东北寒冷地区温室果菜需水量及需水规律研究的中期报告摘要：本研究对东北寒冷地区温室中番茄、黄瓜、辣椒等9种作物进行了水分需求量及其规律的研究。通过对温室内土壤含水量、作物叶片水势及蒸腾速率等指标的测定，得出了不同作物对水的要求及其生长发育的水分需求规律。研究发现，温室中番茄、黄瓜、辣椒等作物的水分需求量较大，其中番茄需水最多，其次为黄瓜和辣椒。同时，随着温度升高和光照增强，作物对水的需求量也会相应增加。掌握温室作物的水分需求及其规律，对提高温室作物的生产效益和节约水资源具有重要意义。关键词：东北寒冷地区；温室；作物；水分需求；规律Abstract:Thisstudyinvestigatedthewaterrequirementsandthelawsofwaterdemandfor9kindsofcropssuchastomatoes,cucumbers,andpeppersingreenhouseinthecoldregionsofNortheastChina.Bymeasuringthesoilmoisturecontent,leafwaterpotential,andtranspirationrateofcropsinthegreenhouse,thewaterrequirementsofdifferentcropsandtheirlawsofwaterdemandforgrowthanddevelopmentwereobtained.Thestudyfoundthattomatoes,cucumbers,peppers,andothercropsinthegreenhousehaverelativelyhighwaterrequirements,withtomatoesrequiringthemostwater,followedbycucumbersandpeppers.Atthesametime,astemperatureincreasesandlightintensityenhances,thewaterdemandofcropswillalsoincreasecorrespondingly.Masteringthewaterrequirementsandlawsofgreenhousecropsisofgreatsignificanceforimprovingtheproductionefficiencyofgreenhousecropsandconservingwaterresources.Keywords:NortheastChina;greenhouse;crops;waterdemand;laws
