当前城市建设中的关键问题——土地财政

中央接二连三发文调控房地产市场,但均无果而终.最后不得动用行政手段:限购令.但这种用行政手段干预市场的办法只能是应急的措施.房地产市场失控,根本在于地方政府对土地财政的依赖,这个关键问题没有解决,不仅房地产市场难步入正轨,中国的绿色发展也难行.房地产业耗用大量土地,消耗钢材、铝材、水泥、陶瓷…….一旦房地产业背离了民生的本质,成为投资标的物与奢侈品,住房标准严重脱离国情,非理性的住房消费,房地产业则蜕变为高耗能、高排放、高污染的“三高”产业.唯使地方政府摆脱土地财政的依赖,才抓住绿色发展的关键.开征房产税是重要手段,然试行的房产税存在严重误区,有使利器失效之危险.

纺织工业经济指标的灰色预测模型分析

利用灰色系统理论，对我国纺织工业主要经济指标做了建模分析。结果表明，对于生产总值和销售收入，用残差周期修正模型精度较高。对利税额精度极低，说明产值与利税不同步增长。     

稻壳生物炭对整治烟田土壤养分及烟叶产质量的影响

为探究生物炭施用对整治烟田土壤改良及烟叶产质量的影响,在皖南的烟田整治区,研究了稻壳生物炭不同施用量对土壤养分及烟叶产质量的作用效果。结果表明,稻壳生物炭施用可以降低土壤容重,提高土壤pH及有机质、碱解氮、有效磷和速效钾等养分含量。生物炭可以促进烟株生长发育,对烟叶外观产生一定影响,特别是油分指标随生物炭用量增加呈下降趋势。生物炭施用一定程度上降低烟叶总糖及还原糖含量,提高总氮、烟碱及钾含量,其中T2（生物炭7.5 t/hm²）处理烟叶化学成分协调性较好。同时烟叶感官质量随生物炭施用量增加呈现先增加（不变）后降低趋势,感官评吸得分表现为T1=CK> T2> T3。烤烟的产量产值均随着生物炭施用量增加而增加,其中T3（生物炭15 t/hm²）处理最高,产量达1729.2 kg/hm²,产值达到37516.8 元/hm²,较CK分别提高43.51%和43.48%。但上等烟比例随生物炭用量增加呈先增加后降低趋势。综合土壤养分及烟叶的产质量结果,在皖南烟田整治区,稻壳生物炭的施用量不宜超过7.5t/hm²。

Invited review: production and digestion of supplemented dairy cows on pasture

Literature with data from dairy cows on pasture was reviewed to evaluate the effects of supplementation on intake, milk production and composition, and ruminal and postruminal digestion. Low dry matter intake (DMI) of pasture has been identified as a major factor limiting milk production by high producing dairy cows. Pasture DMI in grazing cows is a function of grazing time, biting rate, and bite mass. Concentrate supplementation did not affect biting rate (58 bites/min) or bite mass (0.47 g of DM/bite) but reduced grazing time 12 min/d per kilogram of concentrate compared with unsupplemented cows (574 min/d). Substitution rate, or the reduction in pasture DMI per kilogram of concentrate, is a factor which may explain the variation in milk response to supplementation. A negative relationship exists between substitution rate and milk response; the lower the substitution rate the higher the milk response to supplements. Milk production increases linearly as the amount of concentrate increases from 1.2 to 10 kg DM/d, with an overall milk response of 1 kg milk/kg concentrate. Compared with pasture-only diets, increasing the amount of concentrate supplementation up to 10 kg DM/d increased total DMI 24%, milk production 22%, and milk protein percentage 4%, but reduced milk fat percentage 6%. Compared with dry ground corn, supplementation with nonforage fiber sources or processed corn did not affect total DMI, milk production, or milk composition. Replacing ruminal degradable protein sources with ruminal undegradable protein sources in concentrates did not consistently affect milk production or composition. Forage supplementation did not affect production when substitution rate was high. Fat supplementation increased milk production by 6%, without affecting milk fat and protein content. Increasing concentrate from 1.1 to 10 kg DM/d reduced ruminal pH 0.08 and NH3-N concentration 6.59 mg/dl, compared with pasture-only diets. Replacing dry corn by high moisture corn, steam-flaked or steam-rolled corn, barley, or fiber-based concentrates reduced ruminal NH3-N concentration 4.36 mg/dl. Supplementation did not affect in situ pasture digestion, except for a reduction in rate of degradation when high amounts of concentrate were supplemented. Supplementation with energy concentrates reduced digestibility of neutral detergent fiber and intake of N but did not affect digestibility of organic matter or flow of microbial N.
