Latest Key Technical Points for Field Management of Jicama
Jicama is called sweet potato in many places, and it is cultivated almost everywhere across China. Jicama's nutrients are fairly comprehensive, and it is relatively simple to grow, with a relatively high yield as well. But this is also built on the basis of proper management; field management of jicama is very important, and it is also 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 have covered the ground, do the first cultivation and weeding task well. 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. When cultivating, combine it with weeding to prevent weeds from occupying the ground growing space of jicama and competing for growth nutrients, which would lead to a decrease in yield.
2. Water and Fertilizer Management
The seedling stage is the most critical time for jicama growth, and it is also when the demand for water and fertilizer is relatively large, so water and fertilizer management should be done well during this period. When topdressing, do it together with loosening the soil; each time the soil is loosened, carry out one topdressing to improve soil fertility, prevent nutrient deficiency in jicama, and promote jicama growth. When jicama reaches the swelling stage, apply heavy fertilizer. In summer, when there is high temperature and drought, water in time, but the amount of water should not be too much, and in rainy weather, drainage management should also be done well. If there is too much accumulated water, it can easily cause jicama to change color, trigger pests and diseases, and lead to rot, which has a relatively large impact on yield and quality.
3. Swelling Stage Management
The swelling stage is a relatively critical period in the growth process of jicama, usually reached about 3 months after planting. During this period of 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 need to control the growth of jicama stems and leaves; when the growth speed is fast, avoid turning the vines, and appropriately spray foliar fertilizer, which is very beneficial to tuber development and can also increase jicama yield. If drought occurs during the swelling stage, water in time, but do not use flood irrigation.
4. Harvesting and Seed Saving
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 in time before winter arrives, because this type of variety has thin skin and poor cold resistance. Second, we can also decide according to the direction of consumption: if it is for raw eating, then it should be harvested early; early-harvested jicama has plump and juicy flesh and good taste, but it is not good for storage. Therefore, there is no specific harvest time, and everyone should consider the above aspects comprehensively when harvesting.
The above is a brief introduction to jicama field management. Jicama cultivation covers a relatively wide 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.
