Problems solved by technology

Most of the flood disasters in the Yangtze River Basin occurred from the end of June to around July 20. At this time, conventional japonica rice (the area of ​​conventional japonica rice in the Jiangsu, Zhejiang and Anhui regions of the Yangtze River Basin is about 20 million mu) was in the peak tillering period, causing rice fields in many areas to be flooded and seedlings Severe damage, large yield loss or no harvest

Embodiment 2

[0039]A comparative study of the submergence resistance and plant physiological damage of conventional japonica rice seedlings in the tillering stage under different management measures under the machine-transplanted seedling cultivation method. A field of 8 mu with flat terrain and abundant water sources was selected and divided into 24 plots, each with an area of ​​0.3 mu. It is used to carry out experimental research, and three factors are set in the experiment, factor 1: two treatments of hard land and dry land substrate seedling raising method and conventional nutrient soil seedling raising method; Daejeon was managed with 2 treatments according to the conventional wet management method; factor 3: the field was flooded with water, and the inundation period was 7 days, 10 days, and 15 days respectively. Under different treatment conditions, the ability of rice seedlings to withstand submergence and the changes in the physiological damage of rice plants, find out the mechani...

Embodiment 3

[0041] A comparative study on the submergence resistance and plant physiological damage of conventional japonica rice seedlings in the tillering stage by using different management measures under artificial seedling transplanting cultivation methods. In the project unit, 8 mu of fields with flat terrain and abundant water sources were selected and divided into 24 plots. The area of ​​the plot is 0.3 mu, which is used to carry out experimental research. Three factors are set in the experiment. Factor 1: the seedling field adopts dry management seedling raising method, and the seedling field adopts conventional wet management method. Management method management, after transplanting, the field was managed according to the conventional wet management method for 2 treatments; factor 3: the field was flooded with water, and the inundation period was 7 days, 10 days, and 15 days respectively. 3 treatments, 12 treatments, 2 repetitions, a total of 24 To study the submergence resistanc...

Embodiment 4

[0043] A comparative study of the submergence resistance and plant physiological damage of conventional japonica rice seedlings in the tillering stage under different management measures under the direct seeding cultivation method. In the project unit, a 4-mu field with flat terrain and abundant water sources was selected and divided into 6 plots. The area of ​​each plot is 0.3 mu, used for experimental research, two factors were set in the experiment, factor 1: sowing on June 10, using alternate dry and wet management after live broadcast seedlings, and two treatments of conventional wet management after live broadcast seedlings; Factor 2: The field is flooded with water, and the submergence period is 7 days, 10 days, and 15 days. Three treatments, 6 treatments, and 12 plots were repeated twice to study the submergence resistance of rice seedlings and the physiology of rice plants under different treatments. The law of damage changes, find out the mechanism and method of enhan...

Abstract

The invention discloses a cultivation method of flood-disaster-resistant conventional japonica rice in the Yangtze River basin, and belongs to the technical field of methods for cultivating conventional japonica rice. The method includes the steps of S1, selecting high-quality japonica rice seeds, putting the high-quality japonica rice seeds in a container, adding clear water for soaking, removing the seeds floating above the container, and filtering the soaked seeds. According to the cultivation method of the flood-disaster-resistant conventional japonica rice in the Yangtze River basin, the yield loss rate is reduced to the maximum extent, the flood-disaster-resistant capacity of the planted rice is enhanced, for soaked filed after flood, according to the submerging time, the seedling damage degree, the conditions for submerging the field and the like, a targeted field management technical route after water recession is provided, ideal single yield is obtained, disaster loss is reduced, the content of a disaster-resistant production technology of rice in the Yangtze River Basin in China is enriched, flooding resistance and post-disaster field management operation regulations are improved, and an enterprise standard and popularization integration technology is formed.

Description

technical field [0001] The invention relates to the technical field of cultivation methods of conventional japonica rice, in particular to a cultivation method of conventional japonica rice for flood resistance in the Yangtze River Basin. Background technique [0002] In the past 10 years, the frequency of flood disasters in the Yangtze River Basin has been high, and serious flood disasters have occurred almost every two years. Most of the flood disasters in the Yangtze River Basin occurred from the end of June to around July 20. At this time, conventional japonica rice (the area of ​​conventional japonica rice in the Jiangsu, Zhejiang and Anhui regions of the Yangtze River Basin is about 20 million mu) was in the peak tillering period, causing rice fields in many areas to be flooded and seedlings Severe damage, large yield loss or no harvest. Contents of the invention [0003] The purpose of the present invention is to provide a maximum reduction in yield loss rate, enha...
