上海地区‘阳光玫瑰’花果管理及配套栽培技术

Flower and fruit management and cultivation techniques of‘Shine Muscat’grape in Shanghai region

以上海地区设施栽培‘阳光玫瑰’葡萄为研究对象,对其花穗整形、植物生长调节剂的规范使用、果穗长度和留粒数等进行调查,确定了花果管理的技术规范,即在始花期将花穗留存穗尖4 cm;在落花后1~3 d内用25 mg/L GA3+2 mg/L CPPU进行保果处理;花后一周果粒黄豆大小时进行疏粒,留粒数50粒左右;落花后13~15 d内用25 mg/L GA3进行果实膨大处理。成熟时果穗质量为600 g左右,粒质量为12 g,可溶性固形物可达到18%以上,具有良好的风味和较高的商品率。同时,总结‘阳光玫瑰’葡萄的关键栽培环节,包括病虫害防治、土肥水管理等的技术要点和注意事项。

'Shine Muscat'grape was conducted as the research object in Shanghai.The cluster thinning,application of plant growth regulators,and the length of flower and cluster were investigated and determined in details.The results showed that flower should be cut to 4 cm at the beginning of flowering period,and within 1-3 days after flower falling the 25 mg/L GA3+2 mg/L CPPU was used;one week after the flower falling,the cluster was thinned and the number of berry remained was about 50;the cluster was treated with 25 mg/L GA3 within 13-15 days after flower falling.Thus,at maturity,cluster weight was about 600 g,single berry weight was 12 g,and the soluble solids could be more than 18%,which had good flavor and high commodity rate.At the same time,the key cultivation points of'Shine Muscat'grape were summarized,including disease and pest control,management of soil,fertilizer and water,etc.
