Detailed Explanation of Key Techniques for Field Management of Lotus Root
Lotus root is a vegetable that many people enjoy eating very much, and growing lotus root has become the main occupation of many people. Unlike other vegetables, lotus root spends its entire growth period in water, so the growing method is naturally different as well. Therefore, when we grow it, we cannot manage it according to the management methods for ordinary tuber vegetables. So how should we manage lotus root? Today, the editor brings you the management methods for lotus root, so let's take a look below!
1. Water and Slurry Management
As the editor just said, lotus root lives in water throughout its entire growth period, so the most important management task when growing lotus root is water and slurry management. However, although lotus root is an aquatic vegetable, it has different water requirements at each growth stage. For example, during the period from planting the lotus root to the standing leaf stage, the water level should not be too high, to prevent the surface temperature from being too low, which would hinder the sprouting of the planted lotus root. But if the temperature is relatively high at this stage, then the water level can be appropriately raised to about 7 cm. If the temperature drops, then the depth needs to be increased by about 5-10 cm. The depth of the water level should increase as the growth rate of the lotus root accelerates.
2. Timely Topdressing
The growth of lotus root not only has a large demand for water, but it also greatly likes fertilizer. Its demand for nutrients is very large, so during the growth process, timely topdressing should be carried out according to the growth condition of the lotus root. However, when topdressing, attention should be paid to the amount and concentration, and it must absolutely not be excessive. If the fertilizer concentration is too high, it will generate a large amount of heat, causing the roots to be unable to bear it and resulting in root burn. Therefore, when topdressing, the principle of applying more frequently but in small amounts should be followed, and some new high-fat film can be appropriately sprayed to improve the utilization rate of the fertilizer. It can also reduce the evaporation rate of the fertilizer and adjust the water absorption capacity of the lotus root.
3. Growth Period Management
Growing lotus root places relatively high demands on the quality and appearance of the lotus root, so in order to improve the quality of the lotus root, during the growth period of the lotus root, agents such as Diguo Zhuangtiling can be sprayed to promote the expansion of the lotus root tubers. This enhances the nutrient absorption of the tubers, ensures comprehensive nutrient transport, improves the growth vitality of the tubers, and further increases the quality and weight of the lotus root tubers. After appropriately spraying growth regulators, the growth of the lotus root tubers is fully supported, the flesh becomes crisper, the moisture content increases, and the yield is noticeably improved. However, the use of growth regulators must be controlled well; excessive use can easily lead to excessive vegetative growth of the lotus root.
4. Disease Control
Disease is the most basic and also the most important management task in the growth process of lotus root. Common pests and diseases of lotus root include aphids, viral diseases, and so on. No matter what kind of pest or disease it is, it poses a very great threat to the growth of lotus root. Therefore, before and after planting, we must do a good job of prevention and control. When disinfecting, an appropriate amount of new high-fat film can be used together, as new high-fat film can effectively improve the efficacy of the pesticide. When spraying, pay attention: do not use pesticides blindly, to prevent causing a certain inhibitory effect on the growth of the lotus root as well.
The above is a brief introduction to the field management methods for lotus root. The economic benefits of growing lotus root are quite good. This is because not only the tubers of lotus root have value; its flowers and lotus seeds, among others, are also very popular in the market. However, growing lotus root is rather troublesome, and it is not easy to manage in water, so we still hope everyone can consider it carefully before planting. That is all for today's introduction.
