Method of cultivating early-maturing common head cabbage strong seedlings

Abstract

The invention relates to a cultivating method of vegetable, in particular to a method of cultivating early-maturing common head cabbage strong seedlings, and belongs to the technical field of vegetable cultivation. In a seedling growing phase, a potted tray is utilized to be combined with a greenhouse, nutrition, temperature, water and light environment conditions which are needed by common head cabbage seedling growth are better provided, harmful influences on the seedling growing process caused by severe changes of environment conditions are avoided, and normal growth of the common head cabbage seedlings is guaranteed. By germinating seeds, cutting main root tips, managing and cultivating strong seedlings scientifically, the common head cabbage seedlings after seeding are short in main roots, multiple in fibrous roots, fast in survival after transplanting and field planting, good in growing trends and strong in disease resistance, and yield is improved by about 15%.

Description

technical field [0001] The invention relates to a method for cultivating vegetables, in particular to a method for cultivating robust seedlings of head cabbage, and belongs to the technical field of vegetable 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 transportation, its cultivation has developed rap...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic cabbage seeds are mostly imported from abroad, and the seeds are expensive. The direct impact of seedling failure or uneven quality of finished products is economic loss.

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 have tap roots and few fibrous roots, it is not conducive to the absorption of nutrients and water by the roots. After transplanting and planting, they grow slowly, are not resistant to waterlogging and root diseases, and have low yields.
