Abstract
The invention discloses a method for interlayer seedling cultivation on a rice seedbed in a cold region. The method comprises the following steps: before seedling cultivation, paving mechanically-crushed crop straws and rice husks which are 15-20 cm in thickness on the seedbed, fermenting by utilizing an EM active liquid to form an isolated warming layer and performing wobble-plate seedling cultivation on the seedbed. According to the method disclosed by the invention, aiming at the problems of low temperature during the rice seedling cultivation in the cold region, poor seed seedling emergence, irregular seedling emergence and the like, the mechanically-crushed crop straws and rice husks are paved on the seedbed; the isolated warming layer is formed by utilizing the EM active liquid formed by various microorganisms belonging to three floras like photosynthetic bacteria, lactic acid bacteria and saccharomycetes, so that the seedbed soil temperature is improved; as the wobble-plate seedling cultivation is performed on the seedbed, the problem of poor seed seedling emergence caused by low soil temperature during seedling cultivation is favorably solved, and the normal growth and development of seedlings is ensured; an isolation layer after fermentation can also be taken as a rice compost for field production, so that the application of chemical fertilizers can be reduced.
Description
Technical field
The invention belongs to raising rice seedlings field, particularly relate to a kind of paddy rice in cold region seedbed interlayer seedling
Method.
Background technology
Improve seeding ratio, rationally cultivate the key that strong seedling is transplanting development.China at present
Rice mechanical transplanting seedling is primarily present that seedling planting amount is big, seed sprouting is poor, it is irregular to emerge,
The problem such as seedling age elasticity is little and seedling quality is poor.The paddy rice in cold region such as Heilungkiang, China northeast, Jilin,
Relative to other rice district, paddy growth has its specific condition, is firstly adapted to rice growth
Time is short, and active accumulated temperature is few, and early stage heats up slow, and mid-term, high-temperature time was short, and post drop is fast,
The features such as chilling injury is many, as Heilungkiang due to during Rice Production temperature low, growth period duration of rice
Long, substantially April is rice growing season to JIUYUE, April October to next year be leisure, air slaking,
Dry, freeze-off time, during this, most of soils is completely in frozen state, and minimum temperature reaches
-20 DEG C～-30 DEG C.Paddy rice in cold region typically starts seedling in early April, machine transplanting of rice mid-May,
The seedling phase is about at 35 days.Period outdoor temperature is sometimes less than subzero degree Celsius, although use booth
Insulation seedling, but temperature is the highest, according in recent years real to Heilungkiang build space booth internal and external temperature
Time monitoring, in average booth, temperature and the soil moisture are respectively 12 degree and 14 during raising rice seedlings
Degree, especially emerge period booth in temperature between 3-13 degree, the soil moisture 7-15 degree it
Between, it is unfavorable for seed sprouting and growth.
In order to solve, temperature during raising rice seedlings is emerged is too low to be caused seed sprouting difference and emerges the most whole
Neat problem, in paddy rice in cold region seedling, often uses three film seedling-cultivation techniques, i.e. in booth
Take Small plastic shed, and covering with plastic film on seedbed after planting, to ensure normally to emerge temperature, treat
Mulch film is taken off, owing to mulch film ventilation and penetrating light is poor, by ambient temperature and illumination effect after seed sprouting
Greatly, temperature in the shed changes difference greatly, thus it is irregular to cause existence to be emerged, simultaneously need to according to
Situation carries out artificial draft seedling exercising, and nursery is time-consuming.
Summary of the invention
It is an object of the invention to provide a kind of paddy rice in cold region seedbed interlayer method of raising seedling, it is intended to solve
The problem certainly causing seed sprouting difference during raising rice seedlings because the soil moisture is low.
The present invention is achieved in that a kind of paddy rice in cold region seedbed interlayer method of raising seedling, before seedling,
At the crop material of mechanical activation comminution and the rice husk of upper berth, seedbed 15-20cm thickness, utilize EM activity
Liquid fermentation forms isolation thermosphere, balance seedling on seedbed.
A kind of paddy rice in cold region seedbed interlayer method of raising seedling, method particularly includes:
The rice husk produced when step one, the crop material collecting field and paddy processing, dries in the air
Shine after removing moisture standby；
Step 2, select standardization rice seedling bed to do seedbed, put bedside degree 7～8 meters, build high 2.5～
2.7 meters, the steel skeleton booth of wide 6～6.7 meters, put bedside and hold gutter successfully, first 2 months of seedling
Carry out seedbed and turn over behind whole ground, with compactor, seedbed carried out smooth compacting, bottom soil
Unit weight is at 1.4g/cm3Above；
Step 3, the seedbed of smooth compacting is laid ready crop material and rice husk add
Appropriate excrement of animals, whole sealing coat laying depth about 15-20 centimetre, surrounding earth compresses
Compacting；
EM activity liquid stock solution and molasses are dissolved in water, uniformly spray by first 5 days of step 4, seedling
On the excrement of animals of sealing coat, crop material, rice husk compound, spray limit, limit is turned over, after compacting
Pressing the drought soil fine earth of 2-3 centimetre on sealing coat, surface covers one layer of mulch film；
Mulch film is thrown off before step 5, seedling balance, compacting further to sealing coat, educate by tradition
Seedling method balance on seedbed, installs Nutrition Soil, irrigates moisture content, seed soaking urged with seeding machinery
The seed that bud is good is uniformly broadcast in seedling dish.
Further, crop material first carries out mechanical activation comminution, straw length 10-15 centimetre, straw
4:1 mix homogeneously is pressed with rice husk weight ratio.
Further, EM activity liquid stock solution and molasses are dissolved in water by the part by weight of 1:1, preparation
In the aqueous solution becoming mass ratio to be 20-30%.
Further, every standard seedling dish application rate 100-120 gram, and cover 0.4～0.5 cm thick
Degree fine earth, on seed rice, irrigates moisture content.
During the present invention is directed to paddy rice in cold region seedling, temperature is low, and seed sprouting is poor and emerges irregular
Etc. problem, at crop material and the rice husk of upper berth, seedbed mechanical activation comminution, utilize photosynthetic mushroom, breast
The EM activity liquid of many genus multiple-microorganism composition of the acid big flora of mushroom, budding fungus etc. three,
Form isolation thermosphere, improve nursery soil temperature, balance seedling on this seedbed, be conducive to
The problems such as the seed sprouting difference caused because the soil moisture is low during solution seedling, it is ensured that rice shoot is normally given birth to
Long growth.Meanwhile, fermented after sealing coat be alternatively arranged as Oryza sativa L. compost, for Production of Large Fields,
Chemical fertilizer application can be reduced.
