Among the mechanization of wet rice cultivation, the one that has lagged behind the most is the planting process. Now, the principle of raising seedlings on the box surface used in today's rice transplanters is my invention, as described below. Numerous rice transplanters were researched in order to improve the complicated work involved in hand-planted rice cultivation that had continued since the Meiji era. Until around 1950, all of these rice transplanters ended in failure. When we investigate the reasons for these failures, we find that
The mistake was to adopt a method in which seedlings grown in a nursery were run through a rice transplanter. Therefore, I made a major change in my thinking and realized the need for a method of raising seedlings that was easy to use in a rice transplanter, and focused on this point. At the same time, I was researching the minimum limit and had confirmed that the minimum amount of soil required to grow one seedling was 1 cubic centimeter. If this limit is applied directly to seedling raising, Honda 10a
Seedlings i11 needed for! , 000 shares (according to the calculation at the time, 60 tsubo
The amount of seedlings (300 tsubo per plant) can be grown in an area of only 2 square meters. 1 will be possible. If this is the case,
It was concluded that a box surface that is easy to machine is possible. Therefore, I devised a bento box-shaped nursery for cutting pictures and a honeycomb-shaped seedling nursery for potted seedlings, and spent several years negotiating with 2 to 5 companies to produce prototypes of these nursery machines. In the end, Mitsubishi Plastics' Nagahama factory had to deal with the problem. Because the Nagahama factory was unable to manufacture the honeycomb-shaped seedling nursery, a prototype was produced a few years later at the Mitsubishi-affiliated Monsando factory in Nagoya. During this time, I spent several years researching boxed seedlings, and discovered the following shortcomings. box? LIT is used as a young seedling or middle layer, but the nutrients in the seed rice have been almost completely consumed, and on top of that, the power of the seedling itself has not yet been strengthened, so it is transplanted when it is at its weakest. will be done.

He continued to oppose the development of planters. However, despite this basic irrationality, protection of various pesticides, improvement of seedling raising facility equipment, etc. (Thus, box seedling cultivation (mouth transplanter cultivation) has rapidly become popular. However, the current situation is In Japan, a considerable amount of labor is required to raise seedlings in boxes, and it cannot be said that they are sufficient even for seedlings.The rice produced is now mixed with milky white rice, and sometimes unexpected crop failures occur.

し弱いことが明白（こなった。From what I have learned about seed science and from my experience, I believe that the seeds have exhausted their stored nutrients and have not yet been able to strengthen their physical strength.
It was concluded that seed rice with stored nutrients is retained and has better faiability as a seedling than rice seedlings with R. When we tried making a prototype, it became clear that it was vulnerable to adverse conditions such as low-temperature deep water mud.

の両芽切籾苗である。As a means to compensate for this drawback, late-season direct sowing, which waits for the temperature to rise by 1,000 yen, will be adopted. Here, I researched seeds and seedlings for direct-seeded rice cultivation, which can be improved on this rather late direct-seeded rice cultivation, and be carried out about half a month earlier, that is, earlier than the conventional water 1'11 generation period. The reason for this is to make effective use of the high temperature and sunshine in August to increase the fertility of paddy rice, and to reduce the damage caused by typhoons. The double-bud cut rice seedlings of the present invention were developed for the above purpose.
この早期直播をこ成功すれば、晩期直播並びをこ暖地の

ることは、当然の帰結である。If this early direct sowing is successful, it is a natural consequence that late-season direct sowing and direct sowing in warm regions will become easier, safer, and extremely advantageous.

う最短であったとしても、苗であることに変りはない。Components of the Invention Seeds and Seedlings When viewed from the palm of the hand, a seedling with germinated embryonic buds and rooting of the embryonic radicle should be treated as a seedling rather than as a seedling. Even if germination and rooting are at the minimum limit (I decided to call the smallest one of about 1 mm), the seedling raising period is the shortest, 2 to 5 days. Even if there were, it would still be a seedling.

同時にすることが、肝要なのである。Germinating seeds by soaking them has been practiced for a long time. In this case, the germination was about the size of a pigeon's chest. Occasionally, some young buds germinated, but this was only incidental. There are two points: germinating the young buds of the seed rice and rooting the radicle (commonly, this is also called germination) at the same time, and cutting the buds, which is the minimum state of both. The present invention is the first in the theory of paddy rice seedling raising to date that does not consider this as a necessary condition for raising seedlings. The reason why we minimized bud cutting for germination and rooting is because the longer the buds grow, the more stored nutrients will be wasted. Also, long buds and roots can be a disadvantage as they interfere with the coating process with oxygen supplements. It has weaker resistance than seedlings with both sprouts, such as sprouted paddy, sprouted paddy with only young buds, and rooted paddy with only radicles, and has poor growth under adverse conditions such as low-temperature deep water and muddy water. For the reasons mentioned above, it is important to cut both buds at the same time.

