Causes and Control methods of Seedling emergence of Sugarbeet

Sugar beet has a wide planting area and is cultivated all over the country, but for growers, the poor emergence of sugar beet will seriously affect the planting income of sugar beet and reduce the income of farmers. So what is the reason for the poor emergence of sugar beet? How to prevent and cure it? Come and have a look with the editor.

1. Chemical fertilizer is applied year after year.

Nowadays, with the widespread use of chemical fertilizer, many farmers will choose to use chemical fertilizer to increase production, but the problem of abuse of chemical fertilizer has become increasingly prominent, such as unreasonable use of chemical fertilizer and low utilization rate of yoga, such as environmental pollution and ecological damage. Frequent use of chemical fertilizer is an important reason for increasing production of soil consolidation, while sugar beet seedlings are weak, top soil capacity is poor, soil consolidation will inhibit the emergence of sugar beet seedlings.

Control methods: more application of organic fertilizer, organic fertilizer has comprehensive nutrients, long fertilizer effect, less pollution, increase soil fertility, improve crop yield and quality and other important roles. After retting, it can accelerate the decomposition and release of nutrients, reduce the harm of diseases and insect pests, improve soil aggregate structure and reduce soil consolidation.

2. The soil cover is too thick.

The top soil ability of sugarbeet seedlings is poor, the general sowing depth is controlled between 2-2.5 cm, once the sowing depth is more than 5 cm, it will make it difficult to unearth. And sowing requires uniform seed, consistent depth to ensure that there is no missing sowing, no floating seeds, no broken strips.

Prevention and control methods: when sowing, the soil cover should not be too thick, try to control within 2-5 cm, too shallow and too deep are not conducive to sugar beet emergence, which requires special attention.

3. Improper use of herbicides

In the plots with serious damage to weeds, many farmers are convenient to save money, and often do not consider whether the herbicide residue is effective or not to sugarbeet seedlings, spraying some herbicides harmful to the growth of sugarbeet, resulting in serious death of sugarbeet seedlings.

Prevention and control methods: when using herbicides, we should pay attention to the amount and concentration of herbicides and the types of herbicides, and the herbicides with low toxicity and high efficiency should be used to reduce the impact of herbicides on sugar beet as much as possible. Manual weeding is recommended if there are few weeds.

4. Temperature influence

Sugarbeet seeds can also germinate at low temperature, which provides conditions for early sowing of sugarbeet. Generally, there will be refreezing phenomenon in early spring. At this time, early sowing, slow germination at low temperature, slow germination, and seedling emergence may be delayed for about one month. In this way, the seedling growth in early spring is weak and the root system is underdeveloped.

Control method: the seed can be soaked and germinated before sowing, which can greatly reduce the emergence time of the seed.

The above are the reasons for the poor emergence of sugar beet and the introduction of control methods, hope to help you, want to know more related knowledge, please pay attention to us.
