The status of soil nutrition of 55 representative Wudang Taoism Tea gardens was analyzed and some improvement countermeasures were put forward in this study.The experiment results indicated that pH value and the content of organic matter and available N of soil in Wudang taoism tea gardens were high.The content of available P was middle and decreased with the uprising of altitude.The content of available K was low and the area of K-deficient soil was large.The content of available K increased with the altitude uprising.Based on these,some improvement approaches were put forward as follows,increasing the application of organic manure,extending the formula fertilization technique and adjusting soil pH value.
In the implementation of the national project of formula fertilizing by soil testing,the current situation of soil nutrient of the cultivated land in Shiyan city was investigated,analyzed and compared with the results of the second soil general survey in 1982.The results showed that: in comparison with the survey results of the year 1982,for the soil of Shiyan city in 2009,the content of available potassium was basically the same,the content of organic matter and alkaline nitrogen appeared a rising trend,and the content of available phosphorus increased greatly,but the pH-value decreased significantly.Otherwise,this article analyzed the reasons for the changes in soil nutrient of the cultivated land in Shiyan city,and put forward several measures for increasing soil nutrient content.
Technical research and demonstration of agricultural ecological rehabilitation along Danjiangkou reservoir covered watershed areas for the North-to-South Water Transfer Project were conducted through the State Science and Technology Support Program.Through analyzing acute contradictions in crop farming and ecological construction in Danjiangkou reservoir covered areas,contradictions being confronted in ecological construction and ecological control intervention were discussed,and countermeasures for ecological rehabilitation along Danjiangkou reservoir covered areas were put forward.
实地调查了十堰市100户农户所种植的粮食(含油菜)、蔬菜、特产作物的施肥情况,结果表明:2005年耕地有机肥在肥料总养分中所占比重下降了11.4%,氮磷钾比例为1∶0.33∶0.12。针对目前施肥上存在的问题,阐述了平衡施肥的必要性。
