The latest method to increase the yield of grape

China's grape market is very spectacular, every grape production season, the streets can see the traces of grapes, but also sell very well, but in recent years there are a lot of external factors leading to the reduction of grape yield, quality reduction, then today pro-agricultural network to teach you a few tricks, so that everyone's vineyard grape variety, exquisite, the following with the small series to take a serious look at it.

1. Select good seeds

To increase grape yield, grape varieties are the basis for high grape yield, so we need to choose the most suitable varieties for local growth with excellent resistance, so as to fundamentally increase grape yield. Now grape varieties are very many, at least there are hundreds of species, so how to distinguish the good and bad grape varieties? There is a primary school question here, that is, you need to observe the roots of grape seedlings, see whether the roots are developed, and it looks very vital, followed by observing the branches and leaves of seedlings, to see whether the color is uniform, and to observe whether the moisture of its stems is relatively sufficient, and finally to see whether the climate environment of the planting area is suitable for the variety, so the selection of seeds is also very simple.

2. Fertilizer and water science

Grapes are very particular about fertilization and watering. There are three key fertilization periods for grapes except base fertilizer. We must fertilize correctly at the right time. The first fertilization is in the germination period. In order to make the seedlings grow new branches, and not let the new branches grow excessively, we generally use appropriate farm manure mixed with a little phosphorus fertilizer and compound fertilizer. The total amount is controlled at about 1,000 jin. If the soil fertility is not enough, we can also add five jin nitrogen fertilizer and five jin urea. The second fertilization is after the grapes have fallen, then the fruit is successful, then we need to fertilize to promote the growth of the fruit, this time mainly nitrogen fertilizer, then mixed with a small amount of phosphorus and potassium fertilizer, the last time is when the fruit grows almost and then changes color, if we want the grape color ratio to be uniform and look very bright, then we need to apply phosphorus and potassium fertilizer. Every time fertilization should be watered at the same time, there are two purposes of watering, the first is to promote growth, the second is to avoid the grape seedlings burned out caused by food costs, for a dilution effect.

3. Branch arrangement

Branches and leaves management is a very important step in grape yield increase. In order to prevent grape seedlings from growing too vigorously, we need to prune some branches and leaves. Of course, it is not so simple. We need to prune according to the growth of main seedlings. Generally, we keep the branches and leaves that are stronger than Orney, cut off the branches and leaves that grow poorly or have diseases, and finally apply a layer of chemicals to them after pruning to prevent infection by germs and diseases.

4. Erection and construction of shed

We all know that grape planting definitely needs to build scaffolding, but this is not a simple matter. In general, we'd better set up scaffolding in a herringbone shape, and then connect each scaffolding with iron wires. The direction of the scaffolding must be regular. Finally, the grape seedlings should be supported on the scaffolding and let them crawl along the iron wires. If there is irregular growth, subsequent adjustments are needed. Each adjustment must be handled gently. Also, don't move the grape seedlings easily after the results.

5. Thinning flowers and fruits

Grape growth rules are not the same, so sometimes in the vineyard, you will find that each grape seedling is densely filled with flowers, full of small grapes, this is not the time you are happy, at the same time you do not feel reluctant, you need to be more dense where the grapes to protect the principle of large and good to remove the appropriate amount of other fruits, so as to maintain normal growth.
