Abstract

PURPOSE:To suppress luxuriant growth of weeds, by scattering lactic acid or lactic acid bacteria on stems and leaves or seeds of plant and plowing. CONSTITUTION:Lactic acid or lactic acid bacteria are made into a proper concentration, sprayed on steam and leaves of plant or seeds dropped on the ground, immediately decomposition of the stems and leaves is promoted and the seeds are germinated and withered without dormancy in soil to suppress luxuriant growth of weeds. The lactic acid bacteria have strongly decomposing action on organic substances and make the substances effective, weeds and rice straws plowed into soil are converted into high-quality organic substances in the soil.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves spraying lactic acid bacteria at an appropriate concentration on the leaves and seeds of plants, and then immediately plowing to promote the decomposition of the leaves and seeds. This article relates to a weed control method using microorganisms that suppresses overgrowth.

The secondary destruction of ecosystems and deterioration of soil due to the use of herbicides has long been a problem, and various herbicides have been developed, but there are almost no herbicides that can address the problem of environmental pollution.

Weeding in agriculture requires an extremely large amount of effort, and even though we are aware of the harmful effects of herbicides, we currently have no choice but to rely on herbicides. As a result of various studies to solve this problem, the present invention was developed based on the findings that lactic acid or lactic acid bacteria quickly decompose organic matter at room temperature, and that seeds treated with lactic acid or lactic acid bacteria have thinner seed coats and a dormancy function. It became clear that it would be destroyed. By focusing on these characteristics and treating them using a completely different method from conventional herbicides, we succeeded in suppressing not only perennial grasses but also most seed-germinating weeds, including barnyard grass in rice fields.

Specifically, lactic acid bacteria cultured in molasses as a medium is sprayed on the leaves and seeds that have fallen on the ground, and the soil is tilled immediately, but if there are too many weed seeds and the effect is not sufficient, the method is to spray the seeds after a few weeks. By repeating the same treatment, it became possible to almost completely suppress weeds. This method is suitable for rice fields and
Although it is effective in all fields, it is especially effective in paddy fields after autumn harvest, and it has been confirmed that most seeds whose dormancy function has weakened will wither during the low temperature period in winter. Treatment in early spring has the same effect, but in paddy fields with a lot of weeds, it is desirable to treat twice in autumn and spring. In addition, it is easy to suppress the growth of weeds by spraying a water solution on the ground surface in the summer and plowing it in after the seeds on the surface have germinated at the same time.

In addition, lactic acid bacteria have a strong ability to decompose and activate organic matter at room temperature, so weeds and rice straw that have been plowed in can be converted into high-quality organic matter in the soil. It has the property of being both effective and effective.

Common chemical herbicides reduce the activity of soil microorganisms,
Furthermore, it is impossible to utilize dead weeds as soil fertility, and it has been desired to develop a harmless and effective herbicide like the present invention that activates the activities of soil microorganisms. The present invention can fully meet these demands.

Example 1 Lactic acid bacteria cultured in a molasses medium were sprayed with 1 ton of i,ooo double solution per 10a on a harvested paddy field without the use of herbicides,
The field was plowed with rice straw to confirm its weeding effect for the next year. We also investigated areas that were treated twice, once in the fall and once in the spring. (Survey area: 12-1 Fujishima-cho, Fukui City) No treatment Autumn treatment Autumn/spring treatment Number of times of manual weeding in the following year: 5 times IUgJ weeding time per time
50 hours 6 hours 2 hours Example 2 The same lactic acid bacteria as above was sprayed on a field where perennial grasses such as fly millet and macacia were growing, so that the stems and leaves and fallen seeds on the ground surface were sufficiently wet, and the plot was immediately plowed for 2 weeks. Later, we confirmed the weeding effect of the plots that were re-treated and cultivated.

(loa spray lk = 1 ton with 1.000 times solution) The investigation was conducted 30 days after each treatment. (Survey area: Nakama 116, Onna Village, Okinawa Prefecture) No treatment 1 treatment 2 treatments Number of weeds per M2 14,368 276 12 or more As is clear from the results, the use of lactic acid bacteria is a practical method for weed control. It is clear that this method is extremely effective.
