Pay close attention to the Prevention and Control of Diseases and pests in Middle and late Rice to ensure the Safety of Rice production
At present, the middle rice is in the heading and setting stage, and the late rice is in the tillering to jointing stage, which is the critical period for the occurrence, development and damage of diseases and insect pests. In order to effectively control the major diseases and insect pests of rice and strengthen the prevention and control measures, the National Agricultural Technology extension Service of the Ministry of Agriculture was launched on August 20.

When will early, middle and late rice be planted respectively? When is the best time to harvest?
Rice is the most important and oldest kind of grain. Originally from China, rice was grown in the Yangtze River Basin in China 7,000 years ago. Due to the different climatic environment, rice in China can be divided into three categories: early, middle and late rice, so when will they be planted respectively? When will it be collected?

Nearly 80% of the seedling raising of early rice has been steadily expanded.
Since late February, South China and Jiangnan have successively entered the period of raising seedlings and planting early rice from south to north. According to the agricultural situation regulation of the Ministry of Agriculture, it is estimated that the intended planting area of early rice this year is more than 87 million mu, an increase of more than 300,000 mu over the previous year. Recently, the Ministry of Agriculture is concerned about the production of early rice.

Pay attention to three precautions of rice after flood
From mid-late June to mid-late July, the southern region is often hit by torrential rain, and some areas are prone to floods. In case of flood and waterlogging disasters, in addition to carrying out routine remedial measures, attention should be paid to the prevention of the epidemic of bacterial diseases and the outbreak of migratory pests. Prevent the epidemic of bacterial brown stripe disease. With the flooding, the bacteria were able to spread and spread and infect through the wounds caused by Rain Water and rice plants during the flood. The resistance of flooded rice plants decreased, which was more conducive to the epidemic of the disease. There is a process from the flood to the epidemic of the disease, therefore, for the medium rice in the flood area,

Management measures for jointing and long panicle stage of Rice
At present, the growth of rice in the city has gradually entered the stage of jointing and panicle growth, which is not only an important period for the transformation from vegetative growth to reproductive growth, but also a key period to determine yield. To do a good job in the field management of rice in the middle and later stage is very important for protecting full panicle, attacking large panicle, shaping high-yield plant type and setting up high-yield shelf. 1. Seedling characteristics according to the survey on July 21, the average leaf age of mechanically implanted rice was 12.31, 0.49 more than that of the same period last year, the average leaf age of direct seeding rice was 10.31, 0.56 more than that of last year, and the total number of tillers was 38.63.

Eight measures for safe use of Rice
1. Reasonable selection of varieties. Rice blast is the main disease affecting harvest, and the difference of resistance among different varieties is very obvious. The selection of varieties with strong resistance is one of the most effective prevention measures. In the old rice blast area and the cold soaking field in the shade, first, the resistance of the varieties should be carefully understood when selecting and purchasing seeds; second, the new varieties can only be planted in a small amount before being popularized; third, imported Fuji No. 1 should be used for prevention in the early stage of the disease and the stage of booting and heading. Where the humidity is high in the mountain area, it is not suitable for late hybrid rice to choose and purchase two-line hybrid late rice combinations to prevent rice false smut.
