“一年之计在于春。”搞好葡萄春季萌发前的各项管理,对保证花芽的继续分化,提高芽眼萌发率,增加果枝率和结果系数,促进新梢的生长发育极为重要。因此必须周密计划,妥善安排,不违农时地做好葡萄萌发前的春施基肥、出土上架、追肥灌水、喷布铲除剂等项管理。一、春施基肥以供葡萄全年生育期对营养的要求。一般凡未进行秋施基肥的地区,春季必须根据可能条件施入一定量的基肥。时间在3月中下旬结合出土施入防寒沟,淘浅时先清沟至60厘米深施入。亩施量:自积农家肥4000～5000公斤;
“The plan of a year lies in spring.” To improve the management of grapes before spring germination is very important to ensure the continued differentiation of flower buds, increase germination rate of buds, increase the rate of fruiting branches and the result coefficient, and promote the growth and development of new shoots. Therefore, we must make a thorough plan and properly arrange the management of the spring basal fertilizer prior to the germination of grapes, the shelves excavated, the top dressing and irrigation, and the eradication agent sprayed out during the agricultural period. First, the spring base fertilizer for grapes throughout the growing period of nutrition requirements. In general, where autumn basal fertilizer is not applied, a certain amount of basal fertilizer must be applied in spring according to the possible conditions. Time in late March combined with unearthed into cold trench, scour shallow shallow ditch to 60 cm deep into. Mushi amount: since the accumulation of farm fat 4000 to 5000 kg;
