Breeding methods of Robinia pseudoacacia for Greening seedlings

Robinia pseudoacacia is an ideal rare tree species for beautifying and greening urban gardens introduced from abroad in recent years. No matter in greening and watching, afforestation and sand fixation, or improving the ecological environment, it shows great advantages and potential because of its unique characteristics. It will also play a great role in promoting the adjustment of rural industrial structure and increasing farmers' income.

Because Robinia pseudoacacia was introduced into China for a short time, the majority of farmers do not know much about the breeding methods of Robinia pseudoacacia. Based on several years of cultivation experience, the author draws the following conclusions for your reference.

1. Land selection and land preparation: select sandy and black land with high dryness, good drainage and loose texture, which requires irrigation equipment, 667 square meters of farm manure 2m ~ 3 cubic meters, ridging, ridge distance of 50 cm, plant spacing of 40 cm.

2. The treatment of the seed root: cut the seed root to about 8 cm, and the cut should be flat. Soak the cut root segment in ABT No.1 rooting powder 50 mg / kg solution for 2 hours, remove and control dry.

3, the cutting of the seed root: when cutting, look at the soil moisture first, the soil about 3 centimeters below the surface can be clutched by hand, it is better to let go. Dry plots should be watered before cutting.

Put the root section flat in the planed mulch and cover the soil with a thickness of 5mm and 6cm. About 3000 sections of roots are planted with 667 square meters.

4. Management of seedling stage: compaction should be done after planting to keep the soil moist. 1000 times omethoate EC was used to control aphids. Weeding should be shoveled early and small to ensure that the nursery is free of weeds. After weeding, we should go to the ground in time and cultivate more soil as much as possible to prevent lodging in the future.

After the sprouts of Sophora japonica come out, the height of the seedlings is about 30 centimeters, and the first fork should be made at any time.

5, the harvest and storage of the seed root: in the same year, the seed root is not taken in autumn, and the next spring, the seed root is dug up from the ground and sold as soon as possible. if it cannot be sold in time, the seed root must be stored. Keep the moisture of the seed root during storage, at the same time, it should not be too waterlogged, too waterlogged root is easy to rot. After the roots of the seedlings are cut off in spring, if they cannot be planted in time, the seedlings should be pseudo-planted to prevent loss of water.
