A Complete Analysis of the Key Points of Large Flat Apricot Cultivation and Management
1. Planting method Before planting, soak the seedling roots in water for 24 hours, take them out and dip them in a water-retaining agent, then plant them. After planting, irrigate thoroughly, and once the water has seeped down, cut the trunk back to a height of 80-100 cm. With the main trunk as the center of the planting hole, cover with 1 m x 1 m plastic film, press the edges of the film down firmly with soil, and leave the area around the planting pit slightly higher. Years of practice have proven that covering with plastic film after planting both retains water and raises soil temperature, causing the tree to sprout early and grow quickly. One week after planting, slip a plastic bag over the trunk, with a bag length of 40 cm and a width of 10 cm. To prevent
