The present invention relates to soil for raising seedlings that achieves seedlings with mechanical strength that prevent the soil attached to the roots from coming off when transplanting the seedlings. Currently, various shapes of seedling containers have been developed for vegetables, flowers, rice, etc., and growing and transplanting of seedlings with soil is becoming more common. When transplanting seedlings with soil, it is possible to transplant them mechanically because there is little damage to the roots or damage to the plants, and they have good rooting, and instead of handling the plant itself, the roots of the seedlings with soil are handled to avoid damage to the seedlings. This has advantages such as making it possible to save labor. However, the seedling cultivation soil currently in use is not designed to strengthen the root ball, which tends to collapse or chip during transplanting, which reduces the efficiency of transplanting operations. As a countermeasure to this, methods have been taken, such as using soil to which fibrous organic materials such as peat moss have been added, or using wet soil made into a clay bed to increase the adhesive strength of the soil particles themselves, but mixing and kneading are difficult. This method has disadvantages such as being labor-intensive and inhibiting the growth of young plants due to reduced soil aeration, and the strength of the root ball is also unsatisfactory. In view of the above-mentioned circumstances, the present inventors have conducted intensive studies and found that by mixing a specific polymer into soil as a binder, it can be easily used, does not inhibit the growth of young plants, and has sufficient roots at the time of transplanting. The present invention was achieved by discovering soil for raising seedlings that can produce seedlings with soil that have the strength of pots. That is, the present invention

It may contain a regulator, a sacrificial substance such as nitrofumic acid, and a mineral powder effective for improving water retention and fertilizer retention such as bentonite and zeolite powder.
The soil used in the present invention may be in powder or granular form, but granulated soil is preferable since it is easy to obtain the caking effect of the present invention even if the amount of adhesive substance added is small. More preferably, the particle size is 0.5
It is desirable to have granules of ~3.0 mm. In the present invention, the acrylamide copolymer mixed with soil is

[Formula] Unit content is 0.01 to 25 mol%, preferably 0.1 to 5 mol%
It is. If the content exceeds 25 mol%, the strength of the root ball will decrease, which is not preferable. On the other hand, if it is less than 0.01 mol%, no effect as a copolymer will be exhibited. The amount of the copolymer added to the soil is 0.05 to 5% by weight, preferably 0.1 to 3% by weight, based on the soil. If it is less than 0.05% by weight, the soil will not have sufficient cohesive strength, and if it exceeds 5% by weight, the cost will increase.
This is undesirable because the soil sticks when pouring into seedling containers, making it difficult to work with, and may inhibit the growth of some crops. Methods for making seedling raising soil with the above concentration include a method of mixing the copolymer and soil all at once, and a method of preparing a master batch soil containing a high concentration of copolymer in advance and then mixing this with soil to reach a predetermined concentration. be. When raising seedlings using the seedling raising soil of the present invention, for example, there is no need to purchase and mix peat moss, and there is no need to worry about problems such as re-separation of peat moss and soil when filling soil into seedling raising containers. It's good. Alternatively, there is no need to go through the hassle of making a clay bed and packing it in. The packed soil has large pores and good ventilation and water permeability, so growth is smooth and unrestricted. Therefore, the soil for raising seedlings of the present invention, which is simple and easy to use, does not inhibit growth, and provides sufficient root ball strength during transplanting, can be used for seedlings in soil to improve rooting, and can be used mechanically or by hand. It is possible to ensure the efficiency of transplantation and has significant economic and practical effects. The soil for raising seedlings of the present invention can be used for vegetables, flowers, seedlings, rice, etc., and the target plants are not particularly limited. For example, for paddy rice, even when seedlings are grown in a conventional flat-shaped seedling box and transplanted using a normal paddy rice transplanter, the so-called pine strength is improved, and even in the case of thinly sown mature seedling transplants, the roots do not fall apart. This has the advantage of preventing transplanting troubles such as the soil coming loose or the seedlings losing their position due to accurate posture and positioning. For vegetables, there is a growing momentum to develop transplanters for seedlings with soil, and they are beginning to become popular.
It has a great effect. Details will be illustrated in Examples below, but the present invention is not limited thereto. Example (1) Preparation of cultivation soil As a base soil containing fertilizer, "Kumiai granular cultivation soil H" (manufactured by Hokkai Sankyo Co., Ltd.), which is used for raising rice seedlings in cold regions, is used. , N=1.0g, P2O5 = 2.0g , K2O
=1.7g. The water used was 15% to 17% in terms of water content. To 20 kg of this soil, 200 g of each of the four types of acrylamide polymers in the table below were added, mixed and stirred for about 5 minutes with a 60-volume concrete mixer.
Various types of soil for raising seedlings were obtained. (~) In addition to this, untreated "Kumiai granular culture soil H" to which no polymer was added was prepared. ()

[Table] In addition, in the lettuce test, slaked lime was used to
We used potting soil adjusted to 6.0. (2) Lettuce test Prepare 5 paddy rice seedling boxes separated by plastic sheet partition boards so that there are 20 x 10 = 200 small sections, use 1 seedling box per culture soil, add soil, and lettuce. 200 seeds of (cultivar GL-54) were sown in each plot (1 seed/plot), lightly covered with soil, watered thoroughly, and raised in a greenhouse. At the 3.0 to 3.5 leaf stage, the plants were watered appropriately in the morning and subjected to a drop test in the afternoon under moderately moist soil conditions. From each section (by soil type), 100 lettuce seedlings each with a root ball of approximately 2.7 cm square were randomly selected, excluding the partition board inside the nursery box, and the root ball was placed in the ground from a height of 0.7 m. The strength of the plant was determined by letting it fall naturally with the plant facing down, and checking whether or not the root ball collapsed. The results are shown in Table 2 below, and it can be seen that the soil for raising seedlings of the present invention (,) has strong root ball strength and is highly practical.

[Table] (3) Test on paddy rice A total of 20 paddy rice seedling boxes were used, and soil was filled using the conventional method. As a sowing,
After watering and covering with soil, the seedlings were raised in the greenhouse for about one month.
At the average leaf age of 3.5 leaves and 4 to 4.5 leaves, two pieces of each cultured soil group were run through a rice transplanter to determine whether the so-called pine strength was sufficient. The results are shown in Table 3, and it can be seen that the soil for raising seedlings of the present invention does not hinder rice planting at the mid-seedling and adult seedling stages with thin sowing. In particular, in cold regions, there is a growing tendency to sow thinly and transplant mature seedlings (large seedlings), but this problem has arisen due to weak root connections and lack of pine strength. It can be said that the use of soil has great economic and practical effects.
