Problems solved by technology

At present, in China, chemical control is one of the main measures to suppress A. chinensis, but it is prone to secondary pollution of water bodies; in terms of physical control, cutting and salvage are mainly used, but cutting is costly, time-consuming and labor-intensive, and the effect is not good. Good, the salvage effect is good, but the cost is high, time-consuming and labor-intensive

Embodiment 1

[0010] 1. Select the same batch of Alpinia sinensis plants and plant them in plastic buckets, respectively label the plastic buckets with numbers 1-10 and the blank control, place them in a room with a room temperature of 25°C, and give them appropriate light;

[0011] 2. Pour clean water into the barrel planted with Hollandia chinensis;

[0012] 3. Make sure that the water is above 30cm from the highest growth point of A. chinensis. After one month, the growth of the plant is obviously inhibited.

Embodiment 2

[0014] 1. Select a 120-square-meter concave swamp, in which there are lotus hollows growing, the water quality in the swamp is clear, and a cofferdam is set at the outlet of the concave swamp;

[0015] 2. Store water in the concave swamp, and flood the hollow lotus;

[0016] 3. Keep the Alpinia sinensis in a completely submerged state, and ensure that the flooding is above 30cm from the highest growth point of the Alpinia sinensis;

[0017] After 1 month, the growth of A. japonicus was significantly inhibited in the fully submerged state.

Abstract

The invention discloses a method for inhibiting the growth of A. chinensis, which comprises the following steps: setting cofferdams around water outlets around swamps and lakes where A. coffering grows; setting gate valves on the cofferdams; storing water with a water quality of Clean water, flood the Alyssa sinensis; keep the Auscullosinia in a completely submerged state, and ensure that the water is above 30cm from the highest growth point of the A. Select the swamps and lakes where the water quality is mainly clear water, and adopt the above method to effectively suppress the growth cycle of A. chinensis, and the suppression effect is the most obvious at the depth of water inundation at 30 cm, and the plant height decreases by an average of 4 cm in the third week. Width decreased by 0.3cm and 0.2cm on average in the second week, reaching the maximum inhibition period; achieving the effect of inhibiting its growth.

Description

technical field [0001] The invention relates to a method for preventing and controlling plants, in particular to a method for inhibiting the growth of Asteria spinosa. Background technique [0002] Hollow lotus (Latin name: Alternanthera Philoxeroides (Mart.) Griseb) is a perennial herbaceous plant of the family Amaranthaceae. It widely grows in areas with an altitude of 50 meters to 2700 meters, mostly in swamps and ditches. It has strong reproductive ability, endangers biodiversity and destroys the ecological environment, and at the same time blocks water traffic, reduces crop production, and affects farmland drainage and irrigation. Introduced to China in 1930, it is an extremely harmful invasive species and is listed as the first batch of invasive alien species in China. At present, in China, chemical control is one of the main measures to suppress A. chinensis, but it is prone to secondary pollution of water bodies; in terms of physical control, cutting and salvage ar...
