も考えられる。The reason why the dressing aid of the present invention is used is that the amount of heat generated when it is hydrated is large and the amount of water vaporized is large, and the crystallization of powder is quick and easy to dry. It should be easier to dress than when using it as an auxiliary agent. The seeds should be dressed and have good physical properties. In particular, the addition of basic substances improves stability. The results of cultivation tests on paddy rice are good. Regarding the cultivation results, it is presumed that magnesium sulfate has a function of enhancing energy efficiency when seed endosperm is converted into germination or germination energy by the action of oxygen from peroxide, but other As a reason, a combined effect of a plant growth nutrient effect, an effect of enhancing energy efficiency, and a plant growth nutrient effect may be considered.

となる。The amount of agricultural oxygen supply containing seed dressing aids applied to seeds is
Although it depends on the type of seeds, application conditions, etc., it is necessary to secure the necessary amount of available oxygen (called AO). Normally, for direct seeding cultivation in submerged soil, the AO concentration is about 7-8%. To do. Oxygen supply for agriculture depends on moisture, storage conditions, etc.
Since the AO concentration changes over time, keep the water content below 1%, use packaging materials that do not absorb moisture, or store in a cool, dark place. The thus-obtained agricultural oxygen supply agent is suitable for direct seeding cultivation of paddy rice in submerged soil, and for dressing seeds for seeding for cultivation of other crops.
