Abstract
The invention relates to the technical field of plant cultivation, in particular to a high yield cultivation method for silvergrass in North China. The cultivation method comprises the following steps: selection of land, selecting the wide, fertile and humid land for planting; preparation of land, preparing the land after the soil is thawed out, getting rid of weeds, plowing, ridging, and preserving soil moisture timely; timely planting, selecting good root stocks to cut into small segments of 15 cm, while the planting density is 4 to 6 segments per square meter, and covering soil timely; seedling stage management, loosening the soil and getting rid of weeds timely after the root stocks are survived and germinated; and nurture management, watering timely and fertilizing in proper time. After fruits fall down, the silvergrass can be harvested. The invention relates to a high yield cultivation method for silvergrass, and the cultivation method has the characteristics of high yield and stable yield, so that the silvergrass can be cultivated in large-scale, and the average product is 1 ton in the first, 12 tons in the second year and 20 tons in the third year, therefore, the cultivation method is easy for wide popularization in North China.
Description
Technical field
The present invention relates to field of plant growing technology, relate in particular to a kind of reed at the high-yield cultivating method of north of China.
Background technology
Reed (Triarrhena sacchariflora) original seed originates in East Asia, for grass family reed belongs to herbaceos perennial, and 2 meters of Gao Keda, the shape of growing thickly.Blade is flat, and is wide linear, long 20～50cm, and wide 15～18 millimeters, the two sides is without hair except the close living pubescence of top base portion, and the edge zigzag is coarse, and base portion often is shrunk to handle, the long gradually point in top, middle arteries and veins white, sturdy.Panicle is dredged generate umbrella room shape, long 10～20cm, wide about 10cm.Main shaft is without hair, and 10～20 pieces of thinner and more delicate branches of tool are given birth to pubescence between armpit, uprightly then carry out; Long 4～8 millimeters between the raceme joint, or the tool pubescence; Slightly expand on small ear handle top, and Chang Sheng has pubescence between the base portion armpit, long 1～2 millimeter of short handle, long 3～5 millimeters of long handle; Small ear wire lanceolar, long 5～5.5 millimeters, ripe rear band brown.
Reed is one of comparatively desirable draft energy crop, also can be used as garden landscape, papermaking and other purposes.It can adapt to polytype soil, but on the soil of pH value 6.0～8.0 equal normal growths, especially like sunny and springy land.Reed photosynthetic efficiency is high, is the C4 plant, and dry matter production is up to per hectare more than 20 tons.
Domestic culture technique research for reed is less, and wherein take the research of Beijing Forestry University as representative, they think that reed high yield and quality cultivation control measures are: planting density is with 2-4 strain/m
2Be advisable, irrigation, fertilizer treatment are to irrigate+to make up better without fertilising, nothing irrigation+medium fertilizing amount and irrigation+medium fertilizing amount; The harvesting time is advisable with the harvesting in winter.
Summary of the invention
The object of the present invention is to provide a kind of reed in the high-yield culture technique of north of China, satisfy the requirement of biomass energy.The technical solution used in the present invention comprises the steps:
1. reed is at the high-yield cultivating method of north of China, its feature following steps:
(A), selection of land: ground moistening: moisture 20～60%, fertile: the content of organic matter 80～100g/kg, available nitrogen content 140～200mg/kg, available phosphorus contents 40～70mg/kg, quick-acting potassium content 600～1000mg/kg, and pH value 6.0～8.0;
(B), wholely; Remove weeds until the soil rear whole ground that thaws spring, and 20～25cm turns over; Wait showing rake the soil level after soil is done ridging, in time soil moisture conservation;
(C), in good time plantation: when the plant division bud begins to sprout on the root-like stock, choose plant more than or equal to 150cm, breed without the annual root-like stock of damage by disease and insect plant this moment, root-like stock is cut into the segment of 15～20cm, every section with 2～3 joints, distance by each 50～70cm of spacing in the rows is inserted in the furrow of dark 10～15cm one by one, and density is at 4～6 sections/m
2, the furrow pre-sowing watering makes the soil moisture content of the degree of depth 10～30cm 40～60%, then earthing to improve survival rate after pouring water.
(D), seedling management: after rhizome is emerged, in time weed with a hoe; Keep ground moistening during seedling, along with growing tall of seedling, suitably increase irrigation quantity, keep soil surface to the moisture of 30cm 50～60%, along with growing tall of seedling, after 1 month, suitably reduce irrigation quantity, make soil surface to the moisture of 30cm 20～40%;
(E), tending management: at sealing fertilizer mid-June, consumption 50～75kg/hm
2, N: P: K mass ratio=1: 1: 1; Execute one time fertilizer, consumption 1500kg/hm in mid-September
2, make the sturdy growth of subterranean stem;
(F), harvest in proper late: when moisture low: acrial part water content 10%-15%, gather when infructescence has all been flown away.
The present invention also has following features:
1, during whole ground ridging, row spacing 70cm, the ridge shoulder is neat.
2, tending management at any time weeding during rainy season, after September without weeding.
3, in reed growth and development process, keep in the dark soil layer of 20cm nitrogenous 55～65kg/hm
2, phosphorus is 70～80kg/hm
2, potassium is 50～60kg/hm
2
The present invention is the high-yield culture technique of a kind of relevant reed, has high yield, stable yields characteristics, can realize large-scale planting, and the average yield First Year is 1 ton of per hectare, 12 tons of Second Year per hectares, the 3rd year 20 tons; Be easy at the north of China spread.
Embodiment
The art of this patent is applicable to reed (Triarrhena sacchariflora) in the high-yield culture technique of Northern Part of China.
Embodiment 1:
Be laid in regions in Harbin City, 45 ° 40 ' 52.53 of north latitude " 126 ° 36 ' 57.72 of east longitude ", height above sea level 173m this sample.
