Four New Technologies Sunlight Greenhouse Grapes "Back to Old Age"

The grape "rejuvenation" technology introduced here is characterized by the fact that the grapes that have been planted for many years are like new plants. As a result, the male vines are both annual and annual, and the grapes are of good quality, are listed on the market, are pollution-free and have high profits. This technique is described as follows:

Four conditions for returning new technology applications

First, the solar greenhouse

The usual high-temperature greenhouses are designed to heat up early and heat well to ensure that the grapes have a long growth period, which provides time guarantee for returning to the new and annual production.

Second, followed by dense planting

It is cultivated in large and small rows with a row spacing of 1 meter, a row spacing of 0.5 meters, a plant spacing of 0.35-0.4 meters, and planting of about 2300 plants per 667 square meters. It can also be planted with equal spacing. The general spacing is 1 meter and the spacing is 0.3-0.4 meters. Planted 1668-2223 plants per 667 square meters.

Third, management measures

Artificial sleep

After the grapes fall out of the fallen leaves, the night temperature is around 7°C (above 0°C and below 10°C), and the sheds can be promptly covered and covered with straw curtains. Cover grass curtains during the day, shading, and open the air outlet at night to reduce the temperature of the greenhouse; close all air outlets during the day to keep it cool. Most grape varieties can meet low temperature requirements after 30-40 days of low temperature pre-cooling.

Lime-N breaks dormancy: grape can be germinated 20-25 days earlier than untreated after treated with lime nitrogen. When used, every kilogram of lime nitrogen, mixed with warm water of 40-50°C and 5 kg into plastic bucket or wood In the pot, stirring constantly, about 1-2 hours, make it even into a paste, to prevent caking, before use, add a small amount of adhesive in the solution, with a sponge, cotton ball and other peony bud spread, spread Grape vines can then be placed on the ground and moistened with a plastic film.

2. Temperature regulation

After meeting the low temperature demand, the temperature should be raised slowly, and the temperature cannot be raised too quickly. The temperature should be controlled at 15-17°C in the first 3-5 days. Afterwards, the straw curtains were uncovered at around 8 a.m. every morning, so that the greenhouses were warmed up and covered with straw curtains at 4 pm. Before germination, the minimum temperature at night is controlled at 5-7°C, and the maximum temperature during the day can reach 30°C. Before germination to flowering, the low temperature at night is 7-15°C, the high temperature during the day is 24-28°C, and the optimum temperature is 20-25°C. The minimum temperature during the flowering night is 10-15°C, and the maximum temperature during the day cannot exceed 30°C and the optimum temperature is 22-26°C to facilitate pollination and fertilization.

3. Humidity control

Before and after germination to inflorescence extension period, the humidity can be appropriately larger, the relative air humidity of the greenhouse can reach 80%-90%; the inflorescence is controlled at about 70% after extending; the flowering period is moderately dry, which is conducive to anther cracking and pollen emission. The humidity can be maintained from 50% to 60%, but over-drying will affect the fruit set. In other periods, the relative humidity of air is controlled at about 60%.

Four applications for returning new technologies

First, the variety returned. The usual method for replacing our varieties is to cut off the heavy plant or to replace it with a graft. The first method requires a long period, a waste of time, and there are problems such as the spread of soil-borne diseases and pests; the second method also has an annual non-result phenomenon, which affects economic efficiency. What we are adopting today is to return new crops without affecting the second year's output. Second, there is no problem of soil-borne pests and diseases. The key point is to use the characteristics of dense planting and long growing period in the greenhouse under the condition of basic conditions. After the temperature of the shed is warmed up, the newly planted grafted grape varieties will grow on the base of the grape, and the new variety will grow after grafting and healing. Far longer than the grape growing period of longevity. Therefore, it is said that there is enough growth time to grow the prep. However, in the earlier period before June, due to other results, vines dominated the growth and carried yields, during which period the growth of new varieties of viable grapes was controlled. When the original grape variety was harvested, the old varieties would have been restocked in June, leaving only ready-to-live vines for rapid growth. Thus, the return of new varieties has been realized.

Second, the preparation of new mother. The renewal and rejuvenation of grape vines is a common technical measure. However, it is rare that the vines are ran a year after birth. The application of this technical measure has allowed the grape to return to its new year with a fast and orderly return. The yield is high and the quality is good. . The specific method of operation: First, after the temperature rise of the grapes in the solar greenhouse, the vines that are intended to remain at the base of the grapes are taken as the cranberries. Before June, the growth of the vines should be appropriately controlled. After entering the month of June, the results will be re-stretched until the leaves are ready for vines, and the growth of the vines will be accelerated. This will result in the growth of the vines after the fall to the second year. The vines, so that year after year, new year after year, the grapes that have been planted for many years look as if they were just cultivated, as if they were leveled once in June, and the new vines result in the realization of the grains, spikes and spikes of the grapes. Neat and tidy, high yield, good quality, and high efficiency.

Third, the environment returned to new. Grape growing environment is the key to the formation of yield and quality. Usually, we often say that the removal of fallen leaves is used to prevent and control pests and diseases. However, it often does not result in thorough cleaning. There will always be residual leaves and leaves in the orchard. The vine or grafted variety grows rapidly, making it grow into a robust, parental vine. At the same time, the resulting shoots are removed and the pests deposited on the old vines are removed. In this way, the environment in the solar greenhouse was cleared up, so that the environment could be returned year after year, laying the foundation for the production of green, pollution-free grapes.

Fourth, the root system returns to new. The root-cutting technique is a commonly used technical measure in the growth process of fruit trees, but it is not commonly used in actual production. Here we talk about root returning which is the specific application of the root-cutting technology, and it is also a necessary technical measure, and of course, it can also be combined with grapes. Post-harvest underground fertilization in June was carried out to create a relative balance between underground and ground growth, stimulate the growth of underground new roots, ensure the normal growth on the ground, and obtain a healthy grape.

Organic Spirulina Powder is extracted from 100% natural Spirulina. Spirulina is neither an animal nor a plant, it is actually a natural freshwater alga. Its protein content is incredibly high. It also contains iron, vitamin B6, and several other micronutrients. Ensuring that micronutrient intake is maintained is very important to ensure optimal physical condition.
