Winter cut mulberry, can make mulberry more than the next year, to lay a good foundation for raising silkworms. The specific method is: mulberry should be carried out before and after the "winter solstice" 10 days. There are three types of pruning methods:
1. Leave the main branch of winter trees at a height of 80 centimeters or so. Cut off the branches and young shoots (the strong branches can stay high, and the young shoots stay short). Selected as a long stay tree tail, have better soil and fertilizer conditions.
If we raise the silkworm species in the next spring, we need to keep large tree tails when cutting in winter. However, if you engage in mulberry growing in winter, do not leave large tree tails in winter. It is best to leave in the middle. To the mulberry tree with a large tree-tail, in the spring, there will be more sprouting, more shoots and more flowers and flowers. It is imperative to pick the mulberry flower in time and request winter fertilizer.
2. In the middle and low cutting styles, cut the upper branches 40 to 60 centimeters from the ground; cut the upper branches 30-40 centimeters from the ground. The low, middle cut mulberry germinated later, but the branches were thicker and more robust. It is better to keep low and medium cuts for mulberry fields that are cultivated in winter.
3. Root cutting type In the winter, the branches on the ground are cut off. The pruning is formed, which is conducive to picking silkworms in the spring of the following year, and harvesting mulberry in the second half of the year. When the roots were cut, all those who had originally cultivated earth in Sangtou should dig the cultivated soil first, and then cut off some of the branches on the ground. Mulberry in the Sangtang District. When pruning, care should be taken not to mask it by mud.
4. Matters needing attention Regardless of which pruning method should be adopted, care should be taken to ensure that the incision is slippery and slightly inclined. Do not cut through the mulberry branches and xylem and avoid cutting with a knife. Second, cutting branches should be carried out on a cloudy day so that the loss of sap is less and wounds heal faster. After cutting branches, it is necessary to reapply winter fertilizer. Once again, the cortex and shoots of the new shoots are often over-debrised as a result of mulberry mulching, mulberry and mulberry shoots harvested through the year. Low-, mid-cut, and root cuts are possible when large tree-tails are left. Http://
