A Detailed Explanation of Eight Advanced Rice Transplanting Methods
1. Improved Intensive Cultivation: Transplant young seedlings early at the 3-leaf to 4-leaf 1-heart stage. Fields with good water sources should be transplanted early, while fields with poor water sources can be transplanted slightly later. Both dry-raised and water-raised seedlings are suitable, but basal fertilizer must be applied in full, the soil deeply plowed and leveled, strong seedlings selected as much as possible, and transplanting done in shallow water; both row spacing and hill spacing are 1 chi 3 cun, with three individual plants per hill spaced 3 cun apart in a triangular arrangement. This transplanting method has density within sparseness and sparseness within density, minimizing competition among plants for nutrients and sunlight to the greatest extent, which benefits individual plant development and thus can greatly increase yield. It is the most advocated transplanting method today. Two
