南华浩淞大豆气象分析报告：巴西产区进入营养生长阶段，阿根廷关注降雨情况

1. Report Industry Investment Rating - No relevant content found 2. Core Viewpoints of the Report - The overall soybean planting in Brazil and Argentina is progressing well, but attention should be paid to the rainfall in Argentina in the next two weeks [1][2][15][39] 3. Summary by Related Catalogs 3.1 Brazil's Meteorological Situation - Brazil's national soybean sowing progress has reached 97.6%, and the crops are generally in good growth, gradually recovering from the negative impact of uneven rainfall in December [1][15] - In the central region, it has entered the vegetative growth stage, and the replanted areas in the east and south are at the historical average level [1][15] - In Mato Grosso and Mato Grosso do Sul, continuous rainfall is conducive to most areas entering the reproductive growth stage and showing good yield potential [1][15] - In Goiás, the planting work is nearing completion, the rainfall has returned to normal, and the problems of soil moisture shortage and uneven growth have been alleviated [1][15] - In Minas Gerais, sowing is basically completed, but excessive rainfall in some areas has delayed the fertilization progress [1][16] - In Paraná, about one - third of the area has entered the grain - filling stage, and most crops are growing well [1][16] - In Rio Grande do Sul, effective precipitation has alleviated the previous soil moisture shortage and created favorable conditions for the germination of areas sown in early December [1][16] 3.2 Argentina's Meteorological Situation - Argentina's sowing progress has increased by 8.2% week - on - week to 75.5%, with a good rate of 99% and a water sufficiency rate of 96% [2][39] - The first - sown soybeans have entered the late growth stage, and the planting in the northern Pampas agricultural area continues. Recent significant rainfall in the northeast is beneficial for soil moisture recovery [2][39] - About 10% of the planted area has entered the vegetative growth stage, mainly in the central and southern regions, with sufficient soil moisture [2][39] - The second - season soybean planting has completed 57.9%, and the central and southern regions are progressing well. However, there may be a decrease in rainfall in the next two weeks, so rainfall needs to be continuously monitored [2][39] 3.3 International Soybean Annual Focus Points - January: U.S. soybean exports, South American production, global soybean ending stocks, and Chinese imports [57] - February: U.S. exports, Chinese imports, Chinese stocks, and (planting intention forecast) [57] - March: Brazilian exports, South American production, and U.S. sown area [57] - April: South American production, U.S. sown area, and Brazilian exports [57] - May: U.S. and Chinese sown areas, and Brazilian exports [57] - June: U.S. yield per unit area and Brazilian exports [57] - July - September: U.S. yield per unit area [57] - October: U.S. yield per unit area, production, and South American planting area [57] - November - December: U.S. production, South American planting area, and U.S. exports [57] 3.4 Soybean Growth Cycle and Weather Requirements - Planting period: The average daily temperature of the 5 - cm soil layer at the beginning of sowing should reach 10 - 12°C. After germination, the suitable temperature for seedling growth is 15 - 25°C, and the moisture should be maintained at 60% - 70%. Disaster risks include floods and extreme drought [65] - Blooming period: The suitable temperature is 20 - 28°C, and the soil water content should be 70% - 80%. Disaster risks include floods, droughts, etc. [65] - Growth period: The suitable temperature is 21 - 23°C, and the soil field water - holding capacity should be about 70%. Disaster risks include heatwaves, droughts, and pests [65] - Harvest period: The suitable temperature is 15 - 25°C, the air relative humidity should be 50% - 60%, and the soil moisture should be about 40% - 50% of the field water - holding capacity. Disaster risks include continuous rainfall and storms [65]
