Geranium breeding technology

Radix is ​​a perennial herb that belongs to the Asteraceae soil. The southern region of China originates from tender young leaves and tender leaves, and has a high nutritional and health care effect. No pests have been found during its growth and it is a pollution-free vegetable. 1. The adventitious roots of the stem sections of the seedlings of M. violaceum are more prone to breeding. In the spring, 6 cm to 8 cm of apical buds are cut from a strong mother plant. If the apical buds are very long, they can be further cut into 1 to 2 segments with 3 to 5 leaves in each segment. The base 1 leaves ~ ~ 2 leaves, inserted in the seedbed, the bed available soil, or sand and straw ash, can also be inserted in the sink. Cuttings from 6 cm to 10 PCT, branches of about 2/3 of the soil, irrigated with water, covered with plastic film insulation moisturizing (keep 20 °C), often watered, survived for 10 ~ ~ 15 days, and then with soil transplant. In a frost-free place, the anniversary can be propagated, and in the north, the seedlings should be planted in a protected area. 2, the planting should choose a well-drained, organic-rich, strong water retention and fertility, good ventilation loam, soil is slightly acidic. 4.5 kg per square meter of cooked organic fertilizer is used as a base fertilizer, deep-turned, flat and flat. 3. The principle of field management irrigation is to see the soil dry and wet, and to pay attention to drainage and flood prevention in the rainy season. After the start of harvesting, 1 fertilizer is applied once per harvest. The manure urine 1.5 ton per gram of manure, or 15 to 22 grams of urea. 4. Picking and harvesting is slightly longer than 15 cm. The apex has five to six leaves. When harvesting, leave 2 to 3 leaves at the base of the stem to make newly emerged shoots slightly sickle. About half a month later, another harvest can be carried out. Only one section is left at the base of the stem from the second harvest so that the plant height and plant shape can be controlled. The southern region can be harvested on the anniversary, and greenhouse production in the northern region can be harvested on an annual basis. The harvest season is from August to September. 5. Prior to the initial frost preservation of the mother plant, select robust plants in the field, intercept the terminal buds, and cut them in the protected area, leaving the mother plant for use in the following year. The temperature in the protected area should be controlled above 5°C.
