Abstract
The present invention belongs to water saving technology field of agricultural and forestry. The underground mulching water stop is formed by digging 0.5-1 m depth ditch in hill or slope and burying the mulching to ditch wall. The present invention makes it possible to intercept interflow and runoff for crop to absorb and results in obvious water-saving effect, and is suitable for upland field, orchard and waste mountain greening.
Description
The present invention is a kind of underground mulching water-intercepting wall, belongs to farming, forestry water-saving technology field, the particularly farming in arid, hillside fields, mountain area, forestry water-saving technology.
Water-saving agricultural technology is the only way of arid biogeographic zone farming, forest development.At present, water saving such as drip irrigation, mist filling, sprinkling irrigation irrigation technique water-saving result is remarkable, and general equal can the water saving more than 50%, but its cost of investment height, complex process are difficult in China's arid poor mountain area large tracts of land development backward in economy, with a varied topography.
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art and provide a kind of water-saving benefit remarkable, with low cost, technology is simple, is suitable for underground mulching water-intercepting wall farming, forestry water saving new technology that China's Drought Mountain Area, hillside fields are greatly developed.
Purpose of the present invention can reach by following measure: 0.5 meter～1.0 meters of hillside fields ditching (hole) degree of depth, bury mulch film underground along ditch (hole) wall.
Purpose of the present invention can also reach by following measure: along the contour ditching, wall is vertically buried mulch film underground below ditch in the hillside fields; Wall laying plastic below crop-planting hole is filled out field planting crop behind the loam, after the wall in crop-planting hole is laid mulch film bag of the no end, is filled out loam, and the field planting crop.
Description of drawings:
Fig. 1 is the embodiment of the invention one structure chart
Fig. 2 is the embodiment of the invention two structure charts
Fig. 3 is the embodiment of the invention three structure charts
The present invention is described further below in conjunction with accompanying drawing:
As shown in Figure 1: in Cao Po upper edge, deserted mountain contour ditching (1), 0.5～1.0 meter of ditch depth, wall is vertically buried mulch film (2) underground below ditch, form water stop, can tackle runoff and interflow and attract to utilize the afforestation of to economize on water for plant, or make the dry farming farmland, plant crops.
As shown in Figure 2: the below wall in plantation hole (3), vertical laying plastic (4) raises fruit trees or plant after filling out loam.
As shown in Figure 3: the wall in plantation hole (3) is laid no end mulch film bag (5), fills out field planting fruit tree behind the loam.
Above mulch film all can adopt common agripast mulch film, raises fruit trees and also can adopt degradable mulch (degradation time is 1-2).
The present invention compares prior art and has following advantage:
This technology both can be used for the dry farming farmland, can be used for again cultivation of fruit tree and deserted mountain revegetation:
1, dry farming farmland: vertically bury mulch film underground along the contour ditching in the nonirrigated farmland and form water stop, can The interception interflow absorbs for crop, reaches the purpose of water saving and crop yield. Can to the xerocline tableland Reduce the evaporation of field bund and domatic moisture, alleviate the period of short-term drought in the crop growth period, increase crop and steam Rise the ratio of shared soil moisture, improve crop to the effective rate of utilization of soil moisture, increase farming The produce amount. Loess plateau test 2 years, the potato contrast district volume increase 50-80% of plantation.
2, fruit growing: the wall laying plastic forms water stop interception runoff and interflow below the planting fruit trees hole, and tree absorbs in fruit offerings; Or, fill out field planting fruit tree behind the loam in plantation hole wall laying plastic.The underground mulching of filling out loam forms the big nutritious bag at a no end, reduces the seepage of irrigating liquid manure and runs off, and has guaranteed surviving of fruit tree, and water saving is more than 70%.Behind the field planting 1-2, the broken mulch film of shovel is in order to avoid influence the fruit tree root system development.The comparison of the mango survival rate in 2 years of test plantation is according to improving 10-20%, and growth rate improves about 20%.
3, revegetation: the wall laying plastic forms water stop below the fish scale pit of revegetation excavation or contour cultivation ditch, and interception runoff and interflow make full use of natural rainfall and carry out revegetation for the plant absorbing utilization.Woods grass seeds survival rate such as the emblic of test plantation, Ji Maliu, seal chinaberry and growth rate all are higher than contrast significantly.The emblic one annual height of tree that adopts the plantation of underground mulching core wall afforestation technology is than the high 30.6cm of conventional afforestation, and increasing degree is 43.6%; Leading thread increases 0.9cm, and increasing degree is 64.3%.Chicken fiber crops willow exceeds 18.8cm than the average height of tree of conventional afforestation, and increasing degree is 38.1%; Increase the thick 0.9cm of leading thread, increasing degree 100.0%.
4, the underground mulching water-intercepting wall technology is carried out agricultural (forestry) production by making full use of natural rainfall, water-saving benefit is remarkable, the agricultural use effect of increasing production is obvious, forestry utilizes the effect of revegetation obviously to improve, compare with water savings irrigations such as drip irrigation, mist filling, sprinkling irrigations, have characteristics such as with low cost, simple, be suitable for China's Drought Mountain Area and greatly develop.
Claims (4)
