Description
Technical field
The present invention relates to alkaline land improving technical field, specific field improves salt-soda soil soil to be a kind of by planting prairie milk vetch
The method of earth fertility.
Background technology
Salt-soda soil refers to that soil is influenceed by the factor such as natural or artificial, causes salts substances gradually to penetrate into soil
Go, so that the saliferous and alkalinity of soil are more, and cause this kind of soil not used, China salt-soda soil substantially distributed area
In northwest, northeast, North China and coastal region, salt-soda soil primarily forms work of the soil in evaporation that reason is more arid area in domain
Under, moisture is evaporated into vapor, and is emitted into air, but the salinity in water can not be excluded and stayed among soil,
By prolonged accumulation, salinity gradually increases in soil, therefore and form salt-soda soil, improvement and the utilization in salt-soda soil are always
The problem of relevant industries personnel pay attention to, prairie milk vetch is pulse family Astragalus herbaceos perennial, mainly in China northeast, northwest
Sent out with performance, prairie milk vetch root systems such as the regional plant utilization such as North China, prairie milk vetch strong stress resistance, drought resisting, cold-resistant, anti-blown sand Salt And Alkali Tolerances
Reach, for main root embedded depth up to 2~4 meters, root system amplitude raw a large amount of root nodules, nitrogen fixing capacity is strong, can improve up to 1.5~4 meters
Alkaline land soil structure, alkaline land soil fertility is effectively improved, therefore by reasonably planting prairie milk vetch in salt-soda soil, can reach
To the purpose of alkaline land soil comprehensive improvement.
The content of the invention
It is an object of the invention to provide a kind of method for improving alkaline land soil fertility by planting prairie milk vetch, to solve
The problem of being proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：It is a kind of to improve salt-soda soil soil by planting prairie milk vetch
The method of earth fertility, its method comprise the following steps：
1) fertilising site preparation：It is 2 that mass ratio is applied on salt-soda soil:1 barnyard manure and the mixture of phosphate fertilizer, amount of application 20~
26kg/ mus, are then turned over to salt-soda soil；
2) seed impurity removing：Removal of impurities processing, the rotating speed 20 of cylindrical pre-cleaning screen are carried out to prairie milk vetch seed using cylindrical pre-cleaning screen
~28r/min, except miscellaneous time is 8~15min, the prairie milk vetch seed after removal of impurities is cleaned at normal temperatures using distilled water,
Scavenging period is 10~15min, prairie milk vetch seed will be laid on shield after cleaning, and shield is positioned over into sunlight
Straight shot places are basked seeds, and prairie milk vetch seed time of exposing to sunlight is 10~16h；
3) sow：Prairie milk vetch seed described in step 2) is sowed using the seeding method of drilling, depth of planting 1~
2cm, sowing line-spacing are 0.5~1.2m, application rate 0.2~0.4kg/ mus, after sowing, town are carried out to sowing soil in the ranks
Pressure, suppression number are 1~2 time；
4) after planting manage：Once poured every 14~21 days, a weeding was carried out every 15~20 days.
Preferably, phosphate fertilizer described in step 1) is calcium superphosphate, and available phosphorus content is 12%~16%.
Preferably, the month sowed described in step 2) is May, June or July.
The beneficial effects of the invention are as follows：A kind of method for improving alkaline land soil fertility by planting prairie milk vetch, prairie milk vetch
It is a kind of legume for needing phosphorus amount more, therefore appropriate quality and yield that prairie milk vetch can be improved using phosphate fertilizer, while matting
Organic matter and various nutrients are rich in fertilizer, the content of organic matter in alkaline land soil can be increased, both, which combine administration, to be
Prairie milk vetch seed provides good growing environment, and turning over makes moisture in alkaline land soil, nutrient, air and heat etc. more uniform
Coordinate, be advantageous to increase soil fertility, good condition is provided for sowing；Prairie milk vetch seed is carried out by using cylindrical pre-cleaning screen
Removal of impurities, dust removal rate is high, ensures the germination percentage of prairie milk vetch seed, and basking seeds, it is harmful entrained by prairie milk vetch seeds self to kill
Bacterium, disease incidence is reduced, while germination can be promoted, 5,6 or proper temperature in July, ground moistening, be advantageous to seed top
Go out soil emergence, after sowing, suppressed to sowing soil in the ranks, the big space in alkaline land soil can be reduced, made
Air volume amount reduces, and surrounds the soil density increase of prairie milk vetch seed, and prairie milk vetch seed fully contacts with soil, absorbs and support
Point, elastic appropriate environment is provided for the emergence of prairie milk vetch germination, pours 1 time daily, ground moistening is kept, every 15~20
It carries out a weeding, avoids weeds from grabbing nutrient with growing more slow prairie milk vetch seedling, influences prairie milk vetch growth of seedling；It is husky
Prosperous well developed root system is beaten, raw a large amount of root nodules, nitrogen fixing capacity is strong, can improve alkaline land soil structure, so as to effectively improve salt-soda soil
Soil fertility.
