澳大利亚畜牧业概况及其研发机制

畜牧业生产概况 欧洲人在澳大利亚定居的最初阶段,澳大利亚的农业主要是种植小麦和饲养绵羊。1900年,羊毛和小麦生产依然是澳大利亚农业的主导,此时澳大利亚开始生产肉牛、奶牛、其他的谷物、水果和蔬菜作物。20世纪初期,澳大利亚政府为农民和主要的生产者提供帮助,鼓励生产、就业和出口,同时设置关税限制某些商品的进口。澳大利亚的畜牧业逐渐发展成以养羊业和养牛业为主,同时还有养禽业和养猪业等多种格局。     

小麦种植新技术与施肥技术要点分析

随着全球人口不断增加,提高小麦产量和质量的需求愈发迫切。然而,传统的种植和施肥技术面临一系列问题,包括品种选择不当、施肥不科学、土壤质量下降以及环境污染等。这些问题威胁着小麦种植的可持续性和农业生产的现代化。为了应对这些挑战,本文提出一系列策略。本文强调了品种选择的重要性,应根据地区的气候和土壤条件选择适宜的小麦品种。科学施肥被强调为提高产量和质量的关键,需要根据土壤检测结果和生长需求,合理施用有机肥、化肥和微量元素。本文还提出了优化措施,如测土配方施肥、水肥一体化、有机农业和科技创新,以进一步提高农业生产效率和保护环境。通过采用这些策略,旨在实现小麦种植的可持续发展,提高产量和质量,促进农业现代化进程。     

农作物病虫害防治中植保无人机的运用

现代农业面临着农作物病虫害防治的挑战,传统方法效率低下且存在安全和环境问题。植保无人机作为一种创新工具,具有高效、安全和精准的特点,在农作物病虫害防治中具有广阔的应用前景。然而,植保无人机的推广仍面临政策、技术和培训等问题。本文提出了三项策略来推动植保无人机的应用和发展。首先,政府需要提供政策支持,制定相关政策和措施,鼓励农民和农业企业积极采用植保无人机。其次,技术研发是关键,需要不断提高植保无人机的性能、稳定性和智能化水平,同时研发适用于不同作物和病虫害的专用农药和喷洒技术。最后,培训与推广也至关重要,通过举办培训班、现场演示和技术交流等方式,提高农民和农业企业的植保无人机操作技能和应用意识。通过以上策略的实施,可以推动植保无人机在农作物病虫害防治中的广泛应用,提高农业生产的效益和可持续性,为粮食安全和农业可持续发展做出贡献。

Overland water and salt flows in a set of rice paddies

Cultivation of paddy rice in semiarid areas of the world faces problems related to water scarcity. This paper aims at characterizing water use in a set of paddies located in the central Ebro basin of Spain using experimentation and computer simulation. A commercial field with six interconnected paddies, with a total area of 5.31 ha, was instrumented to measure discharge and water quality at the inflow and at the runoff outlet. The soil was classified as a Typic Calcixerept, and was characterized by a mild salinity (2.5 dS m⁻¹) and an infiltration rate of 5.8 mm day⁻¹. The evolution of flow depth at all paddies was recorded. Data from the 2002 rice-growing season was elaborated using a mass balance approach to estimate the infiltration rate and the evolution of discharge between paddies. Seasonal crop evapotranspiration, estimated with the surface renewal method, was 731 mm (5.1 mm day⁻¹), very similar to that of other summer cereals grown in the area, like corn. The irrigation input was 1874 mm, deep percolation was 830 mm and surface runoff was 372 mm. Irrigation efficiency was estimated as 41%. The quality of surface runoff water was slightly degraded due to evapoconcentration and to the contact with the soil. During the period 2001–2003, the electrical conductivity of surface runoff water was 54% higher than that of irrigation water. However, the runoff water was suitable for irrigation. A mechanistic mass balance model of inter-paddy water flow permitted to conclude that improvements in irrigation efficiency cannot be easily obtained in the experimental conditions. Since deep percolation losses more than double surface runoff losses, a reduction in irrigation discharge would not have much room for efficiency improvement. Simulations also showed that rice irrigation performance was not negatively affected by the fluctuating inflow hydrograph. These hydrographs are typical of turnouts located at the tail end of tertiary irrigation ditches. In fact, these are the sites where rice has been historically cultivated in the study area, since local soils are often saline-sodic and can only grow paddy rice taking advantage of the low salinity of the irrigation water. The low infiltration rate characteristic of these saline-sodic soils (an experimental value of 3.2 mm day⁻¹ was obtained) combined with a reduced irrigation discharge resulted in a simulated irrigation efficiency of 60%. Paddy rice irrigation efficiency can attain reasonable values in the local saline-sodic soils, where the infiltration rate is clearly smaller than the average daily rice evapotranspiration.

Review of the Egyptian experience in implementing land drainage projects

About 30 years have passed since the Government of Egypt embarked on implementing a series of large scale drainage projects. At present, about 3.8 million acres have been provided with drainage systems on the basis of systematic pre-drainage investigations and designs. The target is to provide drains in approximately 6.4 million acres in the Nile Valley and Delta.The implementation of the subsurface drainage system is carried out by the public sector and private contractors under direct supervision of governmental regional departments. The implementation process depends on many factors related to the drainage material, machinery, manpower, site requirements, farmers and organizations involved. Problems and constraints are sometimes challenging, however, the annual rate of implementation has gradually increased to 170,000 acre/year.This paper discusses the different aspects involved in the implementation process of drainage systems. The development in materials, machinery and construction technologies will be reviewed. Institutional and management factors are going to be also considered.

A European irrigation map for spatially distributed agricultural modelling

We present a pan-European irrigation map based on regional European statistics, a European land use map and a global irrigation map. The map provides spatial information on the distribution of irrigated areas per crop type which allows determining irrigated areas at the level of spatial modelling units. The map is a requirement for a European scale assessment of the impacts of irrigated agriculture on water resources based on spatially distributed modelling of crop growth and water balance. The irrigation map was compiled in a two step procedure. First, irrigated areas were distributed to potentially irrigated crops at a regional level (European statistical regions NUTS3), combining Farm Structure Survey (FSS) data on irrigated area, crop-specific irrigated area for crops whenever available, and total crop area. Second, crop-specific irrigated area was distributed within each statistical region based on the crop distribution given in our land use map. A global map of irrigated areas with a 5′ resolution was used to further constrain the distribution within each NUTS3 based on the density of irrigated areas. The constrained distribution of irrigated areas as taken from statistics to a high resolution dataset enables us to estimate irrigated areas for various spatial entities, including administrative, natural and artificial units, providing a reasonable input scenario for large-scale distributed modelling applications. The dataset bridges a gap between global datasets and detailed regional data on the distribution of irrigated areas and provides information for various assessments and modelling applications.
