【摘要】：選取新疆小白杏Prunus armeniaca為研究對象,在新疆吐魯番亞爾鄉(xiāng)布設(shè)覆蓋全生物降解膜與無膜試驗區(qū),對比分析兩試驗區(qū)杏樹4-6月生長期土壤水分、溫度、養(yǎng)分及杏樹生長(基徑、新梢、葉)的差異性,并探討了覆膜調(diào)溫保墑的作用機(jī)制,結(jié)果表明:(1)與無膜區(qū)相比,4-6月份覆膜區(qū)0H≤20 cm、20 cmH≤40 cm及40 cmH≤60 cm平均可分別提高3.3%、7.08%、12.6%;4月份0H≤60 cm土壤溫度平均提高1.5℃,可顯著降低高溫期5月份0H≤20 cm土層土壤溫度,對同為高溫期的6月份也有一定的降溫作用;覆膜可促進(jìn)土壤肥力的提升,但試驗區(qū)土壤仍較為貧瘠。(2)覆膜可顯著促進(jìn)杏樹的生長,覆膜區(qū)Ⅰ、Ⅱ、Ⅲ徑級平均基徑分別顯著增加了11.86%、9.84%、11.80%,百葉質(zhì)量分別增加了111.69%、5.11%、17.56%,平均葉面長≥6 cm,平均葉面寬≥4 cm,杏樹徑級越小,覆膜對杏樹新梢的影響越明顯。(3)全生物降解膜對土壤水分、溫度的綜合作用使得覆膜具有良好的調(diào)溫保墑功能,同時促進(jìn)杏樹的生長。綜上,在新疆杏樹的栽培生產(chǎn)中可將覆膜技術(shù)進(jìn)行推廣應(yīng)用,從而有效提高區(qū)域水資源利用率及農(nóng)業(yè)生產(chǎn)效率。
[Abstract]:Xinjiang small white apricot (Prunus armeniaca) was selected as the research object. In Yar Township, Turpan, Xinjiang, the total biodegradable film and no-film test area were set up. The soil moisture, temperature, nutrient and growth (basal diameter) of apricot in the growing period of April to June in the two experimental areas were compared and analyzed. The differences of new shoots and leaves were discussed, and the mechanism of film mulching, temperature regulation and moisture conservation was also discussed. The results showed that the average soil temperature of 0 H 鈮，
