Abstract

The utility model provides a ferment material seedling culturing bed for rice in cold areas in the North of China, which comprises a square ground trough, ferment materials and ground surface soils. The ferment materials are uniformly paved at the lower part in the square ground trough. The ground surface soils are covered above the ferment materials in the square ground trough. The ferment material seedling culturing bed is suitable for high-yield creating cultivation of the rice in rice cropping regions in the cold areas and has the advantages that by the ferment material seedling culturing bed, the ground temperature can be raised; the ferment materials have effects of insulating coldness, preserving heat and effectively raising the grounding temperature of the seedling culturing bed; by ferment materials seedling culturing, warm bed seeding is realized, the bed temperature is raised by over 3 DEG C, the ground temperature is raised by 100 to 130 DEG C at the seeding age of 35 to 40 days; seedlings emerge much earlier by 3 to 4 days and the seedlings are cultured much earlier by 7 days to snatch the accumulated temperature by 100 DEG C, so that the accumulated temperature can be raised by 200 to 230 DEG C in the nursery period; the same variety of rice is added by 0.5 leaf under the condition of the ferment materials, the effective tillering stage is prolonged by 6 to 8 days, the effectively tillering increase is accelerated particularly in the later period of growth, and the percentage of ear bearing tillers is high; compared with the conventional cultivation, the yield is increased by over 10 percent and the yield of unhulled rice per hectare is increased by 770 kilograms.

Description

The north paddy rice in cold region ferment material bed of growing seedlings

Technical field

The utility model relates to a kind of bed of growing seedlings, and belongs to the seedling cultivation of rice technical field.

Background technology

Paddy rice is the high temperature short day crop, heat resources and Relationship with Yield are very close, most northern cold ground rice workspace frost-free season weak point, heat resources is poor, and the improvements in early spring are late, ground temperature is low, and difficulty fetches earth, particularly early spring, chilling injury was frequent, cause seedling raise period to postpone, influence the paddy rice late growing stage and grow, the output that has seriously restricted paddy rice improves.

The utility model content

The purpose of this utility model is for solving northern cold ground rice workspace frost-free season weak point, heat resources is poor, the improvements in early spring are late, ground temperature is low, difficulty fetches earth, particularly early spring, chilling injury was frequent, caused seedling raise period to postpone, and influenced the paddy rice late growing stage and grew, seriously restricted the problem that rice yield improves, and then a kind of northern paddy rice in cold region ferment material bed of growing seedlings is provided.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises: square geosyncline, ferment material and ground surface soil, described ferment material are layered on the bottom in the square geosyncline equably, and described ground surface soil covers the top of ferment material in the square geosyncline.

The utility model is fit to the cultivation of achieving higher output of cold ground rice workspace paddy rice, its advantage is: the ferment material bed of growing seedlings can improve ground temperature: ferment material plays every cool, insulation, effectively improves seedbed ground temperature: ferment material is grown seedlings and is realized warm sowing in bed kind, bed temperature increases more than 3 ℃, and seedling age improved 100～130 ℃ of ground temperature in 35～40 days.Early emerged 3～4 days, early grow seedlings in addition and grabbed 100 ℃ of accumulated temperature in 7 days, nursery period, can increase by 200～230 ℃ of accumulated temperature.

Seedling-growing-up effect is outstanding: the planting percent height, can cultivate the strong seedling of above the average age for marriage band tiller, ferment material is grown seedlings and can be improved rice shoot band tiller rate, along with the seedling growing process science is supporting, effect is also all the more obvious, bed is laid on the ferment material bed down and is used bowl plate seeding, and 35 day length of time rice seedlings grow band tiller rate all reaches 100%, can bring out the strong seedling of 4.5～5.5 leaf seedlings band tillers, two tiller rates 60% of raise seedling in greenhouse wherein, single tiller rate 40%.The rice shoot well developed root system, on the ground, underground growth coordinates.Circularity reaches more than 7.0.Ferment material all seedbeds of growing seedlings never have damping off to take place.

Accelerate growing process: same kind increases by 0.5 leaf under the ferment material condition, and productive tiller stage prolongs 6～8 days, and particularly the late growth stage effective tiller increases and accelerates percentage of earbearing tiller height.

Increasing both production and income, cost-saving synergistic: economize kind, saving of labor, light, the minimizing pesticide dosage of disease, 300 yuan of hectare saving agricultural chemicals and labor management expenses.Can give full play to the yield potential of good quality and high output late variety, more than 10%, hectare increases production 770 kilograms of paddy than the conventional cultivation volume increase.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Embodiment

The utility model preferred implementation is seen Fig. 1 and Fig. 2, comprising: square geosyncline 1, ferment material 2 and ground surface soil 3, described ferment material 2 are layered on the bottom in the square geosyncline 1 equably, and described ground surface soil 3 covers the top of ferment material 2 in the square geosyncline 1.Described ferment material is the dry branches and fallen leaves of stalk, leaf or other plant of livestock packing ring grass, cutted straw, rice Westerner, rice husk, fragmentation.

Make bed: the ferment material place mat should equate or have more 5～10cm with the seedbed size wholely.

Autumn is done bed technique: after integral body is done a seedbed crop harvesting, remove the root stubble, dig 30～40cm with under the seedbed, around the soil branch is put, ferment material is thrown at the peaceful bed end (squarely geosyncline shape) in groove, the laying depth of described ferment material is 10～20cm, paves after the compacting in the ground surface soil backfill bed that digs out, the backfill thickness of described ground surface soil is 10～25cm, and the leveling rake carefully reaches state to be broadcast.

Segmentation is made bed and is dug the one section ferment material in shop, one section seedbed, and back one section earthen backfill of digging out was completed in the bed of ferment material (in the groove) in the last period, carries out successively, flattens the compacting bed surface at last.

Spring is done bed technique: remove ground, seedbed accumulated snow at the beginning of 3 months, preceding 10～15 days button canopies of growing seedlings thaw, and change one deck, dig one deck, and the soil branch is put four limits, dig about dark 20cm, and the peaceful bed end, shop ferment material (if ferment material is few, even shop 10cm is thick also effective) method is made bed with the autumn.

Claims
