The five most important fertilizer management in the vineyard

In the past few years, there have been many diseases in the vineyards. Most of them are due to unreasonable fertilization and watering. The following is a detailed description of the five most important fertilizers and waters in the vineyards. It must be mastered. The fertilization and irrigation of vineyards must be carried out according to the requirements of the fertilizers and fertilizers of the grapes and the local soil fertility. It should not be blind.

Grape five irrigation methods

1. In the budding stage: Watering before the grapes are unearthed and sprouted. In spring drought-scarce areas, it is also necessary to fill once with water to meet the needs of sprouting grapes.

2. In the late flowering period before flowering: Persimmon water is irrigated before and 10 days after flowering. Before flowering, the flower fertilizer is applied in combination, and the fertilizer is dissolved in water and can be quickly absorbed by the roots, which has a significant effect on promoting the rapid growth of inflorescences, ovary, pollen, and improving the pollination effect and fruit setting rate.

3, berry period: When the berry grows to the soybean grain size, the new shoot also grows vigorously, at this moment the temperature rises continuously, the leaf water evaporates the volume to be bigger and bigger, urgently needs the nutrient and the water. Therefore, in late June, it is necessary to combine the application of fruit fertilizer to stimulate fruit and water. When there is little rain at this stage, water should be poured every 7-8 days to meet the needs of new shoots and berry growth.

4. Berry enlargement period: In the berry period before the ear matures, combine the fertilizing irrigation once before the berry ripening water, this can supplement the lack of water in the late growth period of grapes, increase the yield and quality of the grapes, and promote the ripening of the ear.

5, post-harvest period: After the harvest of fruit to cold before irrigation to 2 to 3 times, in order to improve soil moisture, promote root growth and development, moist branchlets, to prevent draining. In arid regions, the frozen winter water must be allowed to air for 2 to 3 days after it is poured. After the surface soil is dry, it will be buried and protected from the cold to prevent the humidity of the soil from being excessive, causing the bud eyes to rot.

Five stages of grape fertilization

1. Precipitating Fertilizer: Generally applied before the grape is sprouted. This time, nitrogen fertilizer (a large amount of water-soluble fertilizer is appropriate) is used as the main purpose to promote neat germination, the leaves are thick, and the inflorescence is large and strong. If the tree vigor is too prosperous and the spring is not very dry, this fertilizer can be saved, so as not to cause new shooters.

2. Inflatable fertilizer: After the grapes are set, the fruits are like mung beans, and they are applied as late as soybeans. The fertilizer is dominated by nitrogen and both phosphorus and potassium fertilizers are applied. High nitrogen compound fertilizer can be applied, ordinary three-element compound fertilizer can also be applied, and nitrogen fertilizer such as urea can be added as appropriate. This time, the amount of fertilizer should be large, which can account for about 50% of the amount of chemical fertilizer applied throughout the year.

3, ripening fertilizer: in two. 20 to 30 days before maturity, high-potassium water-soluble fertilizer is applied, and when the grape berries start to soften, and no coloring is applied, the fertilizer is applied once more. This fertilization is very important. After many farmers have applied large fertilizers, they no longer apply ripening fertilizers, or cause fruit coloring (commonly known as water jar disease) or due to lack of fertilizers. Grapes are not resistant to disease and are prone to disease, and high yields are not harvested. Or poor coloring, low sugar content, no good price, etc. Can be directly applied into the functional fertilizer, a large number of elements in water-soluble fertilizer (recommended high-phosphorus high potassium type, while containing trace elements boron and zinc).

4, "monthly child fat": refers to the harvest after the grape, pay close attention to the application of a fertilizer, usually a large number of elements of water-soluble fertilizer (high nitrogen type) 15 kg, the role of this fertilizer is not only used to restore tree vigor, and promote Differentiation of flower buds lays the foundation for high yields in the following year.

5. Akiaki fertilizer (overwintering fertilizer): The traditional method is to apply it when the grape is dormant. In recent years, it was advocated for August and September. After the grape was harvested, it was also applied during the growth of green shoots. This is the second peak in the growth of grape roots, which can promote a large number of fibrous roots in order to grow stronger and more conducive to wintering. The fertilizer is mainly organic fertilizer (if you are applying farmyard fertilizer, please pay attention to decomposing), apply calcium fertilizer at the same time, or add a small amount of three elements.

The amount of fertilizer and the amount of fertilizer each year can be determined according to the conditions of the soil, the age of the tree, the level of yield and the quality of the fertilizer. After each fertilization, the water should be poured once. The larger the amount of water, the better, and the larger the amount of water, resulting in loss of fertilizer and water. After the big fertilizer is applied, two waters must be poured and the interval between the two is usually 5 to 7 days. In addition, before winter, the grapes should be poured once per year. After the soil is loose, it is cultivated once and it is extremely beneficial to antifreeze.
