The latest Culture method of Chrysanthemum morifolium

Melon, also known as rich chrysanthemum, cucumber flower, etc., is a perennial herb belonging to the genus Melon of Compositae. It is often cultivated for 1~2 years. It is divided into high-growth species and dwarf species. The flower language is joy, joy, happiness, family joy and prosperity. It is suitable for giving to relatives and friends during the Spring Festival. The color is bright and reflects the good intention. Let's take a look at the breeding method of Melon!

The growing habits of melon

Melons like warm, humid and well-ventilated environments. Not resistant to high temperatures, afraid of frost. Generally, it is cultivated in low temperature greenhouse, the temperature is not lower than 5℃ at night, but the seedlings can also withstand the low temperature of 1℃, and the daytime is not more than 20℃, and the most suitable temperature is 10~15℃. Room temperature is too high easy to grow, resulting in internode elongation, lack of commodity value. The temperature is too low, affecting plant growth, flower development small. Because the leaves of melon are large and thin, it is necessary to keep sufficient water, but it cannot be too wet, so it is appropriate to keep the leaves from wilting.

Breeding method of melon

Melon is generally propagated by sowing, lightly sown in pots in August, kept at 20~25℃, germinated in 10~20 days, and it takes 6 months from sowing to flowering. After sowing, the seed box should be placed under the shade, or under the shade. If the seed is planted in a row, then the shade must be set up above the wow soil to reduce the radiant heat of the sun. Double-petal varieties to cutting-based, in the upper part of the plant cut off, take the stem germination of strong branches, in coarse sand cuttage.

Culture method of melon

1. Soil: Melon is native to the Atlantic Canary Islands. It is widely cultivated in parks or courtyards all over China. It likes sandy loam rich in humus and good drainage. It is suitable for neutral and slightly acidic soil.

2, sunshine: melon in the growth period like sunshine, not shade. To rotate the flowerpot regularly, so that the branches and leaves receive light evenly, and the plant shape is correct and not skewed. After flower withers, plants still need moderate light to adapt to seed development.

3, watering: melon leaves are large and thin, need to maintain sufficient water, but can not make the pot soil too wet, in order to maintain the leaves do not wither as appropriate. Usually watering should be determined according to the dry and wet conditions of the basin soil. After drying, irrigate it again. It takes about 2 to 3 days to irrigate once. Water can be sprayed on the leaves once a day. In hot weather, water can be sprayed twice to reduce the temperature and increase the air humidity. After the bud appears, it should be watered as much as possible, and the pot should be placed in a cool environment of 8~12℃ during flowering, which can extend the flowering period to 30~40 days.

4, temperature: melons like warm and not resistant to high temperature, in the conditions of 15~20℃ growth best. When the temperature is higher than 21 ℃, the phenomenon of excessive growth can occur, which is not conducive to the formation of flower buds. When the temperature is lower than 5℃, the plant stops growing and developing, when the temperature is lower than 0℃, the plant will be frozen, the suitable temperature for flowering is 10~15℃, when the temperature is lower than 6℃, the flower can not be opened, and when the temperature is higher than 18℃, the flower stem will grow slender and affect the ornamental value.

5. Fertilization: In addition to applying base fertilizer when planting, thin cake fertilizer should be applied every 7~10 days during the growth process, and diluted chemical fertilizer can also be used. After flower buds appear, potassium dihydrogen phosphate 1000 times solution can be added 1~2 times, and fertilization continues until flowering (stop in rainy season). When fertilizing, such as contaminated leaves should be washed in time.

6, pests: melon common insect diseases are aphids and red spiders, for aphids and red spiders more serious harm, available 2000 times dimethoate diluent spray kill. Because red spiders generally occur on the back of the leaves, and aphids generally occur on the top of the tender melon, spraying should focus on the back of the leaves and the top of the plant, and the front of the leaves should also be properly sprayed.
