Management of planting mango before planting

1. Calibration

Calibrating and digging holes: the orchard first two ploughs and two rakes, deep 30cm deep turning and ripening. The orchard on the hillside is planted according to the contour, first from top to bottom, a vertical baseline is determined, and the planting points of the two rows of high planting rows in the middle of the hillside and at the foot of the mountain are determined according to the plant distance. Then the planting points of other contour planting lines are determined by forming a line at two o'clock. The flat orchard takes the main road and slip road as the benchmark according to the specified plant spacing, and each planting line is parallel or perpendicular to the road. The size of the planting hole is 80 × 70 × 60cm, which is dug 2-3 months before planting.

2. Application of base fertilizer

Organic fertilizer (cow manure, pig manure, etc.) 20kg, phosphate fertilizer (calcium superphosphate or calcium magnesium phosphate) 1kg were applied in each hole, fertilizer and topsoil were mixed in the middle and bottom layer, and the surface soil was 15-20cm higher than the ground. Base fertilizer should be applied one month before planting.

3. Planting technology

Planting before rain or cloudy days, such as planting in the afternoon on sunny days, dig a small hole in the planting hole, put the seedling with soil mass in the hole, tear the plastic bag from the bottom and roll it up to remove the soil mass. When filling the soil, step from the outside of the soil mass, the planting depth is slightly higher than the soil surface, repair the annular ridge after planting, and drench the roots with water, and then sprinkle water every 2-3 days until survival.
