Description
Technical field
The present invention relates to Rice Cropping field, more particularly to a kind of rice seed of raising varieties in saline-alkali areas Rice Cropping survival rate
Plant method.
Background technology
Chinese inland Saline-Sodic ground area occupies third place in the world, and wherein West of Songnen Plain Saline-Sodic ground area has been just
Reach 373hm2.Soda alkaline land soil reacts in strong basicity, in salinity composition based on soda (NaHCO3 and Na2CO3), soil
Earth characteristic is different from strand neutrality solonchak, and pH is more more than 8.5, heavy salinized ground soil pH>9.5, saturation extract electrical conductivity
ECe>10dS/m, sodium matter basicity ESP>50%.In severe Saline-Sodic area, the saline-alkali wasteland for having sheet is distributed, it is impossible to plant
Plant the paddy rice of not Salt And Alkali Tolerance.In West of Songnen Plain Saline-Sodic area, traditional Rice Cropping is planted in the way of flat work.
This planting patterns has in subject matter present on severe soda alkaline land：
1st, soil salt is spatially evenly distributed, and saline and alkaline degree is high, to each growth and development stage after rice transplanting
By the Saline Alkali Stress of high intensity；
2nd, the soaked field desalinization of soil by flooding or leaching needs substantial amounts of irrigation water, and the local desalinization of soil by flooding or leaching is locally evaporated brine；
3rd, put down and be chronically at waterflooding anaerobic environment as paddy rice, be unfavorable for rice tillering and grow；
4th, heavy salinized ground permeability is poor, puts down ground temperature under making long-term waterflooding low.
The content of the invention
The present invention discloses a kind of paddy rice planting method of raising varieties in saline-alkali areas Rice Cropping survival rate, solves Saline-Sodic
The low problem of regional Rice Cropping survival rate.
The present invention discloses rice ridge culture salt-avoiding water-saving planting method of severe soda saline-alkali soil technical solution, including following
Step：
(1) drainage trenching prior to seeding, is exactly to dig one around rice seedling bed to enclose zanjon, and the width of discharge conduit should be 0.7
More than rice, depth will reach 0.8 meter to 1.2 meters, and it is so deep why gutter is dug, one be for thoroughly draining in time,
Can drain then as gutter a part of salinity leaching to soil bottom, two is, for lowering of watertable, to prevent salt
Alkali is trapped in arable layer；
(2) fertilising site preparation, 2000 to 2500 kilograms of the organic fertilizer in every mu of seedling field, rice seedling bed special complex fertilizer 25 to 30
Kilogram, uniformly spread fertilizer over the fields in rice seedling bed, pteridophyte 150-210kg/ mus of fermentation, ardealite 200-280kg/ mus, ammonium chloride
50-70kg/ mus, and using rotary cultivator by the farmland rotary tillage being exposed to the sun, the modifying agent and soil for making administration are sufficiently mixed, tilling depth 10
More than centimetre, watering makes soil soak enough, soil fermented, reacted 7-10 days；
(3) agricultural chemicals is applied in salt-soda soil, using solar exposure farmland 3 days, the evil of agricultural chemicals was applied with sufficiently kill
Worm, grass crop；Salt-soda soil seedling is needed using the planting type of zanjon high bed；
(4) salt-soda soil seedling, the density of rice growing can not be too big, every square metre broadcast sowing 200 grams of seeds just can be to adopt
Be conducive to nurturing staff with the mode of this light seeding, when sowing, premature rice is uniform, after sowing, pressing gently is planted
Son, makes seed be absorbed in the mud on top layer, and this process is also referred to as steps on paddy, and stepping on paddy can play warming antifreeze, drought resisting erosion control work
With, while can also play a part of to promote rice shoot to take root, next, being stitched in the standardized bar of the centimeters of seedling bedside edge 10 with spade, use
To be compacted mulch film, the overlay film on the rice seedling bed of moistening, it is possible to increase ground temperature, moreover it is possible to increase the humidity in rice seedling bed,
(5) divide different times carries out water-saving culture, specific method to paddy rice：
1) in period of seedling establishment, control water layer keeps 3~4cm water layers before 3-4cm, period of seedling establishment to early tillering stage；
2) in tillering stage, control water layer keeps 1.5cm water layers in 1.5cm, early tillering stage to boot stage；
3) at heading stage, maintain water layer in 3cm, heading stage maintains 3cm water layers；
4) wet using dry dry and wet in the watery stage, the irrigation method based on wet fills a shallow water, pours within 3-4 days dry naturally,
Moistening 3-4 days, then upper new water, pour water for one day than conventional rice plantation extension.
Fermentation pteridophyte described in step (2) obtains by the following method：To pluck to pteridophyte that to be cut into 2-4cm long,
It is put into fermentation vat, the maceration extract stack retting for being inoculated with cellulolytic enzyme is put into pond, maceration extract submergence stirred one every 4 days
It is secondary, after 30~40 days, pteridophyte is cleared, dry, crush, obtain the pteridophyte of fermentation.
The positive effect of the present invention is：It is minimum spy using the ridge waist position pH value and EC in severe Saline-Sodic area
Murder by poisoning of the salinity to rice root has been hidden in point, ridge waist position rice transplanting, has createed the environment of suitable paddy rice normal growth.Solution
Severe of having determined soda alkaline land Rice Cropping survival rate is low, problem of the growth by saline and alkaline suppression etc..With advantage of lower cost, subtract
Rake the soil level less measure, improved soil, increase ground temperature, expand effective cultivated area, increase the significance of rice yield.
Specific embodiment
The present invention is further described with reference to embodiment.
