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 growing period of tomato and many pests and diseases, producers have to use a large amount of 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

[0007] The invention includes the determination of the bagging period for whole ear of tomato fruit, the selection of quality material and the application of the bagging method and the like. During the specific implementation, the following operation methods should be paid attention to:

[0008] The whole ear bagging of tomato fruit includes selecting the appropriate bagging period, bagging method and bagging period. The best period for tomato bagging is: 3 to 4 inflorescences of large-fruited varieties, 5 to 6 inflorescences of medium-fruited varieties, and about 90% of small-fruited varieties. If the bagging is too early, The fruit is easy to fall off. Spray the fungicide evenly in the field before bagging. When bagging, remove the deformed fruit and the flowers that have not set the fruit. Put the ear into the bag from the bag mouth to the main fruit handle. Then, gently fix the soft iron wire on the bag mouth. On the stalk of the main fruit. After the tomato fruit is ri...

Abstract

The invention discloses a whole-spike bagging safe production method for tomato fruits, a special fruit bag which has warming and heat preservation functions consists of an outer bag made of a colorless transparent plastic film and an inner bag made of black paper, the bagging is carried out in the initial stage of tomato inflorescence fruit setting, and after the fruits are ripe, the whole spike is harvested and marketed. The method is used for greenhouse tomato production in winter and can promote fruit expanding obviously, improve pigment synthesis capability, ensure the fruit coloring to be uniform and the fruits to expand, shorten the fruit ripening period and obviously reduce pesticide residue pollution to the fruits, and the method can be directly popularized and applied to the greenhouse tomato production in winter.

Description

1. Technical field [0001] The technical invention relates to a bagging cultivation method for tomato fruit whole ear, and belongs to the technical field of high-quality and safe production of agricultural products. 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 nutrition and low in pollution residues, but also to have beautiful appearance. Therefore, in recent years, high-quality and safe vegetable production has become popular all over the world. However, environmental factors, technical factors, and biological factors in the process of vegetable production all restrict the quality of vegetable products. [0003] A large number of studies and production practices have shown that the ripening and coloring of tomato fruits are closely related to the ambient temperature. Within a cer...
