Remote sensing has shown promise as a tool for site-specific management in agricultural application and production. Earth-observing satellite systems have an advantage for large-scale analysis at regional levels but are limited in spatial resolution. High-resolution satellite systems have been available in recent years, but scheduling these systems for appropriate bands, location of flight, proper altitude, and time of acquisition is difficult. Airborne remote sensing systems offer a flexible, do-it-yourself platform to configure for high quality, high spatial resolution imagery at any desired spectral combination, location, altitude, and time. Use of airborne hyperspectral remote sensing in agriculture has been steadily increasing during the past decade. Compared with hyperspectral systems, multispectral systems are much lower in cost and are less data-intensive. Airborne multispectral techniques are cost-effective and still a good source of crop, soil, or ground cover information for agricultural application and production. This paper investigates three different types of multispectral imaging systems for airborne remote sensing to support site-specific management in agricultural application and production. The three systems have been used in agricultural studies. They range from low-cost to relatively high-cost, manually operated to automated, multispectral composite imaging with a single camera and individual imaging with assembly of separate cameras. Practical issues regarding use of the imaging systems are described and discussed. The advantages and disadvantages of each system are summarized and compared in different configurations. The information is provided for developing practical aerial remote sensing systems. System applications are suitable for fixed-wing aircraft and unmanned autonomous helicopter or fixed-wing platforms.

比较美国血制品饲喂断奶仔猪的氨基酸消化率

血制品常常在断奶仔猪料中使用,但在生产过程中不同的加工工艺可导致不同血制品的氨基酸(AA)消化率也不相同。然而,关于不同血制品饲喂断奶仔猪的氨基酸标准回肠消化率(SID)的差异比较,目前还未有数据。因此,本试验的目的是比较喷雾干燥血粉(SDAB)、喷雾干燥血球粉(SDBC)、喷雾干燥血浆蛋白(SDPP)、禽血粉(ABM)和猪血粉(PBM)分别饲喂断奶仔猪的粗蛋白质(CP)和氨基酸(AA)的标准回肠消化率(SID)。试验选用7头断奶阉公猪[初始体重(11.5±1.1)kg]在回肠末端安装一个T型瘘管,采用7×7拉丁方试验设计,每个拉丁方含有7种日粮和7个阶段(即7 d的试验期)两个因素。其中1种日粮以酪蛋白为基础日粮,5种日粮以酪蛋白和每一种血制品的混合物为基础日粮,使用无氮日粮测量氨基酸和粗蛋白质的基础内源性损失。SDAB、SDBC和SDPP的粗蛋白质标准回肠消化率高于ABM和PBM(分别为1.040、0.945、0.995、0.704和0.689)。SDAB(0.998)、SDBC(0.976)和SDPP(0.981)的赖氨酸的标准回肠消化率比ABM(0.740)和PBM(0.786)的标准回肠消化率高(P0.05)。SDAB、SDBC和SDPP的必需氨基酸平均标准回肠消化率比ABM和PBM的高(P<0.01)。SDAB、SDBC和SDPP的总氨基酸平均标准回肠消化率高于(P<0.01)ABM和PBM的总氨基酸平均标准回肠消化率。总之,SDAB、SDBC和SDPP的氨基酸标准回肠消化率比ABM和PBM的氨基酸标准回肠消化率高,这表明在断奶仔猪日粮中添加喷雾干燥血制品优于添加血粉产品。禽血粉或猪血粉饲喂断奶仔猪的氨基酸标准回肠消化率没有差异。

Remote sensing was used in a series of experiments over a three-year period to obtain spectral reflectance data for studying differences in vegetation indices between grasses, broadleaf plants, and grass/broadleaf plant mixtures. Selected non-crop winter and spring host plants of tarnished plant bug, Lygus lineolaris, were planted in field-plot experiments. Multispectral reflectance data were aerially acquired with both a Real-Time Digital Airborne Camera System (RDACS) sensor and Geospatial Systems (Duncan Tech) MS-2100 multispectral camera. The following six vegetation indices of spectral reflectance were evaluated in this study: normalized difference vegetation index, ratio vegetation index, green normalized difference vegetation index, green vegetation index, green ratio vegetation index, and Ashburn vegetation index. Vegetation indices calculated with imagery data for the grasses and broadleaves differed significantly;there appeared to be more discriminating differences between vegetation indices for grasses and broadleaf plants when the indices were based on a combination of green and near infrared or green and red spectral bands than when the indices were based on red and near infrared spectral bands. Insect data from these studies confirm that tarnished plant bug prefers broadleaf host plants, but can use Italian ryegrass for food and reproduction. The narrow temporal window of host suitability for Italian ryegrass may limit its significance. Herbicide destruction of broadleaf host plants in early spring prevented the tarnished plant bug population increases that occurred in untreated plots. Findings of this study would be useful in site-specific vegetation management decisions in programs such as the prototypical area-wide tarnished plant bug management experiment conducted in the Delta region of Mississippi.
