Growth habit of citron tree
The citron tree prefers warm and humid climate, afraid of severe frost, and not hardy. It is suitable to be cultivated on sandy soil that is deep, loose and fertile, humus-rich and well-drained. The citron tree is suitable for a hot and humid environment and apparently originated in the southern region. There are semi-wild citron trees in the broad-leaved forests of Xishuangbanna, Yunnan.
Citron tree propagation methods
1. Seed propagation: citron tree seed propagation is generally selected in October to mature fruits, the seeds are cut and taken out, washed and dried and then sown, or stored in wet sand, sown in the spring. Open a furrow, row spacing 30cm, evenly sown, mulch, watering, cultivate 2-3 years.
2. Cuttings propagation: Selected 2~3 years old branch cuttings of hua tangerine red, remove the thorns, cut into small sections of about 18 cm, cuttings in the spring high temperature and high humidity season. Row spacing 30cm, plant spacing 12cm ditch, oblique insertion, mulching, will be cuttings compact watering, exposed 1/3 of the ground. Cultivate and plant for 1-2 years.
Cultivation techniques for citron trees
1. Field management: tilling, weeding and fertilizing citron trees 2-3 times a year, from May to September with human and animal manure as the main, but also with dilute liquid cake fertilizer. It is feasible to increase the application of calcium superphosphate in winter. Prune overgrown branches and overcrowded branches. The result is the insertion of a pole.
2. Reasonable fertilization: the first fertilization of the citron tree is before the buds, and the second fertilization is after the summer solstice. The second application of fertilizer can also be mixed with 250 grams of urea and 500 grams of calcium superphosphate, add water 100 times. Sprayers are used to apply fertilizer outside the roots to promote vigorous plant growth of the fruit.
3. Pest control: Citron tree diseases include sooty mold, which damages leaves, branches and fruits. There is also the blowing cotton mesquite, which can be controlled with the natural enemy, the ladybug beetle. Turpentine mixture can also be sprayed, diluted 8 to 10 times in winter and 20 times in summer. There are also aspens, red spiders and aphids.
