Mix fluvial sand, will mix after thing is mixed homogeneously with original soil and soil is carried out smooth.
Further, described field planting comprises the following steps: when 5-7 sheet true leaf occurs in seedling, seedling is carried out pinching and transplants,
Smooth good plot carries out digging cave according to seeding row spacing 50cm × 50cm, deep about the 10cm in cave, footpath, cave 10-15cm, and every cave plants
Plant a strain.Water permeable after having planted immediately.
Preferably, after planting, set up sunshade net, hide 3-4 days, after slow Seedling, remove sunshade net.
Further, described maintenance management comprises the following steps: within 2-4 days, water once, and water irrigates every time;(generally,
Within 3-4 days, watering once, within during sky drought 2 days, water once, precipitation is excessive or during long-time continuing precipitation, digs trenches to drain the water away), plant
When vertical height arrives 20-30cm, plant is carried out secondary pinching, after 3 days, spray paclobutrazol, spraying concentration 400mg/L,
Consumption 0.15-0.25kg/m2, bud stage topdresses once, the potassium dihydrogen phosphate of foliage-spray mass concentration 1%, according to
0.3-0.5kg/m2Amount spray.
Beneficial effects of the present invention:
Plant flowers of sulfur chrysanthemum according to the method for the present invention, on the one hand can effectively reduce flowers of sulfur chrysanthemum vertical height, by whole strain Altitude control
At below 60cm, the lodging of plant can be greatly reduced;On the other hand the amount of blooming of individual plant can be increased, compared to general planting
Its amount of blooming increases 20%-30%, improves the landscape effect of flowers of sulfur chrysanthemum.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, but is not construed as limiting the invention.
Embodiment 1:
Downgrade by Tianjin Economic Technological Develop-ment Area Eighth Street Taida plants resource database Qian Hui garden flowers of sulfur chrysanthemum as a example by planting.This garden
Flowers of sulfur chrysanthemum downgrade and plant and carry out essentially according to following steps:
Sowing: flowers of sulfur chrysanthemum seed is immersed in the potassium permanganate solution that concentration is 0.5% sterilizing that carries out disinfection, soaks 2 hours,
By the planting seed disinfected on 200 hole dishes, substrate uses loose fertile soil, 2 seeds of every bunch planting kind,
After planting water permeable, and cover with plastic sheeting, within every 2 days, open plastic sheeting and spray water once, keep substrate to moisten,
Keep seedling rearing room temperature at about 20 DEG C.Plastic sheeting can be opened after germination.
Seedling management: after seedling cotyledon launches, moves to hole tray the illumination that the preferably local acceptance of light is suitable, controls illumination
Intensity, should not accept direct sunlight, illumination every day 2 hours, reduces water spray number of times simultaneously and watered once to every 3 days, reduces
Water supply in media content, to improve the quality in plant later stage.Removing weak Seedling after emerging 2 days, every cave retains a strain.
Wholely: carrying out digging loosening the soil in the plot (soil is light earth) of the flowers of sulfur chrysanthemum that needs to plant, digging the degree of depth is 25cm, dredge
Mellow soil, soil block in small, broken bits, remove bulk foreign material.According to 1kg/m2Mix turfy soil so that it is uniform with top layer 0-25cm soil
Mixing, carries out smooth to soil simultaneously.
Field planting: when 5-7 sheet true leaf occurs in seedling, seedling carried out pinching and transplant, in smooth good plot according to seeding row spacing
