Description
Technical field
The present invention relates to chemical weed control method field, be specifically related to a kind of Ipomoea cairica and use different chemical herbicides its method of preventing and kill off according to different growing environments and growth time.
Background technology
Ipomoea cairica (
Ipomoea cairica) originate in the North America, be the perennial liane of Convolvulaceae, be one of 37 kinds of the most harmful instruction plants of China (Qiao Q. Huang et al., 2009).Because its fast growth is called as " one mile of per minute " (mile a minute) in Australia, its asexual multiplication ability is also extremely strong simultaneously, as long as stipes contacts to earth and can breed the plant that makes new advances.Therefore, in a single day Ipomoea cairica is invaded the forest land and is just tended to sprawl rapidly and spread, cover on other plant, and by changing the sense effect, thereby the growth that further suppresses local species develops into single kind of advantage group.Also therefore, Ipomoea cairica has had a strong impact on recovering naturally of agricultural and forestry production and wasteland vegetation, becomes the second largest evil grass that the South China is only second to Mikania micrantha.The control research of preventing and kill off at Ipomoea cairica at present mainly contains: Wang Yongfan and Hu Yujia (2000) report with 2 first, 4 chlorine and 2, the certain multiple dilution of 4-D butyl ester is prevented and kill off Ipomoea cairica, and Pang Junxiao etc. (2009) invention mixes by a certain percentage with Nongdeshi and Acetochlor removes Ipomoea cairica.In fact, because Ipomoea cairica adaptability is strong, be difficult to thoroughly prevent and kill off in the time of mostly, by a large amount of tests, the effect quality that we find to remove Ipomoea cairica with weed killer herbicide is except outside the Pass having with the weed killer herbicide kind of using, and also habitat type and the growth time thereof with Ipomoea cairica has very big relation.Concrete management technology method at different habitats type and growth time Ipomoea cairica is not arranged at present as yet, use existing technology removing Ipomoea cairica still to have removing and thoroughly or at the Ipomoea cairica of climbing on tall and big tree be not difficult to many weak points such as operation.Therefore, we propose new more detailed method and solve these problems, cover the shortage.
Summary of the invention
The objective of the invention is to thoroughly or at the Ipomoea cairica of climbing on tall and big tree not be difficult to deficiencies such as operation according to the removing that exists in the existing Ipomoea cairica the method for control, provide a kind of the distribution to use different chemical herbicides to its method of preventing and kill off with the Ipomoea cairica of growth time according to different growing environments, this method can thoroughly be removed Ipomoea cairica, help the ecological balance, be suitable for extensive use.
The object of the invention is achieved by the following technical programs:
The inventive method is to utilize 2, and 4-D butyl ester, three kinds of chemical herbicides of dicamba and fluroxypyr are prevented and kill off the Ipomoea cairica in different growth times and the different growing environment, and method is as follows:
(1) to be in the short ecotope and growth time less than the Ipomoea cairica in 1 year, can thoroughly kill by simple spray medicine.With 2,4-D butyl ester, dicamba and three kinds of weed killer herbicides of fluroxypyr are easier to prevent and kill off the Ipomoea cairica in 1 year, any one is an amount of to get these three kinds of weed killer herbicides, calculate dilute with water 5000 times (2 by active ingredient, the 4-D butyl ester) or 1000 times (dicamba and fluroxypyr), put into then in the sprayer, it is drenched that the cauline leaf of Ipomoea cairica is sprayed to the blade face, the spray medicine after 15 ~ 20 days, thoroughly kill Ipomoea cairica;
(2) be two to be difficult to thoroughly prevent and kill off to for many years Ipomoea cairica vegetative period, and in fact exteriorly complete dead Ipomoea cairica behind the spray medicine may also have many old rattans and root not dead.Therefore, improve the dosage of weed killer herbicide, with 2 of 500 ~ 2000 times of dilutions of active ingredient, it is wet entirely that the dicamba soup of 4-D butyl ester soup or 500 ~ 1000 times of dilutions is sprayed to the blade face to the Ipomoea cairica cauline leaf, can reach better killing effect.The Ipomoea cairica climbing highly is lower than the habitat of 3m, as easier enforcements such as wasteland, irrigation canals and ditches, sylvan life, shrubbery and little trees.2, behind 4-D butyl ester and the dicamba spray medicine, drug effect can continue three months long, 4 ~ 5 months not dead old stems of five pawls gold can be sprouted again and grow new cauline leafs in a large number, dispenser once more at this moment behind the spray medicine;
