Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.

1. Strawberry: Strawberry plants are short, shade-tolerant and have a short growing period. Before the formation of the grape leaf curtain, the process of flowering and fruition can be completed. It is complementary to the grape in the use of land, light and temperature. It is an ideal room. crop.
There are many varieties of strawberries, and large fruit varieties with short dormancy, early maturity, high yield and disease resistance suitable for facility cultivation should be selected, such as Baojiaoshengsheng, Red Gloves, Gorella, Hongyi, Mingjing, Minglei, Chunxiang, Jinmei No. 22 and so on.
Strawberries in the colonization greenhouse should be cultivated into strong seedlings in the open field and moved to the rows of grapes in the greenhouse from September to October. After growing a few new leaves, they will pass through the winter. In early February of the next year, they will grow as the temperature within the facility increases. In early April, the strawberry fruit began to ripen and go on the market. In early May, the strawberry fruit that had already been fruited was moved to the open ground and continued to grow seedlings. From September to October, it was moved to the greenhouse again.
In the facility, strawberry is susceptible to powdery mildew and gray mold. It should be sprayed 70% thiophanate-methyl wettable powder 1500-2000 times or more than 50% once every half-month before the budding of strawberry until two weeks before harvesting. Bacillin 1000 times to prevent and control. The heavy flowering of strawberries will increase the disease, reduce the yield and quality, and should be planted after two to three years.
2. Vegetables: Set up interplanting vegetables in the rows of grapes and arrange them. You can plant them all year round and harvest them several times. For example, in North China, the cultivars of vegetable intercropping are: in early November, the leeks roots are moved into greenhouses, and after the last leeks are harvested in late March, they are moved to open fields, and then radishes are grown. After harvesting, the mushroom was planted with garlic at the beginning of August. After harvesting, the garlic was transplanted into the leeks, or the celery seedlings were transplanted into the greenhouse in late December. After harvesting in April of the following year, the species of Pleurotus ostreatus was harvested and moved again in mid-September. Jincai root supply for the Spring Festival market.
In addition, electric heating lines can be laid between the rows of grapes for vegetable seedlings. Between January and February, cabbages, tomatoes, peppers and cucumbers can be cultivated. Also, watermelons, melons, grapes, and other nutrients and nutritional bags can be quickly nursed.
3. Herbs: Grapes are suitable for planting gastrodia, and Tianma requires a shady, moist environment. The lush foliage of grapes just acts as a shade. In addition, it is also possible to cultivate potted ginseng under the condition of shade under the grape frame.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
Intercropping technique of grape
In order to increase the utilization of land and space in the shed facilities and increase income, limited intercropping can be conducted without affecting the growth and results of the grapes. Especially in the first year or two after the grape is planted, the grapes are small and the coverage is low. It is possible to make full use of some dwarf plantlets with short growing periods. From the third year onwards, the vines have grown and there is insufficient light between the rows, and the intercropping between the vines and the growth of the intercropping crops is still unfavorable. At this time, only fruit and vegetables with short growth period can be planted in the period before the flowering stage of the grape leaf (flowering period), or potted plants can be hung in the indoor space and three-dimensional cultivation can be carried out. However, it is not allowed to grow tall stalked crops and vegetative vegetables, or vegetables with a long growing period, in order to avoid glory with the grapes, compete for water, and compete for nutrients. At present, there are more kinds of crops in the interior of the grape shed:
