How to prevent and control the shrinkage of rice seedlings due to zinc deficiency
The shrinking seedlings of phosphorus deficiency generally occurred at the tillering stage after slow seedling, such as slow growth, short plant, slender and erect leaf shape, dark green leaf color, neat top of leaf cluster, significant shortening of leaf occipital distance, redness of some tillering leaf tips and even death of old leaves. The reasons are: first, the soil is lack of available phosphorus; second, the soil temperature and water temperature are low, or the soil contains hydrogen sulfide, ferrous and other reducing harmful substances, which reduce the absorptive capacity of roots; third, excessive application of nitrogen fertilizer, the relative balance of effective nutrients is lost. Control measures according to the effective formation of phosphorus measured by the method of soil testing and fertilization

National Rice experts provide suggestions for drought Relief of Agriculture in Chongqing
Recently, on the basis of organizing discussions by relevant experts in the city, and after consulting and revising the rice expert group of the Ministry of Agriculture, the Chongqing Municipal Agriculture Bureau put forward five technical measures for drought-resistant rice seedlings and transplanting, and specially compiled the "Technical questions and answers on drought-resistant Rice Seedling and transplanting techniques" to help grass-roots agrotechnical personnel and farmers further do a good job in sowing autumn grain to ensure full planting. Affected by the continuation of last year's extreme drought, most rice fields in Chongqing have failed to store water before winter. Since last winter and spring, the temperature has been on the high side, and the precipitation has decreased compared with normal years.

700,000 mu rice in Qing 'an adopted water-saving and high-yield technology of drought cultivation control irrigation in cold region
The water-saving and high-yielding technique of controlled irrigation for dry-cultivated rice in cold region was successfully tested in Qing 'an. This year, the county has 700,000 mu of rice to promote this technology. According to experts 'calculation, about 450 cubic meters of water per mu can be saved, 11.2 yuan of pumping cost can be saved, and the average yield per mu can be increased by 22 kg. In recent years, Qing 'an has reduced the irrigation water consumption per mu from nearly 1,000 cubic meters to 500 cubic meters by carrying out the trinity method of "engineering water saving, mechanism water saving and technology water saving." In 10 years, the paddy field area has grown from 640,000 mu to 1.17 million mu, accounting for half of the cultivated area.

Scientific control of rice stem borer
According to the investigation in various parts of Hubei Province, the mortality rate of Chilo suppressalis over winter this year is higher than that of last year, and the base number after winter is lower than that of last year, but it is still relatively high. In addition, the suitable climate and the expansion of high-quality rice varieties are conducive to the occurrence of rice borers. The first generation of Chilo suppressalis will occur in large numbers in rice areas of Hubei Province, and the control situation is still grim. In view of this grim situation, all localities should strengthen leadership, raise awareness, actively organize prevention and control work, quickly carry out insect mouth grain-grabbing actions, and ensure food production safety. I. Recognize the situation and strengthen organizational leadership. Last winter, our province suffered from freezing ice.

Scientists design rice genes to breed new varieties
Rice has a richer fruity flavor, higher iron and zinc content, and no need to supplement other nutrients, all of which can be achieved through molecular design of rice genes. A few days ago, the author learned from the symposium on "Crop Molecular Design and Innovation" that China is currently building a huge biological information infrastructure platform to ensure that high-quality genes "hit the target". Zhu Yingying, academician of the Chinese Academy of Engineering, said that rice, for example, is preferred for soft and waxy japonica rice, and people also want rice to have a stronger flavor or a special flavor such as "fruity flavor." and

Four passes to control rice sheath blight
In recent years, sheath blight has become the most important disease of rice, and has four major characteristics: first, a wide range of occurrence. Second, there are very few varieties resistant to sheath blight. Third, the harm is becoming more and more serious, even causing lodging through the top. Fourth, the disease is first caused by the lower part of the rice plant, which is easy to ignore and miss the favorable opportunity for prevention and control. It is the key to strictly control the four hurdles in the prevention and control strategy. 1. Salvage sclerotia sheath blight mainly overwinters in rice fields in the form of sclerotia. When overwintering sclerotia pass through winter and spring to early rice transplanting, 60% to 70% of sclerotia can germinate. Most of the sclerotia are lighter than water and longer.
