Focus on the prevention of wheat fields
First, the wheat field with too early sowing, too large sowing amount, more than 800,000 total stems per mu before wintering, and more than 1 million maximum tillers in spring is easy to cause field canopy, poor ventilation and light transmission, weak basal internodes, and low stem support, which may cause lodging.
The second is that the leaves of wheat are dark green from the beginning to the jointing stage, and the leaves are hypertrophied and draped, and the length of the lower drape is more than 1/3 of the whole leaf.
The third is the wheat field where the first and second nodes of the base of the planted varieties are long, the stalks are weak, the toughness is poor, and the lodging is easy.
Fourth, there is sufficient fertilizer and water, or even excessive, especially the excessive amount of nitrogen fertilizer, resulting in wheat fields with long wheat, long internodes, and weak wheat seedlings.
Precautionary measures
The first is to fertilize and water reasonably. For wheat fields with lodging risk, increase the application of phosphorus and potassium fertilizer, move the nitrogen fertilizer back, and postpone the topdressing watering time to the jointing stage.
The second is timely chemical control. For wheat fields with the possibility of lodging, spray wheat seedlings evenly with 40-50 grams of 15% paclobutrazol per mu, or 30-40 grams of 5% uniconazole, or 15-20 ml of 25% protrusion in the rising stage, mixed with 30-40 kg of water. It should be noted that wheat chemical control must be carried out before jointing, and it will not have the due preventive effect if it is carried out after jointing.
