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.

New rice varieties hit the market: Jiangsu Mingtian Seed Industry launches new varieties
Nanjing 44, formerly known as "Ning 4009", is an early-maturing late japonica rice variety systematically bred from Nanjing 38 by the Institute of Food Crops, Jiangsu Academy of Agricultural Sciences, and was developed in 2004. It is suitable for planting under medium-to-high fertility conditions in the areas along the Yangtze River and southern Jiangsu. From 2005 to 2006, it participated in the Jiangsu provincial regional trial. The two-year average yield per mu was 588.1 kg, and the 2006 production trial average yield per mu was 621.9 kg, an increase of 7.1% over the control. The number of effective panicles per mu is about 190,000, the number of filled grains per panicle is about 130, the seed-setting rate is

Rice cultivation in cold regions requires water-saving irrigation, selection of improved varieties, making the most of accumulated temperature, and growing strong seedlings
Heilongjiang Province is located in a high-cold region, where heat and water resources are relatively scarce, annual atmospheric precipitation is extremely unevenly distributed, spring is windy with little rain, and drought is quite severe. The author discusses how to achieve water-saving, high-quality, and high-yield rice cultivation in cold regions. 1. Selecting excellent varieties is the prerequisite for ensuring high-quality and high-yield rice. The varieties that rice farmers plant directly affect the quality and yield of rice. Therefore, in production, varieties with a suitable maturity period, excellent quality, stable and high yield, and strong stress resistance should be selected. First, select varieties that have passed national approval, been named, and promoted, which can ensure relatively stable rice traits, steady and rising yields, and safe and reliable use; second, introduce varieties with suitable maturity periods according to different accumulated temperature zones, and never introduce varieties across zones; third, pay attention to seed quality, and select first-grade improved seeds with a purity above 98%, a germination rate above 90%, and a moisture content no higher than 14% for production use; fourth, purchase seeds from nationally certified seed companies, research institutes, and agricultural colleges, and eliminate blind planting; fifth, in actual planting, unify varieties as much as possible, plant in contiguous fields, form scale, and achieve industrialized planting.

Hanyou No. 3 rice saves water and resists drought, high-yielding and easy to grow
Rice is high-yielding, but afraid of thirst; upland rice is drought-tolerant, but its yield is slightly inferior. Shanghai rice experts ingeniously merged the advantages of the high yield of rice and the drought tolerance of upland rice into a single grain of rice seed, breeding the world's first water-saving and drought-resistant hybrid rice, "Hanyou No. 3". The author recently saw the mature "Hanyou No. 3" bent over from "exhaustion": each panicle bears 110 grains, and the yield per mu is better than that of conventional rice, while the rice field saves more than 50% of water. The new rice can go on the market in Shanghai at the end of the month. According to testing by a professional department, the grain quality of "Hanyou No. 3" reaches the Ministry of Agriculture's second-grade high-quality rice standard, and

Southern Rice Production Situation This Year and Market Trend Outlook
According to monitoring by meteorological departments, rice growth and development are good, but with the excessive rainfall and the continuous migration of pest sources from abroad, the pest and disease situation in southern production areas is severe, forming a certain adverse impact on rice yield and quality in the later period. At the same time, driven by the sharp rise in prices of agricultural products such as edible oil and pork, combined with a partial recovery in rice demand, domestic rice prices have recently shown an overall trend of steady increases. The specific situation is briefly analyzed as follows: 1. This year's new rice production situation in the south 1. Favorable factors support
