Planting technique of Saxifraga

Saxifraga, also known as Shihe leaf, golden thread hanging hibiscus, tiger ear, etc., the whole grass can be used as medicine, with the effect of dispelling wind and clearing heat, cooling blood and detoxification, and is distributed all over our country. As its root system is developed, it is the raw material of many kinds of proprietary Chinese medicine, the market demand is increasing, and many areas begin to cultivate it artificially, so how to plant Saxifraga? Let's get to know it.

1. Land selection and preparation

Saxifraga likes a cool and humid environment and requires the soil to be moist and fertile. It is best to choose sandy loam with high organic matter content and good drainage. After selecting the land, do a good job of soil preparation, turn the plot 20-30 cm deep, and use the sun to kill the source of diseases and insect pests in the soil, at the same time, according to the fertility of the soil, apply appropriate amount of organic fertilizer or farm manure as base fertilizer, rake fine leveling and make beds, waiting for planting.

2. Methods of reproduction

The main propagation methods of Saxifraga are seed propagation and plant propagation. Seed propagation is generally sown in March-April in spring, when the temperature and water can meet its seed germination and promote seedling growth. The method of strip sowing or hole sowing can be used to sow the ditch on the border surface, spread the seeds evenly into the ditch, cover the soil and water. On the other hand, hole sowing should open holes on the border surface according to a certain distance between plants and rows, and sow seeds. Generally, 3-4 seeds are used for each hole, and the same soil covering and watering can also cover the grass to keep warm and moisturize to facilitate seedling emergence, but the cover grass should be removed in time after emergence. Ramet reproduction can be done at any time, but the best time is in summer and autumn, when the small plants on the stolon of the mother plant are separated and replanted.

3. Field management

Weeds should be weeded in time after emergence, lest weeds affect the growth of seedlings. When seedlings grow 1-2 leaves, and time seedlings grow 4-5 leaves, seedlings should be fixed in time. Saxifraga has strict requirements for temperature and light, and the suitable growth temperature is 15-25 degrees. It can survive in 5 degrees low temperature in winter, but it will cause death, so we should pay attention to it. It likes the moist environment, so it should pay attention to moisture when growing, often water, keep the soil moist, especially in drought, and do a good job of drainage measures in the rainy season to avoid rotting roots. At the same time, we should also pay attention to the light, suitable to grow in the semi-overcast environment, it is difficult to survive in the full sunlight, to build a shade shed, do a good shade treatment. At the same time, fertilization should be done according to soil fertility and plant growth to promote plant growth.
