Hongxiang Pear is a new species of red pear. In recent years, the development momentum in Hengshui City has been strong. The cultivation area of ​​the city is over 30,000 mu. Due to the fact that red sachets are generally not bagged with fruit and their growth period is long, they are vulnerable to various pests and diseases. The pollution-free control technology of Hongxiang Pear is now described as follows:
First, use Jiaduo insecticidal lamp to kill insects
Hongxiang Pear Fruit is vulnerable to insect pests such as borers, stink bugs, chafers, etc. These pests have the characteristics of rapid transfer rate, and the control of pesticides is difficult. The use of Jiaduo Frequency Trembler lamp can kill the heartworms, stink bugs, etc. every night. There are more than 2,000 pests and the insecticidal effect reaches 70%, which can effectively control the above pests. Jiaduo vibration type insecticidal lamp, on the one hand, has a high technological content and can utilize the characteristics of insect pests such as phototaxis, wave, color, and taste to set the light wave within a specific range, use light at a short distance, and use boga flavor and taste at a long distance. To lure the adult, the lamp is contacted with a frequency-vibrating voltage network to make the insect fall into the bag to kill the adult and control the purpose of the damage. On the other hand, it selects the light source, wavelength, and band that can avoid the natural enemy habits. Protect natural enemies well. Hong Xiang Pear Orchard generally hangs a pest killer lamp every 40 mu. The height of the hanging lamp is 4-5 meters. The light is turned on at 6 o'clock every night and turned off at 6 o'clock in the morning. Each lamp can be used continuously for more than 4 years.
Second, the suspension lure trap kill pear pear borer
The pear borer is the most important pest of Hongxiang Pear. If the control is unfavorable, it may result in the loss of pear orchard. The 4-5 generations of this worm occur every year and it is difficult to prevent and control it from generation to generation. In order to accurately understand the occurrence and harm of the small carnivorous insects in Hongxiang Pear Garden, the pear lizards were used to predict and control the pear carnivorous insects. Good control effects were achieved, and natural enemies were effectively protected and utilized. A good measure of pollution of fruit.
Method: Take a 20 cm diameter water basin, use a thin wire slightly longer than the diameter of the basin to cross a lure placed in the center of the top of the basin and fix it so that the lower edge of the lure is flush with the surface of the basin to prevent The rainfall basin is full of water and soaking the wick. After doing a good job, the pelicans will be hung on the shady side of fruit trees to prevent direct sunlight from lures. The height of the suspension is about 1.5 meters away from the ground. After the basin is installed, add water to the basin and add 0.2% detergent to the water. The amount of water added is 1 to 1.5 cm from the lower edge of the lure. Place a density of 5-6 grains per acre. The placement time began at the end of June and the pear borer worm started to end in mid-September before it began to harm the pear fruit.
Third, the use of the latest pollution-free chemicals
1. Use bionic agents to control pests. The use of non-environmental biomimetic agents — 5% chlorophenoxycarb, can effectively prevent and harm the main pests of Hongxiang Pear. 5% chlorophenoxycarb is a high-efficiency, low-toxicity, green, environmental-friendly and environmentally friendly product. It is the preferred pesticide for producing pollution-free foods and green foods. Its toxicity is even lower than that of salt. This medicine is the latest bionic pesticide, which regulates the growth of insects and affects the molting process of insects. When it acts on pests, it can kill the eggs, larvae and adults of pear pests. Spraying 3-4 times the concentration of 1500 times a year liquid, can effectively prevent pear wood worms, Cornell mealybugs, carnivora, aphids and other pests, while the safety of natural enemies.
2. Biological source bactericides prevent diseases.
1 Pyrimopyromycin against pear disease. Pure Bio-Bacterial Fungicide—Tybolin (4% pyrimidactin) is a new type of high-efficiency pure biocide for cytosine nucleoside peptides. It is the latest achievement of the national “863†project. The crop is composed of fungi, bacteria, and viruses. Many kinds of diseases caused by it have a strong treatment and control effect, and the control effect is above 90%. The use of 4% pymidemycin 500 times to prevent diseases such as scab, ring rot and other diseases, in May, July, August, foliar spray, sprayed 2-3 times in a row, the control effect of 95%.
2 matrine to prevent pear disease. The specific components of matrine are contacted and stomach poisoned to paralyze the central nervous system of the pest, which in turn causes the protein of the insect body to coagulate, block the stomata of the insect body, and cause the insect to suffocate and die. Matrine not only kills insects, but also effectively kills all kinds of fungi and bacteria in fruit trees. It also contains many organic substances and trace elements and is easily absorbed and transformed by plant crops. With 2.0% matrine aqueous solution (special for fruit trees) 1200 times, in early May, early June and early July, the harms of Pyrosphaeridae, Red spider, Pyriacidae, Tetranychus urticae, and Pear tree borer could be effectively controlled.
Brand computer chips, dual-frequency integrated circuits, cross-magnetic induction detection, bringing higher accuracy, reliability and stability. 2. Automatic control system, using special magnetic materials and unique technology, the detection accuracy of the probe is particularly high, and the accurate position of the broken needle is displayed in 8 detection areas. 3. Dual probe design, double detection function, higher safety performance, compared with other types of needle detectors, at the same detection height, the sensitivity is increased by 10%. 4. Automatic detection, automatic induction, automatic stop when no detection is needed, 0-10 sensitivity adjustment, when there is a broken needle, the conveyor belt automatically stops and returns backwards. 5. With a counting function, it can count the number of qualified or unqualified products. 6. It has two alarm modes: sound effect and light alarm. 7. Luxurious appearance, novel style, time-saving and power-saving, simple operation
