How much is lotus root per jin now? Detailed explanation of scientific fertilization methods for cultivation
Lotus root is a vegetable with nutritional value and is deeply loved by consumers. Lotus root varieties are also differentiated; generally, the ones used for stewing soup and the ones for stir-frying are different types. When stir-fried, lotus root tastes crisp, and when stewed in soup, it tastes soft and glutinous, making it especially suitable for people with weak constitutions to nourish their bodies. Let's take a look below at the current lotus root price per jin? How to fertilize scientifically during cultivation?
I. How much is lotus root per jin now?
Recently, the price of lotus root has risen somewhat, with the price roughly at 2.5-6 yuan per jin, and the price will be affected by factors such as variety and market conditions. According to relevant websites, we can learn that recent market price changes for lotus root in various places are as follows:
The lotus root price at Baotou City Youyi Vegetable Wholesale Market is 3 yuan per jin;
The lotus root price at Liaoning Anshan Ningyuan Agricultural Products Wholesale Market is 2.5 yuan per jin;

II. How to fertilize scientifically during lotus root cultivation?
The growth and development process of lotus root goes through three stages. The first is from the beginning of seed lotus root sprouting to the emergence of standing leaves, which is the sprouting and growth period. The nutrients needed for growth mainly depend on the supply from the seed lotus root, so plump and strong lotus root seeds should be selected; the second is from when the plant grows standing leaves to when the rear row leaves appear, which is the vigorous growth period and is the peak period for the formation and accumulation of plant nutrients; the third is from after full flowering until the lotus root expands and fills out, which is the lotus root formation period. From the appearance of the terminal leaf, a section of lotus root grows about every 5 days, and from the beginning of lotus root formation to full expansion of the lotus root, about 20 days are needed.
Scientific and rational fertilization is the foundation for high quality and high yield of lotus root. According to data, the average ratio of nitrogen, phosphorus, and potassium nutrient uptake by lotus root is about 1:0.25:2. Taking into comprehensive consideration the seasonal utilization rate of nitrogen, phosphorus, and potassium fertilizers and the fertilizer supply performance of the soil, the recommended application ratio of nitrogen, phosphorus, and potassium for lotus root is 1:0.33:1. The lotus root root system has a relatively weak ability to absorb fertilizer and has a relatively large demand for fertilizer. Under the condition of a yield of 1500-2000 kg of fresh lotus root per mu, it is necessary to apply 20-25 kg/mu of nitrogen, 7-10 kg/mu of phosphorus, and 20 kg/mu of potassium. All phosphorus fertilizer, 50% of the nitrogen fertilizer, and 70% of the potassium fertilizer should be applied as a base application together with organic fertilizer, while the remaining nitrogen fertilizer should be applied as topdressing in two applications, and 30% of the potassium fertilizer should be applied together at the time of the second nitrogen topdressing.
When fertilizing lotus root, note that fertilization should be chosen on clear, windless, and calm days, and should be avoided at noon under the scorching sun. Before each fertilization, drain the water so that the fertilizer can be absorbed into the water, and then irrigate back to the original depth. In deep-water lotus root fields, fertilizer is easily lost, so liquefied fertilizer cannot be applied directly; solid fertilizer should be applied instead. That is, apply heavy applications of barnyard manure or green manure and bury it into the mud. When using chemical fertilizer for topdressing, first fully mix the chemical fertilizer with river mud to make fertilizer mud balls, and then apply them into the lotus root field.
