Yangmai 13 and Yangmai 16 Spring Control Measures
Yangmai 13 and Yangmai 16 are high quality weak gluten and medium gluten wheat varieties with large planting areas in China. The following points must be mastered in the spring management: Immediately crack down on the land where soil is too soft due to the total amount of straw returned to the soil. , Prevention of freezing and dead seedlings. Due to the imperfections in the ditch system, or through alternate freeze-thaw cycles and erosion by rain and snow, there is a block of collapse and siltation, and the ditch system is immediately dredged to ensure that it can be discharged in spring and when it is dry. Due to the effects of drought, some of the blocks that are not effective before the winter season should be removed and controlled by the “cold tail warmer†according to the grass’s average temperature above 5°C. Insufficient use of basal fertilizer, late sowing or due to drought due to lack of seedlings, seedlings serious field, to seize the rainfall timing of 5 ~ 7.5 kg of urea per acre to promote growth and promote rooting. It is the focus of field management in the spring that Push reapplies joint booting fertilizer, promotes large spikes and large grains, and prevents premature aging. The jointing fertilizer is applied during the inverted 3-leaf stage, that is, when the color of the leaf is faded, the height of the seedling is decreased, and the first internode of the base is basically set to a fixed length, generally in the middle and early March. For medium gluten wheat Yangmai 16, 8 kg of pure nitrogen per acre, 3–4 kg of phosphorus pentoxide, and 5–6 kg of potassium oxide; “Yan fertilizer forward†is adopted for Yangmai 13, a strong gluten wheat. The principle is to apply 3-7 kilograms of pure nitrogen, 3-6 kilograms of phosphorus pentoxide and 5-6 kilograms of potassium oxide per acre to ensure the quality of weak gluten. For early cropping, early fertility, high leaf length, and excessive stem pods, quercetin, paclobutrazol, and other inhibitory growth regulators were applied before jointing to increase lodging resistance. Do a good job in disease prevention and control, timely prevention and control of sheath blight and powdery mildew at the beginning of jointing, and control of head blight at the flowering stage. For example, the main stem and panicle spikes differ greatly during the flowering period, and the control of the head blight is necessary when necessary. Yangmai 13 should strengthen the control of scab.
