Field management technology of grape

Grape cultivation has a long history and is one of the oldest fruit trees in the world. And now grape is also a popular fruit on the market, and it can also be processed into snacks and even a very popular wine. Grape planting has certain requirements for the environment, but also need to have professional planting skills, so today and Xiaobian to learn the field management techniques of grape planting.

1. Management at seedling stage

Generally, the field management of grape is carried out after grape seedlings are planted, and the main purpose after planting is to improve the survival rate of grapes and promote the growth rate of grape seedlings. When the grape seedlings are planted, if there is no rain, then we need to water reasonably according to the drought degree of the weather to promote the growth of new grape roots. The second is according to the growth of grape seedlings, reasonable topdressing fertilizer to promote the growth of grape seedlings, especially when the seedling leaves appear yellowing phenomenon, we should carry out topdressing and supplement nutrition. Topdressing at seedling stage is mainly carried out in accordance with the principle of frequent application of thin fertilizer, at the same time mainly nitrogen fertilizer, combined with the use of organic fertilizer. Finally, it is necessary to weed in time, generally with shallow ploughing, to avoid damaging the plant roots and to prune reasonably at the same time.

2. Growth period management

The natural growth period of grape is to promote the growth of grape seedlings, make it quickly enter the flowering and fruiting period, and shorten its growth cycle. During this period, we mainly take fertilization as the main management technology, and at the same time, fertilization is still dominated by nitrogen fertilizer, which needs to be combined with the use of phosphorus and potassium fertilizer. If the soil is deficient in calcium or other trace elements, it also needs reasonable supplementary application of micro-fertilizer. Another very important thing at this stage is to build a support to pull the grape seedlings to the support to climb and grow, which can improve the permeability of the field, at the same time reasonably pick the heart and promote the growth of lateral branches. Finally, according to the water demand, reasonable watering, and combined with ploughing, this can promote the absorption of nutrients.

3. Result period management

The management of the result period generally needs to be carried out in several steps, which can not be achieved overnight. First of all, in the spring bud stage, we need to apply fertilizer once, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, to promote the growth and sprouting of grapevine branches and leaves. The second is to wait until the grape seedlings blossom, a topdressing, mainly phosphorus and potassium fertilizer, the purpose is to protect flowers and fruits. Of course, at this time, we also need to carry out reasonable flower thinning and fruit thinning, which is also to improve the yield and quality of grapes and reduce physiological fruit drop. Finally, when the grapes grow to the size of soybeans, it is necessary to apply strong fruit fertilizer, mainly foliar fertilizer, usually using borax to achieve the purpose of strong fruit.

4. Post-harvest management

After the grape harvest, we have to carry out field cleaning and disinfection, so as to reduce the damage of diseases and insect pests, but also reduce some pathogens from the root causes. At this stage, we can also prune the grapevines properly, such as old branches, withered branches, disease and insect branches and so on. Finally, fertilizing is carried out after clearing the garden, mainly by composting, which can prepare the grapes for overwintering and high yield in the coming year.

The field management of grape is also a crucial step in grape planting technology, and it is also the key to high yield of grape. Today, the editor gives you a brief introduction to the field management technology of grapes from its various growth stages, hoping to help you.
