Southern Rice Production Situation This Year and Market Trend Outlook
According to monitoring by meteorological departments, rice growth and development are good, but with the excessive rainfall and the continuous migration of pest sources from abroad, the pest and disease situation in southern production areas is severe, forming a certain adverse impact on rice yield and quality in the later period. At the same time, driven by the sharp rise in prices of agricultural products such as edible oil and pork, combined with a partial recovery in rice demand, domestic rice prices have recently shown an overall trend of steady increases. The specific situation is briefly analyzed as follows: 1. This year's new rice production situation in the south 1. Favorable factors support
