Detailed Explanation of Key Field Management Techniques for Konjac
Konjac is a rather unusual tuber vegetable, but its taste is very special, it tastes like jelly, and it has a wide planting area in our country. Growing konjac is relatively simple, but during the growing process field management must be done well, such as weeding, watering and fertilizing, etc. Only then can the yield of konjac be guaranteed, so how should it be managed when planting? Below, the editor brings you the field management techniques for konjac, let's take a look!
1. Cultivation and Weeding
Cultivation and weeding are very important for the growth of konjac, especially from July to September, as this period is the vigorous growth period of konjac. Timely weeding can promote the expansion of konjac tubers and benefit the growth of konjac. During cultivation, pay attention to the weather conditions; it should not be done in rainy weather, and cultivation should not be too deep, to prevent damage to the konjac roots. When weeding, try to use manual weeding methods and reduce the use of herbicides, to prevent herbicides from harming the konjac plants. If the temperature is too high and the shade is poor, then it should be done when the light is weakened.
2. Reasonable Topdressing
As just mentioned, the vigorous growth period of konjac is around August, and this period is also when konjac has the greatest fertilizer demand. At this time, topdressing should be mainly potassium fertilizer, supplemented by nitrogen and phosphorus. Sufficient potassium fertilizer can enhance the growth ability of konjac and promote tuber expansion. The application of nitrogen fertilizer should be controlled to prevent excessive vegetative growth of the plants. During the growth period of konjac, topdressing should be done at least twice; the first is during the corm conversion period of konjac. The second is the expansion period. These two periods are both important periods for konjac growth, and sufficient nutrients must be guaranteed to meet the growth of konjac.
3. Water Management
Konjac is a crop that prefers moisture, so during planting, air humidity and soil moisture must be ensured. In the middle and late stages of konjac growth, the soil water content should be maintained at about 75%. It should not be too much or too little; too much will reduce soil permeability, hinder root nutrient absorption and respiration, and affect plant growth. Too little will inhibit the expansion of konjac tubers and reduce yield. Therefore, watering should follow the principle of frequent light watering to ensure that moisture is within the suitable range required by konjac. In September, reduce soil moisture to about 60% to increase nutrient accumulation in the tubers, prevent blockage of dry matter accumulation, and avoid reducing konjac quality and yield.
4. Pest and Disease Control
Pest and disease control for konjac is an indispensable management task, especially in the middle and late stages, which are periods of high incidence of konjac pests and diseases. We must strengthen management, disinfect regularly, and control the application of water and fertilizer well to prevent waterlogging and fertilizer damage. Frequently observe the growth of konjac plants, and promptly remove diseased plants once found. Then check the specific disease and use the corresponding agent for disinfection. Once common konjac pests and diseases occur, they have basically lost their treatment value, so we mainly focus on prevention.
The above is a brief introduction to konjac field management techniques; the management of konjac is closely related to its growth. If management is poor, konjac will develop various problems, seriously affecting its growth and reducing planting benefits, and in severe cases it can lead to total crop failure.
