The result indicated that straw mulching could increase soil porosity by 2. 88 % - 5. 76 %, reduce soil bulk density by 1. 86 % - 3. 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage, improve water - stable aggregate ; and increase soil organic matter, available n, available p, available k, improve soil perviousness and soil retention of water and fertilizer
研究結果表明，與對照ck1 ，相比，秸稈覆蓋可使土壤總孔隙度增加2 . 88 % ~ 5 . 76 % ，土壤容重降低1 . 86 % ~ 3 . 73 % ，並且各生育期覆蓋處理的土城含水量均比對照高，並且秸稈覆蓋還田對促進土壤團粒結構形成具有較大作用，改善了土坡通透性和保水保肥性；同時秸稈覆蓋還田使土壤有機質、全氮、速效氮、速效磷、速效鉀得到明顯提高，從而培肥地力。 -
In this thesis, a new strip chopping anti - blocking mechanism and a new no - till planter operating well in heavy straw mulching condition are developed from the following aspects : ( 1 ) in order to solve the problem that the no - till planters can not work well when the mulched straw is long and thick, especially in the double cropping area of huabei plain where the winter wheat gives a high yield, a new strip chopping anti - blocking mechanism was developed. it consists of a group of rotary blades, a narrow tine opener, a shear bar, a hood and a deflector
在以下幾個方面進行了較為深入的研究： （ 1 ）在對國內外免耕播種機防堵裝置研究的基礎上，針對華北一年兩熟地區麥收后地表覆蓋量大的特點，通過對驅動式和從動式防堵裝置的對比實驗，設計出一種具有高效防堵能力的帶狀粉碎防堵裝置，該裝置由組合刀片、開溝器、定刀片、罩殼和導草扳組成。 -
On this base, a new water managemat pattern of orchard on weibei highland, “ grass planting beween apple tree rows + wheat straw mulching on the region of apple tree roots ”, was put forward
在此基礎上，提出了渭北旱地果園各種年型下「果樹行間生草+樹盤秸稈覆蓋」的水分管理新模式。 -
The results showed that the best water management pattern of fuji apple orchard was wheat straw mulching under low annual precipitation and grass planting under high annual precipitation. the comprehensive analysis was carried out on effects of different water management patters on yield of fuji apple, soil water conservation and soil organic matter of fuji apple orchard, growth in various stages and fruit quality of fuji apple under different annual precipitation
結果表明，在乾旱年份，紅富士蘋果園水分管理模式以秸稈覆蓋方式最佳，在多雨年份，紅富士蘋果園水分管理模式以果園種植白三葉草方式最佳；並綜合分析了不同降水年型不同水分管理模式對紅富士蘋果產量的影響，不同水分管理模式對果園土壤含水量和土壤有機質的影響及不同水分管理模式對紅富士蘋果生長狀況、外觀品質、內在品質的影響。 -
Through field fixed location experiment and some determinations of soil physical and chemical properties, the ameliorative effect and the crop field effect of straw mulching in hilly area of the central sichuan basin was explored
摘要通過田間定位試驗和土壤理化性質的測定，探討了秸稈覆蓋對川中丘陵區土壤的改良效果及對作物產量的影響。
