In 1959, more than 40 counties in our district conducted a survey on the yield of early rice. A total of nearly 1,000 fields were surveyed to observe the growth characteristics of the seedlings in the field. Some valuable information and experiences were obtained and some laws were initially found. The information is collated for reference.
