Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to growing plants during cultivation.

[0002]

2. Description of the Related Art Fertilizers for soil cultivation and hydroponics that have been conventionally used have three major nutrients, nitrogen source, phosphorus source and potassium source, necessary for growing plants as main components. By adjusting the compounding amount, petals, edible agricultural products, ornamental plants, etc. are fattened.

[0003]

However, the above-mentioned conventional fertilizers are intended for the purpose of fattening the plant during cultivation, and the life of the plant after cutting is not considered, and the plant after cutting is For example, life extension treatment is merely performed using a life extension agent as disclosed in JP-A-3-130201. The present invention, in the case of petals, does not undergo life extension treatment again after being cut flowers, and retains high quality equal to or higher than those subjected to life extension treatment. The purpose is not only to retain the (flower) shade without fading, but also to improve the yield of edible agricultural products over conventional fertilizers during cultivation, thereby increasing the yield rate.

[0004]

[Means for Solving the Problems] The inventors of the present invention have considered that trace metal elements other than the above three major nutrients act physiologically actively in the growth of plants. As a result of exploring various metal compounds, they have found that a lanthanoid series rare earth element, which is not contained in conventional fertilizers, can perform this action, and completed the present invention.

That is, the present invention is a fertilizer for growing a cultivated plant in which a compound of a lanthanoid series rare earth element is contained in a fertilizer, and when a plant is cultivated in soil or hydroponics, a compound of a lanthanoid series rare earth element is used. Is added to fertilizer or is applied to fertilized soil or hydroponic culture medium to grow a cultivated plant.

The lanthanoid series rare earth element compound may have any structure of an inorganic salt, an organic acid salt and a complex, but it has a large solubility in water, that is,
Chlorides, bromides, iodides, nitrates, perchlorates, bromates and the like are preferable. The compound of these lanthanoid series rare earth elements may be a compound of a single element or a mixture of compounds of two or more elements at any ratio. In order to obtain these mixtures, ore such as celite (cell ore), lignite ore, ortite, monazite (monaz ore) may be refined as a raw material, but when ore is used as a raw material,
Several refining steps are required to obtain the target. Therefore, in order to obtain the target product more easily, it is preferable to use misch metal (cell mixed metal) as a raw material. As an example of the components of misch metal, the total content of rare earth elements is 99.05%, and the abundance of each element in them is lanthanum 26.9% and cerium 51.58.
%, Praseodymium 5.19%, neodymium 16.18
% And samarium 0.15%. In addition, 0.3% magnesium, 0.11% aluminum, 0.09 silicon.
%, Iron 0.45%, but the presence of elements other than these rare earth elements does not hinder the effect of the present invention for improving plant growth. The content of rare earth elements in the misch metal is slightly different depending on the time of acquisition, but in any case, accounts for about 99% of the total.

To obtain a mixture of rare earth element compounds of the lanthanoid series from misch metal, the simplest method is to treat this with a mineral acid. For example, by adding an excess of concentrated hydrochloric acid to Misch metal to dissolve it, and evaporating it to dryness, a mixture of rare earth element compounds (hereinafter, abbreviated as Misch metal chloride) which is a target substance of a yellow powder is obtained. Be done. A mixture of this misch metal chloride with a fertilizer is one of the fertilizers of the present invention, and contains 0.01% to 0.1% of misch metal chloride in the fertilizer. Further, one of the implementation of the method of the present invention, misch metal chloride, by mixing the fertilizer in advance, or by spraying or dripping on the cultivated soil or hydroponic culture medium in the state of powder or aqueous solution. To do. In the case of soil cultivation, 0.01% to 0.1% in the powder mixed fertilizer in the case of soil cultivation, and 0.0005% to 0% against irrigation in the case of hydroponic cultivation.
About 005% should be mixed.

[0008] When a water-soluble lanthanide series rare earth compound is given to a cultivated plant, its physiological action on the plant and the mechanism for the plant to receive it are not clear, but for example, misch metal chloride was given. Hydroponically grown roses not only bloom earlier than those that are given only irrigation, but also when cut flowers are used, the life-prolonging effect and discoloration of petals can be clearly suppressed. Also, the result is that the amount of kidney beans harvested by compost soil cultivation with misch metal chloride exceeds the yield of those grown only with compost.

