the application of the above-mentioned carbonate type saline-alkali land soil conditioner of embodiment 5 in hybrid giant napier plantation
(1) soil is selected
Severe carbonate salts alkaline earth in genus, contain soda in 0.55-0.62 milligramequivalent in the soluble salt composition of 100 grams of soil, soil pH 8.8-9.0, the soil of saltiness 1.2-1.5% in soil, soil total gap rate is 21.3-22.3%, and the soil weight is 1.6g/cm
3.
(2) soil improvement
Per hectare saltings applies 10000 kilograms of modifying agents, after soil surface is evenly used, rotary tillage bury 20 centimeters with soil Homogeneous phase mixing, irrigate after using soil improvement agent.
(3) seedling process
To the sound seedling that germinates, be stained with plant ash in incision, or with 2% lime bubble 30 minutes, carry out antisepsis and sterilization.
(4) plant joint to prepare
Select the ripe plant at 6 monthly ages more than, choosing health, saving for planting without the stem stalk of disease and pest, first tear the blade of parcel axillalry bud off, be cut into segment by knife, the section face of the edge of a knife should be inclined-plane, every section retains a joint, each joint should there is an axillalry bud, eye top is stayed short, and length is stayed in bottom, for improving surviving rate, available ABT root-inducing powder 100ppm soaks bar 28 hours (1 gram of root-inducing powder can process stipes 3000-5000 strain), then carry out corrosion-proof and sterilization process to otch, the kind joint be cut into the same day is just sowed, in time in case loss of water.
(5) nursery
Generally carry out nursery in 2 ~ May comparatively suitable, but nursery of preferably sowing when temperature reached more than 15 DEG C in 3 months; When temperature is lower, also can shed covered with plastic film insulation nursery, can in the whenever nursery whole year.
To water every day maintenance ground moistening at nursery stage, after sowing, about 7-10 days starts to emerge, if cause native top layer to harden because watering, impact is emerged, is grown, and easily should plant joint soil layer around in time, in good time weeding, (20-30 days) desirable transplantation of seedlings when seedling grows tall 20-25 centimetre, there is phenomenon of necessarily tillering seedling stage, for expanding cultivated area, the strain of tillering node mark can be transplanted.
(6) saltings is transplanted
Planting density is mu 2000-3000 strain, and seeding row spacing is 50 × 66 centimetres or 33 × 66 centimetres; Hybrid giant napier until seedling is turned green, all will adhere to moisturizing of watering after transplanting, and to the place of the scarce root and stem of certain plants of being short of seedling, need transplant seedlings in time to mend and plant, and ensures that surviving rate is more than 98%.
(7) intertill and clean tillage
Hybrid giant napier early growth is comparatively slow, easily by the impact of weeds, should carry out 1 ~ 2 intertill and clean tillage before plant seals ridge, for the first time intertill and clean tillage, should in plantation after 1 month, and hybrid giant napier starts to sprout sprouting, selects fine day or cloudy day to carry out weeding and loosens the soil; Second time weeding should be carried out after plantation 2 first quarter moons, is at this moment the period that hybrid giant napier growth is the most vigorous, should carries out intertill and clean tillage in time after each plant harvesting, with chessom, reduce Weed infestation and regeneration, it should be noted, intertill and clean tillage can not injure root and the stem of plant.
(8) salt water fresh water rotation flow
Saltings will be watered sufficient normal root water, guarantee ground moistening, urge seedling with normal root after being transplanted, and becomes a fine day arid if meet, and needs within 2 days, to water 1 time, until could alleviate when seedling turns green grass or young crops.
