Embodiment 1

[0020] The water hyacinth management method of the present embodiment comprises the following steps:

[0021] (1) Before the water hyacinth blooms in July and when the temperature is high, the treatment begins. Use wooden strips to connect the water hyacinths in the growth area of ​​water hyacinths by connecting them end to end to form a pile with a length and width of 4m and 1m respectively. Rectangular water hyacinth returns to the heap area, and the plant density of the water hyacinth in the heap area is 2 times of the normal growth state;

[0022] (2) Evenly spray 2 kg of saturated brine prepared with potassium chloride to the water hyacinth stacking area;

[0023] (3) Cover the water hyacinth stacking area sprayed with saturated salt water with a green plastic film. The plastic film isolates the sunlight and creates a continuous high temperature and high humidity environment. After 23 days of covering, the water hyacinth leaves and stems turn yellow and rot, and the water...

Embodiment 2

[0027] The water hyacinth management method of the present embodiment comprises the following steps:

[0028] (1) Before the water hyacinth blooms in August and when the temperature is high, the treatment begins. Use bamboo strips to connect the water hyacinths in the growing area end to end to form a pile with a length and width of 4m and 1m respectively. Rectangular water hyacinth returns to the heap area, and the plant density of the water hyacinth in the heap area is 2.5 times of the normal growth state;

[0029] (2) Evenly spray 2.5 kg of saturated brine prepared with potassium chloride to the water hyacinth stacking area;

[0030] (3) Cover the water hyacinth stacking area sprayed with saturated salt water with a brown plastic film. The plastic film isolates the sunlight and creates a continuous high temperature and high humidity environment. After 40 days of covering, the water hyacinth leaves and stems turn yellow and rot, and the water hyacinth is fatal. The rate rea...

Embodiment 3

[0034] (1) Before the water hyacinth blooms in August and when the temperature is high, the treatment starts. Use PVC pipes to connect the water hyacinths in the growing area end to end to form a pile with a length and width of 4m and 1m respectively. Rectangular water hyacinth returns to the heap area, and the plant density of the water hyacinth in the heap area is 3 times of the normal growth state;

[0035] (2) Evenly spray 3 kg of saturated brine prepared with magnesium chloride to the water hyacinth pile area;

[0036] (3) Cover the water hyacinth stacking area sprayed with saturated salt water with a black plastic film. The plastic film isolates the sunlight and creates a continuous high temperature and high humidity environment. After 50 days of covering, the water hyacinth leaves and stems turn yellow and rot, and the water hyacinth is fatal. The rate reached 98%;

[0037] (4) Lift off the covering plastic film and expose the rotten water hyacinth to a high temperatur...

Abstract

The invention discloses a water hyacinth treatment method, and relates to the technical field of environmental treatment. The method comprises the following steps of treating water hyacinths in months with higher temperature, gathering and enclosing the water hyacinths to a pile to form a water hyacinth heaping area, spraying saturated salt water to the water hyacinth heaping area, and covering the water hyacinth heaping area with a plastic film until leaves and stems of the water hyacinths become yellow and rot; and removing the the plastic film, exposing the rotten water hyacinths in the high-temperature environment for one week, and after the part, above the water surface, of the water hyacinths is dehydrated and withered, fishing out the withered water hyacinths. The method solves the problems that an existing water hyacinth treatment method cannot effectively control growth and propagation of the water hyacinths, and the ecological environment is affected.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a water hyacinth treatment method. Background technique [0002] Water hyacinth is one of the vicious alien species that has invaded South China, Central China, East China, and Southwest China. It reproduces rapidly and competes with local aquatic plants for light, water, nutrition, and growth space, affecting the diversity of aquatic organisms and blocking River courses and irrigation canals affect agricultural irrigation and water transportation, and have an indirect impact on the economy. [0003] In order to reduce the impact of water hyacinth on the aquatic environment, the principle of "prevention first and comprehensive control" is adopted to effectively control the reproduction of water hyacinth at a lower cost and control the harm of water hyacinth below an acceptable level. At present, physical, chemical and biological control techniques are mainly used...
