How to grow Red Rose Grape planting techniques and matters needing attention

Do we often eat grapes in our daily life? and every time we go to the fruit supermarket to buy grapes, there are many different kinds of grapes and different tastes. Some people like big grapes, some people like sweet grapes, some people like red grapes, and some people like purple grapes. Red rose grape is a small, sweet grape. If someone wants to plant one at home. Then how to grow red rose grapes?

How to grow red rose grapes

The annual branches with sturdy growth and full bud eyes are commonly used for branch propagation. Cut with single or double buds to grow about 5-15cm cuttings, cut in the seedbed according to the distance of 15cm × 50cm in February.

Planting techniques and matters needing attention of Red Rose Grape

I. planting techniques

1. Choose a garden with high topography, preferably sunny slopes, rich and deep sandy loam or loose soil, land with good irrigation and drainage by PH6.3--7.3. As grape cultivation is a labor-intensive industry with more manual operation, it is best to build a garden in a place with abundant labor.

2. To set up the support, the support can be a cement column, which is about 2.5m long, the thick 300px is square, the column distance is about 6m, and the buried depth is 60--1750px. The scaffolding mode of single column and double arms off the shelf is beneficial to the early results and high yield in the later stage.

3. Planting, choose 1-2-year-old grafted seedlings with complete root system and more fibrous roots, the optional plant spacing is 1.5m, the row spacing is 6m, and the density is small, in order to improve the ventilation and light transmittance and reduce the pathogenic factors. When the ground temperature in spring in the north reaches 7 Mueller 10 degrees, it will be planted. It is warm in winter in the south and can be planted in late autumn or winter.

II. Points for attention

The main results are as follows: 1. Different groups of red rose grape have different requirements for temperature in different growth periods.

2. Red rose grape is a water-loving plant, so we should pay attention to watering.

3. Grape is a light-loving plant, and the requirement of light has a great influence on the growth and development, yield and quality of grape.

Fertilizer and Water Management of Red Rose Grape

The main results are as follows: 1. Base fertilizer is mainly applied in ditch, and base fertilizer is applied once a year. On one side of the plant to the left and right of the trunk 40cm, the 30cm is widened and the 60cm application ditch is deep. The following year, a ditch was opened on the other side to apply base fertilizer. Fertilization begins when 60% to 70% of the leaves turn yellow and then turn yellowish.

2. Topdressing, which was carried out according to the grape growth period, was carried out before sprouting for the first time, and nitrogen fertilizer was applied as the main fertilizer, about 50g per plant. The second topdressing period is the fruit expansion period, topdressing the fruit fertilizer based on phosphorus and potassium fertilizer, mainly 0.3% potassium dihydrogen phosphate, promoting fruit expansion, flower bud differentiation and fruit ripening.

3, foliar fertilization, foliar fertilization combined with disease prevention spray before flowering, foliar spraying 0.2%-0.3% borax solution + 0.3% potassium dihydrogen phosphate.

4. Watering, watering mainly with small water during the growing period, in order to reduce the flow rate, not spread the ridge, open the upper and lower tuyere to dehumidify after irrigation, in order to prevent gas burn and disease outbreak, and planing the rake surface when the surface is white.

Ear Management of Red Rose Grape

1. According to the standard of high quality fruit, the yield of red rose grape should be controlled at about 1500-2000kg per 667m, and the fruit per ear should be kept at about 750g, that is, 1500-2000 ears per 667m. The average number of ears per main vine is 5-7 ears per 667m2, and each plant has 10-15 ears, and the extra ears can be thinned out.

2. The red rose grape goes to the accessory ear, pinches the ear tip, straightens out the ear sandwiched between the branches, and makes it droop naturally. The length of the ear is 12-15 cm, the longest is not more than 20cm, so that the whole ear is tight but not squeezed, loose but not loose.

3. Grain thinning: remove small grains, deformed grains, injured grains and fruit grains that are too tight and squeeze each other on the ear of red rose grape. In order to save labor, some spikelets on the rachis can also be removed. There are about 50 grains per panicle, and the average grain weight is 14-15g, which can guarantee about 750g per panicle.

4. Bagging, in order to ensure that the ear of Huhong rose grape is not polluted by pesticides, reduce the harm of diseases, insect pests and birds, prevent the ear and leaf from friction and damage to the fruit surface, avoid sunburn and excessive color, and prevent fruit surface from cracking and hail. after thinning, the ear should be bagged in time. Before bagging, spray Bordeaux liquid of 0.7 and 200 Bordeaux once on the ear that has been thinned. After the fruit surface is dried, put on the paper bag, fasten the upper mouth of the paper bag and fix it on the old vine, and leave a vent at the two corners of the lower mouth for ventilation. Paper bags are generally 33 cm long and 30 cm wide. Single-layer paper bags soaked with fungicides for grapes should be selected.

The red rose grape not only tastes sweet and sour, but also its meat is very solid, so if you pick or buy a lot of it, don't worry about it, because the red rose grape is not easy to go bad, so it is very good for storage. The above introduces the planting method of red rose grape. I don't know if everyone will know it.
