南方葡萄园土壤肥力障碍因子主要是质地粘重,酸性强,有机质和磷、钾养分不足.高畦深沟栽培,使土壤通气状况得到改善.有效降低土壤和架面空间温度,促进土壤养分有效化,增强树体抗病力,增产效果显著.酸性土壤pH调节至6左右,根系分布范围扩大47%,有利根系吸收养分.粘质土壤施用垃圾可改善土壤通透条件,叶片发病率下降3%-9%.适宜的磷钾配比,使叶片发病率下降8.1%,果穗发病率下降19.2%,浆果可溶性固形物增加2.1%.
Soil fertility barriers in the southern vineyard are mainly sticky texture, strong acidity, organic matter and phosphorus, potassium nutrient shortage .Highland deep-groove cultivation, so that the soil aeration conditions have been improved effectively reduce soil and shelf space temperature, and promote soil nutrient effectiveness , Enhance tree disease resistance, increase yield significantly.Acid soil pH adjusted to about 6, the root distribution of 47% widened, beneficial root absorption of nutrients.Clay soil application of trash can improve the soil permeability, the incidence of leaves decreased by 3% -9% .Appropriate phosphorus and potassium ratio decreased the incidence of leaf 8.1%, ear morbidity decreased 19.2%, berry soluble solids increased 2.1%.
