Detailed Explanation of Key Techniques for High-Yield Lotus Root Cultivation
Lotus root is a very common vegetable in our daily lives. Its nutritional value is extremely high, and it is loved by many people. Therefore, many people are now growing lotus root, and when growing lotus root, yield is a issue that everyone is very concerned about. So how should lotus root be grown to achieve high yield? Today, the editor brings you the high-yield cultivation techniques for lotus root. Let's take a look below!
1. Timely Weeding
Weeds have a very large impact on the growth of lotus root. In the early stage of lotus root growth, its growth rate is very slow. The field is also very prone to weeds, and weeds will rob the lotus root of growth nutrients, causing insufficient nutrients for lotus root growth, so we must pay attention to doing a good job in weeding. Generally, we should weed once a month from May to June, and directly tread the pulled weeds into the mud to let them naturally rot. If the weeds have strong vitality, then we need to dry them in the sun and increase the number of weeding times. The main thing is still to carry it out reasonably according to the actual field conditions.
2. Reasonable Topdressing
Reasonable topdressing is also a key measure to ensure lotus root yield. During the germination stage after lotus root is planted in the field, we should apply an appropriate amount of organic fertilizer. Sprinkle the organic fertilizer between the rows of lotus root, then turn it into the mud to increase water temperature and ground temperature and ensure its normal growth. Then during the standing leaf growth period of lotus root, that is, when the lotus root plants grow 4-6 standing leaves, carry out the second fertilization. The fertilizer can be farmyard manure or chemical fertilizer, etc. If conditions permit, an appropriate amount of cake fertilizer can also be added to ensure rapid growth of lotus root and provide it with sufficient nutrients.
3. Water Control
Water is an indispensable condition for the growth of lotus root. After lotus root is planted, generally there will be no shortage of water. What we mainly pay attention to is the depth of irrigation water in the field, which should be adjusted according to climate changes and the actual growth conditions of lotus root. Around May each year, in order to increase the ground temperature and allow lotus root to grow normally, shallow water irrigation should be carried out appropriately. Then starting in June, the temperature gradually rises, and standing leaves will also begin to grow. At this time, the irrigation amount can be appropriately increased.
4. Timely Field Drying
During the entire growth period of lotus root, field drying should be carried out about twice. The first time should be in May, release all the water in the lotus root field and dry the field until small cracks appear in the lotus root field. Doing this can effectively increase the temperature, promote the downward growth of lotus root roots, and enhance the wind damage resistance of lotus root plants. Then dry the field again in June, keeping the time at about 4 days. However, note that field drying should not be excessive. If the cracks in the lotus root field become too large, the soil will harden and affect the growth of lotus root. In severe cases, it will cause the lotus root to turn yellow and die.
The above is a brief introduction to high-yield cultivation techniques for lotus root. That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
