How to Apply Topdressing to Lettuce: Detailed Explanation of Application Techniques
Lettuce is topdressed a total of 3 times throughout its whole growth period. The first topdressing is carried out 15 days after seedling establishment, applying 12 kg of urea per 667 sq m (1 mu) to promote seedling tillering and sturdy growth; the second topdressing is carried out at the early head-forming stage. The third topdressing is carried out at the mid head-forming stage to promote full and swollen heads. Each time per 667 sq m (...

Detailed Explanation of Key Management Techniques for Plum Trees During the Flowering and Fruiting Period
Management of plums during the flowering and fruiting period: Plum trees flower easily and have a high fruit-setting rate, but the fruit is small. To improve fruit quality, in addition to strengthening soil and fertilizer management and adopting summer pruning to control vegetative growth, flower and fruit thinning management should be carried out. Thin flowers during the flower bud swelling stage (late March), leaving one flower cluster branch and removing the next; at 20 to 30 days after flowering...

Efficient management techniques for peach trees to help achieve high yields
Peach tree rot, also known as dieback disease, causes branches to wither and die after the tree is affected, forming canker lesions on large branches and the trunk. If not treated in time, it quickly causes the entire tree to die. The main causes of this disease are: frost damage and extensive management; improper fertilization and years with abundant autumn rain, which delay the peach tree's dormancy and reduce the tree's cold resistance. It has...
