How effective is the Jiaduo frequency-vibration insect-killing lamp at trapping and killing the rice stem borer?
The rice stem borer is one of the important pests in rice production in Wuchang City. In recent years, with changes in rice varieties and warming climate conditions in our city, the occurrence and damage of the rice stem borer have become increasingly serious. According to this autumn's survey, for certain varieties in Wuchang, the average number of insects per 100 steps per mu reached more than 20,000, with the highest in key outbreak areas reaching 60,000, and in some cases more than 100,000. Such insect numbers are rare in history, whether domestically or abroad. In order to further control the damage of the rice stem borer, explore new approaches to its control, and reduce pesticide pollution of rice. This year our city set up at Sun Guanghao's field in Lianhua Village, Wuchang Town

Introduction to the Characteristics and Traits of the Jiahe Zaozhan Rice Variety
Jiahe Zaozhan was developed by the Rice Breeding Group of the School of Life Sciences at Xiamen University through a combination of sexual hybridization and the original "rice mature pollen irradiation mutagenesis technique" (which won the Second Prize for Science and Technology Progress of Fujian Province), and was bred through the pedigree method as Fujian Province's first late-maturing early-season new variety meeting the national quality standard for edible rice. It was recognized by the organizing committee of the '99 China International Agricultural Exhibition as a "Famous Brand Product" early-season variety and won the Second Prize for Science and Technology Progress of Xiamen City in 1999. Its cross combination: E94/Guangdong Dalizhong.

How to treat rice damaged by metsulfuron-methyl herbicide injury?
Remedial measures: After transplanting (or throwing) seedlings in fields where herbicides have been applied, field inspections should be strengthened. When herbicide injury occurs, measures must be taken immediately to reduce losses. 1. Re-transplant (re-throw) seedlings: If diagnosis confirms severe seedling injury, with more than 80% of seedlings yellowed and some withered, seedlings must be gathered for immediate re-transplanting (re-throwing). Method: First drain the field water, lightly harrow once, then drain the muddy water, then level the field and transplant (throw) seedlings. In recent years, sowing and transplanting (throwing) seasons have been advanced by 7-15 days compared to traditional seasons. From discovery of injury to re-transplanting is generally 5-10 days, so the seasonal conflict is not prominent. 2. Strengthen fertilizer and water management and intertillage: For fields where injury is found, first drain the field water that has been treated with herbicide and irrigate with fresh flowing water. Next, perform intertillage to break up the original herbicide liquid layer and turn the herbicide adsorbed by the surface soil into deeper soil, reducing the effect of the herbicide on rice roots. 2-3 days after intertillage, apply 2-4 kg of imported compound fertilizer per mu to promote root growth and leaf development and accelerate growth. 3. Apply rooting agent: After draining, intertilling and fertilizing, it is best to apply 200 kg per mu of rooting agent ABT at a concentration of 200 mg/kg, which has a good effect on promoting roots. The number of roots can increase by 25%-40%, growth speed accelerates, and the sufficient seedling stage is delayed by only 5-7 days.
