The latest course of field management techniques and methods of konjac

Konjac is a kind of peculiar tuber vegetable, but it tastes very special and tastes like jelly. It has a wide planting area in our country. The cultivation of konjac is relatively simple, but field management needs to be done well in the planting process, such as weeding, water and fertilizer work, and so on. In order to ensure the yield of konjac, so how to manage when planting? The following editor brings you the field management technology of Konjac, let's have a look!

1. Ploughing and weeding

Weeding is very important for the growth of konjac, especially from July to September, when it is the peak growth period of konjac. Timely weeding can promote the tuber expansion of konjac, which is beneficial to the growth of konjac. When ploughing, we should pay attention to the weather conditions, not in cloudy and rainy weather, ploughing should not be too deep, to prevent damage to the root of konjac. When weeding, try to use artificial weeding to reduce the use of herbicides and prevent herbicides from harming konjac plants. If the temperature is too high and the shade is poor, it should be done when the light decreases.

2. Reasonable topdressing

As I just said, the growth period of konjac is around August, which is also the time when konjac needs the largest amount of fertilizer. At this time, topdressing should be mainly potassium fertilizer, supplemented by nitrogen and phosphorus, sufficient potassium fertilizer can enhance the growth ability of konjac, promote tuber expansion, to control the application of nitrogen fertilizer, to prevent plant growth. During the growth period of konjac, topdressing should be done at least twice, first, when the konjac changes its head. The second time is the expansion period, these two periods are important periods for the growth of konjac, to ensure adequate nutrition for the growth of konjac.

3. Water management

Konjac is a relatively wet crop, so it is necessary to ensure air humidity and soil moisture when planting. In the middle and later stages of konjac growth, the water content of the soil should be kept at about 75%. Not too much or too little, too much will reduce soil permeability, hinder root nutrition absorption and respiration, and affect plant growth. If too little, it will inhibit the expansion of konjac tubers and reduce the yield. Therefore, watering should be based on the principle of more watering and a small amount of water to ensure that the moisture is within the appropriate range of demand for konjac. In September, the soil moisture was reduced to about 60%, which increased the nutrient accumulation of tubers, prevented dry matter accumulation from being blocked, and reduced the quality and yield of konjac.

4. Pest control

The pest control of konjac is an indispensable management work, especially in the middle and later period is the high incidence period of konjac diseases and insect pests. We must strengthen management, disinfect regularly, control the application of water and fertilizer, and prevent and control waterlogging and fertilizer damage. The growth of konjac plants is often observed and should be pulled out in time after diseased plants are found. Then check for specific diseases, and then use the corresponding agents for disinfection. The common diseases and insect pests of konjac have basically lost their therapeutic value after the onset of the disease, so we mainly focus on prevention.

The above is a brief introduction to the field management technology of konjac. The management of konjac is closely related to the growth of konjac. If poor management, konjac will have a variety of problems, seriously affect the growth of konjac, reduce the efficiency of planting, serious will lead to konjac production.
