Cabbage Seedling Technology
Spring cabbage is one of the spring vegetable varieties. Due to constant expansion of planting area throughout the year, its planting technology has also been greatly improved. However, despite many years of trials and continual summaries in the technical aspects, farmer management patterns such as fertilization, nursery, and There are still large differences in the prevention of convulsions. In order to further optimize spring Cabbage fertilization techniques, the microbial microbiology experts (see details) click here for details:
Seedlings are the first step in growing vegetables and are related to the success or failure of the entire vegetable production process. Winter and spring cabbage cultivation mostly uses seedlings for nutrition. This method has the disadvantages of nutrient soil bacteria, poor quality of seedlings, and the like. If it encounters bad weather, it can easily cause a large number of seedlings to die. This aspect has led to a delay in the entire production season, which has led to a drop in the efficiency of vegetable production. On the other hand, the entire production cost has greatly increased.
In this paper, we use the technique of seedlings for seedlings. Winter and spring seedlings must be grown in plastic greenhouses or in multi-span greenhouses. If you use old plugs, clean, rinse, and disinfect the plugs. Commercially available substrate soils (higher cost) can also be used, as can seedlings. The production of raw materials for the production of vegetables using commercially available starters such as Ginba base earth leaven, which will save a lot of money for the farmers, such as only one kilogram when using substrate soil starter to produce vegetable seedlings with substrate soil. The starter can complete the fermentation of nearly five tons of raw materials. In addition, the raw materials for fermentation can be easily obtained. The farmers can make full use of the leftover materials (such as wheat straw and corn stalks) and the organic waste in the fields to complete the production of production materials. The same method is also applicable to the production of farm organic fertilizer, which not only saves production costs, but also reduces the amount of fertilizer used. The prepared matrix and decomposed organic fertilizer and compound fertilizer are mixed in a certain proportion. In addition, in order to prevent fungal contamination, 50% carbendazim WP and 150 g thiophanate-methyl wettable powder can be added to each cubic metre of nutrient soil. The moisture content of the matrix must reach the state of being held in a clump and loosening. Also available from the substrate production plant.2. Cabbage Substrate Plug Seed Seed Treatment Put the seeds in warm water at 50°C and keep stirring for 15 minutes until the water temperature drops to 30°C and stop stirring. Or soak with potassium permanganate 1000 solution for 20 minutes, then rinse with water. The sterilized seeds were soaked and germinated, and the germination temperature was controlled at 28-30°C.
3. Cabbage substrate seedling nursery management Spring seedlings should increase light intensity and light hours as much as possible. Winter and spring seedling film nets should be covered as soon as possible, and should be opened on rainy days to increase lighting in the shed. Can also be equipped with incandescent lamps to supplement the light, summer and autumn seedlings can increase ventilation to regulate seedling growth. Covering insect nets in the air outlet can be effective to prevent pest intrusion and reduce the risk of infectious diseases such as locusts. , Before the true leaves have been sent out, the water is moderately controlled. After the true leaves are sent out, the principle of watering is not to be poured. The seedling stage diseases mainly include damping-off disease and downy mildew. Physical methods such as yellow plate trapping and killing of aphids are preferred. Etc. Can also be combined with imidacloprid, cypermethrin and other chemical methods.
4. Prevention of bolting in cabbage cultivation In spring cabbage cultivation, early bolting often occurs, which seriously affects product quality and yield. Can choose to pull the low rate of early maturing varieties, appropriate sowing, cultivation of strong seedlings and other methods.
