Description
Technical Field
The invention relates to an indoor raising method of Chinese pennisetum.
Background
Spiders belong to the Araneida (Arachnida) order of the Arthropoda, prey on various agricultural and forestry pests, are a very important natural enemy group in the agricultural ecosystem, and maintain the stability of the system to a certain extent. The spiders are broad-spectrum predators, have large predation amount, can prey on different insect states such as eggs, larvae and imagoes of insects, and are specially used for preying on live insects (dead insects are not generally taken for feeding). The spiders are various in species, strong in environmental adaptability and wide in distribution, and the quantity of pests can be effectively controlled, so that the crop yield is increased. In recent years, researches on spider toxins, silk glands and medicinal value are becoming hot.
Chinese wolfsbane (Lycosa sinesis) belongs to the genus of wolfsbane of the family of Nelumbonaceae, and is a cave-dwelling spider. The Chinese pennisetum individuals are large (female spider 1.9-3.0cm, male spider 1.5-2.1cm), strong in physique, rapid in activity and predatory to inland disabled, are called as 'swordsmen' in the southwest Lu, are natural enemies of various harmful insects such as tortoise shells, noctuids and the like, and have important development and utilization values.
To remove agricultural pests, chemical control is currently the most widely used. The chemical control has quick effect, simple use and low price, but the pesticide is not used properly, so that the pests can generate drug resistance and kill other beneficial natural enemies, and even the serious people can cause poisoning of people and livestock. Chemical contamination can also occur when pesticides penetrate into the soil. Compared with chemical control, the biological control effect is slower, but the use of chemical pesticides is reduced, various natural enemies in nature are protected, the virtuous cycle of agriculture and forestry ecological balance is promoted, and the long-term effect is worthy of affirmation.
The occurrence of the Chinese pennisetum alopecuroides is seasonal and cannot be collected all the year round in the field, and the occurrence rate and the survival rate of the Chinese pennisetum alopecuroides in the field are not high due to climate and food, so that the search for a method for indoor feeding of the Chinese pennisetum alopecuroides is extremely important.
Small hunting spiders such as crab spider and Xiaoyao spider usually stay between plant branches and leaves to wait for prey to pass; the small pennisetum and the pano-web spider such as the leopard spider usually walk on the ground. The Chinese pennisetum is a cave spider with a large body size and usually nests in the soil. It does not stay between the branches and leaves of the plant, and most of the time, it lives in the nest. Therefore, the pennisetum sinense is raised indoors, and soil needs to be provided for nesting for normal life.

Detailed Description
The following examples are given to facilitate a better understanding of the invention, but do not limit the invention. The experimental procedures in the following examples are conventional unless otherwise specified. The test materials used in the following examples were purchased from conventional biochemicals, unless otherwise specified. The quantitative tests in the following examples, all set up three replicates and the results averaged.
The indoor raising method of the Chinese pennisetum comprises the following steps:
1. preparation of cultivation soil
The coconut soil without impurities is sterilized in an autoclave to be used as the culture soil.
The selected soil is coconut soil, and the moisturizing performance is high. The soil needs to be sterilized at high temperature three times, one hour each time, to remove germs and microorganisms in the soil. If no sterilization condition exists, the soil can be exposed to the sun for 6-8 hours.
Selecting soil: coconut soil is preferred, and when the coconut soil cannot meet the requirement, garden soil exposed to the sun can be used for replacing the coconut soil.
The reason for selecting a soil having high moisture retention performance is as follows: the coconut soil has good moisture retention performance, and can reduce the water adding times, thereby reducing the disturbance to the Chinese pennisetum.
