Detailed Explanation of Field Management Techniques for Jicama
Jicama is called sweet potato in many places, and it is cultivated almost everywhere in China. Jicama has relatively comprehensive nutrients, is fairly simple to grow, and also yields a high output. However, this is also based on proper management. Field management of jicama is very important and is one of the cultivation tasks that ensures a high yield. So how should field management of jicama be carried out? Below, the editor brings you the field management methods for jicama. Let's take a look!
1. Cultivation and Weeding
The main edible part of jicama is the underground tuber, so cultivation and weeding of jicama is the primary management task. Before the seedlings grow to about 8 cm and before the vines cover the ground, complete the first cultivation and weeding task. When cultivating, pay attention to the depth; it should not be too deep, because the roots of jicama are relatively shallow, and if it is too deep, the roots are easily damaged. It can also prevent the fleshy roots from being exposed outside, which would affect tuber growth and reduce quality. Combine weeding with cultivation to prevent weeds from occupying the ground growth space of jicama, competing for growth nutrients, and causing a decline in yield.
2. Water and Fertilizer Management
The seedling stage is the most critical time for jicama growth and is also when the demand for water and fertilizer is relatively high, so water and fertilizer management must be done well during this period. When topdressing, do it together with loosening the soil; each time the soil is loosened, apply topdressing once to improve soil fertility, prevent nutritional deficiencies in jicama, and promote the growth of jicama. When jicama reaches the expansion stage, apply heavy fertilizer. In summer, when there is high temperature and drought, water promptly, but there should not be too much water; in rainy weather, drainage management must also be done well. If there is too much accumulated water, it is easy to cause jicama to change color, trigger pests and diseases, and lead to rot, which has a relatively large impact on yield and quality.
3. Management During the Expansion Stage
The expansion stage is a relatively critical period in the growth process of jicama, usually reached about 3 months after planting. During this period, with high temperature and high humidity, jicama has extremely strong growth ability and a large leaf area, so management during this period is very important. First, we must control the growth of jicama stems and leaves. When growth is fast, avoid turning the vines and appropriately spray foliar fertilizer, which is very beneficial to tuber development and can also increase the yield of jicama. If drought occurs during the expansion stage, water promptly, but do not use flood irrigation.
4. Harvesting and Seed Reservation
The growth cycle of jicama is not very long; from sowing to harvest it is about half a year, and the harvest time varies depending on the planting region and variety. For example, mid-to-late maturing varieties should be harvested promptly before winter, because these varieties have thin skin and poor cold resistance. Secondly, we can also decide according to the direction of consumption. If it is to be eaten raw, then it should be harvested early; early-harvested jicama has plump and juicy flesh and good taste, but it is not suitable for storage. Therefore, there is no specific harvest time. When harvesting, everyone should consider the above aspects comprehensively.
The above is a brief introduction to the field management of jicama. The cultivation of jicama covers a relatively widespread area in China, but many people also fail in growing it. Most of the reasons are caused by not doing a good job in field management, so everyone must strengthen their own planting management techniques! That is all for today's introduction.
