Causes of low yield of konjac and preventive measures

Konjac itself is a high-yielding cash crop, but many farmers are always asking about the low yield of konjac, so what is the reason for the low yield of konjac? How to solve the problem and increase the output of konjac? Let's get to know it with the editor.

1. The quality of taro is poor.

The serious disease of seed taro, mechanical damage, large hilum, uneven age and size, etc., will affect the growth and development of konjac, lead to various problems during the growth period, indirectly affect the final yield, and lead to underground yield.

Preventive measures: select the seed taro before sowing, select the corm without damage, disease spot and rot as the seed taro, and strictly control the quality of the seed taro.

2. There are many diseases and insect pests

There are 14 kinds of common diseases of taro, and the population is complex, which is often caused by diseases and insect pests. Soft rot of konjac and white silk disease are called the cancer of konjac. At present, there is no special control agent. Once infected, the light will reduce the yield, and the heavy will lose the harvest.

Preventive measures: dig deep into the soil before sowing, reduce the base number of diseases and insect pests, and apply disinfectants if possible to reduce the incidence of diseases and insect pests. Do you choose biological pesticides with high efficiency and low toxicity to control diseases and insect pests? use 30 grams of agricultural streptomycin sulfate or 30 grams of copper master per mu, 60 grams of Longke bacteria, and spray 40 kilograms of water to control konjac diseases and insect pests. The preventive effect was better when the drug was used once every 10-15 days for 3-4 times.

3. Improper cultivation mode.

Such as selecting paddy fields, continuous cropping fields, barren fields, yellow soil and other fields to plant konjac, sowing before winter, or adopting bad interplanting patterns such as net cropping or excessive shading will affect the yield of konjac.

Preventive measures: gentle slope or flat land with high topography and good drainage should be selected before planting, and the sandy loam with deep layer, fertile soil, high organic matter content and light texture is the best.

4. Improper management

In fertilization, the use of immature farm manure, partial application of nitrogen fertilizer or potassium chloride compound fertilizer; seed taro and soil without chemical treatment, sowing too deep or too shallow; no high ridge cultivation, poor drainage, no chemical prevention during the growing period of konjac, uncleaned countryside, etc.; all will lead to frost damage, fertilizer damage, water damage, grass damage, drought damage and so on, resulting in reduced production.

Preventive measures: fertilization should be reasonable, organic fertilizer or farm manure must be fully mature, taro and soil must be sterilized before sowing, sowing depth should be appropriate, should not be too high or too low. To select plots, we must choose gentle slopes or flat land with high topography and good drainage, and clean up the fields in time to prevent diseases and insect pests, increase production and improve quality.
