Manihot esculenta crantz rapid propagation method based on atomization nutrient solutions

Abstract

The invention discloses a manihot esculenta crantz rapid propagation method based on atomization nutrient solutions. The manihot esculenta crantz rapid propagation method comprises the steps that 1, one ends of 20-30 cm manihot esculenta crantz seed stems are place into cultivating pots at first, the other ends of the manihot esculenta crantz seed stems extend out of planting holes of a box body cover plate, 2-3 bud eyes are reserved outside the other ends of the manihot esculenta crantz seed stems, the planting holes are sealed, the nutrient solutions with the 1/2 concentration are added into the cultivating pots, and atomization cultivating is conducted for 30-35 days through an atomization device; 2, after the root systems of the manihot esculenta crantz seed stems touch the cultivating pots, lifting brackets are removed, the cultivating pots are directly placed on bearing platforms, the manihot esculenta crantz seed stems above the box body cover plate are fixed through a fixing device, and cultivating is continued with nutrient solutions with the normal concentration; and 3, after cultivating is conducted for 85-90 days, the manihot esculenta crantz seed stems located above the box body cover plate are cut into several segments, the step 1 to the step 3 are continuously repeated or cultivating is continued for 15-20 days, then the manihot esculenta crantz seed stems are transplanted to the field to be planted, and the temperature in a cultivating box body is controlled to be 20 DEG C-28 DEG C. The manihot esculenta crantz rapid propagation method based on the atomization nutrient solutions has the advantages that propagation can be conducted at any time, and the propagation rate and the survival rate are high.

Description

technical field [0001] The invention relates to the technical field of plant artificial cultivation, in particular to a rapid propagation method based on nutrient solution atomization. Background technique [0002] Cassava (Manihot esculenta Crantz), also known as sweet potato and cassava, belongs to the Euphorbiaceae (Euphorbiaceae) cassava (Manihot) shrubs. There are more than 100 species in the genus. Cassava is the only species suitable for economic cultivation, and the others are wild species. Its roots and leaves are edible. Mainly grown in tropical and subtropical regions. [0003] Cassava is a kind of asexually propagated crop. Generally speaking, reproduction is relatively easy. Traditionally, mature lignified seed stems in cassava planting are used as seed stems in the second year, and the annual propagation speed is 10 to 15 times. Because the original breeding technology of cassava cannot meet the production needs of new varieties. The supply of improved seeds...
