&Guangzhou Design Fee Release&#[E-mail_Xiao Zhang:] I wish you success and success. , wealth, source, wide, advance, body, body, health, health, cooperation, work, pleasure, pleasure, it is understood that in recent years, due to the large-scale promotion of straw return technology, Spodoptera exigua has become the Huanghuaihai corn Major diseases in growing areas. This is because Spodoptera exigua adults and larvae like concealed and moist environments. After wheat straw is returned to the field, it becomes the best environment for adults to hide, lay eggs and move larvae. Moreover, there has been a lot of rain this year, which has objectively aggravated the occurrence of this pest.
Relevant people in Denghai Seed Industry said that in order to prevent and control this pest, the company has conducted key training for seed sales personnel, and organized them to vigorously publicize the "three ways to prevent and control this pest" to farmers when selling improved seeds and providing after-sales services. Key points: First, secondary coating of seeds to enhance resistance. The second is to try to clean up the straw around the corn to destroy the growth environment of Spodoptera exigua. Third, once pests occur, we must seize the best control period at the end of the month and the beginning of the month. You can choose any one of chlorpyrifos, beta-cypermethrin, acephate and other chemicals, and spray as soon as possible. The spray area is the base of the corn seedlings, or you can mix it with Sprinkle poisonous soil at the base of corn seedlings. If the prevention and control is not in place during this period, the larvae of Spodoptera exigua will enter the gluttony period, which will pose a serious threat to the growth of corn.
The interview found that cleaning up the straw around corn as much as possible is the most direct and effective technology to prevent and control this pest. After the wheat harvest, farmers can bundle the wheat straw and transport it out of the field. They can use a stubble cutter to crush and compact the wheat stubble and wheat straw before sowing. They can use a corn seeder with a ridge clearer for sowing. &In short, as long as there is no straw around the corn, the occurrence of pests can be basically eliminated. &rSaid Wang, the director of the Plant Protection Station of Laizhou Agriculture Bureau.
This approach has been confirmed in practice. According to people in the Denghai seed industry, this year, many places in Shandong have promoted the practice of bundling wheat for sale, and the Spodoptera exigua pest has basically not occurred. Moreover, through the promotion in the past few years, farmers generally have methods that suit them, and most of them can clean up the straw around the corn as much as possible.
Dunhuang seed industry has avoided insect disasters by relying on its variety strength
Tens of thousands of acres of corn armyworm broke out in Weinan, Gansu
Reporter Miao Yi
Heyang, Huayin, and Tongguan in Weinan, Shaanxi Corn armyworm outbreaks occurred across tens of thousands of acres in other counties and cities. On March 1, when the reporter learned of the news, he immediately called Fan Wugang, a senior agronomist at the Plant Protection Station of Heyang County Agricultural Technology Center who had interviewed him.
&I am preventing armyworms in a cooperative. The affected area here is 500 to 600 acres. Using drones to spray pesticides, the control can be completed in one day. &rYou can imagine how anxious Fan Wugang has been and how busy he has been since the corn armyworm attack occurred at the end of the month. &Although the leaves of each plant in the affected plot were damaged to varying degrees, with about one to one head of armyworm per plant, fortunately, the prevention and treatment was in place in time, but the harvest was far from complete. &r
Compared with the affected areas, Yu, a corn farmer in Heyang County, seems to be much luckier. It turns out that he spent a lot of money this year (a bag of seeds is 1% more expensive than ordinary seeds) to buy "Fuliang Jixiang No. 1" from Gansu Dunhuang Seed Industry Co., Ltd.
According to Gao Zerun, sales manager of Shaanxi District of Gansu Dunhuang Seed Industry, this year, of the more than 10,000 acres of corn planting area in Heyang County, 10,000 acres have been planted with "Fuliang Jixiang No. 1". &Since the outbreak of corn armyworm at the end of the month, we have paid close attention and conducted telephone follow-up interviews with dealers. So far, we have not received any news from growers reporting that corn has been harmed by armyworm. &r
According to Fan Wugang, armyworms mainly eat corn leaves. After an outbreak, if the control is not timely, all the leaves will be eaten quickly, leaving only the stalks, which may lead to a failed harvest. However, this corn armyworm outbreak is so rapid and covers such a large area. How did "Fuliang Jixiang No. 1" survive?
