Problems solved by technology

[0003] Traditional fungal herbicides are highly specific and often only remove one type of weed
In addition, the active ingredients of traditional fungal herbicides are fungal spores, which are mainly produced by fermentation technology, but fermentation production has problems such as high labor investment, easy production of by-products, ...

Embodiment Construction

[0022] A fungal-type field weed inhibitor, taking the suppression of weeds in rice seedling beds as an example, is a soil-sand mixture containing arbuscular mycorrhizal fungi, which contains spores of the fungus, roots infected by the fungus, and hyphae outside the root , the arbuscular mycorrhizal fungus is Glomus mosesi HDSF1, and corn, white clover and rice are used as hosts to propagate Glomus mosesi. Among them: the arbuscular mycorrhizal fungus is Glomus mosei HDSF1, which is preserved in the General Microorganism Center of China Committee for the Collection of Microorganisms, and the preservation number is CGMCC No.3012. White clover seeds were purchased from Shenyang Bianpo Zhisheng Bag Factory (Tel: 024-89150311; Contact Address: Shancha Street, Sujiatun District, Shenyang City). Corn and rice seeds were purchased from the Xuefu Road Seed Sales Department of Heilongjiang Seed Company (Tel: 0451-1394814043; Contact Address: No. 368, Xuefu Road, Nangang District, Harbin...

Abstract

The invention relates to a fungal field weed inhibitor which is a soil and sand mixture comprising arbuscular mycorrhizal fungi and internally comprises strain spores, a root system infected by the fungi and external hyphae. The arbuscular mycorrhizal fungi are glomus mosseae HDSF1; corns and white clover are used as host reproduced glomus mosseae; production of the fungal field weed inhibitor is carried out in the root system of a host plant of the fungal field weed inhibitor. The fungal field weed inhibitor has the characteristics of low labor cost, no generation of side products, no requirement for separating active ingredients, easiness for keeping the aseptic condition, and easiness in the production condition control and the like, has a small application rate and high environmental suitability and has a strong inhibiting effect on five common weeds in the field.

Description

technical field [0001] The invention relates to a fungal field weed inhibitor, and also provides a preparation method of the fungal field weed inhibitor. Background technique [0002] Weeds are an important part of the farmland ecosystem, and they are also one of the important factors that affect the growth of crops and lead to a decline in yield. Taking rice as an example, the yield of rice due to weeds decreases by up to 25% every year. In China, 15 million hectares of paddy fields are damaged by weeds, and 10 million tons of rice are lost every year, with a loss rate of over 15%. The specific reason is that the rice seedling field soil contains more weed seeds, so that the rice seedling field has many kinds of weeds with a high density, and the rice seedlings are thin, short, with few leaves and few tillers. In order to make rice seedlings the dominant population in this ecosystem, farmers use a large amount of chemical herbicides to control weeds. However, chemical he...
