摘要
怀化是湖南省猕猴桃主产区,2022年夏秋连旱100 d以上,猕猴桃普遍受旱,严重减产。本文在湖南省怀化市2个猕猴桃主产县开展该区域土壤水分、猕猴桃光合作用、农艺性状和产量等指标的调查。结果表明:中方县黄岩点未受干旱情况下猕猴桃平均产量为1607.0 kg/hm^(2),重度干旱状况下平均产量为93.0 kg/hm^(2);溆浦县龙庄湾点未受干旱情况下猕猴桃平均产量为3075.8 kg/hm^(2),重度干旱状况下平均产量为971.2 kg/hm^(2)。未受干旱的猕猴桃平均产量比较,溆浦县龙庄湾点>中方县黄岩点;重度干旱状况下的猕猴桃平均产量比较,溆浦县龙庄湾点>中方县黄岩点。相同地区不同干旱程度下的平均产量,与未受干旱的产量相比,中方县黄岩点轻度干旱产量减少约48%,中度干旱产量减少约91%,重度干旱产量减少约94%;溆浦县龙庄湾点轻度干旱产量减少约17%,中度干旱产量减少约41%,重度干旱产量减少约68%;整体而言,干旱程度越严重减产越多。
Huaihua City is the main production area of kiwifruit in Hunan Province.In the summer and autumn of 2022,there was continuous drought for more than 100 days,causing widespread drought and severe reduction in kiwifruit production.This paper conducted a survey on soil moisture,photosynthesis,agronomic traits,and yield of kiwifruit in two main kiwifruit producing counties in Huaihua City,Hunan Province.The results showed that the average yield of kiwifruit at Huangyan site in Zhongfang County was 1607.0 kg/hm^(2) under non drought condition,and 93.0 kg/hm^(2) under severe drought condition;the average yield of kiwifruit at Longzhuangwan site in Xupu County was 3075.8 kg/hm^(2) under non drought condition,and 971.2 kg/hm^(2) under severe drought condition.Under non drought condition,the average yield of kiwifruit at Longzhuangwan site in Xupu County was higher than that at Huangyan site in Zhongfang County;Under severe drought condition,the average yield of kiwifruit at Longzhuangwan site in Xupu County was higher than that at Huangyan site in Zhongfang County.The average yield under different drought degrees in the same region showed that,compared with the non drought yield,the mild drought yield of Huangyan site in Zhongfang County decreased by about 48%,the moderate drought yield decreased by about 91%,and the severe drought yield decreased by about 94%;the mild drought yield of Longzhuangwan site in Xupu County decreased by about 17%,the moderate drought decreased by about 41%,and the severe drought yield decreased by about 68%;overall,the more severe the drought,the more production reduced.
