1、根區(qū)局部控水無(wú)壓地下灌溉對(duì)番茄生理特性及產(chǎn)量、品質(zhì)的影響王燕1，蔡煥杰1，陳新明1，2，鄭健1（1西北農(nóng)林科技大學(xué)水利與建筑工程學(xué)院，楊凌712100；2塔里木大學(xué)，阿拉爾市843300）摘要：【目的】探明無(wú)壓灌溉不同供水水平對(duì)作物根區(qū)土壤水分條件、番茄的形態(tài)指標(biāo)、水分生理指標(biāo)和光合生理指標(biāo)及產(chǎn)量、品質(zhì)和水分利用效率的影響?！痉椒ā恳詵|圣一號(hào)番茄為試驗(yàn)材料，在日光溫室進(jìn)行了灌溉試驗(yàn)研究，試驗(yàn)共設(shè)3個(gè)供水水平，壓力水頭分別為0、3和6cm，并采用DPS分析軟件對(duì)數(shù)據(jù)進(jìn)行了顯著性分析。【結(jié)果】不同供水水平對(duì)番茄的生長(zhǎng)發(fā)育及產(chǎn)量品
2、質(zhì)有顯著的影響。6cm處理番茄產(chǎn)量最高，3cm處理次之，0cm處理最低；但番茄的水分利用效率卻是0cm＞3cm＞6cm處理；0cm處理下番茄的糖酸比和可溶性蛋白含量最高，Vc含量降幅也不大；相對(duì)于0cm處理，6cm和3cm處理的Vc含量分別提高了19.2%和6.8%?！窘Y(jié)論】根區(qū)局部控水無(wú)壓地下灌溉能夠滿足番茄需水量，不同供水壓力對(duì)番茄根區(qū)土壤水分、生理特性和產(chǎn)量影響不同，同時(shí)能夠協(xié)調(diào)番茄糖酸之間的比例，提高番茄的糖酸比、可溶性蛋白含量和Vc含量，使番茄能更加美味可口，起到了以水調(diào)質(zhì)的功效，值得在農(nóng)業(yè)生產(chǎn)中推廣。關(guān)鍵詞：無(wú)壓
