Description

A kind of the Northwest heavy salinized ground alfalfa seed implantation methods
Technical field:
The invention belongs to weight grazing area Saline-alkali Field Control technical fields, and in particular to a kind of the Northwest heavy salinized ground lucerne Mu seed implantation methods.
Background technique:
China possesses about 99,130,000 hectares of saline alkali land resource, is mainly distributed on northwest China, North, Northeast China western part and east Southern riviera.China is influenced very big in addition to Qinghai-Tibet Platean by monsoon, and dry season and rainy season are obvious.Spring arid needs to fill Water, but have and fill improper without arranging or pouring water, level of ground water can be all raised, causes soil that Secondary Saline occurs, summer rainfall is concentrated, The phenomenon that easily forming waterlogging, also raising level of ground water, generate " flooded salt accompanies ".Northwest arid area, though it is to suffer from without waterlogging, Arid is more prominent, and salt accumulation in soil is very serious, arid salification, and flood, the flood supplement surface water and underground water and soil generation are saline and alkaline The root of change.
Clover (Medicago sativa) is that cultivated area is most wide in the world, one of most important Legume Forage Species, element There is the laudatory title of " King of Pasture " and " feed queen ".Whole world cultivated area is up to 33,300,000 hectares.In China, alfalfa cultivation time And northern 14 provinces and regions, especially the Northwest, the cultivated area of clover reaches 80% or so of whole cultivated areas, to locality The development of farming and animal husbandry plays an important role.Clover has blade salt discharge mechanism, and the salt tolerance in pulse family is stronger.
Heavy salinized ground soil stickiness is big, poor air permeability, and general plant can be difficult to survive by high-salt stress, and plant is basic It cannot grow.Therefore it selects halophytes appropriate to carry out artificial growth, by inhibiting surface evaporation, promotes soil salt leaching It is molten, it is the important foundation of ecology of alkali saline land reparation.Under limited cultivated land resource, rational exploitation and utilization salt-soda soil is extremely urgent, It and is the improvement cost-effective measure in salt-soda soil using salt-tolerant plant.
Summary of the invention:
The present invention provides a kind of the Northwest heavy salinized ground alfalfa seed implantation methods, using and improve clover Implantation methods can realize good ecological benefits and economic benefit, while improve heavy salinized ground soil texture, make weight The soil in grazing area can utilize again, rationally utilize resource, solve problems of the prior art.
Used technical solution is the present invention to solve above-mentioned technical problem:
A kind of the Northwest heavy salinized ground alfalfa seed implantation methods, include the following steps:
Step 1: salt-soda soil prepares:
A, salt-soda soil is chosen:
Select that the Northwest's topography is flat, the good soil of irrigation and drainage, heavy saline of the total salt content 0.6~1.2%;
B, salt-soda soil pre-processes:
Carry out Planting Medicago sativa summer the previous year, selected salt-soda soil is ploughed deeply, plough deeply depth be 30~ 35cm, shines ground 7~10 days, then is irrigated, and irrigation volume is 675~750m3/hm2;It is ploughed deeply again to autumn current year, ploughs deeply depth Degree is 25~30cm, is irrigated to winter current year, irrigation volume 900m3/hm2
Step 2: cultivating clover seedling:
A, seedling raise period:
In mid-February between late Febuary, beginning carries out the culture of clover seedling in greenhouse;
B, clover seedling is chosen:
Careless No. 13 alfalfas of kind;
C, culturing pot:
Single plant culturing pot selects circular platform type black plastic bucket, before filling culture substrate, with thimerosal to selected training Feeding alms bowl carries out disinfection;
D, culture substrate:
The Diammonium phosphate (DAP) and 0.1~0.3g of 2~2.2g is added in potting earth of the matrix based on fertile soil in matrix Carbendazim, every alms bowl averagely loads matrix 100g, and it is about 70ml/ alms bowl that water is applied before sowing;
E, it sows:
Sowing 2~4 in each culturing pot, naked seed Rhizobium Inoculation microbial inoculum prior to seeding, after planting in each culture The vermiculite of one layer of about 2cm thickness is covered on alms bowl and sufficiently watering is soaked;
F, seedling management:
Temperature control in greenhouse is at 24~30 DEG C during nursery, 16 hours or more periodicity of illuminations;
Step 3: transplanting:
A, hardening:
It is suitable before being transplanted to the indoor clover seedling of temperature highly up to 30~35cm after the growth of clover seedling is 7 weeks full Answering property is taken exercise, and opens the ventilation opening in greenhouse daily, and the indoor temperature of temperature is down to, the refining of progress 5~7 day identical as outdoor temperature Seedling;
B, plot prepares:
It before transplantation 5~7 days, will be ready to last year irrigate after plot carries out 20~15cm of rotary tillage, irrigation volume about 30m3/ hm2, plot starts to transplant, carries out seedling cave with the tool of burrowing and burrow after drying, and burrow line-spacing 80cm, spacing in the rows 60cm, hole deep 23 ~25cm;
C, it transplants:
Seedling is first cradled into 8~10cm of toothing, with transporting the transplanting of preparation to, seedling is taken from culturing pot together with matrix Out, it is put into the seedling cave accomplished fluently, seedling cave surrounding grave is good;
D, it irrigates:
The plot transplanted will be irrigated in time, irrigation volume about 750m3/hm2, slow seedling takes around 15~20 days, during which every Week irrigates primary;
E, field management:
Between the slow seedling later period, the growth of plant busy trend is kept, carries out conventional field management, periodically going to cut weeds guarantees that plant is normal Growth.
Preferably, in the step 1 in the pretreatment of salt-soda soil, summer is the Beginning of summer solar term, and autumn is the beginning of autumn solar term, described Winter is the Beginning of Winter solar term.
Preferably, it is directly 4.0cm, lower port diameter 1.5cm, height that circular platform type black plastic bucket is suitable for reading in the step 1 For 20.5cm.
Preferably, thimerosal is sodium hypochlorite in the step 2.
Preferably, the Diammonium phosphate (DAP) of 2g and the carbendazim of 0.2g is added in the step 2 mesostroma.
The present invention using the above scheme, using and improve the implantation methods of clover, can realize good ecology Benefit and economic benefit, while improving soil texture, the soil in Shi Chong grazing area can utilize again, rationally utilize resource.
