JPS61282303A - Growth regulator for sugar cane - Google Patents

Abstract

PURPOSE:To provide the titled regulating agent containing a choline compound as an active component, exhibiting the effect to promote the rooting and growth of sugar cane by the treatment of the seedling of sugar cane before transplantation and giving a well-grown seedling having increased roots. CONSTITUTION:The objective agent contains one or more compounds selected from choline, phosphorylcholine and their salt as active component. The choline salt is inorganic acid salt such as hydrochloride, sulfate, silicate, carbonate, etc., or organic acid salt such as acetate, citrate, lactate, L(+)-tartrate, etc., and the phosphorylcholine salt is e.g. phosphorylcholine sodium salt, phosphorylcholine calcium salt, etc. The agent is used in the form of powder, aqueous solution, aqueous or oil suspension, etc. Preferably, a seedling is immersed in a liquid containing 10-1,000ppm of the active component for 1-24hr. EFFECT:Since the seedling is treated by immersion, the treatment can be carried out easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel growth regulator for sugarcane.

More specifically, the invention relates to a growth regulator for sugarcane characterized by containing one or more compounds of choline, phosphorylcholine, and salts thereof (hereinafter these compounds are referred to as cholines).

[Prior art]

It has been known that rooting can be promoted by immersing sweet potato seedlings in a choline solution. Also E
thephon (2-chloroethyl ph
osphon-ic acid) is the rooting agent of sugarcane,
It is known to have growth regulating effects such as growth promoting effects.

However, it has not been reported that immersing sugarcane seedlings in a choline solution has growth regulating effects such as promoting rooting and growth.

[Problem that the invention seeks to solve]

In sugarcane cultivation, rooting from seedlings and sprouting of buds often occur unevenly. Promoting the rooting and germination of seedlings and producing uniform seedlings leads to high production of sugarcane, so various methods have been tried so far. The above E
It has been reported that thephon promotes the growth of seedlings by spraying them on adult sugarcane plants three weeks before cutting the seedlings. However, in practice, it has been extremely difficult to spray chemicals on adult sugarcane plants that are over 3 meters long.

The present invention ameliorates these problems.

That is, immersing sugarcane seedlings in a choline solution before transplanting has the effect of promoting rooting and growth of sugarcane.

[Means to solve the problem]

The choline compounds which are active ingredients in the present invention include the following compounds.

Choline, or its hydrochloride, phosphate, polyphosphate,
Inorganic salts such as sulfates, nitrates, silicates, carbonates, organic acid salts such as acetates, citrates, lactates, L(+)tartrates, etc., and phosphorylcholine, phosphorylcholine chloride soda salt, phosphorylcholine chloride Indicates calcium salt, etc.

The growth regulator of the present invention containing these cholines can be formulated into any conventionally known dosage form such as powder, aqueous solution, aqueous or oily suspension.

The concentration when using the present invention agent varies depending on the soaking time of the sugarcane, etc., but generally sugarcane seedlings are mixed with 10 to 11,000 pp, preferably 20 to 200 pp, before transplanting.
Soak in ppm choline solution. Soaking time is 1-2
4 hours is preferred.

The agent of the present invention is generally used in an aqueous solution, but it can also be used in combination with liquid fertilizer, insecticide, fungicide, etc.

Next, the physical properties of cholines are shown.

Compound Properties [Actions and Effects of the Invention] By treating sugarcane seedlings before transplanting with an aqueous solution of the agent of the present invention, the amount of rooting of the seedlings after transplantation is increased, bud development is also promoted, and the seedlings are improved. Growth is good.

In particular, since the seedlings are immersed in the treatment, the treatment work can be carried out easily.

〔Example〕

Next, the present invention will be explained in more detail with reference to Examples.

Example 1 After preparing sugarcane seedlings (two-node seedlings), they were immersed in an aqueous solution of choline chloride at a predetermined concentration for 3 hours and placed face down on a sand bed filled with sand in a temporary frame measuring 60 x 60 cm.

The tests were conducted in two consecutive sessions, with 10 samples per ward. The survey was conducted on the 25th day after surrender. The results are shown in Table 1.
