Embodiment Construction
[0016] Below in conjunction with embodiment, in saline-alkali soil peppermint planting of the present invention, tissue culture replaces interplanting method again and is described in further detail:
[0017] The present invention is specifically implemented in the yellow river delta saline-alkali production field. The normal basic salt content of the farm land surface layer is measured in advance at 0.4-0.6%, and the salt content changes significantly with seasons and drought and flood conditions. In spring, in the well-cultivated field, the peppermint of tissue culture is planted with a ridge width of 50 cm and a plant spacing of 8-10 cm. The emergence rate is 90%, and the growth process is good. The first crop was harvested in July, with an average harvest of about 450kg / mu, and the second crop was harvested in October, with an average harvest of about 250kg / mu. Winter management pays attention to moisture conservation. After the seedlings emerge in the next spring, selec...

The invention discloses a tissue re-culture replacement interplanting method in mint planting in saline-alkali soil. The method is characterized in that in the first year, selected saline-alkali resistant peppermint seedlings are planted in the saline-alkali soil field with super-wide row spacing, in the first year, strong seedlings in a growth and development period are selected and second generation field mint seedlings are cultivated by a tissue culture and rapid propagation method. The seedlings are planted in current period and join the second season harvest. Then, by the same method and procedures, tissue culture replaces outdated-matured seedlings to interplant every two years. The mint growing in the field inherits and strengthens saline-alkali resistant gene and property of the mint all the time. The continuous high yield of the mint and gradual improvement of the soil are achieved. Compared with the prior art, the tissue re-culture replacement interplanting method in mint planting in the saline-alkali soil completely eradicates yield fluctuation of a one-time reseeding and trouble of new seeding import after the yield decreases year after year because of degeneration variation of the seedlings. The continuous high yield of the field planting and the gradual improvement of the soil are guaranteed and meanwhile, the seedlings inherit and strengthen the saline-alkali resistant gene and property.
Description
[0001] 1. Technical field [0002] The invention belongs to the agricultural planting biotechnology, in particular to a method for substituting interplanting with tissue culture again in the planting of peppermint in saline-alkali land. [0003] 2. Background technology [0004] Saline-alkali land and land salinization are important problems that plague agricultural production. How to use saline-alkali land and prevent land salinization is an important subject and research object for professional and technical personnel. Years of research and experiments have found that peppermint has the important functions of saline-alkali tolerance and reducing land salinity, and has high economic value at the same time. However, the process and experience of planting peppermint in saline-alkali land found that: in the production process of peppermint in saline-alkali land, the saline-alkali tolerance ability decreases, and eventually it is difficult to avoid withering and death. The basic ...
