Detailed Explanation of Key Management Techniques for Apricot Trees in Greenhouses
1. Fertilizer and water management. After covering with plastic film, no more fertilizer is applied as a top dressing. After fruit set and during the pit-hardening stage, spray once with 0.3% urea plus 0.2% photosynthetic micro-fertilizer and 0.3% potassium dihydrogen phosphate. Install drip irrigation pipes inside the greenhouse and water reasonably according to soil moisture. Do not water excessively, to avoid excessive vigorous growth of new shoots, which can cause physiological fruit drop. 2. Training and pruning. For "Y"-shaped training, mainly retain lateral branches, appropriately thin out or utilize upward-growing branches, leave mediocre branches unpruned, cut back drooping branches, and remove overly dense branches, diseased and pest-infested branches, and dead branches. 3.
