straw mulch 中文意思是什麼
straw mulch
解釋
草蓋-
The results indicated : ( 1 ) during the jointing stage of winter wheat, the differences of catalase activity among different measures of soil water utilization are significant in shallow soil, in which the catalase activity of furrow planting with straw mulch is the highest and that of row - spacing - reduced and close planting is the lowest ; ( 2 ) the trends of catalase activity versus depth are almost the same for different treatments, looking like an inverse s ; ( 3 ) for furrow growing without mulch, the activity of soil catalase in the furrow is higher than that in the ridge ; ( 4 ) soil catalase activity reflects some effects from different techniques of soil water utilization and may be used as a indicator for micro - eco - environment in the fields
初步分析得出： （ 1 ）冬小麥拔節期，採用不同土壤水利用技術的冬小麥田淺層土壤過氧化氫酶活性差異明顯，以溝播不蓋秸稈處理的過氧化氫酶活性最強，縮行密植處理的最弱； （ 2 ）土壤過氧化氫酶活性隨深度的變化趨勢大體一致，呈反s形； （ 3 ）溝播不蓋秸稈處理溝中土壤過氧化氫酶活性明顯高於壟上； （ 4 ）土壤過氧化氫酶對於田間微生態環境具有指示作用，在一定程度上反映了土壤水利用技術對微生態環境的影響。 -
Results showed that by using straw and plastic film dual mulch in dry - cultivation of rice planting, both of the range of temperature difference and the loss of water in dry - cultivated field of rice were decreased, the soil structure was improved, the soil nutrient contents were increased, the ineffective tillers of rice plant were decreased, the growth and development stage were advanced, the filling stage was extended, the grain per ear and 1 000 grain weight were raised, the grain yield of rice increased obviously
水稻秸稈+地膜二元覆蓋旱作栽培效應的研究結果表明，秸稈+地膜二元覆蓋旱作稻田土壤變溫幅度降低，水分散失減少，結構改善，養分積累增加；水稻無效分蘗減少，生育轉變提前，灌漿結實期延長，穗大粒多，千粒重高，增產效果顯著。 -

Any organic matter can be used such as sugar cane mulch ( looks like straw ) ; hays like lucerne, oats or barley ; finely ground bark ; lawn clippings and leaves ( always mixed so they break down and don ' t actually repel water ) ; sawdust ; manures - even old clothing or newspaper can be recycled to conserve moisture
覆蓋物可選用任何有機物質，比如甘蔗桿（看起來很像麥桿） 、乾草（如紫花苜蓿） 、燕麥桿、大麥桿、碎樹皮、剪草機剪下的草、樹葉（將它們混合起來以免排斥水分） 、鋸末、肥料，甚至舊衣服、報紙等等，都可用來保持濕度。 -
The technique of water conservation in gneiss area of tai - hang mountain : on the facet of water conservation measure, four sorts of water conservation measures can all improve the soil water content. the result of straw mulch is best, using water holding agent in soil and plastic mulch are better, stone mulch is worse. four sorts of water conservation measures all improve the physical character of surface layer soil
太行山片麻巖區保水技術：在保水措施方面：四種保水措施均能提高土壤含水量，秸稈覆蓋的效果最好，土施保水劑和地膜覆蓋的效果其次，石塊覆蓋的效果較差；四種保水措施使表層土壤的物理性狀均有一定改善，使土壤容重降低、孔隙度和土壤飽和含水量增加。 -
