The newspaper Jinan reported on March 27 that the “spring equinox” had passed and the province’s wheat was continued jointing from south to north. Provincial agricultural experts believe that from now until April 10, it is the critical period for the first application of wheat and spring water.

It is understood that at present, Lunan, southwest of Shandong Province has begun to enter the jointing period; Ludong, Luzhong, Luxi, Lubei wheat in the initial period, will enter the jointing period around April 5. At this time, top-dressing and watering are of great significance.

To this end, on the basis of expert investigation and consultation, the Provincial Department of Agriculture issued an emergency notice yesterday and asked all localities to take the management of the fertilizer and water in the jointing period of wheat as the center of current wheat production, and lay a good foundation for the harvest of summer food.

Experts suggest that most of the wheat in Lunan, southwestern Shandong and other regions have entered the jointing stage and all types of wheat fields must be properly topdressed. For early spring crops such as strong seedlings without topdressing, the amount of topdressing may be appropriately increased, generally 10 to 15 kg of urea per acre topdressing; Application of urea 7 kg -10 kg; for the wheat field that has already caught up with fertilizer, do not top-dressing watering during the jointing period to prevent greediness and lodging.

In regions where there are irrigated conditions, topdressing is best combined with watering to increase fertilizer utilization. Water-free conditions of dryland wheat, if the current situation is better, you can pay attention to using fertilizer. In wheat fields without watering conditions, chemical fertilizers should be applied or ditched to reduce chemical fertilizer losses and improve fertilizer utilization.

In Luzhong, Lubei, and northwestern Shandong, most of the wheat is still in its infancy. The current focus of wheat management: First, spraying strong growth inhibitors such as Zhuangfeng'an in prosperous wheat fields to prevent late lodging. The second is the general field of the second type of seedlings and wheat fields, or early weak seedlings without fertilization, de-fermentation Wangmiao wheat fields, pay close attention to fertilizer. The third is to seize the material preparations. When the wheat enters the jointing stage, the first-class seedlings with better soil fertility will be topped with water.
