Asparagus cold frame seedling raising method

Abstract

The invention discloses an asparagus cold frame seedling raising method comprising the following steps: (1) seed treatment: soaking asparagus seeds in 75% chlorothalonil wettable powder for 12h, then rinsing the asparagus seeds with water, soaking the asparagus seeds in warm water for 24h at 25 DEG C, changing the water for twice within one day, and scrubbing the seeds when changing the water to remove abortive seeds and impurities; (2) seed germination: wrapping the soaked seed with damp cloth, and germinating the seeds in an environment of 25 DEG C; (3) bedding and sowing: controlling the border width to be appropriately 1.5m, scattering 5kg high-quality decomposedmanure and 25kg ternary compound fertilizer in the compost of each square meter, coating films before sowing, and dibbling a single seed according to a seed spacing of 5cm*5cm; and (4) daily fertilization: spraying equal mass of monopotassium phosphate and urea, preparing the same into a solution with a concentration of 1%, and spraying the solution onto the compost after each half a month in a dosage of 8g / m<2>, until the seedling raising is completed. The asparagus cold frame seedling raising method disclosed by the invention has advantages of low cost and high survival rate.

Description

technical field [0001] The invention relates to a method for raising asparagus seedlings in the sun border, which is applied in the technical field of asparagus seedling raising.

Problems solved by technology

[0003] Asparagus is different from other vegetables. It is a perennial plant. It can be harvested continuously for 15 years after one planting. Therefore, the cultivation of asparagus is particularly critical. Most of the asparagus cultivation methods on the market are relatively traditional, and the survival rate is low; High, heavy burden for some small growers
