The method of increasing yield of grape

China's grape market is very spectacular, every grape production season, grape traces can be seen in the streets, but also sold very well, but in recent years, there are many external factors leading to the reduction of grape output and quality, then today's pro-agricultural network to teach you a few tricks, so that everyone's vineyard grapes dazzling, exquisitely carved, the following with the editor to take a serious look.

1. Select improved varieties

If we want to increase the yield of grapes, then the variety of grapes is the basis of high yield of grapes, so we need to choose the most resistant varieties that are most suitable for local growth, so as to fundamentally increase the yield of grapes. Now there are many varieties of grapes, at least a hundred or so, so how to distinguish the advantages and disadvantages of grape varieties? There is a primary school question here, that is, you need to observe the roots of grape seedlings to see whether the root system is developed, and it looks very vital. The second is to observe the branches and leaves of the seedlings, to see if the color is uniform, and to observe whether the moisture in its stems is relatively sufficient. Finally, it is to see whether the climatic environment of the planting area is suitable for the varieties, so seed selection is also very simple.

2. Fertilizer and water science

Grapes are very particular about fertilization and watering. There are three key time periods for grapes to get rid of base fertilizer. We must apply fertilizer correctly at the right time. The first fertilization is in the germination period, in order to make the seedlings grow new branches. And can not let the new branches grow, so we usually use the right amount of farm fertilizer mixed with a little phosphate fertilizer and compound fertilizer, the total amount is controlled at about 1000 jin. If the soil fertility is not enough, you can also add five jin of nitrogen fertilizer and five jin of urea, and the second fertilization is after the grapes have fallen, then we need fertilization to promote the growth of the fruit, this time mainly nitrogen fertilizer. Then mix a small amount of phosphate and potassium fertilizer, the last time is when the fruit grows almost and then changes color, if we want the color of the grapes to be even, it looks very bright. Then phosphate and potash fertilizer need to be applied. Each fertilization should be watered at the same time, watering has two purposes, the first is to promote growth, the second is to avoid food costs caused by the burning of grape seedlings, a dilution effect.

3. Branch and leaf finishing

Branch and leaf management is a very important step in increasing grape production. In order to prevent grape seedlings from growing too vigorously, we need to prune some of the branches and leaves. Of course, it is not as simple as pruning. We need to prune according to the growth of the main seedlings of grape seedlings. In general, it is necessary to retain the branches and leaves that are stronger than the price, and cut off the branches and leaves that grow poorly or have diseases. Finally, after cutting it off, you need to apply a layer of medicine to it to prevent it from being infected by germs and diseases.

4. Build a shed

We all know that grape planting must need to build scaffolding, but this is not a simple thing. In general, we had better build the scaffolding with herringbone, and then connect each scaffolding with iron wire. The direction of the scaffolding must be found regularly. Finally, the grape seedlings are supported on the scaffolding and let them crawl along the wire. If there is irregular growth, it also needs to be adjusted later. Each adjustment must be handled gently, and do not move the grape seedlings easily after the result.

5. Thinning flowers and fruits

The growth rules of grapes are different, so sometimes in the vineyard, you will find that each grape seedling is densely covered with flowers and small grapes. This is not a time for you to be happy, and at the same time, you should not feel reluctant to give up. You need to remove the grapes in the denser areas and remove the other fruits properly, so that you can maintain normal growth.
