Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cultivating rice and wheat.

Traditionally, in rice cultivation, seedlings are grown by sowing them in seedling boxes, but due to the large amount of seeds being sown, germination is uneven.
When rice is transplanted, the seedlings grow unevenly in size, the ears are not aligned, and there are few paddy grains.Also, plowing the field, puddling, and rice transplanting require mechanical power, which increases machine costs for tractors and rice transplanters, and fuel costs. In the paddy field after rice transplantation, most of the wheat stocks and weeds remain in the soil and generate organic acids, which impairs the growth of rice roots. Because barley stocks and weeds block direct sunlight, it is easy to prevent the seedlings from taking root and growing after rice transplanting, and even though mechanical power is used, there is no significant difference in profits compared to the era of animal-powered agriculture, and in terms of balance sheet. This can easily lead to losses. In addition, when growing wheat as a secondary crop, mechanical power is required after field plowing, planting rows, drainage ditches, sowing soil, and treading, making the cost relatively high. Additional fertilization and fertilization require labor, which impedes the growth of plowed rice plants, which leads to uneven tillering, many late ears, and little grain set, which leads to the loss of the appropriate harvest period, which tends to reduce the taste and quality of the wheat, etc. There were some shortcomings.

In order to solve the above-mentioned drawbacks, the present invention aims to sow wheat and rice without plowing the field, to use undivided cultivation in wheat cultivation, and to cover soil in a triangular shape between wheat plants in rice cultivation, so that germination occurs. It is a direct-seeding, non-dividing cultivation method in which grown seedlings are irrigated to a depth of about 3 cm using irrigation ditches to grow only the parent ears.This method minimizes mechanization and fertilization while maintaining the health of rice and wheat. It is characterized by the ability to grow parent ears and appropriately manage sunlight, air, water, temperature, and fertilizers to reduce production costs, improve quality, and increase yield.

Hereinafter, the structure of the present invention will be explained with reference to the drawings showing examples of the present invention.

A large number of irrigation and drainage ditches 1 are planted at appropriate intervals on the left and right sides without tilling the field, and 4 to 6 rows of planting ditches for sowing are planted at mutual intervals between the irrigation and drainage ditches 1. Six grains of wheat are placed in the grooves, each with hexagonal symmetry, and 36 grains constitute one wheat plant and two grains each.
The distance between the front and back of the plants is about 10 cm, and each plant is sown diagonally in a triangular shape in the left and right cultivation grooves, and covered with soil. After germination, the fertilizer is suppressed and no pressure is applied. Wheat is harvested by growing parent ears without dividing, and then, in rice stocks, each row of wheat plants (3, 3') on the left and right, parallel to the irrigation ditch 1, is used as a cultivation row for sowing. A groove is made, and in the groove, about 5 grains of rice are arranged in hexagonal symmetry, and about 30 grains make up 1 rice plant (4), and the distance between the front and back of each plant is set.
In addition, sow one plant each in a triangular shape diagonally opposite each other in the left and right cultivation grooves and cover with soil, and after germination, add water to each rice plant row 5 and 5' from irrigation and drainage ditch 1 at a depth of about 3 cm. By irrigating the rice to increase direct sunlight, water temperature, and soil temperature, and improving air circulation, rice can be harvested by growing parent ears without dividing while suppressing fertilizer use, and harvesting wheat and rice alternately. It is something that should be done as much as possible.

Next, the effects of the present invention will be explained with reference to practical example diagrams.

The present invention is for cultivating rice as a top crop and wheat as a sub-crop without direct sowing in the field. First, in cultivating wheat as a sub-crop, the wheat grains sown without tillage are exposed to sunlight by the rice plants after harvesting. By transmitting the direct heat of the sun into the ground, the soil temperature rises and promotes the growth of root hairs. Also, since there is no plowing between the wheat plants, the soil does not freeze deep even in winter, and the amount of fertilizer is reduced and the leaves are not divided. It has strong stems and is not easily damaged by frost. Then, a small amount of additional fertilizer is applied before the ears form, and during the ripening stage, the rice plants are sold and used as organic fertilizer to promote ripening.Since the cultivation is done without dividing only the parent ears, mechanical power is required. It requires less fertilizer, reduces production costs, and yields high-quality wheat.

In addition, rice cultivation is a no-till, direct-seeding type, and irrigation ditches 1 are used to irrigate shallow water to a depth of about 3 cm, raising water and soil temperatures through direct sunlight, and in addition, increasing the absorption rate of fertilizers. The decomposition of the wheat stump roots is also promoted and healthy parent ears are grown. And because the rice plants are located diagonally opposite each other on the left and right sides,
It has direct sunlight and good air circulation, and because only the parent ears grow, it is resistant to pests and diseases.All ears mature at once, and there is no immature rice, resulting in good-tasting, high-quality rice. It is something that can be done. Moreover, since it is not directly seeded, it has the remarkable effects mentioned above, such as significant savings in machinery costs, fuel costs, labor costs, etc., lowering production costs, and making it possible to increase sales. .

Claims (1)

[Claims] 1. Without tilling the field, a large number of irrigation and drainage ditches 1 are planted at appropriate intervals on the left and right sides, and any number of planting ditches for sowing are planted at the intervals of each irrigation and drainage ditch 1, and the cultivation Place wheat grains in the row furrows at appropriate distances from front to back so that one plant consists of dozens of grains, and sow and cover the wheat grains with soil so that each plant in the left and right cultivation trenches faces diagonally in a triangular shape.
After germination, the main fertilizer is suppressed, and the parent ears are grown without treading and dividing, and the wheat is harvested.Next, in rice cultivation, each wheat plant row 3 is placed in one set on the left and right parallel to the irrigation and drainage ditch 1. , 3', create a cultivation groove for sowing, and leave appropriate intervals in the front and back so that several tens of paddy grains constitute one plant in the cultivation groove, as well as the right and left cultivation grooves.
