Pollution-free production of tomato and eggplant fruit bagging technology

I. Significance and purpose of fruit bagging cultivation In recent years, the production of pollution-free vegetables has been highly valued by the society. People use low toxicity, short residual period and biological pesticides to achieve the purpose of pollution-free vegetable production. For the one-time harvested vegetables, such as Chinese cabbage, spinach, rapeseed, etc., according to the residual period of the pesticide in the pre-harvest period, stopping the use of the medicine at a certain time before the harvest can serve the purpose of producing pollution-free vegetables. However, for fruits and vegetables that have been harvested many times, such as tomatoes, eggplants, cucumbers, etc., it is difficult to stop the use of medicines before harvesting. For example, vegetables and pests are serious, and the number of spraying is high, especially during the harvesting period. Pests and diseases, the fruits after harvesting are likely to be listed in the residual period of pesticides, which will adversely affect the physical and mental health of the citizens. This is a problem that needs to be solved in the production process of pollution-free vegetables. The method of fruit bagging cultivation has been adopted to improve the occurrence of pollution-free vegetables and add a new way. Linyi Fertilizer Network Copyright

Second, the method of fruit bagging cultivation After the growth and flowering of the fruit, the tomato is bagged after the fruit is removed by thinning and thinning. The bag is 220 mm long, 165 mm wide and 0.08 mm thick. The transparent polyethylene is transparent. Film bag (can also be more fruit bagging, multi-fruit bag is short of the disease is easy to infect pests and diseases), the film bag is placed on the fruit, and then the film bag mouth is tied with the wire in the fruit handle, but can not Too tight, to prevent the lateral growth of the fruit stalk, while maintaining a certain air permeability or sheathing the mouth with a rubber band. The rubber band has a certain degree of tightness that can be expanded with the growth of the fruit stalk. To reach the market standard, the fruit is listed together with the bag; the method of bagging the eggplant is to select the disease-free fruit after the eggplant is placed on the fruit, and the bag is sleeved on the fruit. The size of the bag is 220 mm long, 200 mm wide and 0.008 mm thick. Degradable transparent film bag, after the film bag is set, the wire is tied with the wire in the handle, and the mouth should have a certain degree of looseness, so as not to affect the lateral growth of the fruit stalk, and at the same time have a certain ventilation or rubber band Mouth, wait until the fruit grows up Linyi Fertilizer Network Copyright

Third, the fruit bagging effect and advantages After fruit bagging cultivation, fruit bagging can promote the growth of the fruit, and make the fruit color fresh, tomato bagging time is August 15 - September 12, 2001, For a total of 28 days, after the single fruit bagging, the average lateral growth of the fruit before the bagging was 14.0 mm, the vertical average growth was 12.8 mm, and the horizontal and vertical values ​​were 26.8 mm. The control (fruit without bagging) showed an average lateral growth of 13.2 mm. The average growth was 10.8 mm; the horizontal and vertical values ​​were 24.6 mm. The treatment was more than 2.8 mm in horizontal and vertical values ​​compared with the control. The reddening time treatment was 5-7 days earlier than the control (horizontal refers to the widest lateral distance of the fruit, The vertical direction refers to the longest vertical distance of the fruit body, and the horizontal and vertical values ​​are added horizontally and vertically. The eggplant bagging time is 20 days from September 15 to October 5, 2001. After the bagging, the average horizontal growth was 27.9 mm, the vertical average increased by 44.4 mm, the horizontal and vertical values ​​were 72.3 mm, the control (not bagging) increased horizontally by 29.1 mm, the vertical average increased by 42.0 mm, and the horizontal and vertical values ​​were 71.1. Millimeter, the treatment is 1.2 mm more than the horizontal and vertical values ​​of the control; It affects its growth and can promote it. Fruit bagging cultivation has the following advantages: Linyi Fertilizer Network Co., Ltd.

1 It can prevent the concentrated pesticide from being sprayed directly onto the fruit and is not listed in the residual period after being adsorbed by the epidermis of the fruit. 2 can promote tomato fruit early red, avoid chemical pollution caused by chemical agents to promote red fruits. 3 After fruit picking, the film bag is formed into a small package and directly listed, which improves economic income. 4 The film bag does not affect the growth and development of the fruit, and promotes the growth. 5 In the case of the application of pollution-free pesticide production, the fruit bagging cultivation of the fruits and vegetables harvested repeatedly will make the production of pollution-free vegetables safer, more reliable and of higher quality. 6 film bags can be used in ultra-thin polyethylene film bags, or ultra-thin degradable film bags, the latter is better, no pollution to the environment, and has a promising future.
