Embodiment Construction

[0017] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with the embodiments.

[0018] The invention provides a kind of cultivation method of saline-alkali resistant poplar, comprising the following steps:

[0019] Step 1, selection of male parent and female parent: take European Alkaline Populus as male parent, mainland Xinjiang Poplar as female parent, and cut the selected male parent and female parent;

[0020] Step 2, the acquisition of hybrid progeny: the female parent and male parent after step 1 cuttings are obtained hybrid seeds by artificial control pollination, and 600 strains of hybrid progeny are bred by seeds; You can also choose 700 plants, and you can choose within the range of 500-800);

[0021] Step 3, seedling stage selection and hybrid vegetative propagation: observe the traits of 600 hybrid offspring, select 20 well-g...

Abstract

A cultivation method of high-salinity-alkalinity-resistant environment-friendly narrow-crown poplar includes following steps: step 1, selecting a male parent and a female parent: taking European alkali poplar as the male parent and mainland populus alba as the female parent, and cutting the male parent and the female parent; step 2, hybridizing to acquire a progeny selection group, testing characters like adaptability, resistance to salt and alkali, resistance to drought and flooding, resistance to cold and heat and resistance to lodging with two years, and selecting 5-15 hybrid strains; step4, performing asexual comparison testing and selecting: performing cutting propagation on the 5-15 hybrid strains, and testing the characters like adaptability, resistance to salt and alkali, resistance to drought and flooding and resistance to lodging to select salinity-alkalinity-resistant poplar. The salinity-alkalinity-resistant poplar cultivated by the novel cultivation method is formed by adopting the European alkali poplar and the mainland populus alba, has the advantages of high adaptability, high resistance to wind and drought and high growth speed, has outstanding salinity-alkalinityresistance which can reach 1.2%, and has great popularization value in afforestation in coastal mud flat and inland saline-alkaline regions of 0.6-1% in salt content.

Description

technical field [0001] The invention mainly relates to a cultivation method of severe saline-alkali environment-friendly narrow-crown poplar, belonging to the technical field of plant breeding. Background technique [0002] Poplar is the most widely distributed and most adaptable tree species in the world, and it is also one of the important fast-growing timber tree species in my country. [0003] Populus tree species are divided into 5 factions according to their morphological characteristics, geographical distribution and hybrid affinity, namely: Leuce or Poplus, Aigeiros, Tacamahaca, Leucoides, and Populus euphratica. Pai (Turanga), poplar sect is divided into poplar sub-pai and aspen sub-pai, but intraspecific variation is abundant, and there are many natural and artificial hybrids between species, which makes the genetic relationship between different poplar sects or species different, and the genetic relationship is relatively high. Close poplars are prone to hybridiz...
