Gypsophilapaniculata is also known as yuca grass and double wire carnation. Caryophyllaceae, Dianthus. Due to its small, light-colored, flowery fluffy three-dimensional character, elegant and elegant temperament, giving people a sense of ambiguity and excellent inflorescence groups, it is an important foiling flower and is one of the most popular cut flowers. It is very popular. .

Breeding method

In the case of Gypsophila cuts produced commercially, seedlings are propagated mainly in tissue culture, and they can also be propagated by cuttings. Some single-leaf species can be propagated by seeds.

1. Tissue culture was performed with shoot tip culture, with high propagation coefficient, good root growth, and good seedling quality. The tissue culture seedlings were used to produce cut flowers, the flowering branches were tall and straight, the color was pure, and the quality of cut flowers was high.

2. Cutting rooting rate is not too high, should use cuttings with 4 to 5 pairs of blades, with rooting powder or other auxin treatment cutting inserts in the perlite as a substrate bed, not subject to seasonal restrictions, but in late March to early July The best period is from late September to early November. When the temperature is above 15c, it usually takes 20 days for rooting.

Cultivation management

1. Before the planting, the soil should be deep-smeared with a depth of 40 cm to 50 cm. Apply enough organic fertilizer, and add some P and K fertilizers as appropriate. Acidic or neutral soil should be given some lime to adjust the pH of the soil. As a stilt, it is 30 centimeters to 40 centimeters high.

2. Colonization of 2000-2500 plants per acre (1 acre = 667 square meters), using double planting, spacing 50 cm, spacing 35 cm to 50 cm. Before planting, we must fill enough water, then choose cloudy days for planting, and plant water after irrigating. Planting time: As a cut flower cultivation, such as production in a greenhouse, it can be planted in summer or autumn or even early spring. In this way, flowers are collected in early autumn until early summer. Plants after flowering should be excavated from June to July, then refrigerated until August to September, and then planted.

3. The fertilizer and water management is full of starry fertilizers, but avoid water. After the planting, it is necessary to top-dress fertilizers in stages. Nitrogen is the main fertilizer in the early stage and phosphorus and potassium are the main components in the later stage. The moisture management must be strictly controlled, and the wet growth will weaken, and the water will cause the root rot to die. When the plant grows to 30 cm, it is necessary to control the watering, especially during the budding period, and the flowering period must be done. In rainy areas, shelter should be sheltered from rain.

4. Pests and diseases Stalk rot and dwarf diseases are fatal diseases of the gypsophila. Before the planting, the soil should be disinfected with formaldehyde solution. Insect pests are mainly fleas and aphids, which can be sprayed with 1000-fold solution of dicofol and 1500-fold solution of cypermethrin.

5. There are no fixed standards for cut flowers and cut flowers. The international market uses weight as the standard. Generally, it requires no less than 10 grams, and it also cuts at the base of the stem, taking the whole reproductive stem as a unit. The domestic market generally requires three branches per branch. The appropriate period for flower cutting is that 75% of the flowers are open. If the transportation distance is long, it can be appropriately advanced.
