Sweet potato stem tip cultivation method

Abstract

The invention discloses a sweet potato stem tip cultivation method which comprises the steps of: shearing rattan sections or potato seedlings of fresh sweet potatoes, and carrying out close planting according to the requirements that planting distance is more than 5cm and less than 10cm, and the line spacing is more than 5cm and less than 10cm; inserting the rattan sections or the potato seedlings into a rectangular substrate cultivation box with the width of 20-80cm and depth of 10-20cm; after that, putting the culture box onto a multilayer three-dimensional cultivation frame, and carrying out sweet potato stem tip facility cultivation management; when the temperature in a shed exceeds 38 DEG C in a sunny day, covering a sunshade net on the roof of the shed to reduce the transpiration; when the temperature in the shed is lower than 25 DEG C, heating and carrying out heat preservation to increase the temperature in the shed to 25-38 DEG C, and maintaining the humidity in the shed to be more than 90%; when new stem tips grow out by 8-12cm, harvesting the sweet potato stem tips. The method adopts moderate close planting and three-dimensional facility cultivation, thus remarkably improving the yield of the stem tips. The method is convenient in mechanical harvest, improves the harvest efficiency, realizes large-scale production and can be used for sweet potato stem tip cultivation and breeding throughout the year.

Description

technical field [0001] The invention relates to a method for cultivating sweet potato shoot tips. Background technique [0002] At present, the large-scale production of sweet potato stem tip cultivation methods is limited to field cultivation, and ridge cultivation is carried out in the usual way, and some increase the cultivation density to 5000-8000 plants / mu (667m 2 ). However, this has unreasonable parts for the cultivation method for the purpose of cultivating shoot tips. Firstly, the cultivation density is too low and the land utilization rate is low, which affects the yield of shoot tips; secondly, the ridges cause height difference, which is inconvenient for mechanical shoot tip harvesting, and manual harvesting is costly and inefficient. It is the biggest bottleneck of large-scale production; thirdly, field production is limited by seasons and affected by climate change, so it cannot carry out year-round production and cannot provide market annual demand.
