Description
Technical Field
The invention relates to the technical field of green ecological prevention and control, in particular to a method for reducing damage of ampullaria gigas to rice by returning tobacco waste to fields.
Background
The ampullaria gigas (Pomacea canaliculata) is also called as a large bottle snail and an apple snail, is introduced into domestic cultivation as a foreign species, but the ampullaria gigas has extremely strong reproductive capacity and lacks control of natural enemies, so that the ampullaria gigas rapidly spreads in China, and the result is a disaster, serious damage to crop production occurs, the ampullaria gigas becomes a serious agricultural pest in most of the provinces in the south, and the occurrence area of farmland snails in Guangdong province reaches more than 800 ten mu. In 2003, the national environmental protection agency and the national academy of sciences of China also put ampullaria gigas on a "blacklist" of 16 foreign species that first invaded China.
In the face of agricultural and ecological hazards caused by ampullaria gigas in the whole country, chemical molluscicides are the first choice of most farmers and are widely applied to the prevention and control of Yu Fushou snails, and as a result, quite verified environmental pollution, reduced biological diversity and grain safety problems are caused. There is therefore a need to propose an alternative to chemical molluscicides to solve the above problems.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention aims to provide a method for reducing the damage of the ampullaria gigas to rice by returning tobacco waste to the field, and the tobacco leaves are put into the rice field, so that the double effects of attracting the ampullaria gigas and directly poisoning the ampullaria gigas can be achieved, and the aim of killing the ampullaria gigas by utilizing the tobacco waste to achieve the green control of the ampullaria gigas is achieved.
The technical aim of the invention is realized by the following technical scheme:
a method for reducing damage of ampullaria gigas to rice by returning tobacco waste to fields comprises the following specific steps:
s1, collecting top leaves of footing leaves generated by tobacco planting, sun-drying, grinding the footing leaves and the top leaves into powder, putting the powder into a paddy field before transplanting rice seedlings, and transplanting the rice seedlings after a period of time;
s2, collecting footing leaves generated by tobacco planting, putting the footing leaves into a paddy field, and collecting the ampullaria gigas enriched on the footing leaves at intervals.
Ineffective footing leaves are generated in the tobacco planting process, and the footing leaves are generally processed directly in the field, but the method is wasteful and the possibility of spreading diseases and insects exists. The invention applies the footing leaves generated by tobacco planting to the rice field to prevent the ampullaria gigas, thereby realizing the reutilization of resources and realizing green control.
In one embodiment, in step S1, the bottom leaf and top leaflet are ground into a powder, which is then sieved through a 10-40 mesh sieve to obtain a dry powder of tobacco waste leaves having a particle size of 0.425-2 mm. Crushing tobacco into powder is beneficial for dissolving the active ingredients (namely nicotine) in the tobacco into water, and the particle size of the powder cannot be too large, otherwise, the active ingredients of the powder are influenced to be completely released in the water.
In one embodiment, in step S1, the bottom leaves and top leaves are ground into powder, and the powder is sealed and stored for later use to prevent the powder from absorbing water and regaining moisture.
In one embodiment, in step S1, the powder is applied to the rice field at a rate of 30-50 g/square meter 1-4 days before transplanting the rice seedlings.
In one embodiment, in step S1, the paddy field water remains stationary and the paddy field water depth remains between 1cm and 5cm. It is easy to understand that the shallower the water, the higher the nicotine concentration after powder administration, and the better the killing effect.
In one embodiment, in step S2, the footing She Si is formed into 5-10cm wide leaves for use after collecting the footing leaves resulting from the tobacco planting. The tobacco leaves are shredded, so that the effective components in the tobacco leaves are released in time, and the death speed of the ampullaria gigas after the tobacco leaves are eaten is increased.
In one embodiment, in step S2, the footing leaves are thrown every 2-5m within 1m from the ridge along the direction of the ridge of the paddy field.
In one embodiment, in step S2, 50-100g of footing leaves are thrown every 2-5m within a range of 1m from the ridge along the direction of the ridge of the paddy field.
In one embodiment, in step S2, after the putting of the footing leaves is completed, the ampullaria gigas enriched on the footing leaves is collected after an interval of 2-6 hours for killing or utilizing.
In summary, the invention has the following beneficial effects:
the invention puts fresh tobacco leaves into the rice field, and can obtain the double effects of attracting the ampullaria gigas and directly poisoning the ampullaria gigas. Researches show that the ampullaria gigas is loved to eat tobacco leaves, and the tobacco leaves have the effect of attracting the ampullaria gigas. According to the invention, after the dried tobacco leaves are crushed and returned to the field, when the concentration of the tobacco powder reaches 1g/L, the death rate in the adult snails reaches more than 80% in 96 hours, and the aim of killing the ampullaria gigas by utilizing tobacco waste to control the ampullaria gigas is fulfilled.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
It should be noted that the terms "upper", "lower", and the like referred to herein are all used for convenience of description only and should not be construed as limiting the technical solution.
