Abstract
The invention discloses an ipomoea cairica chemical preventing and removing method which imposes herbicide on the ipomoea cairica to prevent and remove the ipomoea cairica. The herbicide is a mixed reagent of Londax and acetochlor with a ratio of 6:1-3:1. The method of the invention can effectively remove the ipomoea cairica and can prevent the regrowing of the ipomoea cairica.
Description
Technical field
The present invention relates to noxious plant control field, specifically, relate to a kind of chemical control method of Ipomoea cairica.
Background technology
Ipomoea cairica (Ipomoea cairica) is Convolvulaceae (Convolvulaceae) herbaceous perennial vine, originate in North America, now be distributed widely in the torrid zone and subtropical zone, Ipomoea cairica is usually with seminal propagation, grain weight is big, germination rate height, breeding are grown rapidly easily, but only bloom in the area, Guangdong, seldom solid, mainly utilize stem to carry out vegetative propagation, all can nourish and grow the whole year.The ability of climbing of Ipomoea cairica twining stem is strong, along trunk and on, occupy the periphery of other plant rapidly, the tree crown of close lid trees causes the plant that is capped to can not get enough sunlight and death.It is to green plants, and especially ornamental plant is very harmful.Ipomoea cairica spreads in China's south China Zhu Sheng large tracts of land in recent years, and only its area coverage has reached more than 40 ten thousand square metres in the Baiyun Mountain Scenic Spot of Guangzhou, has become one of the most serious Exotic Harmful Plants of Guangzhou and even whole South China harm at present.For many years its artificial removing is not only expended a large amount of manpower and financial resources, and preventive effect is impermanent, the phenomenon of waking up from death often occurs.
Summary of the invention
The object of the invention is to overcome the deficiency of the method for control of existing Ipomoea cairica, provides a kind of effective Ipomoea cairica chemical control method at the spreading range and the growing environment of Ipomoea cairica.
To achieve these goals, the inventive method adopts following technical scheme:
Adopt mass ratio be 6: 1～3: 1 Nongdeshi and Acetochlor mix reagent as weed killer herbicide, according to the coverage and the growing environment of Ipomoea cairica, insecticide-applying way is divided into following three kinds:
1. non-directional spray-on process: for the Ipomoea cairica of large tracts of land harm, or the Ipomoea cairica in moistening, the moist growing environment, can become the droplet dispersion suspension in air the weed killer herbicide medicine liquid spray with sprayer, drop to again on the Ipomoea cairica, the soup trickling be arranged up to the blade of Ipomoea cairica;
2. directed spraying method: for not serious Ipomoea cairica of the extent of injury or arbor and the shrub that is climbed by Ipomoea cairica, can spray medicine, the soup trickling be arranged up to the blade of Ipomoea cairica with stem, the leaf that sprayer is directly aimed at Ipomoea cairica;
3. root dispenser method: for the Ipomoea cairica of the crown canopy of climbing high megaphanerophyte or shrub, stem and the root that can seek Ipomoea cairica on the ground carry out dispenser, also can carry out dispenser to its root soil, and the soup trickling is arranged on stem.
In the chemical control process to the large tracts of land Ipomoea cairica, because the problem of spraying or spraying the back demutation takes place to leak often, the general requirement sprayed medicine 2～3 times.For generally spraying medicine, after 2～3 months, the place of leaking spray is for the first time filled spray for the second time for the first time; As also having the situation of Ipomoea cairica demutation, then should spray medicine for the third time, it is standard that spray date regrows flouring with Ipomoea cairica at interval, general 6～12 months at interval.
The time of using this method that Ipomoea cairica is carried out chemical control is annual 5～November, because be summer and autumn, the Ipomoea cairica growth is vigorous this moment, and is all better to conducting in the absorption of weed killer herbicide and the body.Wherein, during 6～September Ipomoea cairica growth the most vigorous, medication this moment preventive effect the best.
Compared with prior art, the present invention has following beneficial effect:
The present invention can effectively eliminate Ipomoea cairica fast, also can prevent its demutation, has saved manpower and materials, is beneficial to environmental protection.
Embodiment
Embodiment 1
More than 3 years, large tracts of land cover to be irritated thick grass for growth, and cover degree adopts the non-directional spray-on process evenly to spray soup to the cauline leaf of Ipomoea cairica greater than 60% Ipomoea cairica, and formulation rate is a 30g/ mu, and spraying number of times is 3 times.
Embodiment 2
Below 2 years, large tracts of land cover to be irritated thick grass for growth, and cover degree is less than 60% Ipomoea cairica, adopts the directed spraying method that the cauline leaf of Ipomoea cairica is directly carried out even dispenser, and formulation rate is a 15g/ mu, sprays number of times 2 times.
Embodiment 3
For the Ipomoea cairica of the general filling thick grass of growth more than 3 years, employing directed spraying method is directly carried out even dispenser to the cauline leaf of Ipomoea cairica, and formulation rate is a 30g/ mu, sprays number of times 2 times.
Embodiment 4
For the Ipomoea cairica for the general filling thick grass of growth below 2 years, employing directed spraying method is directly carried out even dispenser to the cauline leaf of Ipomoea cairica, and formulation rate is a 15g/ mu, sprays number of times 2 times.
Embodiment 5
For growing in the Ipomoea cairica of height greater than the high forest of 4m, adopt root dispenser method that the root and the stem of Ipomoea cairica are sprayed back and forth, formulation rate is a 15g/ mu, sprays number of times 2 times.
Embodiment 6
For growing in the Ipomoea cairica of height less than the high forest of 4m, adopt the directed spraying method that the root and the stem of Ipomoea cairica are sprayed back and forth, formulation rate is a 15g/ mu, sprays number of times 2 times.
Embodiment 7
For the Ipomoea cairica that grows in moistening or the wet environment, adopt the non-directional spray-on process evenly to spray soup to the cauline leaf of Ipomoea cairica, formulation rate is a 45g/ mu, sprays number of times 2～3 times.
The result of embodiment 1-7 is as shown in table 1.
The treatment effect of Ipomoea cairica among the table 1 embodiment 1-7
The above results shows that the inventive method can effectively be eliminated Ipomoea cairica, and suppresses its growth and demutation.
