Method for plan seven-leaf and one-flower seeds

The planting of flowers with seven leaves and one branch is generally carried out in shady places with shade and convenient drainage and irrigation. A flower with seven leaves and one flower is a shallow-rooted plant. Its growth rate is slow, its seedling raising time is long, and its requirements for soil are high. When preparing soil, clean up the stones and weeds in the ground, knock down the clods and level the ground. Soil preparation should be combined with fertilization, and the base fertilizer planted in Paris is generally decomposed organic fertilizer.

First, sow and raise seedlings.

Seven leaves and one flower are usually sown and cared for every year 1 month. Seeds with full grains, no pests and diseases and no mildew should be selected. Then the seeds are exposed to the sun for three days, mixed with river sand to accelerate germination, while keeping the river sand moist and ensuring the seeds to breathe fully.

Disinfect the soil with carbendazim before sowing, and then sow. When sowing, the seeds should be ditched according to the row spacing of 30 cm -50 cm, and it usually takes about one week to emerge. During seedling emergence, soil moisture should be maintained to promote seedling emergence and growth.

Second, scientific planting.

Generally, the seedling raising time of seven-leafed flowers is about one month, which means that the seedlings of seven-leafed flowers can be transplanted after one month, while some seven-leafed flowers have to wait three years to dig out the seedlings and transplant them.

Transplanting is generally carried out according to the row spacing of 30 cm and the plant spacing of 20 cm. If there is no shade in the planting area after transplanting, it is necessary to build a shade shed in advance, and pay attention to planting with soil when transplanting seedlings to improve the survival rate of seedlings with seven leaves and one branch.

Third, on-site management

The planting time of flowers with seven leaves and one branch is generally in March and April. There is more rain in March and April, so it is not necessary to water after transplanting, but attention should be paid to proper drainage at this time to discharge excess water into the field. If it is dry weather, water the seedlings properly.

Under normal circumstances, from September to October, the flowers with seven leaves and one flower are cultivated and weeded without deep ploughing, so as not to damage the roots of the flowers with seven leaves and one flower. The bell tower needs topdressing two or three times a year, and topdressing is mainly Woye amino acid water-soluble fertilizer.

Fourth, control pests and diseases.

The main disease of Paris polyphylla is root rot, which mainly harms the root system of Paris polyphylla. The cause of the disease is root rot and plant death caused by too much water in the field. If root rot occurs, Bordeaux mixture can be used to control it.
