II. Raising methods for poplar seeds

1. Selection of the raising site

The raising site should be chosen as a plot that is fertile, moist and well drained, and at the same time it must be ensured that the plot has the feature of being convenient for irrigation and drainage, so as to ensure that water can be applied and drained at any time.

2. Land preparation and fertilization

Before cuttings, the land must be fully prepared, with a plowing depth of more than 25 cm, achieving deep and fine preparation. If a rotary tiller is used, it is best to firm the soil after plowing. When deep plowing, apply fertilizer as a base fertilizer at 20 kg of urea, 75 kg of superphosphate, 10 kg of potassium sulfate and other fertilizers per mu, and at the same time apply 1-2 kg of carbofuran per mu to kill underground pests.

3. Collection and treatment of planting stems

For poplar cutting propagation, one should collect 1-year-old seedling stems 2-2.5 m tall that are well lignified, free from disease and insect damage, with a straight and full trunk form, and with plump lateral buds, as cutting stems; generally the middle and lower parts are of the best quality. The time for collecting stems is generally before spring sprouting, cutting as one collects, but stems may also be collected in late autumn after the seedlings shed their leaves; storage through the winter can promote the formation of callus tissue at the cut, which is beneficial for rooting of the cuttings.

4. Cutting time and method

In general, cutting in early spring is preferable. The cuttings are inserted straight into the seedling bed, and when cutting, the cuttings must absolutely not be reversed. In addition, cuttings from the base, middle and top of the planting stems should be inserted separately. This can make the seedlings grow uniformly and avoid the phenomenon of the large bullying the small. After cutting, water must be applied immediately so that the cuttings and soil are tightly combined.

5. Timely topdressing

Topdressing generally uses about 50 kg of urea per mu per year, and at the same time a certain amount of phosphate fertilizer and potassium fertilizer can be added according to the soil conditions. Topdressing is generally carried out in three applications in late May, mid-June and mid-July.
