How to plant Niu Li

Niulli is a kind of traditional Chinese medicine with strong efficacy. Due to the large market demand, but the wild resources are on the verge of drying up, artificial cultivation has sprung up and expanded rapidly within a few years. Many people have achieved wealth by planting it, so more and more people are attracted to it. So how should Niu Li plant it? Let's get to know it.

1. Land selection and preparation

Niuli is a deep-rooted plant, which has strict requirements on soil, and is suitable for sandy loam with deep soil layer, loose soil and good drainage, so it is necessary to observe whether the local soil field accords with the growth of Niudali in the field when deciding to plant. After selecting the plot, apply more than 5000 kilograms of rotten soil fertilizer and 50 kilograms of ammonium bicarbonate per mu, then rake fine and level it, and then furrow and ridge, requiring a ridge width of about 40--50cm and a high 25cm. In order to prevent the ridge from collapsing in cloudy and rainy days, it is necessary to use tools on both sides.

2. Sowing seeds

The seed propagation method used in cattle planting is to collect the pods when they are mature, take out the seeds after drying, and sow the seeds which are full, mature, damage-free and disease-free. Soak the seeds in warm water of 40-50 degrees for several hours before sowing and germinate in an environment with a temperature of 40 degrees and a humidity of 85%. Sowing can be carried out when the seeds sprout, and when sowing, seed dressing and sterilization can be used to reduce the threat of disease. Sowing in furrows at the top of the ridge, the seed plant spacing is 3-5cm, and the seed is covered with 3cm after sowing, about 200g per mu.

3. Seedling stage management

When the seedlings grow to 1-2 true leaves and 2-3 true leaves, the seedlings should be carried out once to increase the ventilation and light transmittance of the seedlings and make them emerge neatly. After that, it is necessary to control the seedling distance of 7-10cm, so as to remove weak seedlings, dead seedlings and exuberant seedlings, leaving seedlings of the same size to fix seedlings, so as to facilitate management. If you want to go on the market early, you can leave a larger gap, and if you want to go on the market later, the spacing can be denser.

4. Field management

Cattle grow slowly, and there are more weeds in the seedling stage, which affects its absorption of nutrients, and its growth will be slower, so it is necessary to carry out intermediate ploughing and weeding reasonably according to the growth status of fields and seedlings. In addition, topdressing 3 times in the growing period, the first time in the plant growth above 30cm, topdressing urea 10 kg per mu; the second time in the peak growth season, urea 8 kg per mu, can be combined with watering, so that fertility can be absorbed by it as soon as possible; the third time in the fleshy root expansion, it is necessary to topdressing phosphate and potassium fertilizer to increase yield, 10 kg diammonium phosphate per mu and 5 kg potassium sulfate per mu.
