High temperature dominates the weather in the south, and rice paddy management pays attention to the timing of scientific water use.

Since June this year, the number of hot days in Changsha, Nanchang, Fuzhou, Chongqing and Hangzhou has exceeded or nearly 20 days. According to the forecast of the Central Meteorological Observatory, in the next three or four days, the weather stage in the south will still be the main character of the high temperature, but the maximum temperature will generally not climb to more than 40 degrees. Although the hot weather in South China will converge slightly, this is only temporary, and the maximum temperature will climb to over 35 degrees in the next few days. High temperature is unfavorable for the heading of rice in the Yangtze River Basin. It is easy to cause the increase of open space. At the same time, the temperature in the central and southern parts of the south and south and south of the south of the Yangtze River is high and the precipitation is less. The possibility of drought is greater, which is not conducive to the growth of late rice and tillering. Linyi Fertilizer Network Copyright

Jianghuai, Jianghan, most of Chongqing, eastern Guizhou, and eastern Sichuan Basin should pay attention to deep water to reduce panicle temperature and prevent high temperature from affecting earing; Jiangnan and South China should avoid late transplanting of late rice at high temperature and strengthen post-transplantation of late rice. Field management, pay attention to water temperature regulation, prevent high temperature hazards, improve the survival rate of seedlings to return to green; and pay attention to the scientific plan to use water to prevent the adverse effects of possible drought on crop growth and development.

For the remedial measures after the rice suffers from “high temperature heat damage”, the following methods are introduced for your reference: Linyi Fertilizer Network Co., Ltd.

(1) Strengthen the late stage management and reduce the damage caused by the disaster. It is necessary to strengthen the field management in the later stage for the fields that are generally affected but not harvested. Through effective field management, the empty granules can be significantly reduced, and the grain weight can be increased to obtain a better harvest. Linyi Fertilizer Network Copyright

1. Adhere to shallow water and humid irrigation, and implement live water irrigation for the heavily affected fields (that is, shallow irrigation with long flowing water, and the effect of cooling is more obvious), so as to prevent the drought from being further aggravated by the autumn drought, because the high temperature and heat damage are often intertwined with drought. together. In the later stage, it is advisable to cut off the water too early, and it is better to cut off the water 7 to 10 days before harvesting, which not only can increase the yield but also ensure the quality of the rice.

2. Strengthen the prevention and control of pests and diseases. In particular, the control of rice leaf roller, rice planthopper and bacterial blight, rice smut, and sheath blight. Linyi Fertilizer Network Copyright

3. For the light disaster field that is damaged by heat during the booting stage, it should also be supplemented with grain fertilizer before and after the break period. It can be used for 2~3 kg of urea, and it can also be applied with phosphorus and potassium fertilizer and plant growth regulator to increase the seed setting rate and grain weight.

4, timely harvest, fine-grained. Linyi Fertilizer Network Copyright

(2) Retaining the reclaimed rice and recovering the loss of production. According to the different levels of disasters in different regions, it is an effective post-disaster remedy to store reclaimed rice according to local conditions. Should be mastered. Through field investigations, the seed setting rate is below 10%, and it is expected that the harvested land with a yield of less than 100 kg can be remedied by means of reclaiming rice. For the affected fields that accumulate regenerated rice, the heads of the open stalks can be cut off after the disaster, and the germination-promoting fertilizer (7.5-10 kg per mu) should be applied in time to strengthen the field water and fertilizer management and pest control. The germination of the regenerated shoots, followed by the heading and grouting, is generally able to obtain a yield of 200-250 kg per mu, which is equivalent to recovering more than 50% of the output.
