Problems solved by technology

Winter tomatoes are often in a low temperature environment, so the ripening period of tomato fruits in this season is longer, and the fruit coloring is poor
In recent years, there has been a strong demand at home and abroad for "string-type" tomato fruits harvested by whole ears, and the price is more than twice that of single-harvested tomatoes. It is difficult for general tomato varieties to meet this technical standard
In addition, due to the long growth period of tomato and many pests and diseases, producers have to use pesticides in the production process to maintain the yield of tomatoes, resulting in direct contact of tomato fruits with a large amount of pesticides, which aggravates the pesticide pollution of products

Embodiment Construction

[0010] The invention includes the material, structure, size and production method of the special bag for tomato fruit. During the specific implementation, the following methods of operation should be noted:

[0011] The fruit bag is made of colorless transparent plastic film as the outer bag and black paper as the inner bag to make a double-layer fruit bag. The fruit bag is 300-400 mm long and 200-250 mm wide. The plastic film of the outer bag has mechanically punched micro-holes; the paper of the inner bag can be kraft paper or sulfuric acid paper, but there is a certain gap between the inner and outer bags; except for the upper bag Outside the mouth, a three-side sealing is implemented, and the upper bag mouth is fixed with a thin soft plastic-coated iron wire to facilitate the bagging and fixing on the fruit handle and the mouth. In order to enhance the water permeability and air permeability of the fruit bag, the bottom corners of the fruit bag each have small holes with a d...

Abstract

The invention contains two aspects, namely, the development of a specific fruit bag for cluster trimming and bagging of tomato fruits and the application technology thereof. The warming fruit bag takes a colorless and transparent plastic film as an outer bag and black paper as an inner bag; and the plastic film of the outer bag has millipores formed by mechanical stamping. After the fruit setting of tomatoes, the whole fruit of a tomato is totally bagged in the fruit bag, thus playing the role of regulating temperature and moisture, promoting the growth and early maturity of tomato fruits, and enhancing pigment synthesis. Through bagging treatment on overwinter tomatoes, ambient temperature for fruit development is increased by more than 3 DEG C, the growth speed is increased by 22.7% compared with contrasts, the mature period is 5-8d early than being expected, the weight of single tomato is increased by more than 15.3%, the lycopene of fruits is increased by 49.72%, and the pesticide residues are also significantly reduced compared with the contrasts.

Description

1. Technical Field [0001] The technical invention relates to a special fruit bag for tomato fruits in a winter greenhouse, including materials, structures, dimensions and production methods, and belongs to the technical field of agricultural production supplies manufacturing. 2. Background technology [0002] With the development of society and the improvement of people's living standards, consumers have higher and higher requirements for vegetable products. People not only require vegetable products to be rich in nutrients and low in pollution residues, but also to have beautiful appearance. Therefore, in recent years, the production of high-quality and safe vegetables has taken the world by storm. However, environmental factors, technical factors, and biological factors in the process of vegetable production restrict the quality of vegetable products. [0003] A large number of studies and production practices have shown that the ripe coloring of tomato fruits is closely related...
