Plant fermentation extract for preventing and controlling moss in paddy field, and preparation method thereof

Abstract

The invention relates to the technical field of crop prevention and treatment, and particularly discloses a plant fermentation extract for preventing and controlling moss in a paddy field, and a preparation method thereof. The plant fermentation extract for preventing and controlling moss in a paddy field is prepared through fermenting, extracting and pulverizing the following raw materials, by weight, 0.2 to 0.3 part of earthworm powder, 25 to 30 parts of radix sophorae flavescentis, 20 to 25 parts of cyrtomium fortunei, 0.2 to 0.3 part of pollen, 0.20 to 0.25 part of cordyceps sinensis, 10 to 15 parts of salicornia europaea, 10 to 15 parts of liquorice, 20 to 25 parts of adenophora stricta, 15 to 18 parts of oyster shell, 0.10 to 0.20 part of zinc-enriched yeast and 0.10 to 0.15 part ofchromium-enriched yeast. Raw materials are easy to obtain, the preparation process is simple, the microhabitat of the paddy field is effectively improved, the number and activity of effective microorganisms in the paddy field are increased, rice growth is facilitated, the yield is increased, the quality is improved, and the plant fermentation extract is suitable for wide promotion and application.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of crop prevention and control, in particular to a plant fermented extract for preventing moss in paddy fields and a preparation method thereof. [0003] (2) Background technology [0004] In the planted rice fields, during the water pipe period, a lot of moss will grow under the water surface, and these mosses include filamentous green algae such as Spirogyra, Double Star Algae, Transplate Algae, and Hydronetella. The moss covered the paddy field, which seriously affected the development of the rice root system and the absorption of nutrients. The moss reproduces and grows fast, and absorbs a large amount of rice field fertilizer, and more than 80% of the fertilizer is absorbed by the moss. The fertilizer content is 60, which causes the malnutrition of rice growth. Moss has tenacious vitality. As long as the paddy field receives water, the moss will multiply and grow, and spread to the whole fie...

Problems solved by technology

[0005] General chemical herbicides cannot remove moss in paddy fields very well, and manual removal is labor-intensive and labor-intensive, and the effect is not good

However, the rice field fish farming in our country has a long history and continuous practical experience. However, even though carp like to eat moss, the control effect on moss is still unsatisfactory due to the unoptimistic fish output and the lack of careful management.
