Description

[Detailed description of the invention] The present invention relates to a method for cultivating plants.

Conventionally, when applying concentrated fertilizer, it was applied over a wide distance where plant roots were not distributed, but it was applied in small doses or diluted with water to avoid damaging the roots. Fertilization grooves are created around the four circumferences of the ground under the tree canopy by cutting grooves around the four circumferences of the soil beneath the tree, and filling the ground under the tree canopy with soil (first step).
See figure 0 By applying a concentrated amount of fertilizer, which is originally a nutrient for growing plant roots, stems, and leaves, to this fertilization groove, the roots of the plants below the fertilization groove are Partially kill and prune the roots, whether organic or inorganic.

The concentration and amount of fertilizer is usually such that when applied to a fertilizing groove, the tips of the roots about 10 cm below the area where they come in contact with the fertilizer will wither under rain or irrigation. The concentrated fertilizer applied to the ground surface is
Through percolation, soil moisture is transmitted and penetrates into the ground. If the concentration is high in the upper layer, the roots of the plants will die from the point where they come in contact with the fertilizer.Q Do not apply concentrated fertilizer to the inner plantings of the four pruned circumferences.As a result, the soil under the crown of the tree will be fertilized with nitrogen. enters a state of fasting, and a large number of capillary roots are produced near the ground surface. Here, the term "near the ground surface" refers not only to the vicinity of the ground surface, but also includes the ground surface (see Figures 4 and 5) 0 Pruning and fertilization of the non-fertilized area Applying fertilizer to the ditch,
The contradictory work of root cutting and fertilization can now be done at the same time. Apply concentrated fertilizer to the fertilization groove from time to time as needed.0 Because the capillary roots are essentially under the tree canopy, they can cross the roots of neighboring fruit trees, such as those found in conventional perennial fruit trees, and can be used from a long distance. There is no need to absorb nutrients.

Because the distance from the tip of the root to the main body of the plant is short, combined with the action of capillary roots with strong fertilizing power, the quality of the plant is much higher than the standard by applying concentrated fertilizer in a small groove of about 3/3 of the conventional amount. We were able to harvest a large amount of plants.

The capillary roots under the crown of the tree spread rapidly because there is less direct sunlight.

Do not apply organic matter such as compost inside the fertilization groove.

Even with fully ripened compost, capillary roots will turn into thick roots, and with incompletely ripened compost, the roots will turn brown and burn.

Is the chemical fertilizer concentrated inside the fertilization groove? d~E proof root.

The fertilizer burns and dies. Even if we use herbicides that are said to be particularly harmful to weeds but safe for crops, the capillary roots disappear, and the normal capillary roots 3 (see Figure 3 A) lose many finely branched ciliated roots, resulting in thalidomide disease. Becomes the target 9 (Fig. 8 B)
Reference) 0 Roots disappear or decrease. There is even a case of an 80-year-old mandarin tree with a U-turn in its tap root. When the fruit becomes as shown in Figures 4 and 5, fruits with high sugar content and high vitamin C content can be harvested.

When planting new varieties of fruit trees, etc., use the conventional method (see Figure 6 A)
Do not dig a planting hole such as 0. To prevent the tap root from forming, spread broken rubble or gravel and mound soil on top of it to create a planting joint (see Figure 6B).

While conventional agriculture strives to cultivate roots deeply and increase the soil's strength, the present invention makes efforts to make the roots shallow without plowing and to prevent the soil from gaining soil strength. Shallow roots and capillary roots breathe l],
Absorbs phosphoric acid, which increases sugar content.

The present invention has made it possible for the first time to permanently and densely plant fruit trees using vigorous rootstocks.

The world's fruit tree industry uses cross-tied trees with weak fertilizer absorption capacity due to permanent dense planting, but Japanese rootstocks have poor growth and low productivity. This enabled permanent dense planting with a strong stress script. By cutting the roots and cultivating without adding soil fertility, permanent dense planting using strong rootstocks, which was previously impossible, is now possible.

The fertilization groove may be annular as shown in FIG. 8. It is of course possible to make various changes and modifications to the present invention without departing from the scope of the present invention.
