due to weather conditions

Since April 20th, there has been continuous rainy weather in many places, and the current wheat is in the heading and flowering period. What effect will it have on wheat at heading and flowering stage? What kind of situation will lead to the reduction of wheat production? And how to manage it after rainfall to make wheat yield high? Let's talk about this topic today.

First of all, wheat is in flowering period, because wheat in this period is sensitive to water. In case of continuous and long-term rainy weather, pollen will be soaked by rain, resulting in poor pollination. Once the pollination of wheat is affected, there will be shriveled grains and empty grains in the later stage (although the ear of wheat is quite large, the grains are not full or even empty, and the quality will be greatly reduced).

Secondly, the continuous rainy weather at flowering stage will aggravate the occurrence of scab, which is often said to be mainly aimed at wheat scab. The flowering period of wheat is the high incidence period of scab, and rainfall will increase the humidity in the field, which provides favorable conditions for the occurrence and outbreak of scab (the glume of wheat is open at flowering period, and in case of continuous rainy weather, the pathogen will enter the glume with the rain, and then propagate and spread, endangering the ears of wheat and ultimately reducing the quality and yield of wheat). Once wheat is infected with scab, it cannot be completely cured, so prevention should be given priority.

Finally, the continuous rainy weather made the wheat not get enough light, and the photosynthesis decreased. At the same time, wheat needs to consume its own energy to keep breathing. Therefore, the ability of wheat to resist pests and diseases at heading and flowering stage is very low, so wheat in this period will be infected with powdery mildew and rust when it encounters continuous rainy weather.

All of the above are the effects of continuous rainy weather on the heading and flowering period of wheat, so it is suggested that you spray the second yield-increasing bag just before seeing flowers as long as you don't enter the full flowering period after rain, which is also the best spraying time after rain. It is suggested that triazole fungicides (pyraclostrobin, epoxiconazole and Tebuconazole) should be selected and then mixed with potassium dihydrogen phosphate, amino acid water-soluble fertilizer and brassinolide. It can not only prevent insects and diseases, but also enhance nutrients for wheat, which can not only provide sufficient energy for wheat flowering and filling, but also prevent premature aging of wheat in the later stage, make wheat sprout big ears and attack big grains, and lay a solid foundation for high yield of wheat.
