Bainong dwarf resistance 58 spring management points
Bainong dwarf resistance 58 is prominently overwhelming. It should adopt management measures to promote early delivery, promote growth in the medium term, and promote panicle weight in the later period.
First, water management (a) early pouring back to Qingshui. After the soil is thawed, pour water once in a timely manner. (B) heavy pouring heading water. Watering once in the early stage of heading can promote the elongation of the lower section of Pak-Nan-Kang-Yi58 ear, which is conducive to the operation of nutrients at later stages. (c) Lightly pouring grouting water. Watering once in the filling stage can increase grain weight and increase yield.
Second, a reasonable fertilization (a) topdressing back green manure. In combination with pouring green water, topdressing 15 to 20 kg of urea per acre. (b) Qiao Shi grain fertilizer. Combining heading water with 5 to 10 kg of urea per acre, to extend the functional period of the leaves, promote grouting and increase grain weight. (c) Spray foliar fertilizer. In the jointing stage to the heading stage, 2 to 3 times of foliar fertilizer should be sprayed, spraying 0.75 to 1 kg of urea and 0.2 to 0.3% of monobasic potassium dihydrogen phosphate 50 to 75 kg per mu.
Third, comprehensive prevention and control of diseases and weeds Bainong dwarf resistance 58 high resistance to stripe rust, powdery mildew, stem rust, in the resistance to sheath blight. Therefore, the emphasis in the spring is on the control of aphids, spider mites and leaf rust, scab, and wheat field weeds.
