At present, the city’s rice growth has gradually entered the jointing long ear stage. According to the investigation of the seedling situation on July 27, the average leaf age of machine-planting rice is 11.86 leaves, which is 1.04 leaves less than that of the same period of last year; the average leaf age of orchard-planting rice is 13.1 leaves, which is more than last year. At the same time, there were more 0.12 leaves; the average leaf age of direct-seeded rice was 10.68 leaves, which was 0.24 leaves less than the same period last year. The total number of larvae inserted 299.6 thousand seedlings of rice, 59,700 seedlings less than the same period of last year; Thrive rice seedlings 354,000 seedlings, a year-on-year decrease of 53,500 seedlings; Direct seed rice was 452,500, a decrease of 38,900 seedlings year-on-year. This year, the overall number of rice seedlings in the peak season is lower than normal, and the population is suitable. This will be beneficial to the field management in the middle and late period and the shaping of high light efficiency groups, laying the foundation for raising the spike rate and winning large spikes and high yields. Although this year's large-scale rice production is generally better, there are still some outstanding problems in the local plots: First, the number of partial crops in the field is high, especially when some plots are not timely landfilled, and a large amount of high-leafed tillers are generated after the field is reclaimed. Potentially, the difficulty of applying fertilizer at a later stage increases, and it is easy to cause premature failure and reduce the production risk of spikelets. Second, some plots use more partial tiller fertilizer, and some field blocks are long and thick and apply joint fertilizer to apply urea. The current growth is more prosperous and the leaves are darker. , Adding the previous cropland to the field is not in place. Potentially, there are potential hidden risks in the later period; Third, some plot groups are insufficient and individual growth is insufficient. Especially, a considerable part of late seeding, late seedling emergence, and severely droughty live rice fields with fertility, fertility The process was significantly postponed, potentially threatening to severely reduce production. Therefore, all localities must focus on “mainly attacking large spikes, preventing premature senescence, preventing lodging, and preventing pests and diseasesâ€, and pay close attention to the field management of rice in the middle and later stages, and focus on the application of rice panicle fertilizer, promote the formation of large spikes, and achieve high yield and quality of rice.
1, due to the guidance of seedlings classification, the application of panicle fat attack big spike. At present, rice begins to enter the stage of reproductive growth, and it requires large amounts of fertilizer at the later stage. Heavy panicle fertilizer is the key to seizing high yields. In view of the current weather conditions and field seedlings, combined with the time of fertilization until rice has absorbed, in order to ensure that the fertilizer efficiency in the differentiation of branch stems to the spikelet differentiation stage promotes the formation of large spikes, this year's rice panicle fertilizer application should be due to , due to the way of planting, requiring a one-time application to promote flower fertilizer, Miao Qiao to see the flower fertilizer. Specific application time and amount of fertilization: machine insert rice and throw-thrown rice at the end of July - August 5, acres of urea 10-12.5 kg plus efficient compound fertilizer 10-15 kg; other Daikou direct seed rice application time in August 8- On the 12th, urea urea 7.5-10 kg plus 12.5-15 kg of high-efficiency compound fertilizer; Ningjing 3 varieties of panicle fertilizer applied properly postponed 1-2 days, no later than August 15 applied to promote flowering fertilizer. From August 15 to August 18, throwing rice and inserting rice to see if the seedlings were properly used for flowering fertilizers, the fertilizer application amount was 4-5 kg ​​of urea or 10-12.5 kg of high-efficiency compound fertilizer. Principle of application of panicle fertilizer: throwing rice, machine inserted rice to see the seedlings promote good, ensure two panicle fertilizer, direct broadcast rice field to promote flower fertility, conservation of fertilizer does not advocate the application. At the same time, the early application of leaf color is light, and the color of leaves is appropriately delayed. The use of a large group of fields will reduce the dosage appropriately, and if the population is insufficient, the dosage will be increased appropriately.
2, scientific management of water slurry, enhance root vitality. The upper root and panicle differentiation of rice occur synchronously, and the upper root is the main functional root system in the late growth stage of rice. Increasing root activity is an important physiological basis for rice high yield. Lands that are not in place will continue to implement soft-laying, light-racking, and dewatering to put aside the fields. They will put the fields away at the end of July and early August. In the booting stage and heading and flowering stage, shallow water layers should be established, and the rest of the stages should be mainly dry and wet alternately to ensure hard water in the field, to maintain the roots and leaves, to increase the vitality of the root system, and to prolong the life span of the roots, so as to adjust the fertilizer with water and raise the roots by gas. Improve the effect of grain weight. Before the harvest, about 10 horses were irrigated to prevent premature dehydration at a later stage, affecting rice quality and yield.
3, do a good job spraying fertilizer, prevention and treatment of premature aging. Spraying foliar fertilizer at late stage of rice growth can optimize the canopy structure of rice, promote photosynthesis, increase photosynthetic efficiency, prolong the lifespan of upper functional leaf, effectively prevent late premature failure, and achieve significant yield increase. In particular, the proportion of floods and direct seedings this year is relatively large, and the early stage of stiff seedlings has been delayed. Some fields are currently deprived of power and yellow lean. All localities must combine the prevention and pest control to vigorously publicize the root-spraying fertilizers, which are used once in the booting, breaking and full heading stages of rice. Each time, 50-100 grams of foliar per acre sprays on the water, raises the roots to protect the leaves, reduces the degradation, increases the firmness, and increases the grain weight.
4, comprehensive control of pests and ensure safe production. During the middle and late stage of rice production, the major pests and diseases are endangered. In accordance with the forecast and forecast of the plant protection department, localities should pay close attention to the occurrence of diseases and insect pests at the ear stage and focus on the overall pest prevention and control. In the near future, we must focus on the prevention and control of rice planthoppers, rice leaf roller plants, and sheath blight. In accordance with the unified formula, we must implement unified defense rules and comprehensively control the pests and diseases.
5. Based on disaster reduction and disaster reduction, harvesting bumper crops. In the middle and late stages of rice production, natural disasters such as typhoon, rainstorm, and hail are frequent, and local governments must base themselves on disaster prevention and multi-hit disasters to prepare for disaster prevention and disaster prevention as soon as possible so as to prevent problems. We must pay close attention to meteorological changes, keep abreast of local and regional disasters, and do preventive work in advance. In field management, farmers are instructed to open a set of trenches inside and outside the field to ensure smooth drainage and irrigation. As early as possible, formulate technical measures for stress resilience to ensure that the disaster can be restored in time after the disaster and reduce the losses due to the disaster. At the same time, all localities should combine rice high-yield activities to create a high-yield management model, establish a high-yield model, and enhance the model's radiation capabilities. It is necessary to earnestly conduct investigations and researches on different rice cropping methods and compare the yield and benefits of direct-seeded rice and machine-transplant rice seedlings, so as to lay a solid foundation for the further transformation of rice cultivation methods and improvement of the comprehensive rice production capacity.
