    摘要:

    為確定南疆棗園切根撫育作業(yè)工藝,,測(cè)定了棗園土壤含水率,、堅(jiān)實(shí)度、孔隙度,、容重,、粒徑分布等物理參數(shù),統(tǒng)計(jì)了棗園待切根區(qū)的根系聚集深度、土壤含根量等,,確定了切根區(qū)位置為距樹干750mm和切根作業(yè)深度應(yīng)在0~200mm范圍內(nèi)可調(diào)的農(nóng)業(yè)技術(shù)要求,。研究結(jié)果表明,根土復(fù)合體具有各向異性,,取樣角θ為0°,、45°、90°時(shí),,根土復(fù)合體抗剪強(qiáng)度T關(guān)系為T0°<T45°<T90°。為分析根土復(fù)合體產(chǎn)生各向異性現(xiàn)象的原因,,采用掃描電鏡(SEM)獲取了根土復(fù)合體在不同取樣方向上的微觀結(jié)構(gòu)圖像,,通過PCAS軟件處理并獲取了根土復(fù)合體微觀結(jié)構(gòu)參數(shù)。將根土復(fù)合體的宏觀圖像,、微觀圖像,、微觀結(jié)構(gòu)參數(shù)、抗剪強(qiáng)度參數(shù)結(jié)合,,定性和定量分析了根土復(fù)合體產(chǎn)生各向異性的原因及規(guī)律,,得到微觀結(jié)構(gòu)參數(shù)與抗剪切強(qiáng)度相關(guān)性由強(qiáng)到弱依次為孔隙概率熵、孔隙形態(tài)分維數(shù),、顆粒形狀系數(shù),、孔隙形狀系數(shù)、顆粒概率熵,、顆粒形態(tài)分維數(shù),。根據(jù)研究結(jié)果提出根土復(fù)合體抗剪強(qiáng)度測(cè)定時(shí),環(huán)刀應(yīng)垂直于耕作過程產(chǎn)生的實(shí)際剪切發(fā)生面方向取樣,。本研究可為棗園切根撫育機(jī)具設(shè)計(jì)和研發(fā)提供理論依據(jù),,為土壤耕作類部件優(yōu)化設(shè)計(jì)、耕作類部件與土壤相互作用關(guān)系等研究提供參考,。

    Abstract:

    To determine the operation technology of root cutting and nurturing in jujube orchards in southern Xinjiang, physical parameters such as soil moisture content, solidity, porosity, bulk density, and particle size distribution were measured. The root aggregation depth and soil root content of the jujube orchard’s root cutting area were also calculated. The agricultural technical requirements were determined that the root cutting area should be located 750mm away from the tree trunk and the depth of the root cutting operation should be adjustable within the range of 0~200mm.The research results indicated that the root soil composite had anisotropy. When the sampling angles θ were 0°, 45° and 90°, the shear strength T relationship of the root soil composite showed trend of T0°
