Onion rot seriously affects the value of onions, and timely pesticide control prevents economic losses. Let's take a look at the specific prevention methods along with the small series:
First, the decay caused by the disease. Control measures: 1. Pay attention to the rotation, avoid heavy crops with onion and garlic crops. 2. Apply fermented fertilizer to prevent fertilizer from carrying bacteria. 3. Try to use ridges. 4. The application of nitrogen fertilizer in the growing season should be combined with nitrogen, phosphorus and potassium. 5. Pay attention to timely drainage during bulb formation to avoid long-term water accumulation. 6. Spray new high-fat film to prevent infection of pathogens, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and protect the growth.
Second, the rot caused by the lack of. Due to the low temperature in early spring, the accumulation of ammonium nitrogen in the soil is excessive, affecting the absorption of elements such as calcium, potassium and magnesium, resulting in the occurrence of physiological diseases lacking the above-mentioned fertilizer elements. Excessive application of nitrogen fertilizer during the growth period also causes the lack of these elements. It is recommended that the pesticide network should use roots and micro-fertilizers to induce roots to absorb, digest and release nitrogen, phosphorus, potassium and various trace elements in the soil.
Third, the decay caused by stagnant water. At the end of the onion growth, the leaf sheath is loose and the gap is large. The excessive water in the field will be immersed in the sheath of the fallen plant; the rain will be immersed in the sheath of the non-falling plant. All of the above factors can cause the bulb to rot. To this end, attention should be paid to drainage and early harvesting.
Fourth, the decay caused by insects. Ground wounds such as ground tigers, golden worms, and mantles are wounds caused by onions, which can easily cause mold invasion and mold damage, and can cause invasive diseases. Pesticide manufacturers suggest that the combination of root application and special medicine should be used in time to improve the control effect.
