摘　　要：为提高樱桃番茄产量,以樱桃番茄浙樱粉1号为供试作物,基于20 cm深度处土壤水势设计3种灌溉水平(-10 kPa(T1)、-30 kPa(T3)、-50 kPa(T5)),探讨了不同水分处理对樱桃番茄各穗产量、单果质量、每穗果实个数、番茄横径和番茄纵径等的影响。结果表明:T3处理番茄总产量(38.00 t/hm^(2))比T1(34.70 t/hm^(2))和T5(30.38 t/hm^(2))处理提高9.50%~25.07%。T3和T5处理单果质量、果实横径和纵径均值分别比T1处理降低8.75%和15.06%、4.05%和5.16%及2.98%和6.31%,说明番茄单个果实质量、果实横径和纵径随灌水频率降低而降低。番茄各穗产量和果实个数均以第5穗最高,其余各穗产量和果实个数分别比第5穗减少39.26%~83.02%和36.84%~81.56%;因此,T3处理可作为研究区水分调控阈值,以促进樱桃番茄增产增收。To improve the yield of cherry tomatoes,this study used the cherry tomato variety'Zheyingfen No.1'as the test crop.Based on soil water potential at a depth of 20 cm,three irrigation levels were designed:-10 kPa(T1),-30 kPa(T3),and-50 kPa(T5).The effects of different water treatments on various parameters were investigated,including yield per truss,individual fruit weight,the number of fruits per truss,tomato fruit width,and tomato fruit length.The results showed that the total yield of tomatoes under the T3 treatment(38.00 t/hm^(2))increased by 9.50%~25.07%compared to the T1(34.70 t/hm^(2))and T5(30.38 t/hm^(2))treatments.The average individual fruit weight,fruit width,and fruit length under T3 and T5treatments decreased by 8.75%and 15.06%,4.05%and 5.16%,and 2.98%and 6.31%,respectively,compared to T1,indicating that the weight,width,and length of individual fruits decreased with irrigation frequency decreasing.The yield and number of fruits per truss were highest for the fifth truss,while the yield and number of fruits for other trusses were reduced by 39.26%-83.02%and 36.84%-81.56%,respectively,compared to the fifth truss.In summary,the T3 treatment can be recommended as the water regulation threshold for the study area to promote increased yield and income of cherry tomatoes.
