Description

  The present invention relates to a leaf surface water supply method for fertilizing and supplying water to the leaf surface of a plant.

  In general, when the root's nourishing water absorption function is reduced, or even when the root is healthy, the transpiration from the leaves is intense, so it is necessary to perform foliar nutrient water when absorption from the root is insufficient. is there.

  2. Description of the Related Art Conventionally, in soil cultivation, hydroponics, and the like, a method of spraying nourishing water with a sprayer has been widely performed as a method for performing foliar application water on plants with the stems facing upward.

  However, the conventional method has a drawback that it takes time and effort to replenish the entire leaf stem part without worries, and in actual spraying, the water droplets remaining on the leaf surface act as a convex lens that collects sunlight. This creates burns on the foliage, impairing the value of the product.Furthermore, in curly crops such as lettuce and cabbage, moisture penetrates deep into the curly leaves, and in celery and the like, water droplets remain at the base of the petiole. However, when such moisture soaks into the plant and becomes hot and humid, diseases such as Kinkaku disease, gray mold disease, and Nampu disease have occurred.

  The invention of the present application can be applied to the entire leaf stem portion without trouble, and after the work, the leaf surface of the plant is able to prevent disease by almost no moisture remaining in the leaf stem portion. It is an object to provide a recharge water method.

As means for solving the above problems, the present invention
In the inverted state with the leaf stem part down and the root facing up, the plant is immersed in nourishing water to perform leaf surface nourishing water,
Then, in the inverted state, the plant is drained by pulling upward from the nutrient water.
A method for foliar water treatment of plants is proposed.

  According to the leaf surface water supply method of the present invention, when the plant is inverted and the leaf stem part is immersed in the nutrient water, the entire leaf stem part can be applied with nourishing moisture, and after immersion, the plant is When it is pulled up from the nutrient water in the inverted state, it can be drained automatically by draining the nutrient water adhering to the leaf stem part coupled with the vibration during the work, and thereby, Kinkaku disease, gray mold disease, Nampu disease It can prevent diseases such as, and does not burn the leaves.

(A), (b), (c) It is each approximate line sectional drawing which shows the process of the foliar water supply method of this invention. (A), (b), (c) It is each schematic sectional drawing which shows another Example process.

  In the “draining” in the present invention, in addition to the vibration at the time of work, it is desirable to add a promoting action such as giving light vibration to the inverted plant or blowing air to the leaf stem.

This example is an example in which foliar water is applied to a plant planted in a cultivation box.
As shown in FIG. 1, the cultivation box (1) is provided with a root storage chamber (2) in a box made of a heat insulating material, and a plurality of planting holes opened from the top surface of the box to the root storage chamber (2). (3) is provided, and the stems (4) of the plant planted in the planting hole (3) are placed on the upper surface of the box (1), and the root (5) is placed in the root storage chamber (2). A culture solution injection tube (6) for extending the culture solution from the outside into the root storage chamber (2) and a culture solution discharge tube (7) for discharging the culture solution from the root storage chamber (2) to the outside. It is equipped with. (8) and (8) are U-shaped handles protruding from the left and right outer surfaces of the cultivation box (1).

  A large number of cultivation boxes (1) planted with the above plants are adjacent to each other on the two guide rails (9) and (9) made of mountain-shaped materials as shown in FIG. In this state, the culture solution is injected from the culture solution injection tube (6) into the root storage chamber (2) from the outside, and from the culture solution discharge tube (7) to the root storage chamber (2). ) Cultivate by draining the culture medium inside.

  At the beginning of planting seedlings, the nutrient water absorption from the roots is not sufficient, so if it is judged that foliar nutrient water is required, each cultivation box (1) ... is guided to the guide rails (9), (9) It is made to run up and is moved to the top surface open box type leaf surface water tank (10) containing the culture solution (11) as shown in FIG. The leaf stem portion (4)... Is immersed in the culture solution (11) and the foliar surface water is applied while the stem portion is inverted. By the above immersion, the entire leaf stem portion can be brought into contact with the culture solution without any wrinkles and effective nutrient absorption can be performed.

  After the required time of foliar treatment water, the cultivation box (1) is lifted upward as shown in FIG. 6 (c), and the leaf stem (4) is lifted from the culture solution (11). Then, the handle (8), (8) of each cultivation box (1) ... is detachably locked to the hanger (12), (12) and is held in the raised state. The nutrient water adhering to each leaf stem part (4) ... flows down by the vibration at the time of work, and drains. In addition, the vaporization of water is useful for cooling the leaf stem part, especially in summer.

  Here, the small vibrators (13) and (13) attached to the above-mentioned hanging tools (12) and (12) are started, and the vibrations are transmitted to the leaf stems (4) through the handles (8) and (8). Communicate, thereby further promoting the draining.

  After completion of draining, each cultivation box (1) is returned to the normal posture and moved to the cultivation position shown in FIG.

  As another example, the cultivation box (1) is supported on the two guide rails (9) and (9), the culture solution is injected from the injection tube (6), and from the discharge tube (7). Cultivation while discharging to the outside is carried out on the foliage tank (10) in Fig. 1 (b), and if necessary, the cultivation box (1) ... is inverted as shown in Fig. Draining may be performed after the recharge water.

In this example, foliar water is applied to a plant planted on a panel.
The panel (1a) is provided with a plurality of planting holes (3a) in a rectangular plate such as a synthetic resin foam and wood, and the leaf stems (4a) of the plant planted in the planting holes (3a) are arranged. On the panel (1a), the roots (5a) are respectively extended below the panel (1a), and a large number of the plant-planting panels (1a) are placed in a box with an upper surface containing the culture solution (11a). Cultivation is carried out by supporting the mold cultivation / foliar application water tank (10a) near the liquid surface and immersing the root (5a) in the culture liquid (11a).

  If the plants that are cultivated as shown in Fig. 2 (a) are transpiration from the leaves in summer, etc., and foliar water is needed, plant planting as shown in Fig. 2 (b) The installation panel (1a) is inverted, and the leaf stems (4a) that are turned downward are immersed in the culture solution (11a) to perform leaf surface water treatment.

  Here, in order to prevent drying of the roots (5a) ..., the culture solution (11a) of the cultivation tank (10a) is sent to the water spray pipe (15a) by the pump (14a), and from each water spray nozzle of the water spray pipe (15a). You may make it water each root (5a) ....

  After performing the foliage treatment water for the required time, the panel (1a) is lifted upward while being in the inverted state, the leaf stem (4a) is lifted from the culture solution (11a), and in this state, the handle (8a) , (8a) is detachably locked to the suspenders (12a) and (12a), held in the pulled-up state, and drained in conjunction with vibration during operation. At the same time, the leaves and stems are cooled by water vaporization.

  Furthermore, in this example, the blowers (16a) and (16a) send wind to the leaf stems (4a)... To promote the vaporization of the moisture, and further promote the draining action by shaking and drying by the wind pressure.

  After draining, each panel (1a)... Is returned to the normal posture and moved to the original cultivation.
