农业机械化是促进农业农村现代化发展的有力保障,是实现现代农业经济快速健康发展的重要保障。贵州主要以丘陵山地为主,农业机械化发展缓慢,农机化水平较低。基于此,课题组主要阐述了贵州2022年发展农业机械化取得的成效,分析了贵州在发展农业机械化过程中存在机具作业地形条件差、现有农机具适应性弱、农机与农艺匹配性差、农机服务能力差距大、农机管理机制不畅、安全监管能力不足等问题,并从发挥农机化的重要作用、抓好农机化的关键环节、抓好农机化整体水平提升三方面提出了贵州农业机械化的发展思路,以期为贵州农业机械化发展建言献策,不断提升农作物生产机械化的整体水平,加快农业机械化向全程全面和高质量发展,走出一条丘陵山区农业机械化发展的新路子。 相似文献

正农业机械化培训工作是农机化工作的重要组成部分,农业机械化培训工作的好坏,直接影响着农机新技术、新机具的推广应用、农机作业效率、农机手的收入和农民的人身财产安全。因此不断创新农业机械化培训方式和内容,使农业机械化培训工作紧跟农机化的发展步伐,是每个农机工作者必须研究的课题。1农业机械化技术培训基本情况近年来随着农机购置补贴、农机作业补贴等一系列惠农政策的出台,我市各类农机具保有量增长迅速,特别是大中型农机 相似文献

A model to represent the discolouration of dried powder of carrots as a function of temperature was developed. Two types of carrots, Asian and European, containing large amount of lycopene and β-carotene, respectively, were tested. The dried powder was stored under an atmosphere with O2and at three different temperatures, 5,20 and 35°C. The surface colour of the powder was monitored during storage by a Hunter colour ratioa/b. In the proposed model, the rate of oxidation was assumed to be represented by the product of the fraction of concentration of oxidized pigment at arbitrary time and a specific rate of oxidation of pigment. The rate parameters in the proposed model were calculated by fitting the experimental data with smooth curves by trial and error at the end of the induction period but before discolouration took place. The frequency constant and activation energy, expressing the temperature dependence of the rate parameters, were expressed by the Arrhenius relation. The simulation results of a Hunter colour ratioa/bof dried powder at 25°C showed good agreement with the experimental data, suggesting that the proposed model was effective for the prediction of discolouration of dried powder of both types of carrot. The use of the induction period in the manner described may enable the shelf life of dried powder to be predicted. 相似文献

The fractional outflow rate of water from the rumen, measured as the rate of disappearance of the chromium complex of ethylenediamine tetra-acetic acid, was related to a number of dietary factors. A multiple regression equation was derived which expressed fractional outflow rate as a function of the intakes of dry matter, ash, acid-detergent fibre and crude protein.The data analysed consisted of 243 observations for sheep on 59 diets, including forage, concentrate and mixed diets. The ranges covered by the data were: fractional outflow rate 0.7–3.6 day?1; dry matter intake 560–1400g/day; ash 4–30%, acid-detergent fibre 7–41%, crude protein 5–26 % of dry matter; there were no observations for sheep of less than 34 kg liveweight.The equation accounted for 56·3 % of the total variance. Between-sheep variance could not be calculated for the whole of the data but was undoubtedly substantial since, for a sixth of the data, it was known to account for 38 % of the total variance. 相似文献
