Cherry village difficult disease prevention and control
Demonstration Engineering Technology Program
First, demonstration significance and purpose
The cherry tree, which is full of beautiful fruits and sweet, charming cherry trees, is called "the first spring branch" and its economic value is second to none. At present, with the continuous introduction and development of cherry tree species, its planting area is also expanding. However, the accompanying "three major diseases" of cherry trees - root cancer, necrotic ring spot disease, and fruit cracking - have also increasingly jeopardized the production of cherries. The use of traditional chemical pesticides has not been effective or effective. . In 2003, Dalian Ganjingzi District Agricultural Technology Promotion Center adopted the product “Magic Formula†No. 5, No. 6, and No. 7 of shell sugar amine plant disease resistance developed by Dalian Baolvbao Marine Life Sciences Research and Development Center Co., Ltd., in Dalian Ganjingzi. The fruit tree boutique park of Qiange Village in Xinzhaizi Township and the orchard garden of Zong'an Village in Hongqi Street were tested successfully to prevent cherry tree root cancer. In the spring of 2004, the cherry tree boutique park, which continued to use Rubik's Cube, significantly reduced the incidence of necrotic ring spot disease and fruit cracking in the cherry trees, and greatly improved the yield and quality. Based on this experiment, we plan to implement the “Demonstration Project for Stereo Biological Prevention and Control of Cherry Difficult Diseases†to ensure the healthy growth of cherry trees and increase the income of farmers.
Second, test materials and methods
1, test materials. The Rubik's Cube No. 5, No. 6, and No. 7 produced by Dalian Baoluobao Marine Life Sciences Research and Development Center Co., Ltd., and other auxiliary biological pesticides introduced by the company were used.
2, varieties: medium and late maturing varieties
3. Base fertilizer: Fermented farmyard fertilizer is fully fermented, 1000 times “magic square†1 is added, and 300 times “fresh green treasure organic leaf fertilizer†produced by Dalian Xianlvbao Organic Leaf Fertilizer Co., Ltd. is added.

Control methods
Fruit root cancer
Early spring budding period, after fruit harvest
1. The trunk showed that the secreted resin was gray-brown and sunken after drying. The epidermis showed a neoplasia at the late stage, and the new leaf on one side was wilty and even died. 2. The rhizomes are wrinkled and shaped like mustard.
1. The method of applying the scraping method to trunk diseases is to first scrape off the affected part with a knife, exposing the formation layer without injury, and if the formation layer has been infected with the disease, then how much part of the blackened part is scraped off. In the upper part of the lesion, it is 1-2 cm longer to the healthy part, and the healthy part below the lesion is 2-3 cm longer. After that, apply the following formula: apply 100 times dilution of “Rubishi†No. 7 alginate to the wound, and then use 500 times “cube†No. 6 chitooligosaccharide citrate + disinfection 300-500 times dilution Apply it to the wound and apply it to the wound with a 50-fold dilution of "Cube" No. 7 carboxymethyl chitooligosaccharide citrate preservative, which can be effectively controlled on the trunk in advance.
2, on the basic treatment of mustard tumors: should first spread the topsoil of the tree disk, exposing the roots, the tumor-like disease with a knife removed, with the "magic" No. 7 seaweed extract 100 times diluted on the wound, and then use 500 times the "magic cube" 6th oligosaccharide citrate + 300-500 dilution of the disinfection fled smear on the wound, and finally with "Magic" No. 7 carboxymethyl chitosan citrate protectant 50-fold dilution Smear on the wound, control for half an hour, then smear once again according to the above concentration of 50%, after the water seepage and then seal the soil recovery, while sealing the soil side with a drug residue irrigation. 3, in the fruit before harvest or fertilization in early spring, add the total amount of base fertilizer 1/3-1/4 active biological bacteria fertilizer, the farm fertilizer must be fully fermented, also will "magic" 5 1000 times spray on In the base fertilizer after fermentation, the soil environment in the rhizosphere is improved.
Necrotic ring spot
From leafing to fruiting
Ring-shaped spots on the leaves, spreading and falling off
500 times the "Magic" 2 + 800 times seaweed extract + 600 times oxygen spray, every 10-15 days, a total of 3 times.
Split fruit disease
Green ripening period before picking
Fruiting vertical cracks and fruit drop
After the fruit is set, 800 times of "Rubifang" No. 2 + 500 times seaweed extract is sprayed, once every 5-7 days, for a total of 3 times (can be combined with the treatment of necrotic ring spot treatment, and combined). On the day before picking, or when picking the package, spray, dip, and smear with 500 times Rubik's Cube No.3.
5. In the control group, trunks and root systems were not treated. When spraying on the foliage of the experimental group, the control group was covered with a plastic cloth, so that it could not receive the medicine, and was sprayed with fresh water daily, and the spraying was performed simultaneously with the test group.
Third, the survey project
1, trunk, root lesion healing, new incidence
2. Growth and development of shoots, heavy leaf weight, and diseased leaf rate
3. Fruit 100-grain weight, 100-fruit cracking rate, fruit ripening time after picking (days), and room temperature preservation period.
4, fruit hardness, sugar content, acidity, product shape, price (yuan / kg)
