Problems solved by technology

[0003] In the existing actual production, in order to cultivate the seedlings of sweet potato miniature tubers, the miniature tubers are usually directly covered with soil and planted in the land, and the miniature tubers are easily attacked by underground pests; Limited seedling growth due to effects of soil compaction
[0004] In the patent No. ZL2016100671039 "A Method for Stereoscopic Sweet Potato Seedlings", it is proposed to use foam boxes to avoid contact between potato pieces and seedbed soil for continuous cropping, and reduce the probability of potato seedlings being susceptible to diseases. This method has a large workload and is not conducive to improving production efficiency. ; The field soil used needs to be disinfected with pesticides, which is easy to cause pesticide residues, which is not conducive to obtaining high-quality pollution-free sweet potatoes

Embodiment 1

[0039] The present embodiment discloses a method for cultivating sweet potato miniature potato seedlings, comprising the following steps:

[0040] Step 1. The machine opens a planting ditch in the greenhouse of the planting field;

[0041] The width of the planting ditch is 30cm; the depth of the planting ditch is 10cm; the bottom of the planting ditch is flat. The width and depth of the planting ditch are suitable for the discharge of micro-tubers. The flat bottom of the planting ditch is conducive to the laying of non-woven fabrics, the protection of non-woven fabrics, the uniform contact between the substrate and the micro-tubers, and the cultivation, growth and harvesting of micro-tuber seedlings. Pick.

[0042] A seedling-cutting operation path is reserved between two adjacent planting ditches, and the width of the seedling-cutting operation path is 25 cm. It is convenient for manual cutting of seedlings, and it is also convenient for the management of seedlings in the ...

Embodiment 2

[0066] The main difference between this embodiment and embodiment 1 is:

[0067] Step 1, artificially set up planting ditch in the greenhouse of planting field;

[0068] The width of the planting ditch is 20cm; the depth of the planting ditch is 5cm; the width of the operation path for cutting seedlings is 25cm.

[0069] The substrate used in step 4 includes the following substances in parts by weight:

[0070] 3 parts peat soil;

[0071] Vermiculite 0.5 part;

[0072] Perlite 0.5 parts.

[0073] Step six, seedling hardening;

[0074] Preferably, the condition for hardening seedlings in the step 6 is: reduce the substrate temperature to 20° C. 6 days before picking the seedlings. The low temperature resistance performance of the seedlings is effectively improved by hardening the seedlings, which is beneficial to the cultivation of the seedlings.

[0075] Step seven, cut the seedlings.

[0076] The condition of preferably described step seven cutting seedlings is:

[00...

Embodiment 3

[0080] The main difference between this embodiment and embodiment 1 is:

[0081] Step 1, artificially set up planting ditch in the greenhouse of planting field;

[0082] The width of the planting ditch is 25cm; the depth of the planting ditch is 8cm; the width of the operation path for cutting seedlings is 22cm.

[0083] Step six, seedling hardening;

[0084] Preferably, the condition for hardening seedlings in the step 6 is: reduce the substrate temperature to 20° C. 6 days before picking the seedlings. The low temperature resistance performance of the seedlings is effectively improved by hardening the seedlings, which is beneficial to the cultivation of the seedlings.

[0085] Step seven, cut the seedlings.

[0086] The condition of preferably described step seven cutting seedlings is:

[0087] The seedlings grow more than 50cm, and the seedlings are collected in sections of 2 to 3 sections; the seedlings are collected 3 times in the whole seedling stage.

[0088] See t...

Abstract

The invention discloses a method for cultivating miniature sweet potato seedlings. The method comprises the following steps: step one, manually or mechanically furrowing planting ditches in planting fields; step two, covering the insides of the planting ditches with non-woven fabrics, wherein the non-woven fabrics cover the bottom surface and the two side surfaces of each planting ditch; step three, arranging miniature potatoes on the non-woven fabrics in the planting ditches; step four, covering the miniature potatoes placed in the planting ditches by using a sterilized substrate, wherein thesubstrate filling the planting ditches is flush with the ground of the fields; step five, cultivating the seedlings, and controlling the temperature and water of the miniature potatoes, wherein the temperature control conditions are as follows: the temperature of the substrate in the planting ditches is adjusted to be 16-28 DEG C, and the environment temperature of the planting ditches is not more than 35 DEG C; and the water control conditions are as follows: the humidity of the substrate is maintained at 70% to 80%; step six, hardening the seedlings; and step seven, shearing the seedlings;The miniature potatoes are effectively prevented from being damaged by pests and viruses in soil, and the used materials are environment-friendly, and can be directly returned to the fields.

Description

technical field [0001] The invention relates to the technical field of sweet potato cultivation, in particular to a method for cultivating sweet potato microtuber seedlings. Background technique [0002] In the artificially prepared nutrient matrix in the insect-proof greenhouse, small tubers with a diameter of 1 to 10 cm are produced by transplanting virus-free test tube seedlings or cutting stems, called mini tubers. The industrial production of mini-potatoes is a new technology for large-scale and high-standard production of virus-free sweet potato seed potatoes by combining soilless cultivation technology, plant tissue culture technology, aeroponic technology and cutting rapid propagation technology. Due to the small size and weight of the micro-potatoes, which are only a few grams in weight, they are convenient for mass transportation, which solves the problem of difficulty in transportation of sweet potato seeds. Therefore, the production of microtubers has developed ...
