How to grow nephritis grass

Nephritis grass is also called apricot leaf rabbit ear wind, wrinkled leaves, calla grass, it is a kind of annual herb growing in rural grassland, hillside and other land, mainly planted in Yunnan at present. Nephritis grass has the effects of clearing heat, removing dampness, relieving cough and detoxification. It is often used to treat nephritis, cystitis, bronchitis, dysentery, etc., and also has certain curative effects on knife and gun injuries. So how does Nephritis grow? Let's take a look at how it is grown.

1. Land selection and preparation

Nephritis grass is extremely resistant and has no requirements for planting land. Generally, the land that can grow crops can be used to grow nephritis grass, and some plots that cannot grow crops can also be used to grow nephritis grass. Then when we choose to plant land, we try our best to choose soil that is convenient for irrigation, transportation, fertile soil and good permeability. The second is to plant away from pollution sources, so as not to affect the quality of medicinal materials. When preparing the soil, deep ploughing is suitable for sufficient farm manure, combined with deep ploughing, mixing the soil and fertilizer, then leveling and planting, ridging and furrowing can wait for planting.

2. Scientific reproduction

The most common way of reproduction is seed reproduction and subplant reproduction. Seed propagation is also the most commonly used planting method. Under normal circumstances, we will evenly spread the seeds of nephritis grass in the whole field for cultivation. Sowing is generally done by drilling, and the row spacing between each row is about 35 cm. The propagation of plants was carried out by using the newly grown rhizomes of Nephritis grass. After the plants were divided, they were planted according to the density of 30 cm in row spacing and 25 cm in plant spacing.

3. Watering and fertilizing

When planted by seed propagation, it usually takes about one to three weeks to emerge, while ramets generally grow new roots about five days after planting. During the seedling period of nephritis grass, we should keep a certain humidity in the field, usually about 40%. After the seedlings emerge, if there is no rainfall, it is necessary to continue watering in time to promote the growth of seedlings. During this period, reasonable thinning and replenishment are also needed. After planting, it is necessary to carry out the first topdressing, which can be irrigated with excrement and urine, usually nitrogen fertilizer. In the whole growth process of nephritis grass, we need irregular watering, from seedling to harvest, the number of watering is about six to eight times, and the number of topdressing is about three to four times.

4. Intertillage and weeding

Intertillage and weeding are also very important in the growth process of nephritis grass. Because weeds grow very fast during the growth of nephritis grass, we need to weed regularly. Generally, the first intertillage weeding is carried out after planting. The intertillage is usually based on shallow tillage, so as not to hurt the roots of nephritis grass. The second is weeding. We have to weed according to the growth of weeds, as early as possible to reduce nutrient consumption. Finally, it is necessary to loosen the soil irregularly in the later stage to enhance the permeability of the soil, such as after continuous rainfall, after more washing and watering, etc.

The above is the planting technology of nephritis grass, I believe everyone has a general understanding of the planting method of nephritis grass. Today's sharing of Xiaobian ends here. If you encounter some problems that other Xiaobian did not mention in the later planting process, you can leave a message for Xiaobian.
