·hm-2,或种植密度为 30 000 株·hm-2+回缩修剪.
Abstract
Shayang Naixiang is an excellent new variety of Ficus pandurata Hance var.holophylla bred by Sanming Academy of Agricultural Sciences.In 2023,it was authorized by the State Forestry and Grassland Administration for the protection of new plant varieties,with the variety right number of 20230699.In order to further improve the planting efficiency of this variety,the effects of different plant-growth regulators on the cutting survival rate of Shayang Naixiang and the effects of the density and pruning measures on its root yield were discussed.The results showed that:the high concentration of GGR was beneficial to improve the cutting survival rate of Shayang Naixiang.Both the low and high concentrations of indolebutyric and naphthylacetic acid could significantly improve the cutting survival rate of Shayang Naixiang.The lower concentrations of naphthaleneacetic acid and Genpan were beneficial to improve the cutting survival rate of Shayang Naixiang,while the higher concentrations of naphthaleneacetic acid and Genpan would significantly reduce the cutting survival rate of Shayang Naixiang.The four concentrations of indolebutyric and naphthylacetic acid had certain promoting effect on the growth of the above-ground parts of Shayang Naixiang cutting seedlings.When the concentration was 1 g·L-1,the length of new shoots was 14.4 cm and the stem diameter was 2.2 mm,which were significantly higher than those of the control group.The results showed that the high density planting and shrinkage pruning were beneficial to improve the economic yield of field cultivation of Shayang Naixiang,and the density effect(D)was greater than the pruning effect(P).The suitable planting density in the field was 45 000 plants·hm-2,or the planting density was 30 000 plants·hm-2+shrinkage pruning.
