Embodiment 1

[0024] Embodiment 1 new method for inducing flowering of sweet potato

[0025] The following experiments were carried out in the greenhouse of Yantai Academy of Agricultural Sciences, Shandong Province, China. During the whole test period, the greenhouses were skeleton greenhouses without plastic covering. Except for the short-day treatment, the climatic conditions of the indoor experiment were basically the same as the external climatic conditions.

[0026] This experiment adopts randomized block design, randomly set up 4 treatment areas, and each treatment area has three repetitions. The 4 treatment areas are flat ridge double planting + short day + gibberellin 300mg / L treatment area, flat ridge double planting + short day + gibberellin 400mg / L treatment area, single planting method + short day + Gibberellin 300mg / L treatment area, flat ridge double planting + short day treatment area.

[0027] Divide the greenhouse into 12 plots, each with an area of ​​2m×4m, and distrib...

Abstract

The invention discloses a flowering induction method for sweet potatoes. The flowering induction method for the sweet potatoes comprises the following steps: 1) when the ground temperature is stable at 15 DEG C or higher, sweet potato seedlings are planted in protected land with a flat ridge double-plant planting method; 2) when the sweet potato seedlings turn green and apical leaves stretch, thesweet potato seedlings are subjected to short-day treatment until pollination of the sweet potatoes is finished; 3) when the sweet potato seedlings grow to about 50 cm long, apexes of the sweet potatoseedlings are treated with gibberellin, and flowering induction of the sweet potatoes is completed. With adoption of the method, flowering time of the sweet potatoes can be shortened, and flowering quantity is increased, so that the method is of great significance for increasing the yield of the sweet potatoes.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for inducing flowering of sweet potatoes. Background technique [0002] Sweet potato is a short-day crop. It is difficult to bloom in the north, and nutrients are easily input to the underground, so even if it blooms, it cannot form a large number of seeds. To solve this problem, short sunshine and limiting the expansion of the underground are necessary measures. [0003] Now the sweet potato hybrid breeding in the north mainly adopts artificial darkroom and root grafting to solve this problem. The whole operation process is grafting in early June. Grafting needs to cultivate the rootstock first. After the grafting survives, it is transplanted into a nutrient pot and placed on an iron trolley. It is pushed out of the darkroom in the morning. After short-day treatment, it is pushed into the darkroom in the afternoon. Grafting requires the cultivation of ro...
