在很多人眼里,李晖是一个很另类的人。他从兰州大学核物理专业毕业,在北京拥有自己的公司,还是一家大型上市公司的股东。但突然,他跑回家乡静宁种植苹果了。他说,他要引入现代农业的先进理念和管理技术,在静宁这块最适宜种苹果的土地上,生产出全世界最优质的苹果。目前,李晖已经投资3000多万元,建成了7500亩的4个现代化苹果种植基地和一个500亩的高新苹果育苗基地。建设现代化苹果产业园种植葡萄要搭架,但您见过给苹果树也搭架的果园吗?在静宁,就有这样一块很特别的果园,它是全省第一个规模最大的现代化苹果产业园。在该县威戎镇2000亩矮砧密植现代化苹果产业 相似文献

We investigated the population density and range use of sika deer,Cervus nippon, on Mt. Ohdaigahara, central Japan, from July 1996 to July 1997. The deer population density estimated by the block count
was high at 17.5–30.9 deer/km2. Although the deer remained this area from spring to fall, they moved out in winter, probably because of deep snow. A spotlight
count showed that the deer prefer the eastern area as spring-summer range, where the forest consists of coniferous trees over
a floor cover ofSasa nipponica, andS. nipponica grassland. The deer also use dense coniferous forest for cover, especially in summer and fall.
Part of this study was presented at the 108th Annual Meeting of the Japanese Forestry Society (1997).
This study was financially supported by the Environment Agency, Japan. 相似文献

梅花鹿有较高的经济价值和药用价值,现已推广人工饲养,在人工饲养时,会遇到产仔后的母梅花鹿弃仔现象,如不及时处理,会影响仔鹿的成活率。对于这种现象发生的原因及处理措施及预防提出以下建议:1发生原因1.1梅花鹿产仔时,如有人尤其是陌生人的靠近,会产生恐惧感,会抛弃仔鹿,拒绝让仔鹿吮乳。1.2外界环境干扰,如:噪音、巨大响声等。2处理措施2.1首要方法是让仔鹿能吃上亲生母鹿的初乳,因为初乳能增强仔鹿抗病能力,且能促进胎粪的排出,让母鹿与仔鹿单独在同一个产圈内,加深对仔鹿印象,仔鹿出于本能,会接近母鹿并… 相似文献

In a large field experiment we studied the influence of regenerationmethods on the extent to which roe deer (Capreoluscapreolus L.) browse on spruce (Picea abies L.Karst) seedlings. Our objective was to evaluate if treatments that are good atstimulating regeneration may increase browsing damage by deer. Data werecollected between 1993 and 1995, and in the winters of 1993–94 and1994–95 the frequency of browsed seedlings was 13.2% and 13.4%,respectively. The frequency of browsing damage varied considerably betweensitesand clearcuts. Browsing damage was more frequent when the regeneration methodsincluded insecticide treatments. Among insecticide-free treatments, browsingwasheavier on scarified plots than on herbicide-treated or control plots (in whichseedlings were planted on untreated ground and given no post-plantingtreatment). Containerised seedlings were browsed more than bare-rooted ones.Neither the age of clearcut when planting, nor removal of slash, had any effecton browsing. It was demonstrated that regeneration methods that increased plantvigour (as assessed by leader growth and needle colour index) led to morebrowsing damage. Thus, our results support the plant vigour hypothesis, whichstates that many herbivores prefer to feed on vigorous plants because they aremore nutritious. However, the difference in browsing damage betweencontainerised and bare-rooted seedlings could not be explained solely by theplant vigour hypothesis. 相似文献

At moderate to high densities ungulates can impact negatively on forest crops and these may be managed by lethal control. In production forestry an understanding of the relationship between ungulate density, habitat-related factors and the incidence of tree damage may promote more efficient ungulate damage management than by lethal control alone. In plantation forests in the north east of England, the incidence of conifer leader browsing by roe deer (Capreolus capreolus) was positively associated with an index of deer density (at the site scale) and planted crop tree density (at the feeding patch scale) and was negatively associated with the relative abundance of palatable understorey vegetation (at the site scale). An interaction between the deer density index and palatable understorey browse abundance was positively associated with leader browsing. Coefficients from the optimal model were used to construct a browse probability surface across a matrix of values of deer dung density and palatable understorey vegetation abundance. This illustrated a very different relationship between dung density and conifer leader browsing probability across the various levels of palatable understorey vegetation abundance. From this we hypothesise that in areas of limited palatable understorey vegetation abundance, higher levels of culling may be required to achieve reductions in the incidence of conifer leader browsing than would be necessary in areas with moderate to high palatable understorey vegetation abundance. Improvements to understorey vegetation in concert with roe deer population control may enhance the efficiency of deer damage management in upland areas with nutrient-poor soils. 相似文献
