Cultivation method of broccoli

Abstract

The invention belongs to the technical field of plant cultivation, and relates to a plant cultivation method, in particular to a cultivation method of broccoli. According to the greenhouse broccoli high-yield and high-efficiency cultivation technology, the disease resistant, medium-maturing and late-maturing broccoli with the long picking time is selected, seeds are sown, germination acceleration and poikilothermic treatment are carried out on the seeds, main root tips are cut off, growth of lateral roots are facilitated, and the seeds are cultivated in an open-mouthed rectangular container; meanwhile, by means of a nutrient solution, the seedling stage quality is good, the leaf color is dark green, the sound seedling index reaches more than 99%, planting is carried out when the seedling age is about 30 days, the seedling slowing time is short, the growth is fast, the ultimate capacity is high, the quality is good, the temperature inside a greenhouse can be adjusted by opening or closing large and small greenhouse thin films from the initial budding stage to the harvesting process of the broccoli particularly in autumn and winter which are low-temperature seasons, higher economic benefits can be obtained after the broccoli appears on the market before or after a festival, meanwhile, the quality of the broccoli is improved, the yield per mu can reach more than a ten thousand yuan, and the standardized pollution-free greenhouse cultivation is achieved.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a broccoli cultivation method, and belongs to the technical field of plant cultivation. Background technique [0002] Broccoli (Broccoli), also known as green cauliflower and broccoli, is a variety of Brassica Brassica Brassica species with green curds and fat and tender flower stems as products. Broccoli is rich in nutrition and has a good flavor. After cooking, the green color remains unchanged, and it is fragrant and tender. It is suitable for boiling, frying, cold dressing, and freezing. Studies in Europe and the United States believe that broccoli contains anti-cancer substances, and regular consumption can prevent cancer and reduce the incidence of cancer. It is known as a high-end health vegetable and has been selling well. With the improvement of people's living standards, the awareness of nutrition and health care is constantly increasing, and broccoli is gradually recogniz...

AI Technical Summary

Problems solved by technology

Existing cultivation methods are open-field seedling cultivation and plug seedling cultivation. The open-field seedling cultivation is extensive, management is difficult, soil-borne diseases are difficult to control, the amount of seeds used is large, and the size of seedlings is obvious. Mutual isolation, few diseases, not easy to infect each other, the nutrient soil in the hole of the hole is loose, which is conducive to the downward growth of the main root, and the fibrous root is relatively weak, which is not conducive to the cultivation of strong seedlings, etc.

Because the seedlings of broccoli are tap roots and have few fibrous roots, it is not conducive to the absorption of nutrients and water by the roots. After transplanting and planting, the growth is slow, and they are not resistant to waterlogging and root diseases. The yield is low and the benefit is poor.
