What Causes Poor Sugar Beet Emergence? Plus Control Methods
Sugar beet is widely planted and cultivated all over the country, and for growers, poor sugar beet emergence can seriously affect the planting returns of sugar beet and reduce farmers' income. So what causes poor sugar beet emergence? How should it be controlled? Let's take a look together.
1. Continuous application of chemical fertilizers for years
Nowadays, the use of chemical fertilizers is widespread, and many farmers choose to apply chemical fertilizers to increase yields, but the problem of fertilizer abuse has also become increasingly prominent. The environmental pollution and ecological damage caused by irrational fertilizer use and low utilization rates are serious. Frequent use of chemical fertilizers is an important cause of increased soil compaction, and sugar beet seedlings are weak and have poor soil-penetrating ability, so soil compaction will inhibit sugar beet emergence.
Control methods: Apply more organic fertilizer. Organic fertilizer has important effects such as comprehensive nutrients, long fertilizer efficiency, less pollution, increased soil fertility, and improved crop yield and quality. After composting and decomposing it, it can accelerate the decomposition and release of nutrients, reduce disease and pest damage, and also improve soil aggregate structure and reduce soil compaction.
2. Too thick soil covering
Sugar beet seedlings have poor soil-penetrating ability, and the sowing depth is generally controlled between 2-2.5 cm. Once the sowing depth exceeds 5 cm, it will make it difficult for them to emerge from the soil. Also, when sowing, seeds are required to be distributed evenly and at a consistent depth, ensuring no missed sowing, no floating seeds, and no broken rows.
Control methods: When sowing, the soil covering should not be too thick, and it should be controlled within 2-5 cm as much as possible. Too shallow or too deep is not conducive to sugar beet emergence, and this point requires special attention.
3. Improper use of herbicides
In plots with severe weed damage, many farmers, to save money and for convenience, often do not consider whether residual herbicide damage will affect sugar beet seedlings, and spray some herbicides harmful to sugar beet growth, causing severe sugar beet seedling death.
Control methods: When using herbicides, pay attention to the amount and concentration of the agent and the type of agent. Choose low-toxicity and high-efficiency herbicides, and reduce the impact of herbicides on sugar beet as much as possible. If there are few weeds, manual weeding is recommended.
4. Temperature effects
Sugar beet seeds have the characteristic of being able to germinate even at low temperatures, which provides conditions for early sowing of sugar beet. Generally, there is a return-freezing phenomenon in early spring. If sown too early at this time, germination is slow under low temperatures and may be delayed for a long time. Emergence time may be delayed by about one month, so in early spring the seedlings grow weakly and the root system is not well developed.
Control methods: Before sowing, the seeds can be soaked and pregerminated, which can greatly shorten the seed emergence time.
