When is the best time to sow southern soybeans?

In the south, soybeans are usually planted in March and April. Due to the low temperature tolerance of soybean, the best sowing date is when the temperature is stable at 10 degrees Celsius, from beginning of spring to rain.

Pay attention to when planting spring soybeans:

1, seed treatment to improve germination rate. Select seeds with full seeds to dry, so as to improve the growth potential of seeds. Seed dressing with ammonium molybdate or rhizobia when sowing. According to the experiment, the treated seed balls formed earlier and more, grew faster and branched earlier, and the seed setting rate and the number of full pods increased, which could increase production.

2, fine soil preparation, sufficient base fertilizer. Deep ploughing 20 cm, repeatedly raking, turtle back ridge 1 m, dry slope can be wider to prevent water from rotting roots. Potassium phosphate fertilizer is especially needed in the early stage, especially in the three-leaf stage, and soil miscellaneous fertilizer and fireclay ash 1500 kg are required per mu.
