Key Points of Post-Grafting Management Techniques for Top-Grafting and Variety Conversion of Citrus
1. Do well in cutting the rootstock stubs. After using side grafting with exposed buds, the rootstock stubs should be cut or sawed off. This should be done in two steps. First, leave about 15cm of rootstock stub above the graft union. After the new shoots have become lignified, cut the stub flush with the graft union and smooth the cut surface with a knife. 2. Do well in removing sprouts. After top-grafting, because the apical dominance has been removed,

Citrus November Management Experience and Key Points
I. Strengthen management for improving late-stage citrus fruit quality ① Focus on reducing soil water-holding capacity before harvest. Moderate drying of the soil before harvest helps reduce the effectiveness of nitrogen fertilizer, can concentrate the juice, increase sugar content and maintain relatively high acidity, giving the fruit a richer flavor. In autumn

Control Methods for Mango Fruit-piercing Moth Pests and Diseases
I. Damage. The more serious pests include the fruit-piercing moth (Oraesia emarginata), the bird-beak fruit-piercing moth, the dead-leaf fruit-piercing moth, and the super-bridge fruit-piercing moth. The adult moths use their sharp mouthparts to pierce into the fruit and suck the juice of the flesh, causing the fruit to drop. Fruit pierced before harvest will rot during storage and transport. II. Morphological characteristics.

What management work needs to be done before planting mangoes in the field?
1. Marking out Marking out and digging holes: The orchard is first plowed twice and harrowed twice, with deep turning and ripening to a depth of 30cm. For orchards on hillsides, planting is done along the contour. First, from top to bottom, establish a vertical baseline, and according to the baseline and the plant spacing, mark out the planting points for two contour planting rows at the middle and foot of the hillside to the left and right. Then, using two points to form a line, mark out the planting points for the other contour planting rows. For flatland orchards, use the main road and branch roads as baselines and mark points according to the specified plant and row spacing, with each planting row parallel or perpendicular to the roads. The planting hole size is 80×70×60cm, and holes should be dug 2-3 months before planting.

What issues need attention when growing licorice?
1. Seed treatment. Before sowing, treat the seeds with water at 60-100°C for 30 seconds; then soak them in warm water for 1 day and night, and the germination rate can reach 50%. If treated with concentrated sulfuric acid, remove the seeds immediately once the seed coat turns black and rinse them in clean water, then soak them in warm water, and sow when the seeds swell; the germination rate can reach more than 90%.

Summary of Field Management Experience in Balloon Flower Cultivation
1. Thinning and final thinning: When seedlings are 3-5 cm tall, carry out thinning 1-2 times; when seedlings are 10-12 cm tall, carry out final thinning at a spacing of 6-8 cm. 2. Cultivation and weeding: During the seedling stage, weed and loosen the soil frequently; when the seedlings are small, it is best to pull weeds by hand, and each thinning should preferably be combined with weeding.
