Repair of Overplanted Citrus Trees by Staggered Ditching
In the newly-built orchard, due to various reasons such as the sinking of new soil, citrus roots and necks are buried from time to time. In production practice, the author summed up the method of alternate drainage to remedy, and the effect was good. 1in the winter of 993, the author used this method to treat 60 mu of super-planted satsuma mandarin orange orchard, so that all mating nodes were exposed, the ditches in the orchard were connected, and the root growth environment was greatly improved. This method is simple and practical, saves labor and time, and is especially suitable for orchards with high groundwater level.
The specific method is: dig a ditch every two rows of trees. The cross section of the ditch is inverted trapezoidal or V-shaped, and the slope direction of the ditch is subject to the fact that the joints can be completely exposed. The bottom of the ditch is generally lower than the joint 10 ~ 20cm, and the ridge surface is higher than the original plane 10 ~ 20cm.
After the implementation of this method, we should pay attention to two aspects: first, the soil layer on the side of ditching is shallow and barren, and the root system is shallow, so we should pay attention to enriching the soil and maintaining the root system; Second, because of the high ridge formed by the accumulation of soil in the ditch on the vehicle surface, the root system on the other side is deeply distributed, so this side is not suitable for fertilization in the current year. Chinese Citrus 1994 No.3 was originally published.
