In recent years, wheat production in some major cotton producing areas has changed, mainly in three aspects. First, the sowing date was generally postponed; second, some wheat fields were not sowed with base fertilizer or under-fertilizer application; third, heading or sheet lodging was common in wheat heading filling stage. In response to these problems, production methods need to be changed according to local conditions.
Late-sowing late-onset wheat seedlings are rapidly sensitive to nitrogen, and are sensitive to nitrogen at seedling stage. Late seedlings have fewer tillers, less developed individuals, and fewer total pods per mu. This directly affects yield. For this kind of wheat field, it is necessary to grab the clear and robbing facilities for applying fertilizer and apply 8 kg of urea per acre. Secondly, apply fertilizer based on seedlings and apply 25 kg of ammonium bicarbonate per acre. Third, apply spraying from heading to milking. Potassium dihydrogen phosphate 1 to 2 times, 100-150 grams per acre, to increase the weight of 1000-grain.
To control the fertility of wheat fields with good soil fertility and strong growth, some wheat soils have good soil texture and strong fertility, plus a large amount of peach fertilizers in the former loquat cotton fields, and many residual fertilizers in the field, under suitable temperatures and good environment. Wheat seedlings are easy to grow. If the heading season encounters stormy weather, the plants are prone to lodging. For such wheat fields, the amount of fertilizer should be controlled.
The difference between the seedlings and the reasonable promotion and control of wheat fields with weaker growing conditions can be timely sprayed with Huimanfeng active liquid fertilizer, which promotes early tillering, early earing and early maturation of wheat. For over-enhanced wheat fields, you can use 15% paclobutrazol wettable powder 40-60 grams per gram or 5% uniconazole WP wet 25 to 30 grams, add 40 to 50 kilograms of water spray, control strong and prosperous, prevent plant lodging .
