摘要
针对宁夏贺兰山东麓葡萄酒地理标志产区风土特征中存在的矿质营养元素有效性低导致的产区葡萄酒特色不鲜明、风味与香气不足等问题。以6年生“赤霞珠”为研究对象,设置5个不同糖醇钙喷施水平:1.2 L·hm^(-2)(T1)、2.4 L·hm^(-2)(T2)、3.6 L·hm^(-2)(T3)、4.8 L·hm^(-2)(T4)和6.0 L·hm^(-2)(T5),以喷清水为对照(CK),研究叶面补施糖醇钙对酿酒葡萄品质及产量的影响。结果表明,叶面喷施糖醇钙处理的穗长、百粒重、产量、单宁、总酚、产投比均较CK显著增加且以T2处理最高,T2处理的穗长、百粒重、产量、单宁、总酚、产投比分别较其他喷施糖醇钙处理增加3.96%~17.49%、9.54%~16.62%、5.48%~23.59%、8.96%~21.12%、4.51%~13.54%、6.98%~20.00%;横径、纵径、果型指数以T3处理最高,分别较其他喷施糖醇钙处理增加1.71%~10.50%、5.33%~23.64%、3.92%~7.07%;果实可溶性固形物、花色苷以T4处理最高,分别较CK提高5.86%和43.24%,分别较其他喷施糖醇钙处理增加2.07%~5.58%、15.22%~29.27%;可滴定酸以T2处理最低,叶面补施糖醇钙处理较CK降幅为6.49%~28.33%。总之,在贺兰山东麓葡萄酒产区通过叶面补钙肥能有效促进酿酒葡萄浆果品质的提升,叶面喷施糖醇钙量控制在2.4 L·hm^(-2)左右时对酿酒葡萄的产量和品质提升效果最优。
Aiming at the problems in the terroir characteristics of Ningxia Helan Mountain wine producing area,such as the lack of distinct characteristics,flavor and aroma due to the poor availability of mineral nutrients,etc.,taking 6-yearold“Cabernet Sauvignon”as the object of study,5 different levels of calcium gluconate spraying were set up:1.2 L·hm^(-2)(T1),2.4 L·hm^(-2)(T2),3.6 L·hm^(-2)(T3),4.8 L·hm^(-2)(T4)and 6.0 L·hm^(-2)(T5),and water spraying was used as the control group(CK)to study the effects of foliar calcium gluconate spraying on the quality and yield of wine grapes.Results showed that comparing with CK,the spike length,hundred grain weight,yield,tannin,total phenol and input-output ratio of foliar calcium gluconate spraying treatment increased significantly and T2 treatment was the highest,the ear length,hundred grain weight,yield,tannin and total phenol,input-output ratio of T2 treatment,compared with other spraying calcium gluconate treatment,increased by 3.96%~17.49%,9.54%~16.62%,5.48%~23.59%,8.96%~21.12%,4.51%~13.54%and 6.98%~20.00%,respectively.The indexes of transverse diameter,longitudinal diameter and fruit type were the highest in T3 treatment,which increased by 1.71%~10.50%,5.33%~23.64%and 3.92%~7.07%,respectively,compared with other treatments.The soluble solids and anthocyanins were the highest in T4 treatment,with an increase of 5.86%and 43.24%,respectively,compared with CK treatment,and an increase of 2.07%~5.58%and 15.22%~29.27%,respectively,compared with other treatments.The titrable acid was the lowest in T2 treatment,and the decrease range of leaves sprayed with calcium gluconate was 6.49%~28.33%compared with CK treatment.In short,in the wine producing areas at the eastern foot of Helan Mountain,the leaves were sprayed with calcium gluconate could effectively promote the improvement of grape berry quality,and the optimal effect was achieved when the amount of calcium gluconate sprayed on the foliar was controlled at about 2.4 L·hm^(-2).