[0009]

The present invention will be described below with reference to examples.
The present invention is not limited to this. [Example 1] Hydroponically cultivated roses were used as test plants and were cultivated only by giving irrigation (untreated section), and those cultivated by giving irrigation with addition of misch metal chloride (treated section) ), The difference in flowering time and the degree of discoloration of petals after cutting them were observed. The amount of perfusate is 60 liters for each 1200 roses, which is pumped 7 times a day and dispensed in drops.
ml will be supplied. For the test roses, pick 15 flowers each with a bud that will be flowered 5 and 9 days after picking each bud so that one bud will be attached to each.
Further, each group was divided into 5 groups of 3 groups, 1 group was a non-treated group, and 4 groups were treated groups, and each treated group contained an irrigation solution containing 0.125 mg to 1.125 mg of mischmetal chloride per strain. Solution was given daily and treated as above for 5 and 9 days. The temperature in the greenhouse during the treatment period was 38 ° C to 40 ° C. In the evening of the last day of processing, cut flowers and arrange them in water, then drain them again the next day.
Each group was observed by immersing it in 400 ml of water. For the process of aquaculture and transportation overnight after cutting, see 5
Although the treatment was carried out at room temperature in the daily treatment group, ice-cooled water was used in the 9-day treatment group. In the observation of cut flowers, the first two days in the treatment group for 5 days were carried out at room temperature for the first 2 days, and the treatment was carried out in the constant temperature room (20 ° C to 22 ° C) from the third day. It was carried out in a temperature-controlled room. The observation results are shown in Tables 1 to 4. In Tables 1 and 3, x indicates a bud state, * indicates a bud bulge, ● indicates a bud open state, ○ indicates a half-opened flower state, and ⊚ indicates a flowering state. In addition, Table 2 and Table 4
Indicates the degree to which the petals change color from red to purple.
× indicates no change, ☆ indicates light purplish red, ● indicates purplish red, ○ indicates magenta, and ⊚ indicates purple.

It is observed that the flowers of the treated plot flower earlier than the flowers of the untreated plot. Regarding the discoloration of petals, it is observed that the discoloration in the treated section is suppressed. In particular, the effect is exerted in the treatment group in which the single dose of mischmetal chloride is 0.250 mg / 50 ml (0.0005%).

Example 2 Soil-cultivated kidney bean was used as a test plant and was grown only on compost (untreated section), and on the same compost soil was given misch metal chloride as an aqueous solution (treated section). ) Was compared with the harvest amount of beans (with pods) in both plots during a certain period. The upper two sides are 5
Prepared 3 planters of 8 cm and 18 cm, and 16 cm in height, put compost soil (rice husk compost soil) to a depth of about 6 cm, and mix the same amount of compost soil and soil on it. Was laminated to a depth of about 6 cm. Each planter was sowed at 3 locations and 3 seeds at each location, and after 9 days, one seed with the best growth was left and the rest was picked.
Of the three planters, one is untreated and the other two
The individual was treated. In the treated area, an aqueous solution of mischmetal chloride was applied from the time of seed sowing to the vicinity of the center of the seed seeding area. The aqueous solution is 0.01 (once in the evening) once a day for one location (or one) in the first treatment area.
1 ml of 25 mg / ml concentration and 1 ml of 0.125 mg / ml concentration were given to the second treatment group every other week.

Twenty-one days after sowing the seeds, gravel soil was laid and the beans were grown and the length of pods exceeded 10 cm.
We harvested over a week and weighed everything. still,
On the last day, all beans were picked and added to the harvest. When comparing the yields from the untreated and treated plots, the yield from the first treated plot was only 2% higher than that from the untreated plot. The treated area showed an increase in yield of about 11% compared to the untreated area.

When green beans are grown with a chemical fertilizer, the amount of fertilizer applied and additional fertilizer before seeding is about 5 g per strain, respectively. Also, in this Example, the total amount of misch metal chloride administered during the implementation period (about 50 days) was about 0.6 mg in the first treatment section and about 1 mg in the second treatment section. Assuming that the material was mixed with the chemical fertilizer and applied, the chemical fertilizer was about 60 ppm in the first treatment area and about 100 p in the second treatment area.
It means that fertilizer is applied to each pm.

[0014]

As is apparent from the above examples, the present invention provides a fertilizer to which a rare earth compound of the lanthanoid series is added to a cultivated plant, or does the same compound are added to the fertilizer during its growth? Or, by administering the same compound to fertilized soil or hydroponic culture medium, while improving the growth of plants during cultivation, it is also possible to promote the life of the plant after cutting, especially, in the flower plant, Prevents discoloration of petals,
With real plants, the yield can be increased.
