Key pests and diseases in the middle and late stages of wheat
Pouring the water to the mother's ear and picking up the flag should be scientifically managed according to the soil moisture. All wheat fields with dry soil and lack of moisture must concentrate on watering. Especially for the plots that affect the normal growth and development of wheat, it is necessary to take effective measures and strive to pour one time before the end of April. Wheat fields with good soil moisture can be postponed to the end of the wheat and the early flowering stage.
Pouring the grout water After the wheat is flowered, it enters the wheat filling stage. In this period, the temperature is high and the water evaporation is large. The central task of wheat field management is to raise the leaves and ensure the normal photosynthesis of wheat. Roots must have sufficient water supply to make the root system not prematurely decay and absorb water and fertilizer. Therefore, be sure to pour the grout water. In particular, the wheat that is used as the autumn crop in the wheat field should be combined with the normal emergence of autumn crops. For high-quality and strong gluten wheat, it is necessary to pay attention to pouring the flag of the booting water or flowering water, pouring the water as early as possible or not, and not pouring the wheat yellow water to ensure the quality of the wheat.
Do a good job in the prevention and control of wheat pests and diseases. For the plots with large nitrogen fertilizer application and depressing fields, it is necessary to strengthen the prevention and control of wheat powdery mildew. At the same time, we must pay close attention to the occurrence of wheat rust. Control wheat stubble, disable high-toxic and high-residue pesticides such as methamidophos and omethoate, use 40% of Lego emulsifiable concentrate 140g or 33% of water to kill 40g of chloro-emulsifiable concentrate, add 10% of imidacloprid 20g, to water 30 kg spray. In the flowering period of wheat, in case of rainy weather, attention should be paid to the control of wheat scab. Can use 50% carbendazim WP 80g to spray 30kg of water.