2. Preparation for raising Chinese pennisetum environment
Referring to fig. 1, the cobweb box is made of white colloid plastic boxes, the size of the cobweb box is 1 × high, 2 × long, 3 wide (9-11cm) × (9-11cm) × (9-11cm), the cobweb box is not too big or too small, too small is not favorable for Chinese wolf spider activity, too big is not favorable for temperature and humidity control, vent holes 5 are arranged on four side surfaces, the vent holes 5 are positioned on the upper 1/3 part of the side surface of the cobweb box, and the total area of each side surface vent hole is 0.01-0.04cm2(avoid young spider to flee away) between, make enough air vent and can make chinese wolf spider obtain sufficient oxygen, but every side air vent total area can not be too big, otherwise be unfavorable for accuse temperature accuse wet, the air vent 5 of every side can be a plurality ofly, size unanimity and evenly distributed between a plurality of air vents is preferred, the air vent coats and is stamped the screen window in order to prevent chinese wolf spider to climb away. A circular operation opening 8 and a cover (not shown) matched with the circular operation opening are arranged at the top of the spider cage, and food and soil can be added from the operation opening. The cover of the operation opening is made by cutting a screen window into a proper size, and after all things are added into the cobweb box, the cover is immediately used for covering the operation opening to prevent the Chinese wolf spider from climbing away.
The culture soil is added into the cobweb case, the height 4 of the added culture soil is 2/3 of the depth of the cobweb case, and the water container 6 is placed on the culture soil. A wooden stick is used for assisting in opening a hole 7 in the culture soil, the hole direction is vertical downward, the hole diameter is 2-3cm, the depth is 3-4cm, and the surrounding soil is compacted to prevent collapse. The auxiliary hole opening can reduce the hole building resistance and energy consumption of the Chinese wolfs spider.
The number of the water containers can be 2, a clean plastic bottle cap can be used, and pure drinking water is added to 2/3 height of the bottle cap.
(3) Feeding and management of Chinese wolfsbane
Carefully clamping the collected Chinese pennisetum into the spider box in the step (2) from the operation opening by using tweezers. The food is put in every 3-4d and the water in the water container is replaced. Among them, cockroaches and crickets are more preferable as food. Cricket is very soft in its outer shell and easy to prey. Cricket and cockroach are not strong in aggressivity, do not cause any damage to Chinese pennisetum, and the activity of the cricket and cockroach is strong, so that the predation interest of Chinese pennisetum is easy to arouse. The bread worm is also sufficient, but the bread worm contains more fat and is slowly digested, and the head of the bread worm is pinched off when the bread worm is thrown to eat, so that the bread worm is prevented from being drilled into soil and is difficult to be caught by the Chinese pennisetum. The wild mantis is directly caught from a brook river, is easy to infect the iron nematodes, can affect the Chinese langspider, and is not suitable for being used as food, so when the mantis is fed to the Chinese langspider, the wild mantis is fed to indoor cockroaches. For Chinese pennisetum with body length greater than 2cm, 2-3 cockroaches of 1-2cm, crickets of 1-2cm or bread worm of 1-1.5cm (with head removed) are thrown every time. For Chinese pennisetum with body length less than 2cm, 2-3 crickets (0.5-1cm), cockroaches (0.5-1cm) or bread worm (0.5-1cm) treated by removing head are thrown.
Before the Chinese pennisetum molting (the body color generally becomes light), water and food are added into the container in advance, so that the Chinese pennisetum molting is prevented from being disturbed during the molting period to avoid being frightened and normal life activities being influenced. Dead food residues (worms) and excrement such as feed (worms) are taken away at once, so that the influence of breeding mites on the health of the langoustine is avoided, and even death is avoided.
The environment temperature of China pennisetum is 20-30 ℃. The spider breeding box is placed indoors for breeding Chinese pennisetum at room temperature, and can not be exposed to direct sunlight. Keeping warm in winter, wrapping a layer of cotton on the cobweb box, placing the cobweb box on a pet climbing heating pad, setting the temperature of the heating pad to be 25 ℃, and placing the cobweb box in a dark and ventilated place indoors in summer.
Only one Chinese pennisetum is raised in one container as far as possible without mixed culture, otherwise, struggle and killing are easy to arouse. When the Chinese pennisetum is just put into the cobweb box, a certain adaptation time is provided, and the Chinese pennisetum can quickly climb in the cobweb box at first. Feeding can begin when it begins to spin or no longer crawl rapidly in the container, indicating that it has more or less adapted to the environment of the spider cage.
