Abstract

The invention relates to the field of pineapple tissue culture, and discloses a hardening-seedling and temporary planting method for a Tainong No.16 pineapple tissue culture seedling. The method comprises the following steps: (1) rooting culture of a tissue culture seedling; (2) hardening-seedling; (3) preparation before transplanting; (4) transplanting; (5) management at transplanting time; (6) field planting. According to the hardening-seedling and temporary planting method for the Tainong No.16 pineapple tissue culture seedling provided by the invention, the transplantation survival rate of the pineapple tissue culture seedling can reach over 95%; the pineapple tissue culture seedling can quickly restore to growth after being transplanted; compared with other transplanting methods, the seedling time can be shortened by about 20 days; compared with a traditional seedling method, the seedling cost is lowered by over 20%; the plant grows and develops regularly evenly in the whole growth period; field management is facilitated; the fruits are good in economic characters, and have significant economic benefits and social benefits.

Description

technical field [0001] The invention relates to a method for hardening and false planting of Tainong No. 16 pineapple tissue cultured seedlings, and belongs to the technical field of pineapple tissue culture. Background technique [0002] Pineapple is one of the "Three Tropical Herbal Fruit Trees" in the world and one of the "Four Famous Lingnan Fruits" in my country. It is deeply loved by consumers because of its rich nutrition, sweet taste, and unique flavor. By 2011, the production area and output of pineapple in my country (excluding Taiwan Province) were 57,300 hectares and 1,519,100 tons, respectively, ranking among the top ten in the world. In the hot areas of our country, pineapple has always been one of the important sources of income for fruit farmers, and has extremely high economic and social importance. There are many varieties of pineapples, among which Tainong No. 16 is an excellent fresh pineapple variety bred by the Chiayi Agricultural Experiment in Taiwan....
