Description

Technical Field

[0001] The invention belongs to the technical field of cassava sprout cultivation, and in particular relates to a cultivation method of cassava sprout vegetables. Background Art

[0002] With the improvement of people's living standards and the change of eating habits, green food is generally loved by people. People are not only satisfied with the quantity of vegetable supply, but also pay more attention to the quality indicators such as the appearance, quality and edible safety of vegetables. Sprouts are loved by consumers as nutritious, high-quality, pollution-free health green food. Therefore, sprouts have become a new type of vegetable industry with great development prospects. At present, the more popular sprouts on the market include more than 30 varieties such as toon sprouts, buckwheat sprouts, alfalfa sprouts, acacia bean sprouts, radish sprouts, peanut sprouts and broad bean sprouts. But there is no relevant report on cassava sprouts.

[0003] Cassava is a tropical crop, and its tuber is rich in starch and is an important food source in many regions. Usually after cassava is harvested, if there is no plan to expand production, 90% of the seed stems will be discarded. In fact, a single bud eye of the seed stem can sprout many times, and using the seed stem to produce sprouts is a way to efficiently utilize cassava by-products. Cassava sprouts are nutritious vegetables grown from cassava seed stems. They have the common characteristics of sprouts, such as rich nutrients, unique flavor, crisp taste, and certain health-care effects. Therefore, it is of great significance to provide a method for cultivating cassava sprouts.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The invention aims to provide a method for cultivating cassava sprouts, which can provide an excellent growth environment for the cultivation of cassava sprouts and is conducive to mass production of high-quality cassava sprouts.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A method for cultivating cassava sprouts comprises the following steps:

[0008] S1. Spray potassium permanganate solution on the surface of the planting frame to disinfect it, and evenly spread coconut bran in the planting frame;

[0009] S2. Select the middle and lower sections of healthy cassava stem cuttings that are 30 cm long. Soak them in clean water for 30 minutes, then soak them in a disinfectant solution for 30 minutes for disinfection, and then take them out and let them dry naturally. Among them, the distance between the bud eyes of the cassava stem cuttings should not exceed 2 cm. Otherwise, if there are too few bud eyes, it will affect the yield of the bud seedlings.

[0010] S3. Insert the cassava cuttings obliquely and relatively on both sides to the bottom of the coconut coir in the planting frame body, leaving no gaps between the stem cuttings. According to the principle of preventing the collision of bud eyes, after planting, the average occupied position for each plant is 5 cm, and 16 plants are planted in 80 cm.

[0011] Water thoroughly.

[0012] S4. Transfer the planting frame body to a ventilated indoor environment, avoid light, and maintain the indoor temperature at 26 - 28.8 °C; Apply water to maintain the relative humidity around the bud eyes of the cassava at 70 - 90%; (During the experiment, use an electronic temperature and humidity recorder to remotely monitor the temperature and humidity around the bud eyes. When the humidity is lower than 70%, apply water in a timely manner;

[0013] S5. Harvest when the cassava bud seedlings grow to 10 - 20 cm.

[0014] Preferably, in step S1, the thickness of the coconut coir laid in the planting frame body is 8 cm.

[0015] Preferably, the planting frame body is composed of three layers of unit frame bodies. The unit frame body is a hollow structure with an open top, and its bottom plate is evenly provided with water-permeable and air-permeable holes; A support foot is also fixed at the bottom of the unit frame body.

[0016] Preferably, the unit frame body is 80 cm long, 40 cm wide, and 22 cm high.

[0017] Preferably, the interval between the upper and lower two layers of the unit frame bodies is 25 cm.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By setting the planting frame body, laying coconut coir in the planting frame body, inserting the cassava obliquely and relatively to the bottom of the coconut coir during planting, and maintaining the relative humidity and temperature around the bud eyes of the cassava during the planting process, the present invention can provide an excellent growth environment for the cultivation of cassava bud seedlings, which is beneficial to the mass production of high-quality cassava bud seedlings.
