Weeding methods and matters needing attention of konjac

Recently, the development of konjac konjac is becoming more and more pear trees, and the planting area of konjac is also increasing, but growers often encounter a variety of weeds, which cause great losses to farmers. So how to weed the konjac? Let's get to know it with the editor.

1. Artificial weeding

Konjac weeding or artificial weeding is higher, but manual weeding is very easy to lose to the root of konjac, and it is time-consuming and laborious, generally requires weeding three times, once when konjac has just sprouted, you can use a hoe to cover the weeds, which can directly crush the grass and increase the living soil layer. The second time in July, the weeds in the konjac field were pulled out directly, and their roots were turned over and laid in the ground, and the weeds rotting can also add nutrients to the konjac. The third time in August, it was pulled out manually and spread in the ditch, manual weeding was time-consuming and laborious, and the root system of Amorphophallus could be pulled out together when weeding.

2. Herbicide weeding

Herbicides generally control weeds for the first time from mid-April to early May, during which the effect of using herbicides is the most obvious, because konjac develops relatively late and generally germinates at the end of May, while weeds generally grow in March-April. At this time, spraying herbicides can effectively eliminate weeds without harming Amorphophallus. After konjac germination, you can also use herbicides to control weeds, but you can only use quizalofop, not glyphosate herbicides. If the weeds are particularly large, quinoxaline is useless, so when using herbicides, you must use them in time. Be sure to use them when the weeds are small.

3. Cover with grass control

Mulching cultivation is to cover the soil moisture with loose hair, straw, corn stalk and other mulch after planting konjac. This weeding method can not only control weeds, but also conserve water and fertilizer and promote the growth of konjac. From the perspective of weeding, artificial weeding is too tiring, because the grass root and konjac root are intertwined, and it is possible to pull out the konjac root system when pulling the grass. Although the herbicide is convenient, it will also affect the growth of konjac and the yield of konjac. So the best way to control weeds is to cover the weeds, which not only does no harm, but also has many benefits to konjac.
