Greenhouse viticulture technology belongs to seasonal production. It is a kind of high-input, high-yield and high-benefit production. It has the ability to raise accumulated temperature. It is a kind of advanced and late-season matured off-season planting technology. It enters the market in the off-season and meets people's needs. Demand, to achieve high economic efficiency of about 40,000 per acre. One, site preparation The requirement of the soil for the grapes is that the sandy loam is better. This kind of soil has high organic matter content, deep soil, loose, fertile, good ventilation, strong water retention, and smooth drainage. Clay loam soil formula: 1/3 soil, 1/3 farmyard fertilizer, 1/3 sand and furnace ash mixture. Sandy soil formula: 1/3 soil, 1/3 farmyard fertilizer, 1/3 sand, plant ash and stove ash mixture.

In fact, watering thoroughly. Third, control the temperature According to the different requirements of the temperature of the grape growing period, effective temperature control. Germination period: 15-20C during the day, 5-10C during the night; Third week: 15-20C during the day, around 5-10C at night; Bud to flowering period: 20-25C during the day, 15-22C during the night; Flowering period: 25-28C during the day , night 18-22C; fruit expansion period: 28-30C during the day, 18-22C at night; into the berry mature period: 18-30C during the day, the highest not more than 32C, 15-16C at night; method used: cover the film, buckle small Arch sheds, ventilation, closing the shed doors and other methods to regulate temperature.
