High-yield and high-quality cultivation method of kale under plant factory conditions

Abstract

The invention belongs to the technical field of agricultural planting, and more specifically, the invention relates to a high-yield and high-quality cultivation method of kale under plant factory conditions. The high-yield and high-quality cultivation method of kale under the condition of a plant factory, the steps include: (1) Sowing: Soak the sponge block with clear water, and place the seeds of kale in the sponge block, pour clear water thereon, and then shade it. It is placed on the seedling rack in the nursery area to wait for the seeds to germinate; (2) seedling separation: remove the shading after the seeds germinate, and under the conditions of the plant factory, transfer the germinated seedlings together with the sponge block to the target buckle, and then put the buckle Put the plate in the nutrient solution seedbed to ensure that the roots are all immersed in the nutrient solution; (3) field planting: when the plants grow into 4-5 leaves after the seedlings are divided, all the plants in the pinch plate of the seedlings are transferred and planted (4) Harvesting: 20-25 days after planting, when the outer leaves of the plant have unfolded 10-12 leaves, the young leaves can be picked for consumption.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and more specifically, the invention relates to a high-yield and high-quality cultivation method of kale under plant factory conditions. Background technique [0002] With the improvement of people's living standards, the demand for high-quality vegetables is gradually increasing. Kale is one of the main vegetable varieties in my country. It is rich in nutrition, has extremely high health care functions and application value. Kale can be stir-fried, served cold, made into soup or pickled. It is tender in quality and crisp in flavor. It is a new type of health-care vegetable with high nutritional value. It provides essential nutrition for human health and is more and more popular in the Chinese market. . [0003] At present, the production of kale mainly depends on soil cultivation.

AI Technical Summary

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 leaves seriously restrict the improvement of yield and quality of kale

At the same time, there is a lack of relevant technical guidance and management experience in production and management, and the randomness is strong. Irrigation and fertilization are basically based on human experience and feelings, and the ratio of various nutrients is out of balance, resulting in a decrease in the production and quality of kale.