When feeding the Chinese pennisetum, long-point chopsticks or tweezers are used for assisting, and the Chinese pennisetum is not directly fed by hands so as to avoid being bitten by the Chinese pennisetum. The toxicity of the Chinese pennisetum causes no great harm to human beings, if the Chinese pennisetum is bitten, the Chinese pennisetum is immediately disinfected by alcohol and bandaged by gauze, and if discomfortable symptoms such as red swelling, pain and the like occur, the Chinese pennisetum is preferably immediately hospitalized.
In the cultivation process, the proper humidity of cultivation soil is ensured. When water is added each time, the water is sprayed on the wall of the container along the vent hole or the operation hole by a watering can, so that the water naturally flows down along the wall of the container. A little water is sprayed on the surface of the soil, but the soil is still kept in a dry state. This condition is appropriate when the subsoil (about soil height 1/5) is wet. The watering period is once every 3-4 days. Although food residues and excrement are cleaned regularly, the soil still has inevitable residues, and the culture soil in the spider cage should be replaced every 3-6 months (the replacement of the soil is not easy to work, so that the spider cage is prevented from being frightened and needs to adapt to a new environment again), and the method is the same as the step (1).
The reason for selecting the above-mentioned moisture content for the soil is: the soil with the humidity can not be too viscous, and is beneficial to the activity of Chinese pennisetum. Meanwhile, the water cannot volatilize in a short time (3-5 days), and frequent water addition can be avoided.
By applying the method, the weight of the Chinese pennisetum with the body length of more than 2cm is increased by 9-12mg in one month, and the survival rate is more than 95%. The weight of Chinese pennisetum with body length less than 2cm can be increased by 5-8mg in one month, and the survival rate is above 90%.
The invention mainly researches the water adding amount and the type and the amount of fed food. See examples 1, 2, 3, 4 and 5 for an optimized comparative experiment.
Example 1
The indoor raising method of the Chinese pennisetum comprises the following steps:
(1) preparation of cultivation soil
Sterilizing the coconut soil without impurities in an autoclave to obtain the culture soil, and sterilizing for three times, wherein one hour is used for each sterilization.
(2) Preparation for raising Chinese pennisetum environment
Referring to fig. 1, the spider feeding box is made of a white colloid plastic box, and the specification of the spider feeding box is as follows: height 1, length 2, width 3 each 10 cm. The cobweb-cultivating box should not be too large or too small, too small is not good for the activity of Chinese wolf spider, and too large is not good for controlling temperature and humidity. The vent holes 5 are located at the upper 1/3 part of the side surface of the cobweb box, four side surfaces are arranged, each side surface is 12, and the diameter is 0.5 cm. The interval between adjacent vent holes 5 is 1cm, and the distance from the side edge is 1cm, so that the Chinese pennisetum can obtain sufficient oxygen by manufacturing the vent holes. A circular operation opening 8 and a cover (not shown) matched with the circular operation opening are arranged at the top of the spider cage, the diameter of the operation opening is 3cm, and food and soil can be added from the operation opening. The cover of the operation opening is made by cutting a screen window into a proper size, and after all things are added into the cobweb box, the cover is immediately used for covering the operation opening to prevent the Chinese wolf spider from climbing away.
The culture soil is added into the cobweb culture box, the height 4 of the added culture soil is 2/3 of the depth of the cobweb culture box, and 2 water containers 6 are placed on the culture soil. The wood stick is used for assisting in opening the hole 7 in the culture soil, the hole is inclined downwards, the diameter of the hole is 3cm, the depth of the hole is 3cm, and the surrounding soil is compacted to prevent collapse.
The water container can be a sterilized plastic bottle cap, and pure drinking water is added to 2/3 height of the bottle cap.
(3) Feeding and management of Chinese wolfsbane
Carefully clamping the collected Chinese pennisetum onto the spider cage from the operation opening by using forceps. Food is put in every 4d and the water in the water container is replaced. For Chinese pennisetum with body length greater than 2cm, 2 indoor raised cockroaches of 1.5cm are thrown every time. For Chinese pennisetum with body length less than 2cm, 3 cockroaches raised in the room just hatched by 0.8cm are thrown every time.
