According to Mr. Oanh, the time of rapid rice laying is an important time that can decide the yield of the whole crop because rice yield is formed based on the following factors: number of panicles (number of effective branches)/unit of area. ; number of firm seeds per cotton; grain weight. Of the above factors, the number of effective branches is the most important factor. So to have the highest number of effective branches, people need to understand the growth characteristics of rice, the nutritional needs of each period and most importantly, choose the right type of fertilizer for rice.
People need to increase the application of care measures according to the growth stage of rice. At this time, rice plants need to add potassium supplements, spray more foliar growth promoters for plants to grow, develop healthily, and improve resistance to pests and diseases. Rice plants need to have enough water to soak their feet for better tillering and at the same time limit harmful rats…
