JPS6222705A - Promoter for rooting and taking root of rice plant - Google Patents

Abstract

PURPOSE:The titled promoter for treating seedling of rice plant before transplanting, promoting rooting and taking root of seedling of rice plant after planting, improving tillering, containing lecithin known as the most safest fungi cide or acetylcholine known as a neutrotransmitter of animal. CONSTITUTION:An aqueous solution of a promoter for rooting and taking root of rice plant wherein a lecithin such as soybean lecithin, egg lecithin, etc., or an acetylcholine such as acetylcholine hydrochloride, etc., is watered to the root of seedling of rice plant before transplanting of rice plant, preferably by 10 days before transplanting. In the case of the lecithin, the ratio of the application is 30-2,000mg, especially 60-1,000mg based on a seedling box of 60X30cm, and in the case of the acetylcholine, the ratio is 5-200mg, preferably 10-100mg. EFFECT:Usable for cultivation of rice plant in a cold area.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a novel rice rooting and rooting promoter.

More specifically, the invention relates to a rice rooting and rooting promoter characterized by containing lecithin or acetylcholine.

[Prior art]

Conventionally, lecithin has been used in the agricultural field as the safest fungicide for crops (against powdery mildew, etc.). Acetylcholine is also known as a neurotransmitter in animals. However, it has been reported that rice seedlings were treated with lecithin or acetylcholine to promote rooting and rooting.
There are no complaints.

[Problem that the invention seeks to solve]

Improvements in rice varieties and cultivation techniques have made it possible to grow rice in cold regions. However, one of the problems with rice cultivation in cold regions is that when rice seedlings are transplanted into rice fields, it is difficult for the seedlings to take root due to the low temperature.

The present invention aims to improve these problems. That is,
By treating rice seedlings before transplanting with a solution of lecithin or acetylcholine, the rooting and establishment of rice after transplanting into Honda is promoted and the tillage becomes good.

[Means to solve the problem]

In the present invention, examples of lecithin include soybean lecithin,
Examples of acetylcholine include egg lecithin and acetylcholine hydrochloride. However, the present invention is not particularly limited to these lecithin or acetylcholine.

These lecithin or acetylcholine can be used in any conventionally known dosage forms such as powder, aqueous solution, emulsion, aqueous or oily suspension.

The amount of the present invention agent to be used depends on the variety of rice, the growth stage of rice,
Although it differs depending on the method of use or the time of use, in general, the roots of rice seedlings are irrigated with an aqueous solution before transplanting, preferably at least 10 days before transplanting. In this case, the amount of lecithin is 60
Generally 30~200 per x 30cm seedling box
0 ■, preferably 60 ■ to 1000 ■. Further, the amount of acetylcholine is generally 5 to 200II1g, preferably 10 to 100mg.

The agent of the present invention is generally used in the form of an aqueous solution, but it can also be used in combination with liquid fertilizers, insecticides, fungicides, etc.

[Operation and effects of the invention]

By treating rice seedlings before transplanting with an aqueous solution of the agent of the present invention, rooting and rooting of rice seedlings after transplanting into Honda are promoted, and the tillage becomes good.

〔Example〕 The following examples further illustrate the invention.

[Example 1] Three paddy rice seeds sterilized with Henleto T (200 times solution)
Germination was carried out in a thermostat at 2°C. Two days later, dried paddy (100 g/box) was sown in a seedling box filled with artificial bed soil, and the seedlings were kept in a seedling box at 32°C for 2 days.

After germination, they were kept in a plastic greenhouse. Five days before transplantation, each dose of soybean lecithin and acetylcholine chloride was diluted with 500 ml of water, and one box of each was irrigated. Thirty-five days after sowing, the plants were transplanted by hand into Honda, and a growth study was conducted one month after transplanting. The results are shown in the table below.
