Abstract

The invention discloses a method for screening of paddy rice with weed inhibiting function in laboratories. In the method, the paddy rice is promoted to form seedlings by utilizing the characteristic that root and rhizosphere agar extract of a new rice variety with the obvious weed inhibiting function can inhibit the growth of weeds obviously and by agar culture so as to obtain the root and rhizosphere agar extract quickly; and barnyard grass of which the dormancy is broken away is cultured by the extract, the growth condition of the barnyard grass is observed, the sprouting percentage, root length and seedling length of the barnyard grass are measured, and the weed inhibiting performance is identified to screen the paddy rice with the high weed inhibiting function. The method has the characteristics of simplicity, quickness, accurate results and the like, and can be widely used for the auxiliary breeding of the weed inhibiting paddy rice.

Description

technical field [0001] The invention relates to a rice screening method, in particular to a rice laboratory rapid screening method with the function of inhibiting weeds. Background technique [0002] my country is the most populous country in the world and one of the major agricultural countries in the world. Rice is the most important food crop in my country. However, rice is often stressed by weeds during its growth and development, and the growth of weeds can cause the loss of more than 10% of the world's grains every year. Especially the ubiquitous problem of difficult weeding in direct-seeding rice has led to a large-scale production reduction of rice. There are two main ways to control rice weeds: one is to use chemical herbicides, which treat the symptoms but not the root cause, and cause serious pollution to the environment and rice; the other is to use the inhibitory effect of different rice materials on weeds to screen The new rice variety with significant weed ...
