Abstract

The upland interplanting rice-growing method is characterized by ridge forming on upland, adopting water-collecting measure, covering with plastic film, planting rice and interplanting corn or cotton and vegetable. It is a scientific, water-saving and space cultivation method, and can fully utilize land resources and is simple in operation, etc..

Description

Intercropping cultivation of rice in dry land

The invention belongs to a kind of cultivation method that covers nonirrigated farmland rice cultivation crop with plastic film.

In existing rice crop cultivation, have paddy field carry out conventional along the field plant, field planting is equidistantly gone in the field planting of branch railway carriage or compartment, stay cord, the capable field planting of width and the planting types such as rice transplanting of invention in recent years, though be not quite similar, but all be the paddy planting that needs fresh water and fertilizer all many, have shortcomings such as farming paddy field difficulty, liquid manure amount are big, time-consuming.

The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of on the nonirrigated farmland new method of rice cultivation crop.

Characteristics of the present invention are to cover nonirrigated farmland rice cultivation, interplant corn or crops such as cotton, vegetables with plastic film, make full use of the purpose that dry farming space and sunlight, expansion rice make area, increase grain aggregate, reduce water and soil loss, save liquid manure thereby reach.It is characterized in that the measure of nonirrigated farmland plastic film mulching plant paddy rice utilization technology of water catchment remains ground moistening, satisfies the water that paddy rice respectively grows; Be that also an interplant corn or other Dry crops such as cotton, vegetables are colonizated on the ridge, ridge (railway carriage or compartment, peak), needing to help the few Dry crop of water to grow, overcome many and the contradictions with piece ground plant between few of paddy rice water consumption, also solved some problems of rice dry-farming with the Dry crop water consumption.

The concrete pattern of the present invention can be represented with accompanying drawing.

Fig. 1 is the local interplant crop of the present invention pattern diagram.

Fig. 2 is the local field planting paddy rice of the present invention pattern diagram.

Below with reference to accompanying drawing the concrete pattern of the present invention and the methods of cultivation are further described.

In the accompanying drawing 1-2, need water that the few Dry crop corn or the summit both sides in railway carriage or compartments, peak, ridge, field planting position 1 such as cotton, vegetables are respectively done a vertical shallow and little field planting ditch 5.Need to do earlier on the plane of water to many paddy railway carriage or compartments, ridge, rice crop field planting position 2 some laterally equidistant shallow and little paddy rice field planting collecting ditchs 4, laterally do some little and short water ridge, hurdle 3 behind the covered with plastic film again.

The present invention is achieved in that promptly to be turned over earlier in the nonirrigated farmland and decides railway carriage or compartment ridging (ridge is laterally done in the hillside fields) formation railway carriage or compartment, peak, ridge and paddy railway carriage or compartment, ridge and use sufficient base fertilizer separately, makes preparations for sowing for the soil disinfection desinsection behind the water of secondly whole thin filling vola.On paddy railway carriage or compartment, the ridge face that makes preparations for sowing, laterally make equidistantly shallow and little paddy rice field planting collecting ditch then by rational close planting, the paddy rice program request also can shoot transplanting equipment on the field planting collecting ditch; On the railway carriage or compartment, peak, ridge that makes preparations for sowing, vertically make two parallel Dry crop field planting ditches again,

With Dry crops such as corn or cotton, vegetables on the live or transplanting dry farming thing field planting ditch.At last planting on paddy railway carriage or compartment, the ridge face of rice crop covered with plastic film and pressing with soil compaction, keep at a certain distance away on plastic film and do some little and short hurdle hydraulics in case rainwater runs off, rupture of membranes is emerged and is strengthened farming season and manage when treating that rice seedling grows to two leaves.

Realization of the present invention can be used the work flowcharting, and promptly ridge (hillside fields is laterally done) → use sufficient base fertilizer → the whole shallow and little field planting collecting ditch → sowing → epiphragma of soil insect → do → make hurdle hydraulic → rupture of membranes to emerge → manage farming season of going out of carefully pouring water → sterilize is made in real tillage → decide railway carriage or compartment.Sow after also can covering plastic film earlier in the flow process, also can first epiphragma after the transplanting rice rice shoot.

Intercropping cultivation of rice in dry land of the present invention compared with prior art, have enlarge that rice makes area, increases grain aggregate, rationally utilizes photo-thermal, realizes multi-storied agriculture, saves fresh water and fertilizer, suitable water conservation soil, easy and simple to handle, the characteristics that are easy to promote, real is the desirable cultivation method of scientific farming, water-saving agriculture.

Claims

1, a kind of water-saving stereo agricultural cultivation method that makes full use of nonirrigated farmland intercropping rice crop is characterized in that deciding the railway carriage or compartment and makes the ridge covered with plastic film: railway carriage or compartment, peak, ridge [1] plantation needs the few Dry crop of water, and paddy railway carriage or compartment, ridge [2] plantation needs the many rice crops of water.

2, according to claim 1ly decide the railway carriage or compartment and do the ridge, it is characterized in that referring to that the hillside fields laterally does the ridge and should collect rainwater and reduce water and soil loss, the ridge is arbitrarily done on the level land.

3, railway carriage or compartment, peak, ridge according to claim 1 [1] and paddy railway carriage or compartment, ridge [2] is characterized in that doing on the face of railway carriage or compartment that hurdle Shui Geng [3] and collecting ditch [4] and dry farming ditch [5] are arranged.

4, hurdle Shui Geng according to claim 3 [3] is characterized in that behind the covered with plastic film of nonirrigated farmland doing in the lateral separation the little and short cement ridge, hurdle.

5, collecting ditch according to claim 3 [4] is characterized in that laterally equidistantly and abreast doing on the plane, paddy railway carriage or compartment, ridge little and shallow paddy rice field planting ditch.

6, Dry crop according to claim 1 is characterized in that referring to crops such as the few corn of water requirement, cotton, peanut, wheat, vegetables.

7,, it is characterized in that finger becomes coloured films such as plastic sheeting for farm use, mulch film, mocromembrane with plastic processing according to claim 1 and the described plastic film of claim 4.
