Description
Technical field
The present invention relates to a kind of methods for improving ancient riverbed of the Yellow River soil depletion Soils In The Region organic matter, belong to soil ecology neck
Domain.
Background technique
The ancient riverbed of the Yellow River means that the Yellow River invades Huaihe River southwards and is formed by the region that one section of main stem is flowed through, be located at the Yellow River,
Between Huaihe River, North Jiangsu Main Irrigation Canal, 22 Henan, Shandong, Anhui, Su Si province counties (city), overall length 730km, the average width in north and south are flowed through
32.5km, about 2.4 ten thousand km of the soil gross area2, it is unique geographical single to form a natural landscape between Huaihe River and Yellow River basin
Member.The regional soil soil parent material is yellow general alluvial deposits, and for soil types based on moisture soil, soil species is mainly blown sand soil.The soil species
Grittiness weight, it is loosely organized, lack capillary structure, grains of sand cation exchange capacity (CEC) is lower, and preservation capacity of water and fertility is poor, fertility compared with
It is low.
Green manure is to utilize all or part green body caused by growing process, and directly or strange land turns over or passes through
The green plants body for making fertilizer in soil is administered to after stack retting.Green manuring crop can play good retain water and nutrients and improvement
The effect of farmland ecological environment, moreover it is possible to significantly improve soil organic matter content, improvement soil physical and chemical property, reduce the soil weight,
Soil quality is improved, fertilizer amount is reduced, land used is promoted to combine with increasing soil fertility.Meanwhile it being further added by the basis of green manure turns over
Organic fertilizer, increasing for inorganic fertilizer can be further improved soil nutrient content.
Rye grass is mainly planted in orchard or Winter paddy field as excellent green manure kind, does not strive ground with cereal crops, has
Good application prospect.The decay process of rye grass returning to the field has a significant effect to soil fertility and succession crop.Sesbania is
The plant of the rare tool root nodule and the dual nitrogen fixing capacity of stem tumor of plant kingdom, nodule number is more, and nitrogen fixing capacity is strong.Because its have compared with
Big biomass and stronger nitrogen fixing capacity, sesbania is frequently as Fine green manure.Sesbania green manure organic matter rich in, through over-voltage
Blueness is decomposed, and soil property can be cured, and improves soil nature, enhances soil fertility.Forefathers, which study, finds that often turning over 1000kg sesbania makees green manure, quite
Apply the nitrogenous fertilizer of 5kg or more.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for improving ancient riverbed of the Yellow River soil depletion Soils In The Region organic matter, to change
Kind soil environment.
The technical solution of use are as follows:
Pass through green manuring (rye grass-sesbania crop rotation) in ancient riverbed of the Yellow River soil depletion area and turn over, and combines organic
Fertilizer, nitrogenous fertilizer match the method applied, and are remarkably improved the soil organism.Late October, the husky earth in soil depletion area in the ancient riverbed of the Yellow River
Soil block plants rye grass.Before plantation, applying organic manure 500kg/667m2As base fertilizer.Rye grass application rate is 1.5kg/
667m2, Planting Row Distance 60cm.10kg/667m is imposed during Ryegrass Growth2Nitrogenous fertilizer.It is early April next year, upper season is black
Wheat straw turns over, and plants sesbania, application rate 4.0kg/667m2, Planting Row Distance 80cm.8kg/ is imposed in sesbania growth period
667m2Nitrogenous fertilizer.
The utility model has the advantages that
Under this cultivation step, the soil organism reaches 5.7g/kg, than increasing 1.2g/kg before planting, than conventional rice and kernel wheel
Make cultural method and improves 0.5g/kg.The present invention passes through green manuring and turns over, and in conjunction with organic fertilizer-nitrogenous fertilizer with applying, is remarkably improved
Soil organic matter content improves soil quality.
Detailed description of the invention:
Fig. 1 shows increase different amounts of organic fertilizer before plantation rye grass and impose different amounts of nitrogenous fertilizer to the soil organism
It influences.
After Fig. 2 indicates that rye grass turns over, sesbania growth period imposes influence of the different amounts of nitrogenous fertilizer to the soil organism.
Each parameter is as follows in Fig. 1, Fig. 2 regulation method:
Measure 0: soil before plot is planted.Measure 1: local conventional fertilizer application plants wheat.
Measure 2: 300kg/667m is increased before plantation rye grass2Organic fertilizer imposes 8kg/667m2Nitrogenous fertilizer；
Measure 3: 300kg/667m is increased before plantation rye grass2Organic fertilizer imposes 10kg/667m2Nitrogenous fertilizer；
Measure 4: 300kg/667m is increased before plantation rye grass2Organic fertilizer imposes 12kg/667m2Nitrogenous fertilizer；
Measure 5: 500kg/667m is increased before plantation rye grass2Organic fertilizer imposes 8kg/667m2Nitrogenous fertilizer；
Measure 6: 500kg/667m is increased before plantation rye grass2Organic fertilizer imposes 10kg/667m2Nitrogenous fertilizer；
Measure 7: 500kg/667m is increased before plantation rye grass2Organic fertilizer imposes 12kg/667m2Nitrogenous fertilizer；
Measure 8: 700kg/667m is increased before plantation rye grass2Organic fertilizer imposes 8kg/667m2Nitrogenous fertilizer；