Before the Chinese pennisetum molting (the color generally becomes light), water and food are added into a container in advance, so that the food residues and excrement such as the Chinese pennisetum molting, dead feed (worms) and the like are not disturbed as much as possible during the molting process and are immediately taken away.
The spider breeding box is placed indoors for breeding Chinese pennisetum at room temperature, and can not be exposed to direct sunlight. Keeping warm in winter, wrapping a layer of cotton on the cobweb box, placing the cobweb box on a pet climbing heating pad, setting the temperature of the heating pad to be 25 ℃, and placing the cobweb box in a dark and ventilated place indoors in summer. Only one end of the Chinese pennisetum is raised in one container, when the Chinese pennisetum starts to spin in the container or does not climb quickly any more, the Chinese pennisetum is proved to be almost suitable for the environment of the cobweb box, feeding can be started, and during feeding, long-point chopsticks are used for assisting.
In the cultivation process, the proper humidity of cultivation soil is ensured. When water is added each time, the water is sprayed on the wall of the container along the vent holes by a watering can, so that the water naturally flows down along the wall of the container. A little water is sprayed on the surface of the soil, but the soil is still kept in a dry state. This is the case when the subsoil (soil level 1/5) is wet. The watering period was once every 3 days. Although food residues and excrement are cleaned regularly, the soil still has inevitable residues, and the culture soil in the spider cage should be replaced every half year (the soil replacement is not easy to work, the scare is avoided, and the new environment needs to be adapted again), and the method is the same as the step (1).
By applying the method, the weight of the Chinese pennisetum with the body length of more than 2cm averagely increases by 12mg in one month, and the survival rate reaches up to 100 percent. The weight of the Chinese pennisetum with the body length less than 2cm averagely increases by 8mg in one month, and the survival rate is as high as 100 percent.
Example 2
The present embodiment is different from embodiment 1 in that:
for Chinese pennisetum with body length greater than 2cm, 3 crickets of 1cm are thrown in each time. For Chinese pennisetum with body length less than 2cm, 3 crickets which are just hatched and are 0.5cm are thrown in each time. The rest steps are the same.
By applying the method, the weight of the Chinese pennisetum with the body length of more than 2cm averagely increases by 10mg in one month, and the survival rate reaches up to 100 percent. The weight of the Chinese pennisetum with the body length less than 2cm averagely increases by 7mg in one month, and the survival rate is as high as 95%.
Example 3
The present embodiment is different from embodiment 1 in that:
for Chinese pennisetum with body length greater than 2cm, 2 Tenebrio molitors with body length of 1.2cm are thrown (to remove head) each time. For Chinese pennisetum with body length less than 2cm, 3 Tenebrio molitor of 0.7cm are thrown at a time. The rest steps are the same.
By applying the method, the weight of the Chinese pennisetum with the body length of more than 2cm averagely increases by 9mg in one month, and the survival rate is 95%. The weight of Chinese pennisetum with body length less than 2cm can averagely increase 5mg in one month, and the survival rate is 95%.
Example 4
The present embodiment is different from embodiment 1 in that:
in the culture process, water is directly sprayed on the soil surface of the culture box by a watering can, so that the soil is completely wet, and the bottom of the culture box has accumulated water. The watering period was once every 3 days. The rest steps are the same.
By applying the method, the viscous muddy water inhibits the action of the Chinese pennisetum, and the Chinese pennisetum moves very slowly in the breeding box and dies after one week.
Example 5
The present embodiment is different from embodiment 1 in that:
when water is added each time, the water is sprayed on the wall of the container along the vent hole or the operation hole by a watering can, so that the water naturally flows down along the wall of the container. A little water is sprayed on the surface of the soil, but the soil is still kept in a dry state. When the soil is completely wet to a height of about 1/2 deg.C, the addition of water is stopped. The watering period was once every 3 days. The rest steps are the same.
By applying the method, the Chinese pennisetum activities in the breeding box are slow, the survival rate of the Chinese pennisetum with the body length larger than 2cm is 50%, and the survival rate of the Chinese pennisetum with the body length smaller than 2cm is 60%.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
