Factors effecting the degradation rate, including types of light sources, photooxidation catalyzers and sensitizers, the pH value of water and the component of humus were investigated in the experiment, and the treatment of wastewater containing triazophos using UV-Fenton was also studied in this paper.
为此本文进行了三唑磷在水体中光降解的实验研究,考察了光源、光催化剂及光敏剂、水体pH值、腐殖质成分等因素对三唑磷光降解的影响,并对UV-Fenton处理三唑磷废水进行了研究。

So,obviously,the Ca and P level of group Ⅰ diet couldnt meet the nutritinonal requirement of fattening egg-type cockerels.
试Ⅱ组和CK组比较,采食量和料重比分别降低3.78%和4.03%,差异均显著(P<0.05),日增重和经济效益分别提高0.24%和0.46%,试Ⅱ组的经济效益和CK组接近,但日粮中加入植酸酶后,减少了粪便磷排泄量,有利于控制环境污染,因此育肥蛋公雏宜采用低钙磷加植酸酶日粮。

The results showed that a combined application of manure and chemical NPK and long-term fallowing increased the contents of soil organic matter, total N, and mineralized N, as well as the N mineralization rate significantly, compared with the control.
结果表明:氮磷钾化肥和有机肥配施及长期撂荒处理显著提高了土壤有机质和全氮含量以及土壤氮素矿化量和矿化率;氮磷钾化肥处理虽然提高了土壤无机氮含量,但对土壤有机质、全氮、土壤氮素矿化量和矿化率的影响相对较小。

On the other hand, fertilizer of CaHPCu is cheap and the high degree of purity (the content of P_2O_5 is 27 -30%)can improve phosphorus in soil, reduce production cost and promotes agricultural effectiveness. The content P in CaHPO_4 slow release in calcareous soil. Besides, the addition of HA activates phosphorus in CaHPO_4 and in soil, increases organics in soil, which promotes crops quality and yield.
一方面由于磷酸氢钙的纯度高,与过磷酸钙相比重金属等杂质含量较少,能有效减少对土壤及水体的污染;另一方面磷酸氢钙价格低廉,P_2O_5,含量可以达到27~30%,在石灰性土壤中本身就是一种缓效磷;腐植酸的添加,活化了磷酸氢钙中的枸溶磷,同时可能改善了土壤团粒结构,为作物优质、高产奠定了良好的基础。
-
Accumulating of phosphorus and long-term applying organic fertilizer were leading factors of making phosphorus move downward.
磷素在土壤中的积累和长期施用有机肥是导致土壤磷素向下层移动的主要因素。
-
Our study suggests that in order to achieve high crop yields, the long-term P input-output balance, soil P supplying capacity, and yield targets should be considered when making P fertilizer recommendations and developing strategies for intensively managed wheat-maize cropping systems.
我们的研究结果表明在小麦-玉米轮作系统中为获得更高的作物产量,当做磷肥推荐和制定措施时,应充分考虑作物目标产量、磷肥效率、长期土壤磷平衡以及土壤有效磷临界值。
