Tortoiseshell planting techniques

1, selection of the land

Tortoiseshell flowers like a warm and humid environment, cold tolerance is weak, seedlings are afraid of frost, cultivation of soil to deep, well-drained sandy loam is appropriate, should not be planted in saline alkaline soil. After selecting the land, ploughing 2-3 times, removing weeds, breaking up the soil, and then according to the fertility status of the soil into the rotted organic fertilizer as a base fertilizer, mix it with the soil and make the bed, waiting for planting.

2, reproduction methods

Tortoiseshell flowers can be produced by seed, cuttings, grafting three methods of reproduction, but seed propagation of seedlings are prone to mutation, so they are rarely used in the production, or as rootstocks. Cuttings are propagated in April-May by selecting well-grown, robust branches from a pest-free mother plant as scions, which are cut into 15-20 cm lengths. Remove the lower leaves of the spike, inserted diagonally in the sand bed, keep the seedbed moist, at the right temperature, usually in January can be rooted. Grafting reproduction in the production of the use of more, can be used branching or leaning method, grafting after the survival of cultivation 1-2 years can be transplanted.

3, field management

Tortoiseshell flower has the characteristics of multiple tresses, need to consume a lot of nutrients, so we should be fertilized many times, fertilizer to Zephyr water-soluble fertilizer-based, appropriate application of some quick-acting fertilizer. In April, when the plant began to twig, each twig should be fertilized, in the winter to chase the overwintering fertilizer, and cake fertilizer, stable fertilizer-based, open furrow ring. In the drought should be timely, but in the summer to pay attention to, should not be watered too much resulting in stagnant water, winter plants in a dormant state, to control the watering.

4, pests and diseases

Tortoiseshell's main disease is leaf spot disease, the onset of the disease from the edge of the leaf, the first brown spots, spots spread, irregular shape, and finally appear black granules and rot. For this disease to strengthen field management, maintain good ventilation and light penetration, the onset of the spraying of the antimicrobial control, every ten days and a half months spraying, 2-3 times in a row to control the disease. Pests are blowing sheep mediator, generally in high temperature and high humidity and poor ventilation environment is easy to occur, its excreta will also produce soot disease, for this disease can be sprayed with Rogaine control.
