Get twice the result with half the effort with half the effort to control rice diseases and pests in winter
In winter, rice diseases and pests are dormant: pests stop feeding and germs stop infecting. If farmers seize this favorable opportunity to carry out prevention and control, they can achieve twice the result with half the effort. First, deal with diseased straw. Diseased rice straw is the overwintering place of pathogens of many diseases, such as bacterial leaf spot, bacterial blight, rice blast and so on, and is the main source of infection in the second year. Before the end of March, farmers can compost diseased rice straw at high temperature, or for feed and fuel treatment, which can greatly reduce the number of bacteria. For the diseased rice that can't be disposed of before the end of March

Effect of low temperature chilling injury on Rice and its Preventive measures
Rice chilling injury means that rice suffers from the influence of low temperature below the lowest critical temperature, which leads to the abnormal growth and development of rice and the reduction of rice yield. According to the different period of injury, it can be divided into delayed chilling injury, obstacle chilling injury and mixed chilling injury. 1. Types and characteristics of rice chilling injury 1. Delayed chilling injury rice in vegetative growth period, sometimes including reproductive growth period, suffers from lower temperature for a long time, weakens the physiological activity of rice plant, delays heading and flowering, and cannot be fully filled.

Rice fungicide with low cost and high efficiency
Invest 20 yuan and return 50 yuan. Do you do such a good deed? Last year, after the big grain growers in Shaoxing, Anji and other places used "love seedlings" when growing rice, they tasted such sweetness, and rice generally increased by about 10%. At present, it is the early rice medicine season, and they are busy buying this new medicine with high return and applying it to rice. It is understood that 30% Aimao EC is a new fungicide introduced by the Swiss Syngenta crop Protection Company, which can not only control rice diseases, but also regulate the growth of rice. The effect of this agent on rice grain

Which points should be paid attention to in the planting of late-planted rice in the whole field with water?
The overall requirement of late-planted rice in equal water field is to grab water and whole field to plant seedlings, increase nests, seedlings and ears. In case of precipitation or other water sources in the paddy fields with water-planted seedlings, measures such as water plugging, water diversion and pumping should be taken immediately to grab water and plant seedlings. Planting density should be increased in late planting fields. If the seedling age is 60 × 70 days, more than 13000 seedlings (8 × 6 inches) are planted in each mu of rice field, and two seedlings (2 grains) are planted in each litter; if the seedling age is more than 70 days, more than 15000 seedlings (8 × 5 inches) are planted in each mu of rice field, and the number of seedlings per mu reaches 150000 seedlings.

Daojie is safe to rice.
Daojie is a sulfonylurea herbicide, which is absorbed by weed leaves, stems and roots and transmitted to the meristem region through xylem and phloem. Daojie is used in rice field, which has the effect of stem and leaf treatment and soil closure treatment. After the treatment of Daojie, the weeds stopped growing quickly, the growth point faded 2-4 days after treatment, and sometimes the leaf veins turned red. 7-14 days after treatment, the stem tips and leaf buds began to wither and necrosis, and the weeds died 2-4 weeks after treatment. The death rate of weeds is related to the accumulation of branched chain amino acids in the body. Young

Harm and Control of Liriomyza huidobrensis in Rice seed production
Rice stalk miner (ChloropsoryzaeMatsumura) is mainly distributed in Heilongjiang, Zhejiang, Jiangxi, Hunan, Hubei, Guangdong, Guangxi, Yunnan, Guizhou, Sichuan, Chongqing and other provinces in China. In recent years, it has become one of the main pests in rice production in hilly and mountainous areas of Chongqing, and the loss caused by it has exceeded that of some important pests such as borer. In rice seed production, the occurrence of Liriomyza huidobrensis seriously affected the development process of rice, which led to poor meeting of parents at this flowering stage and affected seed production.

Current occurrence and Control of Diseases and pests in Rice Seedling Field
Aphids, thrips and blight mainly occur in rice seedling stage, which endanger the growth of rice seedlings. Rice thrips and nymphs are often harmful to the ears, tongues and heart leaves of rice thrips, and yellow and white spots appear in the damaged parts, followed by flower and white spots on the leaves, and the damaged seedlings return slowly to green and shrink, as if they were "sitting". Rhizoctonia solani mostly occurs in wet (semi-arid) seedling fields and dry seedling fields, causing dead seedlings. Due to the unstable temperature in the first and middle of April, it is easy to cause aphids, thrips and blight, affecting the whole seedling, full seedling and strong seedling. Ask the agricultural technology centers of township offices to strengthen water.

Current technical opinions on rice seedbed management
At present, some early sowing areas are affected by the rapid change of temperature of the cold current, rice seedlings have been frozen to varying degrees, which has affected the management of rice field, and will postpone the process of transplanting rice seedlings to a certain extent. In order to do well the seedling field management and reduce the harm of low temperature, the technical suggestions of seedling bed management are put forward. 1. Raising seedlings in small shed. According to the weather forecast, the mulch should be added to the shed, closed and insulated. In case of frost, candles or smoke can be lit in the shed to increase temperature and prevent frost. In raising seedlings in the greenhouse, ventilation should be reduced or even not ventilated, and grass curtains should be surrounded by grass curtains and plastic film should be laid in the shed.

At present, rice mainly attacks diseases in Guangdong.
Rice bacterial streak, rice blast, sheath blight and bacterial blight are four main diseases in late rice production in Guangdong, which mainly damage plant leaves in the early and middle stages of rice growth. There are many typhoon rice areas along the coast of our province, while rice blast and bacterial leaf spot are the main damage in hills and mountainous areas. In this paper, the occurrence period, characteristics and control methods of bacterial leaf spot, rice blast and sheath blight are briefly described as follows: bacterial leaf streak of rice has a tendency to spread in Guangdong in recent years. The disease begins in seedling stage and flourishes in young panicle differentiation stage. Station
