中文拼音 [bǎnjiēdetǔrǎng]
板結的土壤
英文
hardened and impervious soil-
With the development of human society, because of the lack of sustainable utilization consciousness, and the eager for quick success and instant benefit, the black earth suffered excessive cultivation and management, causing the reduction of its recycled ability, decrease in organic content, porosity ratio, fertility dropped and the properties of water retaining and water retention, which make the black soil harden and degenerate seriously
但是隨著人類社會的發展，在缺乏保護和可持續利用意識、急功近利思想影響下，黑土遭到過度墾殖和掠奪式經營，人類對其活動范圍遠遠超過了其再生能力，導致有機質含量減少，肥力下降，孔隙比減小，保水持水能力降低，土壤板結，黑土嚴重退化。A compact soil has little insulating effect.
板結的土壤幾乎沒有隔熱作用。The results are summarized below : 1 ) study on soil science indicates that soil granular structure is the focus adjuster for soil fertility and it affects the space, water - grasp, aeration and anti - erosion of soil. and the percentage of aggregate is one of the key index that decides the speed and extent of soil erosion, hardening and degeneration because the soil degeneration will first lead to the disappearance of crumb - structure. so it is very important that the physical course and character of soil in different land use pattern are realized
現將主要結果摘要如下： l 、士壤學研究表明，團粒結構是土壤肥力的中心調節器，影響著土壤的空隙性、持水性、通透性和抗蝕性；任何土壤的退化首先將表現出團粒結構的消失；團聚體百分比是決定土壤侵蝕、板結等物理過程速度和幅度的關鍵指標之一，了解不同土地利用和土壤管理方式的物理過程和性質相當重要。Soil reinforcement. backfilled structures reinforced with quasi - inextensible and flexible reinforcing strips or sheets. static pull - out test with constant rate of displacement

黑土是我國的主要耕作土壤，目前隨著土地的開發，一些地區土壤結構破壞，板結嚴重，黑土層變薄，地力減退。Standard test method for capillary - moisture relationships for coarse - and medium - textured soils by porous - plate apparatus
用多孔板儀器測量粗粒和中等結構土壤的毛細管與水份關系的標準試驗方法After rain, the soil water content is higher, while no rain, the soil water content decreases faster relatively. in autumn, the soil water content begins to drop, but the drop range is small than summer. during continual d rought, the soil water content of surface layer approaches to that of middle layer and under layer ; water conservation measures can increase chestnut ' s new branch remarkably, results difference among water conservation measures are not significant, meanwhile, water cons
而在持續乾旱期，表層土壤的含水量接近於中下層土壤的含水量;保水措施能使新梢明顯增長，而保水措施之間的效果差異不明顯;同時保水措施並不能使新梢直徑明顯增粗;保水措施對成齡板栗樹根莖地徑的增粗生長影響不大;綜合以上試驗結果，秸稈覆蓋為太行山片麻巖區的最佳的保水措施，地膜覆蓋其次。As a part of the sino - australian project " aciar 961 / 143 sustainable mechanized dry - land grain production ", this thesis is to study mechanism and influence factors of ground wheel slide. firstly, testing method of ground wheel slide is designed
通過對地輪作業時的受力情況進行分析，得出土壤性能和地輪的結構參數如輪寬b 、垂直載荷g 、抓地板高度h等是影響地輪滑移的的主要因素。Factors which influence field soil water infiltration characteristics have soil structure, soil moisture, soil texture, topsoil crusting and plate, agriculture husbandry measure and soil water phase change and so on
影響大田土壤水分入滲特性的因素有：土壤結構、土壤含水量、土壤質地、表土結皮和板結、農業耕作措施和土壤水的相變等。分享友人
