Detailed Explanation of Key Cultivation Techniques for Spring Maize and Late Rice
1. Deep planting of milk-stage seedlings, dry management to promote root growth and preserve seedlings. The techniques of raising seedlings in fertilizer balls and soft trays must be implemented, and the technique of deep planting of milk-stage seedlings must be carried out well. According to research, transplanting milk-stage seedlings has the advantages of early vigor and strong seedlings, strong dry matter accumulation capacity, sturdy plants, well-developed root systems, large and numerous ears with heavy grains, and low empty-stalk rate; its early-maturing and high-yielding growth advantage is 6 days earlier than production cultivation, and the seedling recovery period...
