Compared with flood and furrow irrigations, which generate large extremes in wetting and drying soils, low-volume irrigation systems such assurface/subsurface drip and microsprinkler irrigation usually have lower overall N2O fluxes (Nelson and Terry, 1996;Kallenbach et al., 2010;Burger and Horwath,...
The results from the present study have implications for soil management in areas using flood and furrow irrigation with soils susceptible to preferential flow. Tillage depth is a factor that is likely to have a great impact on the amount of water that reaches the soil matrix. Increasing tillage...
3) normal irrigation with water layer 常规淹灌 1. To contrast infiltration irrigation through shallow furrow withnormal irrigation with water layer. 结果表明,在高温多雨的气候条件下,水稻浅沟渗灌栽培技术既可大幅度节水,又能显著提高产量,与常规淹灌栽培相比,浅沟渗灌技术在早稻的整个栽培过程中,可节水3129...
4) cross clope furrow irrigation 横向沟灌5) reverse grouting 逆向灌注 1. By the use of pressure resulted from grouting and the way of ball down,ball down mechanical hydraulic reverse grouter realizes machanical desplacement control,completes cementing operation of reverse grouting in boreholes ...
Normal rainfall provides insufficient water depth in the furrows to hatch many eggs, but crown-flood irrigation hatches large numbers. Therefore, irrigation during periods of drought stimulates mosquito production... CG Alan,JH Frank - 《Environmental Entomology》 被引量: 11发表: 1981年 Establishment...
A flood irrigation system comprising a channel (10) a number of furrows (12) having canals (14) leading therefrom and has the water distribution controlled as follows. Within each furrow are gates (20) that divide each furrow into areas from which the canals lead-off. Each gate (20) ...
(6) for conducting a flow of flood irrigation water between furrows (7) and long enough to cover the length of said furrows; said film (1) has along all the longitudinal section thereof a plurality of equidistant or non-equidistant perforations (2), and frangible sections demarcated by ...
irrigation water between furrows, and long enough to cover the length of the furrows; said film includes along its entire length, distributed equidistantly or not, a large amount of perforations and/or frangible sections defined by tapering lines or by a succession of small perforations or ...
Blocked furrowGuayule (Parthenium argentatum) is a woody, perennial desert shrub, native to the arid American Southwest. It produces natural rubber that can be used to replace Hevea natural rubber for U.S. domestic rubber demands. Irrigation water application and practices form an important ...
Both basin flooding and ridge-and furrow irrigation succeeded in charging the first 6 ft. of soil with between 10 and 12 in. of stored available water. Maize roots failed to penetrate more than 2 ft. into the heavy wet soil, and the crops died without using the water stored between the...
