There are two main pruning periods of indigo fruit, one is the period of flat stubble cutting, and the other is the period of shaping in the growing season. Flat stubble cutting is their fixed drying time. Through certain pruning, their branches can grow straight and accelerate the germination of branches and buds. In addition, when shaping the shape of fruit trees, it is just at their growth stage. At this time, they also need to be trimmed, which is conducive to them to obtain nutrients conducive to their own growth. 1、 When to prune the indigo fruit? There are two pruning periods, namely, the flat stubble cutting period and the shaping period. In the winter of the second year of seedling survival, flat stubble should be carried out on the plant cluster in order to increase new branches and yield. At the same time, it can also make the branches grow more straight and ensure development. After the fruit trees grow new branches, pruning and shaping should be carried out every 2-3 years. Multiple pruning can remove the overgrown branches, diseased branches, dead branches and densely growing branches, ensure the reasonable structure between plants, so that they will not consume nutrients due to overgrowth, and will not reduce photosynthetic efficiency due to overdense branches. 2、 How to prune the indigo fruit 1. Flat stubble cutting period: when giving the indigo fruit flat stubble, the stubble height should be kept at 5 to 10 cm. If the plant produces more new branches in the second year, in order to prevent the growing branches from being too dense, about six strong branches can be selected and retained, and the remaining branches can be cut off. Each of the remaining branches can grow about 50 fruiting branches.
2. Pruning and shaping period: after flat stubble, prune once a year to cut off dead branches, long growing branches, sick branches and over dense branches, so as to prevent the above branches and leaves from robbing nutrition and hindering plant growth. This will ensure that their production will not decrease. （LanDianGuoShenMeShiHouXiuJian）