順序を逆にして、先に幼根の芽切をしてから、その後で
幼芽の芽切をする方法は、作業が困難になるばかりでな
く、両芽切がそろわない。Originally, seed rice grows first from the germination of young shoots in oxygen-deficient water, and from the germination of radicles in oxygen-rich conditions. Therefore, in order to simultaneously cut both young shoots and radicles, consider the timing of soaking the seeds and cutting the young shoots, and then lift the paddy bag out of the water and expose it to air to ensure a sufficient supply of oxygen. . This lifting out of the water causes them to spread out during draining, stopping the growth of young shoots on the one hand and promoting bud cutting of the radicle on the other hand. The sowing period, including the period for pulling up the rice bags, is often extended to 9-10 days, compared to the previous 5-6 days. Also, for the same reason, the number of baths may be increased from once before. In short,
We must put our emphasis on achieving both goals at the same time and do everything in our power to accomplish them. When cutting both buds in the same order, reversing the order and cutting the radicle first and then the young bud will not only make the work more difficult, but also cause the cutting of both buds to be difficult. They don't match.
次に、両芽切籾苗の実際上の使用法について記述する。Next, the practical use of rice seedlings with both buds cut will be described.

There are many bad conditions. In order to protect them from these adverse conditions, the rice seedlings are coated with a commercially available oxygen supplement, Culper, which is referred to as Culver double-bud cut rice seedlings. This is the normal condition when using double-bud cut rice seedlings.

に種苗の取扱輸送上の効果について述べる。C. Effects of the present invention The effects of the present invention will first be described in comparison with the box surface. If direct sowing machine cultivation with double-bud cut rice seedlings yields the same or better results than rice transplanter cultivation with box-side rice transplanters, then the former double-bud cut rice seedling cultivation eliminates the large labor cost of box-side cultivation. Of course, it is better than that. The results of field cultivation are good as shown below. In an area where the snow has fallen on the north side of Mt. Ibuki and the water temperature of the melted snow is low, Koshihikari cultivar-ryobud-cut rice seedlings are directly sown relatively early in late April, and then grown in mid-September. They were harvested at the appropriate time and shipped to the agricultural cooperative for their first collection. The yield is 1
In a normal year, about 8.5 bales were produced per 0a, and in a good year, about 9.5 bales were produced, which was slightly better than the results of box-sided rice transplanter cultivation in this area. Regarding the quality of the rice, there was no milky white rice mixed in, and it had passed the inspection with a first grade every year, which was better than the results shown on the box. Next, we will add two growth patterns of double-bud-cut rice seedlings in Honda. As you can see from a quick look at Honda's growth conditions, the best and most natural arrangement is to arrange the plants in an upwardly distributed arrangement on the tillers. In addition, the arrangement and growth of seed roots are disrupted by transplanting seedlings, but since double-bud cut rice seedlings are sown directly, they are arranged in the most natural form and continue to grow. It is thought that the normal arrangement and growth of these stems and roots leads to the healthy growth of paddy rice and ensures stable and high yields. On the other hand, in the case of box-faced rice, the arrangement of its stems and roots becomes confused and overcrowded, causing its growth itself to become weakened, resulting in milky white rice and poor harvests. It is assumed that. Next, we will discuss the effects on handling and transporting seeds and seedlings.

る。The boxed rice grown and sold at the rice seedling center is transported on a small truck with a rack, where it is greened for several days using seedlings, etc., and then transported to Honda. These are truly complicated types of labor. After rice planting, there is also the hassle of washing the big boxes.

く手入無用である。この点も箱面よりも優れている。On the other hand, Culver-Ryobud-cut rice seedlings can be transported to Honda in a net bag, which is easy and convenient as the amount to be handled is small. This also applies when shipping from a seedling nursery center. The germination period of cultivar-both-bud-cut rice seedlings varies depending on the temperature, but it is about 10 days, and for practical safety, it can last for several days. During this time, it requires no maintenance at all, just keep it in a mesh bag. This point is also better than the box surface.

不良条件に対し低抗力が強い。即ち次の通りである。Next, we will discuss a comparison between paddy seedlings with both buds cut and budded paddy seedlings. In reality, both are coated with Culper. Culver
Compared to Culper sprouted rice, seedlings with both buds cut have a lower resistance to adverse conditions such as low-temperature, deep water and muddy water. That is, as follows.

５日もあった実験例をみる時、この方面の実用価値も、
検討に値すると考える。When the conditions are slightly favorable, the seedling establishment rate increases by about 10 to 20%, and growth is accelerated for 2 to 3 days. When conditions are unfavorable,
The seedling establishment rate was increased by 50-90% and growth was promoted for 5-9 days. The reason for the difference between the two is that the performance of Culper germinated rice suddenly declines under poor conditions. The excellent effects of the above-mentioned double-bud cut paddy seedlings determine the success or failure of direct-seeding paddy rice cultivation, and they have outstanding value as paddy rice seedlings. In areas with low water temperatures due to melting snow, we carried out early direct sowing in defiance of the current trend, and despite repeated failures that became a source of laughter, we were finally able to catch the light of success. This is because bud-cut rice seedlings had excellent effects. In particular, in contrast to the common failures caused by poor conditions due to low temperatures in the spring of 1986, double-bud-cut rice seedlings demonstrated their superior effectiveness and were successful despite early sowing in cold regions. Furthermore, with the confirmation and success of this excellent effect under poor conditions such as low water temperature and early stage, it is obvious that direct sowing in warm areas and direct sowing in late season will be easier than safer. Furthermore, under large-scale aircraft direct sowing, the above-mentioned excellent effects of both-bud cutting and rice cultivation are
It is presumed that it will exhibit remarkable power. In this way, in the future of direct sowing rice cultivation, which is labor-saving rice cultivation,
I surmise that all of them will use double-bud cut rice seedlings. In particular, the germination period of fully air-dried double-bud cut rice seedlings is 8.
When looking at an example of an experiment that lasted for 5 days, the practical value of this aspect is also evident.
I think it is worth considering.
