The range of light adaptations can interact with higher crops. Yellow cabbage is the most common breeding method. When the harvest is over, the roots are dug, divided into a sprouts, the leaves around the troughs are removed, the roots are cut from top to bottom with a knife, each of them needs a stalk, and a stubble is needed below. Reproduction can be done by adhesion, with artificial pollination 10 to 60 minutes after flowering。
I. Cultivation of yellow cabbage
Yellow cabbage is thin and drought-resistant, and soil requirements are not stringent and can be cultivated at the geology and slopes. The range of light adaptations can interact with higher crops. The upper ground is cold and underground - 10°c. Avoid soil overwetting or water accumulation. The seedlings begin to excrete when the average temperature is 5°c or above, with a suitable temperature of 15-20°c for leaf blade growth and a high temperature required for flowering periods suitable for 20-25°c。
Ii. Cultivation of yellow flowers
1. Pre-cooked: the pre-cooked are the april flower, the may flower, the morning flower, the morning tea hill police。
2. Medium-preparatory type: precocious type: short arrow medium-term flower, tall arrow medium-term flower, porcelain flower, white flower, eggplant flower, small flower, long flower, black bush flower, etc。
3. Late-cooked: the late-cooked yellow bouquet consists of arrows, small leaves, mid-fall flowers, large leaves, etc。
Iii. The method of breeding yellow cabbage
Divisional: yellow cabbage is the most common breeding method. One is to excavate the whole of the herd and replant it separately, and the other is to extract some seedlings from the side of the herb and continue to grow. The seedlings and seedlings are collected as far as possible without causing any harm to the roots and are grown as soon as they are dug and distributed。
2. Slices: once the harvest has been completed, the roots will be dug and divided into sprouts, the leaves around the troughs will be removed, the leaves will die, leaves leaves leaves of leaves of 3-5 centimetres long, cut to the upper end, the roots will be cut from the top to the bottom in two pieces, each of them will be divided with a stalk, which will require a stubble, which will then be disinfected for 1,200 hours with more than 50% of the fungus。
3. Plug-in: after harvesting, the green of the pickles is selected from the flowers and above, the growth point below the blade is clear, leaving about 15 centimetres above and below each of the growth points, a little arc into the soil, burying the upper and lower ends in the soil, showing the parts of the blade with the growth point on the ground, slightly covering the protection of the fine earth, sprouts about a week later, one year of cultivation, 12 points per plant, at least 5, and the second year of flowering。
4. Seeding: the main bouquets have the highest rate of some branches and second branches, and the highest rate of first and second branches, so that the first to fourth branches can retain 1 to 4 bouquets and the top parts of the main bouquets can retain the first and second bouquets. The rest of the buds should be drained and the nutrients concentrated on fruit and seed grains。
