The results of the study indicate that whether it is high-yield or medium- and low-yield wheat fields, the application of zinc fertilizer has a significant increase in yield. Moreover, Xiaxia summer corn can also use the aftereffect of zinc fertilizer in wheat fields to continue to increase production.
The application of zinc fertilizer in wheat field is beneficial to the absorption of phosphorus by wheat, can promote the growth of wheat root system, increase the tillering, the wheat field grows neatly, the leaf color is green, the resistance is strong, and the grain weight per spike is improved.
The method of applying zinc fertilizer in wheat field includes basic fertilizer, seed dressing, soaking, and spraying. In particular, the application of basal fertilizer is best. Because the key period of winter wheat absorption of zinc fertilizer is in the seedling stage and the beginning period, so early application of zinc in wheat fields is better than late. Zinc fertilizer is used as base fertilizer, and 25% of the season wheat can be used. Part of the zinc fertilizer left in the soil is activated and absorbed by the lower corn in the summer, and thus can be used as a “fertilizer for wheat†and wheat and summer corn. Can increase production purposes.
Zinc in wheat fields is best applied in combination with nitrogen and phosphate fertilizers. In middle- and high-yield plots with a yield of 350 kilograms per mu, 8 kg of pure nitrogen is applied per mu, 4 kg of phosphorus pentoxide, 2 kg of zinc sulphate, and phosphorus and zinc are used. All fertilizers were used as basal fertilizers, and nitrogen fertilizers were applied in divided doses. Base fertilizer was used as 40% of the nitrogen fertilizer index, and 60% was used as topdressing in wheat fields. Specific application method: When wheat is sown and soil-smeared, mix the prepared nitrogen, phosphorus, and zinc fertilizers and mix well, spread it on the surface, and then plow it.
