Located in the Yutian high-quality rice production base in Chunhua Town, in order to allow the bullfrogs that eat the pests to have a habitat, they have specially ditched water in the fields and planted beans.
After the rice was planted for more than 10 days, a group of Trichogramma and bullfrogs were stocked in the fields to allow them to grapple in the farmland. In the twinkling of an eye, the rice planthoppers, aphids, leafhoppers, and other pests attached to the rice were all integrated. These "rice guardian" mouthpiece.
Recently, the reporter arrived at the Yutian High Quality Rice Production Base in Chunhua Town. The 2000-mu high-quality rice used to control pests through the use of biological techniques such as the stocking of Trichogramma, bullfrogs, and insecticidal lamps. It did not hit a drop of pesticide and the rice could be sold. The high price of 48 yuan / kg, and supply in short supply.
20,000 Trichogrammaes per acre can eat 80% of Ascaris eggs
At the high-quality rice production base in Yutian, the reporter saw that every ten meters in the paddy field had a piece of bamboo in it, and a bamboo paper cup with a cup facing down hung on the bamboo, much like a “little lanternâ€. "This paper cup is the home of the Trichogramma. There are a lot of Trichogramma eggs." Hu Qingxi, a villager working in the fields, told reporters that since the introduction of Trichogramma into the rice fields the year before, whether it was Early rice or late rice, control of locust no longer hit pesticides, and the effect is even better than the fight drugs.
“The Trichogramma is very small and difficult to see with the naked eye.†Seeing the reporter constantly flipping through the paper cups storing the eggs, Zhang Junjie, the person in charge of the base, quickly explained with a smile. According to him, Trichogramma species is a kind of parasitic beneficial insect, and its adult body length is only 0.5 -1 mm, but it can make full use of its preference to parasitize the eggs on the eggs of the ascarid and absorb the nutrients of the eggs. To kill locust eggs, in mid-May and mid-August each year, the eggs with the eggs of Trichogramma bees are hung in the field with bamboo and pests are prevented at the source. It is understood that this control technology can kill at least 80% of the locust eggs.
"In order to prevent 100 insecticidal insect pests at the source, the base also used insecticidal lamps." Zhang Junjie said while pointing at the insect poles on the field poles. The reporter saw that these insect killers, like the “Lantern,†together with the “little lanterns†in the fields, were very interesting under the backdrop of green and green seedlings.
Bullfrogs and crops growing in sync with growing field pests
Walking in the field of the rice plant, the reporter suddenly saw a rather special small frog. When he just picked up the camera and prepared to shoot, it suddenly jumped away. “This is the bullfrog that we used for stocking specifically to stockpile insects.†Zhang Junjie told reporters that this kind of bullfrog is very vigilant. As soon as someone is close, he will immediately jump away.
According to him, this kind of bullfrog is not the same as the bullfrog used for feeding, but it is smaller, and it feeds on rice pests other than grasshoppers such as rice planthoppers and leaf-worms. "With these guards in the field, pests and diseases are basically gone." Zhang Junjie said with a smile, in order to give this bullfrog a habitat, it is necessary to ditch water in the fields and plant some shade on the ditch to shade it. The vegetables and beans allow them to have a rest after work.
It is understood that the base does not make a drop of pesticides during the entire 2000-acre high-quality rice production process. Pest control is mainly based on biological control, supplemented by other physical controls. After the high-quality rice produced by it is processed into rice, it can be sold at a high price of 48 yuan/kg, and supply falls short of supply.
