Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating a lotus root using a cultivation pot. 2. Description of the Related Art A method disclosed in Japanese Patent Application Laid-Open No. 50-99824 is known as a method for cultivating a lotus root using a cultivation pot. In this conventional method, a culture solution is spread in a pot, small pieces of styrofoam are floated in a layer on the liquid surface of the culture solution, and the stem portion is projected upward from between the small pieces,
The styrofoam layer prevents light from the outside from entering the culture solution. [0003] According to the above-mentioned prior art, there are fewer factors that hinder the growth of crops as compared with the method of cultivating with gravels in pots. However, cultivation using a culture solution tends to result in inferior taste of the crop compared to cultivation using soil. Further, in the conventional method, no consideration is given to temperature control, and even if the styrofoam layer is floated on the culture solution surface to shut off heat, the effect is not sufficient. The inventor of the present invention has long found that the cultivation of lotus roots is greatly affected by the temperature of the soil, and the growth is stagnant when the temperature exceeds 30 ° C. It has been achieved. That is, the method for cultivating the lotus root according to the present invention presupposes cultivation using a cultivation pot made of plastic or the like, and puts a sticky soil for planting seed lotus in the pot, and puts it on the sticky soil. During the entire period from planting to harvest, water was flooded, and the soil temperature was maintained at 15 ° C to 30 ° C for 6 months or more. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a state where a lotus root is cultivated by the method according to the present invention, FIG. 2 is a cross-sectional view of a state where the lotus root is cultivated, FIG. 3 is a plan view of a pot used for cultivation, and FIG. It is a side view of the pot used for cultivation. First, a pot used for carrying out the method of the present invention will be described. Pot 1 is plastic (such as polyethylene)
Or it is made of pottery, etc.
cm, the lateral dimension is about 100 cm, the depth is about 30 cm, a flange portion 2 is provided around the upper surface, and a drain port 3 is provided on the bottom surface.
Is provided. The four corners of the bottom are round (R = 30
-50cm), and even if the root of the lotus grows and hits the four corners, it escapes so that it can be cultivated well. At four corners of the flange portion 2, support mounting holes 4 are provided.
A support 5 is erected in the mounting hole 4, and a windshield and light shielding sheet 6 is mounted on the support 5. This sheet 6
Mainly contributes to cold protection. In addition, sheet 6 (post 5)
It is not necessary to always install it, but install it as needed, such as at the beginning of growth and during a typhoon. The bowl 1 is surrounded by a heat insulating board 7, and a gap is formed between the board 7 and the bowl 1 to allow air to flow. By forming such gaps, the cooling effect can be enhanced. Next, a cultivation method using the pot 1 will be described. First, the clayey soil 8 is put into the pot 1 at a depth of about 20 cm. In the cultivation of lotus roots, the shape deteriorates when gravel or soil mass is mixed. By using viscous soil, the lotus roots can be tasted with four nodes by the earth pressure. [0010] A seed lotus 9 is planted in the above mucous soil 8.
Planting is performed from mid-April to late April. Before this planting, make preparations. Preparation is 60 bark composts per pot
0g, 60g of formic lime kneaded into the soil by late February,
One day before planting (for example, one week before), add 1 organic compound fertilizer.
Apply 20g and add 10 organic compound fertilizers in mid-June after planting.
Apply 0 g. [0011] The period from planting to harvesting is 7 to 8 months, and watering is performed over the entire period. It is preferable that the flooding depth is 9 to 11 cm until the middle of May, and the flooding depth is 5 to 7 cm after the middle of May. Further, in the present invention, in order to avoid the temperature rise of the soil due to direct sunlight, a small piece of styrofoam 1
0 is floating. In the above description, the pot 1 is placed in a sunny place where there is no danger of falling due to strong winds, for example, in a home garden,
Installed on a veranda, in a greenhouse, etc., and maintain the soil temperature at 15 ° C to 30 ° C for 6 months or more. According to the present invention, lotus roots prefer a high temperature in the above-ground part and low temperatures in the underground part. According to the present invention, an ideal environment for cultivating a lotus root in an ordinary household can be created by setting the underground part to 15 to 30 ° C. even if it is 30 ° C. or more in the above-ground part. That is, conventionally, the cultivation area of the lotus root was limited due to the troublesome temperature management, but according to the present invention, such a restriction is eliminated. Specifically, 4-7 kg of lotus root can be harvested per pot, which is equivalent to the annual consumption of a family. In addition, not only the root portion can be used for food, but also the foliage and flowers can be used for ornamental use.
