It is learned from Beijing Dayang Road Agricultural and Sideline Products Wholesale Market that the price of red grape is about 51.00 yuan/kg, and the price of red grape in Jinan Dikou Fruit Wholesale Market is about 16.00 yuan/kg.

When will 2018 red grapes mature?

1. The young trees of red grape grow vigorously, the young trees are easy to grow greedily, and the branches mature late. After the branches mature, the internodes are short, the bud eyes are prominent and plump, the fruiting rate is about 70%, the fruiting coefficient is 1.3, the fruit has the habit of secondary fruiting, the fruit growth period is 100 days, from germination to complete fruit maturity is 135 days, and the maturity period is slightly earlier than longan grape.

Generally, the end of May and the beginning of June are the flowering seasons of grape trees, and the mature time of grapes is different due to different varieties, and mature grapes are listed from August to October.

2018 How to grow red grapes? What are the fertilization techniques?

1) Time of planting. Autumn planting in the north is better than spring planting, but in order to protect the safety of newly planted seedlings, in the cold winter north, if irrigation is convenient, it is best to plant in spring.

2. Soil preparation before planting. Before planting, according to the row spacing (fence frame 2.5 meters, scaffolding 4.5-5 meters), dig planting trenches 1 meter wide and 0.6-0.8 meters deep. Backfill a mixture of organic matter (wheat straw, chopped corn stalks, fallen leaves, sawdust, etc.) and soil (1:1-1:2) from the bottom of the ditch to about 30 cm above the ground, followed by adequate irrigation. After the fill sinks, fill it to the ground with a mixture of decomposed manure (4000-5000 kg per mu) and soil. If the seedlings are planted in spring, the above preparations should be completed in the autumn of the previous year.

3. Select and repair each seedling before planting. For seedlings meeting quality specifications, 3-4 full buds are usually cut from the shoot, the root system is cut off and the moldy part is cut off, and the shoot is soaked with 5-degree sulfur mixture or 200 times arsenic thiram for 2-3 minutes to eliminate pathogens and pests carried on the shoots.

In the pre-prepared planting rows, dig 30×30 ×30 (cm) planting pits every 1.2 meters, add 0.3 kg urea and 0.2 kg diamine to each plant, align the seedlings into the pits, stretch the roots, step on the soil while filling, and gently lift them upward to make the roots closely contact the soil. The planting depth is suitable for 1-2 buds at the base of branches. Water thoroughly after planting. After a few days, loosen the soil and cover with plastic film (film width 0.8-1.0) to keep warm and moisture, so as to facilitate the healthy growth of seedlings in the same year.

4, to adhere to the appropriate amount of fertilizer, reasonable nitrogen application, improve the proportion of phosphorus and potassium. 5000kg of decomposed farm manure is applied per mu during soil preparation, nitrogen fertilizer is applied in growing season, foliar fertilizer is sprayed, 3% zinc sulfate is sprayed before germination, 0.3-0.5% urea and 0.2-0.3% potassium dihydrogen phosphate are sprayed in growing season. Water is poured once after each fertilization, but not too much, so as to avoid high humidity and increase the incidence rate.

5. Before planting, a large amount of farm manure and phosphate fertilizer should be applied at one time as base fertilizer, and fully decomposed manure (preferably sheep manure or chicken manure)3000 kg ~5000 kg and calcium superphosphate 150 kg can be applied per mu. Digging trenches with width and depth of 80cm along planting rows (deep soil and surface soil are stacked separately), filling a layer of straw, leaves or raw sheep dung 15~ 20cm at the bottom of the trench, then filling the deep layer with deep soil and a small amount of fertilizer, filling the surface layer with surface soil and a large amount of fertilizer, and applying calcium superphosphate to the soil layer 10~ 15cm away from the ground.

Grape seedlings after planting from the second year to apply a certain amount of base fertilizer every year. Generally, after grape harvest, a fertilizer ditch with a width of 30 cm and a depth of 60 cm shall be excavated at a position 40~50 cm away from seedlings along one side of the planting row (it can be extended outward appropriately later), and 5000 kg of fully decomposed organic fertilizer shall be applied per mu along with excavation, and 200 kg of calcium superphosphate shall be mixed and applied per mu.
