Cultivation method for increasing survival rate of camellias

Abstract

The invention provides a cultivation method for increasing survival rate of camellias. The cultivation method is characterized by including collecting normally growing stumps without serious surface bark injury, wherein root systems flourish, the age of trees is 5-20 years and the ground diameter is 5-8 centimeters; selecting loam for planting, and selecting one-year green branches which are positioned on the upper-middle portions of variety crowns, have plump leaf buds, and are free of pest and disease damage and uniform in thickness; performing cut-grafting, side-grafting or bark-grafting; after buds of newly-planted stumps grow to 10-20cm and leaves darken, applying a dilute rich water solution once every 10 days, and applying 60 parts of nitrogenous fertilizer from the first ten-day period of March to the beginning of April; from the middle ten days of May to the beginning of June, applying 50 parts of phosphate fertilizer, 20 parts of potash fertilizer and 10 parts of farmyard manure; not applying fertilizer from June to the middle ten days of September, applying 40 parts of phosphate fertilizer and 15 parts of potash fertilizer from the last ten-day period of September to the first ten-day period of October, and applying 20 parts of phosphate fertilizer and 7 parts of farmyard manure in November; keeping the temperature at 10-25 DEG C. By the cultivation method, the survival rate of the camellias is increased, flowering phase of the camellias is lengthened, and ornamental quality of the camellias is improved.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method for improving the survival rate of camellias. Background technique [0002] Camellia is an evergreen shrub or tree with a long life span, strong adaptability, and a long history of cultivation. It likes warm, humid, and semi-shady environments. It is afraid of high temperatures and avoids the scorching sun. Humid air environment, avoid drying, it is a semi-yin plant, suitable for growing under scattered light, afraid of direct light exposure, high temperature and dry summer and autumn, the ornamental quality of camellia will be greatly affected, the seedlings of camellia need shade, but Long-term shading is unfavorable for the growth of camellia, and the survival rate of camellia is low. In the prior art, the operation is complicated and consumes a lot of energy. Contents of the invention [0003] The purpose of the present invention is to improve the survival rate ...
