Method for improving seed production yield of common head cabbage sterile line

Abstract

The invention relates to a method for improving the seed production yield of a plant, particularly relates to a method for improving the seed production yield of a common head cabbage sterile line, and belongs to the technical field of plant cultivation. According to the method, seed sprouting and poikilothermic treatment are adopted, and the root tips of main roots are cut off; tray-soilless seedling is also adopted, an open rectangular container is used for cultivation and water storage, and the moisture of a substrate is adjusted to keep the substrate wet, so that the mode is more uniform and practical compared with water spraying, and water is not gathered on the surface of a plant; meanwhile, by virtue of the cooperative use of a nutrient solution, healthy growth of seedlings is promoted, and the seedlings are full and strong, so that sowed common head cabbage seedlings have short main roots and a large number of fibrous roots, have a high survival speed after being transplanted, grow well, and are high in disease resistance and high in stress resistance; by virtue of scientific large-field management, parent flower section regulation, parent interaction plantation and density regulation, the seed production yield of the common head cabbage sterile line can be improved by about 35 percent compared with the prior art. The method is easy to operate, short in time, high in efficiency, and more standard and more scientific in operation. Thus, the method has a popularization value in production definitely.

Description

technical field [0001] The invention relates to a method for increasing the yield of plant seed production, in particular to a method for improving the yield of sterile line of cabbage seed production, and belongs to the technical field of plant cultivation. Background technique [0002] Heading cabbage (Brassica oleacea L.var.cap itata L.) is a variety of Brassica plants in the family Brassicaceae, also known as cabbage, cabbage, cabbage, lotus white, etc. It originated from the Mediterranean coast and began to be introduced in the 16th century. China. Heading cabbage has the characteristics of cold resistance, disease resistance, strong adaptability, easy storage and transportation, high yield, and good quality. It has become a vegetable cultivated worldwide and is widely cultivated in various parts of my country. One of the main vegetables in summer and autumn, due to its wide adaptability, strong stress resistance, stable yield, and resistance to storage and transportati...

Problems solved by technology

Existing cultivation methods are open-field seedling cultivation and plug seedling cultivation. The open-field seedling cultivation is extensive, management is difficult, soil-borne diseases are difficult to control, the amount of seeds used is large, and the size of seedlings is obvious. Mutual isolation, few diseases, not easy to infect each other, the nutrient soil in the hole of the hole is loose, which is conducive to the downward growth of the main root, and the fibrous root is relatively weak, which is not conducive to the cultivation of strong seedlings, etc.

Since the seedlings of head cabbage are taprooted and have few fibrous roots, it is not conducive to the absorption of nutrients and water by the roots. After transplanting and planting, the growth is slow, and they are not resistant to waterlogging and root diseases. The yield of seed production is low and the benefit is poor.
