Causes and solving measures of empty spike in wheat

Wheat is one of the most important economic crops in China. The planting area of our country is very large, and there is often a phenomenon of empty spike in the planting process, resulting in basically no yield of wheat, resulting in huge economic losses to farmers. So what is the reason for the empty spike of wheat? And how to deal with it, let's take a look at the detailed introduction of the pro-agricultural network.

1. Climatic reasons

The climate in some areas is relatively bad, and the phenomenon of dry and hot wind often occurs in the late spring and early summer. If the wheat is in the heading stage or filling stage, the dry and hot wind will cause wheat abortion and grain filling obstruction, resulting in the phenomenon of empty spike and shrunken spike. In addition, the elimination of some varieties in the case of cold wave will also cause empty spike phenomenon, at the same time, during pollination, long-term overcast and rainy weather will lead to poor pollination or failure of wheat pollination.

Solution: planting should be carried out according to the local climatic conditions and soil conditions, and the varieties with strong stress resistance suitable for the local environment should be selected in accordance with local conditions in order to increase the yield and economic benefits.

2. Seed causes

If there is a problem with the quality of the seed when sowing wheat, it is the seed that is old or has other problems in previous years, which will also cause the phenomenon of empty spike when wheat is growing.

Solution: high quality must be selected when selecting seeds, and the quality of seeds is related to stable yield and high yield, so we must go to formal companies with guaranteed seed quality to buy.

3. Improper use of fertilizers and drugs

The improper use of fertilizers and drugs during planting is also one of the main reasons for the empty spike of wheat, for example, at the heading stage of wheat, if a large amount of nitrogen fertilizer is applied at this time, the flowering of wheat will be delayed or aborted, in addition, in the process of controlling diseases and insect pests, the use or concentration of drugs used is too high, resulting in empty spike caused by drug damage to wheat.

Solution: fertilizing and using chemicals must be reasonable and standardized, which kind of fertilizer should be used in different growth stages, and the dosage and concentration of drugs should also be controlled.

4. Diseases and insect pests

Diseases and insect pests are also one of the causes of wheat empty spike, which are mainly caused by wheat glume blight and wheat powdery mildew, which mainly harm the leaves, stems and spikes of wheat, which hinder the growth of wheat and lead to the death of wheat without timely control. The main pests are wheat whitefly, trematode and so on, which mainly suck the sap of wheat grain, which leads to the phenomenon of wheat grain dryness and empty spike in the outbreak period.

Solution: when planting, we must pay attention to the prevention and control of diseases and insect pests, not to be underestimated, timely treatment after finding diseases and insect pests, prescribe the right medicine to eliminate diseases and insect pests, and ensure the smooth growth of wheat.

5. Lack of nutrition

The nutrients needed in different stages of wheat growth and development are different, such as boron and calcium during the growth of wheat pollen. The lack of these two substances will lead to flower abortion and empty spikes. Phosphorus and potassium are needed during the filling stage of wheat, and the lack of these two substances during this period will affect the photosynthesis of wheat, resulting in nutrient synthesis and transport, resulting in empty spikes.

Solution: in planting to ensure the growth of wheat, fertilization should be appropriate to apply some organic fertilizer or farm fertilizer, especially in the later stage of growth must ensure the supply of phosphorus and potassium fertilizer.

The above are the causes and solutions of the empty spike of wheat brought by the pro-agricultural network. I hope it can help you. If you want to know more about wheat, please pay attention to the pro-agricultural network.