Yu Liang, sales manager of Gansu Dunhuang Seed Industry, told reporters that "Fuliang Jixiang No. 1" is the company's main insect-resistant variety this year. &The variety itself has good insect resistance properties. In addition, in order to prevent problems before they occur, the company has spent a lot of money to improve the overall configuration of this variety. &rYu Liang said, &rWe use the best seed coating agent currently on the market (general seed coating agents cost . yuan to . yuan per kilogram, but this one costs as much as yuan per kilogram). &r
Compared with .yuan and .yuan, in addition to the more than double price difference, especially in the case of insect disasters, it further reflects the seed companies' continuous improvement of varieties.
&As the saying goes, in good years, you should look at the variety, but in bad years, you should look at the potential. &rYu Liang said, "Agriculture requires sentiment. In the face of insect disasters, we not only need sentiment, but also responsibility. &r
The trillion breeding industry has chosen us, and the service must keep up
Heavy rain in Hebei caused floods
Our reporter Li Jie
&The heavy rain on October 1 caused floods, and the corn fields were full of Water, I was so anxious that I didn’t sleep well for several nights! &r
On February 1, Zhang Huqun, a major grain grower in Zhangerzhuang Village, Huangsi Town, Xingtai County, Hebei Province, told reporters that he has planted acres of corn this year, more than half of which are planted with "Liyu", and many acres more. An American variety. "Liyu" appeared to be slightly lodging during the bell mouth period. Under the on-site technical guidance of the manufacturer's technicians who arrived in time after the rain, it has now stood upright without affecting later production. However, another American variety suffered from large-scale inversion and almost lost its harvest.
Zhangerzhuang Village is located 1km west of Xingtai City, in the hilly area of the Taihang Mountains. It is already the first year for Zhang Hu to breed "Liyu". He introduced that this variety has well-developed roots, strong plants, and an ear length of about 1 meter. It is drought-resistant and flood-resistant, and is suitable for local planting. Last year, it produced more than 100 pounds per mu.
During the summer sowing this year, Yang Bo, a technician from Hebei Zhao Breeding Industry Co., Ltd., the manufacturer of "Liyu", came to Zhang Huqun's field and asked him to reduce the amount of corn sown from the original number of plants per mu to plants per mu. After the heavy rain, I came to the village again to provide on-site guidance on drainage and pest control. The timely service made Zhang Huqun confident about this year's autumn grain harvest. He said, "With good moisture and sufficient base fertilizer, this corn may yield a pound per mu!" &r
In Northeast Qi Village, Yizhong County, Hebei Province, Zhai Zhenhe, a multi-year-old grain farmer, said that he planted more than 1 mu of "Liyu" and there were no disasters such as lodging during the heavy rain. The corn in the grain-filling period grew well. . Zhai Zhenhe said: "Seeds have their own regional characteristics. I think this variety is suitable for growing in the hills and plains east of the Taihang Mountains, and the yield is relatively stable." &r
&When farmers choose our seeds, tracking services must be in place. Cai Qinggang, the product service department of the Seed Industry Company, said that for seed dealers, all farmers planting more than 1 mu of Liyu, and representatives of regional farmers who plant in large areas, they will make one-on-one phone calls to remind farmers within one week before sowing. Sowing precautions. At the same time, on the company’s WeChat platform, cultivation and management techniques for different growth stages of varieties are released in a timely manner. Especially since the middle of this month, heavy rains have fallen in most areas of Hebei, causing heavy lodging of summer corn. The company organized service personnel to go to various disaster-stricken areas to understand the disaster situation, give on-site lectures, distribute technical measures "clear papers", and guide farmers to carry out services. Disaster relief activities.
Zhao Yujin, chairman of Hebei Zhaoyu Seed Industry Co., Ltd., introduced that the seed industry company was established in March 2018. It is centered on corn seeds and integrates seed scientific research, production, processing, marketing and service. Among them, "Liyu" This year's promotion area is more than 10,000 acres, and the annual promotion area is more than 10,000 acres. It is mainly planted in major corn-producing areas such as Jiangsu, Anhui, and Hebei
