Potted gypsophila paniculata doesn't need to be watered every day. It can be watered twice a day in summer when it is hot, and only once in winter when it is cold 10, but it should be watered when it is dry. Make sure the flowerpot is well drained.

2. Lighting equipment

Mantianxing is a plant that likes sunshine, so it should be kept in a sunny and ventilated place to maintain good air humidity and good lighting conditions, so that Mantianxing will bloom.

Step 3 trim properly

Usually, you can see that the sky is full of flowers, which is very lush. Because the gypsophila paniculata grows vigorously, it needs to be trimmed properly, and cut off at will where the leaves fall, and new branches and leaves will grow. The more you cut, the fuller it will become.

Step 4 apply fertilizer

Because the gypsophila paniculata grows fast and consumes nutrients quickly, it needs fertilization to supplement nutrition. As for fertilizer, compound fertilizer and nutrient solution can be used. We should also pay attention to the principle of applying a little more fertilizer, which is basically applied once every 7- 10, and watered after fertilization.

5. Turn over the pots and change the soil

Mantianxing will grow normally under normal care, but the soil should be changed according to a certain time rule, so the soil should be turned once every 1-2 years. Of course, the most reasonable time is February-March or late autumn, properly pruning the roots, and then turning over all the old and new soil.

Extended data:

Produced by commercial cut flowers from all over the sky, seedling propagation is mainly based on tissue culture, and can also be propagated by cutting, and some single-petaled species can be propagated by seeds.

1. Tissue culture

Shoot tip culture has high propagation coefficient, good root growth and good seedling quality. Cut flowers produced by tissue culture seedlings have straight branches, pure color and high quality.

Step 2 cut

The rooting rate is not too high, so we should choose 4-5 pairs of leaves for cutting on perlite bed after being treated with rooting powder or other auxins, which is not limited by seasons, but the best period is from mid-late March to early July, and from late September to165438+1early October. When the temperature is above 15C, roots can generally grow within 20 days.

Carry out soil preparation

Before planting, the soil should be deeply turned 40 cm ~ 50 cm, and sufficient organic fertilizer should be applied, and some phosphorus and potassium fertilizers should be applied appropriately. Acidic or neutral soil should be properly applied with some lime to adjust the pH value of the soil. As the high side, the side surface is 30 cm ~ 40 cm high.

Field planting

Plant 2000 ~ 2500 plants per mu (1 mu =667 square meters), with a row spacing of 50 cm and a spacing of 35 cm ~ 50 cm. Fill enough water before planting, then choose cloudy days to plant, and then water after planting. Planting time: as a cut flower cultivation, it can be planted in summer or autumn or even early spring if it is produced in greenhouse. In this way, flowers have been picked from early autumn to early summer. After picking flowers, the plants should be dug out in June-July, then refrigerated until August-September, and then planted.

Fertilizer and water management

All over the sky, stars like fat and avoid water. After planting, topdressing should be carried out in stages, with nitrogen fertilizer as the main fertilizer in the early stage and phosphorus and potassium fertilizer as the main fertilizer in the later stage. Water management should be strictly controlled, too wet and too weak, and stagnant water will cause root rot and death. When the plant grows to 30 cm, water should be controlled, especially in bud stage, and it should be kept dry in flowering stage. Cultivation in rainy areas should be sheltered from rain.

Eliminate pests and diseases

Stem rot and atrophy are fatal diseases of gypsophila paniculata, and the soil should be disinfected with formaldehyde solution before planting. Pests are mainly mites and aphids, and dicofol 1000 times and pyrethroid 1500 times can be sprayed.

Cut flowers and listing

There is no fixed standard for the cutting of gypsophila paniculata. In the international market, weight is the standard. Generally, one branch is required to be no less than 10g, and it is also cut at the base of the stem, taking the whole reproductive stem as the unit. The domestic market generally requires three branches. The suitable time for cut flowers is that 75% of the flowers are open. If the transportation distance is long, it can be advanced appropriately.
