Embodiment 1
[0029] Embodiment 1: a kind of cultivation method of stubble no-till mechanical sowing spring wheat comprises the following steps:
[0030] 101. Wheat harvesting: Wheat is harvested mechanically. The height of wheat stubble is 25-30 cm, and the amount of stubble accounts for 48-52% of the total straw. The land is not plowed before the next spring wheat is sown;
[0031] 102. Winter irrigation: Winter irrigation is carried out on October 20-30 every year in the northern wheat planting area of my country, and the irrigation volume is 100-110 mm;
[0032] 103. Perform drug treatment on the selected spring wheat seeds; select no-tillage spring wheat seeds with stubble and no-tillage with strong tillering ability, uniform particles, no impurities, and a germination rate of not less than 85%; mainly select Yongliang No. 4;
[0033] 104. Mix the selected spring wheat seeds with chemical fertilizers, the weight ratio of wheat seeds: chemical fertilizers is 1:1.5-1.7; the chemical fe...
Embodiment 2
[0040] Embodiment 2: Same as Example 1, the difference is: in step 107, during the jointing period of no-tillage spring wheat with stubble, 8-10 g of Jinggangmycin and 50-60 kg of water are mixed per mu, and the base of wheat seedlings is sprayed to prevent and control grain blight; in the early flowering stage of spring wheat, mix 35-40ml of carbendazim wettable powder with a concentration of 50% and 42-48kg of water per mu, and spray the stems and leaves to effectively eliminate scab; - Mix 45-55ml of 20% imidacloprid wettable powder with 25-30kg of water, spray on stems and leaves to prevent and control aphids.
Embodiment 3
[0041] Embodiment 3: same as embodiment 1, the difference is: the drug treatment described in the step 103 step, concentration 6% Li Kexiu 30-40g and 1.5-2kg water are mixed and mixed with 100kg of spring wheat seeds.
