High-yield and high-quality cultivating method for brassica oleracea var.acephala in plant factory condition

Abstract

The invention belongs to the technical field of agricultural planting and particularly relates to a high-yield and high-quality cultivating method for brassica oleracea var.acephala in a plant factorycondition. The high-yield and high-quality cultivating method for the brassica oleracea var.acephala in the plant factory condition comprises the steps of (1) sowing: saturating a sponge block with clear water once, sowing seeds of the brassica oleracea var.acephala into the sponge block, irrigating the sponge block with the clear water, carrying out shading, and putting the sponge block on a seedling frame of a seedling area for seed sprouting; (2) seedlings separation: removing a shade after the seeds sprout, transferring the seedlings after sprouting together with the sponge block into a target pinch plate in the plant factory condition and then putting the pinch plate into a nutrient solution seedbed to ensure that all roots are immersed into a nutrient solution; (3) permanent planting: when each plant has 4-5 leaves after seedlings separation, transferring and permanently planting all plants in the pinch plate in first seedling separation into the other pinch plate and putting the other pinch plate into the nutrient solution seedbed; and (4) harvesting: when each plant expands 10-12 outer leaves in 20-25 days after permanent planting, picking tender leaves for eating.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and more particularly, the invention relates to a high-yield and high-quality cultivation method for kale under plant factory conditions. Background technique [0002] With the improvement of people's living standards, the demand for high-quality vegetables is also gradually increasing. Kale is one of the main vegetable varieties in my country, which is rich in nutrients and has extremely high health functions and application value. Kale can be fried, salad, soup or pickled, tender in quality and crisp in flavor. It is a new type of health-care vegetable with high nutritional value, providing essential nutrition for human health. It is more and more popular in the Chinese market. . [0003] At present, the production of kale mainly relies on soil cultivation. The traditional solar greenhouse is greatly affected by the external natural environment conditions, such as insufficient li...

Problems solved by technology

[0003] At present, the production of kale mainly depends on soil cultivation. Because the traditional solar greenhouse is greatly affected by the external natural environmental conditions, such as insufficient light, high temperature and other natural factors, resulting in long growth cycle of kale, serious pests and diseases, accumulation of nitrate and Premature senescence of plants and yellowing of lower leav