(3) the fluroxypyr medicine liquid spray with 1000～500 times of dilutions of active ingredient also can kill the leaf of Ipomoea cairica and longer then stem, but be difficult to kill older stem, 1 ~ 2 month a large amount of not dead old stem begins to sprout behind the medicine, and Ipomoea cairica returns to original state rapidly.Therefore prevent and kill off growth Ipomoea cairica for many years without fluroxypyr.Because the environment soil fertility condition is different with growth time, the growing way of the Ipomoea cairica of different location is widely different, at the Ipomoea cairica on the wattled wall, if growth time is short, it is loose to distribute, less to the level of coverage of hedge, can also see through the thing that hedge is seen another side, with 2 of 1000 times of dilutions of active ingredient, 4-D butyl ester soup or 500 times of dilution dicamba soups are sprayed towards the one side of hedge, can thoroughly kill the Ipomoea cairica on the wattled wall; If growth time is long, densely distributed, it is very high to cover the hedge degree, can not see through hedge and see thing, and then all will spray in the two sides of hedge over there.Ipomoea cairica climbing degree height should be cut off from base portion earlier, bottom spray 2, and 500 ~ 1000 times of dilutions of 4-D butyl ester if the leaf of the latter half Ipomoea cairica is less, should wait two weeks at least, treat to spray medicine again after Ipomoea cairica grows a large amount of new cauline leafs;
(4) for the Ipomoea cairica that climbs to the high point, cut off its base portion earlier, spray 2 of 500 ~ 1000 times of dilutions of active ingredient in its underpart, 4-D butyl ester soup.
For obstinate Ipomoea cairica, except using said method, can also kill Ipomoea cairica by the stem medicine-injecting method, promptly vertically scratch the long breach that gos deep into the stem marrow of 5 ~ 10cm together with pocket knife at the stem base portion, fill a prescription 2 about 1 ~ 2mL with being with the north material of sharp mouth bottle to inject in the breach then, 4-D butyl ester, or dicamba, fluroxypyr can thoroughly be killed Ipomoea cairica after one month.Stem obviously thicker again Ipomoea cairica is easier to implement, and therefore, the Ipomoea cairica that the growth time of climbing on Da Shu, roof or wall reaches the several years relatively is fit to remove with this method.
Prevent and kill off the effect of Ipomoea cairica in order to reach the best, preferably be chosen in calm fine day and spray medicine.2,4-D butyl ester, dicamba and three kinds of weed killer herbicides of fluroxypyr are easy to buy on market, and common prescription is that content is 2 of 72wt%, 4-D butyl ester missible oil, the dicamba aqua of 48wt% and 200g/L fluroxypyr missible oil can directly be bought according to this method and use.Also can because pure dicamba is not soluble in water, use pure dicamba, should use the appropriate amount of organic dmso solution earlier, and then be diluted with water to corresponding multiple with pure former medicine.Same a kind of prescription weed killer herbicide that different manufacturers is produced uses the killing effect to Ipomoea cairica to have certain difference by same dosage.Implementation process, large-scale sprayer is higher than the spray drug effect rate of miniaturised nebuliser, by the every mu of soup that needs spray 40 ~ 60kg of weed killer herbicide operation instruction of filling a prescription usually, use the above sprayer of capacity 10L to achieve the goal easily, the use capacity may need more soup less than the sprayer of 5L.
Compared with prior art, the present invention has following beneficial effect:
Prevent and kill off convenient, flexible, the easy operation of Ipomoea cairica with this method, weed killer herbicide selects kind many, according to the growth time and the habitat characteristics dispenser of Ipomoea cairica, can tackle the different growth conditionss of Ipomoea cairica comprehensively, and preventive effect is good; Three kinds of weed killer herbicides are selective herbicide, and are little to the woody plant injury when removing the forest land Ipomoea cairica; It is not only thorough but also minimum to the influence of environment to kill Ipomoea cairica by the method for stem breach perfusion.
