Embodiment Construction

[0008] The technical solutions and technical effects of the present invention will be further described below in conjunction with specific embodiments.

[0009] 1. Study on the etiology of pineapple heart rot

[0010] The inventor has carried out many years of investigation and sampling research to pineapple heart rot, and found that:

[0011] (1) After the soil and plants have accumulated water for a long time, the young tissues of roots and stems, and the base of leaves can only carry out anaerobic respiration, and gradually suffocate and rot to death. This further illustrates that pineapple heart rot is a non-infectious disease.

[0012] (2) Under the same low temperature and rainy environment, there are diseased plants but more healthy plants at the same time, which shows that the internal cause of the disease lies in the balance of nutrient elements inside the plant, that is, the abundance and deficiency of nutrient elements. After analysis, the nutritional composition ...

Abstract

Disclosed is a method for preventing and treating pineapple heart rot. Nutritional agents are used, heart filling treatment is performed on pineapple plants for 50-60ml / plant before coming of the low temperature, and the nutritional agent formula is 0.1% to 0.4% of a borax solution and 1% to 3% of a calcium chloride solution. According to the method, the formula is simple, the pertinence is high, pineapple heart rot can be prevented and treated effectively, and time and labor are saved; the pineapple plant cold resistance and disease resistance can be improved apparently, and the yield is improved.

Description

technical field [0001] The invention relates to the technical field of pineapple disease prevention and control, in particular to a method for preventing and treating pineapple heart rot. Background technique [0002] Pineapple heart rot disease, also known as rotten heart disease, was first discovered in India in 1945. It has occurred in various pineapple producing areas in the world. It also often occurs in Guangdong, Guangxi, Fujian and other provinces in my country. It usually occurs in winter and spring when the temperature is low and rainy. It often occurs in heavy rain, heavy soil, easy to accumulate water or low-lying land, continuous cropping land or after planting in autumn. After continuous low temperature and rainy weather in Nanning City, the incidence of pineapple heart rot is as high as 50%. [0003] Scholars on the etiology of pineapple heart rot have different opinions. At present, there are 6 Phytophthora species reported at home and abroad, and only Phytoph...
