Latest control measures for wheat with spikes but no seeds
Wheat is one of humanity's staple foods, has a long history of cultivation in our country, and its planting area is also extremely wide. In the process of wheat cultivation, the phenomenon of spikes without seeds has become increasingly serious, severely affecting wheat yield and quality and harming farmers' planting income. So how should the phenomenon of wheat spikes without seeds be controlled? Follow the editor to learn about it.
1. Select excellent varieties
Excellent varieties are the guarantee for achieving a bumper wheat harvest. It is recommended that growers, when selecting varieties, choose varieties that have passed national or provincial variety approval and are suitable for local planting. Before planting, first carry out experimental sowing on a small area, then proceed to promotion and application on a large area, to ensure that the variety is suitable for local planting and to guarantee yield and quality.
2. Prevent cold damage and freezing damage
When selecting varieties, it is necessary to scientifically arrange the appropriate sowing period and sowing rate according to the winter and spring habits of wheat, cultivate strong seedlings, and promote early seedling development. In winter and spring, maintain a reasonable population structure and promote strong individual plants, so as to ensure normal development of flower spikes and improvement of seed-setting rate. It is recommended that farmers spray agents that can improve wheat stress resistance during the jointing stage, which can significantly improve wheat stress resistance and lay a solid foundation for high yield and high quality later.
3. Strengthen field management
Field management should be strengthened to reduce flower degeneration habits, which can effectively increase the number of grains per wheat spike. From the jointing stage to the flowering stage of wheat, potassium dihydrogen phosphate, brassinolide, and boron fertilizer, etc., can be sprayed to supplement nutrients for the plants, improve wheat pollination ability, and timely prevent the occurrence of wheat diseases such as sheath blight, white spike disease, and take-all disease.
4. Scientific use of pesticides
Pesticides should be selected according to the occurrence of diseases and insect pests in the wheat field, so as to avoid waste and pesticide damage. When diluting pesticides, it is recommended to choose the two-stage dilution method to avoid uneven pesticide liquid and cause pesticide damage to wheat. When mixing pesticides, be sure to mix according to the instructions, and do not arbitrarily increase the amount of pesticide used. When spraying, try to avoid the flowering stage. Spraying should be chosen before 10 a.m. or after 4 p.m., avoiding the high-temperature period at noon, so as to avoid pesticide damage. When using herbicides, also choose the right type, use time, and use amount, and note that no herbicide should be used after the jointing stage of wheat.
