(3) on saline land, bury root-like stock breeding
Be in the shallow ridges of 20 centimetres at above-mentioned whole good line-spacing, the root-like stock of the sandy beach root of large-flowered skullcap that tiling one section handles well of being as the criterion with spacing 15 centimetres, then covers the soil layer of one deck 2 cm thick above.
(4) manage after earthing
Carry out the middle ten days and the last ten days in March on saline land, bury the root-like stock breeding sandy beach root of large-flowered skullcap, light and temperature is not limiting factor, as long as according to weather and soil regime, irrigate seedbed in time, observe furrow surface humidity, relative moisture is 60-85%.After root-like stock germinates, ground is met personally capable person and is watered, and accomplishes to parch to irrigate, and carries out native face broken skin (loosening the soil), prevent and treat in time when finding that there is damage by disease and insect when the moistening shape of Tu Miancheng is not sticky to plot.In a word, there is not the problem of burning seedling, arid, damage by disease and insect and so in the pipe management relative poor of root-like stock nursery.
Saline land is buried the root-like stock breeding sandy beach root of large-flowered skullcap, and statistics shows that on saline land, bury the root-like stock breeding cycle (exposing native face from burying root-like stock to seedling in saline land) is 15-20 days; After 15 days, seedling Gao Keda 2cm.
Comparative example 1
According to the conventional method, directly plant after being cleaned by sandy beach root of large-flowered skullcap root-like stock, follow-up implantation methods is according to embodiment 3.
Comparative example 2
According to the method for embodiment 3, difference be in: nursery is chosen as in non-saline land.
Comparative example 3
According to the method for embodiment 3, difference be in: only to nursery adopt traditional method of turning over process.
Comparative example 4
According to the method for embodiment 3, difference be in: nursery is chosen as in the saline land of soil salt content 0.5%.
According to embodiment 1-4, comparative example's (hereinafter referred to as comparative example) 1-4 plants 1000 root-like stocks respectively, (soil salt content is all transplanted in the saline land of 0.4% to number of seedling, seedling time, planting percent and the transplanting seedling time after transplanting, management method is identical, grow the first young leaves time), survival rate (is all transplanted to soil salt content in the saline land of 0.4%, management method is identical, plants statistics after 3 months), result is as shown in the table.
| Project | Number of seedling | The seedling time | Planting percent | Transplanting seedling time | Survival rate |
| Embodiment 1 | 826 | 16 | 82.6％ | —— | 82.6％ |
| Embodiment 2 | 852 | 15 | 85.2％ | —— | 85.2％ |
