Choose a variety
To grow the broccoli better, the choice is first to choose the species, usually according to its maturity, which can be divided into three types of early and late ripening. The selection of varieties can be based on different planting seasons. If cultivation takes place in the summer and autumn, it should be based on heat-resistant and more mature varieties, if it takes place in winter, on cold-resistant varieties, and its strains are compact, flowery medium or early。
Planting seedlings
If you choose to plant broccoli in winter, you have to choose its wider applicability, and its more cold-resistant varieties, before seeding, the ready bed can also be grown in a trophic strain. Soils should preferably be selected from soils that have not grown cross-flower vegetables within three years. It is then necessary to apply enough organic fertilizers to the land, mix them with the soil, then level the ground, and if the temperature is high and the extra season is covered by a sunnet that prevents not only strong light but also rain。
The whole place
Land selection should be based on higher terrain, better drainage, better ventilation and light, and soil fertilization. Following the harvest of the former crops, it is important that some of the residuals be cleared in a timely manner, that the land be tilled and tan, that sufficient fertilizer be applied to each acre, and that sufficient organic compound fertilizer be applied to each acre, and that octhion granules be added before the land is mixed with the soil, which is then flatted。
Shrimp management
Before planting the seeds, new, high-fat membranes should be used to mix the seeds, so that they can be effectively removed from the ground, as well as to isolate the virus infection and enhance the breathing of the seeds, so that they can be effectively increased in their growth rate. Sufficient drops of water must be delivered before planting, and then the seeds must be spread evenly in the seed bed, after they have been properly planted, with a layer of about 1. 5 centimetres of trophic soil over the seeds, which can then be sprayed with some new high-fat membrane 800-fold fluid for temperature protection and can effectively promote seedling。
Plantation
When selecting a fixed value, it is important to choose the border or sandy soil that is relatively fertile, and to apply sufficient organic and compound fertilizers in the field, and then to have full tillage, with proper planting, and with sufficient electricity and water at the same time as planting, to be watered every other day, and to spray new high-fat membranes with 800 times more liquid, so that the infection of some bacteria can be effectively prevented, not only to increase the resistance of young seedlings, but also to reduce the duration of his plant。
Field management
When the plant has been replanted, it can be restored to normal development, so it is important at this stage to have a meadow and to combine it, so that its roots can be effectively prevented from being exposed outside, and then some fertilizer can be sprayed in a timely manner, the seedling can grow stronger and, in the case of the buds, the sprouts can be sprayed in a timely manner. That would make his feelings stronger and her balls more fatter, while improving her resilience。
Pest control
Throughout its growth, some pests and pests must be dealt with in a timely manner, and in the long-term lifetime of the groundnuts are prone to the occurrence of certain pests, such as froste, softosis, vegetable geisha and moths, which require the use of targeted medicines, such as the hysterics humid powder, and thionphos-methyl cream, which can be extinguished and which can be effectively prevented if some of the targeted drugs can be sprayed。
