Study On The Supplemental Irrigation And Harvested Rainwater Of Apricot In Middle-Mountain Of Limestone Soil In Eastern South Shanxi

Jindongnan mountain forests in the mountains of China's major types of agriculture,forestry,business model.Determine the economic forest production factor of the main constraints is to solve the low mountain forests of the key production,but also for the selection of the optimal supplementary irrigation technology to provide a reference model.At the same time to deal with supplementary irrigation in different conditions,the dynamic changes of soil moisture for the breakthrough point,to carry out the soil moisture content distribution at different time and research,to find out the movement of soil moisture,consumption pattern is Apricot supplementary irrigation schemes in sub layer of soil an important basis for the selected depth;to forest growth and reproduction of a number of botanical indicators of different conditions to deal with supplementary irrigation in dry forests,branches,roots, leaves,shoots,flowers,fruits and the results of spot checks carried out by analysis,is initially set the supplementary irrigation of forest soil moisture an important basis for the compensation point.These studies on the economic forest of supplementary irrigation and supplementary irrigation quota system is crucial choice is the excellent choice of supplementary irrigation techniques taught the theoretical basis for models,but also has strong practical significance.Liu village in Shanxi Province as the research object Apricot slope to line orthogonal design,as compared to study the positioning observation methods,the allocation of resources for the rain,as well as dealing with supplementary irrigation in different forests of the Apricot soil moisture,as well as the growth of forest growth,reproductive research and analysis,combined with the theory of non-sufficient irrigation,harvesting of forest Apricot appropriate supplementary irrigation and supplementary irrigation during the irrigation system.The results show that:slope of soil fertility,soil moisture is better than the sunny,sunny slope is superior to light conditions.Apricot production in different aspect of the main differences from the differences in light conditions.Experimental study in the three factors,the impact of light for South Africa and China Jinzhong mountain Apricot primary factor production.Apricot forest seasonal dynamics of soil moisture changes in general can be divided into three periods:the spring soil moisture running period(that is,rapid evaporation of soil moisture phase,4 in early-early June),summer soil moisture by a view(that is,soil moisture recovery phase,in early June to early 10),as well as the slow evaporation of soil moisture squaring stage(early October-late November) period 3.Test Apricot vertical forest dynamic change of soil moisture in general can be divided into two levels: Apricot forest standard deviation of soil moisture content of soil 2＞,in order to speed changes of soil moisture level,soil depth of about 0-20cm;2＞Apricot forest soil soil moisture standard deviation 1.5＞for the active layer of soil moisture,soil depth of about 20-50cm.07-2008 Apricot forest supplementary irrigation in the three different treatment and control of soil water stress experiment,Apricot forest floor and the underground sections of the biological part of both the decrease to varying degrees,but with the level,of water deficit intensifies,the ground to reduce the magnitude of some of the more underground sections of major.07-2008 Apricot forests to deal with different supplementary irrigation shoot growth,leaf area,the standard leaves the area of production control are greater than that to deal with supplementary irrigation can significantly promote the growth of shoots.At the same time,the control and treatment of ApricotⅠvalue of the indicators is similar to,and the processingⅠ,Ⅲdeal is similar to the indicator values and significantly higher than the control and treatmentⅠ.Combination of soil moisture,and supplementary irrigation to deal with different indicators Apricot botany to identify in early April and early May for supplementary irrigation Apricot important period of economic forest,water fixed to 58mm,the supplementary irrigation time,irrigation quota 116mm.