The invention provides a method for reducing damage of ampullaria gigas to rice by returning tobacco waste to fields, which comprises the following specific steps of killing the ampullaria gigas before planting and killing the ampullaria gigas during planting:
s1, collecting and sun-drying invalid footing leaves and top small leaves generated in the tobacco planting process, grinding, sieving with a 10-40 mesh sieve to obtain dry powder (particle size of 0.425-2 mm) of waste tobacco leaves, and sealing and preserving for later use; the tobacco leaf powder of 30-50 g/square meter is put into a rice field (water body does not flow, and the water level of the rice field is kept at 1-5cm water depth) according to the ratio of 1-4d before transplanting rice seedlings to kill the ampullaria gigas.
The invention kills the ampullaria gigas by utilizing nicotine in waste leaves of tobacco (namely nicotine), waste leaves produced in the tobacco planting process, such as footing leaves or top leaves, are dried, rolled into powder and then put into water, the nicotine in the tobacco is released, an environment unsuitable for survival of the ampullaria gigas is formed in a paddy field, young and adult snails of the ampullaria gigas are killed, and dead ampullaria gigas can be remained in a paddy field and can also be used as nutrients. It is easy to understand that even in the planting process, the water body containing the tobacco leaf powder in the rice field can play a role in killing the ampullaria gigas, and the number of the ampullaria gigas is effectively limited.
S2, collecting invalid footing leaves generated in the tobacco planting process, and partially tearing the invalid footing leaves into leaves with the width of 5-10 cm; putting 50-100g of tobacco leaves at intervals of 2-5m within a range of 1m from the ridge along the rice field ridge; and after putting the tobacco leaves for 2-6 hours, fishing the ampullaria gigas enriched on the tobacco leaves by using a net bag, and killing or utilizing the ampullaria gigas.
For places without water holes or other places unsuitable for throwing tobacco leaf powder in the rice field, the tobacco leaves are used for attracting the ampullaria gigas to gnaw, so that the purpose of enriching and killing the ampullaria gigas is achieved.
It should be noted that, step S1 and step S2 may be performed simultaneously, for example, killing the ampullaria gigas before planting, powder may be put into the non-flowing water body to kill the ampullaria gigas in the water body, tobacco leaves may be put into the rest of the water body to attract the ampullaria gigas to gnaw, and after enrichment, the ampullaria gigas may be killed in the same way, powder may be kept put into the water body and tobacco leaves may be put into the paddy field.
As shown in figure 3, adult ampullaria gigas prefers to ingest tobacco, so the invention uses tobacco as a raw material for killing ampullaria gigas. Different lowercase letters represent that the cumulative feeding count of the ampullaria gigas on different solanaceae crops (the sum of the numbers of the snails feeding a certain crop is observed at 0.25, 0.5, 1, 2, 4 and 6 hours of the test treatment respectively) achieves a significant difference. The cumulative number of the ampullaria gigas fed with the eggplant leaves and the tobacco leaves does not reach the significant difference, the cumulative number of the ampullaria gigas fed with the tomato leaves and the capsicum leaves does not reach the significant difference, and the rest two by two reach the significant difference.
As shown in fig. 1, the higher the unit dosage of the powder is, the better the killing effect on young snails, middle snails and adult snails is for the step of killing the ampullaria gigas by throwing the powder into the water body.
As shown in fig. 2, for the step of feeding tobacco leaves to attract the ampullaria gigas for gnawing, feeding fresh tobacco leaves has a good effect on killing both adult snails and young snails, and particularly for young snails, the effect of killing is good after feeding fresh footing leaves for 6h, so in the invention, preferably, the ampullaria gigas enriched on tobacco leaves is fished by a net bag after feeding fresh footing leaves for 6 h.
The invention avoids returning the invalid footing She Zhijie generated in the tobacco planting process to the field, possibly spreading and wasting diseases and insects, and puts the tobacco into a paddy field or dries and pulverizes the tobacco for later use, effectively utilizes the invalid footing leaves and the top lobules, avoids using a large amount of tobacco waste generated in the cigarette production process, greatly reduces the material cost, cuts or pulverizes the invalid footing leaves and the top lobules after drying in the sun, avoids using a drying box, a pulverizer and other devices required for manufacturing tobacco stem powder, is easy for farmers to operate, and effectively reduces the manpower transportation cost because the dry powder consumption of the tobacco waste leaves is 300-500kg per hectare.
