Seedling raising method for broccoli strong seedlings

Abstract

The invention relates to a seedling raising method for vegetable strong seedlings, in particular to a seedling raising method for broccoli strong seedlings, and belongs to the technical field of plant cultivation. On the basis of the prior art, through pre-sowing and a method for spraying a special fertilizer for seedling raising in the seedling stage, the potted tray seedling rate is greatly increased, the growth vigor consistency of seedlings planted in the same stage is ensured and strong seedlings which are healthy in growth and have stubby stem nodes, deeper green leaves and developed roots can be raised.

Description

technical field [0001] The invention relates to a method for growing strong seedlings of vegetables, in particular to a method for growing strong seedlings of broccoli, belonging to the technical field of plant cultivation. Background technique [0002] Broccoli (B rassica oleracea L.var.italica), also known as broccoli, green cauliflower, stem broccoli, etc., is a primary or secondary herbaceous plant with green curds as product organs in Brassicaceae Brassica species. Its product is the green flower ball formed on the top of the main stem and side branches. It is rich in nutrition, good in color, aroma and taste, and is a famous and special vegetable that is very popular in the international market. The cultivation history of broccoli in our country is not long, but it has developed rapidly, especially with the improvement of people's living standards and the understanding of the nutritional value and health effects of broccoli, the demand for broccoli will inevitably doub...

AI Technical Summary

Problems solved by technology

Although people have researched and summarized a relatively complete technical system in the cultivation of broccoli plug-in substrates, due to the influence of factors such as temperature, moisture, seed germination rate, and germination potential, it is not only impossible to guarantee that there will be a seedling in each hole, but also because the seeds emerge. The number of days is different, and the number of days for seedlings in the same plug sown in the same period will also differ by a few days, resulting in the competition and inhibition of the first seedlings and the second seedlings in space, light, etc., resulting in different plant sizes during planting. The quality is also uneven

More importantly, although broccoli seedlings have little total demand for nutrients in the seedling cultivation stage, they are very sensitive. Insufficient or unbalanced nutrient supply will result in weak seedlings, which will eventually affect subsequent plant growth, yield and quality. Therefore, how to cultivate consistent growth vigor Strong seedlings have always been a difficult point in broccoli seedling cultivation
