Float seedling method for globe artichoke

Abstract

The invention discloses a float seedling method for globe artichoke. The method specifically comprises the following steps: selecting a seedling field; constructing a greenhouse; constructing a seedling pond; selecting and disinfecting a seedling raising tray; selecting a substrate; raising seedlings; performing seedbed management; preventing and controlling diseases, and the like. The method has the beneficial effects that 1, the emergence rate is high, the emergence rate of the technology can reach 96 percent, but the emergence rate of a nutrition pot technology is 75 percent; 2, the full stand time for one sowing period is shortened and can be shortened by 5 days compared with other seedling raising methods; 3, the seedling raising quality is good, the globe artichoke seedlings cultivated by measures such as nutrition control, seedling cutting and sterile culture are tidy, uniform, robust, developed in root systems and disease-free, the field diseases can be effectively reduced, particularly the occurrence of the empty stem withering diseases is reduced, the investment and the labor for globe artichoke farmers can also be reduced, and the yield and the quality of the globe artichoke are improved; 4, the transplanting is convenient, and the seedling raising trays are extremely convenient to handle because of the light weight of the substrate; 5, the cost is reduced, the cost of a single seedling obtained by the method is 0.5 yuan, but the cost of the single seedling obtained by the nutrition pot technology is 0.7 yuan.

Description

technical field [0001] The invention relates to the technical field of artichoke cultivation, in particular to a method for raising artichoke seedlings by floating. Background technique [0002] Artichoke is a perennial herbaceous perennial plant in the Asteraceae family, native to the Mediterranean coast. Under natural conditions, a local artichoke can live for more than ten years. In terms of production, local farmers generally update every 3 to 5 years. In my country, artichokes are mostly cultivated as annuals, and most of them use seeds to raise seedlings. Due to the climate, artichokes can bloom but not bear fruit in our country. All the seeds need to be imported every year, which is expensive and the cost of raising seedlings is high. Artichoke seeds are achenes with thick and hard seed coats, making it difficult to raise seedlings. This just makes artichoke seedling raising technology become a bottleneck problem of this industry development. [0003] The reasons...

AI Technical Summary

Problems solved by technology

[0006] ② Low germination rate: Because of the thick and hard seed coat and poor water absorption capacity, it is difficult for seeds to germinate

[0007] After budding, it will affect its vitality

[0008] ③ Irregular emergence: it only takes 7 days for the earliest seedlings to emerge, and 25 days for the late ones, with a large difference between before and after

[0009] ④ Low survival rate of transplanting: the leaves of thistle seedlings are relatively large, easy to lose water, and the survival rate of transplanting is low

The nutrient bowl is heavy and inconvenient for transplanting

When the nutrient pot is transplanted, the tap root and more roots are cut off, so that the artichoke is artificially changed from a tap root crop to a fibrous root crop, which affects root development and plant growth
