Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for cultivating grass.

[0002]

2. Description of the Related Art Conventionally, it is known that livestock happily eat pasture near the coast and the meat quality of the livestock eaten is good in some places. The term "meat quality" as used herein means the quality of meat judged by the color tone, elasticity, aroma, the amount of cholesterol, the amount of fat, the taste, etc. which are usually used for judging the commercial value of meat.

[0003]

However, it is not known why the livestock is willing to eat pasture near the coast and the meat quality of the livestock is good. In addition, there is no known means to feed livestock. Moreover, the sugar content of grass has not been measured so far.

The present inventor has found that salt increases the sugar content of grass. In addition, the present inventor has found that livestock is willing to eat grass having a high sugar content. In addition, the present inventor has found that the meat quality of the livestock that ate the grass having an increased sugar content is good. Further, the inventor of the present invention has a sugar content of about 5 to 6 degrees in the grass near the coast where the livestock are willing to eat, whereas a sugar content of the grass in the inland area is about 3 to 4 degrees and the livestock is near the coast. It was found that they are willing to eat the grass because of its high sugar content. Therefore, one of the objects of the present invention is to increase the sugar content of grass to about 5 to 6 degrees. However, since grasses die easily due to salt content, it is extremely difficult to increase sugar content while preventing death. Therefore, another object of the present invention is to provide a suitable method for increasing the sugar content of grass to about 5 to 6 degrees while preventing mortality. Still another object of the present invention is to provide grass having a sugar content of about 6 to 8 degrees. Still another object of the present invention is to
It is to provide grass with a sugar content of about 6 to 8 while preventing death. These objects are achieved by the present invention.

Means for Solving the Problems The present invention comprises (1) a step of spraying 50 to 200 kg of a rooting accelerator as a silicic acid component per 10 a on the ground surface, and (2) a salinity concentration on a leaf surface and a ground surface of a grass. 0.1 to 0.3% by weight of salt water or seawater 3 per 10a
The method for cultivating grass is characterized in that it has a step of vertically spraying from 0 to 1000 kg. Here, "livestock" means cows, horses, sheep, pigs and chickens. The "sugar content" refers to the nutrient solution concentration (Brix) of grass, which is measured by a simple sugar content meter using the principle of light refraction. The term "salt content" refers to salts contained in seawater in addition to salt. Also,
"Grass" means corn, sorghum,
Forage crops such as oats.

[0006] As a rooting accelerator, silica com or calcium compost containing a considerable amount of silica is used. As the calcium compost, the calcium compost of Patent No. 1343663 according to the present invention can be used. Salt water or seawater having a salt concentration of 0.1 to 0.3% by weight can be easily prepared by adjusting or diluting the concentration of salt water or seawater with water. Sea water is preferable to salt water because it contains many trace components. "Up-down application" is referred to as up-down application because it is applied to both the leaf surface of grass and the ground surface. When the desired sugar content cannot be obtained in the steps (1) and (2), the desired sugar content can be easily obtained by repeating the step (2). The sugar content can be easily measured with a simple sugar content meter. The amount of salt water or seawater sprayed is generally larger than the amount of pesticide sprayed and preferably smaller than the amount of liquid fertilizer sprayed, and is 3 per 10a in total.
It is from 00 to 1000 kg. If it is more than 1000 kg, the grass is likely to die, and if it is less than 300 kg, the spraying effect is poor. Usually, the vertical spray amount of salt water or seawater is 300 to 500 kg per 10 a.

[0007]

When the rooting promoter is sprayed, the grass produces a large amount of active roots near the ground surface due to the action of active silicon in the rooting promoter (the effective amount of roots increases). By the action of a large amount of active roots, even if salt water or seawater having a salt concentration of 0.1 to 0.3% by weight is sprayed, a high sugar content can be achieved without dying the grass. 50-200 per 10a as silicic acid content
The reason why the rooting accelerator is sprayed in an amount of less than 50 kg is less effective, and more than 200 kg is easily wasted. The reason for defining the salt concentration as 0.1 to 0.3% by weight is that the grass is likely to die when it is higher than 0.3% by weight, and the spraying effect is poor when it is lower than 0.1% by weight. Calcium contained in silica and calcium compost is involved in the formation of cell membranes of grass, neutralizes organic acids in soil, participates in protein synthesis and nitrogen fixation by rhizobia, and promotes root development. , Improve soil acidity and physical properties.

[0008]

INDUSTRIAL APPLICABILITY The present invention can be easily applied to grassland inland where it is difficult to obtain seawater. The grass cultivated by the method of the present invention has a remarkably high sugar content of about 5 to 6 degrees or higher, and sometimes reaches about 6 to 8 degrees. Therefore, livestock are happy to eat and the meat quality of livestock is good. The present invention eliminates the use of dangerous body tissue and meat-and-bone meal (ruminant tissue).
