Embodiment 1

[0044] Take about 30 centimeters of sucking buds, put them upside down and dry the roots for 7 days on a sunny day, remove the leaflets and dry leaves at the base of the sprouts, and expose the root points, and prepare a 200-fold solution with 20% pine and 80% Forsaide wettable powder, The root of the sucking bud is placed in the solution and soaked for 3 minutes, then inverted and air-dried, and then planted in a flower pot with a diameter and a height of 70 cm, and the bottom of the flower pot has air holes. The soil is made of coconut peat and gardening soil at a ratio of 1:1. Before potting, apply enough base fertilizer in the soil, put 1 catties of compound fertilizer and 4 catties of organic fertilizer in each pot. When the plants start to grow new leaves until they grow to 5 new leaves, apply 75 grams of high-nitrogen compound fertilizer per pot, apply compound fertilizer (75 grams of urea + 40 grams of potassium sulfate) twice after the middle seedling stage, and apply...

Embodiment 2

[0053] The main difference between this example and Example 1 is that the formula of medicinal solution A is 0.5% potassium dihydrogen phosphate, 0.5% calcium dodecylbenzenesulfonate and 0.5% magnesium sulfate;

[0054] The formula of liquid medicine B is 10% potassium dihydrogen phosphate, 5% calcium dodecylbenzenesulfonate and 10% magnesium sulfate;

[0055] The formula of liquid medicine C is 0.5% potassium dihydrogen phosphate, 0.5% calcium dodecylbenzenesulfonate and 0.5% magnesium sulfate.

[0056] Spray medicinal solution A 30 days before harvesting, spray medicinal solution B 20 days before harvesting fruit, spray medicinal solution C 10 days before harvesting fruit, the incidence rate of water core disease of pineapple plants is 0.5%.

Embodiment 3

[0058] The main difference between this example and Example 1 is that the formula of medicinal solution A is 10% potassium dihydrogen phosphate, 5% calcium dodecylbenzenesulfonate and 10% magnesium sulfate;

[0059] The formula of liquid medicine B is 0.5% potassium dihydrogen phosphate, 0.5% calcium dodecylbenzenesulfonate and 0.5% magnesium sulfate;

[0060] The formula of liquid medicine C is 10% potassium dihydrogen phosphate, 5% calcium dodecylbenzenesulfonate and 10% magnesium sulfate.

[0061] Spray medicinal solution A 30 days before harvesting, spray medicinal solution B 20 days before harvesting fruit, spray medicinal solution C 10 days before harvesting fruit, the incidence rate of water core disease of pineapple plants is 0.3%.

Abstract

The invention provides a liquid medicine and method for preventing and controlling pineapple water core disease. The liquid medicine is sprayed in the pineapple fruit growth stage, and the liquid medicine formula comprises the following components in percentage by mass: 0.5%-10% of potassium salt, 0.5%-5% of dodecylbenzene sulfonate and 0.5%-10% of magnesium salt. The liquid medicine is easy to obtain, the spraying method is simple and easy to implement, the pineapple water core disease incidence rate can be greatly reduced, and losses caused by pineapple water core diseases of farmers are reduced.

Description

technical field [0001] The invention relates to the field of pineapple planting, in particular to a medicinal solution for preventing and controlling pineapple water core disease and a method thereof. Background technique [0002] Pineapple is the third largest tropical fruit in my country and plays an important role in the economic development of tropical and subtropical regions in China. Pineapple fruit is a physiological disease. After cutting, the pulp section is water-soaked. It is more common in caine and its hybrids. The commercial performance of this kind of fruit is poor. Once found, the pineapple fruit in the whole field will have difficulty in selling. In the wholesale market, once water pumpkins are found, the entire batch of pineapples will face the dilemma of not being sold and can only be thrown away on the spot. Water fruits often bring great losses to farmers. It is of great significance for the healthy development of my country's pineapple industry to ...
