1. Turtle Pond Construction Turtle ponds should be built in a secluded area and divided into three areas. Rely on the pool side or pool corner for drinking water and bathing area, the area is 10% to 30% of the total area, water depth is 10~30cm, and the water outlet is inclined; the bathing area is the feeding trough, and the area accounts for 10%~20%. Smooth, set the drain to communicate with the outside world, so that regular flush; other spawning and rest areas, with sandy loam as well, on which vegetables can be grown. Turtle ponds generally tilt toward the bathing area, and each area is connected with a gentle slope. Around the pool, a 50-cm-high anti-escape wall is built. The wall base is about 25 cm deep, and the entrance and exit are designed to prevent escape.
2, disinfection and stocking
2.1 Turtle Pond Disinfection 10 to 15 days before stocking. Guichi drinking water bathing area and feeding trough should be completely disinfected with quicklime or bleaching powder and other drugs. Spawning and rest areas should be sprayed with 1% bleaching powder or dry lime to disinfect. The new pool is soaked in water for 2 to 3 times to remove alkali before use.
2.2 Selection of adult turtles The source of the yellow-rimmed shell turtle mainly relies on the acquisition of wild turtles. The turtle should be purchased from April to August each year. During this period, the number of turtles is high and the price is low. It should be domesticated and raised; from November to March of the following year, the turtles are in During hibernation or imminent hibernation, it is difficult to observe turtle activity, eating, defecation, etc., and it is difficult to grasp the survival rate of turtles. Picking turtles can start from the turtle's appearance and faeces. Wild turtles are lean, timid, and have many folds on their extremities. Their turtles feel that the turtles are lighter. Healthy turtles have eyes and eyes, no white spots on the cornea, no blood in the nose and mouth, and no mucus secretion. Skin and carapace, plastron without damage, ulceration. The limbs can prop themselves up when crawling. After being frightened, you can escape immediately. The excrements of healthy turtles are lumps and wrapped in albuginea. If the feces are egg white, blood red, light green, etc., it is abnormal.
2.3 Stocking Newly purchased turtles must be bathed with 2.5% saline or 20mg/L potassium permanganate solution for bathing. Juvenile tortoise stocking density of 40 to 50 / square meters, hatchlings 20 to 30 / square meters, turtles stocking more than 200g 10 to 15 / square meters, breeding turtles 2 to 5 / square meters.
3, daily management daily feeding to peel skin fish, snail meat, lean pork based, but also feed breadworms, cockroaches, snails, etc.; best domesticated feed sturgeon feed or stoma feed. In order to ensure the balance of nutrients and bright body color in the turtle body, some fruits or fruits can be fed regularly, or some complex vitamins can be fed directly. The feed should be fresh and tasty, especially the young turtle feed must be fine, tender and soft. Fresh feed or lumps should be placed in the trough, granular yellow trout can be placed in the trough, but also on the surface, but the bait should be removed in time. The spring and autumn seasons are generally fed before noon, and fed every 2 days. When the temperature is high in the summer, it is fed after 5 pm and fed once a day. The amount of feed should be determined according to the season, weather, feed quality, turtle size, etc., generally 1% to 5% of the turtle body weight.
The residual bait in the trough should be rinsed in time. In the spring and autumn seasons, the water in the drinking area should be changed regularly. During the summer heat season, the water should be changed frequently. The water change should be performed before the feeding. The temperature difference between the water should not be higher than 3-4. °C. When it rains, check whether the drainage of the turtle pool is smooth. Take an inspection every day to check the turtle's activities and feeding conditions and find out if problems are solved in time.
In early November each year, the turtle gradually enters hibernation due to a drop in temperature. Adult turtles and probiotics that grow outdoors can overwinter in the original pool. At this time, a layer of hay should be placed in the active area; hatchlings and hatchlings reared outdoors are the most suitable. It is better to go into the indoor wintering pond for the winter, or cover the Plastic Film Greenhouse in the upper part of the turtle pond for winter. During hibernation, care should be taken to maintain the soil moisture in wintering areas.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated Irrigation System
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
