Cultivation method for improving quality of Rosa roxburghii Tratt

Abstract

The invention belongs to the technical field of planting, and specifically discloses a cultivation method for improving the quality of Rosa roxburghii Tratt. The specific steps are as follows: (1) preparing a seedling raising substrate: a seedling raising substrate is self-made and laid flat in a planting greenhouse, the seedling raising substrate is piled up to be 30cm thick and laid flat on thesoil in the greenhouse, furrowing is carried out to obtain furrows with width of 2-2.2 meters, and ditches of 0.5-0.8 meters are dug between the furrows; (2) planting; (3) inter-planting; (4) field management; and (5) fruit harvesting. The method has the advantages as follows: the survival rate of Rosa roxburghii Tratt seedlings can be improved, and the survival rate of seedlings after transplanting is high because of high adaptability of the seedlings; and the quality of Rosa roxburghii Tratt is guaranteed, and the yield of Rosa roxburghii Tratt is also improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of planting, and in particular relates to a cultivation method for improving the quality of Rosa roxburghii. 【Background technique】 [0002] Prickly pear (Rosa roxburghii Tratt) is a perennial plant belonging to the genus Rosa of the family Rosaceae. The fruit has extremely high nutritional, health care and medicinal values. It is a new fruit tree unique to my country and is being vigorously developed. It is commercially cultivated in more than 10 provinces (regions) including Guizhou, Sichuan, Yunnan, Guangxi, Fujian, and Henan. At present, the cultivated area in Guizhou Province alone has reached more than 500,000 mu, and it has become a key development characteristic industry in the whole province. More than 50% of the fruits produced are used for juicing. Only Guizhou Province produces more than 40,000 tons of fruit residue after juicing every year. And increase year by year, almost all throw away at ...

At present, the cultivated area in Guizhou Province alone has reached more than 500,000 mu, and it has become a key development characteristic industry in the whole province. More than 50% of the fruits produced are used for juicing. Only Guizhou Province produces more than 40,000 tons of fruit residue after juicing every year. And increasing year by year, almost all of them are discarded at present, which not only causes great waste, but also pollutes the environment

[0003] Rosa roxburghii is mainly planted in mountainous areas. The success rate of seedling cultivation of Rosa roxburghii is not high, and the quality of Rosa roxburghii seedlings is not high, resulting in a low survival rate after transplanting. In order to increase fruit production, a large number of pesticides are used to eliminate insects, which seriously affects the The quality of thorn pears; and traditional farmyard manure or quick-acting chemical fertilizers are generally used for fertilization of thorn pears. Usually, the number of fertilizations is 3-4 times a year. The type and amount of chemical fertilizers are usually based on experience, or the nutrients cannot meet the needs of the tree, resulting in yield. and quality decline, or serious pests and diseases due to excessive forms of a certain type of element; at the same time, due to the serious loss of quick-acting fertilizers, the utilization rate of fertilizers is low and environmental pollution is caused
