What causes lodging in sesame? A detailed explanation of the latest control measures

We are all fairly familiar with sesame. It can be divided into white sesame and black sesame, and their cultivation also differs somewhat; in daily life we come into contact with black sesame more often. During sesame cultivation, lodging can occur, seriously harming the yield and quality, so how should sesame lodging be controlled? Let's take a look together.

1. Causes of lodging

The main reason is poor lodging resistance of the variety. The plants of some varieties have taller stems, and the fibrous tissue of the stems is weaker. They are themselves relatively tolerant of poor soil, but once in an environment with sufficient fertilizer and water, their stems grow rapidly yet are not thick and sturdy enough, resulting in lodging. In addition, improper management, such as excessive water at the seedling stage, can lead to leggy seedlings; excessive density; poor air permeability; and excessive nitrogen fertilizer application all cause excessive vegetative growth, thin and weak stems, and very easy lodging. In addition, severe disease is also a factor that can cause lodging, and failure to control stem-boring insects in time can also cause lodging.

2. Control measures

1. First, choose varieties with strong resistance to pests and diseases and strong lodging resistance, which can greatly reduce the occurrence of lodging.

2. During planting, carry out intensive and careful cultivation and deepen the plow layer to create a good soil environment for the sesame root system; this is also one of the main measures for controlling sesame lodging.

3. Plant at a reasonable density to improve field air permeability, so that the plants grow robustly and the stems are thick and sturdy.

4. Maintain balance between nitrogen and phosphorus so as to avoid applying too much nitrogen fertilizer, which causes excessive vegetative growth.

5. Pay attention to pests and diseases to prevent them from causing stem breakage and lodging.

6. Plant growth regulators can be used to promote rooting and restrain seedling growth, controlling the vegetative growth of the plants so as to avoid the phenomenon of tall stalks and weak stems.

7. Do a good job of drainage on cloudy days to prevent excessive vegetative growth. In dry conditions, water promptly, but by all means avoid flooding irrigation, so as to prevent lodging.
