我场地处滨海盐碱地区,土壤属粘质氯化物盐代潮土,PH8.3左右,含盐量0.38％左右,地下水80～140厘米,年平均气温13.14℃,年降雨量550毫米,常年春秋干旱多风。据此,我场根据当地土壤及气候条件,结合葡萄适应性于1987年直插建园1200亩,主栽品种为玫瑰香。经过系列配套管理,收效良好。但随着葡萄树龄的逐年加大,一些园的葡萄开始出现植株衰弱老化,产量降低,品质明显下降,加之近两年来葡萄销售价格太低,销势不畅,严重影响了葡萄园经济效益,也制约着我场种植业结构调整和两高一优农业的发展进程,鉴于此自1997年我场为维持葡萄生产的健康发展,适应市场经
My site is located in coastal saline-alkali soil, soil is a clay chloride salt on behalf of the Chao soil, about PH8.3, salt content of about 0.38%, groundwater 80 ~ 140 cm, the annual average temperature of 13.14 ℃, the annual rainfall of 550 mm, perennial Spring Arid and windy. Accordingly, my field according to the local soil and climatic conditions, combined with grape adaptability in 1987, 1,200 acres into the park, the main varieties of rose incense. After a series of supporting management, effective. However, with the increase of the vine age, the grapes in some gardens began to age and weakened, the yield decreased and the quality remarkably decreased. In addition, the sales price of the grape in the past two years was too low and the sales potential was sluggish, which seriously affected the economic benefits of the vineyard. Restricting the adjustment of planting structure in our farm and the development of two high and one superior agriculture, in view of this, in order to maintain the healthy development of grape production in 1997,
