Embodiment 1

[0026] A cultivation method for alleviating cabbage stalk downy mildew and anthracnose, comprising the following steps:

[0027] (1) Seed disinfection: After the seeds are fully dried, they are placed in a 50°C incubator, and the thickness of the tiles does not exceed 2cm. Dry heat disinfection for 10 hours, take out and cool down for sowing;

[0028] (2) Seedling cultivation in plug trays: soak the plug trays in 1% lime water for disinfection for 10 hours, take them out and put them into the cabbage sprout seedling substrate after drying, then sow the sterilized seeds, and sow 1 seed in each hole; the composition of the cabbage sprout seedling cultivation substrate includes peat , rice husk ash, tea dry cake, bio-organic fertilizer and superphosphate, fully mixed at a volume ratio of 5:3:0.5:1:0.5;

[0029] (3) Management at the seedling stage: when the seedlings reach the 2-3 leaf stage and the 4-leaf stage, spray the disease-controlling liquid No. 1 once, and the interval b...

Abstract

The invention belongs to the technical field of vegetable cultivation and particularly relates to a cultivation method for relieving downy mildew and anthracnose of flowering cabbages. The method comprises the following steps: (1) seed disinfection; (2) plug seedling raising; (3) management of a seedling period; (4) soil preparation and transplantation; (5) regulation and control of growth; and (6) timely harvesting. The method improves disinfection and seedling raising methods, a self-made formula of a flowering cabbage seedling raising substrate in the plug seedling raising is used, a bio-organic fertilizer and calcium superphosphate are organically combined as a field base fertilizer, and meanwhile, a self-prepared disease control solution I and a self-prepared disease control solution II are applied. The method has a downy mildew control effect of flowering cabbages about 82% and an anthracnose control effect about 85%. Besides, an orchard storage life is long, a flowering cabbage picking period is long, the yield is increased by 16.2-18.3%, and an average yield is increased by about 17%. Meanwhile, the method has characteristics of easy material obtaining, simple and convenient operation, is green and environmentally friendly, and has a high yield of flowering cabbages, particularly obvious economic benefits and a very wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a cultivation method for alleviating downy mildew and anthracnose of cabbage stalks. Background technique [0002] Cabbage stalk is a variety of Brassica genus pakchoi subspecies, which is mainly used for food. It is favored by consumers because of its unique flavor, and it is one of the important vegetable varieties in winter and spring. Downy mildew and anthracnose are the main diseases during the growth of cabbage sprouts. The downy mildew survives the winter with the diseased residues in the soil or on the roots of cruciferous vegetables or winter storage plants, and sometimes it can be mixed in the seeds and survive the summer or winter. Wetness can easily lead to disease epidemics. The anthracnose fungus survives the winter as mycelium on diseased residues and seeds, and spreads through wind and rain. High temperature and high humidity are import...
