农机安全生产事关广大人民群众生命和财产安全,做好这项工作,是统筹城乡经济发展、全面建设小康社会的重要内容,也是实践"三个代表"重要思想的具体表现.目前农村经济正处于转型期,由于受生产力发展水平和广大农民素质等因素的制约和影响,农村安全生产基础薄弱,农机安全生产形势相当严峻.农机重大事故的频繁发生,将直接影响到农村经济可持续健康发展和全面建设小康社会目标的实现.为保障广大农民群众生命财产,促进农村社会稳定,各级政府和部门必须充分认识到抓好农机安全生产的必要性、艰巨性和紧迫性,从农村经济和社会发展全局出发,对农机安全生产工作引起足够重视,制定和实施好"十一五"期间农机安全生产发展规划. 相似文献

Plants with different abilities for osmotic adjustment (cowpea, bean, and sugarbeet) were subjected to gradually decreasing
soil water content. During the development of water deficit stress, various plant water parameters were measured to characterize
their relationship to the near infrared R
1300/R
1450 leaf water index, which is based on the measurement of light reflected from leaves. In all three species, leaf water thickness
(LWT), leaf cell relative water content (RWC), and overall leaf thickness remained relatively constant under moderate water
deficit stress. However, at the point when plants could no longer cope with the increasing level of water deficit stress,
LWT, RWC, and leaf thickness were found to decrease substantially, signaling the onset of leaf dehydration. The R
1300/R
1450 leaf water index followed the RWC very closely in cowpea and bean leaves, and with some time lag in sugarbeet leaves. The
R
1300/R
1450 index may therefore be used as a feedback-signal in precision irrigation control, signaling effectively the physiological
response of plants when water deficit stress becomes detrimental. RWC and the R
1300/R
1450 index were linearly correlated in cowpea and bean leaves, but not in sugarbeet leaves. 相似文献

The implementation of nutrient management plans for confined animal feeding operations requires recording N and P loads from land-applied manure, including nutrients applied in irrigation water from manure treatment lagoons. By regulation, lagoon irrigation water nutrient records in Mississippi must be based on at least one lagoon water nutrient analysis annually. Research in Mississippi has shown that N and P levels in lagoon water, and the N:P ratio, vary significantly through the year. Nutrient estimates based on one annual analysis do not account for this variability and may overestimate or underestimate N and P loads. The present study reports an improved method to more precisely estimate N and P loads in irrigation water from swine manure lagoons. The method is based on predictable annual cycles of N and P levels in lagoon water and employs simple curve-fitting of lagoon-specific formulas derived by analyses of historical data. Similarity of curves from analyses of Mississippi lagoons and other lagoon studies suggests that the method can be applied using the often limited nutrient data for a lagoon to more precisely estimate seasonal shifts of N and P and to improve the precision of estimates for N and P in irrigation water. Although the present study focused on swine manure lagoons in the southern US, recognition that the annual N cycle in lagoon water is temperature driven, suggests that additional research incorporating temperature into future models could extend these models to other types of waste treatment lagoons and climates. 相似文献

This study deals with the effects of intermittent irrigation on actual evapotranspiration (ET) and leaf area index (LAI) of “Superior” grapevines grown in a semiarid environment in northeastern Brazil. The field experiments were carried out during two consecutive fruiting cycles (dry season and rainy season) of grapevines (Vitis vinifera, L) irrigated by drip at a rate of 2.3 L h−1. Four irrigation time intervals were used as follow: one turn irrigation-time (I-1), two turn irrigation-time (I-2), three turn irrigation-time (I-3), and four turn irrigation-time (I-4). The growing cycles received different amounts of water by irrigation, which for dry and rainy seasons were 470.5 and 243.5 mm, respectively. The ET increased from 5.7 to 7.5 mm day−1 when the irrigation time interval changed from I-1 to I-4 and resulted in a higher value of LAI. The values of ET during the rainy-season growing cycle were much lower throughout the phenological stages, reaching a maximum of 6.4 mm day−1 for I-4 in the maturation stage. For both growing cycles, an increase in the cumulated vineyard evapotranspiration was observed when changing the irrigation time interval from I-1 to I-4, except I-2, which was slightly greater than I-3. Soil water drainage had a very gradual exponential decrease from I-1 to I-4 in both fruiting cycles. The grapevine coefficient under intermittent irrigation can be described as function of days after pruning by polynomial models. 相似文献

Water and land salinization, caused by ill-practiced irrigation and drainage is acute and widespread in Karakalpakstan, Uzbekistan.
A crop frequently grown in these marginal areas is sorghum because of its capability to adapt to saline conditions. However,
the salt uptake potential of local varieties for salt-ameliorative purposes, as well as possible income-generation benefits,
have not yet been studied. Therefore, field experiments on low, medium and highly saline soils were conducted using four sorghum
cultivars (S. vulgare, S. cernuum, S. durra, and S. technicum). The effect of soil salinity on biomass, stover and grain yield, the baking and feed quality, and total water soluble salt
(TDS) accumulation, was assessed according to varieties, plant fractions and growth phases. Results showed that S. cernuum had the highest grain yield on the low (5.13 t ha−1), medium (6.05 t ha−1) and highly (3.3 t ha−1) saline soil. S. technicum showed the lowest growth potential under all salinity levels. TDS accumulation varied between 406 and 185 kg ha−1 depending on variety, site, plant fractions and growth stage. Irrespective of the soil salinity levels and varieties, TDS
was highest in stover and leaves, while highest TDS uptake, mainly chlorides and bicarbonates, occurred between booting and
flowering. Baking quality of all varieties was extremely low, whereas the in-vitro feed was assessed as of medium quality.
The findings indicate the scope of local sorghum varieties for phytomelioration of marginal lands in Karakalpakstan, while
concurrently satisfying a wider range of rural livelihood needs. 相似文献
