Problems solved by technology

Straw burning not only causes environmental pollution, but also reduces the activity of microorganisms on the soil surface (Ruiji Yang, Hailing Ma, Qifeng Yang, et al. Effects of planting density and nitrogen application rate on soil microbial activity of rape as fodder for multiple cropping with wheat stubble. Journal of Applied Ecology, 2007, 18(1) :113-117.)
At the same time, the soil surface is exposed in spring and winter, which is easy to form surface runoff and soil erosion, leading to the deterioration of the ecological environment (Luo Zhuzhu, Huang Gaobao, Xin Ping, et al. Comparative analysis of surface soil structure and organic carbon content of different conservation tillage methods in Longzhong dryland . Agricultural Research in Arid Areas, 2008, 26(4): 53-58.)

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.

Abstract

The invention relates to a sowing technique, in particular to a stub-leaving no-tillage mechanical sowing cultivation method. The stub-leaving no-tillage mechanical spring-manure wheat sowing cultivation method comprises the steps of harvesting wheat, irrigating in winter, performing medical treatment on selected spring-manure wheat seeds, mixing the selected spring-manure wheat seeds with chemical fertilizer, performing stub-leaving no-tillage mechanical spring-manure wheat sowing, performing field management of stub-leaving no-tillage spring-manure wheat, and performing stub-leaving no-tillage spring-manure wheat harvesting and the like. The method has the advantages of increasing moisture in soil, reducing wind corrosion and waster and soil loss, regulating ground temperature, increasing nutrients in soil, improving activity of soil enzymes and the like.

Description

technical field [0001] The invention relates to a sowing technology, in particular to a sowing and cultivation method of a stubble no-tillage machine. Background technique [0002] Crop straw is one of the most abundant renewable resources in agricultural production. The northern wheat planting area in my country is rich in crop straw, but the straw utilization technology in this area is backward, the resource conversion rate is low, and the problems such as insufficient recycling are prominent. In recent years, due to the replacement of livestock by agricultural mechanization, coal and liquefied gas instead of straw as fuel, and the difficulty of stubble removal by combine harvesters, straw burning has become very common. The wheat planting area in the north of our country has little rainfall, with an annual rainfall of 36-160 mm. The straw is returned to the field and turned into the ground, which is not easy to rot. In order not to affect the plowing and sowing of the ne...
