Red Globe Grape 2018 Market Prices, Ripening and Harvesting, Planting and Fertilization Techniques
Red Globe grape, also known as Red Globe, is a Eurasian species. Originally from California, USA, its fruit is of excellent quality, late-ripening, tolerant of storage and transport, and high-yielding, making it the preferred high-quality, efficient variety for grape growing. What is the 2018 Red Globe grape market price per jin? When does it ripen and reach the market? How is it grown? What are the fertilization techniques? According to the Beijing Dayanglu Agricultural and Sideline Products Wholesale Market, the price of Red Globe grapes is around 51.00 yuan/kg, and at the Jinan Dikou Fruit Wholesale Market the price of Red Globe grapes is around 16.00 yuan/kg.
When do 2018 Red Globe grapes ripen and reach the market?
1. Young Red Globe grape trees grow vigorously, and young trees tend to keep growing late into the season, so their canes mature relatively late. After the canes mature, the internodes are short, the buds are prominent and plump, the fruiting rate is about 70%, the fruiting coefficient is 1.3, and it has a habit of a second crop; the fruit development period is 100 days, and from bud break to full fruit maturity is 135 days, with the ripening period slightly earlier than that of Longan grapes.
2. Generally, late May to early June each year is the season when grapevines bloom, and because grape varieties differ, their ripening times also differ; ripe grapes reach the market from August to October.
How are 2018 Red Globe grapes grown? What are the fertilization techniques?
1. Planting time. In the north, autumn planting is better than spring planting, but to protect the safety of newly planted seedlings, in the cold northern winters, if irrigation is convenient, spring planting is best.
2. Soil preparation before planting. Before planting, according to the row spacing (2.5 m for trellis, 4.5—5 m for pergola), dig planting trenches 1 m wide and 0.6—0.8 m deep. From the bottom of the trench up to about 30 cm from the ground, backfill a mixture of organic matter (wheat straw, chopped corn stalks, fallen leaves, sawdust, etc.) and soil (at 1:1—1:2), then irrigate thoroughly. After the fill soil settles, fill level to the ground with a mixture of decomposed barnyard manure (4000—5000 kg per mu) and soil. If planting seedlings in spring, the above preparatory work should preferably be completed in the previous autumn.
3. Before planting, each seedling must be selected and trimmed. Seedlings that meet the quality specifications usually have the aboveground part cut back to leave 3—4 plump buds, the root system trimmed of split and moldy parts, and the aboveground canes dipped in 5-degree lime sulfur mixture or 200-fold Formic arsenic for 2—3 minutes to eliminate pathogens and pests carried on the canes and buds.
In the previously prepared planting row, dig a planting hole 30×30×30 (cm) every 1.2 m, add 0.3 kg of urea and 0.2 kg of diammonium per plant; after the seedling is placed in the hole, align it with the row direction, spread out the roots, fill soil while treading it down, and lift it gently upward so that the roots contact the soil closely. The planting depth should be such that 1—2 buds at the base of the cane are buried in the soil. After planting, water thoroughly. After a few days, loosen the soil and cover with plastic film (film width 0.8—1.0) to retain warmth and moisture, so as to help the young seedlings grow vigorously that year.
4. Persist in applying generous but moderate fertilizer, applying nitrogen reasonably, and increasing the proportion of phosphorus and potassium. When preparing the land, apply 5000 kg of decomposed farmyard manure per mu, and apply nitrogen fertilizer as a top dressing during the growing season; for foliar spraying, spray 3% zinc sulfate before bud break; during the growing season, spray 0.3-0.5% urea and 0.2-0.3% monopotassium phosphate. After each fertilization, water once, but not too much, to avoid high humidity that increases disease incidence.
5. Before planting, a large amount of farmyard manure and phosphate fertilizer should be applied at one time as base fertilizer; per mu, 3000 kg to 5000 kg of fully decomposed barnyard manure (preferably sheep or chicken manure) and 150 kg of superphosphate can be applied. Along the planting row, dig a trench 80 cm wide and 80 cm deep (piling deep soil and topsoil separately); first place a 15-20 cm layer of straw, leaves, or fresh sheep manure, etc. at the bottom of the trench, then fill the deep layer with deep soil and a small amount of fertilizer, and fill the surface layer with topsoil and a large amount of fertilizer, with the superphosphate concentrated in the soil layer 10-15 cm from the ground.
After the grape seedlings are planted, a certain amount of base fertilizer must also be applied each year starting from the second year. Generally, after the grapes are harvested, along one side of the planting row at a distance of 40-50 cm from the seedlings (which can later be extended outward as appropriate), dig a fertilization trench 30 cm wide and 60 cm deep, and as you dig, apply 5000 kg per mu of fully decomposed organic fertilizer mixed with 200 kg per mu of superphosphate.
