The cabbage, the ancient ravioli, with the points of large whiteblades and cabbage, which are the fruit and specialty of our country, is one of the most important vegetables that people often eat. The site of the simpo village during the neostone period had earthed cabbage seeds. It is clear that the vegetable cultivation is now about 670 years old. Let's talk about cabbage today
I. Holding and holding
Since cabbage is very easily grown on a continuous basis, it should be rotated, preferably between daejeon crops and vegetables, and not with other cross-flower vegetables, such as bean horns, peppers and cucumbers. The field of large cabbage is grown for 10 to 15 days at a depth of 20 to 27 centimetres, and the land is then crushed to a level of 1. 3 to 1. 7 metres wide or 0. 8 metres narrow and high. When doing this, it is required to open deep trenches, gutters and gutters of more than 27 centimetres in order to connect them。
Ii. Solution methodology
In addition to the direct planting of vegetable seedlings in the early spring, summer, etc., the best alternative would be to use water-conserving, well-drained land as a nursery field and then clean up the collected gardens, level up the highlands and dry up. Seeding can be done in a balanced or diluted manner, with attention to disease- and pest-friendly prevention and treatment, timely fatting and watering. In general, 25-30 days after planting, it is possible to replant early autumn and late autumn, which can increase the resistance of cabbage to freezing。
Iii. Fertilizer management
The cabbage is small and has a weak absorptive capacity and should be constantly fed during its growth. Repeated pursuit of fast-acting nitrogen fertilizer is an important measure to promote cabbage growth and ensure productivity. (a) the principle of rational fertilization: first, the timely pursuit of fatting after planting and the promotion of the recovery of seedlings; the second is to grow with cabbage and increase the concentration and use of fertilizer. For fertilisation methods, periods, usages, etc., depend on weather, seedling, soil etc. Water is being poured in conjunction with fat pursuit. Water must not be scarce for three to five days after planting, especially in summer and early autumn, and must be watered every morning and night for three to four consecutive days. In order to grow cabbage, organic fertilizers should be used as base fertilizers, with proper follow-up of fertilizer during growth, as well as a combination of spraying, which can also be used for leaf fertilizing。
Iv. Pest management
In the case of large cabbage, which is often found in “black spots”, a black molded object, which can be transmitted by air currents to harm other large cabbages, or by links between leaves, can cause the death of the cabbage leaves from internal and external decay, causing considerable economic loss, and can be attached to large cabbage seeds, which directly endanger young seedlings, so that 50 per cent of the plumes with seed weights of 0. 2 to 0. 3 per cent are sown with wettable powder. If a hazard occurs during growth
The effects can be observed two to four times with 75 per cent of the 100 microbacterium clean humid powder 600 times more liquid, or 50 per cent of the humid powder 1,500 times more liquid, in combination with the aprilo orange oil aid. There is also a need to control the humidity of the field, to provide ventilation in the field and to avoid the accumulation of water in the field。
Caution: 1 disease-prone plot. The land that is sown without seed treatment, with cross-facility and adjacent areas, is planted prematurely, with a high density of fields, low-fat and low-fat land, with a large and weak field, with a heavy water flow and prone to disease. 2 vulnerable vegetables. In addition to cabbage, cabbage, ganland, oils (colour or cabbage) and broccoli (creas) are vulnerable to the disease, so be careful。
