籽瓜收获机械研究现状与发展展望

籽瓜是我国北部地区重要的经济作物之一,研发适合我国农业现状的籽瓜收获机械,对降低劳动强度、提高籽瓜收获效率及我国农民的经济实力具有重要的意义。为此,分析了国内外籽瓜收获机械的研究现状,结合我国籽瓜种植模式,探讨现有籽瓜收获机械存在的问题,同时指出了籽瓜收获机向大型化、专业化和智能化收获发展的趋势,为提高籽瓜收获机械化水平提供了一定的参考依据。     

"桂橙一号"果实在鹿寨生长发育规律初探

2009年农村推广站对"桂橙一号"的果实生长发育规律进行了观察研究.结果表明,"桂橙一号"果实纵横径总体呈抛物线生长,果实纵、横径净生长量在整个生长过程中均出现三次生长高峰:第一次生长高峰期,纵横径:5月10～30日;第二次生长高峰期,纵径:7月10～30日,横径:7月10日～8月10日;第三次生长高峰期,纵径:9月10～30日,横径:8月30～9月30日;进入8月由于高温干旱果实生长缓慢,9月10日后气温开始下降,横径比纵径提前10 d进入生长高峰期.至10月30日以后纵横径生长趋于缓慢,完全着色前仍未停止生长.

绿色、环保、生态养殖是发展现代化畜牧业的必由之路

当前，畜牧业虽然已逐步向规模化、标准化、产业化的方向发展，然而这种只是片面追求数量和经济利益的最大化，而忽视了产品的绿色、环保和生态指标的模式，正日益受到由此带来的环境污染的冲击，凸显出畜禽及其产品绿色不足、环保不够、生态程度不高，市场竞争力弱的特点。     

WebPIPA （Web Based Paddy Irrigation Productivity Assessment）： An Online Irrigation Water Supply Management for Tanjung Karang Rice Irrigation Scheme （TAKRIS）

Irrigation water management has significant economic implications in developing countries like Malaysia. As in many countries, Malaysia is also espousing internet as a platform of new possibilities for information access and sharing. Thus web based decision tools are pertinent in managing water, which is becoming a source of conflict between domestic, industry and agricultural use in this emerging technological and information age. Decision Support System （DSS） created in the past was theoretically acceptable but practically not effective in the transfer of scientific knowledge from research labs to the end-users to support them in decision making. The Web Based Paddy Irrigation Productivity Assessment （WebPIPA） is an example of DSS created to provide an effective conduit for the transfer of scientific knowledge from research labs to the end-users to support them in decision making. WebPIPA serves as an innovative, user friendly and efficient management tool for run-of-river rice irrigation system. It is a web based program that requires users to login through user name and password WebPIPA is developed using Net framework and ASP. Net Programming Languages of Microsoft. Net 2003 environment. A 3-tier architecture framework was carefully studied and was implemented to create the WebP1PA model. Mathematical model developed for aiding irrigation decisions must be oriented towards addressing various issues in addition to the scientific ones for better acceptability. All government and private agencies, researchers, station users, farmers, investors and buyers related to this study area will be able to access and share the database through the internet. By strengthening the involvement of government departments, the database can be very effectively used by all stakeholders at the same time narrowing the gap between the urban and rural communities in the development of country.     

杂交野猪种公猪的科学饲养管理

杂交野猪是纯正野猪公猪与优良瘦肉型家母猪经多元杂交所产的优质后代,其外貌象野猪.育成后的杂交野猪,既保留了野猪肉营养价值高、瘦肉率高、野味浓郁和富含亚油酸的功效,又具有家猪性情温顺、生长快、个体大、繁殖率高、肉质细嫩等野猪不具备的优点.杂交野猪种公猪应是具有含70%以上野猪血缘的三元杂交野猪公猪.     

不同时期干旱胁迫对谷子农艺性状的影响

采用盆栽控水方法,研究不同生育时期干旱胁迫对谷子物候期、株高、叶片数、顶叶叶面积、穗长、根轮数等农艺性状及产量的影响。结果表明,干旱延迟谷子物候期的出现;拔节期干旱对谷子株高的影响最大;干旱不会引起谷子总叶片数的改变,但对叶片发生时间有一定影响;拔节期干旱和孕穗期干旱使谷子顶叶叶面积减小;干旱抑制谷子根系的生长,但复水后生长迅速恢复。拔节期干旱对谷子农艺性状造成的影响最严重、最持久,干旱胁迫使谷子的产量降低,尤以灌浆期干旱对产量影响最显著。
