Planting technique of Tenglun Grape

Fujiminori grape is a mid-precocious grape variety, its fruit is very large, as big as table tennis, good fruit coloring, many fruit juices, deeply loved by consumers. So how to grow Fujiminori grapes? Let's get to know it with the editor.

1. Build a garden

Fujiminori grape has wide adaptability, lax requirements for soil, high yield and large fruit, so it needs a lot of nutrients in the whole growing period. the garden should choose the place with flat terrain, convenient drainage and irrigation, strong permeability, strong water and fertility conservation and sufficient light, preferably sandy loam. When building the garden, the north-south direction should be adopted, and the close planting should be reasonable. Generally, the plant spacing should be 1.2m and 2m, and the planting ditch should be dug before planting, and then the farm manure and crushed straw weeds and soil should be mixed together and filled into the ditch. 2500-3000 kg per mu is generally applied and watered after filling, and it can be planted after a week.

2. Scientific fertilization

We should increase the application amount of organic fertilizer, match chemical fertilizer reasonably, change the traditional habit of single application of nitrogen fertilizer, and implement formula fertilization. Base fertilizer was applied before and after grape harvest to promote tree potential recovery, mainly farm manure, 25-50 kg per young tree and 250 kg per 100 kg fruit tree. Topdressing is distributed in the budding stage and after falling flowers, and it is applied 3-5 times before coloring. The young trees generally apply 17 kg of nitrogen fertilizer, 8 kg of phosphate fertilizer and 8 kg of potassium fertilizer per mu, while the fruiting trees apply 34 kg of nitrogen fertilizer, 25 kg of phosphorus fertilizer and 34 kg of potassium fertilizer per mu. Urea and potassium dihydrogen phosphate were sprayed 4-6 times before flowering, after falling flower, young fruit expansion stage and berry stage, respectively.

3. Fruit period management

The yield per mu should be controlled at 1500-2000 kg as far as possible, leaving 2 ears on strong branches, 1 ear on medium-strong branches, and no ear on weaker branches, cutting off new shoots far away from main vines or crosses to make the shelf surface more organized. When the fruit grows to the size of soybeans, remove the poor fertilization, unable to develop small grains, deformed grains and pest grains, and leave large grains as much as possible. Bagging can make the fruit surface clean, bright and beautiful, at the same time, it can control fruit diseases and insect pests, spread reflective film under the shelf after removing the bag, and remove the shaded leaves near the ear, so as to promote uniform coloring and full coloring of the ear.

4. Pest control

In planting, strong disease resistance should be selected, and before only sprouting, the whole plant was sprayed with stone-sulfur mixture to eradicate overwintering pathogens and overwintering pests, which played a significant role in reducing the disease throughout the year. Spraying Bordeaux solution at flowering stage can prevent black pox and downy mildew; spraying methyl topiramate once a week when the fruit grows to the size of soybeans can prevent ear rot; during fruit growth, spraying Bordeaux solution alternately with carbendazim and chlorothalonil can prevent anthracnose and downy mildew.
