Cotton indoor cultivation method and application thereof

Abstract

The invention provides a cotton indoor cultivation method and applications thereof and relates to the technical field of cotton cultivation. The cotton indoor cultivation method includes the followingsteps of sowing sterilized coated cotton seeds into the substrate, thinning out seedlings after the cotyledons of the coated cotton seeds are unfolded, and coating the substrate with a layer of the substrate when the fourth true leaf of cotton unfolds. The cotton indoor cultivation method has the advantages of effectively promoting the production of adventitious roots of the cotton, allowing theroot fresh weight of the cotton seedlings planted by the above-mentioned method to increase by 12.4% and the total fresh weight to increase by 6.1% compared with the cotton grown by the control method, allowing the number of the adventitious roots to be significantly higher than those planted by the control method, thus not only promoting adventitious root formation in cotton plants, but also effectively simulating field soil cultivation, and being capable of being vigorously promoted in the study on root development of cotton in indoor potted plants.

Description

technical field [0001] The invention belongs to the technical field of cotton cultivation, and in particular relates to a cotton indoor cultivation method and application thereof. Background technique [0002] There are two types of roots in plants, one is the embryonic root derived from the embryo, which is the basis for the plant to form a strong root system; the other is the Adventitious root, which does not occur in the normal sequence and appears in an abnormal position (such as stems, leaves). In most cases, the occurrence of adventitious roots is due to the stimulation of plant organs by external factors such as hormones, pathogenic microorganisms, and abiotic stresses, and thus manifests as a regenerative response of plants. The formation of adventitious roots is an active adaptation method for many plants to resist waterlogging stress, and it is of great significance for plants to adapt to waterlogging stress. However, the cotton root system is a tap root system, ...

AI Technical Summary

Problems solved by technology

However, the cotton root system is a tap root system, which has the characteristics of underdeveloped aerenchyma, weak absorption, and weak regeneration ability. Before flooding stress, the cells of cotton hypocotyls or stems are not specifically used to form adventitious roots, resulting in the formation of adventitious roots. The Main Ways of Cotton Adapting to Flooding Stress

[0003] In the practice of field production, the temperature and moisture of the plant growth environment are difficult to control accurately, and the root system samples of the plants cannot be completely obtained, so it is difficult to conduct research on the growth and development of adventitious roots

In field cotton planting and production, it is difficult to obtain a complete root sample from the soil, so the effect of cultivating soil to induce adventitious roots through field experiments is extremely limited

However, traditional indoor potting uses materials such as flower pots, cultivation soil, or substrates. The main purpose is to obtain cotton seedlings, which cannot effectively induce cotton plants to produce adventitious roots. Therefore, it is impossible to study the occurrence and effect of cotton adventitious roots.

[0004] At present, there is no simpler and more effective cotton cultivation method that can be used to study the occurrence of adventitious roots in cotton
