Embodiment 1

[0017] 1) Build a seedling pond: On April 23, 2007, in the experimental plastic greenhouse of Yunnan Agricultural University, after the ground was leveled with a hoe, a pool with a depth of 20 cm, a width of 100 cm, and a length of 150 cm was built with bricks. Put it on the plastic film pad, and then fill the pool with water.

[0018] 2) Floating seedling trays are loaded with medium: on the same day, use 2 foam plastic trays as seedling trays. The specifications of each seedling tray are 70cm long, 35cm wide, and 5cm high. There is an inverted pyramid-shaped seedling raising hole with small holes at the bottom, and the hole spacing is 0.5cm. Each seedling-raising hole is all filled with the culture medium that the perlite and humus soil soaked in advance are mixed, and the ratio of the two is about 1:10 by weight.

[0019] 3) Sowing virus-free test-tube mini-tubers: on the same day, sow the germinated Atlantic virus-free test-tube tubers with an average tuber weight of 0.2-...

Embodiment 2

[0026] 1) Build the nursery pond: build the nursery pond at the same time, place and method as step 1) of embodiment 1, the pond is deep 15cm, wide 100cm, long 140cm.

[0027] 2) Packing culture medium in the floating seedling-raising tray: the same method as step 2) of embodiment 1, using the same seedling-raising tray to pack the same medium. The medium is prepared by mixing perlite and humus in a weight ratio of 1:8.

[0028] 3) Sowing virus-free test tube micro-tubers: On April 23, 2007, the Atlantic virus-free test tube tubers with germinated average tuber weight less than 0.2g were sowed in the seedling holes with medium on the seedling tray, and the sowing depth was about 1cm . Sow 1 microtuber in each seedling hole.

[0029] 4) Put the sown seedling trays in the pool for floating cultivation.

[0030] 5) During the cultivation period, no water was used, no pests and diseases were found, and no pesticides were applied. On May 7, 2007, 14 days after sowing, the germi...

Embodiment 3

[0035] 1) Build the nursery pond: on April 25, 2007, at the same place in step 1 of embodiment 1, build the nursery pond with the method, the pond is deep 30cm, wide 150cm, long 200cm.

[0036] 2) Packing culture medium in the floating seedling-raising tray: the same method as step 2) of embodiment 1, using the same seedling-raising tray to pack the same medium.

[0037] 3) Sowing virus-free test-tube micro-tubers: On April 25, 2007, the virus-free test-tube tubers of the germinated average tuber weight 0.2-0.5g were sown in the seedling holes with medium on the seedling tray. About 2cm. Sow 1 microtuber in each seedling hole.

[0038] 4) Put the sown seedling trays in the pool for floating cultivation.

[0039] 5) During the cultivation period, no water was used, no pests and diseases were found, and no pesticides were applied. On May 4, 2007, 9 days after sowing, the germination of the microtubers in the virus-free test tube was observed. On May 22, 27 days after sowing,...

Abstract

A potato floating seedling growing method with detoxification tube; the steps comprises that a seedling pond is built; the floating seedling disc is filled with culture medium; the miniature potatoes in detoxification tubes are sown in the seedling holes of the culture medium filled on the seedling disc; the seedling disc is put in the pond for floating cultivation for 25 to 40 days after the seedlings are sown and then the young seedlings are picked out and transplanted with culture medium on the roots. The present invention of a floating seedling growing technology promotes the miniature potatoes in detoxification tubes to germinate fast and tidily and cultures robust seedlings; in this way, the potato production cost is reduced; the germination rate is high and the potato loss of robust seedlings in tubes is little; the germination rate can reach more than 95 percent; the germination rate in nutrition pot is much lower with the same conditions; the potatoes are easy to be transplanted alive; the root system of the robust seedlings grows well and the root system will not be damaged in transplantation with culture medium because the culture medium is loose; therefore, the potatoes are easier to survive compared with the potatoes cultured with present method; the facilities are simple and can be repeatedly used; the operation is convenient.

Description

technical field [0001] The invention relates to the technique of growing seedlings of potato virus-free test-tube microtubers, in particular to a method for raising seedlings of potato virus-free test-tube tubers by floating. Background technique [0002] The popularization and application of virus-free test tube microtubers is the fundamental way to solve the degradation of potato species and promote the rapid and healthy development of potato production. Chinese patent publication number is CN1582624, publication number is CN1326670, publication number is CN1188593, publication number is CN1048141, publication number is CN1083076 and publication number is that many inventions such as CN1631088 disclose multiple detoxification test tube miniature tuber production methods, the miniature tuber production method The production technology is relatively mature. At present, the method usually adopted for the propagation of the original seed of microtubers in test tubes is to bro...
